Perceptions of anterior tilt seat function among power wheelchair users: A qualitative study

Abstract

The anterior tilt power seat function is designed to provide users with functional access and reach that is otherwise unachievable using other power seat functions. While the benefits of posterior tilt-in-space, power recline and seat elevation have been documented, the influence of the anterior tilt seat function has yet to be sufficiently explored. Moreover, no studies to date have looked at the perceptions of users in a home environment. The purpose of this qualitative study was to gain a better understanding of the perceptions of power wheelchair users on the anterior tilt seat function and its uses in daily activities both inside and outside users’ homes. Ten power wheelchair users (mean age: 26.8±12.33) with seat elevation, but not anterior tilt function, on their current wheelchair participated in 3 study visits that were conducted within their home. Users evaluated the anterior tilt function on Permobil M3 or F3 chairs for a variety of activities. User perspectives were obtained through semi-structured interviews on parameters such as comfort, usability, and effectiveness at enhancing functionality. Results indicate several potential benefits of the anterior tilt seat function as well as areas in which improvements are possible. Users found anterior tilt to be beneficial in a variety of community settings, but also found the safety equipment restrictive. The findings of this study provide insight into activities participants found anterior tilt beneficial as well as suggestions for potential design changes for future iterations.
