  When using the trunk extension muscle strength measuring device of this embodiment, first, as shown in FIG. 3, a person to be measured (or a trainee) T holds the two shoulder belts 1e of the cushion 1 on both shoulders. Each shoulder belt 1e is hung with the buckle 1d and the power switch of the operation unit 2h of the controller 2 is turned on to display the menu screen on the display unit 2e. Then, the airbag 1a is still filled with air. If there is not, the operation part 2h is operated to switch the air to fill the airbag 1a of the cushion 1 with air to a predetermined air pressure, and then the operation part 2h is used to select the operation menu. 4, the person T to be measured sits on the floor F or the like with the back facing the wall W or the like, and the cushion 1 is sandwiched between the back and the wall W or the like. When the back portion is pressed against the pressure-receiving surface provided with the pressure-sensitive sensor 1c in the first embodiment, the cushion 1 is elastically compressed between the back portion and the wall surface W as shown by the phantom line in FIG. 1c is supported by the pad 1b and pressed against the back, so that the pressure-sensitive sensor 1c detects the pressure P received from the back at each part and outputs it as a signal indicating the pressure of each part. The output signal of the sensor 1c is processed as described above, and the trunk extension muscle strength of the measurement subject who presses the back portion is obtained as the total value of the pressure from the back portion, and the obtained result is output as the measurement result. .

  Therefore, according to the trunk extension muscle strength measuring device of this embodiment, when the person to be measured T is a round person such as an elderly person, the cushion 1 is elastically compressed and deformed corresponding to the circular back, Since the pressure-sensitive sensor 1c detects the pressure due to the muscular force in the deformed state, the measurement can be performed without extending the back, and the burden on the person T to be measured can be reduced.

  Moreover, according to the trunk extension muscle strength measuring device of this embodiment, the cushion 1 is attached to the body of the person to be measured T, and the pressure receiving surface provided with the pressure-sensitive sensor 1c of the cushion 1 is the back of the person to be measured T. Since the shoulder belt 1e is provided so that the pressure receiving surface is detached from the back of the person to be measured T due to the elastic compressive deformation of the cushion 1 during measurement or training, the shoulder belt 1e is used. It is possible to prevent this, and even a person with a motor function disorder can safely and reliably perform muscle strength measurement and training.

  Furthermore, according to the trunk extension muscle strength measuring device of this embodiment, the manual relief valve 2b that holds the air filled inside the airbag 1a of the cushion 1 so as to be able to be discharged to the outside is provided. Is operated to release the air inside the airbag 1a of the cushion 1 into the atmosphere, so that the cushion 1 is flattened to improve the portability of the apparatus, and the air inside the airbag 1a of the cushion 1 is used at the place of use. The device can be easily used by inserting.

  Furthermore, according to the trunk extension muscle strength measuring apparatus of this embodiment, the controller 2 calculates the trunk extension muscle strength of the subject T obtained by processing the output signal of the pressure sensor 1c according to the given instruction. The measurement mode for outputting the value of the measurement result of the subject is compared with the value of the measurement result of the trunk extension muscle strength of the measurement subject T obtained by processing the output signal of the pressure sensor 1c and the preset training target value. When the measurement result value is equal to or higher than the training target value, it operates in one of two types of operation modes, which is a training mode that outputs that fact, so not only can you measure muscle strength by instructing the measurement mode By instructing the training mode and setting the training target value, even a person with a back can perform strength training so as to achieve the set value.

  Furthermore, according to the trunk extension muscle strength measuring device of this embodiment, the pressure-sensitive sensor 1c is supported by the pad 1b having a certain degree of hardness which is uniform in any part and received by the back of the person T to be measured. The pressure receiving surface provided with the pressure-sensitive sensor 1c of the cushion 1, which is output as an output signal so that the degree of pressure of each part of the pressure sensor 1c can be discriminated and obtained by processing the output signal of the pressure-sensitive sensor 1c. Since the distribution state of the degree of pressure received by the back of the person to be measured T is displayed on the screen by the display unit 2e as shown in FIG. 5, for example, the cushion receives the pressure depending on the distribution state of the pressure received by the pressure receiving surface of the cushion 1. Since it is possible to accurately know the site and height of the back part that is applying force to 1, it can be used for training for correcting the back of the circle. In addition, PP in FIG. 5 is a point which shows the part whose pressure is more than a predetermined value, and the part shown by S among the set of the points PP corresponds to the shoulder pad of the person T to be measured.

  Although the present invention has been described based on the illustrated examples, the present invention is not limited to the above-described examples, and can be appropriately changed within the scope of the claims. For example, the controller 2 can be used only in the measurement mode. (That is, only the measuring device is configured), the training mode only (that is, only the training machine is configured), or other modes of operation. Further, the cushion 1 and the controller 2 may be separably connected via a hose coupler and an electrical connector. Further, instead of the controller 2, an electric pump, a manual or foot pump, and a notebook personal computer or the like may be used in combination. Then, instead of the subject 1 sitting on the floor F with the back facing the wall W and pressing between the back and the wall W, the subject T sitting on the chair has the back and the chair. The person to be measured T who is in a supine position on the floor, bench, or the like may be pushed between the back and the floor, bench, or the like.

  Thus, according to the trunk stretch muscle strength measuring device of the present invention, when the person to be measured is a round person such as an elderly person, the cushion is elastically compressed and deformed corresponding to the circular back, and the feeling in the deformed state is felt. Since the pressure sensor detects the pressure due to the muscular force, the measurement can be performed without stretching the back, and the burden on the measurement subject can be reduced.
