Research and Clinical Validation of a Wearable Device-Based Remote Rehabilitation System for Postoperative Rotator Cuff Injury

Research and Clinical Validation of a Wearable Device-Based Remote Rehabilitation System for Postoperative Rotator Cuff Injury

This study included patients who underwent their first shoulder rotator cuff surgery at Peking University Third Hospital, diagnosed with small to medium rotator cuff tears based on MRI results. Participants were randomly divided into an online wearable device training group and an offline traditional rehabilitation group, with 36 individuals in each group. Before testing began, patients were ensured to participate voluntarily and had signed informed consent forms.

In this randomized controlled clinical study, patients with unilateral rotator cuff tears were included. Starting from the fifth week after surgery, they were randomly assigned to either an online wearable device training group or an offline traditional rehabilitation group, with analyses conducted through functional tests and assessments. The study investigated the impact of wearable device rehabilitation on functional recovery in patients with rotator cuff tears and compared it with offline traditional rehabilitation to verify its efficacy.

Inclusion Criteria:

• Age ≥18 years;
• First-time rotator cuff injury surgery and received surgical treatment at Peking University Third Hospital;
• MRI shows a tear with a maximum diameter <3 cm, confirmed by at least three musculoskeletal rehabilitation radiologists;
• Possess a mobile device with internet access (e.g., smartphone or tablet) capable of using mobile applications;
• Able to complete the planned study and follow-ups within 6 months after discharge;
• No visual, hearing, cognitive, or communication impairments;
• Able to provide informed and valid consent to participate in the study.

Exclusion Criteria:

• Presence of serious cardiovascular or cerebrovascular diseases, or cervical spondylosis with nerve damage;
• Presence of cognitive impairment or vision problems;
• Stroke, rheumatic disease, neurological disorders, or diseases limiting overall physical function or cardiopulmonary function within the past 2 years;
• No prior history of shoulder joint injury, and having undergone other surgeries within the past 6 months;
• Patients who cannot complete the entire cycle or drop out midway;
• Presence of serious postoperative complications, such as wound infection, venous thromboembolism, etc.
