Maintaining balance in seated reaches
Authors: Matthew B. Parkinson, Don B. Chaffin, Matthew P. Reed
The aim of this study is to gain insight into how people maintain their balance while performing seated reaches. The requirement to maintain balance is a significant contributor to reach difficulty, and in some cases exceeds strength and range of motion as the primary limiting factor in achieving a specific reach. Maintaining balance is often more difficult for people who use wheelchairs (Figure 1), particularly for those with a spinal cord injury. A better understanding of balance-maintaining behavior will allow development and improvement of tools for the design of workspaces and other environments. This paper details a method for investigating the role of balance in seated reaches and presents preliminary results.
