Continuous low-level heat wrap therapy is effective for treating wrist pain

Area of Science:

• Orthopedics
• Pain Management
• Physical Therapy

Background:

• Wrist pain from conditions like strain/sprain, tendinosis, osteoarthritis, and carpal tunnel syndrome significantly impacts daily function.
• Non-pharmacological treatments are sought to manage wrist pain and improve quality of life.

Purpose of the Study:

• To assess the efficacy of continuous low-level heat wrap therapy in treating diverse wrist pain etiologies.
• To compare heat wrap therapy against placebo and other interventions for pain relief and functional improvement.

Main Methods:

• A prospective, randomized, single-blind, placebo-controlled, multicenter trial involving 93 patients with moderate to severe wrist pain.
• Patients were stratified into groups receiving heat wraps, oral placebo, oral acetaminophen, or unheated wraps.
• Outcomes measured included pain relief, joint stiffness, grip strength, and patient-reported disability (PRWE), with specific scales for CTS.

Main Results:

• Heat wrap therapy significantly improved pain relief and grip strength in patients with strain/sprain, tendinosis, and osteoarthritis compared to oral placebo.
• For carpal tunnel syndrome patients, heat wraps led to significant reductions in pain, stiffness, symptom severity, and improved functional status and grip strength.
• Benefits for CTS patients extended through the follow-up period.

Conclusions:

• Continuous low-level heat wrap therapy is an effective treatment for common causes of wrist pain and functional impairment.
• Heat wrap therapy offers a viable non-pharmacological option for managing wrist pain, particularly for carpal tunnel syndrome.
