We are currently recruiting volunteers who are interested in participating in a brain-spinal cord-muscle response training study that aims to better understand the changes that take place in the nervous system as a result of this type of training. After spinal cord injury, brain-to-muscle connections are often interrupted. Because these connections are important in movement control, when they are not working well, movements may be disturbed. Researchers have found that people can learn to strengthen these connections through training. Strengthening these connections may be able to improve movement control and recovery after injuries.
Research participants will be asked to stand, sit, and walk during the study sessions. Electrodes are placed on the skin over leg muscles for monitoring muscle activity. For examining brain-to-muscle connections, we use transcranial magnetic stimulation. The stimulation is applied over the head and will indirectly stimulate brain cells with little or no discomfort.
Participation in this study requires approximately three sessions per week for four months, followed by two to three sessions over another three months. Each session lasts approximately 1 hour. Participants will receive a mileage reimbursement.
The purpose of this study is to determine if 3-dimensional finger force training is an effective tool in restoring hand function post stroke. Persons who survived a stroke 3 to 9 months ago and have a hand impairment will be eligible to participate in this study. Participants will be asked to come to the laboratory to practice controlling the finger force generation 3 times a week for 6 weeks. Participants will see their performance on a computer screen. Participants will also come to the laboratory for additional 4-7 visits for assessments of their upper extremity function. The total duration of the study will be 2.5 months.
Post-stroke hand impairment diminishes stroke survivors' ability to perform activities of daily living. Motor recovery has been shown to improve through peripheral sensory stimulation. This study aims to determine if vibration from a smartwatch improves post-stroke hand function.
This study explores the use of a new form of neuromodulation known as transcutaneous auricular vagus nerve stimulation (taVNS) which stimulates the ear. This stimulation will be delivered concurrently with upper limb motor rehabilitation training (3 days/week for 4 weeks) in chronic stroke patients. Patients will undergo a series of baseline assessments (including a brain scan), a 4-week course of motor rehabilitation, and post-assessments (including a second brain scan).
The objective is to determine if continuous use of TheraBracelet in the home has a clinically meaningful effect in chronic stroke survivors. The study design is a double-blinded randomized controlled trial. We will enroll 40 chronic stroke survivors with moderate hand impairment. Subjects will be randomly assigned to the treatment or control group (n=20 per group). All subjects will wear the TheraBracelet device on the paretic wrist for 8 hours/day every day during their normal daily activity for 1 month. The device will deliver vibration (treatment) or no vibration (control). Double-blinding is possible because the treatment vibration is imperceptible (i.e., subthreshold). Measures of neural plasticity, the amount of the paretic arm use in daily living, clinical hand function, biomechanical grip control, and self-reported abilities for activities of daily living will be assessed at baseline, once a week during the month of wearing the device, and for 3-month follow-up, allowing determination of the efficacy and persistence.
This research is being done to find out if brain stimulation combined with a rehabilitation therapy improves arm weakness as a result of having a stroke. The stimulation technique is called transcranial direct current stimulation (tDCS). The treatment uses direct electrical currents to stimulate specific parts of the brain. The rehabilitation therapy is called "modified Constraint Induced Movement Therapy" (mCIMT). During this rehabilitation therapy study participants will wear a mitt on the hand of the arm that was not affected by their stroke. It is designed to restrain the use of the unaffected arm, while performing therapy with impaired one.
It is not known if brain stimulation combined with rehabilitation therapy will improve arm weakness. Study participants will receive rehabilitation therapy while on this study. Study participants may or may not receive the brain stimulation therapy.
Stroke survivors with arm paresis because of stroke use their "good" arm for daily activities, but in doing so may be self-limiting their own recovery of the "bad" arm. Traditional models of stroke rehabilitation fail to fully engage the survivor and care partner(s) in actively planning post-discharge habits that improve their capacity to live well over their entire lives. This study will test a cutting-edge in-person therapy + online training program designed to progressively transfer the responsibility of driving post-stroke recovery from the therapist to the survivor.
Walking after a lower extremity amputation is often difficult. It is important that researchers and clinicians understand the mechanisms that inhibit normal walking function. In this study, we are recruiting individuals with lower extremity limb loss for a walking and balance investigation. We will also be studying matched healthy controls to do similar study procedures. All study procedures will occur on the campus of MUSC by a licensed Physical Therapist and experienced researcher. Any questions should be directed to the coordinator listed.
The purpose of this research study is to determine if it is helpful to provide a peer-supported, health promotion intervention, known as PHOENIX, for people with spinal cord injury using telehealth. An additional purpose of this research is to test if PHOENIX has an effect on community participation, quality of life, and prevention of secondary conditions, such as pressure injuries and urinary tract infections, in people with spinal cord injury. Participants in PHOENIX will complete a 16-week spinal cord injury self-management program using iPads, provided by the study, to access online educational content and participate in video visits (weekly for the first 8 weeks, then every other week for the last 8 weeks) with a peer mentor who also has a spinal cord injury. There are 12 video visits in total and each visit will take about 1 hour. Participants will also be asked to complete a series of questionnaires several times while enrolled in the study. Participants will also be asked to take part in a group discussion or an interview to provide feedback on the PHOENIX program at the end of the study.
Depression contributes directly to disability following a stroke and is the single strongest predictor of quality of life. Treatment of depressive symptoms is associated with better functional recovery and return to activities of daily living. Resistance training can effectively improve post-stroke mobility and has the potential to serve as an alternative (non-drug) anti-depressant treatment option. The purpose of this study is to assess the effects of resistance training on post-stroke depressive symptoms.
