OBJECTIVE. Our objective was to review the evidence regarding the effectiveness of splinting for carpometacarpal osteoarthritis. METHODS. A systematic review was conducted. Clinical considerations, occupational therapy exemplars, and further research questions were identified. RESULTS. There was fair evidence for the effectiveness of splinting to relieve pain and improve function. There was no clear evidence of the superiority of one type of splint over another for pain relief, comfort, or function. Patient preference regarding type of splint varied. CONCLUSIONS. Research to date indicates that splinting may help relieve pain in persons with carpometacarpal osteoarthritis. Further investigation is recommended using controlled methodology, more thorough reporting of outcomes, and tracking of analgesic use.

Occupational therapists are expanding their use of custom and commercial soft splints fabricated from neoprene (poly-chloroprene), but little has been written regarding dermatological issues associated with this material. Skin contact with neoprene poses two dermatological risks: allergic contact dermatitis (ACD) and miliaria rubra (i.e., prickly heat). Allergic reaction to neoprene is generally ascribed to the accelerants used to manufacture the man-made rubber, specifically thiourea compounds and mercaptobenzothiazole (MET). Symptoms of neoprene-related ACD include itching, skin eruptions, swelling, and hemorrhages into the skin. Miliaria rubra creates small, red, elevated, inflammatory papules and a tingling, burning sensation. Although neoprene hypersensitivity is rare, its incidence may grow as neoprene becomes a more commonly used material. It is recommended that therapists screen patients for a history of dermatological reactions to neoprene or other materials containing thiourea compounds or MBT and educate patients to discontinue splint use if dermatological symptoms develop. Therapists are also encouraged to notify splint manufacturers regarding all ACD reactions.
