Description of intervention(s) / exposure
HABIT-ILE is a motor learning approach simultaneously addressing coordination of the upper and lower limbs. Key elements of HABIT-ILE are:

Dose: 30 hours of therapy achieved through a 2-week intensive group-delivered model for 3 hrs/day over 10 days in addition to a home program for generalization of learning. Home program dose will aim to achieve a further 10 hours over the two week intervention period for a total dose of preschool HABIT-ILE of 40 hours.

Mode: Groups of 4-6 children (1:1 or 2:1 therapist:child ratio according to ability).

Content and tailoring: The intervention will be based on the child’s motor abilities (determined at baseline), age, interests and caregiver-identified functional goals. Tasks/activities are made incrementally more challenging. Practice will be embedded in play, using part and whole task practice with high repetition including (i) table top fine motor play-based activities; (ii) activities of daily living when sitting/standing/walking; and (iii) gross motor play. Lower extremity motor abilities and postural control will be progressed from lying to sitting on the floor and then to a small bench, and transitions between floor to sitting, sitting to standing.

Intervention providers: Physiotherapists and occupational therapists, who have completed standardized training and are experienced in delivering HABIT-ILE with older children. A speech pathologist will consult with the team if children have specific communication (receptive and/or expressive) or feeding difficulties.

The level of intensity (e.g. low, moderate, vigorous) and how this is assessed: Low to vigorous. Will vary across the intervention session. Children will be wearing polar heart rate monitors during the intervention sessions.

Strategies used to assess or monitor participant adherence to the intervention, (e.g. session attendance checklists, diary, etc) : Daily sign on/off sheets for caregivers, daily activity log detailing activities throughout course of session completed by one of treating therapists.

For 30 minutes, at the conclusion of each session, the child’s treating therapists will meet individually with the child’s caregiver/s (one-on one) and discuss the daily program and make suggestions about activities that could be practised at home. These will be detailed on a written home program form and will include a home practice log completed by the caregiver. The home program activities will be reviewed daily by the child’s treating therapist in collaboration with the child’s caregiver and updated as appropriate. Parents will be able to take short videos/photos of home practice activities on their smart phone if they wish so to have a visual reminder to take home. Location: Centre for Children’s Health Research and QCH, South Brisbane.

Fidelity: Standardised therapist training will be provided to therapists employed to deliver the intervention. The training package will include an intervention manual and onsite training during the first Preschool HABIT-ILE camp lead by a master trainer

Comparator / control treatment
Usual care over the six month wait-list period will vary for children with CP and can range from weekly clinic-based therapy sessions to school-based consultative services provided on a monthly, quarterly or yearly basis. In order to understand the variability in usual care received, all families in both groups will complete a usual care diary for the duration of study involvement. The diary (via an APP) will record the frequency and duration of physiotherapy, and occupational therapy and any other concurrent medical interventions such as intramuscular Botulinum Toxin A injections and/or serial casting. All children in the control group will be offered Preschool HABIT-ILE commencing at the the 6 month retention time point (T3).

Outcomes
Primary outcome [1] 321975 0
Objective assessment of fine and gross motor skills
The Peabody Developmental Motor Skills (PDMS-2) will evaluate gross and fine motor skills. This standardised, norm reference measure for children from birth to 5 years of age, has been validated as a discriminative measure, and demonstrated responsiveness to change for toddlers with CP.
Timepoint [1] 321975 0
Baseline measures will be taken between 1-3 weeks prior to the intervention (T0). Primary outcome at Primary End-Point (T2) within 1-2 weeks following the 2 week intervention program and; retention (T3) at 6 months post intervention
Secondary outcome [1] 376889 0
Bimanual Hand Performance
Both Hands Assessment measures how children with bilateral CP use their hands together in bimanual activities. Rasch measurement modelling showed strong evidence of internal construct validity, with two separate item difficulty hierarchies for children with: (a) symmetric upper limb use; (b) asymmetric upper limb use. The test uses a selection of toys to elicit bimanual hand behaviour in a structured play session. The BoHA takes minutes to complete.

Self-Care Paediatric Evaluation of Disability Inventory Computer Adapted Test (PEDI-CAT) is a Rasch analysed parent completed questionnaire which measures ability in functional domains of self-care, mobility, social/cognitive and responsibility using normative standard scores and scaled scores with good validity, reliability, and standardisation with typically developing children. The 'content-balanced' ” will be used because the test developers advised that this version is more suitable for research purposes. This change was made prior to recruitment commencing.

COPM Performance of occupational performance goals.
The Canadian Occupational Performance Measure (COPM) will be used to measure performance of and satisfaction with individually defined self-care, leisure or productivity goals. Test retest reliability is high (ICC 0.76-0.89) and the COPM is responsive to change. Children and their caregivers will set up to three goals. Perceived performance of an individualized goal and satisfaction with performance is rated on a 1-10 scale with higher scores reflecting higher perceived performance and satisfaction.

Objective physical activity
Assessed via The ActiGraph GT3X+ (a triaxial accelerometer housed inside a watch-sized device). ActiGraph GT3X+ accelerometry is valid and feasible to detect and quantify objective bimanual performance in children with CP. One ActiGraph GT3X+ will be worn on each wrist, one additional ActiGraph GT3X+ will be worn on the less-affected ankle, and one Polar OH1 Optical HR Monitor will be worn on one upper arm during PDMS-2, BoHA, and GMFM-88 assessments. Two ActiGraphs only (1 less-affected ankle, 1 less-affected wrist) will also be worn for 7 days during all waking hours at each timepoint to assess daily habitual physical activity.

Statistical methods / analysis
Dr Mark Chatfield, Biostatistician, will provide expert advice for guiding and assisting with the analysis. Analyses will follow standard principles for RCTs using two-group comparisons on all participants on an intention-to-treat basis. Imputation techniques will avoid bias as a consequence of non-ignorable missing data during follow up. Primary comparison immediately post intervention (T2) based on PDMS-2 Total Motor Quotient scores will be between treatment groups using linear regression with treatment group (HABIT-ILE/waitlist) included as the main effect and baseline PDMS-2 Motor Quotient as the covariable. Effect estimates will be presented as mean difference and 95% confidence interval. Secondary analyses will use similar methods to compare outcomes between groups immediately post intervention (T2) for gross motor function, bimanual hand function, self-care and performance of and satisfaction with individualised goals. In cases where interval data are not able to be transformed appropriately for regression analyses, non-parametric methods (Mann-Whitney U) will be used for between-treatment comparisons. Possible differential attrition will be assessed by comparing baseline characteristics of drop-outs and continuing participants using t-tests (or Mann-Whitney U) for continuous variables and chi-squared tests for categorical variables. Sensitivity analyses of all outcomes will be conducted using multiple imputation techniques, to investigate the effect of non-ignorable missing data during follow up.
