Daily Naltrexone Use Does Not Adversely Affect Physical, Cognitive or Marksmanship Performance in U.S. Army Soldiers.

Introduction: Considering the potential of weaponized opioids, evaluating how prophylactic countermeasures affect military-relevant performance is necessary. Naltrexone is a commercially available Food and Drug Administration-approved medication that blocks the effects of opioids with minimal side effects. However, the effects of naltrexone on the health and performance of non-substance abusing military personnel are not well described in the existing literature.

Short-term neurochemical effects of transcutaneous trigeminal nerve stimulation using 7T magnetic resonance spectroscopy.

Background And Purpose: The purpose was to explore the effects of transcutaneous trigeminal nerve stimulation (TNS) on neurochemical concentrations (brainstem, anterior cingulate cortex [ACC], dorsolateral prefrontal cortex [DLPFC], ventromedial prefrontal cortex [VMPFC], and the posterior cingulate cortex [PCC]) using ultrahigh-field magnetic resonance spectroscopy.

Methods: This double-blinded study tested 32 healthy males (age: 25.4 ± 7.

The Association Between Sleep and Musculoskeletal Injuries in Military Personnel: A Systematic Review.

Introduction: Musculoskeletal injuries (MSKIs) are a significant health problem in the military. Accordingly, identifying risk factors associated with MSKI to develop targeted strategies that attenuate injury risk remains a top priority within the military. Insufficient sleep has garnered increased attention as a potential risk factor for MSKI in both civilians and military personnel.

Association Between Self-Reported Sleep Quality and Musculoskeletal Injury in Male Army Rangers.

Introduction: Musculoskeletal injuries and insufficient sleep are common among U.S. Army Rangers.

Physical sleeping environment is related to insomnia risk and measures of readiness in US army special operations soldiers.

Background: US military service members have characteristically poor sleep, even when '' or at one's home base. The physical sleeping environment, which is often poor in military-provided housing or barracks, may contribute to poor sleep quality in soldiers. The current study aimed to assess whether the sleeping environment in garrison is related to sleep quality, insomnia risk and military readiness.

The Occupational Military Neuromusculoskeletal Injury Matrix.

Introduction: Neuromusculoskeletal injuries (NMSKIs) are the primary cause of ambulatory visits, lost duty days, and disability discharges in the U.S. Military.

Transitioning from daytime to nighttime operations in military training has a temporary negative impact on dynamic balance and jump performance in U.S. Army Rangers.

Objectives: Explore the impact transitioning from daytime to nighttime operations has on performance in U.S. Army Rangers.

Sleep and occupational well-being in active duty special operations soldiers: A replication and expansion.

Objective: To assess the relationship between sleep quality and occupational well-being in active duty military Service Members.

Design: Longitudinal prospective analysis.

Setting: An annual military training event.

Sleep health of incoming army trainees and how it changes during basic combat training.

Objective: To examine the sleep health of incoming Army trainees and how it is impacted during basic combat training (BCT).

Design: Prospective.

Setting: BCT site (Fort Jackson, SC).

Geographically based risk assessment of sleep disorders and disease states impacting medical readiness across active duty army installations from military medical databases in fiscal year 2017.

Background: The impact of sleep disorders on active duty Soldiers' medical readiness is clinically significant. Sleep disorders often present high comorbidity with disease states impacting readiness ranging from obesity and drug dependence. Patient data generated from military health databases can be accessed to examine such relationships.

Effect of Self-Controlled Practice on Neuro-Cortical Dynamics During the Processing of Visual Performance Feedback.

Evidence has accumulated that learners participating in self-controlled practice can both acquire skills and process task-relevant information more effectively than those participating in externally controlled practice. However, the impact of self-controlled practice on neuro-cognitive information processing during visual performance-related feedback has received limited investigation. We expected that individuals participating in self-controlled practice would exhibit elevated neuro-cognitive information processing, as assessed via electroencephalography (EEG), compared with those engaged with externally controlled practice.

Sleep loss is related to unstable stationary balance in U.S. Army soldiers in an operationally-relevant context.

Background: Sleep loss negatively impacts stationary balance in a laboratory setting, but few studies have examined this link in a naturalistic environment. We tested this relationship in U.S.

Sleep health and its association with performance and motivation in tactical athletes enrolled in the Reserve Officers' Training Corps.

Objective: To examine habitual sleep health and investigate how habitual sleep duration impacts performance and motivation in Reserve Officers' Training Corps (ROTC) tactical athletes.

Design: Observational.

Setting: A large, state university.

Effects of sleep extension on cognitive/motor performance and motivation in military tactical athletes.

Objective: Investigate the immediate and residual impacts of sleep extension in tactical athletes.

Methods: A randomized controlled trial (Sleep extension = EXT vs Control = CON) was conducted on 50 (EXT: 20.12 ± 2.

A description of injuries in men and women while serving in Afghanistan.

Musculoskeletal injuries (MSIs) are the most common cause of ambulatory visits in the deployed setting. Research done on deployed populations have focused mostly on men. The purpose of this retrospective cohort study was to describe physical demands and MSIs among male and female soldiers in a Brigade Combat Team during a 12-month deployment to Afghanistan.

Risk factors for musculoskeletal injuries for soldiers deployed to Afghanistan.

Purpose: This study determined injury incidence and examined the association between musculoskeletal injuries and potential intrinsic and extrinsic risk factors.

Methods: This retrospective cohort study involved a survey of 593 volunteers from two battalions of a Stryker Brigade Combat Team upon completion of a 12-mo deployment to Afghanistan. The survey included questions on physical characteristics, work duties, equipment worn, fitness training, and injuries experienced during the deployment.

Lifting tasks are associated with injuries during the early portion of a deployment to Afghanistan.

The short-term effects of thoracic spine thrust manipulation on patients with shoulder impingement syndrome.

The study was an exploratory, one group pretest/post-test study, with the objective of investigating the short-term effects of thoracic spine thrust manipulations (TSTMs) on patients with shoulder impingement syndrome (SIS). There is evidence that manual physical therapy that includes TSTM and non-thrust manipulation and exercise is effective for the treatment of patients with SIS. However, the relative contributions of specific manual therapy interventions are not known.
