Disclosed herein are wearable, wireless-enabled biometric sensor systems, methods for manufacturing/operating such biometric sensor systems, and robotic exoskeletons equipped with such biometric sensor systems. A biometric sensor system includes a first biometric subassembly that mounts to an upper-extremity portion of a user's appendage, and a second biometric subassembly that mounts to a lower-extremity portion of the user's appendage. Each biometric subassembly includes a respective biometric sensor that monitors a biometric characteristic of the respective extremity portion of the user appendage and wirelessly outputs a sensor signal indicative thereof. A system central processing unit (CPU), which mounts onto the user, is programmed to receive sensor signals from the biometric sensors, calculate a biometric parameter of the user appendage using biometric characteristics indicated by the received sensor signals, and command a subsystem (e.g., exoskeleton joint assembly motor module) to execute one or more control operations based on the calculated biometric parameter.

A system to facilitate stretching for a user, including a force-applying component and a subject-engaging surface, such that the force applying element is attached to a first end of a rotatable element that rotates about a first point of secured support, or fulcrum, and the subject engaging surface is operatively connected to a second end of said rotatable element, such that application of force via the force-applying component causes rotational movement of the subject-engaging surface toward the user.

An upper-limb rehabilitation assisting device includes first and second handles coupled to first and second rotating shafts and rotationally operated by hands on a paralytic limb side and a healthy limb side; first and second biosignal detecting parts that detect first and second biosignals corresponding to the paralytic limb side and the healthy limb side; first and second drive parts that drive the first and second rotating shafts; and a control part that performs a cooperative control of the first rotating shaft and the second rotating shaft. The control part controls the torques of the first and second drive parts at the time of the cooperative control of the first and second rotating shafts the basis of the degree of cooperation between the first and second biosignals.

A rehabilitation therapy aid (FIG. 4), for use in aiding a patient to regain and improve movement and control in a limb, comprises a moveable structure (51) having engagement means (53) whereby the structure can be moved by the limb of a patient (72) requiring therapy and separate engagement means (52) whereby the structure can be moved in the same direction by a therapist (71) or by the patient's stronger limb. A movement detector (56) is arranged so that the movement of the structure (51) can be tracked by the patient and/or by the therapist.

A system to facilitate stretching for a user, including a force-applying component and a subject-engaging surface, such that the force applying element is attached to a first end of a rotatable element that rotates about a first point of secured support, or fulcrum, and the subject engaging surface is operatively connected to a second end of said rotatable element, such that application of force via the force-applying component causes rotational movement of the subject-engaging surface toward the user.

The present disclosure discloses an unpowered wearable walking assistance knee equipment with gait self-adaptivity comprising a left foot power output assembly, a right foot power output assembly, a left leg knee joint assistance execution assembly, a right leg knee joint assistance execution assembly and a driving force transmission device. The equipment of the present disclosure is based on lever principle and crank block structure principle and adopts an operation mode of combining ipsilateral parallel driving input and different sides cross driving input. The self-weight of the human body is utilized as a driving force during the walking process to enable the left foot power output assembly to provide the left leg knee joint assistance execution assembly with a pulling force for its stretching and to provide the right leg knee joint assistance execution assembly with a pulling force for its bending, and to enable the right foot power output assembly to provide the right leg knee joint assistance execution assembly with a pulling force for its stretching and to provide the left leg knee joint assistance execution assembly with a pulling force for its bending, so that a torque for assisting the stretching and bending of the left leg knee joint and the right leg knee joint is generated according to a gait cycle regularity during the walking process, and the goal of walking assistance is achieved.

A rehabilitation system with stiffness measurement on a body part to be rehabilitated is disclosed. The rehabilitation system includes a rehabilitation unit and a processor. The rehabilitation unit includes an exoskeleton brace holding a rehabilitation part of user and traction lines driving the exoskeleton brace for moving. When the exoskeleton brace moves, the processor analyzes tensions of the traction lines to obtain stiffness information relating to the rehabilitation part of user.

Disclosed is a lower limbs rehabilitation exercise apparatus for curvilinear motion. The lower limbs rehabilitation exercise apparatus for curvilinear motion include: a main frame installed in an upward direction; a saddle part located at a front surface of the main frame to support a hip of a user; and a lower limbs exercise part disposed at a side of the main frame to control feet of the user to perform the curvilinear motion.

A device for rehabilitating or strengthening the ankle includes a plank that is connected by a transversely oriented hinge and a longitudinally oriented pivot, as well as a pair of compression springs at its forward end. The connections of the plank to the underlying base limit the plank to motion in two directions about two axes, thereby providing four types of therapeutic ranges of motion, including dorsiflexion and plantar flexion, eversion and inversion. A transversely slidable foot rest enables the user to hold device 21 in position with one foot while using the plank of the device to rehabilitate the other foot.

A bimanual arm trainer that provides therapeutic bimanual repetitive exercise to improve upper body movement and flexibility has a top support that is elevated relative to a ground surface. The trainer further includes: (a) first and second arm holders that are pivotable relative to the top support; and (b) first and second arm holder housings that are pivotably coupled to the top support and can be moved into a plurality of different positions and locked in place in one of the plurality of different positions relative to the top support. The first arm holder is pivotably coupled to the first arm holder and the second arm holder is pivotably coupled to the second arm holder. A reciprocating translation mechanism operatively connects the first and second arm holders such that the motion of one of the first and second arm holders is mirrored in the other of the first and second arm holders.
