Sleep and Functional Outcomes After Reverse Shoulder Arthroplasty

Condition(s) studied

Study summary

This prospective blinded study aims to investigate the relationship between objectively measured sleep parameters and patient-reported sleep and functional outcomes in patients undergoing reverse shoulder arthroplasty. Sleep will be assessed using MotionWatch 8, and outcomes will be correlated with validated clinical scores. This study is designed as a prospective, blinded clinical investigation conducted at a single tertiary referral center. Patients undergoing reverse shoulder arthroplasty for cuff arthropathy or glenohumeral osteoarthritis will be consecutively enrolled.

Objective sleep parameters will be collected using MotionWatch 8 one week prior to surgery in the patients' home environment. Functional and subjective sleep assessments will be performed preoperatively using validated scoring systems including ASES, Constant-Murley Score, VAS, SST, PSQI, and Jenkins Sleep Scale.

Postoperative follow-up will include reassessment of functional scores at 1, 3, and 6 months. At the 6-month follow-up, both subjective sleep assessments and objective sleep measurements will be repeated.

The primary objective is to evaluate the correlation between objective sleep parameters and ASES and PSQI scores.

Eligibility

Primary outcome measure(s)

• Correlation Between Objective Sleep Parameters and Clinical Outcome Scores — 6 months postoperatively
  The primary outcome is the strength of association between objective sleep parameters measured by actigraphy (MotionWatch 8), including total sleep time, sleep efficiency, sleep latency, and nocturnal activity, and patient-reported outcome measures, specifically the American Shoulder and Elbow Surgeons (ASES) score and Pittsburgh Sleep Quality Index (PSQI).
