Early mobilization and exercise after surgery are crucial for reducing both postoperative complications and hospital length of stay.
The challenge is that in many cases, the prescribed exercises are not entered in the patient chart, causing confusion for both patient and staff regarding the extent to which these orders are actually followed.
One solution for this dilemma is the Activity Board, which clearly visualizes the individual exercise schedule prescribed by the physical therapist for the patient. By placing the Activity Board at the patient’s bedside, staff and patients can easily follow up at any time of day to ensure that all exercises were carried out, including on weekends and holidays when the physical therapist is not always available. The Activity Board is also appropriate for patients with other medical problems, as well as for residents of assisted living facilities who are receiving care, or individuals who live at home and are undergoing rehabilitation with the assistance of home help services.

In this episode, we are joined by Dr. Charles Hillman, a Professor in the Department of Psychology and the Department of Physical Therapy, Movement, and Rehabilitation Sciences at Northeastern University in Boston, Massachusetts. Dr. Hillman is also the co-director of the Center for Cognitive and Brain Health, which focuses on understanding how lifestyle choices and behaviors impact brain health and cognition.
Throughout his career, Dr. Hillman has published over 300 articles and co-edited a text on Functional Neuroimaging in Exercise and Sport Sciences. He has also served on numerous committees, including the Institute of Medicine of the National Academies and the Health and Human Services Physical Activity Guidelines for American's Scientific Advisory Committee.
In this conversation, we delve into Dr. Hillman's research on how lifestyle choices such as physical activity and diet impact brain health and cognitive function. We also discuss the mission of the Center for Cognitive and Brain Health and its research on how to maximize health and well-being and promote effective functioning for individuals across the lifespan.
Join us as we explore the fascinating research of Dr. Charles Hillman and his team at the Center for Cognitive and Brain Health.
