| problem with vestibular trauma |
|
Definition
| hair cells and nerve do not regenerate |
|
|
Term
| Vestibular trauma: and VOR |
|
Definition
|
|
Term
| Vestibular trauma: sensory mismatch means what |
|
Definition
| mismatch between somatosensory and visual with abnormal vestibular input |
|
|
Term
| Vestibular trauma: what is tx based on? |
|
Definition
compensation
increasing the reponse of remaining vestibular system
CNS reorganization to optimize function |
|
|
Term
| Vestibular trauma: tx is based on compensation and requires what |
|
Definition
| exposure to stimuli that challenge the styem to approximate normal gaze stability and regprogram eye movevements and postural response |
|
|
Term
| Vestibular trauma: tx requires exposure to stimuli that challenge the system. what does this mean in terms of VAS |
|
Definition
| if 5/5 is a trip to the ER, work within a 1-3 range |
|
|
Term
| tx theories: 3 principles |
|
Definition
adaptation
habituation
substitution |
|
|
Term
| tx theories: what is the stimulus for adaptation |
|
Definition
| retinal slip (movement of image across the retina) |
|
|
Term
| tx theories: effect of adaptation ex |
|
Definition
| adaptation alone decreases symptoms of disequilibrium and improves balance while walking |
|
|
Term
| tx theories: what are the adaptation exercises? |
|
Definition
VOR x1 (normal VOR)
VOR x2 (VOR with head and thumb giong in opposite directions) |
|
|
Term
| tx theories: what should the pt's goal for adaptation be? |
|
Definition
| 30 seconds of VORx2 without symptoms increasing |
|
|
Term
| tx theories: explaning adaptation ex to the pt |
|
Definition
| symptoms can increase, but should not be excessive (4-5/5) and should not last more than 20 minutes after cessation of exercise |
|
|
Term
| tx theories: purpose of habituation |
|
Definition
| repetitive exposure to provokign movements to improve pt's tolerance ot those movements |
|
|
Term
| tx theories: best method to evalaute habituation |
|
Definition
| MSQ (motion sensitivity quotient) |
|
|
Term
| tx theories: how to perform habituation ex |
|
Definition
| want to moderately provoke your symptoms while not shutting down your system with excess symptoms. Excess symptoms will not let the CNS habituate and the pt may get anxious |
|
|
Term
| tx theories: Habituation exercise instruction |
|
Definition
| perform reps (up to 5) 2-3 x a day |
|
|
Term
| tx theories: what is substitution used for? |
|
Definition
| bilateral vestibular loss as in gentomyocin poisoning (ototoxicity) |
|
|
Term
| tx theories: goal of substitution |
|
Definition
| applying and masteirng alternative strategies to replace the lost or compromised function |
|
|
Term
| tx theories: substition ex (2) |
|
Definition
postural stability
gaze stability |
|
|
Term
| tx theories: substitution ex: postural stability: what is it? |
|
Definition
| balance ex with and without visual and somatosensory cues |
|
|
Term
| tx theories: substitution ex: gaze stability what is it? |
|
Definition
eye and head movements between 2 targets
remember target practice |
|
|
Term
| tx theories: ways to progress tx (5) |
|
Definition
time/reps
BOS/Hand support/visual focusing
Changing surfaces
Distance and range of targets/positions
