The physical and psychological impact of using a computer-based environmental control system: a case study

Area of Science:

• Assistive Technology Research
• Rehabilitation Engineering
• Disability Studies

Background:

• Evaluating the impact of computer-based environmental control systems (ECS) is crucial for individuals with severe physical disabilities.
• The Subvenio system was assessed for its physical and psychological effects on a 46-year-old woman with tetraplegia.
• Understanding user expectations and factors contributing to successful technology adoption is key.

Observation:

• Quantitative measures showed no significant changes in global functioning or emotional wellbeing.
• Specific daily activities, such as controlling lights and television, saw increased user engagement.
• Qualitative data revealed enhanced independence and reduced reliance on caregivers.

Findings:

• The Subvenio system provided notable qualitative benefits, including increased autonomy.
• Factors such as device characteristics and personal elements (e.g., pain) influenced system usability and benefit.
• While global functioning remained unchanged, task-specific improvements and independence were observed.

Implications:

• Assistive technology (AT) development should prioritize factors influencing successful use, including user expectations and personal characteristics.
• Open communication between healthcare providers, service providers, and AT users is essential to manage expectations and ensure ongoing needs are met.
• Integrating quantitative and qualitative research methods is recommended to fully understand the complex relationship between AT/ECS and user outcomes.
