Swan-neck deformity is a common symptom of rheumatoid arthritis affecting the fingers. It can be classified by hyperextension of the proximal interphalangeal (PIP) joint and flexion of the distal interphalangeal joint . Methods to correct hyperextension of the PIP joint range from surgery to splinting techniques . Silver ring splints (SRSs) were recently identified as a possible alternative to surgery and traditional thermoplastic splints because patient adherence was improved by their appearance . The objective of this study was to investigate whether the SRSs restrict PIP joint hyperextension during a fine dexterity task.
