Decreases in glenohumeral (GH) rotation motion and rotator cuff strength have been linked to multiple pathologies in the throwing arms of baseball pitchers, but a full understanding of the shoulder mechanisms affected by a total arc of motion deficit (TAMD) has not yet been achieved. This study was designed to...
Calcium channel blockers (CCB) was studied extensively in cardiology for their tissue
protective effect following myocardial infarction; we hypothesized that administration of
a CCB would interfere with the processes that result in exercise-induced muscle damage
(EIMD) and delayed onset muscle soreness. To investigate the effects of a CCB on a...
Despite dramatic changes in tennis equipment and technique, more than 30% of
recreational tennis players suffer from lateral elbow pain ("tennis elbow"). Certain
kinematic and electromyographic characteristics in backhand strokes have been
implicated as major factors responsible for lateral elbow pain. From a local tennis club,
22 recreational players who...
Ankle injuries comprise more than 15% of all sports injuries worldwide. The efficacy of the ankle taping for injury prevention has long been under scrutiny as numerous studies have shown that tape rapidly loses its ability to constrain ankle motion with exercise. Consequently, ankle braces (orthoses) are being used with...
Isolated injury of the anterior cruciate ligament (ACL) is less frequent and typically perceived as less severe than ACL injuries with concurrent damage to other knee stabilizing structures. The timing of the ACL reconstructive surgery is thought to be a
critical factor that affects the patient's postoperative outcome. No previous...
Throughout the various levels of baseball competition, pitchers often suffer season-ending or career-ending injuries. Significant improvements have been made in the treatment and rehabilitation of these injuries, with a lesser amount of attention given to injury prevention. The purpose of this study was to determine the effectiveness of an inseason...
Function of the shoulder complex is highly dependent on the relationship between the scapula and the humerus. Etiologies for the disruption of the glenohumeral relationship include impaired or abnormal scapular function, motion, or position. The lateral scapular slide test (LSST) has been developed as a clinical tool to assess this...
Several recent studies have revealed that high caliber European professional soccer players often have diminished levels of neurological functioning, yet no study has been able to identify the specific aspect of soccer participation responsible for these decreases. In an effort to identify a source of mild traumatic brain injury present...
The ulnar collateral ligament (UCL) is the primary restraint against valgus forces at the elbow. This structure cannot support the entire load placed upon the medial elbow during overhand throwing motions such as pitching a baseball. In this study we measured the contributions that different muscle groups make to the...
Objective: To investigate neurocognitive effects of collegiate football players as
assessed by the Standardized Assessment of Concussion (SAC™) testing battery and a
self-reported concussion symptoms checklist.
Design and Setting: We used a one-way MANOVA to evaluate differences in
SAC™ test scores between intercollegiate football players with no history of concussion...
