SF is determined by measuring the difference between two threshold measurements at 10 different points across the entire field during the same test.
Psychophysical measures by involving behavioral, verbal or motor responses could certainly impair threshold measurements in different populations such as that we studied.
Lapses, or misreporting errors, can affect accuracy of threshold measurements.
No significant change in pressure pain threshold measurements was found between conditions.
Five threshold measurements were made, applying a series of ascending and descending stimulus intensities.
Pain threshold measurements and EMG are not recommended as clinical diagnostic tests.
To quantify factors affecting test-retest variability of threshold measurements over a series of 3 serial visual fields (VF).
To determine the predictive value and to define prognostic threshold measurements for mean ovarian volume (MOV) in patients undergoing IVF.
The changes over time in functional volume observed in the threshold measurements for the spleen were minor and not significant when comparing between day 1 and 7.
The threshold measurements were performed using the VOI tool in NEDPAS Software Tools [25] Version Built 26042009 written by R. Boellaard, VU University Medical Center, Amsterdam, The Netherlands.
Threshold measurements were performed for both kidneys and spleen using 42, 50, 60 and 70percentt of the maximum in the organ as limit.
