Can global positioning systems quantify participation in cerebral palsy?

Area of Science:

• Rehabilitation science
• Assistive technology
• Pediatric physical therapy

Background:

• Assessing motor-related participation in individuals with cerebral palsy (CP) is crucial for understanding functional limitations.
• Traditional participation measures may not fully capture objective, real-world activity levels.
• Cerebral palsy affects motor skills, potentially limiting participation in daily activities.

Purpose of the Study:

• To evaluate the utility of global positioning systems (GPS) for assessing motor-related participation in adolescents with cerebral palsy.
• To compare GPS-measured outdoor activity and travel patterns between an adolescent with CP and a healthy sibling.
• To correlate GPS findings with self-reported participation data.

Main Methods:

• Two adolescent sisters, one with diplegic cerebral palsy and one healthy, were monitored using GPS devices.
• Outcome measures included traveling distances, time spent outdoors, and the Children's Assessment of Participation and Enjoyment questionnaire.
• Comparative analysis was performed between the two participants.

Main Results:

• GPS data revealed the adolescent with cerebral palsy spent less time outdoors and traveled shorter distances than her sibling (P = .02).
• The participant with CP engaged in activities primarily at home and alone, consistent with questionnaire findings.
• Objective GPS measurements indicated significantly lower outdoor activity in the adolescent with CP, ranging from 29% to 53% of her sibling's levels.

Conclusions:

• Global positioning systems can objectively quantify reduced outdoor activity and participation in adolescents with cerebral palsy.
• GPS technology offers a valuable tool for complementing traditional assessments of participation in individuals with CP.
• This technology has the potential to provide objective data on real-world participation for individuals with motor impairments.
