Do Wrist Splints Help Tendonitis? Evidence-Based Guide
Do wrist splints help tendonitis?
The Quick Answer
**Yes—wrist splints effectively manage tendonitis** by limiting end-range motions that strain inflamed tendons while permitting pain-free movement. They reduce mechanical stress on tendon insertions during the inflammatory phase, allowing edema resolution. Splints should be worn during aggravating activities only (2–4 hours/day), not continuously—combined with rest, ice, and progressive loading exercises for optimal recovery.
Why We Ask This
Patients either avoid splints believing 'movement is always better' (aggravating inflammation through repetitive strain) or wear them continuously (causing tendon adhesions from lack of gliding motion)—both extremes delaying recovery versus strategic intermittent use aligned with tissue healing phases.
The Practical Science
Tendon healing requires balanced loading: complete rest causes adhesion formation; excessive loading perpetuates inflammation. Splints provide 'relative rest'—blocking harmful motions while permitting pain-free movement—reducing strain on tendon insertions by 40–60% during provocative activities without eliminating necessary gliding motion.
In Clinical Practice
A tennis player with wrist extensor tendonitis wears a rigid splint during matches and practice (blocking wrist extension during backhand strokes) but removes it for daily activities and performs eccentric loading exercises twice daily—resolving symptoms in 4 weeks versus 8+ weeks with continuous immobilization.
