This video demonstrates needle electromyography on a patient with respiratory synkinesis, with a needle in the right biceps brachii muscle. The first section of the video shows a relaxed patient, with the appearance of motor units associated with the inhalation phase of breathing. Next, the electromyographer asks her to take a deep breath with subsequent activation of numerous atypical motor units, which is done three times. For the last section, the patient holds her breath, and the motor unit stops firing.
With the July issue of the Journal we are launching a new regular feature: the Video Gallery. The purpose of this Gallery is to combine text with video in the presentation and discussion of a topic of interest in musculoskeletal medicine. The first publication is authored by Chiang and collaborators who made a fantastic effort to write the text and produce the video in a relatively short period of time so we could include it in this issue of the Journal. This first “combined media publication” focus on the use of ultrasound for the examination of the rotator cuff and injection of the subacromial and subdeltoid bursa. Thanks to the effort of the Publisher LWW, the video can be accessed using your smartphone camera QR reader App to scan and capture the QR Code included with the print version of the article or by visiting our website at www.AJPMR.com. I hope you will appreciate this new feature and send us your comments and suggestions for future topics and use of electronic media.
