Clinical Utilization of Surface Electromyography and Needle Electromyography: A Comparison of the Two Methodologies
Needle and surface electromyography are 2 distinct modalities. They are both electro-physiological techniques aimed at the investigation of neuromuscular dysfunction. The clinical utilization of each technique is insuffi ciently known to the nonspecialist or to the typical patient. The present article aims at presenting a succint description of each modality and the differences between the two ...
متن کاملNeedle electromyography.
Physiologic assessment of diseases of the motor unit from the anterior horn cells to the muscles relies on a combination of needle electromyography (EMG) and nerve conduction studies (NCS). Both require a unique combination of knowledge of peripheral nervous system anatomy, physiology, pathophysiology, diseases, techniques, and electricity is necessary. Successful, high-quality, reproducible EM...
متن کاملHematoma risk after needle electromyography.
INTRODUCTION Although needle electromyography (EMG) appears to be a relatively safe procedure based primarily on clinical experience, no evidence-based guidelines exist for EMG procedures in patients taking anticoagulant or antiplatelet medications. We sought to determine whether there is an increased risk of hematoma formation after EMG of potentially high-risk muscles in patients taking antic...
متن کاملSteps of the Needle Electromyography Examination
Insertional activity is examined by moving the needle through the muscle briefly and observing the crispness, size, and duration of the electrical potentials produced. These potentials are mechanically evoked injury potentials due to the advancement of the needle. After a brief, small movement of the needle, insertional activity will usually persist no more than 300 ms. However, this duration i...
متن کاملSurface Electromyography (semg)
Most practitioners would agree that the main cause of urinary incontinence after RP is sphincter or neurological damage or urethral shortening due to the surgery. The external striated sphincter is tubular and has broad attachments over the fascia of the prostate near the apex. Its innervations arise from the pudendal nerves and the autonomic nerves in the pelvic plexus. Urinary continence reco...
