Optimization of Ankle-Foot Prosthesis with Active Alignment by Passive Elements
Today, often ankle’s active prosthesis is used for transtibial amputated people’s walking, because these prostheses have some advantages such as increasing power and decreasing metabolism. In most of active prosthesis in order to create a movement or increase the force at the push-off, electrical actuators are used like a motor. In cases where a higher-power motor is necessary, the capacity, we...
متن کاملPassive Ankle-Foot Prosthesis Prototype with Extended Push-Off
Current commercially available prosthetic feet have succeeded in decreasing the metabolic cost and increasing the speed of walking compared to walking with conventional, mostly solid prosthetic feet. However, there is still a large discrepancy when compared with a non‐disabled gait, and the walking pattern remains strongly disturbed. During the stance phase of the leg, t...
متن کاملRunning head: PASSIVE ANKLE STIFFNESS IN CHRONIC STROKE 1 Measurement of Passive Ankle Stiffness in Subjects with Chronic Hemiparesis
36 Our objective in this study was to assess passive mechanical stiffness in the ankle of chronic hemiparetic stroke 37 survivors and to compare it with those of healthy young and older (age-matched) individuals. Given the importance 38 of the ankle during locomotion, an accurate estimate of passive ankle stiffness would be valuable for locomotor 39 rehabilitation, potentially providing a measu...

متن کاملAnkle-knee prosthesis with active ankle and energy transfer: Development of the CYBERLEGs Alpha-Prosthesis
This paper presents the development of the CYBERLEGs Alpha-Prototype prosthesis, a new transfemoral prosthesis incorporating a new variable stiffness ankle actuator based on the MACCEPA architecture, a passive knee with two locking mechanisms, and an energy transfer mechanism that harvests negative work from the knee and delivers it to the ankle to assist pushoff. The CYBERLEGs Alpha-Prosthesis...
