Physical Activity Intervention for MPS
An observational study of Mucopolysaccharidosis (MPS), run by Brunel University at 1 site in United Kingdom.
Trial summary
Currently, treatments for mucopolysaccharidoses (MPS) are pharmacological and predominantly focus on the physical symptoms of the disease.

About this study
Official title: Co-design of a Physical Activity and Sedentary Behaviour Intervention for Adults With Mucopolysaccharidosis
Currently, treatments for mucopolysaccharidoses (MPS) are pharmacological and predominantly focus on the physical symptoms of the disease. In the general population and individuals with disabilities, increasing physical activity levels and reducing sedentary time can be an effective, non-pharmacological treatment to improve mental health and quality of life. Such interventions have not yet been developed or evaluated in people with MPS.
The aim of this study is to co-design a physical activity and sedentary behaviour intervention tailored to the needs of adults with MPS. The study will seek to gain the expertise of adults with MPS, specialist stakeholders (physicians and clinical nurse specialists) and lay specialist stakeholders (family and friends of adults with MPS and members of staff and volunteers at the Society for Mucopolysaccharide Diseases). A range of views and experiences of physical activity and sedentary behaviour will be explored via focus groups (with individuals with MPS and lay specialist stakeholders) and semi-structured interviews (with specialist stakeholders). The information gathered from the focus groups and interviews will then be utilised to inform participatory workshops (with individuals with MPS) to test intervention concepts. Data from these activities will inform the design of a future intervention.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Currently, treatments for mucopolysaccharidoses (MPS) are pharmacological and predominantly focus on the physical symptoms of the disease. In the general population and individuals with disabilities, increasing physical activity levels and reducing sedentary time can be an effective, non-pharmacological treatment to improve mental health and quality of life. Such interventions have not yet been developed or evaluated in people with MPS.
The aim of this study is to co-design a physical activity and sedentary behaviour intervention tailored to the needs of adults with MPS. The study will seek to gain the expertise of adults with MPS, specialist stakeholders (physicians and clinical nurse specialists) and lay specialist stakeholders (family and friends of adults with MPS and members of staff and volunteers at the Society for Mucopolysaccharide Diseases). A range of views and experiences of physical activity and sedentary behaviour will be explored via focus groups (with individuals with MPS and lay specialist stakeholders) and semi-structured interviews (with specialist stakeholders).
