A 1951 USAF resolution test chart is a microscopic optical resolution test device originally defined by the U.S. Air Force MIL-STD-150A standard of 1951. The design provides numerous small target shapes exhibiting a stepped assortment of precise spatial frequency specimens.
Alternatively, the BBS can be used as a multilevel tool, with the risk of multiple falls increasing below a score of 45 and a significant increase below 40. [10] In the original study, the value of 45 points was used to calculate relative risk estimates to demonstrate predictive validity, [2] and a score of 45 has been shown to be an appropriate cut-off for safe independent ambulation and the ...
Posturography is the technique used to quantify postural control in upright stance in either static or dynamic conditions. Among them, Computerized dynamic posturography (CDP), also called test of balance (TOB), is a non-invasive specialized clinical assessment technique used to quantify the central nervous system adaptive mechanisms (sensory, motor and central) involved in the control of ...
Beginning in 1920, the IAAF considered, at least, the following criteria for a legitimate decathlon scoring table: [4] (1) The table should reflect the fact that, at higher levels of performance, a unit gain (such as a decrement of 0.01 second in sprint times) is more significant than at lower levels of performance, because of the physiological limitations of the human body.
In the UK, the Royal College of Physicians developed the National Early Warning Score (NEWS) in 2012 to replace local or regional scores. [16] [17] [18] The NEWS score is the largest national EWS effort to date and has been adopted by some international healthcare services. [1] A second version of the score was introduced in 2017.
Like stanines, individual sten scores are demarcated by half standard deviations. Thus, a sten score of 5 includes all standard scores from -.5 to zero and is centered at -0.25 and a sten score of 4 includes all standard scores from -1.0 to -0.5 and is centered at -0.75. A sten score of 1 includes all standard scores below -2.0.

The first issue with the original scale was that the standardization sample was quite inadequate. Secondly, there was no evidence of reliability or validity in the test manual. Third, the test directions were sometimes vague and scoring procedures questionable.
