Summary
Establishing normal gait parameters is crucial for diagnosing joint disease. This study defines normal knee angle and moment ranges, finding peak knee flexion moment correlates with walking speed, while coronal knee angle does not.
Area of Science:
- Biomechanics
- Orthopedics
- Human Movement Science
Background:
- Three-dimensional gait analysis provides joint angle and moment data.
- Normal ranges for these parameters, especially concerning walking speed, are often unavailable in literature.
- Joint disease patients typically exhibit slower walking speeds and shorter strides.
Purpose of the Study:
- To establish normal ranges for knee angles and moments during gait.
- To investigate the relationship between gait parameters and walking speed.
- To provide a reference for clinical diagnosis in patients with joint disease.
Main Methods:
- Gait analysis was performed on 10 healthy adult males (18-63 years).
- Subjects walked at various speeds, from very slow to very fast.
- Knee angles and moments in sagittal and coronal planes were measured.
Main Results:
- Normal ranges for knee angle and moment were determined across different walking speeds.
- Peak knee flexion moment showed a strong correlation with walking speed.
- Coronal plane knee angle was largely independent of walking speed.
- Stride length appears to be a reliable basis for defining normal ranges.
Conclusions:
- Walking speed significantly influences peak knee flexion moment.
- Coronal knee alignment during gait is less affected by walking speed.
- Stride length is a key factor in establishing normative gait data for clinical use.
