Vestibular Physiology for BSc Audiology Students
2021 Course. November 3rd, 10th, and 17th.
This year sees a return to face-to-face teaching for three sessions. We will be studying the balance system, diseases of balance, history taking, and examination over the three weeks.
Prior to this session you should have read topics 1 and 2 below. These will introduce the fundamentals. In class you will have an assessment via Kahoot! and we will have a chance to discuss areas of difficulty while we do that.
Following the Kahoot! we will discuss vestibular history taking, emphasising the need to focus on 'timings, triggers, and associations'.
Following the session you will be divided into 5 groups. Each group will prepare a short summary of a balance disorder for the following teaching session on 10th November.
The diseases to be presented are shown here together with some resources to use to make your presentation:
Benign Paroxysmal Positional Vertigo (BPPV)
AAO-HNS Guidelines for the management of BPPV. (There is a lot of really useful information in there. Focus on the posterior canal BPPV information)
Wikipedia page. Really good wiki coverage.
Vestibular Neuritis and labyrinthitis
Persistent postural-perceptive dizziness (PPPD)
Stroke affecting the anterior inferior cerebellar artery
We will review the concept of vestibular failure and compensation, how is happens, and what we can do to enhance it. This will be via a Kahoot! and discussion.
Student pairs will present their work on balance diseases. 10 minutes maximum. Each presentation must include a summary of the typical findings from history taking. 'Timings, triggers, and associations'. They must also include diagnostic tests / exams, and management.
Do the vestibular cases test. Click on the link to be taken to a short test on case histories.
Read up on nystagmus, Alexander's law, the vestibulo-ocular reflex and Dix-Hallpike and Epley manoeuvres.
This is a practical session during which we will learn examination skills commonly used in the assessment of a dizzy patient. These will include such things as the assessment of nystagmus and Alexander's law, the VOR, Dix-Hallpike testing, and the Epley manoeuvre.
