Title:
Myoelectric Knee
Text:
The need exists for active volitionally controlled above knee prostheses
which are more easily controlled by the amputee. Currently, control of lower
limb prostheses has been largely limited to preprogrammed, passive devices
which are awkward and difficult to control, the most popular means of
passive control being the use of fluid dampening mechanisms at the knee
joint. Active volitional control of a prosthesis permits continuous
adjustments to changing gait conditions, decreasing metabolic energy usage,
and the ability to respond to extraordinary events, such as stumbling.
A myoelectrically controlled AK prosthesis is under development at this
laboratory that provides greater conscious and subconscious active control
in gait and non gait activities.
This prototype prosthesis has three principal operating subsystems: a
myoelectric signal processor, a controller and a hydraulic pneumatic
actuator.

This seems like a good idea. It seems like a myo controlled flexion brake
alone to prevent stumbling would be a good idea.
There may be something in Japan being developed around a similar idea.
However, the above quote comes from Rehabilitation R&D Progress
reports.....1987 !
What happened to those ideas, and is anybody working on them in or out of
the VA system??
