Manual therapy in the treatment of carpal tunnel syndrome in diabetic patients: A randomized clinical trial

Abstract

Background: Generally, conservative interventions including physiotherapy modalities and manual therapy have been recommended in the management of carpal tunnel syndrome (CTS), but this subject has not been studied in diabetic patients with CTS. Therefore the aim of this study was to investigate the effects of manual therapy on diabetic patients with CTS. Methods: Thirty diabetic patients with CTS were randomly divided into two equal groups: modality group and manual therapy group. Participants in the modality group received transcutaneous electrical nerve stimulation (TENS) and therapeutic ultrasound (US) and patients in the manual therapy group received manual techniques for the median nerve and its surrounding structures. Interventions were applied 3 times weekly for 4 weeks in both groups. Visual analogue scale (VAS), symptom severity scale (SSS), functional status scale (FSS) and median neurodynamic test (MNT) were evaluated before and after the interventions in both groups. Paired t-test and independent t-test were used for statistical analysis. Results: Paired t-test revealed that all of the outcome measures had a significant change in the manual therapy group, whereas only the VAS and SSS changed significantly in the modality group at the end of 4 weeks. Independent t-test showed that the variables of SSS, FSS and MNT in the manual therapy group improved significantly greater than the modality group. Conclusions: Manual therapy techniques applied to mechanical interface of the median nerve and nerve mobilization possess more appropriate and valuable effects on hand difficulties than modalities in diabetic patients with CTS.
