A standardised hand function test based on seven of the eight most common hand grips is reported. The test consists of 20 activities of daily living. The test procedure and the method of scoring are described as is our evaluation of the validity and reliability of the test. Fifty-nine tetraplegic patients were evaluated using the test before reconstructive surgery to their hands. The test score correlated well with the accepted international functional classification of the patient's arm (r = 0.76, p < 0.001). The mean test score in the arms of patients lacking sensation was significantly lower than in those with tactile gnosis (O:1-3 compared with OCu:1-3, p < 0.001).
