Background:
Critical threshold values of range of motion (ROM) during clinical
examinations of children with cerebral palsy (CP) have been implemented by
the Danish Cerebral Palsy Follow-up Program (CPOP) for the purpose of early
detection of restricted movements of joints and potential intervention.
Purpose / Aim of Study:
The aim of the present study was to test the hy-
pothesis that ROMmeasures in children with CP were associated with gait func-
tion by means of Gait Profile Score (GPS) and Gait Variable Score (GVS), and
to determine if ROM threshold values (red, yellow and green), influences gait
function.
Materials and Methods:
60 children with CP classified in GMFCS I- II, age
5-9 years, were included. Clinical examination of ROM of lower extremities was
performed according to procedures described by CPOP. Gait summary measures
(GPS and GVS), calculated through 3-dimensional gait analysis, were collected
at baseline from the CPinMOTION trial (ClinicalTrials.gov: NCT02160457).
Findings / Results:
Overall, the children demonstrated impaired gait function
(GPS: 10.5, IQR: 8.2-11.7). Weak associations were found between GVS and
ROM measures of clinical examination (r2= 0.19-0.25, p<0.05). Multiple re-
gression combining ROM of knee extension, hip extension and hip external ro-
tation explained 10.5 % of variance in gait. Differences in GVS between ROM
categories red vs. green were demonstrated in hip extension (p<0.05) and ankle
dorsiflexion with extended knee (p<0.05).
Conclusions:
Clinical examination of ROM demonstrated weak association with
gait summary measures in the present group of children with CP. Distinction of
the thresholds of ROM categories and the association with gait function may
be questioned and needs further examination, as an indication for intervention.
