The modified Allen's test is also performed prior to heart bypass surgery. The radial artery is occasionally used as a conduit for bypass surgery, and its patency lasts longer in comparison to the saphenous veins. Prior to heart bypass surgery, the test is performed to assess the suitability of the radial artery to be used as a conduit.
Watzke-Allen test is a test used in the diagnosis of a macular hole. It is a subjective test based on photoreceptor displacement. [1] Test can be used to differentiate full thickness macular hole from other similar conditions and also to assess retinal function after surgical closure of the hole. [2] [3]

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.
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 Modified Ashworth scale (MAS) measures resistance during passive soft-tissue stretching and is used as a simple measure of spasticity. [1] Scoring (taken from Bohannon and Smith, 1987): 0: No increase in muscle tone
The test has since been translated into Italian, [5] Chinese, [1] and French. [6] The scores of the scale have reported good reliability and validity across multiple study samples. [1] In a study conducted by Chinese researchers in 2009, the Modified Overt Aggression Scale was found to be both reliable and valid. [1]
Within the branch of materials science known as material failure theory, the Goodman relation (also called a Goodman diagram, a Goodman-Haigh diagram, a Haigh diagram or a Haigh-Soderberg diagram) is an equation used to quantify the interaction of mean and alternating stresses on the fatigue life of a material.
