A mechatronic exercise system, e.g., for rehabilitation, having instrumented handle and pedal systems and, preferably, an interactive virtual environment is disclosed. Alternatively, the instrumented handle and pedal systems are part of a virtual reality augmenting kit that can convert most types of exercise equipment, such as a stationary or exercise bicycle, ergometer, rowing machine or the like, into full virtual reality (VR) smart systems. In another embodiment, the instrumented handle and pedal systems can each be used separately with other types of devices. In a preferred embodiment, components embedded with sensors are implemented, e.g., on a stationary, exercise bicycle to monitor physiological and biomechanical parameters of the user. Signal data from the sensing components is used to immerse the user in a VR simulation so as to provide the user with visual, auditory, and haptic feedback to the user's performance.

A therapeutic device, such as an exercise device, includes the principles of osteogenic repair by incorporating a loading mechanism into the exercise device. By doing so, the therapeutic device provides an increased osteogenic effect, thereby enhancing the benefits of the therapy. As an example, a exercise device includes a support surface for supporting all or part of the bodily tissue of an individual using the device. A linear or rotary loading mechanism associated with the frame or a rotational element of the exercise device drives the support surface at a selected load and frequency, thereby inducing mechanical loading of bodily tissue adjacent to the support surface sufficiently to facilitate the growth, development, strengthening, and / or healing of bone tissue. The loading mechanism may be incorporated into any exercise device, including standard exercise devices such as rowing machines, stair climbing machines, elliptical trainers, bicycles, cross-country ski trainers, treadmills, or weight trainers.
