In January 2013, the Department of Defense lifted a ban that had prevented women from holding combat positions in military. However, innate differences physical traits and physiology between men likely will result performance. Sex thermoregulation is key area needs to be examined due potential impact on Therefore, we expanded our previously developed model (TRM) include effects gender. Women have been found lower sweat output heat stress lesser shivering cold than men; therefore, equations...

Wide-awake local anesthesia with no tourniquet has dramatically changed hand surgery practice. Using lidocaine epinephrine and allowed many procedures to be moved from the main operating room an in-office procedure room. Previous studies have shown that using is safe cost effective, high patient satisfaction. This study evaluated satisfaction complications for first 1,011 elective surgeries performed wide-awake in room.The patients who underwent were surveyed regarding their The monitored...

This article presents a model-based method for predicting primary blast injury. On the basis of normalized work injury mechanism from previous work, this new model that accounts effects orientation and species difference.The analysis used test data series extensive experimental studies sponsored by US Army Medical Research Materiel Command. In these studies, more than 1200 sheep were exposed to air in free-field confined enclosures, lung injuries quantified as percentage surface area...

There is a lack of valid and reliable tests that assess upper extremity strength function for rehabilitation injury prevention purposes in throwing athletes. The Athletic Shoulder (ASH) test has been proposed as measure shoulder strength, but not yet studied baseball pitchers.

Physical performance emerges from complex interactions among many physiological systems that are largely driven by the metabolic energy demanded. Quantifying demand is an essential step for revealing mechanisms of physical decrement, but accurate predictive models do not exist. The goal this study was to investigate if a recently developed model muscle energetics and force could be extended reproduce kinematics, kinetics, submaximal effort movement. Upright dynamic knee extension against...

Functional electrical stimulation (FES) has the capacity to regenerate motion for individuals with spinal cord injuries. However, it is not straightforward determine parameters generate a coordinated movement. Musculoskeletal models can provide noninvasive simulation environment estimate muscle force and activation timing sequences variety of tasks. Therefore, purpose this study was develop musculoskeletal model feline hindlimb simulations intrafascicular multielectrode (a method FES)....

Aim: 3D printing is a growing technology with promising applications in orthopedic surgery. However, the utilization of 3D-printed surgical implants has not been fully explored. Materials & methods: One-third tubular plates and cortical screws were printed via fused deposition modeling using four materials: acrylonitrile butadiene styrene, carbon fiber-reinforced polylactic acid, polycarbonate polyether ether ketone. Plates analyzed three-point bending torque testing, underwent torque, shear...

Low scores on psychological patient-reported outcomes measures, including the Anterior Cruciate Ligament-Return to Sport After Injury (ACL-RSI) and Injury-Psychological Readiness Return (I-PRRS), after anterior cruciate ligament reconstruction (ACLR) have been associated with a maladaptive response injury poor prognosis.

Introduction: External fixation is a critical component of orthopaedic fracture management and used for various conditions, including trauma pediatric orthopaedics. However, the availability high cost external devices are concern, especially in rural developing countries. 3D printing technology has shown promise reducing manufacturing costs improving accessibility to devices. The purpose this study was evaluate mechanical properties fully 3D-printed desktop device compare results with...

The goal of acetabular labral repair is to restore stable contact between the labrum and rim while maintaining anatomic suction seal. One challenges achieving proper in-round repair, so that contacts femoral head in native position. This technique article presents a method allows for enhanced inversion assist with repair. Our modified toggle suture utilizes an anchor-first has various distinct technical advantages. We present efficient vendor-agnostic straight or curved guides. Similarly,...

ABSTRACT Introduction Proper jump-landing neuromuscular control is crucial in mitigating lower-extremity musculoskeletal injuries. The presence of fatigue, especially extreme environments, may degrade dynamic postural stability (DPS) and result This study aimed to evaluate the influence moderate intensity exercise hot (HOT) temperate (TEMP) ambient temperatures residual effects a previous bout on DPS during single-legged jump-landing. It was hypothesized that participants would display worse...

Baseball pitching is a well-studied area of sports biomechanics partially due to high upper extremity (UE) injury rates. Joint kinetics have not been linked directly UE in pitchers but are often used lieu data as proxy for risk. Pitchers exhibit adaptations the throwing arm that may affect body segment inertial parameters (BSIPs); however, these unaccounted traditional modelling methods and contribute lack evidence linking joint injury. Therefore, this study aimed describe BSIPs adolescent...

Objectives: The anterolateral ligament (ALL) is an important structure for knee stability and has roles in maintaining internal rotation anterior-posterior anterior cruciate (ACL)- insufficient knees. There a growing body of evidence demonstrating superior clinical outcomes including reduced graft failure rate residual pivot shift with combined ACL ALL reconstruction compared to isolated reconstruction. One common complication this procedure convergence the two tunnels used passage. Several...

Biomechanical deficits during jump landings often contribute to common lower extremity musculoskeletal (MSK) injuries in athletes. Time stabilization (TTS) measurements have recently been used assess MSK injury risk. Greater TTS values represent a diminished dynamic postural stability. PURPOSE: To determine the reliability of single-legged jump-landing task. We hypothesized that would be good for both within- and between-day measures. METHODS: Eight physically active male participants (16.8...
