Tremors Flashcards
def resting tremor
occurs when body part is relaxed and supported vs gravity
def action tremor
occurs with voluntary contraction of muscle
def postural tremor
subtype of action tremor
occurs when body part is voluntary maintained vs gravity
def isometric tremor
subtype of action tremor
occurs when a body part is contracted vs a rigid stationary object
def kinetic tremor
subtype of action tremor
occurs with any form of voluntary movement
def intention tremor
subtype of kinetic tremor which is a subtype of an action tremor
kinetic tremor amplified as the target is reached
key features of essential tremor
MC pathologic tremor
- action tremor
key features of enhanced physiological tremor
- normal tremor
- abrupt onset + spon remission
- extinction with distraction
- might be triggered - caffeine, anxiety, sleep deprivation
key features of parkinsonian tremor
- resting pill rolling tremor
- unilateral
- fades with voluntary movement
key features of psychogenic tremor
- abrupt tremor
- spon remission
- changing characteristics
- extinction with distraction
- often preceded by a stressful event
key features of cerebellar tremor
disabling low-freq slow intention or postural temporal
DANISH s/s
key features of drug or metabolic-induced tremor
exacerbation of any type of tremor
