abstract = "BACKGROUND: Girls and women with Rett Syndrome (RTT) have low levels of daily physical activity and high levels of sedentary time. Reducing sedentary time and enhancing {"}uptime{"} activities, such as standing and walking, could be an important focus for interventions to address long-term health and quality of life in RTT. OBJECTIVE: The aim of the study was to evaluate the feasibility and health-related effects of an individualized 12-week uptime participation (U-PART) intervention in girls and women with RTT. DESIGN: The study used a single-group pretest-posttest design with 4 assessments (2 baseline, postintervention, and follow-up). METHODS: A participation-based intervention employing a whole-day approach was used. During a 12-week intervention period, individualized programs focused on participation in enjoyable uptime activities in home, school/day center, and community settings. Feasibility was assessed with a study-specific questionnaire. Primary outcome measures were sedentary time and daily step count. Secondary outcomes were gross motor skills, walking capacity, quality of life, and goal attainment scaling. RESULTS: Fourteen girls and women who were 5 to 48 years old and had RTT participated. The U-PART intervention was perceived as feasible by caregivers. Similar scores were observed at baseline assessments in all outcomes. Positive effects with small to medium effect sizes (0.27-0.54) were seen in sedentary time (- 4%), daily step count (+ 689 steps/d), walking capacity (+ 18.8 m), quality of life (+ 2.75 points), and goal attainment scaling after the intervention. Positive effects were maintained in sedentary time (- 3.2%) and walking capacity (+ 12.1 m) at short-term follow-up. LIMITATIONS: This study was limited by the lack of a control group. However, participants acted as their own control, and the stable baseline period partially mitigated this issue. CONCLUSIONS: The U-PART intervention was found to be feasible and effective in the short term in girls and women with RTT.",
