Abstract: A system including a set of at least three horizontal tread surfaces, and a drive system for displacing the tread surfaces vertically to form a set of stairs with a range of different rise heights. One end of a ramp is hingedly connected to the last tread surface so as to define a walking surface having a variable angle of inclination varying as a function of a vertical position of the last tread surface. The tread surfaces can assume a fully-lowered state in which the set of tread surfaces are juxtaposed as a continuous flat surface, and in which a support configuration supports the second end of the ramp so that, in the fully-lowered state, the walking surface of the ramp is horizontal, so that the tread surfaces and the walking surface together forming a continuous horizontal walkway.

Abstract: A computer-aided physiotherapeutic stair & gait system has a set of at least three horizontal tread surfaces and an associated drive system for adjusting a rise height between adjacent of the tread surfaces to form a set of stairs with uniform pitch for a range of different rise heights. A sensor set measures parameters related to physiotherapy performed using the set of stairs and provides an output to a computer system. The sensors include one or more of: a rise height sensor for sensing the pitch of the stairs, a heart rate sensor, a handrail grip position sensor, and load cells for analyzing the distribution of the weight of a patient during use of the system.
