Summary
Auditory cueing (AC) and visual cueing (VC) both create anti-correlated gait patterns. While AC and VC may use similar motor pathways for gait rehabilitation, VC significantly increases gait variability.
Area of Science:
- Human locomotion
- Biomechanics
- Gait analysis
Background:
- Sensorimotor synchronization of gait involves coordinating steps with rhythmic cues.
- Auditory cueing (AC) alters gait's fractal dynamics to anti-correlations.
- The impact of visual cueing (VC) on gait fluctuation patterns remains uninvestigated.
Purpose of the Study:
- To compare the effects of AC and VC on the fluctuation patterns of spatiotemporal gait parameters.
- To investigate how different cueing methods influence gait dynamics.
Main Methods:
- Thirty-six healthy individuals walked on an instrumented treadmill with augmented reality.
- Experimental conditions included no cueing (NC), auditory cueing (AC), and visual cueing (VC).
- Detrended fluctuation analysis and coefficient of variation (CV) assessed gait correlation structure and variability.
Main Results:
- Both AC and VC induced a significant anti-correlated pattern in gait parameters.
- CVs were similar between NC and AC conditions.
- VC substantially increased gait variability compared to NC and AC.
Conclusions:
- AC and VC likely engage similar motor control pathways, suggesting potential for alternative use in gait rehabilitation.
- VC's notable increase in gait variability requires careful consideration during therapeutic applications.
