A newly developed stroboscopy rating form is presented. The evolution of the new form is discussed by focusing on how problems with another commonly used form led to its development. Interjudge agreement and intrajudge reliability data for the new rating form reveal that the parameters of phase closure, phase symmetry, and phase regularity remain difficult to rate even with the revised rating form.
Methods of training individuals to rate stroboscopic examinations vary widely in rating criteria, viewing times, samples, and length of training. Consequently, problems occur in both inter- and intrajudge agreement. Computer-aided instruction (CAI) provides a means to integrate and control key learning factors that facilitate learning. This study attempted to determine if CAI could train individuals to make accurate and reliable visuo-perceptual judgments of stroboscopy. Experienced and inexperienced subjects rated 45 samples before and after training. Following 4 to 5 hours of CAI training, the subjects with no previous experience demonstrated improved interjudge agreement with a panel of expert raters. The training was not effective for the experienced group. Regardless of the rater's experience, the parameters that required evaluation of movement were more difficult to rate than those requiring only an assessment of structure.
