Practical 1 Flashcards
How to do Dix Hallpike
-rot 45 degrees toward affected ear
-flexion 30 degrees
-lie pt supine fast, 20-30 degrees ext
-stay in position for about a min and check for nystagmus
How to perform Epley
-rot 45 degrees to affected side
-lie pt back, at least 20 degrees cervical ext
-hold until nystagmus/symps subside + 30 sec
-rot head to opp side 45 degrees, repeat
-pt roll to side and rot head to 45 degrees and tuck chin to sh, repeat
-help pt sit up while keeping head down
-sit for 3-4 mins, watch eye movements
What is the difference between Dixhall Pike and Epley? What are their purposes?
Dixhall pike: assessment of the posterior canals. Up beating torsional nystagmus means posterior canal affected. Down beating means anterior canal affected.
Epley: treatment for vertical canal BPPV
Difference between cupulolisthisasis and canalithiasis
Cupulo: the otoconia (crystals) are stuck on the cupula. Symptoms start immediately and are persistent. There is no change in nystagmus intensity
Canal: the otoconia are stuck in the canal. Symptoms start within 1-40 seconds, but are short in duration (<1 min). The nystagmus fluctuates in intensity
What are the symptoms of PD?
inability to voluntarily control ADLs, akinesia, bradykinesia, rigidity, tremor, gait, speech
What are the cardinal signs of PD?
tremor, rigidity, akinesia, bradykinesia, postural instability
What is the difference between cogwheel and lead pipe ridigity?
Cogwheel: jerky resistance through range of motion
Lead pipe: consistent resistance through ROM
Difference between festination and FOG?
Festination: abrupt inability to control speed
FOG: sudden abrupt inability to initiate any movement
Difference between KP and KR?
KP: knowledge of performance, info about parameters/characteristics of movement
KR: knowledge of results, info about the outcome of movement (ex. performer’s score, time)
Concurrent feedback
feedback during movement (KP)
Ex. info about joint position during ex
Terminal feedback
given after whole movement, helps evaluate overall performance
Immediate feedback
given immediately after a part of the movement; still during activity, helps correct specific parts
Delayed feedback
given after a brief time delay that allows learner brief time for self-assessment
Summary feedback
given after a set number of trials
Faded feedback
given first after every trial, then less frequently over time.
Most feedback given in beginning, then decreases over time
