Summary
This study introduces a new gait analysis technique for footfall timing and speed assessment. The system is validated for healthy adults and shows efficiency in evaluating gait improvement in children with cerebral palsy post-surgery.
Area of Science:
- Biomechanics
- Medical Engineering
- Orthopedics
Background:
- Gait analysis is crucial for assessing motor function.
- Accurate measurement of footfall timing and speed is essential for clinical evaluation.
- Existing methods may have limitations in specific patient populations.
Purpose of the Study:
- To present and validate a novel gait analysis technique.
- To assess the system's accuracy and repeatability.
- To evaluate its utility in orthopedic patients, specifically children with cerebral palsy.
Main Methods:
- Development of a gait analysis system comprising a transmitter, receiver, conductive walkway, and PC software.
- Initial accuracy and repeatability testing with known signals.
- Validation on 20 healthy adult males.
- Application to 10 children with spastic hemiplegia before and after surgery.
Main Results:
- The technique demonstrated accuracy and repeatability comparable to literature values in healthy adults.
- Measurements in children with cerebral palsy showed the system's validity for orthopedic patients.
- The system proved efficient for functional evaluation of post-operative gait improvement.
Conclusions:
- The presented gait analysis technique is valid and reliable.
- It is effective for assessing gait in orthopedic patients, including children with cerebral palsy.
- The system provides valuable data for evaluating surgical outcomes and functional recovery.
