Aetiology of work-related carpal tunnel syndrome: the role of lumbrical muscles and tool size on carpal tunnel pressures

Article Abstract:

Lumbrical muscle incursion and pressure on the palm are responsible for the increase in carpal tunnel pressure. The increase depends on the distribution of forces, related to the size and shape of the tool used, on the palm. The carpal tunnel pressure is higher in the fist position as compared to other extended positions without the tube. The movement of the fingers from the fully flexed to extended positions reduces carpal tunnel pressure. The pressure is greatly reduced with the removal of lumbrical muscles and the tubes while maintaining the finger extension position.

A gap detection tactility test for sensory deficits associated with carpal tunnel syndrome

Article Abstract:

Sensory deficits common in carpal tunnel syndrome were studied using a gap detection tactility test. The test is easy to administer and was able to provide quick measures of tactile sensitivity. Accuracy is guaranteed if the method is used to detect and monitor tactile sensitivity loss in workers due to its low inter-subject variability.
