This paper presents a proposed quality assurance (QA) program for chiropractors using surface electromyography (sEMG) in their offices. The paper examines in detail the various aspects of the program including both the technical and professional components. The technical component has three sub topics: equipment, technical procedures, and data processing; as does the professional component: qualification/certification, compliance/peer review, and patient selection. These are also further broken down to discuss the aspects dealing with quality and also other basic components necessary to understand the effective use of sEMG in the chiropractic office.

Significant differences in surface electromyography (sEMG) have been reported between persons with low back pain (LBP) and normal, healthy controls. This manuscript presents a systematic meta-analytic review of studies examining sEMG differences between these groups. Forty-four articles were identified using MEDLINE and a review of references lists in articles. For static sEMG, the largest effect size was observed for sEMG while standing, with subjects having LBP demonstrating higher sEMG. Perspective: sEMG is a simple and non-invasive measure of muscle activity and sEMG measures hold promise as an objective marker of LBP. Read More » |

Piano students working to improve technique often practice the same passage over and over to achieve accuracy, increase speed, or perfect interpretive nuance. However, without proper skeletal alignment of hands, arms, and shoulders, and balance between the muscles involved, such repetition may lead to difficulties with, rather than mastery of, technique and stylistic interpretation and even physical injury. Surface electromyography (sEMG) is one of the variety of technologies that have been developed to monitor muscle balance, with others to monitor skeletal alignment, that serve to help students and teachers make needed corrections during performance by providing immediate biofeedback. This paper describes and illustrates a multimodal use of these biofeedback technologies and the powerful advantages of such a multimodal approach in making the student and teacher not only aware of improper alignments and balances in real time (or for later review) but also aware of approaches to correct them and improve musical outcome.

Surface electromyography (sEMG) is a technique whereby voltage-measuring electrodes attached to the surface of the skin are used to detect and/or infer various phenomena relating to muscular contractions. The development of sophisticated electronic instrumentation has permitted the use of sEMG in most areas of ergonomic research and analysis involving muscle activity. The chapters that make up this publication represent the expert opinions of the individual scientists who authored them, derived from their own clinical practice and evaluation of the literature.

A review of the relevant literature and legal precedence. This letter was written to establish the validity of Dynamic Surface EMG Technology and to respond to claims that the technology is experimental or investigational. Based upon such claims, it is clear that the issue here is one of miscommunication or lack of thorough investigation, as there is no question that significant peer-reviewed literature does exist and there is even a superior court decision supporting that the technology is in fact valid based upon the scientific literature. This correspondance cites medical literature and medical precedence which prove that such claims are unjustified, and is in fact false. Additionally, the American Medical Association (AMA) has provided a CPT code for billing sEMG, also supporting the validity of sEMG. The American Medical Association has determined that Dynamic Surface Electromyography is an insurance reimbursable procedure which is generally accepted in the medical community. Read More » |
