Thought Technology just released a free PDF biofeedback “mini-ebook” (49 pages) entitled, “Basic Of Surface Electromyography Applied To Physical Rehabilitation and Biomechanics.” Students or biofeedback clinicians that use surface electromyography (SEMG or EMG) will find this to be a fantastic free resource. Check the end of this review for a download link.
Basics of SEMG covers a range of topics that include the anatomy and physiology of relevant body muscles, the characteristics of the SEMG signal, various types of SEMG sensors and electrodes, suggested electrode placements, identification of artifacts, and more. The document is very well written with beautiful drawings of the human body complete with muscle identification and suggested sensor placement, as well as great text summary charts. Of course, Thought Technology emphasizes their own software and equipment (and rightfully so) in all demonstrations, but most of the concepts apply equally well to other biofeedback equipment.
