Ultrasonic motion analysis system--measurement of temporal and spatial gait parameters.
The duration of stance and swing phase and step and stride length are important parameters in human gait. In this technical note a low-cost ultrasonic motion analysis system is described that is capable of measuring these temporal and spatial parameters while subjects walk on the floor. By using the propagation delay of sound when transmitted in air, this system is able to record the position o...
متن کاملEstimation of Spatial-Temporal Gait Parameters Using a Low-Cost Ultrasonic Motion Analysis System
In this paper, a low-cost motion analysis system using a wireless ultrasonic sensor network is proposed and investigated. A methodology has been developed to extract spatial-temporal gait parameters including stride length, stride duration, stride velocity, stride cadence, and stride symmetry from 3D foot displacements estimated by the combination of spherical positioning technique and unscente...
متن کاملThe Effect of Spatial and Temporal Parameters on the Energy Expenditure of Orthotic Gait of Paraplegic
Objectives: Although for those spinal cord injury (SCI) patients with paralysis of the legs but not at arms, the primary means of mobility post injury is the manual wheelchair, there are many physiological and psychological advantages to standing and walking, such as improvement in respiratory function, lower limb weight bearing and preventing osteoporosis, pressure sores prevention etc. High m...
متن کاملTemporal and spatial parameters of gait during pregnancy.
PURPOSE The objective of this study was to describe spatial and temporal parameters during gait in pregnant women, and to compare it with women in post-partum and with a control group. METHODS To investigate alteration in natural locomotion, we used an electronic walkway (GAITRite system). Fifty-eight pregnant women (four last months of pregnancy), nine post-partum women and twenty-three heal...
