Abstract :
A novel device has been designed to study falling potential, the sliding linear investigative platform for analyzing lower-limb stability (SLIP-FALLS). The SLIP uses air bearing technology to manipulate friction levels between its translating surfaces. This ability to control friction makes possible new tests of postural instability, of slipping and falling, and of neurological control. Subject response can be incorporated into a control/feedback loop where coupling between the platform and the sway pattern can be adjusted. Translations or “controlled slips” of up to 28 cm are possible at velocities ranging from 0.05 to 50 cm/sec
