Background The carpal tunnel syndrome (CTS) is the most common neuropathy (1). The etiology isn't properly known, but CTS is produced by the chronic compression of median nerve while passing through carpal canal can be associated with this disease (2).
Objectives The aim of this study was to investigate the efficiency of extracorporeal shockwave therapy (ESWT) in the treatment of CTS.
Methods 49 hand with the diagnosis of CTS were included in the study. Patients were randomised in ESWT (n=29 hands) and sham (n=20 hands) groups. Patients were randomly allocated to receive 1 session per week for 3 weeks of either sham or active ESWT. All patients were prescribed with tendon and nerve gliding exercises and hand-wrist splint which used night. Patients were evaluated before the treatment, and at the end of the first week, first month and third month after the last ESWT treatment session with Boston Scale (symptom severity and functional capacity), Visual Analogue Scale (VAS) for pain and paresthesia assessment, for muscle strength hand gross grasp and electroneurophysiological parameters.
Results A total of 38 patients completed the study with 29 wrists in active ESWT and 20 wrists in sham ESWT groups. Groups were similar in age, sex, duration of symptoms, hand gross grasp and electrodiagnostic parameters (P>0.05). In both groups, significant improvements were observed in VAS, Boston Scale and hand gross grasp after treatment. In both groups, there was no statistically significant improvement in electromyographic variables after treatment (p>0.05). However there was no significiant differrence between two groups in all of clinical and electrodiagnostic parameters.
Conclusions Although ESWT was effective in symptoms in CTS but this efficacy isn't superior to placebo. Our results indicated that ESWT was effective in pain and clinical variables in CTS. Wider and high-quality studies are needed to further demonstrate the effectiveness of ESWT in treatment of CTS.
