Course Overview

Choosing the correct resistance is essential for the Dynamic Rocker Back Interface to function properly. In this Quick Class, Michelle Lange explains how elastomers provide resistance, absorb forces, store energy, and help return the back to an upright position. Viewers will learn how to recognize when resistance is too soft or too firm and how factors such as wheelchair tilt, backpacks, and movement-seeking behavior can affect resistance selection. The course also reviews available elastomer resistance levels and the importance of checking components regularly for wear.

Course Objectives

After completing this Quick Class, viewers will be able to:

• Explain the role of resistance in a dynamic wheelchair back.
• Describe how impact and rebound elastomers function within the Dynamic Rocker Back Interface.
• Identify the available levels of elastomer resistance.
• Recognize signs that resistance may be too firm for a wheelchair user.
• Recognize signs that resistance may be too soft.
• Understand how wheelchair tilt and added weight can influence resistance assessment.
• Explain why individuals who seek movement may benefit from a softer resistance level.
• Understand how improper resistance can reduce force absorption and potentially transfer forces to the wheelchair frame.
• Recognize when an elastomer should be changed or replaced.
• Understand the importance of evaluating resistance during delivery, fitting, and ongoing follow-up.
