It was named for Edgar Van Nuys Allen, who described the original version of the test in 1942. [1] An altered test, first suggested by Irving S Wright in 1952, has almost universally replaced the original method in contemporary medical practice. The alternative method is often referred to as the modified Allen's test or modified Allen test. [2]

The modified Allan variance (MVAR), [2] also known as mod σ y 2 (τ), is a variable bandwidth modified variant of Allan variance, a measurement of frequency stability in clocks, oscillators and amplifiers. Its main advantage relative to Allan variance is its ability to separate white phase noise from flicker phase noise.
During an interval of time τ, as measured by the reference clock, the clock under test advances by τy, where y is the average (relative) clock frequency over that interval. If we measure two consecutive intervals as shown, we can get a value of ( y − y ′ ) 2 —a smaller value indicates a more stable and precise clock.
The modified Bruce Protocol is an alteration in the protocol so that the treadmill is initially horizontal rather than uphill, with the 1st few intervals increasing the treadmill slope only. [ 3 ] The Bruce treadmill test estimates maximum oxygen uptake using a formula and the performance of the subject on a treadmill as the workload is increased.
Buerger's test is performed in an assessment of arterial sufficiency. It is named after Leo Buerger . The vascular angle , which is also called Buerger's angle , is the angle to which the leg has to be raised before it becomes pale, whilst lying down .
The test was developed at Harvard University in 1942. [3] Several modified versions of the original Harvard step test exist; examples include the Tecumseh step test and the Kasch step test. [5] Another modified version, the Sharkey step test, was developed in the 1970s for use by the United States Forest Service at the University of Montana in ...
The Tecumseh step test is an exercise test that researchers use to determine a person's cardiovascular fitness level. The Tecumseh step test is a modified version of the Harvard Step Test, [1] and was developed by Professor Henry J. Montoye at the Department of Epidemiology, School of Public Health, University of Michigan. The main differences ...
