Handgrip Strength, Trunk Muscle Endurance, and Functional Mobility in Adolescents With Mild Intellectual Disability

This comparative, cross-sectional observational study examined handgrip strength, trunk muscle endurance, and functional mobility in adolescents aged 12-18 years with mild intellectual disability and compared their performance with typically developing peers. A total of 51 participants were evaluated during a single assessment session, including 24 adolescents with mild intellectual disability and 27 typically developing adolescents. Handgrip strength was measured using a digital hand dynamometer, trunk muscle endurance was assessed using the McGill trunk endurance test battery, and functional mobility was evaluated using the Timed Up and Go Test and the Timed Up and Down Stairs Test. The study also examined the relationships among handgrip strength, trunk muscle endurance, and functional mobility.
