'Uptime' Participation Intervention in Girls and Women With Rett Syndrome

Study Overview
=================
Brief Summary
-----------------
The aim of the study is to evaluate the feasibility and health-related effects of an individualized 12wk 'uptime' participation intervention in girls and women with Rett syndrome. Girls and women above 5 years of age with Rett syndrome and a confirmed MECP2 mutation will be included. Each individual program focuses on participation in enjoyable activities to promote 'uptime' in home, school/day center and community settings. Primary outcomes are sedentary time and daily steps. Secondary outcomes are gross motor skills, walking capacity, quality of life and participation-level goals. Outcomes are evaluated on four occasions: at baseline and after a 6-week interval, immediately following the 12-week intervention program and 12 weeks after the intervention program.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: UPART intervention group<br>A 1-group pretest-posttest design was conducted. Outcomes were evaluated on four occasions; twice during baseline separated by six weeks and immediately following a 12-week 'uptime' participation intervention and after a further 12 weeks (follow-up). | Other: 'Uptime' participation<br>* The intervention are designed for each individual and are consistent with the model for participation-based interventions. The interventions are goal-oriented (meaningful and family/client-selected goals), family/client-centered (promoted self-determination and decision making), collaborative (partnership between caregivers), strength-based (built on participant and caregiver strengths) and ecological (natural environment and real-life experiences). Design of the intervention comprised three steps: 1) Preparation period (6 weeks); 2) Intervention period (12 weeks); 3) Follow-up period (12 weeks)<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| ActivPAL | Change in sedentary time | Assessed four times; twice at baseline; once after the 12 week intervention and once after a further 12 week follow-up | 
| Stepwatch Activity Monitor | Change in daily step count | Assessed four times; twice at baseline; once after the 12 week intervention and once after a further 12 week follow-up | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Rett Syndrome Gross Motor Scale | Change in gross motor skills | Assessed four times; twice at baseline; once after the 12 week intervention and once after a further 12 week follow-up | 
| 2 minute walk test | Change in walking capacity | Assessed four times; twice at baseline; once after the 12 week intervention and once after a further 12 week follow-up | 
| Quality of Life Inventory - Disability, questionnaire | Change in quality of life. The Quality of Life Inventory-Disability was used to assess quality of life. This 32 item-questionnaire was developed for children 5-18 years of age with ID. Responses are used to calculate an overall score and six subscale scores (social interaction, positive emotions, physical health, negative emotions, leisure/outdoors and independence), each scored on a 0-100 scale with higher scores representing better quality of life. | Assessed four times; twice at baseline; once after the 12 week intervention and once after a further 12 week follow-up | 
| Goal attainment scaling | Change in participation level goals. Goal attainment scaling is a validated method for evaluating achievement of individual goals. Individual goals were assessed on a five-point rating scale ranging from -2 to +2. Baseline was set at -2, the expected level after the intervention at zero and the most favorable outcome at +2. The goals were graded in relation to frequency or duration of an activity. | Assessed twice; at baseline and after the 12 week intervention |
