The purposes of this study were to construct a real-time acceleration
gait analysis system equipped with software to analyse real-time trunk
acceleration during walking and to examine the intra-rater and inter-rater
reliabilities of the this system. This system has been comprised of an
accelerometer, an acceleration amplifier, a transmitter, two foot switches, a
receiver and a personal computer installed with the real-time acceleration
analysis software.
The acceleration signals received were analysed using the
real-time acceleration analysis software, and gait parameters were calculated.
The subjects were 20 healthy individuals and two raters.
The intra-rater and
inter-rater reliabilities of the measurement results obtained from this system
were examined by performing intraclass correlation coefficients (ICC) and
Bland-Altman analysis. RESULTS: The intra-rater and inter-rater ICCs ranged from
0.61 to 0.92 in any gait parameters. In the Bland-Altman analysis, neither fixed
nor proportional bias was found in any of the gait parameters. CONCLUSIONS: From
the ICC and Bland-Altman analysis results, the gait measurement using this system
clearly demonstrates that the intra-rater and inter-rater measurements had good
reproducibility. Owing to this system, we can improve the clinical efficiency of
gait analysis and gait training for physiotherapy. Implication for Rehabilitation.
This study focused on the advantage of a gait analysis method using an
accelerometer and constructed a gait analysis system that calculates real-time
gait parameters from trunk acceleration measurements during walking. The gait
analysis using this system has good intra-rater and inter-rater reliabilities,
and using this system can improve the clinical efficiency of gait analysis and gait training.
