BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described in more detail with reference to the drawings and the like.
FIG. 1 is a block diagram illustrating an embodiment of a walking exercise device according to the present invention, and FIG. 2 is a diagram illustrating a display example of a screen display unit of the walking exercise device according to the present embodiment.
The walking exercise device 10 of the present embodiment includes an operation unit 11, a lower limb exercise device 12 including a walking mechanism, a PC (personal computer) 15, a screen display unit 18, and the like.
[0010]
The operation unit 11 uses a screen of a touch panel, and can set an exercise pattern, a step length, and the like.
The lower limb exercising device 12 is a device capable of walking in a bipedal upright posture, and is provided with pressure sensors 13 and 14 for measuring the treading force of right and left feet. Each of the pressure sensors 13 and 14 can use a load cell or the like, and one pressure sensor is provided at the center of each of the left and right footrests.
The PC 15 includes a storage unit 16 that stores measurement data for a predetermined period of time, and a comparison operation unit 17 that performs a comparison operation on the measurement data for each stored measurement data.
[0011]
The display unit 18 is a part for displaying the measurement data and the comparison data on the screen. As shown in FIG. 2, as a display example of the exercise result, the number of steps a, the distance b, the average speed c, the calorie consumption d, the time In addition to displaying e, the balance f, which is a feature of the present embodiment, can be displayed.
[0012]
FIG. 3 is a flowchart illustrating the operation of the walking exercise device according to the present embodiment.
When the start switch of the operation unit 11 is turned on, the apparatus 10 starts (S100), and exercise speed and step length are set by the operation unit 11 while looking at the screen display unit 18 (S101).
[0013]
After the exercise is started (S102), the measurement is started after a certain time has elapsed (S103). The reason for starting the measurement after a certain time has elapsed is to eliminate the measurement error immediately after the start of the exercise and to stabilize the system. In addition to drifting at the center, there is also pedestrian wander.
[0014]
When an arbitrarily set measurement time (for example, 10 to 20 minutes) elapses, the measurement ends (S104). When the measurement is completed and the exercise is completed (S105), the measured data is stored in the storage unit 16 (S106).
[0015]
Then, based on the measurement data stored in the storage unit 16, the comparison calculation unit 17 calculates the center of gravity during walking from the difference between the treading forces of the left and right feet (S 107). Based on the calculation result, the center of gravity balance during walking is displayed (S108).
[0016]
4 to 7 are views showing the display of the locus of the center of gravity of the walking exercise apparatus according to the present embodiment.
Specifically, the comparison operation unit 17 calculates the locus of the center of gravity during walking as shown in FIG. 4, and the display unit 18 displays the locus of the balance of the center of gravity as shown in FIG.
At this time, the display unit 18 displays the balance of the center of gravity by a triangle T having the stepping point as a vertex.
In the display of the balance, in the case of normal walking, the triangle T appears symmetrically [FIG. 6 (a)], and in the case of right-sided walking, the right triangle TR appears largely [FIG. (B)], in the case of left-sided walking, the left triangle T-I appears large [FIG. 6 (c)].
It is also possible to display that the stride is short.
[0017]
Further, the comparison calculation unit 17 calculates the center-of-gravity trajectory during walking for each of the plurality of past measurement data stored in the storage unit 16, and the display unit 18 displays the past plural times (this time) as shown in FIG. , The trajectory of the center of gravity balance (triangles T1, T2, T3) can be displayed simultaneously.
As described above, when the data for the three times are compared, for example, it can be seen that, for example, the wobble was large at the beginning, and that the correction is gradually corrected as the time goes on. Based on this figure, talk with a doctor or other person who exercises the exercise and the patient who uses it, and give advice such as "Walk on the left side, so be careful." Can be.
[0018]
As described above, according to the present embodiment, the following effects can be obtained.
(1) The amount of movement of the center of gravity during walking is measured, and the state of movement of the center of gravity during walking is graphically displayed, so that intuitive understanding is possible. In the present embodiment, what is conventionally printed out and used can be displayed on the screen immediately after measurement.
(2) Since the trajectories of the center-of-gravity balance of a plurality of times in the past can be displayed at the same time, the transition of the measured value can be displayed and compared.
[0019]
(3) Although it is possible to maintain a bipedal upright posture, training and evaluation for fall prevention can be performed for those who are worried about walking and those who are frail elderly.
That is, the conventional walking exercise device is divided into a device for training and a device for evaluation / measurement, and there is no device for performing training and evaluation with one device. Further, the measuring device only displays data at the time of measurement, and there is no device having a function of comparing with a previous time and displaying a transition of a measured value in a certain period.
In the present embodiment, the walking exercise can be performed by one walking exercise apparatus, and the rehabilitation effect can be verified on the screen after the walking exercise.
[0020]
(Modified form)
Various modifications and changes are possible without being limited to the embodiment described above, and these are also within the equivalent scope of the present invention.
For example, by registering the user's "name" or the like as an ID and inputting an ID (including use of an ID card) at the time of use, a measured value can be recorded for each ID, and a chart function can be incorporated.
Alternatively, the user may be managed by ID, and past measured values may be freely taken out so that comparison and effect verification can be performed.
Furthermore, from the training (exercise) contents, the number of steps, exercise time, walking distance, average speed, calorie consumption, amount of body sway (balance), etc. are recorded, and the results are compared with past exercise results to verify the effectiveness of the training. It is also possible to do.
[0021]
【The invention's effect】
As described above, according to the present invention, since the center of gravity balance of the left and right feet of walking can be displayed on the walking exercise apparatus, the walking exercise can be performed, and the rehabilitation effect can be reduced based on the measurement data of the walking exercise. It became possible to verify.
