Eligibility
Inclusion criteria
Inclusion criteria: • diagnosis of bilateral spastic CP, lower limbs more involved than the upper limbs;* • 8-14 years; • GMFCS level 2;* • able to stand independently for 2 min; • Child and Parent/guardian consent; • Sufficient cooperation & cognitive skills: able to follow simple instructions & complete the measurements. • MRI can be performed without general anesthesia. * criteria for children with CP, not for the typically developing control children.
Exclusion criteria
Exclusion criteria: • orthopaedic surgery or other surgery in the past twelve months that might influence mobility; • Botulinum Toxin A injections in the past six months; • Selective dorsal rhizotomy (SDR) in the past year; • Vestibular deficits, benign vertigo or unstable epilepsy; • Claustrophobia; • Pacemaker or other non-removable magnetic metal-containing objects; • Not able to lie still for the duration of the scan; • Not willing to hear about ‘incidental findings’, potential unforeseen, clinically relevant abnormalities found in the MRI images
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The Pediatric Balance Scale (PBS) will be evaluated as the main outcome of balance control. | — |
Secondary
| Measure | Time frame |
|---|---|
| Additional balance control measures, such as: 1. ‘balance’ and ‘running speed and agility’ subtest of the Bruininks-Oseretsky Test of Motor Proficiency 2. Trunk Control Measurement Scale 3. Sensory Organization Test 4. Spatio-temporal and kinematic gait parameters during unperturbed and perturbed walking 5. Maximum Lyapunov Exponents 6. Gait sensitivity Norm 7. Foot Placement Estimator Magnetic Resonance Imaging (MRI) measures of the brain, such as: 1. structural brain Magnetic Resonance Imaging scans (T1 & FLAIR) 2. Diffusion tensor imaging scans 3. resting-state functional MRI scans | — |
