Biomechanical analyses suggest that the loss of neuromuscular control is associated with noncontact anterior cruciate ligament sprains; however, previous research has not explored link between neurocognitive function and unintentional knee injuries.To determine if athletes who suffer a injury demonstrate decreased baseline performance when compared matched controls.Case study; Level evidence, 3.The scores from computerized test battery (ImPACT) were analyzed to compare verbal memory, visual...

Purpose: Recent epidemiological research has revealed that gender differences exist in concussion incidence but no study investigated why females may be at greater risk of concussion. Our purpose was to determine whether existed head–neck segment kinematic and neuromuscular control variables responses an external force application with without neck muscle preactivation. Methods: Forty (20 20 males) physically active volunteers participated the study. The independent were gender, (known vs...

OBJECTIVE Our purpose was to determine whether sex differences exist with respect post-concussion symptoms and neurocognitive function in concussed collegiate athletes. METHODS A prospective dependent-sample cohort design used compare baseline neuropsychological test scores endorsed as functions of serial assessment time sex. The Immediate Post-concussion Assessment Cognitive Testing (ImPACT) battery administered a multicenter analysis group 79 This computerized given the athletes during...

To investigate sex differences in baseline neuropsychological function and concussion symptoms between male female collegiate athletes.A post-test only design was used to examine test scores symptoms. A total of 1209 NCAA Division I athletes from five northeastern universities the USA completed a ImPACT test. ImPACT, computerised battery, administered during an athlete's pre-season.Female performed significantly better than on verbal memory (p = 0.001), while visual 0.001). Female endorsed...

Background: The effect of total knee arthroplasty on proprioception, kinesthesia, and postural control remains controversial. It is argued that retaining the posterior cruciate ligament may help to preserve these sensorimotor functions improve longevity prosthesis functional outcome. We performed a prospective, randomized study assess balance following with cruciate-retaining stabilized prostheses. Methods: Twenty patients scheduled undergo were randomly assigned receive either or...

Abstract The purpose of this study was to examine epidemiological trends concussions among 15 different intercollegiate sports during the 1997-1998, 1998-1999, and 1999-2000 seasons. Data were collected using National Collegiate Athletic Association (NCAA) Injury Surveillance System (ISS). For studied 3 academic years, NCAA ISS documented 3,535 team-seasons, 40,547 reportable injuries, 5,566,924 practice athlete exposures (AEs), 1,090,298 game AEs. Concussions accounted for 6.2% all reported...

Ankle instability is a costly public health concern because of the associated recurrent sprains. It evident there are neuromuscular control deficits predisposing these individuals to their ankle "giving way." Individuals with history lateral sprain, who did not develop instability, may hold key understanding proper after injury.On basis previous research, authors hypothesized that would demonstrate reduced peroneal activation, causing more inverted position ankle, before and...

ABSTRACT Purpose This study aimed to identify clinical predictors of postconcussion subsequent musculoskeletal (MSK) injuries. Methods We recruited 66 National Collegiate Athletic Association intercollegiate student-athletes with a diagnosed concussion as well 36 without concussion. All participants completed multifaceted baseline consisting 1) 22-item 0–6 self-reported symptom checklist outcomes including both the number symptoms endorsed (0–22) and 2) total score (0–132), 3) Standard...

Anterior cruciate ligament (ACL) injury disrupts static and dynamic knee restraints, compromising functional stability. Deafferentation of ACL mechan-oreceptors alters the spinal reflex pathways to motor nerves muscle spindles in addition cortical for conscious unconscious appreciation proprioception kinesthesia. These are required by feed-forward feedback neuromuscular control systems dynamically stabilize joints. Feed-forward is responsible preparatory activity, while regulates reactive...

Abstract Context: Anterior instability and impingement are common in overhead athletes have been associated with decreases internal rotation (IR) increases external (ER) motion. However, the chronology effect of different female sports on these conditions yet to be determined. Objective: To measure glenohumeral IR ER rotation, total range motion, scapular position over a single competitive season. Design: Multiple group pretest-posttest study. Setting: High school. Patients or Other...

Abstract Context: Conditions such as labral and rotator cuff injuries have been linked with decreases in glenohumeral internal-rotation increases external-rotation motion. Also, decreased internal rotation is strongly associated scapular dyskinesis. Objective: To compare healthy collegiate high school baseball players' joint range of motion position. Design: Cross-sectional study. Setting: Institutional research laboratory. Patients or Other Participants: Thirty-one male National Collegiate...

The high number of repetitions and forces associated with overhead throwing lead to anatomical adaptations, such as humeral retrotorsion posterior-capsule thickness, in elite professional baseball athletes. However, little is known about the origin progression these changes that may account for increasing trend chronic shoulder injuries youth precipitate subsequent pathologic conditions throughout a young athlete's lifetime.To investigate relationship age upper extremity dominance on...

Ankle sprains are the most common injury among physically active people, with sequelae including repeated episodes of giving way, termed functional ankle instability. Copers a cohort in research comprised those who have sprained their but not suffered any further dysfunction. The use an elastic tape, Kinesio Tape, sports medicine practice has recently gained popularity and may help improve postural control deficits related to purpose this study was examine immediate prolonged effects Taping...

Context: Current research into the etiology of joint instability has yielded inconsistent results, limiting our understanding how to prevent and treat ligamentous injury effectively. Recently, cortical reorganization was demonstrated in patients with injury; however, these neural changes have not been assessed relative laxity. Objective: The purpose current study determine if excitability inhibition occur subjects functional ankle instability, as well investigate relationship between...

Adductor strains are prevalent injuries in professional soccer. The purpose of this study is to identify further evidence characteristics associated with adductor injury. MLS and other worldwide leagues have differing styles play warranting investigation injury mechanisms. A descriptive cohort was conducted a single team the MLS. Injury data collected between 2016 2022 seasons characterize Player position type, age, previous injury, mechanism(s) (MOI) were assessed understand injured...

Background Anecdotal evidence suggests an association between glenohumeral internal rotation deficits (GIRD) and scapular dysfunction, observable alteration in the normal position or motion of scapula relation to thoracic cage. Questions/purposes We therefore hypothesized players with GIRD (15° greater) will have decreased dominant arm upward increased protraction compared baseball (14° less). Methods studied 43 no current shoulder elbow symptoms; 22 had 15° greater 21 14° less. measured...

Context: Pathologies such as anterior instability and impingement are common in baseball have been linked to decreases internal rotation (IR) concurrent increases external (ER). In addition, alterations scapular position identified this population, but the chronology of these adaptations is uncertain. Objectives: To determine whether there a change range motion after single season. Design: Prospective cohort. Setting: High school. Participants: 19 high school players (age 16.6 ± 0.8 y, mass...
