This study compared the biomechanical effectiveness of a placebo “splint” (sham treatment), a static neutral wrist splint and a newly designed dynamic wrist splint in 7 individuals with carpal tunnel syndrome (CTS). A single-subject ABCACB multiple treatment design was used over 6 weeks. Eight outcome variables were monitored (including sensory, motor, pain and functional measures). Participants demonstrated beneficial effects of both splinting treatments in symptom reduction and hand function restoration. Dynamic wrist splint use, furthermore, was accompanied by better therapeutic outcomes and compliance with splint wearing compared to the static wrist splint. The findings suggest that the newly designed dynamic splint might provide hand therapists with an alternate choice of splinting in cases of CTS where conservative treatment is sought.
