Abstract:Objectives: The aim of this study was to determine changes in axillary artery diameter and peak systolic velocity in asymptomatic individuals during upper limb positioning commonly used to assess vascular pathology in athletes. Design: Repeated measures observational study. Setting: Physiology laboratory. Participants: Subjective and objective screening excluded individuals with past, or present, conditions related to neurovascular compression syndromes. Thirty-one subjects (21 females, 10 males; mean age: 257… Show more
“…For practical reasons the test positions of the Doppler and strength measurements were similar but not identical. Since it has been shown that changes in arm position may influence axillary blood flow [38], we cannot completely rule out haemodynamic differences between positions.…”

“…Stapleton et al [12] performed a study to evaluate for changes in axillary artery diameter and peak systolic velocity in subjects with-out symptoms during upper limb positioning with the arm in ABER, a position commonly used during physical examinations of athletes to assess for vascular abnormalities and referred to as the hyperabduction maneuver. Those investigators found statistically significant reductions in axillary artery diameter only during extreme (120°) abduction without shoulder symptoms.…”
Positional MRI and ultrasound are highly useful in evaluation of the shoulder. Knowledge of the normal appearance of anatomic structures and pathologic changes in nontraditional imaging planes is necessary to avoid pitfalls in interpretation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
