Summary
Assistive technology interventions significantly improved environmental control, physical activity, and posture for individuals with severe intellectual and multiple disabilities. These programs enhanced happiness and independence, offering a valuable resource for this population.
Area of Science:
- Assistive Technology
- Disability Studies
- Rehabilitation Engineering
Background:
- Individuals with severe to profound intellectual disability and visual or motor impairments often face passivity, isolation, and reduced physical activity.
- Limited environmental stimulation and incorrect body postures are common challenges in this population.
- Previous interventions focused on increasing environmental stimulation through adaptive responding and assistive technology.
Purpose of the Study:
- To assess two intervention programs designed to enhance environmental control and physical activity for individuals with intellectual and multiple disabilities.
- To help participants with severe intellectual disability and blindness alternate between music and physical activity.
- To assist participants with severe to profound intellectual disability, visual/motor impairments, and postural issues in accessing stimulation, engaging in activity, and improving posture.
Main Methods:
- Two single-case research designs were employed to evaluate the intervention programs.
- Technology included smartphones with MacroDroid, pressure sensors for music activation, proximity sensors for physical activity monitoring, and mini speakers.
- Participants engaged in music periods and activity periods, with posture monitored in the second program.
Main Results:
- Participants demonstrated high independence (94.7%-99.7%) in activating music and performing physical activities.
- Mean session time in correct posture increased significantly (71.1%-89.6%) from baseline (18.8%-36.5%) in program 2.
- Eight of nine participants showed increased happiness levels during program sessions compared to control sessions.
Conclusions:
- The developed intervention programs show promise as effective tools for supporting individuals with severe to profound intellectual and multiple disabilities.
- These programs can enhance environmental control, physical activity, posture, and overall well-being.
- The findings suggest a valuable resource for improving the quality of life for this population.
