WEAR DAY AND NIGHT - A functional solution for all-day support that is based on the latest advances in neurorehabilitation research. Wear the lightweight radial nerve palsy wrist splint during the day and at night while sleeping. WRIST EXTENSION STAY - The sewn-in plastic stay is covered in soft, padded foam for ultimate user comfort during extended wear. It holds your limp wrist up in extension (dorsiflexion), allowing the radial nerve to heal in a shortened position. REMOVABLE, ELASTIC FINGER LIFTS - The finger loops are slim and soft, emulating tendons to enhance the functionality of your fingers and hand and promote healing. Fully adjustable bases for customizable support. COMFORTABLE - Other dynamic splinting options following MCP arthroplasty or a radial nerve injury look like something straight out of a horror movie. This hand splint is non-intimidating, soft, comfortable, and easy to use. ONE SIZE FITS MOST - Use a soft/flexible tape measure to find the circumference around your wrist, in inches. Accommodates wrist circumferences up to 8.5 inches. Its unisex and universal design allows men and women to wear it on their right or left arm.
