We have developed a method to assess the relative motion of various structures in the human carpal tunnel (tendon, nerve, and synovium) simultaneously using ultrasound We have also developed a method of comparing these motions by means of ratios and have shown that the ratios differ in normal individuals and those with carpal tunnel syndrome. The methods include both specific testing protocols and the software to perform the specialized analyses afterwards. The method may be useful to diagnose carpal tunnel syndrome and to assess individuals at risk for carpal tunnel syndrome. It can also be used to assess the relative motion of structures entailed by certain hand activities, and thereby to judge if those activities pose risks to the person performing those activities of excessive stretching and possible injury of structures within the carpal tunnel.
