After spinal cord injury, stroke or other traumatic events to the nervous system, reflex functions often change. Because reflexes play an important part in movement and behavior, when reflexes are not working well, movements may be disturbed.  Researchers have found that people can learn to increase or decrease a reflex response by means of training. Learning to change a reflex response may become an effective approach as a rehabilitation treatment.

Research participants will stand or sit in a chair while wearing a standard clinical EEG cap for monitoring brain activity. Surface electrodes will be placed on the skin over leg muscles for monitoring muscle activity and over a nerve to produce reflex responses. Nerve stimulation may cause a brief mild sensation. The procedure is completely harmless and non-invasive.

Participation in this study requires approximately three sessions per week for two to three months, followed by four to eight sessions over another two to three months. Each session will last approximately 90 minutes. Participants will be paid $15 per session.

Every effort will be made to accommodate the individual schedules of participants, i.e., before work, after work, lunchtime, etc. Participants should be reliable and prompt since the success of the study depends on consistent participation and it may be difficult to make up missed sessions.
