A Quasi - Passive Knee Exoskeleton to Assist During Descent
نویسندگان
چکیده
A pneumatic exoskeleton intended to decrease the muscle activity of the knee extensors during walking on a negative slope is presented. The device consists of an air spring that can be engaged and disengaged via a solenoid valve. When engaged, the air spring resists knee flexion. A preliminary evaluation of the device was conducted with a single healthy subject. During testing, the EMG activity of the rectus femoris decreased by 15%, while the EMG activity of the vastus medialis increased by 8%.

A Quasi-Passive Leg Exoskeleton for Load-Carrying Augmentation
A quasi-passive leg exoskeleton is presented for load-carrying augmentation during walking. The exoskeleton has no actuators, only ankle and hip springs and a knee variabledamper. Without a payload, the exoskeleton weighs 11.7 kg and requires only 2 Watts of electrical power during loaded walking. For a 36 kg payload, we demonstrate that the quasi-passive exoskeleton transfers on average 80% of...
متن کاملDesign of a Comfortable Pure Moment Knee Exoskeleton
Lower-limb exoskeletons have the potential to enhance rehabilitation [1], assist in walking with gait impairments [2], reduce the metabolic cost of normal [3] and load-bearing walking [4], improve stability [5] and probe interesting questions about human locomotion [6]. The ankle produces larger peak torques and performs more positive work than either the hip or the knee during locomotion [7], ...
متن کاملEffect of exoskeletal joint constraint and passive resistance on metabolic energy expenditure: Implications for walking in paraplegia
An important consideration in the design of a practical system to restore walking in individuals with spinal cord injury is to minimize metabolic energy demand on the user. In this study, the effects of exoskeletal constraints on metabolic energy expenditure were evaluated in able-bodied volunteers to gain insight into the demands of walking with a hybrid neuroprosthesis after paralysis. The ex...
متن کاملLinking the mechanics and energetics of hopping with elastic ankle exoskeletons.
The springlike mechanics of the human leg during bouncing gaits has inspired the design of passive assistive devices that use springs to aid locomotion. The purpose of this study was to test whether a passive spring-loaded ankle exoskeleton could reduce the mechanical and energetic demands of bilateral hopping on the musculoskeletal system. Joint level kinematics and kinetics were collected wit...
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...
