Examination Flashcards
what to include in a history??
medical history: include location of lesion
social history: employment?
living environment: where do they live? type of dwelling. stairs? railings? anyone live with them? are they able to assist in their care? do they work? do they have a support system? who are they (family and services)? working?
Prior level of function (PLOF): did they use an AD? are they a community ambulatory? driving?
Medications: prescription and OTC
Chief complaint: *** where to start! motivation for patient
patient goals
what are their goals for therapy?
if appropriate, what are the family’s goals for therapy?
can also ask caregiver
what are the 5 review of systems?
cardiovascular/pulmonary
integumentary
musculoskeletal
neuromuscular
communication/affect, cognition, and language system (motor learning, retention of skills)
tests and measures:
aerobic capacity/endurance anthropometric characteristics (ht, wt, gender) arousal, attention, cognition assistive/adaptive devices circulation cranial &peripheral nerve integrity environmental, home and work barriers gait locomotion and balance integumentary integrity joint integrity and mobility motor function (motor control & learning) muscle performance neuromotor development and sensory integration orthotic, protective, &supportive devices pain posture ROM/ muscle length reflex integrity self care & home management (ADL, IADL) sensory integrity ventilation & respiration/gas exchange work, community & leisure integration
what is tone?
=tension of a muscle which can be altered either consciously or automatically, centrally or peripherally
examine tone first bc changes in position and movement will change or influence tone
what are the 4 types/categories of tone?
1- flaccidity= absence of tone (“deadweight”, physically have to hold the limb up- no ms. activation)
2- hypotonia= decreased tone (LMNL)
3- normal
4- hypertonia = increased tone (UMNL)
- spasticity
- rigidity
what is hypotonia? how is it produced?
flaccidity/hypotonia can be produced by injury to a number of CNS loci involved in the cerebellar cortical connections. These include the dentate nucleus of the cerebellum, the ventrolateral nucleus of the thalamus and the premotor cortex.
hypotonia is also seen with lesions of the medullary pyramids
LMNL (a few with UMNL (>90% of UMNL are hypertonia)
what is hypertonia? how do you test for it?
hypertonia= increased tone
need to test whether it is spastic or rigid
test tonic stretch reflex and the phasic stretch reflex
what is the tonic stretch reflex?
tonic stretch reflex of hypertonicity= resistance to passive movement
increase in tone with speed (feel a catch-increase in resistance) but no difference when moving slow= SPASTICITY- velocity dependent
not velocity dependent- constant= RIGIDITY
what is the phasic stretch reflex?
AKA monosynaptic reflex, myotonic reflex, DTR
SPASTICITY= increased DTR
what is spasticity?
how is it graded?
=increase in tonic stretch reflexes (velocity dependent) and increase in phase stretch reflex (DTR)
graded by the Modified Ashworth Scale (measures tonic stretch reflex)
what are the grades for the Modified Ashworth Scale?
0 = no increase in muscle tone (absent)
1= slight increase in muscle tone (catch and release or min resistance at end range) (minimal)
1+ = slight increase in muscle tone through less than 1/2 range
2 = more marked increase muscle tone through must ROM, but affected part moves easily (moderate)
3= considerable increase in muscle tone, passive movement difficult (maximal)
4= affected part(s) rigid in flexion or extension
**tone is constantly changing (weather, mood) so it is important not to get caught up in scoring
what are the types of spasticity?
clasp knife phenomenon
decerebrate posturing
decorticate posturing
what is clasp knife phenomenon?
spasticity in which there is an initial resistance during passive stretch followed by a sudden melting of that resistance
tends to be extensors
what is decerebrate posturing?
hyperactive state associated with extension of upper and lower extremities
(worst)
velocity dependent-spastic
what is decorticate posturing?
hypertonic state associated with flexed upper extremities and extension in lower extremities
(better- red nucleus is functioning)
what is rigidity?
hypertonia characterized by increased responsiveness of tonic stretch reflexes which is velocity independent and which occurs in the absence of heightened phasic stretch reflex
most rigidity is mobile but patients complain of “stiff and tight”
what are 3 types of rigidity?
cogwheel
lead pipe
Genghalten
what is cogwheel rigidity?
represents a catch and release of the muscle tension throughout the range of passive movement
what is lead pipe rigidity?
associated with a stiff “plastic” or “lead pipe” type of increased resistance to passive movement, which is independent of extent or rapidity of movement
what is Genghalten rigidity?
heightened resistance to passive movement is elicited by contact or holding. usually assume normal postures at rest and muscles are visibly slack. Tension is not increased by active movement but by handling.
frontal lobe lesion- these patients are very functional, don’t feel stiff/tight- but the moment you touch them they stiffen up
what are 3 things to test for sensory integrity?
recognition
interpretation
attention
types of sensory testing:
sharp/dull discrimination
vibration
temperature
light touch
proprioception
kinesthesia
stereognosis: tactile recognition of objects
graphesthenia: ability to recognize writing on skin
double simultaneous stimulation
peripheral impairments
spinal cord impairments
brain impairments: sensory neglect& hypersensitivity
motor function/muscle performance:
MMT is indicated ONLY when the spasticity is NOT present– pt. can’t isolate movement = invalid test
the motor inspection begins as soon as you meet the patient:
- study every activity: how the pt. sits, walks, gestures; posture; general level of activity
- unobtrusive observation of the pt’s spontaneous activity often discloses more than formal tests, particularly for infants and mentally ill patients
