Theses, Dissertations and Capstones
Background: Shoulder pain is a common occurrence in the general population. Pain has been associated with shoulder impairments and pathology. Associations between shoulder limitations, impairments, and mechanisms of injury and altered scapular motion appear in the literature. Fatigue of the scapular stabilizing muscles resulting from repeated arm motion has been reported to alter scapular kinematics, which could result in shoulder pathology, especially impingement.
Purpose: The purpose of this study was to examine the effects of fatigue of the serratus anterior muscle on scapular kinematics. The hypotheses were that there would be decreased posterior tilt and decreased upward rotation during arm …
The Effects Of Flexor Pronator Mass Fatigue On Medial Elbow Stability, Nathaniel Harvey Millard
The Effects Of Flexor Pronator Mass Fatigue On Medial Elbow Stability, Nathaniel Harvey Millard
Theses, Dissertations and Capstones
Introduction: The medial elbow is supported from valgus loading with the ulnar collateral ligament (UCL), the flexor pronator mass (FPM), and the radial head. Fatigue of muscle can lead to a decrease in force production. The decrease in force production can lead to a decrease in joint stability. This study tested the effect of fatigue of the FPM muscles on the width of the medial joint space.
Methods: Thirty-one participants volunteered for this study (18 female and 12 male, 1 excluded; mean height 170.2±10.1 cm, mean weight 71.2±15.6 kg, mean age 21.53±1.87 years old). Ultrasound images of the width of …
