Accelerometry-Based 24-Hour Movement Behavior in Manual Wheelchair Users: A Cross-Sectional Study

Area of Science:

• Physical therapy and rehabilitation science.
• Movement science and biomechanics.
• Disability studies and assistive technology.

Background:

• Understanding 24-hour movement behaviors is crucial for manual wheelchair users' health.
• Current movement guidelines may not adequately address the unique challenges faced by this population.
• Accelerometry offers an objective measure of daily movement patterns.

Purpose of the Study:

• To characterize 24-hour movement behaviors in manual wheelchair users.
• To investigate differences in movement behaviors based on sex, disability severity, and onset.
• To assess adherence to established physical activity, sleep, and sedentary behavior guidelines.

Main Methods:

• A cross-sectional study involving 72 adult manual wheelchair users.
• Free-living assessment of movement behaviors over seven days using accelerometry.
• Sociodemographic questionnaire to gather data on disability characteristics.

Main Results:

• No participants met all three 24-hour movement guidelines, primarily due to unmet sedentary behavior criteria.
• 90% met the physical activity guideline, and 69% met the sleep guideline.
• Individuals with acquired disabilities showed higher physical activity and lower sedentary time than those with congenital disabilities.

Conclusions:

• Sedentary behavior represents the most significant barrier to meeting 24-hour movement guidelines for manual wheelchair users.
• Findings suggest a need for tailored, disability-specific movement guidelines.
• Guidelines should consider the distinct daily realities and circumstances of manual wheelchair users.
