Trigger Point Injection for Myofascial Pain Syndrome of the Low Back: A Partially Blinded Three-Arm Randomized Controlled Trial.

Study Objective: Low back pain is a common complaint in the emergency department (ED), often attributed to myofascial pain syndrome. Prior studies demonstrate trigger point injection efficacy in the ED in various body distributions, but only one has specifically assessed myofascial low back pain, and none have evaluated functional outcomes. The purpose of this study was to compare the efficacy of trigger point injections and standard therapy compared with standard therapy alone.

Special Forces Medics Ability to Identify Wooden Foreign Bodies by Point-of-Care Ultrasound.

Background: Detection of retained foreign bodies (FB) is a difficult task in both austere environments and emergency departments, particularly when they are radiolucent and not detectable by plain radiographs. Failure to identify and remove them can lead to increased morbidity.

Objective: To determine the accuracy of Special Forces (SF) medics in detecting wooden FBs in tissue models, using point-of-care ultrasound.
