Description

Rehabilitation treatment device

The invention relates to a rehabilitation treatment device, in particular to a rehabilitation treatment device which is not single direction, simple in structure and low in maintenance cost.

According to the World Health Organization (WHO), stroke is the third leading cause of death in developed countries. About 15 million people have a stroke each year, and one third of them die and three more. One surviving patient is permanently paralyzed. The damage caused by stroke is quite extensive, such as language ability, cognitive ability, sensory ability, movement ability, etc., and the damage to the brain. Motor Impairment is one of the clinical symptoms of stroke, affecting patients' daily life. For most patients, recovery of the upper limbs is more difficult than recovery of the lower limbs. Most of the self-care ability of daily life depends on the ability of the upper limbs to move, so upper limb rehabilitation is relatively important.

Common treatments for upper limb rehabilitation such as task-oriented motor training, constraint-induced movement therapy (CIMT), mirror therapy, bilateral movement training Etc., each has its own theoretical claims, and also has a wide range of clinical applications. From the results of Mary et al., it can be seen that bilateral arm training is more effective than unilateral for the proximal function of moderately impaired patients, and can improve the connection function of the left and right hemispheres of the brain, which is very important for the coordination of the two hands.

Although most patients can get exercise capacity through rehabilitation, there are still 30-60% of patients unable to use their limbs. Obviously, there is room for improvement in rehabilitation efficiency. In recent years, new therapeutic technologies such as machine-assisted motion therapy and even virtual reality have been applied to clinical treatment in an attempt to improve the quality of upper limb rehabilitation. Mechanical assisted motion therapy has been developed for more than ten years, clinically proven machines such as MIT-MANUS, BI-MANU-TRACK, BATRAC, MIME, etc., which focus on the rehabilitation site, movement direction, patient status, complex Health treatments are different. In clinical studies, mechanically assisted rehabilitation has been shown to be more effective than traditional therapy.

In the double-sided rehabilitation machine mentioned above, the forearm and wrist rehabilitation is BA-MANU-TRACK; for the shoulder and elbow rehabilitation is BACTRAC and MIME. BACTRAC has only one direction of action; MIME has a high degree of freedom but a complicated machine, and it is expensive in terms of operation training or maintenance.

Regarding the design requirements of mechanical rehabilitation machines, Annick et al.'s research proposes a design policy for stroke upper limb rehabilitation machines, which is divided into three parts: treatment methods, motivation, and performance feedback. On the other hand, according to a survey of 233 therapists, the most suitable conditions for rehabilitation machines required by the therapist are: they can do different hand movements, can sit and use, give users feedback, and There are virtual activities related to daily life, can be used at home, have resistance adjustment, and the price is below US$600. In addition, for stroke patients, since the shoulder and elbow movements are almost always required for daily life movements, the recovery of the proximal function of the hand is very important.

In terms of the usability of rehabilitation equipment, research indicates that the relationship between the machine and the user is often neglected during the development of rehabilitation equipment. Although many researchers have developed upper limb rehabilitation machines, they are less likely to go to commodities. The reason for the low market acceptance may be that the amount is too high, and the safety or usability is low. Moreover, as far as the researchers are concerned, the current general research is more effective than the clinical efficacy of the machine, and there is no discussion on the usability of the rehabilitation machine.

Therefore, how to design a rehabilitation treatment device that is not single direction, simple in structure, and low in maintenance cost has become the goal of related manufacturers and related R&D personnel.

The present inventors have actively pursued development in view of the fact that the conventional rehabilitation device has a single direction, a complicated machine, a maintenance time or a relatively expensive cost, and is expected to improve the above-mentioned shortcomings. Experiments and efforts have finally developed the present invention.

It is an object of the present invention to provide a rehabilitation treatment device that is not unidirectional, has a simple structure, and has low maintenance costs.

In order to achieve the above object, the rehabilitation treatment device of the present invention comprises a base, two slide rails, a plurality of pulleys, two belts, a second-hand handle, two bearings and a motor.

The slide rails are separately disposed on the left and right portions of the base. The pulleys are discretely disposed within the rails. The belts are each sleeved on the pulleys and the positions correspond to the rails. The handles are each movably inserted into one of the slide rails on the left and right sides, and are each fixed at an outer edge of one of the belts.

The bearings are each connected to one of the pulleys at one end of the shaft. The motor is powered to rotate one of the pulleys that are coupled to one end of the shaft of the bearings.

Through the above structure, the present invention has the characteristics of non-unidirectional direction, simple structure, and low maintenance cost.
