Summary
A new gait analysis procedure accurately quantifies lateral pelvic displacement and its symmetry during walking. This method is sensitive to walking abnormalities, aiding in stroke rehabilitation.
Area of Science:
- Biomechanics
- Gait Analysis
- Rehabilitation Engineering
Background:
- Previous methods for quantifying lateral pelvic displacement lacked consideration for step-to-step variations and symmetry.
- Objective measurement of pelvic displacement is crucial for assessing gait abnormalities, particularly in stroke rehabilitation.
Purpose of the Study:
- To introduce and validate a novel procedure for quantifying lateral pelvic displacement during walking.
- To assess the amplitude and symmetry of lateral pelvic displacement in unimpaired individuals and a person with hemiplegia.
Main Methods:
- Utilized a quasi-experimental design with 3D motion analysis and reflective markers on the sacrum and heels.
- Quantified lateral pelvic displacement amplitude and symmetry relative to the base of support during a 10m overground walk.
Main Results:
- Unimpaired adults exhibited a mean lateral pelvic displacement amplitude of 40.8 mm and symmetry of 3.1 mm.
- The hemiplegic individual showed a significantly larger amplitude (88.4 mm) and asymmetry (30.9 mm), deviating towards the non-paretic side.
Conclusions:
- The new procedure effectively quantifies lateral pelvic displacement amplitude and symmetry in unimpaired adults.
- The method demonstrated sensitivity to deviations in gait associated with hemiplegia, highlighting its clinical relevance for stroke rehabilitation.
