Pre-Course: Anatomy & Physiology in Balance & Vestibular System

This pre-course provides a comprehensive review and builds upon your knowledge of the vestibular system and its role in balance control. It's a required step for our Level 2 Senior Balance Retrainer course, ensuring you have the essential anatomical and physiological groundwork for advanced learning.

Who Should Enroll?

This course is designed for healthcare professionals who have completed our Level 1 Basic and Level 1 Balance Retrainer: Introduction to Vestibular Rehab courses and are ready to progress to more advanced balance assessment and treatment techniques.

Course Objectives:

By the end of this pre-course, you will be able to:

• Identify and describe the key anatomical components of the vestibular system, including the inner ear, vestibular nerve, brainstem nuclei, and cerebellum.

• Explain the physiological processes of maintaining balance, encompassing sensory input from the vestibular, visual, and somatosensory systems.

• Correlate vestibular anatomy and physiology with clinical presentations and balance assessment findings.

• Apply your understanding of the vestibular system to improve patient evaluation and treatment strategies.

Course Content:

This pre-course will delve into the following topics:

• Anatomy of the Vestibular System:

  • Detailed exploration of the bony and membranous labyrinths of the inner ear

  • Structure and function of the vestibular hair cells and how they detect head movement

  • Pathways of the vestibular nerve and its connections within the brainstem

  • Role of the cerebellum in coordinating balance and movement

• Physiology of Balance:

  • Hair Cell Physiology: In-depth examination of hair cell structure, mechanotransduction (converting movement into neural signals), and the role of stereocilia and kinocilium in detecting head motion.

  • Vestibular Nerve Physiology: Exploring the characteristics of vestibular nerve fibers, including their response to stimulation, firing rates, and adaptation properties.

  • Ewald's Laws: Understanding the three laws governing the relationship between semicircular canal stimulation and eye movements provides insights into the vestibulo-ocular reflex (VOR).

  • Alexander's Law: Explaining how spontaneous nystagmus (involuntary eye movements) changes in different gaze positions, aiding in the diagnosis of vestibular disorders.

  • Push-Pull Phenomenon: Illustrating how the vestibular system utilizes opposing signals from paired structures (e.g., left and right horizontal canals) to enhance sensitivity and accuracy in detecting head movement.

  • Tates's and Shoemaker's Rules: Delving into the principles that guide the interpretation of nystagmus and aid in identifying the affected side and canal in vestibular disorders.

  • Visual System and Balance: Examining the role of vision in providing spatial orientation cues, stabilizing gaze (VOR), and its interaction with the vestibular system.

  • Proprioceptive System and Balance: Understanding how proprioceptors in muscles and joints contribute to body awareness, postural control, and balance.

  • Sensory Integration: How the vestibular, visual, and proprioceptive systems collaborate to maintain equilibrium.

  • Vestibulo-ocular reflex (VOR): Stabilizing gaze during head movement.

  • Vestibulo-spinal reflex (VSR): Maintaining postural stability.

• Clinical Applications:

  • Connecting anatomical and physiological knowledge to patient assessment and treatment planning

Assessment:

You must pass an online examination covering the pre-course material to ensure your understanding and readiness for the Level 2 course.
