Hypothesis
Can a wearable sensor system accurately measure joint angles and stride length during gait?
Conclusion
The wearable sensor system can measure joint angles and stride length with stable accuracy, showing high correlation with common gait patterns.
Supporting Evidence
- The system measured joint angles with an average RMSE of about 4 degrees.
- High correlation was found between joint angles and stride velocity.
- Stride length measurement errors were less than 10% for most strides.
Takeaway
This study tested a new wearable sensor that can help doctors see how people walk and move their legs, which can be useful for helping patients recover.
Methodology
The study involved measuring joint angles and stride length using a prototype wearable sensor system during walking tests with healthy subjects.
Limitations
The study was limited to healthy subjects and did not test the system on patients with motor disabilities.
Participant Demographics
3 healthy male subjects aged 22-23 years.
