The present invention relates to an exoskeleton interface apparatus that parallels human arm motion and is comprised of a serial assemblage of five powered linkages and joints based at a rigid support structure worn on the torso of the human subject. Such apparatus generates shoulder rotation using three orthogonal revolute joints mounted on serial linkages encompassing and intersecting at the anatomical glenohumeral joint. Elevation of the shoulder joint is articulated using a link member driven by a single revolute joint mounted in the torso structure. Passive adjustable linkages are used to match variation in anatomical forearm length, upper arm length, and scapula-to-glenohumeral radius. A plurality of integrated dc motor/harmonic drive transmission modules is co-located on adjoining linkages to power the joints. Force is exchanged with the human at the handgrip and elbow brace, and reacted to the torso structure via the base attachment. The present invention is applicable in particular to rehabilitation of the shoulder.

The invention discloses a wearable shoulder joint rehabilitation training device. The device has the characteristics of exercise flexibility, wearing comfort and training safety. The device is composed of a movement mechanism and a support adjustment mechanism. The support adjustment mechanism is used to adjust the position of the movement mechanism relative to the shoulder joint of the human body, and fix the entire rehabilitation training device at an appropriate position on the back of the human body. The driver of the motion mechanism is four pneumatic muscles in a vertical motion state, which can respectively control the two groups of movements of the upper arm around the shoulder joint, flexion and extension, abduction and adduction, and the compound movement of these two groups of movements. With the cooperation of the angular displacement and the tension sensor, the active and passive coordinated movement of the movement mechanism and the upper arm can also be realized. The movement mechanism drives the upper arm movement with the help of two sliders for passive movement, which overcomes the problem of upper limb movement difficulties caused by the misalignment between the movement center of the mechanism and the shoulder joint, and ensures the comfort and safety of the training during rehabilitation training .
