An electromechanical device for rehabilitation includes pedals coupled to radially-adjustable couplings, an electric motor coupled to the pedals via the radially-adjustable couplings, and a control system including a processing device operatively coupled to the electric motor. The processing device configured to, responsive to a first trigger condition occurring, control the electric motor to operate in a passive mode by independently driving the radially-adjustable couplings rotationally coupled to the pedals. The processing device also configured to, responsive to a second trigger condition occurring, control the electric motor to operate in an active-assisted mode by measuring revolutions per minute of the radially-adjustable couplings, and cause the electric motor to drive the radially-adjustable couplings when the measured revolutions per minute satisfy a threshold condition, and responsive to a third trigger condition occurring, control the electric motor to operate in a resistive mode by providing resistance to rotation of the radially-adjustable couplings.

A device for use with an exerciser device, such as a reformer, which permits the adjustment of a resistance system, even when connected to a resistance source, by selectively relieving the resistance force imparted on the resistance adjustment system when changing the resistance and automatically reengaging the resistance force when exercising. A strain relief is coupled to a linkage between the resistance source and the resistance adjuster. When engaged, the strain relief selectively reduces the resistance force transmitted through the linkage to the resistance adjuster to permit movement of the resistance adjuster relative to the purchase. When disengaged the strain relief permits transmission of the resistance force through the linkage to the resistance adjuster.

A fitness machine with continuously variable magnetic-controlled damping force and combined with a manual emergency brake includes a fitness bike, a console, a magnetically controlled damping device and a resistance and brake control device. The fitness bike generates and supplies power to the console, magnetically controlled damping device and resistance and brake control device by a rotating flywheel. The magnetically controlled damping device produces continuously variable electromagnetic damping force to the flywheel. The resistance and brake control device allows a user to operate in two different modes of the continuously variable electrically controlled brake and manual emergency brake, and the function of the continuously variable electrically controlled brake may control the flywheel to produce continuously variable electromagnetic damping, so as to achieve the results of generating and supplying the required electric power, providing the continuously variable controlled damping force of the fitness bike, and combining a gradual-change brake and a multifunctional brake.

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.
