Summary
Both the cumulative sum (CUSUM) error box and the t-test show good interexaminer reliability for analyzing inhibitory reflexes. These methods are comparable for assessing reflex data.
Area of Science:
- Neuroscience
- Biomedical Engineering
- Physiology
Background:
- Lack of consensus on methodologies for analyzing inhibitory reflexes.
- Commonly used methods include cumulative sum (CUSUM) error box and t-test.
- Need to assess reliability and comparability of these methods.
Purpose of the Study:
- Assess interexaminer reliability of CUSUM error box and t-test for inhibitory reflex analysis.
- Determine if CUSUM and t-test yield similar results.
- Evaluate the comparability of the two analytical methods.
Main Methods:
- Recorded inhibitory jaw reflexes from the masseter muscle.
- Applied electrical stimuli to the upper lip skin.
- Analyzed reflex data using CUSUM error box and t-test by two examiners.
- Assessed outcome variables: reflex parts, area size, and onset.
- Used intraclass correlation coefficient (ICC) for reliability and comparability assessment.
Main Results:
- Fair-to-good to excellent interexaminer reliability for both CUSUM and t-test methods.
- All tested variables showed good reliability.
- Fair-to-good comparability between the CUSUM error box and t-test methods.
Conclusions:
- Both CUSUM error box and t-test are suitable for analyzing inhibitory reflex data.
- The choice between methods can be based on reliability and comparability findings.
- Further research may explore other analytical approaches.
