Tm. Bach et al., COMPARISON OF SUBJECTIVE AND OBJECTIVE MEASURES OF MOVEMENT PERFORMANCE IN CHILDREN WITH CEREBRAL-PALSY, Developmental Medicine and Child Neurology, 36(11), 1994, pp. 974-979
This study evaluated the use of accelerometry to measure the quality o
f movement in children with cerebral palsy. Accelerometer scores based
on a previously described test were correlated with scores on a newly
developed clinical test shown to be both valid and reliable. Low corr
elations were obtained between clinical test scores and accelerometer
scores. Although the accelerometer test has been shown to be effective
in distinguishing between able-bodied children and those with cerebra
l palsy, it is not sufficiently sensitive to distinguish between level
s of movement quality in the latter population. The accelerometer may
measure a different aspect of movement from that measured by the clini
cal test, and does not appear to be a valid test of the quality of mov
ement in children with cerebral palsy.
