Summary

Carpal Tunnel Syndrome (CTS) is a recognisable pattern of symptoms and signs, which are caused by compression of the median (middle) nerve as it passes through the carpal tunnel at the wrist.

This condition affects individuals by causing pain, numbness, tingling sensations and sometimes weakness in the fingers and may extend to shoulder and neck areas. The cause for most cases is unknown (idiopathic) though some common conditions are associated with an increased incidence, including obesity, pregnancy, hypothyroidism, arthritis, diabetes, and trauma.

Diagnosis is primarily clinical and the condition is easily recognised from the characteristic symptoms in straightforward cases but diagnostic support is provided by investigations such as nerve conduction studies and ultrasound imaging.

Treatment may include splinting, local steroid injection at wrist, activity modification,physical or occupational therapy (controversial), medications, and surgery. Treatment with local therapeutic ultrasound has been suggested to be effective but existing trials are inconclusive.

Wrist splinting is only partially effective with a success rate of 34%, Steroid injection is followed by frequent relapses and there remains uncertainty about the safety of serial injections. Surgery is effective but has a small but significant incidence of permanent complications. Any demonstrably effective and safe addition to the therapeutic options would be a significant advance in treatment. Therapeutic ultrasound at present appears a promising option, having a very good safety record but so far uncertain evidence of efficacy.

In our trial patients, with mild carpal tunnel syndrome, confirmed by nerve conduction studies, will all be given wrist splints so that no patients will be left untreated. They will be randomly allocated to either therapeutic or sham ultrasound therapy (20 sessions over 7 weeks) and followed up for 1year. The patients, operators of the ultrasound equipment and assessors will all be blind to treatment allocation.

The effect of treatment on symptoms will be assessed using a validated questionnaire and nerve conduction studies will be repeated at completion of the ultrasound treatment, 6 and 12 months.

This study is designed to find out to whether therapeutic ultrasound is an effective treatment for carpal tunnel syndrome (CTS).
