OBJECTIVE: The purpose of this study was to systematically review the literature for the consequences Traumatic brain injury (TBI) has on cognitive, psychological, physical, and sports-related functioning in professional American Football players. DATA SOURCES: We performed a systematic search in 2 databases, PubMed and SPORTDiscus, to obtain literature from January 1990 to January 2015. To be eligible for inclusion, a study had to examine the relationship between TBI and the consequences for several aspects of functioning in professional American football players older than 18 years...

INTRODUCTION: The autonomic system and sympathetic activation appears integral in the pathogenesis of acute mountain sickness (AMS) at high altitude (HA), yet a link between heart rate variability (HRV) and AMS has not been convincingly shown. In this study we investigated the utility of the smartphone-derived HRV score to predict and diagnose AMS at HA. METHODS: Twenty-one healthy adults were investigated at baseline at 1400 m and over 10 days during a trek to 5140 m...

The American Medical Society for Sports Medicine (AMSSM) recognizes a need to provide direction and continually enhance the quality of sports medicine fellowship training programs. This document was developed to be an educational resource for sports medicine physicians who teach in a 1-year primary care sports medicine fellowship training program. It is meant to provide high standards and targets for fellowship training programs that choose to reassess their curriculum and seek to make improvements.

INTRODUCTION: Quadriceps strength after arthroscopic knee procedures is frequently diminished several years postoperation. Blood flow restriction (BFR) training uses partial venous occlusion while performing submaximal exercise to induce muscle hypertrophy and strength improvements. The purpose of this study was to evaluate BFR as a postoperative therapeutic intervention after knee arthroscopy. METHODS: A randomized controlled pilot study comparing physical therapy with and without BFR after knee arthroscopy was conducted...

OBJECTIVE: This study aimed to compare the immediate analgesic effects of 2 resistance programs in in-season athletes with patellar tendinopathy (PT). Resistance training is noninvasive, a principle stimulus for corticospinal and neuromuscular adaptation, and may be analgesic. DESIGN: Within-season randomized clinical trial. Data analysis was conducted blinded to group. SETTING: Subelite volleyball and basketball competitions. PARTICIPANTS: Twenty jumping athletes aged more than 16 years, participating in games/trainings 3 times per week with clinically diagnosed PT...

OBJECTIVE: Adhesive capsulitis is a self-limiting condition in a majority of patients and is often treated nonoperatively. However, symptoms may take 2 to 3 years to resolve fully. A small, but significant, portion of patients require surgical intervention. The purpose of this systematic review is to evaluate the efficacy of corticosteroid injections for the treatment of adhesive capsulitis (AC). DATA SOURCES: A review of articles indexed by the United States National Library of Medicine was conducted by querying the PubMed database for studies involving participants with AC, frozen shoulder, stiff shoulder, or painful shoulder...

OBJECTIVE: The efficacy of kinesiology taping in arthroscopic knee surgery has not been reported. The objective of this study is to investigate the efficacy of kinesiology taping in the early postoperative phase after anterior cruciate ligament reconstruction (ACLR). We hypothesized that kinesiology taping reduces knee pain and swelling and improves knee range of movement and functional outcome. DESIGN: Randomized controlled study.

OBJECTIVE: To assess heart rate variability (HRV) in athletes with concussion across three phases of recovery. DESIGN: A prospective matched control group design included the collection of HRV and symptoms measured by the Rivermead Post-Concussion Questionnaire. These measures were taken at 3 phases of recovery [(1) symptomatic; (2). asymptomatic; and (3) one-week after return-to-play (RTP)]. The same protocol was completed by noninjured athletes. SETTING: Interuniversity sports teams at a single institution...

Subclavius posticus muscle is a supernumerary anatomical variation of the subclavius muscle. The aim of this study was to show the possible contribution of the posticus muscle in the development of unilateral thoracic outlet syndrome (TOS) in overhead athletes, presenting hypertrophy of the dominant arm due to their sport activity. Reported here are 2 young overhead athletes complaining pain, paresthesia, weakness in the dominant upper limb, although presenting none of the main shoulder and neurological disorders...
