Chapter 8 discusses the proprioceptive system, including key terminology such as grading of force, proxy touch, and kinesthetic feedback. It then reflects on common classroom activities impacted by the proprioceptive system such as sitting upright, writing, playing at recess, and participating in PE class. Finally, this chapter delineates signs of proprioceptive understimulation, and poor proprioceptive discrimination and provides concrete, practical strategies for each respective sensory need that can be used in the school environment. Included in this chapter are diagrams, interactive scenarios, and an activity to simulate proprioceptive understimulation.
