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.

The Impact

ABSTRACTBackgroundMirror movements (MM) influence bimanual performance in children with unilateral cerebral palsy (uCP). Whilst MM are related to brain lesion characteristics and the corticospinal tract (CST) wiring pattern, the combined impact of these neurological factors remains unknown.ObjectiveTo investigate the combined impact of neurological factors on MM.MethodsForty-nine children with uCP (mean age 10y6mo) performed a repetitive squeezing task to quantify similarity between MM activity (MM-similarity) and strength of the MM activity (MM-intensity). We used MRI to evaluate lesion type (periventricular white matter, N=30) cortico-subcortical, N=19), the extent of ipsilesional damage and damage to basal ganglia, thalamus and corpus callosum. The CST wiring pattern (17 CSTcontralateral, 16 CSTipsilateral, 16 CSTbilateral) was assessed with Transcranial Magnetic Stimulation. Data was analyzed with simple and multiple regression analyses.ResultsMM-similarity in the more-affected hand was higher with more damage to the corpus callosum. MM-intensity was higher in children with CSTcontralateral with damage to the basal ganglia and thalamus. In the less-affected hand, MM-similarity was explained by the interaction between lesion type and CST wiring pattern, with higher MM-similarity in children with cortico-subcortical lesions in the CSTcontralateral group. MM-intensity was higher with larger damage to the corpus callosum and unilateral lesions.ConclusionsA complex combination of neurological factors influences MM characteristics and the mechanisms differ between hands.
