A Low-Cost Electronically Controlled Pneumatic Knee with Passive Four-Bar Stance Stability and Semi-Active Swing Damping: A Single-Case Feasibility Study
Microprocessor-controlled knee prostheses (MPKs) face limited accessibility in resource-constrained environments due to high implementation costs and excessive power consumption associated with complex actuators. This study examines the technical feasibility of a low-cost electronically controlled pneumatic knee (ECPK)...
