Exploring pain modulation in shoulder arthroplasty patients

Endogenous Pain Modulation in Patients With Shoulder Arthroplasty for Osteoarthritis

Reinier Haga Orthopedisch Centrum · NCT05861960

This study is trying to see how pain responses change in patients with shoulder arthritis after they have surgery, and how their thoughts and coping methods might affect their pain after the operation.

What this trial studies

This observational study aims to investigate the presence of central sensitization and abnormal conditioned pain modulation (CPM) responses in patients scheduled for total shoulder arthroplasty (TSA) due to osteoarthritis. It will assess whether these pain modulation measures change following surgery and explore the role of psychological factors and coping strategies in pain outcomes. The study focuses on a subgroup of patients to better understand the mechanisms behind persistent postoperative pain.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older who are scheduled for primary total shoulder arthroplasty or reversed shoulder arthroplasty due to primary shoulder osteoarthritis.

Not a fit: Patients with chronic pain disorders other than osteoarthritis or those on certain medications like anti-depressants may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved pain management strategies for patients undergoing shoulder arthroplasty.

How similar studies have performed: While studies have explored pain modulation in other types of arthroplasty, this specific focus on shoulder arthroplasty is relatively novel.
