A dynamic cockup finger extension splint is an orthotic device that uses a rigid support frame for the wrist and a flexible tension system to promote functional movement of the fingers, aiding rehabilitation from nerve injuries, stroke, or post-surgical stiffness.
General Specifications
- Intended Use: Designed for post-surgical support, physiotherapy after extensor tendon repair, and managing conditions like radial nerve palsy (wrist drop), stroke recovery, and cerebral palsy.
- Action: Provides both a rigid component to support the wrist in an extended (dorsiflexion) position and a dynamic component that helps exercise and restore muscle tone and mobility to the fingers.
- Target User: Primarily designed for adults, with many products offering universal sizes and ambidextrous designs (often achieved by switching the thumb support mechanism).
Key Features
- Adjustable Tension: The spring or rubber band system allows for the tension force to be adjusted or customized based on the user’s specific rehabilitation needs and comfort levels.
- Finger Holders: Includes specific holders, often soft loops or padded rings, for each finger to ensure proper positioning and movement assistance, though some users report fingers may slip.
- Wrist Positioning: The static component holds the wrist in a functional, extended position, allowing the radial nerve to heal in a shortened position (in cases of nerve palsy).
- Lightweight Design: The splint is designed to be lightweight (typically around 150g – 300g) to prevent fatigue and encourage patient compliance.
