Is there any comparative study in the literature regarding the vestibular rehabilitation effectiveness of patients with previous right or left vestibular hypofunction?
Yuşa Başoğlu Although central vestibular dysfunction may appear peripheral, peripheral vestibular dysfunction will never appear central. Proprioceptive impairments ipsilateral to the lesion are the most consistent clinical indicator of central vestibular dysfunction.
What you mean by localisation of peripheral vestibular lesion!!!
Rt vs left ear
Semicircular canals vs otolith
Hello Yuşa Başoğlu can you elaborate a bit on the question? I find it very interesting for analysis but it lacks a bit of development to be able to comment.
best,

Hello Ignacio Novoa Cornejo,
Thank you for your interest Ignacio Novoa Cornejo . Actually, the question I want to ask is, how does the vestibular compensation process work in right and/or left peripheral vestibular involvement? For example, can the development of a patient with canal paresis in the right or left ear as a result of the caloric test differ in vestibular rehabilitation?
Hello, Yuşa Başoğlu I think I understand:
1. First, we should consider a margin of normal asymmetry between each subject. So we will not know the vestibular function they had prior to being vestibular rehabilitation patients.
2. The right or left dominance that each person may have could influence the patient's ability to move, both to the left and to the right.
3. The ranges of cervical mobility that a patient has prior to the vestibular injury can influence the ranges in which it is necessary to work to adapt and/or habituate the vestibulo-oculomotor reflex.
4. I would recommend using parameters from the video head imposed test (vHIT) over the parameters from the caloric test—the vHIT determined degrees of movement that are useful in the rehabilitation process.
5. I would like to continue with this discussion since it is an exciting topic that I have asked myself many times. Will a left or right injury be more serious? Which one is easier or harder to recover? how to assume the capacity that the patient had? - Compared with the healthy ear? ...there are endless questions.
Best,
Ignacio
interesting discussion. I had not looked at vest rehab in this way. Now i may re review our patient data and see , if there is any such trends... atleast in new cases i can keep this in mind and see if there is any such issues.
Its also interesting to know that Ignacio Novoa Cornejo uses vHIT data , for rehab.
Do u use gain values to know is compensation has happned or not?...
The question that you asked Dr. Thontadarya about vestibular compensation measure using vHIT.
I think saccadic latency could be a useful measure to assess vestibular compensation. For eg. an overt saccade will show indicate vestibular hypo function but over the course of time, if the latency of saccades becomes less that is if the overt saccade changes to convert saccade this may indicate some kind of vestibular compensation.
