An apparatus for the objective and quantitative measure of hand function comprising an inflatable bladder 1 in fluid communication with a pressure transducer 3 the output of which is connected to a programmable integrated circuit 9 which accords the change in pressure of the fluid within the bladder and calculates the rate of change of the logarithm of the pressure with respect to time between predetermined lower and upper pressure levels during which the rate of change is substantially linear, and display means 11, 12 and 13 for diplaying said rate of change of logarithmic pressure with respect to time as well as the maximum pressure achieved, the elapsed time at which the predetermined lower and upper pressures and a third predetermined intermediate pressure are attained and the correlation coefficient of said linear portion. The rate of change of the logarithmic pressure with respect to time or grip rate has been found to be a measure of the functionality of the hand and to be independent of age, sex and strength and to be substantially identical for both the left hand and the right hand.
