BACKGROUND: Neurogenic thoracic outlet syndrome (NTOS) results from compression of the brachial plexus by the clavicle, first rib, and scalene muscles and may develop secondary to repetitive motion of the upper extremity. Athletes routinely perform repetitive motions, and sports requiring significant arm and shoulder use may put the participant at increased risk for NTOS. Competitive athletes who develop NTOS may require first rib resection and scalenectomy (FRRS) for symptomatic relief...

BACKGROUND: Few studies have documented the outcomes of superior labral anterior-posterior (SLAP) repairs in baseball players. Furthermore, the results of these previous studies varied widely and were based on small numbers of patients. Hypothesis/Purpose: The purpose was to report return-to-play (RTP) rates and validated subjective outcome scores for baseball players after SLAP repair. It was hypothesized that RTP rates and outcomes would be significantly different between pitchers and nonpitchers, as well as among baseball levels...

BACKGROUND: It is known that the humeral retroversion of baseball players is greater in the throwing arm than in the nonthrowing arm. An investigation measuring dry bone specimens also showed that the right humerus had greater retroversion than the left. Considering these facts, it was hypothesized that humeral retroversion would differ between right- and left-handed players. This study aimed to compare the bilateral humeral retroversion between right- and left-handed skeletally mature baseball players...

CONTEXT:   Stress fractures are injuries caused by cumulative, repetitive stress that leads to abnormal bone remodeling. Specific populations, including female athletes and endurance athletes, are at higher risk than the general athletic population. Whereas more than 460 000 individuals participate in collegiate athletics in the United States, no large study has been conducted to determine the incidence of stress fractures in collegiate athletes. OBJECTIVE:   To assess the incidence of stress fractures in National Collegiate Athletic Association (NCAA) athletes and investigate rates and patterns overall and by sport...

PURPOSE: A decrease in total range of motion (ROM) of the dominant shoulder may predispose baseball athletes to increased shoulder injury risk; the most effective technique for improving ROM is unknown. The purpose of this study was to compare the immediate effects of Total Motion Release® (TMR) to a generic dynamic warm-up program in baseball athletes. METHODS: Baseball athletes (n=20) were randomly assigned to an intervention group: TMR® group (TMRG; n=10) or traditional warm-up group (TWG; n=10)...

BACKGROUND: Ulnar collateral ligament reconstruction (UCLR) has become a common procedure among baseball players of all levels. There are several graft choices in performing UCLR, one of which is a hamstring (gracilis or semitendinosus) autograft. It is unclear whether the hamstring muscle from a pitcher's drive leg (ipsilateral side of the UCLR) or landing leg (contralateral side of the UCLR) is more active during the pitching motion. We hypothesized that the landing leg semitendinosus will be more electromyographically active than the drive leg...

BACKGROUND: Professional athletes are predisposed to fractures of the foot due to large stresses placed on the lower extremity. These players are concerned with efficiently returning to play at a high level. Return-to-play rates after operative treatment have been previously reported, yet performance outcomes after such treatment are generally unknown in this population. HYPOTHESIS: Overall, professional athletes sustaining a foot fracture would return to play at high rates with little impact on post-operative performance or league participation...

High solar radiation has been recognised as a contributing factor to exertional heat-related illness in individuals exercising outdoors in the heat. Although solar radiation intensity has been known to have similar time-of-day variation as body temperature, the relationship between fluctuations in solar radiation associated with diurnal change in the angle of sunlight and thermoregulatory responses in individuals exercising outdoors in a hot environment remains largely unknown. The present study therefore investigated the time-of-day effects of variations in solar radiation associated with changing solar elevation angle on thermoregulatory responses during moderate-intensity outdoor exercise in the heat of summer...

Especial skills are skills that are distinctive by virtue of massive practice within the narrow contexts in which they are expressed. In the first demonstration of especial skills, Keetch, Schmidt, Lee, and Young (2005) showed that experienced basketball players are better at shooting baskets from the foul line, where they had massive amounts of practice, than would expected from their success at other locations closer to or farther from the basket. Similar results were obtained for baseball throwing. The authors asked whether especial skills hold in archery, a sport requiring less movement...

We examined the role that season progression and social threats play in the heat-aggression hypothesis within Major League Baseball put forward by Reifman, Larrick, and Fein (). Box score data from 38,870 Major League Baseball games between the years of 2000 and 2015 was used to test the heat-aggression relationship, while accounting for temporal and social factors that may be simultaneously exerting influence on player behavior. Controlling for a number of other variables, we observed that the effect of temperature on aggressive behavior is partially contingent on the point of the season in which the game took place...

Several attempts to identify the optimal on deck procedure to enhance swing velocity in baseball have been made. However, inconsistent findings continue to constitute much of the body of literature. Additionally, the emergence of athlete monitoring in sport has led to the exploration of more sport specific tasks to potentially identify athlete fatigue and readiness to perform. Therefore, the purpose of this investigation was to examine three different bat weight warm up protocols on subsequent swing velocity and to examine the reliability of swing velocity measurements to allude to its potential a sport specific athlete monitoring metric...

Poststroke weakness on the more-affected side may arise from reduced corticospinal drive, disuse muscle atrophy, spasticity, and abnormal coordination. This study investigated changes in muscle activation patterns to understand therapy-induced improvements in motor-function in chronic stroke compared to clinical assessments and to identify the effect of motor-function level on muscle activation changes. Electromyography (EMG) was recorded from five upper limb muscles on the more-affected side of 24 patients during early and late therapy sessions of an intensive 14-day program of Wii-based Movement Therapy (WMT) and for a subset of 13 patients at 6-month follow-up...
