Hypothesis
This pilot study aimed to assess the differences in center of pressure trajectory in neuropathic patients with steppage gait.
Conclusion
The study found significant differences in center of pressure trajectory between normal and neuropathic subjects, which can inform better design of orthopaedic devices.
Supporting Evidence
- The horizontal angle measured from center of pressure linear regression was positive in the control group and negative in the patient group.
- Significant distortions in center of pressure patterns indicate abnormal loads on the foot.
- The study utilized a force plate to accurately measure ground reaction forces.
Takeaway
This study looked at how people with a walking problem called steppage gait walk differently than normal walkers, which can help make better shoes and braces for them.
Methodology
Participants walked on a force plate to measure their center of pressure during gait, with 25 neuropathic patients and 20 normal subjects involved.
Limitations
The study had a small sample size and was observational in nature.
Participant Demographics
20 normal male subjects (mean age 27.55 years) and 25 male patients with various gait problems (mean age 30.24 years).
Statistical Information
