This study aimed to quantify the inter- and intrarater clinician agreement
on joint motion patterns in children with spastic cerebral palsy (CP), which were
recently specified by a Delphi consensus study.
It also examined whether
experience with three-dimensional gait analysis (3DGA) is a prerequisite for
using the patterns. METHOD: The experimental group consisted of 82 patients with
CP (57 males, 25 females; uni-/bilateral CP [n=27/55];
Gross Motor Function
Classification System levels I to III; mean age 9y 5mo [range 4y-18y]).
Thirty-two clinicians were split into 'experienced' and 'inexperienced' rater
groups. Each rater was asked to classify 3DGA reports of 27 or 28 patients twice.
Inter- and intrarater agreement on 49 joint motion patterns was estimated using
percentage of agreement and kappa statistics. RESULTS: Twenty-eight raters
completed both classification rounds. Intrarater agreement was 'substantial' to
'almost perfect' for all joints (0.64<k<0.91). Interrater agreement reached
similar results (0.63<k<0.86), except for the knee patterns during stance
(k=0.49, 'moderate agreement'). Experienced raters performed significantly better
on patterns of the knee during stance and ankle during swing. INTERPRETATION:
Apart from some specific knee patterns during stance and ankle patterns during
swing, the results suggested that clinicians could use predefined joint motion
patterns in CP with good confidence, even in case of limited experience with 3DGA.
