KFORCE Sens® electrogoniometer in the evaluation of wrist range of motion in patients with carpal tunnel syndrome: validity and reliability

Abstract

This study aimed to test the validity and reliability of the KFORCE Sens® (electrogoniometer) in carpal tunnel syndrome (CTS) patients. Thirty-one volunteers (aged 32-60 years) diagnosed with unilateral CTS were included in this study. Each of the two raters evaluated the participants' wrist range of motion (ROMs) (flexion, extension, radial deviation, and ulnar deviation) twice, for a total of four times, using an electrogoniometer. In addition, wrist ROMs were evaluated once with a universal goniometer. According to the study findings, both the inter-rater and test-retest reliability of the electrogoniometer device in all ROMs of the wrist were excellent (ICC>0.80). In addition, the ROM values of the electrogoniometer device and the ROM values of the universal goniometer in the same joint were highly correlated (r>0.80, p<0.05). The electrogoniometer is a valid, reliable, and practical device for evaluating wrist ROMs in patients with CTS.
