ABSTRACT
Objective To explore the extent of agreement between measurements of temporal and spatial gait parameters made with portable gait analysis equipment and in the laboratory.Methods Fifteen healthy young people submitted to laboratory gait analysis using 3D motion analysis apparatus and then on the same day to analysis using the Gait Watch portable apparatus.Cadence,stride length,walking speed and step length were recorded.Intraclass correlation coefficients (ICCs) and Bland-Altman plots were used to evaluate the agreement between the two gait analyses.Results Test-retest comparisons with the Gait Watch apparatus generated ICCs for the temporal and spatial parameters ranging between 0.80 and 0.98,indicating good test-retest reliability.Bland-Altman plots comparing the two measurement systems also showed good agreement.According to paired simple t tests,the stride length,walking speed,and step length assessments with the two systems showed significant differences.All exceeded the minimum detection threshold (stride length =0.05 m,walking speed =0.12 m/s,left step length =0.03 m,right step length =0.04 m).Conclusions Measurements of cadence,stride length,walking speed and step length with the two systems yield acceptable agreement,and either can be used in clinical walking assessment.
