The purpose of the study is to develop a protocol to assess blood flow in the upper limb vasculature before and after osteopathic manipulative treatment (OMT) using Pulsed-wave Doppler ultrasonography (US). We will assess the subclavian artery and vein at two locations (above and below the clavicle) and the brachial artery and vein (within the axilla) to determine the reproducibility of the blood flow findings at each location and the impact of OMT on the blood flow. Additionally we will qualitatively assess morphological changes of the brachial plexus before and after OMT with US.

Blood flow changes in the upper extremity.
Timeframe: Pre and post osteopathic manipulative treatment on the day of treatment. Pre-measurement followed by 10 minutes of rest before OMT. Post-measurement made immediately following the OMT treatment.
