Quantifying wheelchair activity of children: a pilot study

Area of Science:

• Pediatric rehabilitation
• Assistive technology
• Biomechanics

Background:

• Understanding wheelchair mobility in children is crucial for developing effective interventions.
• Limited data exists on real-world wheelchair activity patterns in pediatric populations.

Purpose of the Study:

• To investigate mobility-related wheelchair activity in children within their community environment.
• To analyze differences in wheelchair usage between manual and electric-powered wheelchair users.
• To explore potential gender-based variations in wheelchair mobility.

Main Methods:

• Data logging devices were used to collect mobility data from 18 children (8-17 years) independently using wheelchairs.
• Activity data was recorded for 5 days, excluding the first and last day due to device attachment/removal timing.
• Wheelchair activity metrics included distance traveled, speed, and start/stop frequency.

Main Results:

• Children using manual wheelchairs traveled an average of 1602.31 m/day, while electric-powered wheelchair users traveled 1752.42 m/day.
• Significant gender differences were observed, with boys traveling further than girls (P = 0.008).
• Manual wheelchair users had a higher daily average of starts/stops per thousand meters compared to electric-powered wheelchair users.

Conclusions:

• Gender appears to be a factor influencing wheelchair activity variability in children.
• These findings provide a basis for future research into pediatric wheelchair mobility.
• Further investigation is needed to understand the implications of these mobility patterns.
