Exam 1 Flashcards
What does HOAC stand for
- hypothesis-oriented algorithm for clinicians
What is HOAC
- method for hypothesis development
- provides a good algorithm to use for reflection of clinical practice
Forward Reasoning
- have a pre-existing expectation and looking for information that fits
- uses past experiences
- “if, then” pattern recognition
- i.e. if X is a frog then it croaks and eats flies
Backward Reasoning
- starts with a hypothesis and works backwards
- if X croaks and eats flies, then X is a frog
Interactive Reasoning
- teaching, patient focused
- getting to know the patient and involving them in the problem solving process
- can be difficult for a novice
Conditional Reasoning
- reflection time
- good or bad
- exhausting
- difficult for a novice
- hallmark of an expert clinician
Two Models of Health and Disability
- Nagi model
- international classification of function model
Nagi model
- pathology
- impairment
- functional limitation
- disability
International classification of Function (ICF) Model
- ability slant to the nagi model
- body structure and function
- activity
- participation
- contextual factors
Coding
- certain codes are used and mean different things
- i.e. ICD-9, 742.2 is lumbago
- you can code to reflect the ICF
Palpation objectives
“can only be learned by palpation”
- detect abnormal tissue texture and location
- detect asymmetries of position
- detect sensitivity to palpation/pressure
- detect changes in findings to note improvements/regressions of symptoms
- fingertips have most sensory
3 phases of palpatory sense
- reception: proprioceptors and mechanoreceptors of the hand receive stimulation from the tissues palpated
- transmission: information transmitted through peripheral and central nervous system to brain
- interpretation: this information is analyzed and interpreted
Roles of different parts of hand in palpation
- thumb and fingertips: pressure probes for differences in depth
- finger pads: fine discrimination of textural differences, skin contour temperature
- palm of hand: stereognostic sense of contour and shape
Stereognosis
- the ability to perceive and recognize the form of an object using cues from texture, size, spatial properties
- testing this involves patients identify common objects placed in hands without visual clues
Principles of palpation
- move SLOW
- avoid excessive pressure
- layer your palpation, don’t start deep (less is more)
- concentrate/focus
Active ROM
- the arc of motion attained by a subject during unassisted voluntary joint motion
- allows examiner to screen for abnormal movements
- assess patient’s willingness to move
- assess patients ROM and coordination
- gives an indication of contractile tissue status
Passive ROM
- the arc of motion attained by an examiner without assistance from the subject
- enables the examiner to detect pain, give an indication of true joint mobility, and assess the tissue that is limiting the motion (end feel)
- provides info about integrity of joint surfaces and extensibility of joint capsule and associated ligs
Hard end feel possibilities
- bone
Soft end feel possibilities
- soft tissue approximation (muscle)
Firm end feel possibilites
- capsular, ligament, muscle stretch
Boggy end feel possibilities
- edema, synovitis
Empty end feel possibilites
- pain
Capsular Patterns
- pathological conditions involving the entire joint capsule cause a particular pattern of restrictions involving all or most of the passive motions of the joint (capsular fibrosis and considerable effusion/synovial inflammation)
Factors affecting ROM
- age
- gender
- body mass
