Abstract/OtherAbstract:
Background:Based on the literature, patients with carpal tunnel syndrome are suggested to wear a custom-made wrist orthosis immobilizing the wrist in a neutral position. Many prefabricated orthoses are available on the market, but the majority of those do not assure neutral wrist position.Objectives:We hypothesized that the use of orthosis affects grip strength in persons with carpal tunnel syndrome in a way that supports preference for custom-made orthoses with neutral wrist position over prefabricated orthoses.Study design:Experimental.Methods:Comparisons of grip strength for three types of grips (cylindrical, lateral, and pinch) were made across orthosis types (custom-made, prefabricated with wrist in 20° of flexion, and none) on the affected side immediately after fitting, as well as between affected side without orthosis and nonaffected side.Results:Orthosis type did not significantly affect grip strength (p = 0.661). Cylindrical grip was by far the strongest, followed by lateral and pinch grips (p < 0.050). The grips of the affected side were weaker than those of the nonaffected side (p = 0.002).Conclusions:In persons with carpal tunnel syndrome, neither prefabricated orthoses with 20° wrist extension nor custom-made wrist orthoses with neutral wrist position influenced grip strength of the affected hand. Compared to the nonaffected side, the grips of the affected side were weaker.Clinical relevanceThe findings from this study can be used to guide application of orthoses to patients with carpal tunnel syndrome.
