The purpose of this study is to compare balance control during a single leg squat with and without a cognitive task between individuals with a history of concussion and individuals with a history of concussion and ankle sprain. Adults with a history of concussion, history of ankle sprain, history of both, or no history of ankle sprain or concussion will be enrolled. Participants will perform twelve trials of a single leg squat, half of which include listening to and recalling a series of words. This study will allow for possible avenues of improved evaluation and rehabilitation of individuals with a history of concussion and/or ankle sprain for healthcare professionals.

The purpose of this study is to test whether a mobile app, the Digital Wellness Nurse (DWN), can help African American families with weight problems lead healthier lifestyles. Participants in this study will receive education and tips on physical activity and healthy eating through weekly videos and online meetings with a community health worker (CHW) via the DWN app. The meetings with the CHW will take place once a week for 12 weeks. During these meetings, adolescents and their caregiver will set weekly goals and have the chance to earn incentives for meeting them. While in the study, participants will be asked to wear a Fitbit to track physical activity and to complete a monthly survey about eating and physical activity habits. At the end of the study, participants will be asked to participate in a focus group and talk about their experiences with the app and the study. Participation in this study may improve physical well-being, but that cannot be guaranteed.

The purpose of the study is to examine whether certain neck strengthening exercises result in change in size of the neck muscles being targeted.

Musculoskeletal Ultrasound is a non invasive, safe tool that will be used to measure the size of certain muscles in your neck. This will allow us to determine if these muscles actually get bigger in response to targeted exercise. Muscle size is a factor associated with strength.

This study will help us tease out the time it takes to create neck muscle hypertrophy, or increase in muscle size, in order to develop effective protocols for neck strengthening which may be useful in the management of chronic neck pain.

Weakness in certain neck muscles may be associated with the development of neck pain and we hope to determine effective training protocols for these neck muscle groups.

Cardiac rehabilitation is the standard-of-care treatment option for patients with cardiovascular disease and has been shown to improve many aspects critical to patient recovery. We believe that individuals who have had a stroke need to be treated similarly. We will study the effects of a comprehensive modified cardiac rehabilitation program to determine if it can improve some of the physical and psychosocial problems common in survivors of stroke with and without depression.

This study will examine the effects of 3 different physical activity goals on arthritis-related outcomes in adults with arthritis. Participants will be randomized to either 45 minutes/week, 90 minutes/week, or 150 minutes/week. Additionally, this study will examine how daily activity can influence arthritis-related outcomes such as pain and fatigue.

Adherence to home exercise is important to achieve upper limb recovery after stroke. However, adherence is typically low. Therefore, a new home exercise program with an Apple Watch and iPhone app was created to improve adherence to upper limb exercises for stroke survivors at home. Participants will come to our lab to experience the new home exercise program. Participants who opt for home use will bring the device home to try the new home exercise program at home. The purpose of this study is for researchers to examine usability and feasibility of participants using the new home exercise program.

This study aims to identify which supplemental intervention components could be added to an online physical activity program that contribute to the greatest increases in physical activity in adults with knee replacement. The 4 supplemental intervention components include phone coaching, progress reports to physicians, tailored modules, and personalized feedback. Using the most effective components, an optimized Energize! Exercise intervention will be developed for testing in a subsequent trial.

The purpose of this study is to develop and test if upper limb task practice and muscle activity training improve upper limb function in stroke survivors. Participants will be asked to come to the laboratory 3 times a week for 6 weeks to receive upper limb task practice and/or muscle activity training. Participants will also come to the laboratory for additional 3 visits for assessments of upper extremity function. The total duration of the study will be 2.5 months.

Stroke is a leading cause of disability in the U.S. and many Veteran stroke survivors live with severe disability. Despite recent advances in rehabilitation treatments many stroke survivors have persistent physical and mental difficulties such as reduced arm and leg function, difficulty thinking, and depression.
Developing treatments that address these problems is necessary to improve long-term recovery for stroke survivors. Aerobic exercise (AEx) can improve physical and mental function, and reduce depression. Additionally, AEx may enhance physical rehabilitation by making the brain more receptive to, and consequently improving the response to a rehabilitation treatment. Therefore, combining AEx with physical rehabilitation has the potential to improve multiple parts of stroke recovery. This study will examine the effect of combining AEx with physical rehabilitation on physical and mental function in stroke survivors. By gaining a better understanding of the effects of this combined intervention we aim to advance the rehabilitative care of Veteran stroke survivors.

Hand disability after stroke has a profound negative impact on functional ability and independence. Hand therapy may be augmented with sensory stimulation for better outcomes. We have developed a novel sensory stimulation - unfelt vibration applied via a wristwatch. Participants will receive this novel stimulation with hand task practice therapy or therapy only to determine if use of this stimulation is better for recovery.
