The effectiveness of splinting and surgery on sleep disturbance in carpal tunnel syndrome

Abstract

This controlled prospective study assessed the effectiveness of night splinting compared with non-splinting and surgery for severity of insomnia in patients with carpal tunnel syndrome. Sleep characteristics were observed for several days without a brace, with a brace and after surgery. The sleep measurements included the use of an actigraph worn on the wrist during night, a ‘sleep log’ that conveyed subjective impressions as to how the patient had slept and a short insomnia instrument, the Insomnia Severity Index. The Insomnia Severity Index scores showed that a night splint significantly improved insomnia symptoms compared with no splinting, and surgery significantly improved insomnia symptoms compared with splinting. The sleep log scores showed that the sleep quality and the number of awakenings when a splint was not worn were significantly different from the scores with the splint and the scores after surgery but showed no differences between splint and surgery. The actigraph did not show any significant differences between the treatment methods. Level of evidence: III
