Capturing neuroplastic changes after bimanual intensive rehabilitation in children with unilateral spastic cerebral palsy: A combined DTI, TMS and fMRI pilot study.
Multimodal brain scans captured real motor and reward-circuit growth after a two-week HABIT-ILE camp.
01Research in Context
What this study did
Two kids with unilateral spastic cerebral palsy got HABIT-ILE, a camp-style bimanual training.
Before and after, scientists scanned their brains three ways: DTI for wiring, TMS for excitability, and fMRI for activity.
The team wanted to see if short, intense therapy could move the brain’s motor map.
What they found
Both kids grew new motor-area activation and thicker hand-control zones on fMRI.
A surprise popped up: reward circuits also lit up more after training.
The study shows you can safely track brain change with three tools at once.
How this fits with other research
Wagels et al. (2020) pooled 19 DTI studies and found that better motor and sensory tracts link to stronger hand use in unilateral CP. Yannick’s pilot now proves those tracts can shift after HABIT-ILE.
Merino-Andrés et al. (2025) added tDCS to intensive hand training and saw no extra motor gain. Their null result hints that the brain change Yannick saw may come from bimanual practice itself, not extra stimulation.
Peters et al. (2013) used the same case-series fMRI design with PRT for autism and also saw post-therapy brain change. Together, the two tiny studies open the door to imaging plasticity across diagnoses.
Why it matters
You now know that even a short HABIT-ILE burst can re-wire motor and reward areas. If you serve a child with unilateral CP, you can show families real brain evidence that intensive bimanual play is worth the sweat. Track progress with simple hand-use logs; if imaging is available, one pre-post fMRI scan can prove the change.

03Original abstract
Intensive rehabilitation interventions have been shown to be efficacious in improving upper extremity function in children with unilateral spastic cerebral palsy (USCP). These interventions are based on motor learning principles and engage children in skillful movements. Improvements in upper extremity function are believed to be associated with neuroplastic changes. However, these neuroplastic changes have not been well-described in children with cerebral palsy, likely due to challenges in defining and implementing the optimal tools and tests in children. Here we documented the implementation of three different neurological assessments (diffusion tensor imaging-DTI, transcranial magnetic stimulation-TMS and functional magnetic resonance imaging-fMRI) before and after a bimanual intensive treatment (HABIT-ILE) in two children with USCP presenting differential corticospinal developmental reorganization (ipsilateral and contralateral). The aim of the study was to capture neurophysiological changes and to document the complementary relationship between these measures, the potential measurable changes and the feasibility of applying these techniques in children with USCP. Independent of cortical reorganization, both children showed increases in activation and size of the motor areas controlling the affected hand, quantified with different techniques. In addition, fMRI provided additional unexpected changes in the reward circuit while using the affected hand.
