Identifying reliable change in tactile temporal thresholds in multiple sclerosis: test-retest reliability

Area of Science:

• Neuroscience
• Clinical Neurology

Background:

• Tactile temporal thresholds are prolonged in multiple sclerosis (MS) patients compared to controls.
• These thresholds increase during MS relapses, suggesting impaired conduction in the corpus callosum.

Purpose of the Study:

• To validate tactile temporal thresholds as a reliable measure in MS.
• To assess the test-retest reliability of tactile temporal threshold measurements in MS patients.

Main Methods:

• Tactile temporal thresholds were measured in 61 MS patients across two sessions within three weeks.
• Test-retest reliability and standard error of measurement were calculated.
• A threshold for significant change beyond measurement error was determined.

Main Results:

• The measure demonstrated excellent test-retest reliability (0.93).
• A change exceeding 19 ms reliably indicates a true change beyond measurement error with 95% certainty.

Conclusions:

• Tactile temporal threshold measurement is a highly reliable outcome measure for MS.
• This method offers a precise and dependable tool for tracking changes in MS.
