This study describes the reliability of a clinically oriented model for
three-dimensional movement analysis of head and trunk movements in children with
spastic diplegia. The model consists of five rigid segments (head, thorax,
pelvis, shoulder line, spine) and includes a detailed analysis of spinal
segmental movements. Within and between session reliability during gait was
tested in 10 children with spastic diplegia (6-14yrs).
Reliability of discrete
parameters was assessed with the intraclass correlation coefficient (ICC) and
similarity of thorax and pelvis waveforms with the coefficient of multiple
correlation (CMC). Measurement errors were calculated for all parameters (SEM,
sigma). Results indicated acceptable within and between session reliability of
discrete parameters for thorax, pelvis, shoulder line, angle of kyphosis and the
majority of the spinal segmental angles, reflected by low SEMs
(<4 degrees ) and
most ICCs>0.60. Within and between session waveform errors were below 4 degrees .
CMCs ranged from poor to very good, with highest values for movements in the
frontal and transversal planes. The angle of lordosis showed lower between
session reliability for several discrete parameters, although waveform errors
were still below 5 degrees . Head parameters showed lower overall reliability.
The results of this study support the reliability of the proposed model. Head
kinematic parameters should be interpreted with caution, due to difficulties in
standardization. Accurate palpation of the spinal markers, especially the lumbar
spine, is critical and demands thorough training of the assessor.
