Skeletal muscle atrophy, increased adiposity and reduced physical activity are key changes observed after spinal cord injury (SCI) and are associated with numerous cardiometabolic health consequences. These changes are likely to increase the risk of developing chronic secondary conditions and impact the quality of life in persons with SCI. Surface neuromuscular electrical stimulation evoked resistance training (NMES-RT) was developed as a strategy to attenuate the process of skeletal muscle atrophy, decrease ectopic adiposity, improve insulin sensitivity and enhance mitochondrial capacity...

Motor control and body representation in the central nervous system (CNS) as well as musculoskeletal architecture and physiology are shaped during development by sensorimotor experience and feedback, but the emergence of locomotor disorders during maturation and their persistence over time remain a matter of debate in the absence of brain damage. By using transient immobilization of the hind limbs, we investigated the enduring impact of postnatal sensorimotor restriction (SMR) on gait and posture on treadmill, age-related changes in locomotion, musculoskeletal histopathology and Hoffmann reflex in adult rats without brain damage...

BACKGROUND: Neuromuscular electrical stimulation (NMES) is commonly used in skeletal muscles in people with spinal cord injury (SCI) with the aim of increasing muscle recruitment and thus muscle force production. NMES has been conventionally used in clinical practice as functional electrical stimulation (FES), using low levels of evoked force that cannot optimally stimulate muscular strength and mass improvements, and thus trigger musculoskeletal changes in paralysed muscles. The use of high intensity intermittent NMES training using wide-pulse width and moderate-intensity as a strength training tool could be a promising method to increase muscle force production in people with SCI...

Estimation of muscle forces through musculoskeletal simulation is important in understanding human movement and injury. Unmatched filter frequencies used to low-pass filter marker and force platform data can create artifacts during inverse dynamics analysis, but their effects on muscle force calculations are unknown. The objective of this study was to determine the effects of filter cutoff frequency on simulation parameters and magnitudes of lower extremity muscle and resultant joint contact forces during a high-impact maneuver...

OBJECTIVE: To evaluate the significance of biceps tendon (BT) displacement and peri-bicipital hematoma on MRI in subjects with pectoralis major (PM) tears. We hypothesized that these features might be associated with tear severity at surgery. MATERIALS AND METHODS: We retrospectively identified MRI cases with PM injury and reviewed clinical, imaging, and surgical records. MR images were reviewed independently by two musculoskeletal radiologists to determine anterior displacement of BT (BT-disp, in mm) and the presence of triangular-shaped peri-bicipital hematoma...

Introduction: In November 2014, the U.S. Army held a readiness summit to address concerns about the accuracy of medical reporting systems. At the time, soldiers on temporary disability were tracked as a medical readiness classification (MRC) 3A or 3B. MRC 3A soldiers had a medical condition with recovery expected within 30 d and MRC 3B soldiers were expected to take longer than 30 d to recover. Both groups were considered "non-available" and presumably non-deployable. Starting June 1, 2016, with the implementation of the Army Medical Readiness Transformation, soldiers on temporary disability longer than 14 d began to be reported as MRC 3s and are considered "non-deployable...

Various therapies for the treatment of sprains have emerged as advances occur in biomedical engineering and photobiology. Therapy with coherent and non-coherent light is a treatment modality for various musculoskeletal injuries. The main certified phototherapy benefits are the reduction of nociceptive processes and the modulation of the inflammatory process, among others. The objective of this study was to analyse the changes caused by the use of light-emitting diodes (LED) (λ627 ± 10 nm) with an energy density of 10 J/cm2 in 40 subjects divided into two groups (20 placebo and 20 LED)...

Anterior cruciate ligament (ACL) injuries are a burdensome condition due to potential surgical requirements and increased risk of long term debilitation. Previous studies indicate that muscle forces play an important role in the development of ligamentous loading, yet these studies have typically used cadaveric models considering only the knee-spanning quadriceps, hamstrings and gastrocnemius muscle groups. Using a musculoskeletal modelling approach, we investigated how lower-limb muscles produce and oppose key tibiofemoral reaction forces and moments during the weight acceptance phase of unanticipated sidestep cutting...

The majority of musculoskeletal injuries located in the shoulder are often due to repetitive or sustained movements that occur in work routines in different areas. In the case of musicians, such as violinists, who have long and daily training routines, the repetitive movements they perform are forced and sometimes the postures are not natural. Therefore, this article aims to study and simulate the dynamic behavior of the glenohumeral joint under repetitive conditions that represent the different postures assumed by a violinist during his daily training...

Spinal cord injury (SCI) causes impaired neuronal function with associated deficits in the musculoskeletal system, which can lead to permanent disability. Here, the impact of SCI on in vivo musculoskeletal adaptation was determined by studying deficits in locomotor function and analyzing changes that occur in the muscle and bone compartments within the rat hind-limb following contusion or transection SCI. Analyses of locomotor patterns, as assessed via the Basso, Beattie, and Bresnahan (BBB) rating scale, revealed that transection animals showed significant deficits, while the contusion group had moderate deficits, as compared to naïve groups...

INTRODUCTION: Women account for approximately 15% of the active duty US Army, and studies show that women may be at an increased risk of musculoskeletal injury during sport and military training. Nationally, the field of orthopedic surgery comprises 14% women, lagging behind other surgical fields. Demographics for US Military orthopedic surgeons are not readily available. Similarly, demographic data of graduating medical students entering Military Medicine are not reported. We hypothesize that a gender disparity within military orthopedics will be apparent...

BACKGROUND: Musculoskeletal conditions are among the most common and costly conditions suffered by Americans. In 2011, there was an estimated $213 billion in annual cost of direct treatment for and lost wages due to musculoskeletal disease in the United States. Data on economic burden, however, comes mostly from the adult population, with significantly less information regarding the burden of these conditions in young patients available. The purpose of this report is to provide data on the economic burden of musculoskeletal diseases in children and adolescents in the United States...
