“…It is hoped that device modifications can be made or more constrained tests can be devised that tap into smaller and more subtle dynamic aspects of movement control during EST use. Also, other non-EST approaches should be explored that may prove more portable and face fewer limitations when analysis of highly dynamic behavior is needed (Lawson, Rupert, & Cho, 2013;Lawson, Rupert, & Legan, 2012). Finally, it would be interesting to study elite shooters and also shooters in training.…”

Software innovations at our laboratory have made novel measures of shooting performance available to researchers, even when the data comes from a fielded military firearms training simulator not designed for research. This study analyzed specific patterns of rifle handling and control to determine how they affected reaction time and accuracy among shooters of differing skill levels. The results indicated the skilled shooters employed smoother and more efficient rifle movement while aiming than less-skilled shooters. While shooters know that trigger control and sight picture are important, this study confirms that skilled shooting is also influenced by the efficiency of the rifle movements that immediately precede the shot.

“…The role of vision in balance rehabilitation can change depending on the postural task, balance deficits, stage of recovery, and the environment. For example, vestibular-ocular (VO) deficits often accompany blast related balance dysfunction and in these cases the vision system requires compensation and habituation during rehabilitation [19,20].…”

This paper describes development of an activity based, multimodal balance rehabilitation training device. Various sensors can be used, including a force plate, inertial sensors, and depth sensing cameras, and various combinations of visual, auditory and tactile feedback can be configured depending on the rehabilitation task and activity. Tactile feedback is presented via a lightweight belt that is worn on the torso. Generally, visual feedback is only needed at the start of rehabilitation training (task orientation) while tactile feedback may be used to augment balance control. Tactile feedback can be configured as a cue that certain movement targets or limits have been reached or as an immediate indicator of the variance in postural sway. Tactile feedback allows the subject to naturally concentrate on the functional rehabilitation task, and is less reliant on visual or verbal cues.

“…The sensory cells in the vestibule sense the movements of the head and they send the impulses to the brain through the vestibulocochlear nerve. Vestibular injury can lead to balance problems [287][288][289][290]. After prolonged systemic exposure, aminoglycosides accumulate in the outer and eventually the inner hair cells that are present at the base of the cochlea.…”

A Single, Ultra‐High Dose Aminoglycoside Therapy in a Rat Model of E. coli Induced Septic Shock

Bacterial infections are a major cause of morbidity and mortality in both the community and nosocomial settings, particularly among the elderly and chronically ill. Sepsis is the body's response to antigens and toxins released by the invasive pathogenic organisms that cause infection. When infection is not effectively controlled, sepsis may develop and progress to severe sepsis and septic shock. Early diagnosis and treatment is pivotal for survival in severe sepsis and particularly, septic shock. Our research focuses on developing a novel treatment strategy for septic shock by using single, ultra-high doses of aminoglycosides.In this project, the effect of a single, ultra-high dose of gentamicin in clearing bacteria from the blood and reducing the bacterial burden in vital organs was evaluated in a rat model of E. coli (Bort strain) induced peritonitis with severe sepsis/septic shock. Serum cytokine levels and serum lactate levels were serially measured. Further, the potential adverse effects of ultra-high dosing of aminoglycoside antibiotics in a short-term (9 h) invasive study and longterm (180 days) non-invasive study were assessed. Neuromuscular paralyses due to ultra-high doses of aminoglycosides were assessed. In addition, renal injury markers such as serum creatinine and urinary Neutrophil Gelatinase Associated Lipocalin (NGAL) were assayed.The auditory and vestibular function was also assessed after ultra-high dosing of aminoglycoside in the long-term study.We conclude that animals can tolerate ultra-high doses of aminoglycosides with appropriate support. Animals were under neuromuscular paralysis for 28 -50 minutes and were on ventilator support after single ultra-high doses (80 and 160 mg/kg) of aminoglycoside antibiotics (gentamicin and tobramycin). There was no significant acute or delayed renal or ototoxicity associated with the single, ultra-high dose aminoglycoside therapy. Histology gratitude to my committee members Dr. Michelle Alfa, Dr. George Zhanel, Dr. Rob Ariano and Dr. Sheryl Zelenitsky for their continual support, feedback, encouragement and for their insightful comments. Special thanks to Dr. Phillip Gardiner for his support in performing pilot studies. I am thankful to Dr. Brian Blakley for his support for performing auditory brain stem response studies. I am also grateful to Dr.
