INFLUENCE OF WRIST EXTENSION POSITION ON CARPEL TUNNEL SYNDROME PATIENTS USING MOUSE OF COMPUTER

Abstract

The purpose of study is to investigate the Influence of wrist extension position on carpel tunnel syndrome
patients during using mouse of computer subjects: ninety males and females mild CTS patients, their age
ranged from 40-60 years and their weight ranged from 65-95Kg, they were randomly divided into three
equal groups(G1,G2 &G3),G1 was instructed to use mouse of computer for six months with wrist
extension from 0-15 degree determined by digital goniometer, G2 was instructed to use mouse of
computer for six months with wrist extension from 15-30 degree determined by digital goniometer, G3
was instructed to use mouse of computer for six months with wrist extension from 30-45 degree
determined by digital goniometer. All patients assessed by Phalen’s sign test, Tinel’s sign test, Distal
Motor latency, Distal Sensory latency and digital goniometer pre and post the study. Results: the study
showed that there was slightly significant changes in CTS symptoms occurred in G3 only, however, a
little changes of CTS symptoms in both G1and G2 with less worsened for results for G1 regarding to
clinical and electrophysiological parameters. Conclusion: The degree of wrist extension position can
affect on progression of CTS symptoms in patients are using mouse of computer for six month and not
less than six hours daily. The more progression of CTS symptoms increase with increasing degree of
wrist extension
