The purpose of this study is to evaluate how certain procedures work for individuals with chronic neck pain.

Individuals who are 18 years of age or older and have chronic neck pain will participate in this study. The study involves randomly assigning individuals into two treatment groups (i.e. manual therapy and resistance exercise). Both treatments are recommended treatments and are part of clinical practice guidelines and are well supported in the literature.

Participants will be asked to complete a 4-week training program which includes physical examination, education, treatment, and an exercise plan. Participants will also complete a brief set of questionnaires at their baseline visit, 4 weeks, and 6 months after their initial visit

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.

Transcranial magnetic stimulation (TMS) is a non-invasive brain stimulation method often used to assess connectivity between the brain and specific muscles. This research study is aimed at finding the changes in the manner brain communicates with leg muscles post-stroke and its effects on movement coordination during walking.

Transcranial direct current stimulation (tDCS) has shown the potential to improve symptoms in patients with motor deficits, however its effects have not been consistent in randomized studies to date, limiting widespread adoption of this technology. A critical gap in our knowledge is a detailed understanding of how tDCS affects motor areas in the brain. We propose using tDCS while recording directly from motor cortex using subdural electrocorticography (sECoG) in patients undergoing deep brain stimulation surgery. We expect this novel approach to broaden our understanding of tDCS application and possibly lead to therapeutic advances in this population.

Rehabilitation interventions including resistance training, functional and task-specific therapy, and gait or locomotor training have been shown to be successful in improving motor function in individuals with neurologic disease or injury. Recent investigations conducted in our laboratory indicate that intense resistance training coupled with task-specific functional training lead to significant gains in functional motor recovery. Similarly, gait rehabilitation involving intense treadmill training and/or task-specific locomotor training has been shown to be effective in improving locomotor ability. However, the underlying neural adaptations associated with these therapeutic approaches are not well understood. Our primary goal is to understand the motor control underpinnings of neurologic rehabilitation in order to apply this knowledge to future generations of therapeutic interventions.
