Description

A training device for improving upper limb motor function in stroke patients

Technical Field

The utility model relates to the technical field of neurological rehabilitation training, and more specifically, to a training device for improving the upper limb motor function of stroke patients.

Background Art

Stroke has become the leading cause of death and disability among adults in my country. 50% to 85% of acute stroke patients and 50% of chronic stroke patients have upper limb dysfunction, which seriously affects the independence of patients' daily activities and social participation ability, and is one of the focuses of rehabilitation training.

The upper limbs of hemiplegic patients after stroke often show a flexor spasm pattern, among which the tension of the wrist flexors and finger flexors is significantly increased, which is difficult to solve through manual stretching by therapists, seriously affecting the recovery of patients' finger function; secondly, early patients have poor muscle strength and need therapists to assist patients in muscle strength training, but most patients have proprioceptive disorders and do not know how to activate the corresponding muscles, which increases the difficulty of training; thirdly, patients have common movements of the upper limbs and lack separate movements of the joints, especially the shoulder and elbow joints, which are the most difficult. For example, the elbow joint cannot be straightened during shoulder abduction, and the forearm cannot maintain a neutral position during shoulder flexion. The hands are often in a flexed grasping state during shoulder and elbow joint training. Long-term incorrect movement training patterns can inhibit the improvement of upper limb motor function and may also cause joint injuries and pain.

Rehabilitation training emphasizes active participation, multiple repetitions, simplified movements, and positive feedback. Although existing upper limb training equipment can meet the above requirements, it is poorly targeted at the main difficulties of upper limb motor dysfunction in stroke patients. The body compensation of patients during training is obvious, and the training effect is limited. In addition, the existing equipment is expensive, bulky, and complicated to operate. It is not suitable for continuation of ward and home rehabilitation training, and cannot meet the daily training needs of patients.
