Abstract
Active and passive muscle tension is discussed in relation to finger flexor and extensor tendons. Minimising active tension required to produce finger movement is seen as an important part of post-operative finger mobilisation following flexor tendon repair in which active movement is used. It is argued that "minimal active tension" in the flexors is equal to, or just exceeds, the passive tension in the extensors. A method of measuring passive tension in finger tendons has been described. In 24 volunteers, it has been used to determine that if the metacarpo-phalangeal joints are held flexed, there is least "minimal active tension" in the flexor tendons when the wrist is splinted in extension.
