Comparison of 4 weeks of cupping and Kinesio-taping on clinical and ultrasound outcomes of carpal tunnel syndrome during pregnancy

Abstract

ObjectiveTo explore effect of cupping and Kinesio-taping techniques on clinical and ultrasound outcomes of carpal tunnel syndrome (CTS) during pregnancy. MethodsThirty pregnant women suffering from CTS were randomly assigned into Kinesio-taping (n = 15) and cupping (n = 15) groups. In Kinesio-taping group, individuals underwent Kinesio-taping for three days, one day with no treatment, and three days with Kinesio-taping, continuing this procedure for four weeks. In cupping group, cupping was moved for 5 min with pressure of 50 mm-Hg on the carpal tunnel area. This procedure continued longitudinally in forearm area for 2 min. The therapeutic intervention of cupping group continued with eight sessions, two days a week for 4 weeks. Ultrasound outcomes including median nerve cross-sectional area through ultrasonography, and clinical outcomes including pain through visual analog scale and severity of symptoms and functional status through Boston questionnaire were measured in both groups before and after therapeutic program. ResultsIn both groups, a significant reduction was observed in all variables after treatment compared to pre-treatment (P < 0.001). In inter-group comparison, a significant improvement was found in outcomes of Boston questionnaire and ultrasound results about median nerve cross-sectional area at pisiform and hook of hamate in cupping group compared to Kinesio-taping at end of four weeks (P < 0.001). ConclusionBoth cupping and Kinesio-taping improved clinical and ultrasound outcomes of CTS. However, efficacy of cupping compared to Kinesio-taping was better in improvement of median nerve cross-sectional area at hamate hook and pisiform levels, symptoms severity scale, and functional status scale, which makes the results clinically more applicable.
