"Effectiveness of a Telerehabilitation Program Versus a Conventional Rehabilitation Program in Patients With Subacromial Pain"

Chronic subacromial pain represents a significant public health challenge and the most common musculoskeletal disorder after back and neck pain. Its etiology is multifactorial, causing substantial functional limitations, work disability, and a decrease in quality of life. The management of subacromial pain is primarily conducted through conservative interventions, with therapeutic exercise constituting the cornerstone of treatment to reduce joint pain, optimize shoulder function, and improve muscle strength.

Despite its efficacy, adherence to home exercise programs is often low due to a lack of supervision and motivation, which compromises long-term outcomes. While supervised, conventional in-person physical therapy improves adherence and functional outcomes, it presents significant logistical and economic barriers, such as travel costs, distance, and difficulty accommodating appointments within work schedules. This creates a gap in care, preventing many patients from receiving the necessary amount of therapy for optimal recovery.

Telerehabilitation, a remote healthcare delivery modality utilizing information and communication technologies, emerges as a promising solution to mitigate these barriers. Assisted digital therapy programs can be utilized to maximize treatment intensity, provide real-time biofeedback, and allow physical therapists to progressively adjust exercise complexity under remote guidance. This approach can potentially improve treatment adherence and reduce indirect costs for patients by eliminating travel needs and decreasing time off work.

Although current evidence provides compelling data regarding the efficacy of telerehabilitation, establishing its superiority over static home exercise programs, there is a lack of standardized protocols. Furthermore, a clear consensus has not been established regarding its non-inferiority to the conventional in-person model within a standard, non-pandemic clinical setting.

To address this gap, this study proposes a prospective, randomized, parallel-group, single-center, controlled non-inferiority clinical trial. The primary objective is to compare the change in shoulder function, as measured by the QuickDASH, at the end of a 12-week program between a telerehabilitation group and a conventional rehabilitation group. Secondary objectives include comparing changes in pain intensity (VAS) and range of motion (flexion, abduction, and external rotation), as well as evaluating treatment adherence, patient satisfaction, and long-term functional outcomes at 6 months. Answering this question will lay the groundwork for establishing a standardized, evidence-based telerehabilitation protocol as a highly accessible and sustainable care modality for patients with subacromial pain.
