Functional Assessment Questionnaire

Background Locomotor function is often impaired in children diagnosed with cerebral palsy (CP). Improving locomotor function is a common goal of treatment. The current gold standard for assessing locomotor function in CP is the gross motor function measure (GMFM-66). The GMFM-66 requires an in-person assessment by a trained clinician. It would be useful to have a measure of function that is like the GMFM-66 but can be assessed through patient report. Methods We queried the clinical databases of two motion analysis centers (Gillette Children's Specialty Healthcare and Shriners Hospital - Salt Lake City) for individuals with a diagnosis of cerebral palsy (CP) who were 18 years old or younger and had undergone instrumented clinical gait analysis that included the functional assessment questionnaire (FAQ). We computed the transformed FAQ (FAQt) as the weighted sum of the skills an individual was able to perform, where the weighting was the difficulty of the skills. We assessed concurrent and external validity of the FAQt by comparing it to the GMFM-66. Results The FAQt exhibited strong concurrent and external validity. Linear regression showed that the GMFM-66 explained 54% of the variance in FAQt, and the linear fit was independent of center. The FAQt evolved with age in a manner similar to the GMFM-66, with higher functioning individuals, as measured by gross motor function classification system level, achieving higher levels of function at a higher rate and an earlier age compared to their lower functioning peers. The findings with respect to GMFM-66 did not depend on the center at which the data was acquired. Conclusions The FAQt demonstrates strong concurrent and external validity, making it a useful measure of locomotor function

AbstractIntroductionConstraint-induced movement therapy (CIMT) improves upper limb (UL) motor execution in unilateral cerebral palsy (uCP). As these children also show motor planning deficits, action-observation training (AOT) might be of additional value. Here, we investigated the combined effect of AOT to CIMT and identified factors influencing treatment response.MethodsForty-four children with uCP (mean 9y6m, SD 1y10m) participated in a 9-day camp wearing a splint for 6 hours/day and were allocated to the CIMT+AOT (n=22) and the CIMT+placebo group (n=22). The CIMT+AOT group received 15 hours of AOT (i.e. video-observation) and executed the observed tasks, whilst the CIMT+AOT group watched videos free of biological motion and executed the same tasks. The primary outcome measure was bimanual performance. Secondary outcomes included measures at body function and activity level assessed before (T1), after (T2) the intervention, and at 6 months follow-up (T3). Influencing factors included behavioural and neurological characteristics.ResultsAlthough no between-groups differences were found (p>0.05), the addition of AOT led to higher gains in children with initially poorer bimanual performance (p=0.02). Both groups improved in all outcome measures after the intervention and retained the gains at follow up (p<0.01). Poor sensory function resulted in larger improvements in the total group (p=0.03) and high amount of mirror movements tended to result in better response to the additional AOT training (p=0.06). Improvements were similar irrespective of the type of brain lesion or corticospinal tract wiring pattern.ConclusionsAdding AOT to CIMT, resulted in better outcome for children with poor motor function and high amount of mirror movements. CIMT with or without AOT seems to be more beneficial for children with poor sensory function.Trial registrationRegistered at ClinicalTrials.gov on 22nd August 2017 (Identifier: NCT03256357).

Background. In many children with unilateral spastic cerebral palsy (USCP), the corticospinal tract to the affected hand atypically originates in the hemisphere ipsilateral to the affected hand. Such ipsilateral connectivity is on average a predictor of poor hand function. However, there is high variability in hand function in these children, which might be explained by the complexity of motor representations of both hands in the contralesional hemisphere. Objective. To measure the link between hand function and the size and excitability of motor representations of both hands, and their overlap, in the contralesional hemisphere of children with USCP. Methods. We used single-pulse transcranial magnetic stimulation to measure the size and excitability of motor representations of both hands, and their overlap, in the contralesional hemisphere of 50 children with USCP. We correlated these measures with manual dexterity of the affected hand, bimanual performance, and mirror movement strength. Results. The main and novel findings were (1) the large overlap in contralesional motor representations of the 2 hands and (2) the moderate positive associations of the size and excitability of such shared-site representations with hand function. Such functional associations were not present for overall size and excitability of representations of the affected hand. Conclusions. Greater relative overlap of the affected hand representation with the less-affected hand representation within the contralesional hemisphere was associated with better hand function. This association suggests that overlapping representations might be adaptively “yoked,” such that cortical control of the child’s less-affected hand supports that of the affected hand.
