A positive distraction test occurs when specific movements or applied pressure lead to the relief of pain, indicating potential nerve root compression or facet joint pressure.
According to the provided reference, a positive outcome for a distraction test is specifically defined by the result observed during the test:
- Key Indicator: If pain is relieved as a result of the movement or pressure applied during the test.
Understanding the Positive Result
The relief of pain during a distraction test is considered significant because it points towards specific potential causes for the patient's discomfort.
Based on the reference:
- Interpretation: A positive test result (pain relief) suggests the presence of nerve root compression and/or facet joint pressure.
- Grading: The severity or "grade" of this pressure is determined by the amount of pressure applied and the degree of pain relief experienced by the patient during the test.
In essence, a positive distraction test doesn't describe the test procedure itself, but rather the favorable response of pain reduction, which helps clinicians identify potential sources of musculoskeletal pain related to nerve roots or facet joints.
