The Immediate Cardiovascular Response To Joint Mobilization Of The Neck - A Randomized, Placebo-Controlled Trial In Pain-Free Adults, Emmanuel Yung, Cheongeun Oh, Michael Wong, Jason K. Grimes, Erica M. Barton, Muhammad I. Ali, David A. Cameron

All PTHMS Faculty Publications

Background: Some normotensive patients can have a spike in resting systolic blood pressure (SBP) in response to acute neck pain. Applying the typical dosage of mobilization may potentially result in a sympatho-excitatory response, further increasing resting SBP. Therefore, there is a need to explore other dosage regimens that could result in a decrease in SBP.

Objectives: To compare the blood pressure (BP) and heart rate (HR) response of pain-free, normotensive adults when receiving unilateral posterior-to-anterior mobilization (PA) applied to the neck versus its corresponding placebo (PA-P).

Study design: Double-Blind, Randomized Clinical Trial.

Emerging Trends For Continuing Education In Athletic Training, Gail Samdperil

All PTHMS Faculty Publications

The current movement in continuing professional development (CPD) embraces the concept of life-long learning, with the ultimate goal of positively influencing patient outcomes. Research has demonstrated that traditional methods of continuing education (CE) do not meet the professional needs of health care providers in terms of having a positive influence on patient care or cultivating life-long learning. Rather than to simply encourage clinicians to attend an organized or structured continuing education activity, the trend in CPD is to cultivate a more engaged participant who selects learning opportunities in a self-directed and purposeful way, depending on his or her individual educational …
