Knee joint effusion results in quadriceps inhibition and is accompanied by increased excitability in the soleus musculature. The purpose of this study was to determine if soleus arthrogenic muscle response is regulated by pre- or post-synaptic spinal mechanisms. Ten healthy adults (two females and eight males) were measured on two occasions. At the first(More)
Arthrogenic muscle inhibition (AMI) impedes rehabilitation following knee joint injury by preventing activation of the quadriceps. AMI has been attributed to neuronal reflex activity in which altered afferent input originating from the injured joint results in a diminished efferent motor drive to the quadriceps muscles. Beginning to understand the(More)
Introduction. When using the double interval slide technique for arthroscopic repair of chronic large or massive rotator cuff tears, the posterior interval release is directed toward the scapular spine until the fat pad that protects the suprascapular nerve is reached. Injury to the suprascapular nerve can occur due to the nerve's proximity to the operative(More)
Knee joint effusion causes quadriceps inhibition and is accompanied by increased soleus muscle excitability. In order to reverse the neurological alterations that occur to the musculature following effusion, we need to understand the extent of neural involvement. Ten healthy adults were tested on two occasions; during one session, subjects had their knees(More)
BACKGROUND Ulnar collateral ligament reconstruction (UCLR) is commonly performed in Major League Baseball (MLB) pitchers, but little is known about the preoperative pitch type and velocity characteristics of pitchers who go on to undergo UCLR. HYPOTHESIS Pitchers who required UCLR have thrown a greater percentage of fastballs and have greater pitch(More)
W ith the increasing popularity of competitive cycling in America, it is reasonable to assume that crash-related injuries will continue to increase. 4 For professional riders the major risk factors for such injuries include both extensive time on the bike and roadways in addition to a possible underlying osteopenia secondary to the nonimpact nature of the(More)
Anterior shoulder surgery, using open or arthroscopic technique, places subcoracoid neurovasculature at risk. This study examines the relationships of the brachial plexus and axillary artery to four bony landmarks and provides clinical correlations for anterior shoulder surgery. The musculocutaneous nerve (MN), posterior cord (PC), lateral cord (LC), and(More)
We sought to report a central T2 hypointensity within the optic nerve on 3 T MRI studies obtained as part of the NASA Flight Medicine Visual Impairment Intracranial Pressure Protocol that had not been described previously. Twenty-one astronauts, who had undergone MRI of both orbits with direct coronal T2 sequences between 2010 and 2012, were retrospectively(More)
