The advent of smart phones has enabled health care anywhere and anytime. With pervasive health care, a person can perform necessary day to day tasks while his health is recorded, controlled, and processed continuously using on body sensors and actuators to capture abnormalities, trends, and causes. In such a scenario, seamless operation of the pervasive health management system (PHMS), given dynamic changes in the context induced by mobility of the user is of utmost importance. Such context changes dynamically affect many aspects such as the processing requirements of the health management application, the available energy sources, the interaction between a medical device with the human body. For social acceptability of PHMSes, they have to be tested and verified for their safe, energy sustainable (long term) and reliable operation under such dynamically changing environment. This paper proposes a novel technique to analyze PHMSes under mobility induced dynamic changes in the context and constant interaction of the medical device with the human body. Results show that human mobility induced context changes can cause unsafe conditions such as drug overdose.
