A stationary bicycle includes a lever arm that is pivotable about a pivot axis. A biasing device rotatably biases the lever arm about the pivot axis. The lever arm is swept through a horizontal plane when rotated about the pivot axis. A user rotates the lever arm against the bias while pedaling to preload the body for a desired therapeutic effect.

An interactive exercise system with apparatus and methods to optimize muscle strength for rehabilitation, to improve or maintain fitness, and to enhance the performance of athletes. The system uses an electronically controlled linear actuator to generate resistance against the muscular force exerted by the user. The system includes sensors configured to detect acceleration, speed, velocity, position, direction of movement, duration, and the force applied by the user. A control system preferably continuously monitors the sensors, and instantaneously adjusts the adaptive actuator. This provides a proportional counterforce to the user force throughout the entire range-of-motion. A display panel allows the user to interact with the system in real-time. The objective of the user is to synchronize the exercise performance with a selected target goal, by correlating the user's movement relative to a position on a display panel.

An information related to the position of an actuator coupled to a cable which is coupled to a motor is received. A filter is used to provide an input to a motor controller coupled to the motor, to adjust torque on the motor such that a strength curve is implemented relative to the position of the actuator.

A weight training apparatus using hydraulics or pneumatics for applying positive and negative resistance closer to a user's maximum capacity throughout a lift is provided. The apparatus allows for weight training without weights. The apparatus may provide a more effective and safer mechanism for training than conventional techniques. An aerobic apparatus using hydraulics or pneumatics for a more realistic feel is also provided. Methods of using the devices are also provided.

A gymnastic apparatus for indoor cycling training that includes two cranks with alternating movement, each of which is contrasted by a device capable of varying the resistance of the crank in real time depending on the position and load.

In some embodiments, a system for rehabilitation includes an electronic device including a memory device for storing instructions, a network interface card, and a sensor. The system includes a processing device operatively coupled to the memory device, the network interface card, and the sensor, wherein the processing device executes the instructions to determine angles while a user is engaging one or more pedals of an electromechanical device, and transmit, via the network interface card, the angles to a computing device controlling the electromechanical device, and based on the angles satisfying a range of one or more respective motion threshold conditions, wherein, while the user operates at least one of the one or more pedals, the transmitting the angles to the computing device causes the computing device to increase a diameter of a range of motion of one of the one or more pedals.

A portable mirror therapy device comprises a stiff divider panel attached to a base unit which supports the divider panel in an upright position to define two adjacent limb receiving spaces at opposite sides of the divider panel. A mirror is mounted on one face of the divider panel. A clamp mounted at a lower end of the divider panel cooperates with an underside of the base unit for securing the base unit on a support such as a table or worktop. An exercise apparatus is mounted on the device and includes a limb engaging member, which in this case comprises a handle at a mirror side of the divider panel. The exercise apparatus is a resistance load training system and comprises a load cord extending from the handle to an associated resistance element mounted within a housing on an opposite side of the divider panel to the mirror.

A resistance force is controlled such that a user's effort against the resistance force results in a first isokinetic seed movement. The resistance force required to effect the first isokinetic seed movement is associated with a force-velocity profile. It is determined whether a sufficient number of isokinetic seed movements have been performed by the user. In response to a determination that the sufficient number of isokinetic seed movements have been performed by the user, a strength determination of the user is made based on the isokinetic seed movements performed by the user.
