Improving Health Literacy As A Method Of Increasing Adherence In Institutionalized Geriatric Physical Therapy Patients, Kathryn Grace Stoehr Tiemessen

Graduate Student Theses, Dissertations, & Professional Papers

The global population of long-term care facility (LTCF) residents > 65 years of age has high rates of sedentary behavior, and is expected to increase in number in the coming years. LTCF residents benefit from physical therapy, which can increase patients’ activity levels while treating symptoms of the inevitable aging process. A novel method is needed to increase LTCF resident adherence to physical therapy programs (PTPs). Health literacy (HL), which is the ability to interpret and understand health related information, presents as one such method to increase patient adherence. The geriatric population has the lowest HL rates out of all adult …

When Task Constraints Delimit Movement Strategy: Implications For Isolated Joint Training In Dancers, Paige E. Rice, Sophia Nimphius

Research outputs 2014 to 2021

Athletic performance is determined by numerous variables that cannot always be controlled or modified. Due to aesthetic requirements during sports such as dance, body alignment constrains possible movement solutions. Increased power transference around the ankle-joint, coupled with lower hip-joint power, has become a preferential strategy in dancers during leaps and may be considered a dance-specific stretch-shortening cycle (SSC) demand. Newell's theoretical model of interacting constraints includes organismic (or individual), environmental, and task constraints describing the different endogenous and exogenous constraints individuals must overcome for movement and athletic performance. The unique task constraints imposed during dance will be used as a …
