The tourniquet test devised by Gilliatt was used in 54 patients with carpal tunnel syndrome and its value was assessed in diagnosis and prognosis. The test procedures dysaesthesia in the median territory when the tourniquet is inflated above the systolic pressure. The value of the test was similar to that of electrical stimulation of the nerve. When the test was positive after less than 15 seconds, the anatomical lesions were severe in most of the cases. It is concluded that the test has both diagnostic and prognostic value.
