简要总结
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.
详细描述
Study Design
This was a comparative, cross-sectional observational study. Participants were not assigned to any treatment, exercise program, or other intervention. All assessments were completed during a single study visit, and no 8-week intervention or follow-up assessment was conducted.
Participants
The study included 51 adolescents aged 12-18 years. The mild intellectual disability group consisted of 24 adolescents with a clinical diagnosis of mild intellectual disability according to DSM-5 criteria. The comparison group consisted of 27 typically developing adolescents without a diagnosis of intellectual disability, neurodevelopmental disorder, neurological disease, orthopedic condition, or serious systemic disease affecting assessment performance.

研究组 & 干预措施
Mild Intellectual Disability Group
Adolescents aged 12-18 years with a clinical diagnosis of mild intellectual disability according to DSM-5 criteria, who were able to understand and follow simple verbal instructions and had no orthopedic or neurological limitation preventing completion of the assessments.
Typically Developing Group
Typically developing adolescents aged 12-18 years without a diagnosis of intellectual disability, neurodevelopmental disorder, neurological disease, orthopedic condition, or serious systemic disease that could affect completion of the assessments.
结局指标
主要结局
Mean Hand Grip Strength in kilograms (kg)
时间窗: At the single study assessment visit (Day 0)
Handgrip strength was measured separately for the right and left hands using a digital hand dynamometer. Three trials were performed for each hand in a standardized seated position, and the mean of the three trials was recorded in kilograms. Higher values indicated greater handgrip strength.
Trunk Muscle Endurance Assessed With the McGill Test Battery
时间窗: At the single study assessment visit (Day 0)
Trunk muscle endurance was assessed in seconds using the McGill trunk endurance test battery, consisting of the trunk flexor endurance test, trunk extensor endurance test, right side bridge test, and left side bridge test. The duration for which each standardized test position was maintained was recorded in seconds. Longer durations indicated greater trunk muscle endurance.
Functional Mobility Assessed With the Timed Up and Go Test
时间窗: At the single study assessment visit (Day 0)
Functional mobility was assessed using the Timed Up and Go Test. The time required to complete the standardized test was recorded in seconds. Shorter completion times indicated better functional mobility.
次要结局
- Functional Stair Mobility Assessed With the Timed Up and Down Stairs Test (TUDS)(At the single study assessment visit (Day 0))
