The aim of this study was to determine the effect of using video analysis
software on the interrater reliability of visual assessments of gait videos in
children with cerebral palsy.
Two clinicians viewed the same random selection of
20 sagittal and frontal video recordings of 12 children with cerebral palsy
routinely acquired during outpatient rehabilitation clinics. Both observers rated
these videos in a random sequence for each lower limb using the Observational
Gait Scale, once with standard video software and another with video analysis
software (Dartfish((R))) which can perform angle and timing measurements. The
video analysis software improved interrater agreement, measured by weighted
Cohen's kappas, for the total score (kappa 0.778-->0.809) and all of the items
that required angle and/or timing measurements (knee position mid-stance kappa
0.344-->0.591; hindfoot position mid-stance kappa 0.160-->0.346; foot contact
mid-stance kappa 0.700-->0.854; timing of heel rise kappa 0.769-->0.835). The use
of video analysis software is an efficient approach to improve the reliability of
visual video assessments.
