Experimental studies on kinematics and kinetics of walking with an assistive knee brace

Gait analysis for designing a new assistive knee brace

“…The main difference between this prototype and the previous one is the location of the actuator. Different from the prototype adopted in [16] where the actuator was installed on part of knee joint, the 1 4 7 10 13 16 19 22 25 28 31 34 37 40 43 46 49 52 55 58 61 64 67 70 73 76 79 82 85 88 91 94 97 100 1 4 7 10 13 16 19 22 25 28 31 34 37 40 43 46 49 52 55 58 61 64 67 70 73 76 79 82 85 88 91 94 97 100 1 4 7 10 13 16 19 22 25 28 31 34 37 40 43 46 49 52 55 58 61 64 67 70 73 76 79 82 85 88 91 94 97 actuator used in this experiment was installed on the part of hip. As the human knee joint has motions in three planes (flexion/extension, valgus/varus, internal/external rotation), this single DOF assistive torque should only be provided when motions at the other two planes are at a minimum.…”

“…A prototype of the assistive knee brace adopted the multifunctional actuator, which was located at the lateral side of the knee joint was fabricated and tested [16]. Experiments were carried out to evaluate the kinematic and kinetic changes of walking with the assistive knee brace.…”

Medical applications of magnetorheological fluid: a systematic review

“…Guo et al [15,[72][73][74] designed a multifunctional rotary actuator that integrated motor and MR fluid into one device. With interior inner coil structure and its main design parameters optimized, this actuator could function as motor, clutch, and brake.…”
