Abstract
This study analyzed wheelchair caster failures and service repairs from a network of wheelchair suppliers to determine the frequency of failures across manufacturers and models and investigate relationships between them. Results from 6470 failures and 151 service repairs showed significant associations between failure types and manufacturers/models. Users of tilt-in-space and higher-group power wheelchairs experienced a higher proportion of high-risk failures. Service repairs negatively correlated with high-risk manual wheelchair caster failures. The findings highlight the need for improved product quality and preventative maintenance to reduce failures and user consequences.
