وفيها كلام بسيط عن inter-rater and intra-rater
وان شاء الله تفيدك في شي
Reliability is the repeatability and the extent to which comparable results are achieved every time a test is repeated. If a muscle test is repeated by one or more therapists who obtain the same grade every time; then the test is reliable. The key to reliability for manual muscle testing is to follow the standard procedures, performing the test in the same way each time and in the same way that other therapists perform it. Reliability is increased if the therapist gives clear instructions to the patient.
Evaluation procedures should exhibit inter-rater and intra-rater reliability:
* Inter-rater reliability means that another person who performs the test should arrive at the same results, to an acceptable extent.
* Intra-rater reliability means that one person should come out with the same results on every repetition of the test, within acceptable level.
There are three methods that estimate reliability of certain measurement tool; test-retest, parallel-forms and split-half methods. Inter-rater reliability test was done to examine the effects of goniometer size on the reliability of passive shoulder joint measurements. It is concluded that goniometric passive measurement of the range of the shoulder joint motion can be highly reliable when taken by a single therapist (intra-rater reliability), regardless of the size of the goniometer.
