A hamstring exercise device is provided that allows a user to apply variable resistance to the hamstring muscles during exercise. The hamstring exercise device has a user sled, upon which a user may rest, slidably mounted on an angulation slide. The angulation slide is pivotably adjustable to varying degrees of inclination or declination relative to the horizontal. The user's body weight, resistance of the sled toward moving and an optional biasing means all contribute to an adjustable degree of exercise difficulty.

A universal foot exercise brace and ball device with new and useful characteristics for massaging and rehabilitating the plantar fascia is presented. An adjustable ankle brace surrounding the ankle naturally connects to a curvilinear tongue surface that rests over the top portion of the foot defining a passageway for a shock cord. An upper cord lock subsequently accommodates and sizes the shock cord, which in turn holds a spherical ball designed for massaging the tissues found at the bottom of the foot. Together, all the components of this utilitarian device work as one embodiment and integrated unit leaving the plantar fascia completely unobstructed to be massaged using this new device and method that securely holds a ball in place under the foot while it operates rolling under all sections of the plantar fascia as intended by the user.

In one aspect, a motion control system includes an actuator having an actuation member, the actuation member having a proximal end attached to the actuator on a first side of a joint and a distal end attached to an anchor element attachment point on a second side of the joint. A first sensor is configured to output signals defining a gait cycle and a second sensor is configured to output signals representing a tensile force in the at least one actuation member. A controller receives the output signals from the first and second sensors and, responsive thereto, automatically actuates the actuator, during a first portion of the gait cycle, to apply a force greater than a predetermined threshold tensile force to the anchor element attachment point via the actuation member to generate a beneficial moment about the joint and to automatically actuate the actuator, during at least a second portion of the gait cycle, to reduce a tensile force at the anchor element attachment point to a level at or below the predetermined threshold tensile force to avoid generating a detrimental moment about the joint.

A mobile training apparatus for receiving weights, in particular for sports activities, is composed of a back element and, articulated releasably on the latter, a carrying system with shoulder straps, and receiving regions for at least one weight are present on the back element and/or on the carrying system, wherein the back element extends from one end of the shoulder straps as far as the articulation at the pelvis strap. The back element is configured as a plate and can be divided into several plate parts, wherein the plate parts are releasably and separably connected to each other by a connecting element, and each plate part and/or the carrying system has at least one receiving region for receiving a weight or a weight plate.

The invention comprises a portable strength-training apparatus and system for conducting strength-training exercises using resistance bands. The apparatus of the present disclosure can serve as an anchor while conducting the strength training exercises using the resistance bands. The apparatus and system of the present disclosure can allow for safely performing the strength-training exercises at varying resistance levels while allowing exercises at any angle. The apparatus and system of the present disclosure may allow a user to strength train with the resistance bands throughout the user's entire body. The apparatus and system of the present disclosure may include a base platform with base attachment mechanisms that can be coupled with the resistance bands which are in turn coupled with human interface mechanisms such as grips, wraps, or bars.

Exosuit systems and methods according to various embodiments are described herein. The exosuit system can be a suit that is worn by a wearer on the outside of his or her body. It may be worn under the wearer's normal clothing, over their clothing, between layers of clothing, or may be the wearer's primary clothing itself. The exosuit may be assistive, as it physically assists the wearer in performing particular activities, or can provide other functionality such as communication to the wearer through physical expressions to the body, engagement of the environment, or capturing of information from the wearer.

A first exemplary aspect is a walking training apparatus including: an walking assistance apparatus attached to a lower limb of a trainee; at least one wire connected to the lower limb directly or through the walking assistance apparatus; a first wire winding mechanism configured to wind the wire for applying a pull-up force to the wire; a sensor for detecting displacement information according to a displacement of a position connected to the wire in a lateral direction; and a controller configured to control the first wire winding mechanism based on the displacement information.

An apparatus for use in assessing strength of at least one knee flexor muscle of a subject, the apparatus including a support, two securing members, each securing member securing a respective lower leg of the subject in a position that in use is substantially fixed relative to the support and at least one sensor, which in use senses a force indicative of the strength of the at least one knee flexor muscle in at least one leg of the subject while the subject performs an eccentric contraction of the at least one knee flexor muscle.

This application discloses a portable exercise device for flexibility and strengthening. In some embodiments, the device is comprised of one elastic band of surgical tubing or like material and one non-elastic band, with two pairs of looped handles tied to each end of the elastic band. These looped handles can attach to a user's limb without any need for grasping. The non-elastic end of the device can be affixed to an anchor point. The exercise device offers light but adjustable resistance via a resistance modulator, allowing the user to engage in a full range of standing and seated exercises with forces comparable to swimming. In addition, two instances of the device can be combined to engage both the user's hands and feet simultaneously.

An exercise device includes a foot support portion pivotably connected to a leg support portion and having a neutral position relative to a pivot axis. The support portion is configured to rotate about the neutral pivot axis in a first direction away from the neutral position and in a second direction away from the neutral position. The second direction is opposite the first direction. The exercise device also includes a resistance mechanism configured to exert a force on the foot support portion about the pivot axis opposite to the respective first and second directions of rotation of the foot support portion about the pivot axis.
