Evaluating the effectiveness of a lower extremity venous phantom on developing ultrasound examination skills and confidence.

Introduction: The aims of this study were: (1) Determine the effect on student ultrasound scanning skills using a lower extremity venous ultrasound phantom in addition to standard teaching methods of didactic lecture and scanning live volunteers and (2) Determine the effect of using a lower extremity venous ultrasound phantom in addition to standard teaching methods of didactic lecture and scanning live volunteers on student confidence levels in performing the lower extremity venous ultrasound examination.

Methods: Participants were first year diagnostic medical sonography students with minimal scanning experience ( = 11), which were randomized into two groups. Group 1 ( = 5) received the standard didactic lecture and attended a scan lab assessment where they performed a lower extremity venous examination on a human volunteer.

Effectiveness of long and short bout walking on increasing physical activity in women.

Background: The accumulation of physical activity (PA) throughout the day has been suggested as a means to increase PA behavior. It is not known, however, if accumulated PA results in equivalent increases in PA behavior compared with one continuous session. The purpose of this investigation was to compare changes in PA between participants assigned to walk daily in accumulated shorter bouts vs.
