This work presents an immersive Virtual Reality (VR) system to evaluate, and potentially treat, the alterations in rhythmic hand movements seen in Parkinson's disease (PD) and the elderly (EC), by comparison with healthy young controls (YC). The system integrates the subjects into a VR environment by means of a Head Mounted Display, such that subjects perceive themselves in a virtual world cons...
21 Objective: Cardiotonic agents may differentially alter indices of the cytosolic [Ca ] / left ventricular pressure (LVP) relationship when 21 given before and after ischemia. We measured and calculated systolic–diastolic [Ca ], systolic–diastolic LVP, velocity ratios (VRs) 21 21 21 d[Ca ] /dt to dLVP/dt (VR ), d[Ca ] /dt to dLVP/dt (VR ), and area ratio (AR, area Ca ] /area LVP per beat) befo...
