The invention provides an exercise arrangement comprising a tiltable body support supported on a roller board. The exercise arrangement includes a tiltable or rockable body support for at least partially supporting a body part of a person. The body support is supported above a roller board, thereby allowing the exercise arrangement to not only tilt, but also to roll freely over a support surface. This arrangement allows users to exercise numerous muscle groups by a combination of tilting and rocking movements, combined with lateral movements. The exercise arrangement is especially suited for balance exercises and increases proprioception by providing a dynamic training environment.

This invention provides a new technology for management of back pain by stimulating the spinal cord in a manner that renders it refractory to transmission of deleterious or undesirable sensory input. The electrical stimulus comprises high frequency pulses in a regular or complex pattern or that are stochastically produced under microprocessor control. The stimulus is applied directly to the surface of the spinal cord from within the spinal canal, which provides important benefits over previous technology. The stimulus alleviates symptoms and signs of back pain, while minimizing the risk of side effects such as paresthesia, and potentially minimizing the effects on motor neuron transmission and proprioception.

A system has a contactless user-interface for control of the system through pre-determined gestures of a bodily part of the user. The user-interface has a camera and a data processing system. The camera captures video data, representative of the bodily part and of an environment of the bodily part. The data processing system processes the video data. The data processing system determines a current spatial relationship between the bodily part and another bodily part of the user. Only if the spatial relationship matches a pre-determined spatial relationship representative of the pre-determined gesture, the data processing system sets the system into a pre-determined state.
