Simulating ideal assistive devices to reduce the metabolic cost of walking with heavy loads
Wearable robotic devices can restore and enhance mobility. There is growing interest in designing devices that reduce the metabolic cost of walking; however, designers lack guidelines for which joints to assist and when to provide the assistance. To help address this problem, we used musculoskeletal simulation to predict how hypothetical devices affect muscle activity and metabolic cost when wa...
متن کاملSimulating Ideal Assistive Devices to Reduce the Metabolic Cost of Running
Tools have been used for millions of years to augment the capabilities of the human body, allowing us to accomplish tasks that would otherwise be difficult or impossible. Powered exoskeletons and other assistive devices are sophisticated modern tools that have restored bipedal locomotion in individuals with paraplegia and have endowed unimpaired individuals with superhuman strength. Despite the...
متن کاملCost of walking, exertional dyspnoea and fatigue in individuals with multiple sclerosis not requiring assistive devices.
OBJECTIVE To assess the cost of walking in individuals with multiple sclerosis and to investigate its relationship with dyspnoea and fatigue. METHODS In 46 individuals with multiple sclerosis and in 36 healthy controls, the cost of walking was measured during the 6-min walk test. Perceived breathlessness after walking was rated on a visual analogue scale and corrected for the distance walked....
متن کاملthe magnitude of errors associated in measuring the loads applied on an assistive device while walking
measurement of the loads exerted on the limb is a fundamental part of designing of an assistive device, which has been done by using strain gauges or a transducer. although calculation of loads applied on an orthosis coefficients achieved from calibration is a standard way, most of researchers determined the loads based on available equations. therefore, the aim of this research is finding the ...
متن کاملA Simple Exoskeleton That Assists Plantarflexion Can Reduce the Metabolic Cost of Human Walking
BACKGROUND Even though walking can be sustained for great distances, considerable energy is required for plantarflexion around the instant of opposite leg heel contact. Different groups attempted to reduce metabolic cost with exoskeletons but none could achieve a reduction beyond the level of walking without exoskeleton, possibly because there is no consensus on the optimal actuation timing. Th...
