简要总结
The primary purpose of this study is to determine the effectiveness of the Magnetoencephalography (MEG) instrument to record electrical activity from parts of the body other than the brain. This study will examine if electrical activity from parts of the body, other than the brain, can be imaged by the MEG instrument. Finding will contribute to studies of pain, since abnormal electrical activity in skeletal muscle is the basis of pain, which can be severe, yet there is no non-invasive way to image this abnormal activity. This is particularly relevant to deep muscle pain and back pain.
