Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an exercise +111 exercise device capable of displaying the duration at the limit of movement during anti-load exercise.

[Conventional technology]

It is desirable that the exercise training device used for functional recovery training for physically disabled people and post-surgical patients be able to change the exercise load settings according to the physical strength of the practitioner. The training device 1 is used for strength training of the femoral rotator muscle, and the trainee sits on a chair 2I and places his/her ankles on the pad 3A at the end of the drive arm 3, which is pivotally supported on the side of the chair 2. harm.

This exercise training device 1, which performs an exercise of kicking up the shins, allows the exercise load to be adjusted by changing the weight of a detachable load 4a attached to the end of a driven arm 4 coaxially supported with a drive arm 3. It has become.

[Problem that the invention seeks to solve]

When the above-mentioned conventional exercise training device 1 is used for training to overcome functional disorders of the knee joint related to the exercise of the femoral rotator muscle or this muscle, the number of knee joint extension exercises cumulatively displayed on the meter is calculated as a load. Exercises are only performed that mainly focus on strengthening muscle strength, increasing and increasing muscle strength, and exercise evaluation is performed from the perspective of how much sustained tension can be maintained near the boundary between the range of motion and the limit range of the knee joint. This is left to the subjective judgment of accompanying caregivers, etc., and since it is not possible for trainees to mechanically detect this type of motor evaluation and improve their biofeed, recovery from functional impairment may be slow. There was a problem.

[Means for solving problems]

This invention solves the above problems.

A loading device that applies load to muscle movements centered on joints,
When you exercise your limbs against the load of this loading device,
A range of motion sensor outputs a signal during periods when the limb is moving beyond a preset limit range, and the output of this range of motion sensor indicates evidence.

The gist of the device is that the device is constructed of a display means that displays a message to that effect when a predetermined period of time has been exceeded.

[Effect]

This invention is a muscle anti-load exercise (in this case, when a limb moves beyond a certain limit range and the time for exceeding the limit range exceeds a preset set time, the This enables effective functional recovery exercises using biofeedback.

〔Example〕

Hereinafter, embodiments of the present invention will be described with reference to FIG. FIG. 1 is a schematic diagram showing an embodiment of the exercise machine of the present invention.

Components in FIG. 1 that are the same as those in FIG. 2 are given the same reference numerals.

In the fifth construction drawing, the exercise v11 exercise device 111 is a device for strengthening the muscle strength of the quadriceps femoris, and includes an angle sensor 12 that detects the rotation angle of the drive arm 3, and an output of this angle sensor 12 that is a comparator circuit 13 that detects that the predetermined value has been exceeded; a delay circuit 14 that is triggered by the output I of the comparator circuit 13 and outputs a high-level signal for a certain period of time; circuit 13
an AND gate circuit 15 connected to the signal input terminal;
and a display device 16 connected to the output terminal of this AND gate circuit 15.

In this embodiment, the angle sensor 12 and the comparison circuit 13 constitute a range of motion sensor, and the delay circuit 14. AND gate circuit I
5 and the display device L6 constitute display means.

The display device [16 is displayed when the trainee extends the knee.

If the knee joint is able to stretch against the load for more than a certain angle, which exceeds a time τ, an audio-visual display is performed using light, sound, etc., in other words, the knee joint resists the load. When it extends beyond a certain angle, the output of the comparison circuit 13 becomes high level due to the output of the angle sensor 12. the result,
The delay circuit 14 is triggered by the high level output of the comparison circuit 13.

After the delay circuit 14 is triggered, if the knee joint has rotated by the angle Ic or more beyond the delay time τ, the high-level output of the delay circuit 14 and the high-level output of the comparison circuit 13 cause the AND The gate circuit 15 is closed, and the output of the AND gate circuit 15 activates the 1 display device [6.

In this way, the above-mentioned exercise-11 training device 11 has a thigh Vf.
When the knee joint moves beyond a certain limit range during anti-load exercise of the J head muscle, and the time for exceeding the limit range exceeds a preset time τ.

Display that effect.Since m = 1, functional recovery training for patients with functional disorders, etc., set goals for linked training based on the range of motion of the knee joint and the duration of anti-load tension. be able to. Therefore, it is not only possible to increase muscle strength through training that balances the load and muscle strength and maintains a state of tension for a certain period of time, but also when training to improve functional impairment due to damage to the calamus. Even if information cannot be obtained from the divine path system, effective functional IgJ retraining is possible through biofeedback f, which visually and visually assesses the display on the display device 16.

In the above embodiment, by variably setting the reference value of the comparison circuit j3, it is possible to change the boundary setting between the range of motion and the limit range, and by variably setting the delay time τ in the delay circuit 14f. You can change the target duration of tension.

The exercise training device of this invention is not only useful for strengthening quadriceps muscles, but also for other anti-load exercises performed against the load of springs, weights, etc. It can also be applied to bending and stretching movements, bending and stretching movements of the lower limbs, internal and external rotation movements of the hip joints, plantar dorsiflexion movements of the ankle joints, etc.

〔Effect of the invention〕

As explained above, according to the present invention, when a limb moves beyond a certain limit range during muscle anti-load exercise, the time for exceeding the limit range exceeds a preset set time. (1) In functional recovery I11 training for patients with functional disorders, goals for exercise training are set based on range of motion of joints and duration of anti-load tension. Therefore, it is not only possible to strengthen muscle strength through exercise training that balances C load and muscle strength and maintains a state of tension for a certain period of time, but also to improve functional disorders caused by damage to the nervous system1. Even if information from the nervous system cannot be obtained, as in the case of practicing III,
Biofeedback, which allows the user to understand the display on the display means through audio and visual means, has excellent effects such as enabling effective functional recovery exercises.
