Description

  The present invention relates to a training machine for a wheelchair user who can prevent a disuse syndrome due to lack of lower limb exercises for a person who lives in a wheelchair.

In general, the number of muscle fibers starts to decrease from the 30s, and becomes less than half at 80s.
The decrease in muscle strength due to aging is particularly prominent in the lower limbs, and many elderly people use wheelchairs early on to prevent fractures due to falls.
In addition, there are many people who have quadriplegia or paraplegia due to causes such as traffic accidents.
These people also use wheelchairs for living, but if the frequency of exercising the lower limbs becomes extremely low, it will cause various secondary disorders called disuse syndrome.
In order to prevent these disuse syndromes, all patients who use wheelchairs are encouraged to stand up and exercise such as walking if possible.
However, this walking movement requires a dedicated walking path with parallel bars and the like, and always requires the assistance of a caregiver to assist in standing up and ensuring safety during walking.
For this reason, wheelchair users had to go to hospital rehabilitation facilities regularly.
However, in cold snowfall areas such as Tohoku, it is difficult to go out in a wheelchair in the winter, and there is a need for a device that can easily perform rehabilitation exercises at home.
In addition, although it is not a rehabilitation apparatus, the gymnastics which exercise | move exercise | movement of a leg part, especially a calf part, abdominal muscle, etc. by repeating lying up using an auxiliary string is known (patent document 1). ).
