NEURO Flashcards
Bradykinesia
Finger Tapping
Hand Movements
Pronation-Supination
Toe taps
Often very asymetrical - PC one limb. so test both sides
Rated by the MDS UPDRS
Dont memorise scoring.
Impact of Bradykinesia
Hypomimia (facial expression)(mask)
Hypophonia (soft voice)
Short steps, shuffling gait
Micrographia
Rigidity
Hypotonia and Hypertonia
Spasticity and Rigidty
Paratonia and Myotonia (less common)
Increased resistance to passive movement
Do not learn the rating tool.
Determine between spasticity and rigidty
Distribution
Clinical Context
Associated signs
Effect of Velocity- spasticity worse with speed, better when slower but rigidity is present regardless
Synkeinesis- move another part of body and rigidity gets worse.
Tremor
RESTING At completely relaxed state, slow tremor will come out.
Look at speed- physiological will be fast, pathological will be slow.
Upper limbs in parkinsons, pill rolling.
Re-emergent- same muscle joints and frequency but error at rest, reduces/ disappears at movement.
Essential/action
leaves at movement, occurs at sustained postures.
Scale based on amplitude- do not learn.
Cogwheel rigidity
Rigidity and tremor superimposed.
Jumps in movement of the wrist
feeling the tremor
Gait
Reduced velocity
Reduced cadence
Reduced stride length
Asymmetric stride length
Reduced arm swing
Freezing in Gait
Motor blocks during walking:
gait initiation, turning, passing through a doorway, threshold, line on floor- zebra crossing
Postural instability
Pull test and theyll fall back- normal response is to shuffle to regain balance.
Camprocormia- bending forward
Pisa syndrom- titling
Striatal hand/foot- flexion at PIP , relax at DIP
RBD
Rem Sleep Behaviour Disorder
Act out your dreams
Kicking, flailing
Early feature
Cranial Nerve exam
INTRODUCTION
Introduce yourself
Explain examination.
Obtain consent
Offer chaperone + explain supervisor will re-examine (for ophthalmoscopy)
Clean hands
Position your patient sitting and sit opposite them
Cranial Nerve
GENERAL INSPECTION
Facial asymmetry
Eye related signs
Medical aids – glasses, eye patch, hearing aids, pen and paper for communication
Hearing aids
Fasciculations
Scars
back of ear – acoustic neuroma
craniotomy
in front of ear – parotid gland tumour, may have associated ipsilateral facial nerve palsy
Tracheostomy, nasogastric or PEG tubes
Cranial Nerve Exam
OLFACTORY NERVE (CN I- SENSORY)
“Do you have difficulty with your sense of taste or smell?”
Cranial Nerve Exam
OPTIC NERVE (CN II- SENSORY)
VISUAL ACUITY: Snellen chart (with and without glasses)/ counting fingers, hand movements, light/ dark
COLOUR VISION: Ishihara plates
VISUAL INATTENTION
VISUAL FIELDS
CENTRAL VISION
BLIND SPOT
Cranial Nerve Exam
OCULOMOTOR (CN III- MOTOR), TROCHLEAR (CN IV- MOTOR) and ABDUCENS (CN IV SENSORY+MOTOR)
EYE MOVEMENTS; including commenting on squints, nystagmus
PUPILS
Inspection
Test reaction to LIGHT (Direct and consensual)
