Study design
The study compared an omni-directional accessible wheelchair with a conventional wheelchair in a simulated care setting. Twenty healthy volunteers were randomly assigned equally between the two groups, with 10 participants using each wheelchair type. Researchers recorded caregivers’ positions during operation and the time required to complete the wheelchair operation task.
Wheelchair design
The omni-directional accessible wheelchair uses four swivel casters to support movement in multiple directions. It also has two vertical handles positioned at the front of the armrests, enabling caregivers to operate the chair from locations other than directly behind it. The study addressed the potential usefulness of multidirectional operation in real-world care settings.
Reported results
All participants assigned to the omni-directional wheelchair operated it from positions other than the rear. This pattern became more pronounced as trial numbers increased, and the group completed the operation task in less time than the conventional-wheelchair group. The record concludes that the design may be suitable and effective in real-world care settings, while noting that the described evidence involved healthy volunteers and a simulated task.
