Neuropathic pain, catastrophizing, and therapy adherence in shoulder impingement
The Relationship Between Neuropathic Pain, Pain Catastrophizing, and Adherence-Related Behavior in Subacromial Impingement Syndrome
This study will see if people with subacromial impingement who have neuropathic pain also report more pain catastrophizing and lower adherence during a standard physical therapy program.

What this trial studies
This prospective observational cohort follows patients with unilateral subacromial impingement scheduled for a 10-session outpatient physical therapy program. Participants complete validated scales for neuropathic pain features, pain catastrophizing, and adherence-related behavior at baseline and after completing therapy. The study excludes patients with diabetes, peripheral neuropathy, recent injections or surgery, complete rotator cuff tears, calcific tendinitis, frozen shoulder, pregnancy, or cognitive impairment. Findings aim to identify links between pain characteristics, psychological factors, and adherence to help tailor rehabilitation strategies.
Who should consider this trial
Good fit: Adults with unilateral subacromial impingement lasting at least three months who are about to start a 10-session outpatient physical therapy program and can give informed consent.
Not a fit: Patients with diabetes, generalized neuropathy, complete rotator cuff tears, recent shoulder injections or therapy, pregnancy, cognitive impairment, or other excluded conditions will not be included and therefore are unlikely to benefit directly.
Why it matters
Potential benefit: If successful, results could help clinicians identify patients who may need additional pain-focused or psychological support to improve rehabilitation outcomes.
How similar studies have performed: Prior musculoskeletal research has linked neuropathic pain signs and catastrophizing to worse outcomes, but combining these factors with adherence behavior specifically in subacromial impingement is relatively underexplored.
