To do. At this time, as shown in FIG. 2, the support rod 3b (3a) on the side where the cane 7 is used is arranged so as to be turned over to the outside so as not to get in the way.

In this case, the computing device 10 computes the force of the support rod 3a (3b) grasped by the left hand (right hand) and the force applied to the cane 7. In addition, the left foot 8a of the standing practitioner 1 is on the floor reaction force detection device 5a, and the right foot 8b is the floor reaction force detection device 5a.
When standing up so as to be positioned on b, the calculation device 10 calculates the force and position applied to the lower limbs.

At this time, the synchronous arithmetic processing unit 12 causes
The vector direction can be calculated from the force applied to the upper limbs and the component force in each direction, and the vector direction can be calculated from the force applied to the lower limbs and the component force in each direction. Further, the synchronous arithmetic processing unit 12 allows the left foot 8a

With the passage of time, the upper limb loads 31a, 32
The waveforms of a, the floor reaction forces 33a and 33b, and the cane load 34b each progress to the right, and when data collection is completed due to the lapse of a prescribed time, the waveforms and the like automatically stop. If you want to stop during the measurement, click the stop key (not shown).

For example, if 100% of the body weight cannot be applied to the lower limbs immediately after the operation, the body weight should be gradually increased to 10%, 30%, etc. by the instruction of the physiotherapist who supports the standing exercise. Do standing exercises, or if you don't put more weight on your weight than the specified value, such as 20%. In this case, the value of the lower limb load at that moment can be monitored by looking at the display device 13. Even if the sense of weight of the lower limbs on the operating side is paralyzed and the awareness of the standing practitioner is insufficient, standing up while looking at this display screen 13 allows you to see how the weight is applied visually. The effect is that it can be confirmed by a physical therapist and can be constantly monitored by a physical therapist.

For the visually impaired standing practitioner,
When the lower limb load exceeds a preset value such as 10% or 30% in advance, a beeping sound is emitted from the speaker 15,
It is possible to output a voice that the lower limb load exceeds the set value. Or, if the specified value such as 20% is not exceeded, a warning sound is emitted, guidance is given to apply sufficient weight above the specified value, or a voice indicating that the application of weight is insufficient is output. You can As a result, even a visually impaired standing practitioner can engage in correct standing training while listening to audio and the like.

Further, it is possible to quantitatively grasp how to apply the force at the time of standing up from the waveform and bar graph in the case of standing up motion from a wheelchair or the like. The correct standing motion is required to stand up without pulling the supporting rod 3 as much as possible and without depending on the supporting rod 3 or the cane 7 as much as possible. That is, bar graphs 21, 22, 2 as much as possible
4 and the waveforms 31, 32 and 34 are desired to be small.

As described above, in the standing posture exerciser 2, the force of the upper limb exerted on the support rod of the standing trainee 1, the force of the lower limb exerted on the floor reaction force detecting devices 5a and 5b, and the walking force detecting device 7a. ,
The force of the cane exerted on 7b (cane load) can be calculated, and bar graph display, waveform display, and vector display can be performed. Then, by storing them and comparing them with past data, it is possible to quantitatively grasp the progress of the practice, the degree of recovery, and the like. In addition, the difference in left and right lower limb load balance can be calculated, displayed, and stored in the same manner. By effectively utilizing these data, doctors and physiotherapists can effectively promote standing exercises for patients. As a result, it becomes possible to practice in a short period of time.

Further, by providing a sound output device for outputting the synchronous calculation result of the synchronous calculation processing device as a sound, not only the practice result can be visually recognized but also the practice can be performed while listening to the ear. Even free people can practice while checking the results of the practice. Further, since the standing exerciser of each embodiment has a very small plane area, it is suitable for standing up exercises by moving around the bed, and can be applied to a rehabilitation facility having a small area.
