An orthosis device for a subject and a rehabilitation system including the orthosis device includes a main housing assembly configured to be worn on an upper extremity of the subject and comprising a motor mechanism configured to actuate movement of at least one finger of the subject. A finger interface assembly is connected to the main housing assembly and configured to be secured to at least one finger of the subject and to induce, as actuated by the motor mechanism, flexion and extension motion of the at least one secured finger. The orthosis device is configured to leave unsecured to the orthosis device at least one finger that is not the at least one finger secured to the finger stay assembly.

Orthosis systems and rehabilitation of impaired body parts

An orthosis device for a subject includes a main housing assembly configured to be worn on an upper extremity of the subject, and a body part interface assembly configured to be secured to the portion of the upper extremity and induce, as actuated by a motor mechanism, flexion and extension motion of the secured body part. A flexible intermediate member is interposed between the main housing assembly and the body part interface assembly, and is configured to flex or extend responsive to actuation by the motor mechanism to cause the body part interface assembly to flex or extend the secured body part.

A system for moving or assisting in movement of a body part of a subject, as well as a rehabilitation system including such a movement assistance system, includes a body part interface configured to be secured to the body part, and a motor-actuated assembly connected to the body part interface to move the body part interface to cause flexion or extension movement of the body part. A force sensing module is configured to measure forces applied between the body part interface and the motor-actuated assembly to ascertain at least one of volitional flexion and volitional extension movement of the body part by the subject, among other functions that may be implemented in movement assistance and rehabilitation systems using the disclosed force sensing module designs.

Rehabilitating an impaired body part of a subject such as a stroke patient includes systems, devices, and methods using an orthosis system configured to attach to the impaired body part and to move or assist in movement of the impaired body part. A control system is configured to operate the orthosis system in a mode in which the orthosis system first allows the subject to move volitionally or attempt to move volitionally the impaired body part in a predefined motion and then operates to move or assist in the predefined motion of the impaired body part. Additional modes of operation include a brain computer interface mode of operation and a mode in which the orthosis system operates in a continuous passive mode of operation comprising a plurality of repetitions of an exercise to move the impaired body part.
