Abstract
A system for arm therapy comprises a first drive (M2) that can be fixedly connected to an element (10) determining the position of a user (19) and rotationally driving, about a first axis (A2), a part (21, 22, 23, 24, 25, M1, 26) of the arm therapy system which can be connected to an upper arm module (26, M3, M4). The driven part of the arm therapy system comprises a second drive (M1) adapted to rotationally drive said upper arm module (26, M3, M4) about a second axis (A1), wherein said second axis (A1) is oriented orthogonal to the first axis (A2). The system can provide a statically determined exoskeleton with correct anatomical axes and misaligned technical axes.

11-17. (canceled)
A system for arm therapy, having:
- an upper arm module comprising:
- a driven part of the arm therapy system connected to the upper arm module;
- a first drive adapted to be fixedly connected to an element determining the position of a user and rotationally driving, about a first axis, the driven part,
- a second drive associated to the driven part and adapted to rotationally drive said upper arm module about a second axis, and
- at least one light source for generating at least one light beam being aligned with the first axis or oriented in parallel to the second axis,
- wherein said second axis is oriented nonparallel to the first axis.
A system for arm therapy, having:
- an upper arm module comprising:
- a driven part of the arm therapy system connected to the upper arm module;
- a first drive adapted to be fixedly connected to an element determining the position of a user and rotationally driving, about a first axis, the driven part,
- a second drive associated to the driven part and adapted to rotationally drive said upper arm module about a second axis, and
- a profile adapted to provide a connection between the first drive and the second drive,
- wherein said second axis is oriented nonparallel to the first axis,
- wherein the second axis comprises a minimal distance from the first axis, and
- wherein the first drive is oriented in parallel to the anteriorposterior or rostrocaudal axis of the user.
The system according to claim 11, wherein said driven part of the arm therapy system can be pivoted and fixed in two minor-inverted positions on either side of an axis being in parallel to the dorsoventral axis of the user and wherein the upper arm module can be pivoted around the second axis for switching the system from right arm use to left arm use and vice-versa.
A system for arm therapy, having:
- an upper arm module comprising:
- a driven part of the arm therapy system connected to the upper arm module;
- a first drive adapted to be fixedly connected to an element determining the position of a user and rotationally driving, about a first axis, the driven part,
- a second drive associated to the driven part and adapted to rotationally drive said upper arm module about a second axis,
- a weight compensating elastic element,
- a cable attached to said weight compensating elastic element,
- at least one rotatable element adapted to be rotated about the second axis comprising at least one fixation point for said cable outside said second axis, and
- a profile adapted to provide a connection between the first drive and the second drive and having a non-pivotable element,
- wherein said second axis is oriented nonparallel to the first axis, wherein the upper arm module is affixed to said rotatable element, wherein said weight compensating elastic element is attached to the non-pivotable element of the profile between the two drives.
