Description of intervention(s) / exposure
Brief name: Sense© for Kids

Procedures: Sense© for Kids addresses somatosensory discrimination functions through implementation of the following essential elements-
• Active exploration without vision of new and known stimuli where the child explores objects/textures/body positions with focus on discriminating differences.
• Anticipation is used for previously experienced stimuli; the child knows what to expect to feel and concentrates on attributes of difference without vision.
• Calibration occurs within and across modalities with comparison of what is felt by the impaired hand with the less affected hand and with vision. The child matches what they know from visual confirmation and calibration with the less affected hand with their impaired hand. They are prompted to imagine what the sensory stimulus is supposed to feel like based on this knowledge.
• Each level of stimulus difference is trained to an accuracy level of 75% correct responses before progressing to a more difficult level of difference.
• Transfer to untrained tasks is facilitated by training on a large variety of stimuli and integrating training principles into occupational tasks important the child. Occupational tasks are trained using grading of stimuli, feedback on distinctive features of difference and method of exploration. Additional information can be found in SENSe: A Manual for Therapists.
Carey L: SENSe: Helping stroke survivors regain a sense of touch: A Manual and DVD for therapists. Melbourne, VIC, Australia: Florey Institute of Neuroscience and Mental Health; 2012..

Who: Sense© for Kids will be administered by an occupational therapist with a minimum of 5 years experience.

Mode of delivery: Face to face individual therapy sessions.

Duration/ dose/ intensity: Children will receive three hours a week for six weeks amounting to 18 hours of total intervention. Two hours per week will be therapist-led, a cumulative one hour per week will be parent-led.

Location: In the participants home.

Tailoring: Because children will set their own goals, the activities pertaining to the goal itself may differ but in all other aspects this intervention will remain the same for all participants.

Fidelity: This study seeks to define and measure fidelity of Sense© for Kids for clinician adherence to the active ingredients and intervention receipt. A treatment fidelity checklist has been developed and will be published with the study protocol.

Brief name: Goal Directed Training via Home Programme

Procedures: Goal Directed Training via Home Programme addresses goal performance through implementation of the following essential elements-
Goal Directed Training essential elements:
- Caregiver and child set goals about real-life activities the child wants or needs to perform and determines with the therapist which are realistic for intervention.
- Examination of the goal-limiting factors at the child, task and environment level.
- Changing the task and environment to facilitate child-active independence task performance.
- Establishment of a child-active motor practice schedule based on current motor performance, including intense repetition, variation and structured feedback.
Home Program Essential Elements:
- Development of a collaborative partnership characterised by empowerment of parents
- Therapist takes on a coaching role in partnership with the parent as the expert in their unique context
- Goals are set by the child and parent
- A menu of tasks to practice using Goal Directed Training principles are provided to support home practice
- Therapists actively support implementation to ensure the program continues to meet family needs and help identify successes.

Who: Goal Directed Training via Home Programme will be administered by an occupational therapist with a minimum of 5 years experience.

Mode of delivery: Face to face individual therapy sessions.

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Allocation will involve central randomisation by online computer form by a staff member not involved with the study.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Dynamic (adaptive) random allocation methods such as Minimisation. Participants will be matched for age (+/- 6 months) and somatosensory capacity composite score to minimise the effect of heterogeneity in this population. When a participant is enrolled to the study without a match for age and somatosensory capacity, that child will be randomly allocated to a treatment group using an online randomisation form by a staff member not involved in the study. The next child enrolled who is a match for the unmatched participant will be automatically allocated to the alternate group. The process will be repeated for each matched pair; the first member always being allocated at random.

Statistical methods / analysis
To determine the sample size we used pilot data from seven children with HCP who received the intervention. Data from the Wrist Position Sense Test (a component of the sense©_assess_Kids) were entered into G* Power and a two tail “Means: difference between two independent groups” power calculation was performed. With an intervention group mean of 15.94 and standard deviation 9.72; and control group mean 25.79 and standard deviation 11.93 the calculated effect size was 0.9052. To detect this effect size, we need 42 subjects (21 in the intervention group and 21 in the control group) to have statistical power of 0.8 at the significance of 0.05. To account for attrition, this study will aim to enroll 50 children, with 25 in each of the control and intervention groups.

As outlined in the CONSORT statement reporting for RCT’s: between group comparisons will be conducted on intention to treat analysis. Missing data arising from incomplete observations and dropouts will be managed using multiple imputations. Multiple imputations is recommended for use in RCT’s because it avoids bias found in last observation carried forward approaches while maintaining power.
Summary statistics will be reported for each time point for each group using means and standard deviations. For skewed data, medians and interquartile ranges will be reported.

Somatosensory discrimination, goal performance and hand-use: A mixed-effects model with repeated measures will be used to assess within and between group differences. The corresponding baseline measure will be entered as a covariate in the model along with age and somatosensory capacity given these features were used in the randomisation process. The mixed model approach has the advantage of allowing for correlated data (repeated measures) and allows for missing observations within-subject. Model assumptions will be examined and if required transformations applied or non-parametric methods employed. Statistical significance will be set at 0.05.

Cortical change: First-level results from all participants will be pooled into an ANOVA, to investigate (A) changes by time-point, to search for an overall change in brain activation and (B) whether an interaction between time-point and treatment exists.
