Walking speed and step length asymmetry modify the energy cost of walking after stroke.
BACKGROUND A higher energy cost of walking poststroke has been linked to reduced walking performance and reduced participation in the community. OBJECTIVE To determine the contribution of postintervention improvements in walking speed and spatiotemporal gait asymmetry to the reduction in the energy cost of walking after stroke. METHODS In all, 42 individuals with chronic hemiparesis (>6 mon...
متن کاملStep Length Estimation Using Handheld Inertial Sensors
In this paper a novel step length model using a handheld Micro Electrical Mechanical System (MEMS) is presented. It combines the user's step frequency and height with a set of three parameters for estimating step length. The model has been developed and trained using 12 different subjects: six men and six women. For reliable estimation of the step frequency with a handheld device, the frequency...
متن کاملEffect of Step Length and Step Period on Walking Speed and Energy Consumption: a Parameter Study
Stability and performance are two main issues in motion of bipeds. To ensure stability of motion, a biped needs to follow specific pattern to comply with a stability criterion such as zero moment point. However, there are infinity many patterns of motion which ensure stability, so one might think of achieving better performance by choosing proper parameters of motion. Step length and step perio...
متن کاملRelationship between step length asymmetry and walking performance in subjects with chronic hemiparesis.
OBJECTIVE To understand the relationship between step length asymmetry and hemiparetic walking performance. DESIGN Descriptive. SETTING Gait analysis laboratory. PARTICIPANTS Convenience sample of 49 subjects with chronic hemiparesis. INTERVENTIONS Not applicable. MAIN OUTCOME MEASURES Subjects walked at their self-selected walking speed over both an instrumented mat and forceplates t...
متن کاملStep length asymmetry is representative of compensatory mechanisms used in post-stroke hemiparetic walking.
Post-stroke hemiparetic subjects walk with asymmetrical step lengths that are highly variable between subjects and may be indicative of the underlying impairments and compensatory mechanisms used. The goal of this study was to determine if post-stroke hemiparetic subjects grouped by step length asymmetry have similar abnormal walking biomechanics compared to non-impaired walkers. Kinematic and ...
