Yes, elbow straps can help manage symptoms of tennis elbow.
Elbow straps, specifically inelastic, nonarticular, proximal forearm straps, can improve function during daily activities for patients with lateral epicondylitis.[1]
Counterforce bracing, a type of elbow strap, has shown to improve patient-rated pain, elbow function, and grip strength in the management of tennis elbow.[2]
Both counterforce and placebo braces demonstrated improvement in symptoms, suggesting some potential placebo effect or general support benefit.[2]
No significant safety concerns or side effects specifically associated with the use of elbow straps for tennis elbow were reported in the studies reviewed.
