Course Overview

Selecting the correct resistance is essential for helping Dynamic Head Support Hardware respond appropriately to a wheelchair user's movement. In this Quick Class, Michelle Lange explains how resistance works, how elastomers absorb and return force, and how resistance affects movement and stability. The course reviews signs that resistance may be too soft or too firm and explains why head support positioning should be evaluated before changing resistance. Viewers will also learn how leverage, hardware configuration, and elastomer maintenance can affect overall performance.

Course Objectives

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

• Explain the role of resistance in Dynamic Head Support Hardware.
• Describe how elastomers absorb force, store energy, and assist the head support in returning to a starting position.
• Identify signs that resistance may be too soft or too firm for the wheelchair user.
• Understand how improper head support positioning can affect head and neck alignment.
• Explain how hardware link length and leverage can influence resistance requirements.
• Recognize when a firmer elastomer may be appropriate for a longer lever arm.
• Describe the difference between impact and rebound elastomers.
• Understand why elastomers should be inspected regularly for wear.|
• Explain why resistance should be evaluated during installation and fitting for each individual user.
