  • Research summary

    The research study will be looking at the damage sustained to the median nerve at the wrist in patients suffering from suspected or known carpal tunnel syndrome, where the nerve becomes trapped beneath fibrous tissue at the wrist. The patients involved in the study will be asked to complete a questionnaire which will help define and detail the symptoms and pain levels experienced. A clinical examination will be performed to assess the degree of muscle wasting in the hands, and in particular the thumb. A clinical test of power of the thumb will be performed, with the recognised MRC 1-5 scale used to grade the strength. A further test of power will be performed where the patient will be asked to use the thumb to pull on a myometer, a device that will measure muscle power in Newtons (N). A standardised neurophysiological investigation will be performed whereby a small electrical stimulus will be applied to various sites on the upper limbs with the potential then recorded at a site either at the wrist or on the hand. The patient will also have the hand photographed in order to help quantify the severity of the injury. Signed consent will be taken for any photography.
