The effect of a forearm hand splint compared with an elbow band as a treatment for lateral epicondylitis

The aim of the present study was to compare the effect of a new prefabricated Thämert forearm hand splint with the effect of a simple elbow band as a treatment for lateral epicondylitis. Forty-three (43) patients that met the inclusion criteria were randomly assigned to the elbow band group and the splint group. They wore the orthotic devices for 6 weeks. Outcome measures were obtained at baseline and directly after the intervention. These outcome measures were maximal grip strength on the involved side with a pain scale from 1 to 10 to determine the extent of pain during gripping, and the Patient-Rated Forearm Evaluation Questionnaire (PRFEQ). Analysis of variances with repeated measures, a Mann Whitney test and multiple linear regression analysis were used to compare the two groups. Main effect for time was significant for maximal grip strength and sum scores on the PRFEQ, but no differences between groups were found, even when a distinction between acute and chronic symptoms was made. Change in pain score during gripping did not differ significantly between the groups. A multiple linear regression analysis showed that the use of the splint did not significantly contribute to the prediction of change in maximal grip strength and in overall PRFEQ. The conclusion is that the forearm hand splint is not more effective than the elbow band as a treatment for lateral epicondylitis.
