Embodiments of the invention are directed to devices and methods for providing extension and flexion assistance. A device manipulates a foot of a user, thereby providing extension or flexion assistance to an ankle of the user, and includes a footplate positioned at a pre-determined distance from the user and adapted to pivot about an axis defined by the ankle as the foot extends or flexes about the ankle; and a force application system comprising a force applicator connected to the footplate, and a force application mechanism, wherein the force application mechanism is configured to apply a force to the force applicator, thereby providing the extension or flexion assistance to the foot about the ankle.

A bi-directional exercise machine has a work arm, first and second cams coupled to the work arm, a resistance mechanism, and a pulley assembly that couples the resistance mechanism to the work arm via the first and second cams so that movement of the work arm is resisted by the resistance mechanism according to first and second resistance profiles provided by the first and second cams, respectfully. A primary pulley cable has a first end coupled to the first cam and a second end coupled to the second cam. When the work arm is in a rest position, the ends of the primary pulley cable extend from cable tracks of the cams, respectively, at a tangent so that the resistance mechanism applies a resistance force on the work arm via the pulley assembly immediately upon movement of the work arm out of the rest position.

A training apparatus includes a fixed frame, a training rod, a motor, rotation information detection sensor, tilt angle and position difference calculation units, determination, motor drive and position difference eliminating units. The training rod is supported by the fixed frame in a manner capable of being tilted by a motor about at least an X-axis or a Y-axis so as to hold the limb. The tilt angle calculation unit calculates a tilt angle of the training rod. The position difference calculation unit calculates a position difference. The determination unit obtains the position difference every time when a second time period elapses. If the position difference generated in the second time period is a first threshold or lower, the motor drive unit drives the motor so that the position difference is accumulated and maintained. The position difference eliminating unit resets the position difference at a predetermined timing.

An apparatus (1) for exercising muscles comprises a power arm (2), which is pivotable about a pivot shaft (5), which is disposed on a holding element (6). The first articulation point (7) at which a compression spring element (9) is linked to the power arm (2) is adjustable along the power arm (2). To achieve this, one end region (8) of the compression spring element (9) is provided with a first joint surface (14), and a series of second joint surfaces (16), which are designed complementary to the first joint surface (14), is disposed across an adjustment zone (10) along the power arm (2). The first joint surface (14) is operatively connectible to one of the second joint surfaces (16), and the power arm (2) is pressed via a further spring element (18) toward the one end region (8) of the compression spring element (9) such that the two operatively connected joint surfaces are kept in contact with each other. Resulting thereby is a simple possibility of adjustment of the force to be applied to the power arm.

A device for rehabilitating patients especially with peripheral nervous system paralysis. The rehabilitation device comprising a remote control terminal, a base, an arm mounted to a column with adjustable height containing an motor propelling the arm and at least two electrodes of the electromyography (EMG) sensor according to the disclosure is characterized in that the actuator (7) enables the extension (4) to move within the angular range of 360°, while the EMG signal from the sensor connected to the muscle or muscles of the patient is transmitted to the network of the motor controlling module (2) and then further by radio or cable connection to a remote control terminal (1).

An exercise apparatus with an adjustable rotating element around which a force transferring material wraps either clockwise or counterclockwise to provide bidirectional rotational resistance for exercising. The force transferring material is preferably guided to remain in close proximity to the rotating element while wrapping around the rotating element.

An exercise machine may include a reciprocating linkage that supports one or more pedals configured to move in a closed loop (e.g., elliptical) path as a user exercises with the machine. The exercise machine may be adjustable to vary a characteristic of the exercise provided by the machine, for example by changing an incline of a rail supporting the reciprocating linkage, and thus an angle of the closed loop path. The exercise machine may vary the incline with a lift mechanism operatively associated with the front upright frame of the machine, which may also support a resistance assembly, all in a compact form factor that may be more aesthetically pleasing and practical for relatively smaller exercise spaces.

A portable single bicep exercising machine is disclosed. The machine may comprise articulable framework running about a length of a user's given arm. This framework may be divided into upper framework and lower framework, with an articulable fulcrum connecting the upper framework to the lower framework. In use the upper framework, at an under arm pad, may be retained in a user's should/armpit region; while the lower framework may comprise a handle to be engaged by the user's hand of that same arm. Also between this upper framework and this lower framework may be one or more tension means, such that when the handle is articulated towards the under arm pad, about the fulcrum, that articulation is through resistance. It is such resistance that exercises the bicep of that same given arm.

An exercise machine with adjustable handles that provide for multiple handle positions. The exercise machine with adjustable handles generally includes a frame with one or more rails, a carriage movably positioned upon the rails, and a pair of adjustable handles positioned near an end of the frame. The adjustable handles each have a handle portion that is movably connected to a corresponding handle stanchion to pivot from a storage position to an extended position.

Provided is a training device that suppresses unintended operation of an operation rod when executing an operation mode in which the operation of the operation rod is controlled based on a force applied to the operation rod. The training device includes the operation rod, a motor, a force detection unit, a rotation information output sensor, a first command calculation unit, and a force correction unit. The operation rod moves a limb. The motor operates the operation rod in a direction of degree of freedom. The force detection unit detects a force component and outputs a force component signal. The rotation information output sensor detects an operation position of the operation rod in a corresponding direction of degree of freedom. The force correction unit calculates a corrected force component value based on the operation positions of the operation rod and the force component signal. The first command calculation unit calculates a first motor control command based on the corrected force component value.
