Study approach
Researchers collected three-dimensional postural data from 75 people seated in their personal wheelchairs. They used HumanShape software to create individualised baseline avatars in automotive posture, then manually adjusted those avatars to match field-scan postures. The analysis compared anatomical landmarks and body-segment orientations with wheelchair and participant characteristics.
Differences from automotive posture
The study found differences in pelvis, abdomen and knee angles relative to standard automotive posture. Its findings indicate that a reclined posture was common among wheelchair users, while a more forward neck angle offset that tendency. The research record describes these results as posture observations, rather than treatment or clinical recommendations.
Relevance to vehicle protection
The researchers also reported significant posture differences associated with gender, body-mass index and disability. They said the findings have implications for designing occupant protection systems, an area where the source notes that wheelchair-user posture has received limited automotive-safety research. Automated driving systems may provide benefits for people travelling while seated in wheelchairs, according to the study context.
