Instead of forcing wheelchair dependence onto immobile patients, we would like to provide devices that support the notion of walking again. This concept would be a wearable device to lift and maneuver one or both legs. The device would allow, for example, a stroke victim or leg-injured patient to independently and frequently exercise the affected leg toward rehabilitation, leg exercise, gravity compensation for the leg, or in some case learning to walk again. This tendon-driven device would be minimally invasive and could be configured as a pair of trousers with the tendons along the fabric. Motors can be worn on the belt and a special shoe with tendon connections would provide the necessary lift points. A modified, off-the-shelf knee support would provide the interim cable routing. And, the patient's leg bones would provide the compression members. The concept is now being studied at NIST.
Walking-Cane Leg-Lifter simple attachment to canes
Based on the RoboChair concept and as a first step to inserting a human-lift device into the healthcare industry, the LIFTER is designed to allow a persons' upper body to be lifted and the person placed on a bed, chair, toilet or even floor. Mobility is self/caregiver-powered (walking), assist-power (optional - walk with some mobility power from LIFTER), or powered (optional - full mobility power from LIFTER). Powered requires additional drive motors not shown in the graphics. Also, for typical stroke victims where the right leg is not or partially functional, a fold down, removable footrest can be optionally attached to the right side. For full mobility, footrests for both feet can fold down.
