BACKGROUND: Extreme conditioning programs (ECPs) are fitness training regimens relying on aerobic, plyometric, and resistance training exercises, often with high levels of intensity for a short duration of time. These programs have grown rapidly in popularity in recent years, but science describing the safety profile of these programs is lacking. HYPOTHESIS: The rate of injury in the extreme conditioning program is greater than the injury rate of weightlifting and the majority of injuries occur to the shoulder and back...

Lipedema, or adiposis dolorosa, is a common adipose tissue disorder that is believed to affect nearly 11% of adult women worldwide. It is characterized most commonly by disproportionate adipocyte hypertrophy of the lower extremities, significant tenderness to palpation, and a failure to respond to extreme weight loss modalities. Women with lipedema report a rapid growth of the lipedema subcutaneous adipose tissue in the setting of stress, surgery, and/or hormonal changes. Women with later stages of lipedema have a classic "column leg" appearance, with masses of nodular fat, easy bruising, and pain...

PURPOSE: Insomnia is problematic for older adults. After behavioral modifications fail to show adequate response, pharmacologic options are used. The pharmacokinetics of agents used to treat insomnia may be altered. This review focuses on the safety and efficacy of medications used to treat insomnia. METHODS: A literature search of Medline, PubMed, and Embase was conducted (January 1966-June 2016). It included systematic reviews, randomized controlled trials, observational studies, and case series that had an emphasis on insomnia in an older population...

Previous studies have shown conflicting information regarding leg dominance as an etiological factor for the risk of anterior cruciate ligament (ACL) injuries. It remains unclear if lower extremity neuromechanical limb asymmetries exist in experienced athletes. The purpose of this study was to evaluate lower extremity neuromechanical effects of leg dominance in female collegiate soccer athletes during an unanticipated side-step cutting task. Twenty female collegiate soccer players completed an unanticipated side-step cutting task, using their dominant and non-dominant legs...

BACKGROUND: The number of knee arthroplasties performed each year is steadily increasing. Although the outcome is generally favourable, up to 15 % fail to achieve a satisfactory clinical outcome which may indicate that the existing model of rehabilitation after surgery may not be the most efficacious. Given the increasing number of knee arthroplasties, the relative limited physiotherapy resources available and the increasing age and frailty of patients receiving arthroplasty surgery, it is important that we concentrate our rehabilitation resources on those patients who most need help to achieve a good outcome...

The aim of this study was to evaluate the effect of a continuous locomotor training on leg muscle EMG exhaustion during assisted stepping movements in a patient with motor complete spinal cord injury (SCI). EMG exhaustion and loss of potentials starts to develop in non-trained patients usually around six months after injury. In the trained patient examined in this study exhaustion was also observed but occurred with a delay of several months. In contrast to a non-trained patient no more EMG exhaustion was observed in a very chronic stage...

BACKGROUND: Acute lower extremity compartment syndrome (CS) is a condition that untreated causes irreversible nerve and muscle ischemia. Treatment by decompression fasciotomy without delay prevents permanent disability. The use of intracompartmental pressure (iCP) measurement in uncertain situations aids in diagnosis of severe leg pain. As an infrequent complication of lower extremity trauma, consequences of CS include chronic pain, nerve injury, and contractures. The purpose of this study was to observe the clinical and functional outcomes for patients with lower extremity CS after fasciotomy...

INTRODUCTION: The true incidence of venous thromboembolism (VTE) in patients with acute spinal cord injury (SCI) is unclear. There are limited data on the risk factors associated with VTE in patients with an acute SCI. METHODS: We performed a retrospective chart review of consecutive adult patients with acute SCI. The primary outcome was incidence of symptomatic deep vein thrombosis (DVT) or pulmonary embolism (PE) within 90days. Secondary outcomes were major bleeding, all-cause mortality, and fatal PE...

BACKGROUND: This study evaluates sports ability, rotational laxity and potential growth changes in children after transphyseal ACL reconstruction with metaphyseal fixation technique, considering physis biology by placing drill holes vertically in the femoral anatomic origin in order to reduce volumetric injury to the physis. METHODS: In this retrospective trial of 42 patients data were collected. Thirty-seven were reviewed measuring rotational laxity and anteroposterior tibial translation using the Laxitester (ORTEMA Sport Protection, Markgroeningen, Germany) and the KT1000...

BACKGROUND: Understanding the whole-body patterns of joint flexibility and their related biological and physical factors contributes not only to clinical assessments but also to the fields of human factors and ergonomics. In this study, ranges of motion (ROMs) at limb and trunk joints of young adults were analysed to understand covariation patterns of different joint motions and to identify factors associated with the variation in ROM. METHODS: Seventy-eight healthy volunteers (42 males and 36 females) living on Okinawa Island, Japan, were recruited...

The efficacy of injury prevention exercise programs (IPEPs) for amateur youth soccer has been established, but little is known about their adaptability to other soccer populations. This study aimed to assess the use of individual injury prevention exercises by professional youth soccer teams, against the industry-standard, FIFA 11+ program. Four teams' chosen IPEPs were observed across one season and documented on a standardized form. The use of each FIFA 11+ exercise was coded as "performed", "performed modified" or "not performed"...

An entrapment of the femoral artery by cerclage wiring is a rare complication after spiral diaphyseal femoral fractures. We report the case of an 82-year-old female treated by an antegrade intramedullary nailing and multiple cable augmentation, which was then complicated by injury to the femoral artery that resulted in ipsilateral leg necrosis and amputation. The entrapment was caused by direct belting by the cable and resulted in a total obstruction of the femoral artery.

STUDY DESIGN: Crossover design. CONTEXT: Excessive valgus and varus force which affected the knee joint during dynamic tasks has been often associated to lower extremity injuries. Strategies to increase the resistance against these asymmetries, such as, the use of a physioball between the knees or elastic bands around the knees are often applied in rehabilitation and conditioning programs. OBJECTIVE: The purpose of this study was to investigate the effect of performing leg press (LP) 45° using a physioball and elastic band over multiple sets with submaximal loads on electromyographic (EMG) amplitude and fatigue indices...

BACKGROUND: It is unclear whether isolated gastroc/soleus tightness can increase the risk of lower extremity injury in an otherwise healthy child. QUESTIONS/PURPOSES: (1) Is there a difference in gastroc/soleus tightness, as represented by ankle dorsiflexion with the knee extended, in children presenting with upper versus lower extremity complaints? (2) Is there a difference in gastroc/soleus tightness in children presenting with atraumatic versus traumatic lower extremity complaints? METHODS: We performed a cross-sectional study of 206 consecutive walking age children presenting to a county orthopedic clinic with new upper or lower extremity complaints...

The aim of this study was to determine the effect of aging on power generation and joint coordination during a leg press, in order to increase understanding of how functional movements are affected during the aging process. 44 older and 24 younger adults performed eight sub-maximal power repetitions on a seated leg press dynamometer. Peak power and velocity (at 40% maximum resistance) were measured along with the coordination (coupling angle) of the lower limb joints using the vector coding technique. The younger adults produced significantly greater peak power than the older adults (mean ± SD; 762 W ± 245 vs 361 W ± 162, p < 0...

The foot-ankle complex is frequently injured in a wide array of debilitating events such as car crashes. Numerical models and experimental tests have been used to assess injury risk, but most do not account for the variations in ankle posture that frequently occur during these events. In this study, the positions of the bones of the foot-ankle complex (particularly, the hindfoot) were quantified over a range of postures. Computed tomography scans were taken of a male cadaveric leg under axial loading with the ankle in five postures in which fractures are commonly reported...
