Aim:
To evaluate the reliability, validity and responsiveness of the High-level Mobility Assessment Tool (HiMAT) in children and adolescents with traumatic brain injury (TBI) and to compare the mobility skills of children with TBI to those of healthy peers.
Method:
The mobility skills of 52 children with moderate and severe TBI (36 males; mean age = 12 years, range = 6-17) were assessed using the HiMAT and the Pediatric Evaluation of Disability Inventory (PEDI). Inter-rater reliability, re-test reliability and responsiveness of the HiMAT were evaluated in sub-groups by comparing results scored at several time-points. The HiMAT scores of children with TBI were compared with those of a healthy comparative cohort.
Results:
The HiMAT demonstrated excellent inter-rater reliability (ICC = 0.93), re-test reliability (ICC = 0.98) and responsiveness to change (p = 0.002). The PEDI demonstrated a ceiling effect in mobility assessment of ambulant children with TBI. The HiMAT scores of children with TBI were lower than those of their healthy peers (p < 0.001).
Interpretation:
The HiMAT is a reliable, valid and sensitive measure of high-level mobility skills following childhood TBI. The high-level mobility skills of children with TBI are less proficient than their peers.
