Reliability
|
The degree to which a measurement is error-free
OR -- the consistency of a measurement |
|
|
4 Types of reliability
|
Intratester reliability
Intertester Parallel (Alternate) forms Population specific |
|
|
Parallel forms of reliability
|
The consistency or agreement of measurements obtained using different forms of a test. Indicates whether different forms of the same test can be used interchangably
|
|
|
Population specific reliability means
|
The consistency of a measurement within a defined population of subjects, ex: ROM on knees of those with rheumatoid arthritis
|
|
|
Validity
|
The degree to which a useful interpretation can be made from a measurement
|
|
|
Construct validity
|
Theoretical form of validity, based on logical argument (theoretical and research evidence)that supports the idea that a measurement reflects what we want it to measure
|
|
|
Content validity
|
A theoretical form of validity that addresses whether a test reflects the variable as we have defined it. does the measurement reflect all the meaningful elements of a construct and no extraneous elements.
|
|
|
Criterion related validities are forms of validity demonstrated through
|
direct research
|
|
|
Concurrent validity
|
An inference in justified by comparing a measurement to supporting evidence that was obtained at approximately the same time -- usually one measurement compared to another
|
|
|
Predictive validity
|
examines the justification of using a measurement to say something about future events
|
|
|
Prescriptive Validity
|
The inference is justified based on the sucessful outcome of the chosen treatment.
|
|
|
Internal Validity
|
Whether changes in the outcome measurements (the dependent variables) are due to the treatment (the dependent variables). This is essential for any research
|
|
|
External validity
|
Whether results may be generalized beyond the conditions of the study. May be compromised by the type of patient group used in the study.
|
|
|
Capsular pattern
|
A limitation of movement in a joint which occurs in a predictable pattern.
|
|
|
Three premises of Cyriax
|
1. All pain is from a lesion
2. All treatment must reach the lesion 3. All treatment must exert a beneficial effect on the lesion |
|
|
Inert tissue is
|
Tissue not capable of producing tension
|
|
|
Four types of contractile tissue
|
muscle, tendon, musculotendonous junction, osseotendonous junction
|
|
|
Cyriax does not believe ___ is useful, and may be misleading
|
Palpations
|
|
|
Cyriax believes the majority of spinal problems are due to the
|
intervertebral disc
|
|
|
Cyriax claims the trigger areas are ___
|
secondary effect of pressure on the dura from a herniated disc
|
|
|
Muscle spasm
|
An increase in the turgor or hardness of a muscle
|
|
|
Cyriax does not feel that spinal pain originates from the
|
many ligaments and facet joints in the spine, all of which are innervated
|
|
|
Trigger area
|
An area of tenderness in a muscle region that when palpated reproduces the patient's pain complaints
|
