(Embodiment)
The structure of the massage machine 1 provided with the body condition evaluation apparatus is demonstrated using FIG.
The massage machine 1 includes a main body 10, a treatment unit 20, an operation unit 30, and a control unit 40.
The main body 10 includes a seat portion 11 that supports the buttocks of the user (user), a backrest portion 12 that supports the back surface of the user, and an ottoman 13 that supports the lower limbs of the user.

  Inside the backrest 12, a rail 12 </ b> A is arranged along the longitudinal direction Y of the backrest 12. The treatment part 20 is attached to the rail 12A so as to be movable on the rail 12A.

  The treatment unit 20 includes a treatment block 21, an arm 25, and a treatment element 26 (a kneading ball). A treatment element 26 is attached to the end of the arm 25. In the present embodiment, the treatment element 26 also functions as a load presentation unit that applies a load to the user when sensing stiffness symptoms.

  As shown in FIG. 2, the treatment block 21 includes a vertical drive unit 211, a width drive unit 212, and a strength drive unit 213. Each of the vertical drive unit 211, the width drive unit 212, and the strength drive unit 213 includes a position sensor that detects the position of the treatment element 26, a sensor that detects the speed of the treatment element 26, and motors M1, M2, and M3. ing.

  The treatment block 21 is attached to the rail 12 </ b> A via the vertical drive unit 211. The vertical drive unit 211 has a rotation shaft on which a gear is formed. The axial direction of the rotation axis is along the lateral direction X of the massage machine 1. A motor M1, which is an actuator, is connected to the rotating shaft. The gear is meshed with a rack formed on the rail 12A so that the gear can move on the rail 12A. When the motor M1 rotates, the treatment block 21 moves in the vertical direction Y on the rail 12A according to the rotation direction of the motor M1.

The arm 25 is attached to the treatment block 21 via the width driving unit 212 and the strength driving unit 213.
The width driving unit 212 is configured by, for example, a ball screw. The width driving unit 212 is provided with a motor M2 that is an actuator on a rotating shaft extending in a horizontal direction X orthogonal to the vertical direction Y. As the motor M2 rotates, the arm 25 moves in the lateral direction X.

  The strength and weakness drive unit 213 has a rotation shaft formed with gears and extending in the lateral direction X. A motor M3 that is an actuator is connected to the rotating shaft. An arm 25 is provided on a gear that meshes with the gear of the rotating shaft. The motor M3 rotates the arm 25 in the lateral direction X, and operates the treatment element 26 in a direction in which the treatment element 26 is pressed against the back side of the user and in a direction opposite to the pressing direction.

The user is massaged by the operation of the treatment element 26 driven by the vertical drive unit 211, the width drive unit 212, and the strength drive unit 213.
The treatment element 26 is a cylindrical member having a circular cross section. A plurality of elastic members having different hardnesses are laminated in a radial direction (radial direction) so as to be integrated.

The vertical drive unit 211, the width drive unit 212, and the strength drive unit 213 operate based on a signal from the treatment element control unit 41 described later.
The operation unit 30 includes a massage course selection unit and a start button.
The selection part of a massage course is used in order to change the body part (for example, a neck, a shoulder, a back, and a waist) of a user, and the strength of a massage.

  The start button is used to start a massage course. When the massage course is started, the massage machine 1 performs a massage in which a plurality of types of massage techniques (for example, fir, acupressure, brushing, and hitting) are sequentially combined on a plurality of parts of the body. Run.

Further, as shown in FIG. 3, the operation unit 30 is provided with an output unit 31 and a biological physiological information measurement unit 32.
The output unit 31 is configured by a display or the like, and outputs an evaluation result of the body information of the user.

  The biological physiological information measuring unit 32 measures an index related to stiffness, blood circulation, fatigue, pain, and the like related to the effect and effectiveness of the massage. In the present embodiment, skin electrical reflection (Galvanic Skin Response: GSR) relating to the amount of sweat is measured by the biological information sensor. Since sweating occurs when a site with stiffness or pain is treated, this amount of sweating can be used as biophysiological information. In this GSR information, electrodermal activity (EDA) and electrodermal reaction (EDR) are used. In the present embodiment, the biophysiological information measurement unit 32 calculates an electrical skin reaction (EDR) together with the amount of change in EDA. Then, the biological physiological information measuring unit 32 supplies GSR information (EDA, EDR) to the control unit 40.

As shown in FIG. 3, the control unit 40 includes a treatment element control unit 41 as a load adjustment unit and an evaluation unit 42.
The treatment element control unit 41 controls the vertical drive unit 211, the width drive unit 212, and the strength drive unit 213. Further, the treatment element control unit 41 acquires information related to the treatment position of the treatment element 26 from the vertical drive unit 211, the width drive unit 212, and the strength drive unit 213.

  The treatment element control unit 41 holds pattern information in which a massage pattern is recorded according to a massage course. In the massage pattern, a plurality of places (sensing points) for grasping stiffness symptoms are set. Furthermore, the treatment element control unit 41 holds information on the load force used for grasping stiffness symptoms. As the load force, a plurality of loads (low load, medium load, high load, etc.) are used according to the stiffness symptoms. In this embodiment, a case where a low load is used as the first sensing pattern and a medium load is used as the second sensing pattern will be described.

  Furthermore, the treatment element control unit 41 holds information related to treatment contents to be performed according to stiffness symptoms. In the present embodiment, the information regarding the tender point treatment pattern and the cure treatment pattern is held as the treatment content. Furthermore, when the stiffness symptom cannot be resolved by the treatment of the tender point treatment pattern and the induration treatment pattern, adjustment information for correcting the treatment content (procedure and power) is held.

Further, as shown in FIG. 2, the treatment element control unit 41 is connected to a force detection unit 214 and a physique detection unit 215.
The force detection unit 214 detects a physical quantity that the treatment element 26 receives from the user. Here, the distance from the center of the treatment element 26 to the user when the surface of the treatment element 26 is in contact with the user and is not deformed is referred to as a “reference distance”. The difference between the reference distance and the reference distance when approaching the user is referred to as the “displacement amount” of the treatment element 26. The displacement amount when the treatment element 26 is at the reference position is “0”. The distance from the backrest 12 to the center of the treatment element 26 is defined as the “projection amount” of the treatment element 26. Furthermore, the magnitude of the force for pressing the treatment element 26 against the user is defined as the “pressing force” of the treatment element 26. And the force detection part 214 detects the repulsive force (load force) from the user at the time of massaging as a mechanical physical quantity according to the pressing force.

  As the force detector 214, a strain gauge, a measuring device for measuring the displacement of the elastic body, or the like can be used. Then, the force detection unit 214 outputs a load force detection signal detected by the treatment element 26 to the treatment element control unit 41.

  Further, the physique detection unit 215 detects the general physique of the user. To detect this physique, first, the user sits on the seat 11 and leans against the backrest 12 and moves the treatment element 26 up and down while pressing the treatment element 26 against the person to be treated. The position of is determined. The position of the shoulder or waist is determined by a method of determining from the position in the front-rear direction when the treatment element 26 is moved in the vertical direction while keeping the force received by the treatment element 26, or in the vertical direction while maintaining a constant position in the front-back method. The method of judging from the force at the time of moving to is mentioned.

  Moreover, the detection with respect to the left-right direction of a body is also possible with the same structure. Specifically, since the human body has a convex shape with the spine (center) at the apex in the left-right direction of the back, if the position is changed away from the spine in the left-right direction, the force pressing the user is small. Become. In addition, a piezoelectric sensor may be provided in the seat part 11 and the backrest part 12, and the physique detection part 215 may detect a physique with this piezoelectric sensor.

As shown in FIG. 3, the evaluation unit 42 includes a treatment site determination unit 421, a body condition evaluation unit 422, and an evaluation result storage unit 423.
The treatment site determination unit 421 acquires information (position information) about the position where the treatment element 26 is operating from the treatment element control unit 41. And the treatment site | part discrimination | determination part 421 specifies a treatment site | part based on this positional information. Further, the treatment site determination unit 421 acquires the load force (physical quantity information) in the treatment element 26 from the treatment element control unit 41.

  The body state evaluation unit 422 acquires information related to biological reactions. In the present embodiment, information (treatment site information, physical quantity information) acquired from the treatment element control unit 41 and GSR information (EDA, EDR) acquired from the biological physiological information measurement unit 32 are acquired. Then, the body condition evaluation unit 422 evaluates the body condition of the treatment site based on the acquired plurality of biological reactions (here, biological physiological information). Therefore, the body state evaluation unit 422 holds biological state determination information for determining stiffness symptoms according to the magnitude of each load applied to the treatment element 26. In this biological state determination information, information related to a threshold value for determining the magnitude of the biological reaction is set for the magnitude of the load (for example, three types of low load, medium load, and high load). Then, the body state evaluation unit 422 determines a stiffness symptom (none, tender point, induration, chronic) according to the biological reaction using the biological state determination information. Details of the relationship between the load and stiffness symptoms will be described later. Furthermore, the body condition evaluation unit 422 displays the evaluation result (the determination result of the body condition and stiffness symptoms) on the output unit 31.

  The evaluation result storage unit 423 records the results (body state and stiffness symptoms) evaluated by the body state evaluation unit 422. The evaluation result storage unit 423 records the evaluation results before and after the massage for each treatment site (sensing point). In the present embodiment, a “tenderness point” flag, a “hardening” flag, and the like are recorded as stiffness symptoms.

(Relationship between biological physiological information and physical condition)
The relationship between the biological physiological information (for example, GSR, skin temperature, and pulse rate) detected by the biological information sensor and the body state of the user will be described. Depending on the degree of autonomic nervous system activity, changes in GSR, skin temperature, and pulse rate vary.

  Here, when the activity is low, the GSR and the pulse rate decrease, and the skin temperature increases. When the activity is slightly low, the GSR is in a sideways state, but the skin temperature increases and the pulse rate decreases. When the activity is slightly high, the GSR rises from a sideways state, the skin temperature decreases, and the pulse rate increases. Furthermore, when the activity is high, the GSR increases greatly, the skin temperature decreases, and the pulse rate increases.

  As described above, when the biological physiological information changes, the body state of the user can be estimated as a relaxed and comfortable state when the activity level is low. Further, when the activity level is slightly high, it can be estimated that the body state is a mixture of both “painful” and “comfortable”, which are unique emotions received when, for example, massaging a stiff portion. On the other hand, when the activity is high, it can be estimated that the person feels “pain”. Further, when the activity is neutral, it can be estimated that the neutral state is “no comfort or pain”.

(Relationship between biological reactions and stiffness symptoms)
Next, the relationship between the biological reaction and stiffness symptoms will be described with reference to FIGS. Biological physiological information and physical quantity information can be used for this biological reaction.

  FIG. 4 shows the relationship of the magnitude of the biological reaction (biological reaction amount) with respect to three types of loads (low load, medium load, and high load) having different magnitudes. In the case of a low load, when there is no stiffness symptom, there is a tendency to show a response smaller than the threshold value, but when there is a stiffness symptom (tenderness point to chronic), the response tends to be large. In the case of medium load, there is a tendency to show a response larger than the threshold when there is no stiffness symptoms or at the tender point, but there is a tendency for the response to become small in the case of induration or chronicity. Further, in the case of high load, when there is no stiffness symptoms, tender point, and induration tend to show a response larger than the threshold value, but in the case of chronic, the response tends to be small. Thus, when there is a stiffness symptom, it can be determined by a low load. Furthermore, tender points and induration can be identified by medium load. Induration and chronicity can be distinguished by high load.

  When a load is applied at the time of sensing, it is preferable that parameters other than the magnitude of the load be the same. As parameters other than the load force, there are a position, an operation trajectory (an operation direction in a vertical plane with respect to the pushing direction of the treatment element 26), a speed, the number of times, and the like. Thereby, the influence of parameters other than a load can be suppressed and the determination accuracy can be increased.

  FIG. 5 shows the time change of the biological reaction when a load is applied. In this embodiment, as shown to Fig.5 (a), it provides so that load may become fixed. In this case, as shown in FIG. 5B, after the biological response has leveled off, the statistical value of the biological reaction for a predetermined specified time is used. Since the biological reaction has fluctuations that change with time, the determination accuracy of the body state can be increased by using the statistical value of the biological reaction when the load becomes constant.

(Massage processing operation)
The operation of the massage process will be described with reference to FIGS. 6 and 7 for the massage machine 1 configured as described above. Here, it is assumed that treatment is performed by determining “no stiffness symptoms”, “tenderness point”, and “hardening” by using low load and medium load.

  First, as shown in FIG. 6, the control unit 40 executes a sensing point setting process (step S01). Specifically, the treatment element control unit 41 of the control unit 40 acquires information related to the massage course set in the operation unit 30. And the treatment element control part 41 pinpoints the position of a sensing point in the treatment point contained in a massage course based on a physique detection of a user.

  Next, the control part 40 performs a 1st sensing process (step S02). Specifically, the treatment element control unit 41 of the control unit 40 performs sensing using the first sensing pattern. Here, sensing with a low load is performed as the first sensing pattern. Then, the treatment element control unit 41 supplies information on the load force and the sensing point to the evaluation unit 42. In this case, the treatment site determination unit 421 of the evaluation unit 42 identifies the treatment site. Furthermore, the treatment site determination unit 421 supplies information regarding the load force to the body condition evaluation unit 422. The body state evaluation unit 422 acquires a biological reaction amount at the time of the first sensing. In the present embodiment, sweating amount GSR information is acquired from the biological physiological information measuring unit 32 as the biological reaction amount.

  Next, the control part 40 performs the determination process about whether a biological reaction amount is more than a threshold value (step S03). Specifically, the body condition evaluation unit 422 of the control unit 40 compares the acquired biological reaction amount with a threshold value in the first sensing pattern (low load).

  When it determines with the amount of biological reactions being smaller than a threshold value (in the case of "NO" in step S03), the control part 40 determines a sensing point as a non-treatment point (step S04). Specifically, the body condition evaluation unit 422 of the control unit 40 records a “no stiffness symptoms” flag in the evaluation result storage unit 423 in association with the part identifier of the sensing point. And the body condition evaluation part 422 notifies that it is a non-treatment point with respect to the treatment element control part 41. FIG. Further, the body condition evaluation unit 422 displays the stiffness symptoms about the sensing points on the output unit 31. Details of this display will be described later.

  Next, the control part 40 performs the movement process to another point (step S05). Specifically, the treatment element control unit 41 of the control unit 40 moves the treatment element 26 to another sensing point.

  On the other hand, when it determines with the amount of biological reactions being more than a threshold value (in the case of "YES" in step S03), the control part 40 determines a sensing point as a treatment point (step S06). Specifically, the body condition evaluation unit 422 of the control unit 40 notifies the treatment element control unit 41 that it is a treatment point.

  Next, the control part 40 performs a 2nd sensing process (step S07). Specifically, the treatment element control unit 41 of the control unit 40 performs sensing using the second sensing pattern. Here, sensing with a medium load is performed as the second sensing pattern. Then, the treatment element control unit 41 supplies information regarding the load force and the sensing point to the evaluation unit 42. In this case, the treatment site determination unit 421 of the evaluation unit 42 identifies the treatment site. Furthermore, the treatment site determination unit 421 supplies information regarding the load force to the body condition evaluation unit 422. The body state evaluation unit 422 acquires a biological reaction amount at the time of the second sensing.

  Next, the control part 40 performs the determination process about whether a biological reaction amount is more than a threshold value (step S08). Specifically, the body condition evaluation unit 422 of the control unit 40 compares the acquired biological reaction amount with a threshold value in the second sensing pattern (medium load).

  When it is determined that the biological reaction amount is equal to or greater than the threshold value (in the case of “YES” in step S08), the control unit 40 determines the sensing point as a tender point (step S09). Specifically, the body condition evaluation unit 422 of the control unit 40 records a “tenderness point” flag in the evaluation result storage unit 423 in association with the part identifier of the sensing point. Then, the body condition evaluation unit 422 notifies the treatment element control unit 41 that it is a tender point. In this case, as will be described with reference to FIG. 7, treatment corresponding to the tender point is performed (B). Also in this case, the body condition evaluation unit 422 displays the stiffness symptom about the sensing point on the output unit 31 as described later.

  On the other hand, when it is determined that the biological reaction amount is smaller than the threshold value (in the case of “NO” in step S08), the control unit 40 determines that the sensing point is consolidation (step S10). Specifically, the body condition evaluation unit 422 of the control unit 40 records a “hardening” flag in the evaluation result storage unit 423 in association with the part identifier of the sensing point. Then, the body condition evaluation unit 422 notifies the treatment element control unit 41 that it is induration. In this case, as will be described with reference to FIG. 7, treatment corresponding to induration is performed (A). Also in this case, the body condition evaluation unit 422 displays the stiffness symptom about the sensing point on the output unit 31 as described later.

Next, the processing when it is determined as induration (A) or tender point (B) will be described with reference to FIG.
The control part 40 performs the treatment process for hardening with respect to the sensing point determined to be hardening (step S20). Specifically, the treatment element control part 41 of the control part 40 performs massage using the treatment pattern for caking.

  Next, the control part 40 performs a 2nd sensing process similarly to step S07 (step S21). Also in this case, the body condition evaluation unit 422 acquires a biological reaction amount at the time of the second sensing.

  Next, the control part 40 performs the determination process about whether a biological reaction amount is more than a threshold value (step S22). Specifically, the body condition evaluation unit 422 of the control unit 40 compares the acquired biological reaction amount with a threshold value in the second sensing pattern (medium load).

  If it is determined that the amount of biological reaction is not equal to or greater than the threshold value (in the case of “NO” in step S22), the control unit 40 determines that consolidation has not been resolved (step S23). Specifically, the body condition evaluation unit 422 of the control unit 40 notifies the treatment element control unit 41 that consolidation has not been solved.

  Next, the control unit 40 performs adjustment processing (step S24). Specifically, the treatment element control unit 41 of the control unit 40 adjusts the treatment content (procedure and force) in the treatment for this sensing point. In step S20, the hardening treatment process is executed using the adjusted hardening treatment pattern.

  On the other hand, when it determines with the amount of biological reactions being more than a threshold value (when it is "YES" in step S22), the control part 40 determines with symptom relief (step S25). Specifically, the body state evaluation unit 422 of the control unit 40 determines that the induration has eased from hardening to tenderness. Then, the body condition evaluation unit 422 records a “tenderness point” flag in the evaluation result storage unit 423 in association with the part identifier of the sensing point. Then, the body condition evaluation unit 422 notifies the treatment element control unit 41 that it is a tender point. Also in this case, the body condition evaluation unit 422 displays the stiffness symptom about the sensing point on the output unit 31 as described later.

  In this case, the control unit 40 executes a tender point treatment process (step S26). Specifically, the treatment element control unit 41 of the control unit 40 performs massage using the tender point treatment pattern. In addition, also when it determines with a sensing point being a tender point in step S09 (B), the treatment process for tender points is performed.

  Next, the control part 40 performs a 1st sensing process similarly to step S02 (step S27). Also in this case, the body condition evaluation unit 422 acquires the biological reaction amount at the time of the first sensing.

Next, the control part 40 performs the determination process about whether a biological reaction amount is more than a threshold value similarly to step S03 (step S28).
If it is determined that the amount of biological reaction is equal to or greater than the threshold (in the case of “YES” in step S28), the control unit 40 determines that the tenderness point has not been resolved (step S29). Specifically, the body condition evaluation unit 422 of the control unit 40 notifies the treatment element control unit 41 that tenderness has not been resolved.

  Next, the control unit 40 executes adjustment processing (step S30). Specifically, the treatment element control unit 41 of the control unit 40 adjusts the treatment content (procedure and force) in the treatment for this sensing point. Then, the process returns to the tender point treatment process (step S26). Here, the tender point treatment process is executed using the adjusted tender point treatment pattern.

  On the other hand, when it determines with the amount of biological reactions not being more than a threshold value (in the case of "NO" in step S28), the control part 40 determines with a tenderness point elimination (step S31). Specifically, the body condition evaluation unit 422 of the control unit 40 records a “no stiffness symptoms” flag in the evaluation result storage unit 423 in association with the part identifier of the sensing point. Then, the body condition evaluation unit 422 notifies the treatment element control unit 41 of the cancellation of the tender point. Also in this case, the body condition evaluation unit 422 displays the stiffness symptom about the sensing point on the output unit 31 as described later.

  Next, the control part 40 performs the movement process to another point (step S32). Specifically, the treatment element control unit 41 of the control unit 40 moves the treatment element 26 to another sensing point.

  Next, the display screen 500 displayed on the output unit 31 will be described with reference to FIG. In this display screen 500, the display form such as color is changed and displayed for each sensing point 501 in the user image so that stiffness symptoms can be identified. Here, a point with dark color represents “hardening”, a point with medium color represents “tenderness point”, and a point with light color represents “no stiffness”.

According to the massage machine 1 of the present embodiment, the following effects can be obtained.
(1) In the present embodiment, stiffness symptoms are determined using a plurality of sensing patterns. Thereby, a stiffness symptom can be determined accurately and appropriate treatment can be performed.

  (2) In the present embodiment, when a load is applied during sensing, parameters other than the magnitude of the load are kept the same. Thereby, it can avoid that another parameter influences a biological reaction, and can improve the determination precision of a biological condition.

  (3) In the present embodiment, the body condition evaluation unit 422 acquires the sweating amount GSR information from the biological physiological information measurement unit 32 as the biological reaction amount. Thereby, it is possible to accurately measure a biological reaction.

  (4) In the present embodiment, a statistical value of a biological reaction for a predetermined time after the load becomes constant is used. Thereby, a stable biological reaction can be obtained and the determination accuracy of the body state can be increased.

  (5) In the present embodiment, the second sensing process (step S07) is executed after the first sensing process (step S02). Accordingly, it is possible to exclude sensing points that do not require treatment by the first sensing process (step S02). Furthermore, if a high load is applied first, the influence of the stimulus remains and there is a possibility that a sufficient biological reaction cannot be obtained at a low load. By performing the first sensing process with a low load first, it is possible to accurately evaluate stiffness symptoms.

  (6) In the present embodiment, the control unit 40 executes the second sensing process (step S07). In the second sensing process with a medium load, the tender point and the hardened state can be identified, so that appropriate treatment according to the stiffness symptom can be performed.

(7) In the present embodiment, the control unit 40 displays stiffness symptoms on the output unit 31 during each sensing process. Thereby, a user can grasp | ascertain a physical state.
(8) In the present embodiment, when it is determined that it is hardened, the control unit 40 executes a hardening treatment process (step S20). When it determines with a tender point, the control part 40 performs the treatment process for a tender point (step S26). Thereby, the treatment corresponding to the stiffness symptom can be performed. Further, when it is determined that consolidation has not been resolved and tenderness point has not been resolved (steps S23 and S29), the control unit 40 performs adjustment processing (steps S24 and S30). Thereby, further treatment can be performed according to the treatment effect.

(Modification)
The specific form that can be taken by the body condition evaluation apparatus is not limited to the form presented in the above embodiment. This body condition evaluation apparatus can take various forms different from the above-described embodiments within a range in which the object of the present invention is achieved. The modified example of the said embodiment shown below is an example of the various forms which this massage machine can take.

  -Although it applied to the chair type massage machine 1 as a body condition evaluation apparatus in the said embodiment, it is not limited to a chair type, It can also apply to another form. Other forms include, for example, a bed-type massage machine or a dedicated device that performs only evaluation.

  In the above embodiment, biophysiological information (sweat amount GSR information) is used as a biological reaction. However, the index is limited to the sweat amount GSR information as long as it is an index related to stiffness, blood circulation, fatigue, and pain related to the effectiveness of massage. Is not to be done. For example, muscle hardness, blood flow, skin temperature, heart rate (pulse), electromyogram (muscle fatigue evaluation), etc. can be used. It is also possible to use a physical quantity (such as muscle hardness) according to the load force.

  In the above embodiment, the operation unit 30 is provided with the biological physiological information measurement unit 32. The measurement method of biological physiological information is not limited to this form. For example, a biological physiological information measuring unit 32 may be provided separately from the operation unit 30. The biological physiological information measuring unit 32 may be arranged around the treatment element 26 and moved together with the treatment element 26. Moreover, it is not limited to the case where biophysiological information is acquired by wire, but is acquired wirelessly using a terminal (for example, a portable terminal of a user) that can wirelessly communicate with the massage machine 1. Also good. In this case, the evaluation unit 42 of the massage machine 1 acquires biophysiological information measured at the terminal by wireless communication.

  In the above embodiment, the control unit 40 executes the first sensing process (Step S02) and the second sensing process (Step S07). In addition to this, the third sensing process may be executed. In this case, in the third sensing pattern, the body state evaluation unit 422 holds information related to the threshold value of the biological reaction amount that distinguishes between hardening and chronicity at the time of high load. Then, in the second sensing process (step S07), when it is determined that the biological reaction amount is smaller than the threshold value (in the case of “NO” in step S08), the third sensing process is performed. In the third sensing process, induration and chronic are discriminated using a biological reaction amount at high load. Specifically, when the biological reaction amount at high load is smaller than the threshold value of the third sensing, it is determined to be chronic, and when the biological reaction amount is equal to or greater than the threshold value, it is determined to be hardened. Thereby, chronic stiffness symptoms can be determined.

In the above embodiment, the output unit 31 displays the degree of stiffness at the sensing point 501 in the user image. The display method is not limited to this.
As shown in the display screen 510 shown in FIG. 9, it is also possible to use a form in which the evaluation results before and after the massage of each part are quantified and notified. Here, “0” to “20” represents “no stiffness”, “20” to “70” represents “tenderness point”, and “70” to “100” represents “hardening”. By using numerical values, it is possible to quantitatively grasp changes in the degree of stiffness.

  Moreover, as shown in FIG. 10, it is also possible to display the evaluation results before and after the massage. A display screen 521 in FIG. 10A shows a state before massage, and a display screen 522 in FIG. 10B shows a state after massage.

  Further, as in the display screen 530 shown in FIG. 11, it is also possible to display the evaluation results by collecting sensing points. In this display screen 530, sensing points of induration with severe symptoms (sensing points near the shoulder in FIG. 11) are collectively displayed in an area 531. On the other hand, sensing points 501 with mild symptoms are individually displayed. Since induration is a symptom that can be seen continuously over a relatively wide range, displaying tender points as points and induration in areas makes it easier to visually grasp.
