Summary
Healthy Korean adults exhibit distinct walking patterns based on gender. Females have shorter strides and altered joint movements, suggesting anatomical and habitual differences influence gait.
Area of Science:
- Biomechanics
- Human Movement Science
- Anthropometry
Background:
- Limited research exists on gender-specific gait patterns.
- Understanding gait differences is crucial for biomechanical analysis and potential clinical applications.
Purpose of the Study:
- To investigate gender differences in barefoot walking in healthy Korean adults.
- To test the hypothesis that gender influences gait parameters at comfortable walking speeds.
Main Methods:
- Gait analysis of 98 healthy Korean adults (47 females, 51 males) using an opto-electric system and force plates.
- Statistical analysis including independent t-tests, ANCOVA, and two-way repeated ANOVA, with normalization for body size.
- Comparison of spatiotemporal, kinematic, and kinetic gait data between genders.
Main Results:
- Females exhibited shorter height and leg length but similar cadence and pelvic width compared to males.
- Females walked slower with shorter stride length and narrower step width.
- Significant differences in pelvic tilt, hip joint (flexed-adducted-internally rotated), and knee valgus angles were observed in females.
Conclusions:
- Significant gender-based differences in gait parameters were identified in healthy Korean adults.
- These differences are likely attributable to anatomical and habitual factors related to gender.
- Findings suggest potential racial variations in gait when compared to international research.
