Introduction: Carpal tunnel syndrome (CTS) is a common entrapment neuropathy caused by compression of median nerve beneath transverse carpal ligament. The aim of the study was to correlate clinical findings such as severity of symptoms and functional limitations with electrodiagnostic severity.The study was conducted in S.B.B.College of physiotherapy, Ahmedabad for 2 months. 30 subjects with CTS participated in this study.The outcome measures were (1) Carpal tunnel Syndrome Questionnaire( CTSQ). It has 2 sub scales, symptom severity scale and functional status scale and (2) nerve conduction studies (NCS) parameters such as Distal Motor Latency(DML), Distal Sensory Latency (DSL), Sensory Nerve Action Potential amplitude(SNAP), Compound Motor Action Potential(CMAP). NCS were performed for all participants who were referred for electrodiagnosis. The spearman correlation test was used to identify the relationship of electrodiagnostic findings with severity of symptoms and functional limitations.The results of the study showed a statistically significant moderate correlations between severity of symptoms and functional limitations with DML,DSL and SNAP amplitude, whereas no any significant correlation was found between CMAP amplitude with severity of symptoms and functional limitations. The results of the study concluded that, there is a moderate to weak relationship between electrodiagnostic findings with severity of symptoms and functional limitation.
