TO THE EDITOR: Interpretations on the effect of estrogen/sex should be based on direct measures of muscle injury and subsequent repair/regeneration (i.e., improvements in muscle structure and function after injurious exercise). The inclusion of indexes of the inflammatory response (e.g., accumulation of neutrophils and/or macrophages) and inflammation (e.g., edema) into the discussion seems to ...

Objectives: Dry Needling (DN) is a novel and effective intervention for patients with Myofascial Pain Syndrome (MPS). Some characteristics, such as needle penetration depth, needle insertion into the target muscle, and trigger points must be identified in this intervention. The Ultrasound (US)-guided DN is a technique that involves needle insertion at the site of injury and the simulation of ti...

The hip adductor muscle group plays an important role in both movement and stability at the hip joint in many athletic pursuits. Injury to this muscle group has been reported in a number of sports, among them, ice hockey, soccer, Australian football, and swimming. The identification of muscle characteristics that predispose a muscle to injury is an important step in developing conditioning prog...

The aim of our study was to investigate the effect muscle-specific fatigue quadriceps and hamstring muscles on biomechanical factors anterior cruciate ligament (ACL) injury using musculoskeletal modeling techniques during directional diversion maneuver. Fifteen female subjects performed a maneuver under three treatment conditions (quadriceps fatigue, control gait). Data from 3D motion capture s...

Skeletal muscle injuries are the most common sports-related injuries in sports medicine. In this work, we have generated a new surgically-induced skeletal muscle injury in rats, by using a biopsy needle, which could be easily reproduced and highly mimics skeletal muscle lesions detected in human athletes. By means of histology, immunofluorescence and MRI imaging, we corroborated that our model ...

INTRODUCTION Endoscopic surgical techniques improve the surgeon's view of sinus structures but are subject to extraocular muscle complications that cause permanent diplopia. METHODS A series of 15 patients with strabismus following endoscopic sinus surgery was reviewed retrospectively to characterize the type of muscle injury and report the results of surgical correction. RESULTS A variety ...

Recently, the use of hyperbaric oxygen (HBO) treatments by elite athletes to accelerate recovery from muscle injuries has become increasingly popular. However, the mechanism of promoting muscle regeneration under HBO conditions has not yet been defined. In this study, we investigated whether HBO treatments promoted muscle regeneration and modulated muscle regulatory factor expression in a rat s...

PURPOSE Doxorubicin is effective in permanently removing muscle after direct injection into the eyelid for treatment of blepharospasm and hemifacial spasm. However, patients often require two or more injection series before full abatement of their spasms is achieved. Local anesthetics cause muscle necrosis, followed by regeneration, a process that requires activation and division of muscle sate...
