| UUMN:Neurological signs/neuromuscular characteristics | Test for Central Facial Weakness: Facial Droop but CAN wrinkle forehead,raise eyebrow,blink eye |
| UUMN:Speaker/Pt complaints | thick tongue |
| Hypokinetic: Place of lesion | Basal Ganglia: Substantia Nigra |
| Hypokinetic:Medical/Neurological conditions | Parkinsons |
| Hypokinetic:Speech/Auditory perceptual characteroistics | Hypophonia(pt may be unaware of) Breathy(VF bowing-but sometimes compensate by being harsh or high pitch Monopitch Reduced stress Inappropriate silences/delayed initiation (latency) Rate disturbances:increased rate,repeated phonemes,short rushes of s |
| Hypokinetic: Nonspeech Movement Deficits | Very reduced ROM- non speech repetitive Reduced ROM -individual movements |
| Hypokinetic:Neurologic signs/ Neurmuscular characteristic | Hypertonia-Rigidity (cogwheel-jerks) Hypomimia Resting tremor Micrographia Shuffling Gait Loss of Arm swing when walking Bradykinesia Hypokinesia Akinesia Postural Instability TRAP: Tremor[resting],Rigidity,Akinesia,Postural Instability |
| Hypokinetic:Speaker/Pt Complaints | Reduced Loudness (listener complaint) Rapid rate Mumbling or Stuttering Difficulty initiating speech Reports that "people tell them..."- not their perception Stiff lip- also other stiffness and cramps |
| HYPERkinetic: Place of lesion | Basal Ganglia: Striatum |
| Hyperkinetic:Medical/neurological conditions | Dystonia, Huntington's CHorea |
| Hyperkinetic: CHOREA :Speech/Audiological perceptual characteristics | prolonged intervals variable rate inappropriate silences excess loudness variations prolonged phonemes Sudden forced inspiration/expiration (audible inspiration) Voice Stoppages (phonatory breaks)(phonatory instability) |
| Hyperkinetic: DYSTONIA :Speech/Audiological perceptual characteristics | Distorted Vowels Harsh Irregular artic breakdowns Inappropriate silences voice stoppages (phonatory:breaks,instability) Improves w/ sensory trick. Ex. Bite block |
| Hyperkinetic: Non speech Movement deficits | not important clues for dx |
| Hyperkinetic: Neurological signs/Neuro muscular characteristics | Adventitious Movements: Chorea Dystonia Dyskinesia Tics Myoclonus |
| Hyperkinetic: CHOREA :Speaker/Pt complaint | Effortful speech Involuntary oral movements chewing/swallowing difficulty |
| Hyperkinetic: DYSTONIA :Speaker/Pt complaint | Speech may be reported as normal Neck movements and pain Occasional Dysphagia Awareness of sensory tricks that reduce spasm temporarily |
| Ataxic: Place of Lesion | Cerebellum |
| Ataxic: medical/neurological condition | Damage to Cerebellum, TBI ? Unilateral Cortical stroke |
| Ataxic:Speech/ Auditory Perceptual Characteristics | Irregular articulatory breakdowns Scanning Speech: prolonged phonemes& excess/equal stress in ea syllable Excessive loudness variation hyponasality Vowel distortions Voiced for Voiceless errors |
| Ataxic:Non speech Movement Deficits | Irregular AMRs-Uncoordinated (SMR) ROM for individual and repetitive movements can be excessive |
| Ataxic:Common Neurological Signs/ Neuromuscular characteristics | Hypotonia Broad based gait- wide for balance Dysmetria Intention tremor Nystagmus |
| Ataxic:Speaker/Pt Complaint | "Drunk" speech Stumbling over words Biting Tongue or cheek when speaking/eating Deterioration of Speech w/ alcohol Poor coordination of breathing w/ speech |
| Flaccid: Place of lesion | PNS (CNs) |
| Flaccid: Medical/Neurological Conditions | Brain stem Stroke Unilateral Cortical Stroke |
| Flaccid:Speech/Aud Percept | Depends on CN or Nerves involved and if its bilater or unilateral lesion |
| Flaccid: Stress Testing Speech. WHy? | Useful ti ID Myasthenia Gravis |
| What is Myasthenia Gravis | rapid fatigue of muscular contractions over a short period of time. Depletion of acetylcholine |
| Stress Test:Task and performance? | Rapid Counting 1-50 MG- if pt deteriorates after 10, then resumes normal function once rested |
| Flaccid:Non Speech Movement Deficits | Reduced: muscle TONE, RATE of individual movements, RANGE of repetitive movements |
| Flaccid:Neurological signs/Neurmuscular characteristics | Atrophy Fasciculations Hypotonia Decreased gag- if high vagal lesion |
| Flaccid:Speaker/Pt complaint | Variation depending on the specific CN involved. Specific compensation depending on site of weakness Perceptual Features: HYpernasaility, Audible inhalation/exhalation, imprecise vowel/consonant production |
| Mixed: Medical/Neurological conditions | ALS: Spastic-Flaccid MS: Ataxic- Spastic TBI: Spastic-Ataxic or Flaccid-Spastic Stroke: Unilateral cortical |
| Differentiation between resting tremor associated with PD and Benign Essential Tremor | Resting tremor is degenerative. BET does not progress, but tends to improve w/alcohol. |
| CN V- Trigeminal: Function | Jaw elevation General face sensation General tongue sensation (ant 2/3) |
| CN V- Trigeminal: Tasks | Jaw elevation against resistance 6 Light and deep touch to pt face, eyes closed Right/Left light touch to tongue, eyes closed |
| CN VII- Facial: Function | Upper and Lower Face Taste to ant 2/3 tongue |
| CN VII- Facial: Tasks | Facial Movement:Wrinkle forehead,blink,smile,pucker Salt water/ Sugar water: what do you taste |
| CN IX- Glosspahryngeal: Function | General sensation to post 1/3 tongue Taste to Post 1/3 tongue |
| CN IX- Glosspahryngeal:Tasks | Test light touch Test taste of something sour |
| CN X- Vagus : Function | Pharynx- velum Larynx- Vfs no speech sensory |
| CN X- Vagus : Tasks | Velar elevation: ee-ee-ee Phonation:say "ah" for as long as you can Pitch glide: say ah, increase pitch |
| CN XII - Hypoglossal : Function | tongue no sensory |
| CN XII - Hypoglossal : Tasks | tongue at rest lateralization elevation/depression |
| Primitive Reflexives: | those which are present during infancy but tend to disappear during nervous system maturation. as brain degenerates/normal again primitive reflexes return. "release phenomena" |
| Snout Reflex | Test:light tap of finger on philtrum or tip of nose Abnormal:puckering,protrusion/elevation of lower lip, depression of mouth angles |
| sucking reflex | Test:stroke upper lip, from lateral to medial Abnormal: pursing of lips |
| Jaw refelx | Test:pt relaxed lips parted, jaw open. Tap chin Abnormal: quickly close jaw |
| Test for Central Facial Weakness | Observe Facial Droop- ask to wrinkle,blink Upper face DOES function: UMN lesion, contralteral, area 4 (facial region) Upper face DOESNT function: CN VII lesion, same side as droop |
| why? | Because Upper face (eyebrows,eyelids,forehead) are 50:50/bilaterally innervated |
| AMRs | Articulatory agility "pa pa pa "ta" "ka" rapid and precise |
| SMRs | Sequencing /coordination "Pataka" fast suggests ataxia or apraxia |
| Additional observations to make during tasks | rhythm ability to plose articulatory precision regularity/steadiness loudness pitch |
| High Vagal Lesion | Branches 1-3 palatal muscles & Larynx Hypernasality Soft Breathy voice Cant raise pitch |
| Low vagal lesion (4) | Spare palate inability to raise pitch soft breathy voice |
| Low vagal lesion (5) | Spare palatal muscles can raise pitch Breathy Voice |
