A Wrist Hand Orthosis (WHO) is an umbrella term for supportive devices designed to stabilize, position, or immobilize the wrist and hand. These range from soft compression sleeves to rigid thermoplastic splints, depending on the severity of the condition.
General Specifications (2026)

Key Features & Adjustability
- Circumferential Compression: Most designs use multiple hook-and-loop (Velcro) straps (typically 3 to 7) to ensure even pressure and accommodate changes in swelling (edema).
- Anatomical Contouring: Designed to maintain a neutral position or a slight wrist extension (10°–35°) to balance forearm muscles and nerves.
- Integrated Thumb Support: Many WHOs include a thumb spica component to immobilize the CMC and MCP joints for conditions like De Quervain’s tenosynovitis.
- Hygiene & Care: Most models feature removable liners or use materials that can be easily cleaned with mild soap and water.
