Summary
Fixating pelvic translations in horizontal plane during gait training alters natural walking. This pelvic fixation significantly impacts step width, step length, and trunk rotations, affecting gait dynamics.
Area of Science:
- Biomechanics
- Neuro-rehabilitation Engineering
- Human Motion Analysis
Background:
- Assistive devices in neuro-rehabilitation can restrict natural human motion.
- Restricted motion may impact the normality of gait during training.
Purpose of the Study:
- To determine the effects of fixating pelvic translations in the horizontal plane on gait during treadmill walking.
- To analyze how pelvic fixation influences gait parameters and external forces.
Main Methods:
- Direct measurement of pelvic motion and external forces.
- Gait descriptors including step parameters, trunk angles, and ground reaction force parameters were measured.
- Experiments were conducted at varying gait velocities (0.35, 0.60, and 0.90 m/s).
Main Results:
- Pelvic fixation reduced step width by 33% and increased step length by 19%.
- Sagittal and coronal trunk rotations changed by +68% and -54%, respectively.
- Pelvic fixation significantly altered the effect of walking speed on most gait descriptors.
Conclusions:
- Fixating pelvic translations in the horizontal plane severely affects gait dynamics.
- Such fixation should be avoided during neuro-rehabilitation training to ensure natural walking patterns.
