Comparison of the efficacy of a neutral wrist splint and a wrist splint incorporating a lumbrical unit for the treatment of patients with carpal tunnel syndrome.

Background: Different types of splints have been used as a conservative intervention to improve symptoms in patients with Carpal tunnel syndrome (CTS). Although a number of studies have been undertaken to compare different splints, information and understanding of the influence of these interventions are lacking.

Objectives: The purpose of this study was to compare the effect of a classic thermoplastic wrist splint or a wrist splint with an additional metacarpophalangeal unit on pain, function, grip strength, and pinch strength in patients with mild-to-moderate carpal tunnel syndrome.
