​​ Study in Parkinson Disease of Exercise Phase 3 Clinical Trial

This a multi-site study, with UC Denver being one of nearly 30 performance sites nationwide and the primary site location being Northwestern University. This Phase III clinical trial is designed to establish the efficacy of progressive high-intensity, endurance treadmill exercise to slow the progression of the signs of Parkinson's disease (PD). If successful, this study will have a significant impact on the quality of life of people with PD and their caregivers as well as public health since it will slow progression of the signs of PD. Establishing high-intensity endurance treadmill exercise as a means to slow the progression of the signs of the disease would mark a significant breakthrough in treating PD and would have a significant public health impact.
Physical Activity Behavior Change following Dysvascular Amputation​

The experience of amputation compounds the pre-existing physical inactivity of people with Diabetes and Peripheral Artery Disease. Despite the presence of recommendations for comprehensive interdisciplinary approach, focused on a return to community living, there are no guidelines to improve physical inactivity. The goal of this study is to implement a telerehabilitation component to promote physical activity during prosthetic training. 

Gait Retraining after Dysvascular Amputation

Following a dysvascular amputation, individuals often adapt their walking patterns to accommodate for loss of ankle function which can result in an asymmetrical walking pattern, negatively influencing walking efficiency and disability. The purpose of this study is to determine if the use of error-augmentation gait training using the split-belt treadmill or error-correction using prompts from a metronome improves gait symmetry in people who have experienced a dysvascular amputation. 

Optimizing Physical Activity Outcomes after Total Knee Arthroplasty​
​While total knee arthroplasty improves the pain and disability associated with knee osteoarthritis, physical activity levels after total knee arthroplasty remain at low levels and are nearly unchanged from before surgery. This study is assessing the efficacy of using physical activity behavior-change telerehabilitation for improving physical activity outcomes. The three-month intervention is focused on changing habitual behaviors through remote video telerehabilitation sessions between participants and physical therapists.

Personalized Reference Charts for Prosthetic Rehabilitation​
​A one-size-fits-all approach to prosthetic rehabilitation does not take into account differences in age, cause of amputation, or physical activity before amputation. Working with non-traumatic lower limb amputation and health care providers such as physical therapists and prosthetists, we will begin to develop personalized reference charts to enable precise goal-setting and targeted monitoring. The “patients-like-me” approach has been developed for recovery after total knee arthroplasty and is being adapted to people with lower limb amputation.
