Power Assist Leg relegs

DESCRIPTION

Power Assist Leg relegs is a Medical-Robots from LAP Co., Ltd.. It is built for Rehabilitation.

The Power Assist Leg 'relegs' is LAP's ankle rehabilitation-assist robot, a floor-standing footrest unit that moves a paralysed ankle up and down with air pressure, aimed at people with hemiplegia after a stroke or other cerebrovascular disease. LAP points out that ankle range of motion matters for walking, and that without training the ankle can stiffen in an extended position, making walking harder and raising the risk of trips, falls and fractures; regular home training with relegs is meant to help prevent this. The foot is placed on the device's footrest from above and the instep is covered with a hook-and-loop strap, so it can be fitted even to a contracted foot; heel height is adjusted with spacers of the same material as the hand glove. It assists ankle movement automatically, and a switch lets users trigger the up and down motion by their own will so that it feels more like moving the foot themselves. Air is pumped by a control box into bellows on the device, which expand and contract to move the joint passively and rhythmically through repeated flexion and extension. A low-pressure pump keeps it from producing excessive force, and the strength is deliberately fixed rather than adjustable, because LAP says stronger forcing makes spastic, contracted joints tense up further. LAP sells and rents the devices, offers a free three-day trial or a two-week trial at half the monthly rental, and states that they are rehabilitation aids, not medical devices, and contain no lithium-ion batteries.
