Summary
This study used trunk accelerometry to analyze stroke patient gait, finding that normalized RMS values effectively differentiate stroke survivors from healthy individuals and correlate with motor recovery.
Area of Science:
- Biomechanics
- Rehabilitation Medicine
- Medical Instrumentation
Background:
- Stroke frequently impairs gait, necessitating objective measures for assessing recovery.
- Trunk accelerometry offers a potential method for quantifying gait characteristics.
Purpose of the Study:
- To characterize stroke patient gait using trunk acceleration signals.
- To evaluate the correlation between gait parameters, functional recovery, and acceleration metrics.
- To determine the validity of accelerometry in assessing gait in stroke survivors.
Main Methods:
- Sixty-three stroke patients and 21 healthy elderly controls walked at a self-selected pace.
- A wireless tri-axial accelerometer measured trunk acceleration at the L3 level.
- Gait parameters, functional recovery, and acceleration metrics (RMS, normalized RMS, AC) were analyzed.
Main Results:
- Stroke patients exhibited significantly lower raw RMS and AC values than controls (p<0.01).
- Stroke patients showed significantly higher normalized RMS values compared to controls (p<0.05).
- Normalized RMS correlated with gait smoothness, motor recovery, and functional abilities.
Conclusions:
- Accelerometry-derived gait parameters can effectively discriminate between stroke patients and healthy individuals.
- Normalized RMS of trunk acceleration is a valid objective measure for assessing walking movements and treatment outcomes in stroke rehabilitation.
