Research shows that exercising at home can improve arm and hand movement after a stroke. Unfortunately, it can be hard to exercise enough to make a difference in arm and hand movement after stroke. In this study, we will try to determine things that make it easy or hard for Veterans to exercise their arm and hand after a stroke. In this study, we will recruit Veteran stroke survivors who have difficulty using their arm and hand after a stroke. First, we will administer surveys and questionnaires to get Veteran stroke survivors' perspectives on their self-confidence, mood, sleep, and more. Then, we will ask them to track their home exercise using a wearable movement tracker (like a smart watch). Then, Veteran stroke survivors will meet with a researcher to talk about their experience doing home exercise and why they think it was easy or hard to do.

This small stroke rehabilitation study will test the feasibility of a new method to personalize a home exercise program for arm/hand recovery. The research study will last ~8 weeks. Participants will be included if they are adults who have experienced a stroke that has caused one arm/hand to become weak, are able to come to the MUSC main campus 3 times for ~2hr arm movement evaluations, and are willing and able to engage in 60 minute telerehabilitation video visits with an occupational therapist 1-2 times per week for 6 weeks. We anticipate that the results of this study will enable occupational therapists and stroke survivors to, together, design home exercise programs that are meaningful, motivating and effective.

Newborns who are born premature or suffer brain injury at birth are at risk for motor problems that may cause weakness in reaching and grasping on one side of the body. In older children, therapists may use a hand mitt and restraint for the stronger arm, to encourage use of the weaker side, called constraint-induced movement therapy (CIMT). Even with the high intensity therapy of CIMT, it typically takes between 40-120 hours total treatment time for most children to improve their motor skills. A non-invasive form of nerve stimulation, transcutaneous auricular vagus nerve stimulation (taVNS), stimulates a nerve by the ear that enhances learning motor skills. taVNS stimulation will be triggered by EMG sensors which detect muscle activity. The purpose of this study is to evaluate the safety and effectiveness of taVNS to improve motor skills when paired with CIMT in infants with one-sided weakness at 6-24 months of age.
