A pedaling vibrational apparatus includes a seat body, a pedal assembly, a gear plate assembly, a drive assembly and an eccentric assembly, like a lever structure. By treading the pedal assembly, the gear plate assembly drives the drive assembly to rotate. The drive assembly is connected with the eccentric assembly. A user can fully exercise muscles of the user's body during exercise, and a vibrational effect generated by the eccentric assembly can stimulate acupuncture points of the user's body to improve blood circulation. Left and right pedals of the pedal assembly can be treaded in turn to continuously drive a gear to rotate in a same direction so as to achieve an effect of acceleration and to enhance vibrations.

The present invention relates to a system for generating a force, in particular a driving force comprising: a first unit comprising a first tubular element, first magnetic means, a second unit comprising a second tubular element, where said second tubular element is coaxial with said first tubular element, second magnetic means, third magnetic means. Said first magnetic means are arranged within said first tubular element, and said second magnetic means and said third magnetic means are arranged on said second tubular element so as to be opposed to each other. Said first tubular element is arranged within said second tubular element and is configured to rotate of a predetermined rotation angle in such a way that, when said first tubular element rotates, said first magnetic means rotates with respect to said second magnetic means and said third magnetic means, so that a predetermined first force is generated by said system.

An exercise machine has a main frame and a user support movably mounted relative to the main frame for movement between a start position and an end position during an exercise. At least one user engagement device is movably mounted relative to the main frame for engagement and actuation by a user during an exercise, and a connecting linkage translates movement of the user engagement device to movement of the user support. A lifting arm is movably mounted relative to the main frame and associated with at least one of the user support, user engagement device, and connecting linkage so as to move during an exercise. A load associated with the lifting arm provides exercise resistance.

A twisting exerciser includes a base with a first shaft, a second shaft and a stop member respectively connected thereto. A first swingable unit and a second swingable unit are respectively and pviotably connected to the first and second shafts. The first swingable unit has a pad and first fan-shaped gear. The second swingable unit has a handle assembly and a second fan-shaped gear which is engaged with the first fan-shaped gear. The user holds the handle assembly, and the upper body and the lower body swing in opposite direction by the engagement between the first and second fan-shaped gears. The stop member limits the angle that the first fan-shape gears swings. The user may sits on the pad or stand on the pad to operate the twisting exerciser. The twisting exerciser is simple and safe.

An exercise apparatus includes a pair of apparatuses wearable on feet of a user. Each apparatus is configurable between expanded configurations and compressed configurations to simulate a selected motion when the user wearing the pair of apparatuses travels by foot. One of the apparatuses can move towards an expanded configuration while the other apparatus moves towards a compressed configuration.

Patient aid devices and an associated method of supporting an upper extremity are described and include a mobile upper extremity support for the patient. A support assembly supports a first side of an upper body of the user for movement along a first rail. The support assembly also allows motion of a second side of an upper body relative to the first side.

A patient aid assembly includes an upper extremity support assembly and a housing associated therewith. The housing slidingly engages a rail and allows relative movements therealong. First and second upper extremity support assemblies are received on first and second rails, respectively. An interconnecting member us hingedly connected to each of first and second housings that support the UE support assemblies.

An exercise machine comprises a motor, a gearbox coupled to the motor, a spool coupled to the gearbox, and a cable wound about the spool. The gearbox comprises bevel gears.

Sensor data is collected from a sensor monitoring a tension generating device of an exercise machine. The sensor data is analyzed to determine whether the sensor data is within a specification. In the event the sensor data is not within the specification, an error stop mode is entered for the tension generating device.
