Split-crank pedaling devices and methods of operation support patient use and rehabilitation, particularly for stroke patients. A split-crank pedaling device includes first and second crank assemblies. First and second motors are operably connected to the first and second crank assemblies. A first shaft sensor produces an indication of a position of the shaft of the first crank assembly. A second shaft sensor produces an indication of a position of the shaft of the second crank assembly. A controller is communicatively connected to the first and second motors and the first and second shaft sensors and calculates a phase error between the positions of the first and second shafts and a predetermined phase relationship between the first and second shafts. The controller operates at least one of the first motor or the second motor to provide a supplemental torque to one of the first crank assembly and the second crank assembly.

An epicyclic pedalling apparatus comprising: a first epicyclic arm comprising a first pedal crank arm connection for coupling a first pedal crank arm to the first epicyclic arm to enable pedalling of said first pedal crank arm about a first spindle axis; and a second epicyclic arm comprising a second pedal crank arm connection for coupling a second pedal crank arm to the second epicyclic arm to enable pedalling of said second pedal crank arm about a second spindle axis; wherein the apparatus is arranged to enable: (i) the first epicyclic arm to rotate to move the first spindle axis, and (ii) the second epicyclic arm to rotate to move the second spindle axis.

A pedal cycle apparatus is disclosed in which a foot of a medically incapacitated user thereof engages a pedal for moving the pedal orbitally about a rotational axis of a crank hub. The apparatus includes a crank arm having a proximal and a distal end, the proximal end of the crank arm being rotatable about the rotational axis of the crank hub. A fastener fastens the pedal relative to the crank arm at a selectively variable radial distance from the rotational axis of the crank hub. The arrangement is such that in use of the pedal cycle apparatus, the foot of the medically incapacitated user engages the pedal so that the pedal moves orbitally about the rotational axis of a crank hub. The pedal rotates about an axis of rotation which is disposed parallel to the rotational axis of the crank hub such that selection by the user of an optimum radial distance of the pedal from the rotational axis of the crank hub is permitted.

The invention relates to the field of sports and medicine, specifically to training devices, more particularly to an elliptical exercise device suitable for simultaneous training of shoulder and pelvic girdle muscles in a human. Accordingly, it is desirable to provide an exercise device for training trunk muscles, the shoulder girdle and the pelvic girdle in a human and, at the same time, to enable simulation of various motion patterns by activating different groups of muscles, joints, the locomotor system in a human in general and especially muscles which hold the vertebral spine. It is further desirable to enable optional correction of their load during the process of coordination of motor activity (locomotion) of the human body through simultaneous elliptical motions of hands and feet, which, in addition to the load on the shoulder girdle and the pelvic girdle muscles, simultaneously provide preferably stretching load on muscle groups which hold the vertebral spine.

A multifunctional arm cranking exerciser includes an omnidirectional support bracket assembly, which comprises a five-way bracket mounted to a top thereof and having a left side to which a left arm exercising device is mounted and a right side to which a right arm exercising device is mounted. Also mounted on the five-way bracket are a damping adjustment device and a quick release pin device. The quick release pin device allows for quick coupling and positioning of left and right arm cranks of the left and right arm exercising devices at an angular difference of 0 degree or 180 degrees and also allows for quick release and decoupling of the left and right arm exercising devices to be independent of each other. The damping adjustment device adjusts and regulates a level of damping for achieving an effect of efficient exercising.

A transmission device is provided for bodybuilding devices or bicycles, including an axle that is operatively coupled to a sprocket assembly for collaborative operation. Two cranks are provided, having contact surfaces including one way bearing mounted thereto for fitting to two ends of the axle. Two clutch control assemblies are controllable through a wire control assembly such that the clutch control assemblies are selectively engageable with or disengageable from two cranks respectively to set the cranks in an operation mode of regular bicycle pedaling or an operation mode of one side pedaling alone or two side parallel pedaling. An important feature is that the wire control assembly is of an arrangement involving a mateable combination of two halves of which the parts are made of plastics, where assembly for centering is achieved with recess-projection engagement for better assembly accuracy.

A physical fitness device that simulates the motion of horseback riding. Innovative features of the present invention include a horseback riding simulation post which extends both vertically, at a vertical angle toward a rider seated on the device, and an upwardly extending longitudinal section which extends toward a rider on the exercise device seat and terminates in a transverse handle which enables the user to grasp the handle with both hands or one hand. There are a pair of parallel crank arms with a respective one of the crank arms adjacent opposite sides of the exercise device with each crank arm having an upwardly extending section extending forwardly or rearwardly.

An exercising apparatus for exercising at least one limb, having a supporting frame and at least one crank which is arranged on a rotation shaft assigned to the supporting frame, and having at least one limb support which can be fastened to the at least one crank at different radial distances from the rotation shaft. A detector is provided for detecting the radial distance of the at least one limb support from the rotation shaft. The invention further relates to a limb support and to a method for determining the force acting on a limb support of an exercising apparatus.

An exercise device with advanced bench-cycling exercises for glute, abs and leg toning, for use in both the stomach down and up positions, has: a bottom support and at least one main support stem extending upwardly; a main joint body support frame rotatably connected to the support stem to allow lower support and upper support bars to be tiltable. The upper support bar is sufficient to support at least a portion of a human torso, and is rotatably connected to the main joint; one or two lower support bars adjustable in length, and having a top portion connected to the main joint, upper support bar or the at least one support stem; and a bottom portion extended away from the main joint; two cranks located on the bottom portion of the lower support bar; and a pair of pedals separately connected to their cranks, the cranks being adjustable in length.
