Summary
Dual task (DT) training improved cognitive performance in individuals with intellectual disability (ID). Single task (ST) training did not enhance postural control under DT conditions.
Area of Science:
- Neuroscience
- Developmental Psychology
- Rehabilitation Science
Background:
- Individuals with intellectual disability (ID) often exhibit challenges in dual-tasking, affecting both postural stability and cognitive function.
- Understanding the impact of different training paradigms on these abilities is crucial for improving daily functioning in this population.
Purpose of the Study:
- To investigate the effects of 8-week dual task (DT) training versus single task (ST) training on postural and cognitive performance in individuals with intellectual disability (ID).
Main Methods:
- Three groups were studied: ST training group (STTG), DT training group (DTTG), and a control group (CG).
- Postural sway and cognitive performance were assessed separately and simultaneously before and after the 8-week intervention period.
Main Results:
- Initially, both postural sway and cognitive performance were worse in dual-task (DT) conditions compared to single-task (ST) conditions across all groups.
- Following training, postural sway remained elevated in DT conditions for the STTG and CG, but not the DTTG.
- Cognitive performance significantly improved after training exclusively in the DTTG.
Conclusions:
- Dual task training is effective in enhancing cognitive performance in individuals with intellectual disability.
- Single task training does not improve, and may even impair, postural control in dual-task situations for individuals with intellectual disability.
