effectiveness of tecar therapy on clinical symptoms and neurophysiological parameters of patients with carpal tunnel syndrome: a randomized clinical trial

Background: carpal tunnel syndrome (cts) is the most typical peripheral entrapment neuropathy. to date, various non-invasive methods have been used to manage cts. this study investigates the effectiveness of transfer energy capacitive and resistive (tecar), a new physical agent modality, on symptoms and neurophysiological parameters in patients with cts. methods: in this single-blind randomized clinical trial, 29 patients with mild or moderate cts were randomly assigned to two groups. group 1 received tecar therapy with a frequency of 500 hz and an intensity of 30 to 50%, 2 sessions/week, in addition to wrist splints and vitamin b supplements for 4 weeks. group 2 also received a wrist splint and vitamin b for 4 weeks without tecar therapy. the visual analog scale (vas), boston carpal tunnel questionnaire (bctq-sss and fss), as well as clinical and neurophysiological findings, were assessed before and 8 weeks after treatment. within and between-group comparisons were made after the intervention period. results: vas and the boston carpal tunnel questionnaire (fss and sss) showed significant changes. clinical cts tests and electrophysiological parameters did not show significant differences before and after the study. from a clinical perspective (pain relief and functional improvement), the tecar therapy group showed more definite changes. conclusions: tecar can be considered an effective non-invasive treatment for patients with mild to moderate cts.
