Abstract: Objective To observe the effect of Arm Spasticity Inhibitor worn in rehabilitation training on patients with upper extremities spasticity and shoulder subluxation after stroke. Methods 80 stroke patients with flexor spasm in upper extremities complicated with subluxation of shoulder were divided into treatment group and control group equally. Both groups accepted routine medicine and rehabilitation, and the treatment group wore the Arm Spasticity Inhibitor developed ourselves during the rehabilitation training. Their acromio-humeral interval (AHI) was measured with the X- ray; and they were assessed with modified Ashworth Scale (MAS), range of motion of shoulder (ROM) and elbow before and 2 months after treatment. Results It improved more in the AHI, score of MAS and ROM in the treatment group than in the control group after treatment (P<0.001). Conclusion Wearing Arm Spasticity Inhibitor during rehabilitation training may release the spasticity of upper extremities and shoulder subluxation, and improve shoulder function in patients after stroke.
