Abstract
A study has shown the potential of rotational movement in increasing arterial blood pressure during shoulder motion (Sheriff et al,2009). The aim is to investigate the effect of motion on simulated arterial pressure during walking. Ten participants walked while wearing mid‐thigh and mid‐shank mounted strain gauges connected to water filled tubes and bony landmark markers. Pressure measured during walking by the strain gauges ranged from 0 to 130mmHg. Pressure measurements fluctuated during the gait cycle with minimums during mid‐stance and swing and peaks during early stance and swing. A kinematic model was used to evaluate the influence of different movement components on the pressure measurements. The measured and calculated pressures were found to have similar profiles with slightly different averages (measured:55mmHg; calculated:60mmHg, p=0.08). The orthostatic pressure component has a large contribution with movement related pressures having both positive and negative effects. This study shows the interaction between the different components in modulating arterial pressure and the need to investigate these mechanisms in order to optimize exercise in conditions like peripheral artery disease.
