Using the prototype lift waker, torso motion is observed to be significantly steadier during the rise to the standing position. The force from the gas springs results in a nearly constant torso velocity during the sit-to-stand transition. Lifting force required from the legs is significantly reduced ( p < 0.0000) compared to the standard walker with a mean maximum of 224 ± 24.3 N (50.4 ± 5.5 lbf). The upper extremity force observed during sit-to-stand with the standard walker is replaced by the by the force supplied by the lift walker. In essence, the user rides the platform in the vertical direction rather than exerting effort to rise to the standing position. The mean maximum lift walker force was 1037.5 ± 40.8 N (233.3 ± 9.2 lbf). Thus, the lift walker eliminates the need for the user to supply vertical force using their muscles, and instead, provides assistive force on command.
