By 2050, it is estimated that the number of adults in the United States over the age of 65 will double to over 83 million individuals. With this aging population, healthcare utilization will increase dramatically with concomitant demand for rehabilitation after hospitalization. For example, after some surgeries an important measure of recovery is the level of activity the individual can manage –- those who quickly demonstrate mobility have better outcomes, whereas those who having ongoing pain or other physical difficulties (e.g., limited range of motion) will need more active interventions to aid in the recovery process. Finding the best way to support patients during rehabilitation –- within a healthcare facility or at home –- without compromising safety is a significant challenge. The Center for SMART Health has ongoing collaborations with local rehabilitation centers to use sensing technologies to automatically assess inpatient recovery and their level of activity, as well as providing a level of secure, continuous vigilance via remote monitoring.
