Evaluation of Joint Position Sense with Two Different Electrogoniometers in Carpal Tunnel Syndrome

Carpal tunnel syndrome causes changes hand proprioception but there are a limited number of studies on joint position sense in patients with CTS. The aim of the study was to investigate the validity and reliability of the ® KForce Sens for the evaluation of wrist joint position sense in individuals with CTS. Wrist joint position sense ® ® ® was assessed with KForce Sens and Baseline electrogoniometer. The validity and reliability of the KForce Sens for wrist position sense evaluation were investigated by comparing the two data sets. The study was conducted in 35 patients (29 females, 6 males) with CTS and 35 healthy individuals (29 females, 6 males). In test-retest ® measurements of the KForce Sens , a significant correlation was found in 60° flexion (ICC=0.730), 30° extension (ICC=0.904), 60° extension (ICC=0.849), 15° ulnar deviation (ICC=0.834) and 10° radial deviation (ICC=0.952). ® ® significant correlation was found between KForce Sens and Baseline electrogoniometer in 30° flexion, 60° flexion, 30° extension, 60° extension, 15° ulnar deviation and 10° radial deviation (p<0.05). The difference in joint position sense was significant in 30° flexion (p<0.001), 60° flexion (p=0.023), 30° extension (p=0.003), 60° extension (p=0.037) compared to the healthy controls. There was no significant difference in ulnar deviation and ® 10° radial deviation movements (p>0.05). The KForce Sens device is a valid and reliable tool for the assessment of wrist joint position sense in patients with CTS. Even if the severity of CTS was mild, joint position sense was lower than that of healthy controls.
