OBJECTIVES: To investigate how the severity levels revealed in a nerve conduction
study (NCS) affect the results of the Manual Tactile Test (MTT) for patients with
carpal tunnel syndrome (CTS), and to examine the relationships between the
results of the MTT and precision pinch performance. DESIGN: Case-control studies.
SETTING: Hospital and local community. PARTICIPANTS: Patients with CTS (N=70)
with 119 affected hands were studied. A control group matched by age, sex, and
hand dominance was also recruited. INTERVENTION: Not applicable. MAIN OUTCOME
MEASURES: CTS severity was determined based on NCS findings. The MTT, traditional
sensory tests, and precision pinch performance were used to examine the
functional sensory status of the hand from different perspectives. RESULTS: The
patients with CTS exhibited deterioration in all of the sensibility tests
(P<.001). The results showed that the MTT could classify subgroups of severity in
CTS (P<.001). A moderate correlation was found between the results of the MTT and
precision pinch performance (r=.526-.585, P<.001). Multiple linear regression
analysis showed that the MTT results were useful indicators for predicting
precision pinch performance and differentiating severity in subjects with CTS
(r(2)=.376 and .323, respectively). CONCLUSIONS: The findings indicate that the
MTT could be a valid and useful assessment for hand sensibility and prehensile
pinch performance in patients with CTS.
