Samenvatting
Introduction: Quantifying the parameters of gait is usually a complex task for researchers and therapists. There have been various techniques employed over the years to assess the parameters of gait such as visual observation, paper walk way and many more. In recent years, the GAITRite® system has become popular and is frequently used to quantify the parameters of gait as well as setting baseline for clinicians. Studies have shown that the GAITRite® system is a valid instrument for assessing gait parameters; however, there has been limited research performed studying the reliability of the system using large number of participants. The purpose of this study is therefore to assess the test-retest reliability of the GAITRite® system on healthy adults.
Method: A total number of 179 subjects participated in this study of which 74 were male while 105 were female. The participants of this study were first year physiotherapy students of the Hanze University of Applied Sciences Groningen. The participants were tested in the Hanze active ageing lab (HAAL) using the GAITRite® system. Twelve temporal and spatial gait parameters were assessed; these included velocity, cadence, step time, step length, cycle time, stride length, swing time, stance time, toe in/toe out, heel to heel base of support, single support time and double support time.
Result: The mean age of the 179 subjects was 20 (range 18-28, SD: 2.0). From the evaluated gait parameters heel to heel base of support showed a strong correlation of r=0.79, the single support time as well as the double support time both showed an excellent correlation of r=0.91 while these three were also significant at P<0.05. All the other selected temporal and spatial gait parameters showed a weak correlation with r<0.30 as well as showing varying significance.
Conclusion: This study has shown the GAITrite system to be reliable in assessing three of the twelve selected parameters of gait namely heel to heel base of support, single support time and double support time while demonstrating a poor reliability in the other selected parameters of gait.
