The purposes of this study were to assess the intertester reliability of goniometric measurements at the knee and the validity of the clinical measurements by comparing them to measurements taken from roentgenograms. Thirty healthy subjects between the ages of 20 and 60 years were studied. The subjects were positioned on their right side on a(More)
A BIST method to measure jitter without external references is presented. Measured data from 0.25-µm BiCMOS chips show jitter resolution about 30 to 50 ps over 8 cycles of a 1 GHz input signal. 1. Introduction Data communication systems and microprocessor speeds are moving into the GHz range. With the increase in data rates, it is becoming more difficult to(More)
This study was conducted to examine the validity and reliability of the leg length measurements with a tape measure. The purpose of this study was to determine: 1) the validity of the leg length measurements through comparison with x-rays, and 2) the intertester reliability. Thirty healthy subjects between the ages of 18 and 65 were studied. Each subject(More)
The mechanical aspects of delivering a baseball pitch are presented. To organize the sequence of events involved in pitching, the kinematics are.explained by the phases the pitcher passes through during the delivery. There are four categories of delivering a pitch. Each type of delivery has its own peculiar trunk actions and results in a definite and(More)
