A system and method for intelligent self-calibration of target load thresholds for users of exercise machines is disclosed herein. In one embodiment, a method includes determining, by one or more processing devices, a bone geometry of a bone in a portion of a body of a user, where said portion is going to be exercised by the user performing an exercise on an exercise machine. The method also includes determining, using the bone geometry, a strain on the bone in the portion of the body of the user such that the strain triggers osteogenesis, determining a target load threshold to be added by the user to the exercise machine during the exercise to achieve the strain that triggers osteogenesis, and, while the user performs the exercise on the exercise machine, causing the target load threshold to be represented on a user interface of a computing device.

Embodiments disclosed herein are directed to personal therapy and exercise systems as well as to methods related thereto. For example, a personal therapy system can be a modular system that can include multiple therapy gear modules.

Systems and methods for a muscle signal-driven cycling system for persons with disability for rehabilitation are provided. A system comprises integrating both motor power and muscle power to facilitate rehabilitation cycling-based exercises. By using the intensity of real-time muscle activity signals as inputs, a motor applies either assistive or resistive force to rotate a gear at different speeds to facilitate or impede the cycling motion, and the electrical pulses from an electrical stimulation device can be provided to stimulate target muscles to generate muscle contraction to support the continuous cycling movement.

Systems, apparatuses, and methods for performing robotically assisted physical therapy. The system, apparatus, and method can include a motion platform having three-degrees of freedom to achieve pitch motion, yaw motion, and roll motion; a plurality of motors connected to the motion platform to enable the pitch motion, the yaw motion, and/or the roll motion; at least one sensor configured to collect data relating to position and/or motion of the motion platform; and a motion controller configured to control the motion platform based on the collected data and/or external commands.

A method and system for implementing an exercise protocol for osteogenesis and/or muscular hypertrophy are disclosed. A method may include initiating, based on the exercise protocol, a warmup session for a first exercise, where the warmup session specifies applying a first target load threshold for a first period of time. The method includes determining the warmup session is complete after the first period of time elapses. Responsive to determining the warmup session is complete, the method includes initiating, based on the exercise protocol, a resting session specifying not applying loads for a second period of time. The method includes determining the resting session is complete after the second period of time elapses. Responsive to determining the resting session is complete, the method includes initiating, based on the exercise protocol, an exercise session specifying applying a second target load threshold for a third period of time.

The present invention is generally directed to methods, systems, and computer program products for coordinating musculoskeletal and cardiovascular hemodynamics, and more directly to stationary and non-stationary exercise equipment that include adjustable behaviors and are used with repetitive activities. The equipment is adjusted automatically in real-time to alter the work output, cadence, and/or timing of the user's physical activity in response to their monitored cardiovascular and musculoskeletal signals to achieve and maintain a targeted coordination of their heart and musculoskeletal pump cycle timing.

A variable radius cam mechanism is configured for use in a weight lifting apparatus. The variable radius cam mechanism includes a disk configured to rotate about an axis. The cam mechanism includes a cable guide coupled to the disk and defining a path for a cable and a radial tangent distance between the cable and the axis. The cam mechanism further includes one or more actuators coupled to the disk and the cable guide and configured to move the cable guide relative to the disk to change the radial tangent distance during rotation about the axis. The cam mechanism includes a controller programmed to operate the one or more actuators to cause the one or more actuators to move the cable guide to change the radial tangent distance thereby changing a force transferred through the cam mechanism.
