W. Curt LaFrance, Jr., MD, MPH The Hoover sign has been used since 1908 to aid in diagnosing conversion paralysis in unilateral lower extremity weakness. The abductor sign tests the same finding in the horizontal plane.1 Recently the Spinal Injuries Center (SIC) test has been shown to be a highly sensitive and specific sign for lower extremity weakness.2 Patients who are unable to raise their k...

UNLABELLED A poorly understood aspect of deaf people (DP) is how their emotional information is processed. Verbal ability is key to improve emotional knowledge in people. Nevertheless, DP are unable to distinguish intonation, intensity, and the rhythm of language due to lack of hearing. Some DP have acquired both lip-reading abilities and sign language, but others have developed only sign langu...

BACKGROUND The lever sign test is a new physical examination tool to diagnose anterior cruciate ligament (ACL) tears. Preliminary results suggest almost 100% sensitivity and specificity to diagnose acute and chronic complete ACL tears and clinically significant partial tears as compared with magnetic resonance imaging (MRI). PURPOSE To assess the sensitivity and specificity of the lever sign ...

The study was conducted to: determine the critical thinking skills of students before and after being taught with guided inquiry learning model assisted by three tier test, direct instruction differences in who are using test model. This type research is a quasi-experimental design nonequivalent control group design. at MAN Pinrang population all class XI MIPA Pinrang. number samples taken 22 (...

It is known that sequential signal detection based on the sequential probability ratio test (SPRT) is the shortest on an average among other tests. Most of the work in sequential signal detection assumes independent, identically distributed noise. The decision thresholds are not exact. This is due to the complexity involved in doing an exact analysis of the sequential detector. In this paper, w...

BACKGROUND In healthcare research, outcomes with skewed probability distributions are common. Sample size calculations for such outcomes are typically based on estimates on a transformed scale (e.g. log) which may sometimes be difficult to obtain. In contrast, estimates of median and variance on the untransformed scale are generally easier to pre-specify. The aim of this paper is to describe ho...
