Description

Rehabilitation exercise aid

The present invention relates to a rehabilitation exercise assisting device, and more particularly to a rehabilitation exercise assisting device that can change a sport mode according to a user's condition to perform motion therapy suitable for the user.

Physical disability caused by diseases, trauma, sports injuries and post-operative weakness can improve physical self-care ability through physical therapy, and even restore or strengthen physical function. However, effective physical therapy must be diagnosed by a physician, and the rehabilitation therapist arranges the treatment based on the patient's personal condition. The most ideal method is a one-to-one humanized exercise therapy guide.

Rehabilitation therapists can also use the rehabilitation exercise machine to assist in the treatment process, which can reduce the workload of the rehabilitation therapist. The conventional rehabilitation exercise machine drives the mechanical device through the motor to pull the patient's limb for exercise treatment in a monotonous repetitive motion. However, the conventional rehabilitation exercise machine only provides a single and forced drive, and can not change the exercise mode according to the patient's condition, resulting in a reduction in the treatment effect, even when the patient is in an emergency (such as paralysis, hypotension, heart rate deviation) If it is not suitable for exercise, if the machine cannot be stopped immediately, it may cause the patient to suffer secondary damage.

In view of this, the conventional rehabilitation exercise machine does have the need to improve.
