This prospective multicenter study assessed performance and changes over
time, with and without surgical intervention, in the modified Timed Up and Go
(mTUG) and One-Minute Walk tests (1MWT) in children with bilateral cerebral palsy
(CP). Minimum clinically important differences (MCIDs) were established for these
tools. METHOD Two hundred and nineteen participants with bilateral spastic CP
(Gross Motor Function Classification System [GMFCS] levels I-III) were evaluated
at baseline and 12 months follow-up. The non-surgical group (n=168; 54 females,
114 males; mean age 12y 11mo, [SD 2y 7mo], range 8y 1mo-19y) had no surgical
interventions during the study. The surgical group (n=51; 19 females, 32 males;
mean age 12y 10mo [SD 2y 8mo] range 8y 2mo-17y 5mo) underwent soft-tissue and/or
bony procedures within 12 months from baseline. The mTUG and 1MWT were collected
and MCIDs were established from the change scores of the non-surgical group.
RESULTS Dependent walkers (GMFCS level III) required more time to complete the
mTUG (p</=0.01) than independent walkers (GMFCS levels I and II). For the 1MWT,
distance walked decreased with increasing impairment (p</=0.01). 1MWT and mTUG
change scores were not significantly different at any GMFCS level for either the
surgical or non-surgical groups (p</=0.01). INTERPRETATION Children with varying
levels of function (GMFCS level) perform differently on the 1MWT and mTUG. The
data and MCID values can assist clinicians in interpreting changes over time and
in assessing interventions.
