Motor-driven Rehabilitation Device

Raplus(ラプラス)02The development of a motor-driven rehabilitation device draws on R&D for robotic leg prostheses, and is part of an effort to make this technology more broadly useful not just for patients with missing legs, but for anyone needing to increase physical strength. By making use of existing equipment, to which it attaches very simply, the device saves its users time—which is precious during a rehabilitation session.

In rehabilitation work, accelerometers in the device are used to detect the timing of walking strides. At the moment when the foot contacts the ground, assistive force in proportion to the bending angle of the knee is generated—this prevents the knee from buckling. Then, when the foot lifts off the ground, torque control frees the joint and allows a power-assisted but natural walking stride.


Raplus(ラプラス)The development of the motor-driven device was carried out in collaboration with doctors and physiotherapists at Tokyo hospitals (2014). In the future, we hope to build a network to share the walking data generated by use of the device. This should aid users in establishing the most efficient ways of employing the device in rehabilitation, as well as provide a forum for patients with similar conditions to connect with and support each other.
