Can microprocessor knees reduce the disparity in trips and falls risks between above and below knee prosthesis users? [PDF]

PLoS ONE, 2022
While all lower limb prosthesis walkers have a high risk of tripping and/or falling, above knee prosthesis users are reported to fall more frequently. Recognising this, engineers designed microprocessor knees (MPK) to help mitigate these risks, but to ...
