Status Recruiting

Clinical Trial Summary

The main aim of this project is to gain knowledge about the muscle-tendon pathology of moderately to severely affected young people with cerebral palsy and their risk for cardiometabolic diseases and chronic inflammation. Furthermore, it will be investigated whether there are associations between the existing pathophysiology as well as inactivity and muscle function, cardiometabolic risk factors and inflammation. Moreover, the potential of the target group for adaptation of its muscular, cardiorespiratory, and endocrine system will be investigated. The study parameters will be determined in adolescents and young adults aged 14 to 25 years with moderate to severe spastic cerebral palsy and compared with those of their less severely affected and healthy peers (cross-sectional study). In addition, the more affected individuals will participate in a 12-week training intervention (longitudinal study) performed with special tricycles (i.e., Frame Runners). To measure the study parameters, ultrasound, strength tests, near-infrared spectroscopy, blood analyses, and spiroergometry will be used. The fitness training will be performed two times a week for 12 weeks with the Frame Runners.

Clinical Trial Description

Background: Spastic cerebral palsy (CP) is a neuro-developmental disorder in children. Although the initial brain injury is not progressive, muscle pathology, a leading sign in affected individuals, is an on-going process. Individuals with CP are less physically active compared to their typically developing (TD) peers and severely affected individuals are most sedentary. Therefore, increased muscle wasting, decreased muscle function and cardiorespiratory fitness, metabolic dysregulation, and chronic low-grade inflammation might exist in the latter group. However, information is scarce and the role of muscle-tendon pathology and physical inactivity remains to be elucidated. Finally, it is unknown whether their tissues and organs may still adapt to health-inducing stimuli. Objectives: The main project aims are 1) to enhance our understanding of spastic muscle-tendon pathology, risk of cardiometabolic disease, and chronic inflammation likely present in young people with more severe spastic CP, and 2) to uncover the relationship of muscle-tendon alterations and physical inactivity on muscle function and metabolism as well as cardiometabolic risk factors and systemic inflammation. Moreover, the potential for adaptation of their muscular, cardiorespiratory, and endocrine system will be investigated. Methods: A cross-sectional study will be performed to compare severely impaired adolescents and young adults with spastic CP, their mildly affected CP and TD peers. The former group will further participate in a 12-week cardiorespiratory fitness training with Frame Runners. Muscle-tendon properties will be examined using ultrasound and shear wave elastography, and muscle function and metabolism with dynamometry and near infrared spectroscopy. Blood samples will be analyzed assessing metabolic parameters, and pro-inflammatory cytokines. Cardiorespiratory fitness will be investigated using the 6-Minute Frame Running Test and gas exchange analysis. Physical activity will be evaluated with accelerometers and activity diaries. Mental well-being and quality of life will be assessed by use of the CPCHILD™ questionnaire. ;
