Assessment of gait abnormalities in cerebral palsy (CP) is challenging, and
access to instrumented gait analysis is not always feasible. Therefore, many
observational gait analysis scales have been devised. This study aimed to
evaluate the interobserver reliability, intraobserver reliability, and validity
of Edinburgh visual gait score (EVGS). Video of 30 children with spastic CP were
reviewed by 7 raters (10 children each in GMFCS levels I, II, and III, age 6-12
years). Three observers had high level of experience in gait analysis (10+
years), two had medium level (2-5 years) and two had no previous experience
(orthopedic fellows). Interobserver reliability was evaluated using percentage of
complete agreement and kappa values. Criterion validity was evaluated by
comparing EVGS scores with 3DGA data taken from the same video visit.
Interobserver agreement was 60-90% and Kappa values were 0.18-0.85 for the 17
items in EVGS. Reliability was higher for distal segments (foot/ankle/knee
63-90%; trunk/pelvis/hip 60-76%), with greater experience (high 66-91%, medium
62-90%, no-experience 41-87%), with more EVGS practice (1st 10 videos 52-88%,
last 10 videos 64-97%) and when used with higher functioning children (GMFCS I
65-96%, II 58-90%, III 35-65%). Intraobserver agreement was 64-92%. Agreement
between EVGS and 3DGA was 52-73%. We believe that having EVGS as part of the
standardized gait evaluation is helpful in optimizing the visual scoring. EVGS
can be a supportive tool that adds quantitative data instead of only qualitative
assessment to a video only gait evaluation.
