Abstract
The same orthosis can be used to sequentially move joints of different fingers of a hand. A hand cuff of the orthosis is mounted on the hand. Mechanisms operable to move the joints are connected to the hand cuff at locations aligned with the fingers. The mechanisms are connected with the fingers. The joints of the fingers are moved by operating the mechanisms. The joints and first and second portions of the fingers define on one side of the joints outer sectors which decrease in angle as the joints are extended. Force is applied to the first and second portions of the fingers to move the joints by providing relative rotation between internally and externally threaded members disposed in the outer sectors. Actuator members connected with the internally or externally threaded members are moved along paths that extend through the joints.
