Summary
Problematic posture affects walking stability. A new wearable system and AR modeling analysis improved rhythmic hip fluctuations and walking stability in female students.
Area of Science:
- Biomechanics
- Human movement analysis
- Wearable technology
Background:
- Problematic posture and back issues significantly reduce walking stability.
- Direct analysis of movement stability from raw sensor data is challenging.
Purpose of the Study:
- To analyze the impact of posture on walking stability.
- To evaluate a new wearable measurement system and AR modeling for gait analysis.
- To assess the effectiveness of posture correction on walking stability.
Main Methods:
- Development of a portable, wearable measurement system with two accelerometers.
- Application of Autoregressive (AR) modeling for impulse response analysis.
- Evaluation of hip fluctuation rhythmicity during walking in female students.
Main Results:
- The wearable system facilitated data collection, but raw data analysis was difficult.
- AR modeling of impulse response provided clear metrics for stability evaluation.
- Correct posture significantly improved the rhythmic fluctuation of hip movement during walking.
Conclusions:
- AR modeling is effective for evaluating improvements in walking stability.
- Posture correction can enhance gait rhythmicity and stability.
- The developed system, combined with AR modeling, offers a viable approach to gait analysis.
