Title
(EN) ACTIVE HAND ORTHOSIS
Abstract
(EN)

Active hand orthosis (20) for people with nerve-related paresis/paralysis of the hand, and for people with spastic paresis/paralysis of the hand, which comprises supporting elements (30) and moving elements (40) connecting the supporting elements (30), the moving elements (40) containing shape memory material, further comprising a control system (22), electric circuit elements (50) and a power source (60) for creating an activation signal inducing transformation of the shape memory material, and thereby deformation of the moving elements (40), characterised by that the moving elements (40) comprise: a wrist joint moving element (44), at least one finger moving element (46), and a thumb moving element (48), furthermore, in a state fitted to a lower arm (10) the supporting elements comprise: a lower arm splint (32) supporting a lower side of the lower arm (10), and leaving a wrist joint (11) free, a palm support (34) connected to the lower arm splint (32) by the wrist joint moving element (44), palm support (34) being provided at the proximal end of the fingers (15) opposable to the thumb (14), at least one finger support (36) connected to the palm support (34) by the at least one finger moving element (46), at least one finger support (36) being provided at the middle bone of the fingers (15) opposable to the thumb (14), and a thumb support (38) connected to the lower arm splint (32) by the thumb moving element (48), the thumb support (38) extending from the proximal end of the thumb (14) on the palm (13) to the lower bone of the thumb (14).
