This study evaluated the median nerve cross-sectional area and hand function of musicians and made comparisons to non-musicians. METHODS: Seventy-six participants took part in the study, 38 music students and professors in the musician group and 38 participants in the control group. Participants completed patient-reported questionnaires to assess the level of pain and hand function. Ultrasound images were collected at the carpal tunnel inlet and outlet. The median nerve cross-sectional area and the depth of the carpal tunnel were measured on ultrasound images using software imbedded in the ultrasound unit. RESULTS: Musicians showed higher levels of hand dysfunction and CTS symptoms than the non-musicians. The median nerve cross-sectional area was greater in musicians than in the non-musician group on bo...

Fatigue of the scapular stabilizing muscles resulting from repeated arm motion has been reported to alter scapular kinematics, which could result in the clinical assessment of scapular dyskinesis. The purpose of this study was to characterize the effect of repeated arm motion on the development of scapular dyskinesis. The hypothesis was that repeated arm motion will induce a subtle or obvious scapular dyskinesis. Materials and Methods: About 30 army Reserve Officer Training Corps (ROTC) cadets participated in the research study. The cadets level of shoulder function was determined using the Quick Disabilities of the Arm Shoulder and Hand and Pennsylvania Shoulder Score shoulder scores. Cadets performed an exercise protocol of 30 repetitions of weighted shoulder motion in the frontal plane. Shoulder and scapular musculature strength measurements were recorded prior to a...

Ultrasound imaging can be used to assess medial elbow stability. This study determined the effect of the elbow flexion angle on the medial elbow joint space during clinical tests of medial elbow stability. Ultrasound images of the nondominant elbow were collected during 3 tests of medial elbow stability: valgus stress test, weighted valgus test, and milking maneuver. The elbow flexion angle increased between the valgus stress test and milking maneuver. The width of the medial joint space was measured on ultrasound images collected in unstressed and stressed conditions. Across test conditions, the medial joint width was greater in the stressed condition (mean ± SD, 3.7 ± 0.1 mm) than in the unstressed condition (2.9 ± 0.09 mm). The medial elbow joint space width was less (mean difference, 0.16 ± 0.01 mm; P = .01) in the milking maneuver position compared to the valgus stress ...

A leading source of shoulder pain in upper string musicians is rotator cuff disease (RCD). Multiple factors contribute to its development. Compressive overload of the soft tissues of the subacromial space resulting from a decrease in the width of the subacromial space has been identified as an extrinsic factor contributing to RCD development. The purpose of this study was to characterize the width of the subacromial space by measuring acromial-humeral distance (AHD) of upper string musicians, while their arms are in standard playing positions. METHODS: Experienced musicians (n=23) were recruited from local communities. Shoulder ultrasound images were collected using standard imaging techniques. Images were collected and the AHD measured while the musician’s arm was in positions associated with playing the violin. RESULTS: On the right side, the arm position main effect was significant (p<0.001): th...

Median nerve and anterior interosseous nerve entrapment can occur proximal to the carpal tunnel, in the forearm and/or at the elbow. 1,2-8 To determine the location of nerve entrapment, the clinician must use a differential diagnosis approach that integrates information gained from a detailed history, clinical test results, and diagnostic test results.

Therefore, recognition of pancreatic injury in the differential diagnosis of blunt abdominal trauma is important for the athletic trainer. This report reviews a case of pancreatic traumatic injury to a teen-aged competitive soccer player and discusses pancreatic trauma and concerns that may be faced by athletic trainers in dealing with this type of injury.

In higher amounts, caffeine causes many adverse effects that are cause for concern. Purpose: Purposes of this study were to determine: (1) the amount of caffeine consumed by a sample of college students, (2) beliefs regarding caffeine consumption, (3) reported perceived benefits and adverse effects of caffeine consumption, (4) reasons for consuming caffeine, and (5) predictors of caffeine consumption. Methods: An anonymous survey was administered 300 freshmen attending a southeastern university. Results: Eighty-three percent of the students reported having at least one sign/symptom of caffeine intoxication in the past; 51% reported having at least one sign/symptom of caffeine withdrawal. Students consumed three to five times the recommended amount of caffeine. Father's social index, participation in organized activity in college and three alertness items (concentration, keep awake, wake up) were significant predictors of caffeine consumption. Discussion: Students ingested caffeine at levels that could cause negative health effects and seemed unaware of the total amount of caffeine consumed. Translation to Health Education Practice: More information about caffeine should be incorporated into health education at all levels, so students can identify and avoid negative effects along with caffeine withdrawal and addiction.
