Resistance Intensive Personal Training for Youth With Cerebral Palsy (RIPT)

Exploration of the Effectiveness and Feasibility of a Personalized Power Training Program for Youth With Cerebral Palsy Provided Through a Community-tertiary Hospital Partnership.

Changes related to Cerebral Palsy (CP) include differences in muscle architecture and cortical activity. These result in weakness, decreased functional ability and limited participation in physical activity. Strength training programs, particularly those including power training components, show great potential in improving the gross motor function of youth with CP. However, this intervention is not currently offered in the Calgary area. Delivered via an innovative partnership with community stakeholders, this project will investigate the preliminary effectiveness of the program to enable youth with CP to achieve child and family centered goals. It will also investigate the feasibility of offering this type of program via a community-hospital partnership. Research Question & Objectives: Can youth with cerebral palsy achieve their goals and improve their motor function through RIPT (Resistance Intensive Personal Training), a power training program offered jointly by specialized physiotherapists and fitness professionals in community settings? What are the barriers and facilitators to delivery of RIPT in a community setting for youth, caregivers, clinicians, and program staff?

What are the barriers and facilitators to delivery of RIPT in a community setting for youth, caregivers, clinicians, and program staff? Methods: We will conduct a mixed-methods experimental prospective cohort study. Two 12-week sessions of RIPT will be offered at the Mount Royal University community recreation centre and delivered in partnership by physiotherapists from Alberta Children's Hospital and community-based fitness professionals with additional support from students at Mount Royal University (training partners). Six youth with CP (aged 8-17, able to follow directions in English and exert a maximal effort with support) will participate in each session with 1:1 support for each participant's power training 1 hour/day, 2-3 days/week in a group setting. At recruitment potential barriers to regular attendance will be explored with an ACH Neurosciences Social Worker available to support as needed. Each participant and their family will generate individual goals using the Canadian Occupational Performance Measure and their individualized program will be tailored to target the movements and muscles needed to achieve each goal by physiotherapists trained in the RIPT protocol. This study is designed to evaluate if this practical implementation of the program is effective (i.e. can produce similar effect size as measured in randomized-controlled efficacy trials). Motor function will be measured with the gold-standard clinical scale in this population, Gross Motor Function Measure, and objective evaluation of muscle power using the isotonic mode on our Biodex Dynamometer. Both of these outcomes have established effect sizes. Further we will move the assessment approach to focus on the individual goals identified by the COPM as part of creating the training program by linking each one to the Goal Attainment Scale. For example, a participant's goal to be able to walk to the bus faster, can be objectively evaluated using a validated measure such as the 6-minute Walk Test. Changes in each of these objective outcomes can be prospectively mapped to the Goal Attainment Scale's ordinal rankings to enable repeated-measures analysis of outcomes based on those most salient to an individual. We will also use EQ-5DY to evaluate quality of life as comments from our pilot clinical program suggest the benefits were quite broad. These outcomes will be collected at baseline 8, and 12 weeks. The change between baseline and 12-weeks represents the key outcome to demonstrate effectiveness. Patient partners feel a shorter program would be more feasible for more participants and one previous study has shown efficacy at 8 weeks. Therefore, the 8-week time point will allow us to explore if participant goals can be met on this shorter timeline. Following training, youth and their families will complete the Measure of Processes of Care (MPOC 20) and participate in individual family focus-groups. Training partners will complete the Acceptability of Intervention Measure (AIM), Intervention Appropriateness Measure (IAM), and Feasibility of Intervention Measure (FIM) which are valid and reliable measures of implementation outcomes. We will also explore the barriers and facilitators to program delivery via semi-structured interviews with the training partners. Interviews will be anonymized and transcribed. Thematic analysis of the transcripts will assess each domain: barriers, facilitators, and perceived impacts of RIPT.

All participants will participate in this arm involving 12 weeks of training 2-3 days/week in a group setting with each session involving 1:1 support for each participant's power training.

Evidence based outcome measure designed to capture clients self-perception of performance in everyday living over time.

Individualized outcome measure involving goal selection and goal scaling that is standardized in order to calculate the extent to which a patient's goals are met.

Objective measure of muscle power using voluntary contractions based on muscles involved in goal setting for individual participants.
