Oppewal, Alyt; Festen, Dederieke A. M.; Hilgenkamp, Thessa I. M. – American Journal on Intellectual and Developmental Disabilities, 2018
Gait is a relevant and complex aspect of motor functioning. Disturbances are related to negative health outcomes. Gait characteristics of 31 adults with intellectual disability (ID) without Down syndrome (DS) (42.77 ± 16.70 years) were investigated, and associations with age, sex, body mass index (BMI), and level of ID were assessed. Sex and BMI…

Raspa, Melissa; Bann, Carla M.; Gwaltney, Angela; Benke, Timothy A.; Fu, Cary; Glaze, Daniel G.; Haas, Richard; Heydemann, Peter; Jones, Mary; Kaufmann, Walter E.; Lieberman, David; Marsh, Eric; Peters, Sarika; Ryther, Robin; Standridge, Shannon; Skinner, Steven A.; Percy, Alan K.; Neul, Jeffrey L. – American Journal on Intellectual and Developmental Disabilities, 2020
Rett syndrome (RTT) is a neurodevelopmental disorder that primarily affects females. Recent work indicates the potential for disease modifying therapies. However, there remains a need to develop outcome measures for use in clinical trials. Using data from a natural history study (n = 1,075), we examined the factor structure, internal consistency,…
