The construct of ______ encompasses all those tasks, activities and roles that identify a person as an independent adult or as a child progressing toward adult independence

Patient referenced concept and is dependent on what the individual self identifies as essential to support physical and psychological well being, as well as to create a personal sense of meaningful living

Doing things with a purpose or movement with a purpose

Patient’s capacity to do an activity or task

Pertains to how the patient performs in his current context or situation

Pertains to patient background

Everything about the patient

External factors such as transportation, support system, laws, government, etc.

Could either be facilitator or barrier

About the patient themselves such as age, gender, education, work or occupation

Used to measure how a person does certain tasks or fulfills certain roles in the various dimensions described by the ICF

Function tests can utilize four highly divergent perspectives on what is to be tested or measured by the physical therapist

Directly affects what types of tests and measures should be chosen and what parameters of measurement are appropriate to yield data useful to making clinical judgements

Divergent perspective on what is to be tested or measure by PT

Talks about “Does this pt perform this certain activity habitually? or “Does this pt even have the capacity or is the patient even able to perform this activity?

Conducive to the type of testing and free of distractions

Should be precise and unambiguous

Testing may be biased by fatigue

Should occur at regular intervals during treatment to document progress and before discharge from the episode of care

2 types of instruments

Involves the PT observing the pt performing an activity

May be used either to describe the patient’s current level of function or to identify the maximum level of function possible

Patient is the one answering or giving data to the instrument

Patient is asked directly either by the therapist or by an interviewer or even by a self administered report instrument

Outpatient PT improvement in movement assessment log (OPTIMAL)

Instrument parameters and formats

Therapist should use terms that are well defined and unambiguous

Helpful to qualify a person’s performance by linking observations with nonspecific indicators of impairments

Time scores alone do not always yield the complete functional picture because time is different from the quality of the movement

Time does not equate to quality of performance

Checklist, scored as able to do or not aboe to do, independent or dependent, completed or incomplete, etc

Described a range of performance or the degree to which the person can perform the task; no difficulty, some difficulty, unable to do or always, sometimes, rarely, never

Visual analog scales attempt to present measurement quantities in terms of straight line placed horizontally or vertically on paper

Measure a phenomenon dependently, time after time, accurately, predictability, and without variation

Pertains to it being stable

Stable and will not indicate change when none has occurred

Tests should be performed by the same therapist of the same performance should be highly correlated

Agreement among multiple observers of the same event

Determining the quality of instruments

Multifaceted concept and established in many different ways

Validity assess:

Appear to measure what it purports to measure

Refers to the face value of the instrument

Measures all important or specified dimensions of function

Pertains to the content of the tool itself

Results compared to the gold standard

Assessment tool compared to the best tool

Degree to which two instruments agree

Refers to the portion of individuals with a limitation in function who are correctly classified

Specificity: Those who have disease or limitation of function are correctly classified

Opposite of sensitivity

Individuals who do not have limitation in function who are correctly classified

Proportion of people who have a positive findung in a test who actually have a limitation in function as classified by the comparison test

Proportion of people who have a negative finding on a test who do not have a limitation in function

Both the predictive values pertains to comparative assessment tool or the assessment tool you are complaining to that of the gold standard

Pertains to meaningful change in a patient’s status

MDC

MCID

Smallest amount of change in a measurement that exceeds the measurement error of the instrument

True change

Smallest difference in a measured variable that signifies an important rather than a trivial difference in the patient’s condition

Important change

Specific construct

Combination of these constructs or may have items from different ICF domains

Sample instruments to assess function

Positive and negative predictive values

Impairments

Tasks

Is the patient able to execute a certain activity

More or less include working

Work includes other sub activities that comprise the participation of work
