The invention belongs to the technical field of knee joint orthotics, and discloses a four-bar linkage knee orthotics applying a fabric sensor, which integrates a gait self-adaptive instantaneous center adjustable hinge module through the design of a four-bar linkage mechanism, and shows extremely high flexibility and stability. By applying the mechanical bionics principle, the instantaneous rotation center track of the knee joint of a wearer is comparable with that of the knee joint in a normal physiological state, so that the corrector can be adaptively adjusted according to the gait and walking habit of a user, and a more fitting and natural auxiliary effect is provided. The stretching aid adopts a'safety belt 'locking mechanism and a'quasi-lever' stretching aid mechanism, so that the safety in the using process is remarkably improved, meanwhile, the body burden of a wearer is effectively relieved, and the remarkable stretching aid effect is achieved.

A powered device augments a joint function of a human during a gait cycle using a powered actuator that supplies an augmentation torque, an impedance, or both to a joint. A controller estimates terrain slope and modulates the augmentation torque and the impedance according to a phase of the gait cycle and the estimated terrain slope to provide at least a biomimetic response. The controller may also modulate a joint equilibrium. Accordingly, the device is capable of normalizing or augmenting human biomechanical function, responsive to a wearer's activity, regardless of speed and terrain, and can be used, for example, as a knee orthosis, prosthesis, or exoskeleton.
