MHealth devices demonstrate validity and reliability in detecting steps in chronic stroke survivors who rely on assistive devices.

Purpose: To assess the concurrent validity and reliability of five mHealth devices (STEPZ, Health, Pacer, Google Fit, and Fitbit Inc.®) in counting steps among individuals with chronic stroke using assistive devices (AD). Our primary objective was to identify significant variations in step counts between AD users and non-users.

Aortic pulse wave analysis and functional capacity of heart transplantation candidates: a pilot study.

We compared cardiovascular parameters obtained with the Mobil-O-Graph and functional capacity assessed by the Duke Activity Status Index (DASI) before and after Heart Transplantation (HT) and also compared the cardiovascular parameters and the functional capacity of candidates for HT with a control group. Peripheral and central vascular pressures increased after surgery. Similar results were observed in cardiac output and pulse wave velocity.
