ObjectiveDetermine the adherence to and effectiveness of an 8-week home exercise programme for children with disabilities delivered using Physitrack, an online exercise prescription tool, compared with traditional paper-based methods.DesignSingle-blinded, parallel-groups, randomised controlled trial (RCT).SettingIntervention took place in participants’ homes in Western Australia.ParticipantsChildren aged 6 to 17 years, with neurodevelopmental disabilities including cerebral palsy (CP), receiving community therapy services.InterventionAll participants completed an individualised home exercise programme, which was delivered to the intervention group using Physitrack and conventional paper-based methods for the control group.Primary outcome measuresAdherence to exercise programme, goal achievement and exercise performance.Secondary outcome measuresEnjoyment, confidence and usability of Physitrack.ResultsFifty-four participants with CP (n=37) or other neurodevelopmental disabilities (n=17) were recruited. Fifty-three were randomised after one early withdrawal. Forty-six completed the 8-week programme, with 24 in the intervention group and 22 in the control group. There was no difference between the two groups for percentage of exercises completed (intervention (n=22): 62.8% (SD 27.7), control (n=22): 55.8% (SD 19.4), between group mean difference −7.0% (95% CI: −21.6 to 7.5, p=0.34)). Both groups showed significant improvement in their self-rated performance of individualised goal activities, however there was no statistically significant difference between groups for goal achievement, quality of exercise performance, enjoyment, confidence or preferred method of delivery. There were no adverse events.ConclusionPhysitrack provides a therapist with a new means of providing an exercise programme with online tools such as exercise videos, but our preliminary findings indicate that it may be no better than a traditional paper-based method for improving exercise adherence or the other outcomes measured. Exercise programmes remain an intervention supported by evidence, but a larger RCT is required to fully evaluate online delivery methods.Trial registration detailsAustralian New Zealand Clinical Trials Registry; ACTRN12616000743460.

IntroductionChildren with cerebral palsy (CP) and other neurodevelopmental disabilities often receive a home programme of exercises to assist in reaching their therapy goals. Adherence to exercise programmes is necessary to attain the level of practice required to achieve goals; however, adherence can be difficult to accomplish. In this paper, we describe the protocol for a randomised controlled trial to evaluate the effectiveness of delivering a home exercise programme to school-age children with disabilities using Physitrack, an online exercise prescription tool with a website or app interface.Methods and analysisParticipants aged 6–17 years, with CP or other neurodevelopmental disabilities, receiving community physiotherapy services in Western Australia, will be recruited. Participants will be stratified by age and functional mobility and randomised to either the intervention group, who will complete an 8-week home exercise programme using Physitrack, or the control group, who will complete an 8-week exercise programme without Physitrack. Researcher blinding to group allocation, and participant blinding to outcome, will be maintained. The primary outcome measures are adherence to the home exercise programme with weekly collection of home exercise logs; achievement of individualised goals by phone interview before and after intervention; and correctness of exercise performance by collection and analysis of videos of participants performing home exercises. Secondary outcome measures include enjoyment of physical activity, confidence to complete exercise programme, preferred method of delivery of programme and usability of Physitrack. A sample size of 58 participants will be necessary to see an effect on home programme adherence. Data will be analysed using the intention-to-treat principle.Ethics and disseminationEthical approval was obtained from Curtin University Human Research Ethics Committee in July 2016 (10391). Outcomes will be disseminated through publication in peer-reviewed journals and presentations at scientific conferences.Trial registration numberACTRN12616000743460; Pre-results.

Background Mobile health (mHealth) apps for children are increasing in availability and scope. Therapy (physiotherapy, speech pathology, and occupational therapy) prescription apps to improve home or school program adherence work best when developed to be highly engaging for children and when they incorporate behavior change techniques (BCTs) within their design. Objective The aim of this study was to describe the development of a user-centered therapy prescription app for children (aged 6-12 years) with neurodevelopmental disabilities (eg, cerebral palsy, autism spectrum disorder, and intellectual disability) incorporating intervention mapping (IM) and gamified design. Methods We used an iterative, user-centered app development model incorporating the first 3 steps of IM. We conducted a needs analysis with user feedback from our previous mHealth app study, a literature review, and a market audit. Change objectives were then specified in alignment with the psychological needs of autonomy, competence, and relatedness identified in self-determination theory. From these objectives, we then selected BCTs, stipulating parameters for effectiveness and how each BCT would be operationalized. A gamification design was planned and implemented focusing on maximizing engagement in children. In total, 2 rounds of consultations with parents, teachers, and therapists and 1 round of prototype app testing with children were conducted to inform app development, with a final iteration developed for further testing. Results The IM process resulted in the specification of app elements, self-determination theory–informed BCTs, that were embedded into the app design. The gamification design yielded the selection of a digital pet avatar with a fantasy anime visual theme and multiple layers of incentives earned by completing prescribed therapy activities. Consultation groups with professionals working with children with disabilities (4 therapists and 3 teachers) and parents of children with disabilities (n=3) provided insights into the motivation of children and the pragmatics of implementing app-delivered therapy programs that informed the app development. User testing with children with disabilities (n=4) highlighted their enthusiasm for the app and the need for support in the initial phase of learning the app. App quality testing (Mobile Application Rating Scale-user version) with the children yielded means (out of 5) of 4.5 (SD 0.8) for engagement, 3.3 (SD 1.6) for function, 3.3 (SD 1.7) for aesthetics, and 4.3 (SD 1.1) for subjective quality. Conclusions mHealth apps designed for children can be greatly enhanced with a systematic yet flexible development process considering the specific contextual needs of the children with user-centered design, addressing the need for behavior change using the IM process, and maximizing engagement with gamification and strong visual design.
