Ultrashort echo time MRI detects significantly lower collagen but higher pore water in the tibial cortex of female patients with osteopenia and osteoporosis.

Ultrashort echo time (UTE) MRI can quantify the major proton pool densities in cortical bone, including total (TWPD), bound (BWPD), and pore water (PWPD) proton densities, as well as the macromolecular proton density (MMPD), associated with the collagen content, which is calculated using macromolecular fraction (MMF) from UTE magnetization transfer (UTE-MT) modeling. This study aimed to investigate the differences in water and collagen contents in tibial cortical bone, between female osteopenia (OPe) patients, osteoporosis (OPo) patients, and young participants (Young). Being postmenopausal and above 55 yr old were the inclusion criteria for OPe and OPo groups.

Yoga Plus Mantram Repetition to Reduce Chronic Pain in Veterans With Post-Traumatic Stress Disorder: A Feasibility Trial.

Background: Veterans with post-traumatic stress disorder (PTSD) are more likely to report chronic pain than veterans without PTSD. Yoga has been shown to reduce both chronic pain and PTSD symptoms in clinical trials. The goal of our study was to assess the feasibility and acceptability of conducting a randomized controlled trial (RCT) that combined yoga and mantram repetition (Yoga + MR) into one program for military veterans with both chronic pain and PTSD.

Comparing Types of Yoga for Chronic Low Back and Neck Pain in Military Personnel: A Feasibility Randomized Controlled Trial.

Background: Chronic low back pain (cLBP) and chronic neck pain (cNP) are highly prevalent conditions and common reasons for disability among military personnel. Yoga and other mind-body interventions have been shown to safely decrease pain and disability in persons with cLBP and/or cNP but have not been adequately studied in active duty military personnel. The objective of this study was to examine the feasibility and acceptability of delivering 2 types of yoga (hatha and restorative) to a sample of active-duty military personnel with cLBP/cNP.

Lower Macromolecular Content in Tendons of Female Patients with Osteoporosis versus Patients with Osteopenia Detected by Ultrashort Echo Time (UTE) MRI.

Tendons and bones comprise a special interacting unit where mechanical, biochemical, and metabolic interplays are continuously in effect. Bone loss in osteoporosis (OPo) and its earlier stage disease, osteopenia (OPe), may be coupled with a reduction in tendon quality. Noninvasive means for quantitatively evaluating tendon quality during disease progression may be critically important for the improvement of characterization and treatment optimization in patients with bone mineral density disorders.

An Update in Qualitative Imaging of Bone Using Ultrashort Echo Time Magnetic Resonance.

Bone is comprised of mineral, collagenous organic matrix, and water. X-ray-based techniques are the standard approach for bone evaluation in clinics, but they are unable to detect the organic matrix and water components in bone. Magnetic resonance imaging (MRI) is being used increasingly for bone evaluation.

Intraligamentous synovial chondromatosis of the anterior cruciate ligament.

Synovial chondromatosis is a rare disease that causes disability and dysfunction of the involved synovial joint. We describe the second case in the literature of intraligamentous synovial chondromatosis involving the anterior cruciate ligament, confirmed by pathology after arthroscopic removal of the chondral bodies. We also describe associated magnetic resonance imaging findings which may be helpful for diagnosis of this very rare entity.

Secondary Outcomes from a Randomized Controlled Trial of Yoga for Veterans with Chronic Low-Back Pain.

Chronic low-back pain (cLBP) is a prevalent condition, and rates are higher among military veterans. cLBP is a persistent condition, and treatment options have either modest effects or a significant risk of side-effects, which has led to recent efforts to explore mind-body intervention options and reduce opioid medication use. Prior studies of yoga for cLBP in community samples, and the main results of a recent trial with military veterans, indicate that yoga can reduce back-related disability and pain intensity.

Brain Amygdala Volume Increases in Veterans and Active-Duty Military Personnel With Combat-Related Posttraumatic Stress Disorder and Mild Traumatic Brain Injury.

Objective: To identify amygdalar volumetric differences associated with posttraumatic stress disorder (PTSD) in individuals with comorbid mild traumatic brain injury (mTBI) compared with those with mTBI-only and to examine the effects of intracranial volume (ICV) on amygdala volumetric measures.

Setting: Marine Corps Base and VA Healthcare System.

Participants: A cohort of veterans and active-duty military personnel with combat-related mTBI (N = 89).

Nonoperative Management of a Severe Proximal Rectus Femoris Musculotendinous Injury in a Recreational Athlete: A Case Report.

Integrated Exposure Therapy and Exercise Reduces Fear of Falling and Avoidance in Older Adults: A Randomized Pilot Study.

Objectives: To evaluate the safety and acceptability of a novel 8-week intervention integrating exercise, exposure therapy, cognitive restructuring, and a home safety evaluation, conducted by a physical therapist, in reducing fear of falling and activity avoidance. To collect preliminary evidence of efficacy.

Design: Randomized pilot study comparing the intervention to time- and attention-equivalent fall prevention education.

From the international space station to the clinic: how prolonged unloading may disrupt lumbar spine stability.

Background Context: Prolonged microgravity exposure is associated with localized low back pain and an elevated risk of post-flight disc herniation. Although the mechanisms by which microgravity impairs the spine are unclear, they should be foundational for developing in-flight countermeasures for maintaining astronaut spine health. Because human spine anatomy has adapted to upright posture on Earth, observations of how spaceflight affects the spine should also provide new and potentially important information on spine biomechanics that benefit the general population.

Yoga for Military Veterans with Chronic Low Back Pain: A Randomized Clinical Trial.

Introduction: Chronic low back pain (cLBP) is prevalent, especially among military veterans. Many cLBP treatment options have limited benefits and are accompanied by side effects. Major efforts to reduce opioid use and embrace nonpharmacological pain treatments have resulted.

Lumbar Spine Paraspinal Muscle and Intervertebral Disc Height Changes in Astronauts After Long-Duration Spaceflight on the International Space Station.

Study Design: Prospective case series.

Objective: Evaluate lumbar paraspinal muscle (PSM) cross-sectional area and intervertebral disc (IVD) height changes induced by a 6-month space mission on the International Space Station. The long-term objective of this project is to promote spine health and prevent spinal injury during space missions and here on Earth.

Yoga as a treatment for chronic low back pain: A systematic review of the literature.

Objectives: Chronic low back pain (CLBP) affects millions of people worldwide, and appears to be increasing in prevalence. It is associated not only with pain, but also with increased disability, psychological symptoms, and reduced quality of life. There are various treatment options for CLBP, but no single therapy stands out as being the most effective.

Yoga for veterans with chronic low back pain: Design and methods of a randomized clinical trial.

Chronic low back pain (CLBP) afflicts millions of people worldwide, with particularly high prevalence in military veterans. Many treatment options exist for CLBP, but most have limited effectiveness and some have significant side effects. In general populations with CLBP, yoga has been shown to improve health outcomes with few side effects.

WISE 2005: Aerobic and resistive countermeasures prevent paraspinal muscle deconditioning during 60-day bed rest in women.

Microgravity-induced lumbar paraspinal muscle deconditioning may contribute to back pain commonly experienced by astronauts and may increase the risk of postflight injury. We hypothesized that a combined resistive and aerobic exercise countermeasure protocol that included spinal loading would mitigate lumbar paraspinal muscle deconditioning during 60 days of bed rest in women. Sixteen women underwent 60-day, 6° head-down-tilt bed rest (BR) and were randomized into control and exercise groups.

Anatomic Evaluation of the Sacroiliac Joint: A Radiographic Study with Implications for Procedures.

Background: Sacroiliac joint (SI) pain is increasingly being recognized as a source of low back pain. Injections and percutaneous type procedures are performed to treat symptomatic joints. However, there are limited studies available assessing the anatomy of the SI joint in vivo among patients with pain.

Return to Learn: A review of cognitive rest versus rehabilitation after sports concussion.

Background: Cognitive rest is the recommendation for all patients with acute sports concussion.

Objective/methods: A comprehensive literature search was conducted for the research question "What is the optimal cognitive load for patients with a sports concussion?"

Results: Seven studies met the inclusion criteria. The optimal cognitive load for patients after sports concussion is yet to be determined.

Single-subject-based whole-brain MEG slow-wave imaging approach for detecting abnormality in patients with mild traumatic brain injury.

Traumatic brain injury (TBI) is a leading cause of sustained impairment in military and civilian populations. However, mild TBI (mTBI) can be difficult to detect using conventional MRI or CT. Injured brain tissues in mTBI patients generate abnormal slow-waves (1-4 Hz) that can be measured and localized by resting-state magnetoencephalography (MEG).

Body posture and backpack loading: an upright magnetic resonance imaging study of the adult lumbar spine.

Purpose: Axial loading of the spine while supine, simulating upright posture, decreases intervertebral disc (IVD) height and lumbar length and increases lumbar lordosis. The purpose of this study is to measure the adult lumbar spine's response to upright posture and a backpack load using upright magnetic resonance imaging (MRI). We hypothesize that higher spinal loads, while upright and with a backpack, will compress lumbar length and IVD height as well as decrease lumbar lordosis.
