Correlations of Tinel and Phalen Signs with Nerve Conduction Study Test Results in a Randomly Chosen Population of Patients with Carpal Tunnel Syndrome

The correlations between clinical signs and neurophysiological findings in CTS indicate that provocative tests, such as Phalen's and Tinel's, have limited diagnostic value, demonstrating only weak-to-moderate associations with neural conduction parameters. A positive Tinel's sign should be regarded mainly as a marker of severe or chronic sensory impairment, often accompanied by motor fibers involvement in advanced pathological stages, rather than as an indicator of motor damage alone. Nerve conduction studies remain essential for confirming CTS, assessing its severity, and guiding treatment decisions, including surgical qualification. The presented correlation of clinical and functional neurophysiological results in CTS diagnosis allows us not only to specify the source and severity of the pathology of the median nerve fibers but also may influence the personalization of physiotherapeutic and surgical treatments.
