A portable exercise apparatus including an exercise board with fixed indices marking progress made while exercising a knee which requires therapy consisting of controlled flexing and extending of the knee joint. A foot board or seated foot slide cooperatively engages and slides back and forth on the exercise board. An knee/ankle platform is removably attachable to the seated foot slide providing for active or passive knee extension stretching and a short-arc quad. A knee extension pad and roll is included for use with the slide and platform. Sensing means which may include a microprocessor control box or computer or smart device with a light and/or sound device for visual and/or auditory feedback are in communication with the exercise board provide a user with the results of flexing or extending the knee by a selected controlled amount to reach his/her range of motion goal of 110-120 degrees of knee flexion.

A computer implemented method of semi-supervised intent recognition for an exoskeleton system. In one aspect, the method includes, in response to a state transition intention input, changing the exoskeleton system from operating in a first mode with sensitivity to detecting state transitions at a first sensitivity level to operating in a second mode with sensitivity to detecting state transitions at a second sensitivity level that is more sensitive than the first sensitivity level; identifying a state transition while operating in the second mode and using the second sensitivity level; and facilitating the identified state transition by actuating the exoskeleton system.

A gait motion assisting apparatus is provided, in which a thigh phase angle calculating unit has a latest data transmission process to transmit a thigh phase angle φ(k) at sampling timing S(k) (k is an integer of 1 or more) to a gait motion timing calculating unit and store the same as a reference thigh phase angle φc. Also, a stored data transmission process transmits, instead of the thigh phase angle φ(k), a currently stored reference thigh phase angle φc to the gait motion timing calculating unit and performs the stored data transmission process only when conditions are satisfied such that a thigh phase angle at one sampling timing is smaller than the currently stored reference thigh phase angle and an absolute value of a deviation therebetween is equal to or less than a predetermined threshold, and performs the latest data transmission process in other cases.

In an assistance apparatus, when assisting a user in walking with an object, a motor generates, in a gait phase of a left leg, a tension less than a second threshold value in a first wire during a fifth period other than a first period during which a tension greater than or equal to a first threshold value is generated in the first wire, and a tension greater than or equal to the second threshold value in a second wire during a sixth period other than a second period during which a tension greater than or equal to the first threshold value is generated in the second wire, and generates, in a gait phase of a right leg, a tension less than the second threshold value in a third wire during a seventh period other than a third period during which a tension greater than or equal to the first threshold value is generated in the third wire, and a tension greater than or equal to the second threshold value in a fourth wire during an eighth period other than a fourth period during which a tension greater than or equal to the first threshold value is generated in the fourth wire.

A device performs a flexion process or an extension process with respect to a knee joint. The device includes a support frame extending in a longitudinal direction. A flexion system includes a foot support assembly configured to translate relative to the support frame in the longitudinal direction thereof and a flexion linear actuator configured to cause the translation of the foot support assembly. The extension system an extension pad assembly including a first expansion pad configured to engage an upper surface of the leg at a position above the knee joint and a second expansion pad configured to engage the upper surface of the leg at a position below the knee joint. An extension linear actuator is configured to translate the extension pad assembly with respect to the transverse direction. A power system is configured to selectively actuate each of the flexion linear actuator and the extension linear actuator.

A computer-implemented method for (1) receiving one or more characteristics of a user, wherein the one or more characteristics comprise personal information, performance information, measurement information, or some combination thereof, (2) generating, using one or more trained machine learning models, a treatment plan for the user, wherein the treatment plan is generated based on the one or more characteristics of the user, and the treatment plan comprises: (i) a dietary plan that is tailored to manage one or more medical conditions associated with the user, and (ii) an exercise plan comprises one or more exercises associated with the one or more medical conditions, and (3) presenting, via a display device, at least a portion of the treatment plan comprising the dietary plan.

In some implementations, an exosuit comprises a proximal portion, a distal portion, and a joint coupling the proximal and distal portion. The joint enables rotation of the distal portion about an axis with respect to the proximal portion. The exosuit includes a motor coupled to the proximal portion and a transmission configured to apply force from the motor to actuate the joint. The transmission includes multiple stages of reduction, including: a first stage comprising a belt that couples the motor to a drive pulley such that rotation of the motor rotates the drive pulley; and a second stage comprising (i) a winch having a spool configured to rotate with the drive pulley, and (ii) a cord that couples the spool to the distal portion such that rotation of the spool applies a force to actuate the joint.
