What Does Wearing a Wrist Splint Do? Clinical Benefits Explained
What does wearing a wrist splint do?
The Quick Answer
A wrist splint **immobilizes the wrist joint** in a neutral position to reduce strain on tendons, ligaments, and nerves—particularly the median nerve in carpal tunnel syndrome. It prevents harmful flexion/extension during sleep or activity, decreases inflammation through joint unloading, and provides proprioceptive feedback that reminds users to avoid positions aggravating their condition.
Why We Ask This
Patients experience worsening nocturnal numbness or daytime pain flare-ups from unconscious wrist positioning during sleep or repetitive tasks, not realizing that brief periods of extreme flexion significantly increase carpal tunnel pressure and delay healing.
The Practical Science
Splints maintain the wrist at 0–15° extension where carpal tunnel pressure is minimized (under 30mmHg). Studies show neutral positioning reduces median nerve compression by 40% versus flexed positions, allowing edema resolution and nerve recovery during critical rest periods.
In Clinical Practice
A dental hygienist with carpal tunnel wears a rigid splint nightly to prevent unconscious wrist flexion during sleep—eliminating morning numbness within 2 weeks—while using a flexible support during work hours to maintain neutral alignment during instrument handling.
