This invention is embodied by a controlled, variable tension line, payout reel machine. A system of sensors detect line tension and line distance paid out, location, and transmit through wired and unwired communication to a microprocessor. The microprocessor is co-located with the reel structure, which in turn applies, via a brake feature, resistance to the reel which is paying out the line being pulled by the user. This invention pertains to all applications where it is desirable to control the tension in a line paid out from a reel or reel. As stated, the payout motive force is supplied by the person, animal or apparatus attached to the end of the line, opposite the reel. The invention applies to the field of precise and measured control of line tension for sport, sport training, performance testing.

A system and method for determining a patient force during a motion includes a tether adapted to be biased during a motion so that a tension force is applied. The tether is connected a motor and generates a tether force about the motor. The system controls the motor by generating a motor torque in a direction opposite the tether force. A recording module stores the motor torque at a plurality of intervals during the motion and a position of the tether. A display module generates a plot of a position of the patient versus a force generated by the patient. The position of the patient corresponds to the cumulative rotation of the shaft in the first direction about the axis of rotation of the shaft at each of the intervals. The force generated by the patient corresponds to the amount of motor torque at each of the intervals.

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.

Electromechanical rehabilitation of a user can include receiving a pedal force value from a pedal sensor of a pedal; receiving a pedal rotational position; based on the pedal rotational position over a period of time, calculating a pedal velocity; and based at least upon the pedal force value, a set pedal resistance value, and the pedal velocity, outputting one or more control signals causing an electric motor to provide a driving force to control simulated rotational inertia applied to the pedal.

A pedal assembly for electromechanical exercise or rehabilitation of a user is disclosed and can include pedals to engage appendages of a user. A spindle supports each pedal and has a spindle axis. A pedal arm assembly is located between the spindle and a rotational axle of the equipment. The pedal arm assembly is radially offset from the spindle axis to define a range of radial adjustability for the pedal relative to the rotational axle. The pedal arm assembly can include an electrically-actuated coupling assembly to adjust the radial position of the pedal in response to a control signal, and regulate motion of the user engaged with the pedals.

A resistance force is controlled such that a user's effort against the resistance force results in a first isokinetic seed movement, wherein the user is an exercise machine user using an exercise machine. The resistance force required to effect the first isokinetic seed movement is associated with a predetermined force-velocity profile. A strength determination of the user is made based at least in part on the required resistance force and the associated predetermined force-velocity profile.
