Intramuscular hematoma in rhabdomyolysis patients treated with low-molecular-weight heparin: Report of two cases.

World J Clin Cases 2021 Apr;9(12):2838-2844

Department of Critical Care Medicine, Nanping First Hospital Affiliated to Fujian Medical University, Nanping 353000, Fujian Province, China.

Deep neuromuscular paralysis during hip arthroscopic surgery: influence on perineal tissue pressures and hip joint width.

J Hip Preserv Surg 2020 Aug 2;7(3):533-536. Epub 2020 Dec 2.

Department of Anaesthesia, Joondalup Health Campus, Cnr Lakeside Drive & Shenton Avenue, Joondalup, WA 6027, Australia.

Pudendal nerve injuries are not an uncommon side effect of patient positioning on a traction table, and muscle relaxation has been suggested to mitigate this risk by reducing pressure on the perineum. A total of 40 patients scheduled for hip arthroscopic surgery under general anaesthesia were recruited. After induction of anaesthesia, pressures on the perineum were measured in 20 subjects by means of an ultra-thin pressure sensor mat wrapped around the perineal post. Read More

Auxiliary Diagnostic Method for Patellofemoral Pain Syndrome Based on One-Dimensional Convolutional Neural Network.

Front Public Health 2021 16;9:615597. Epub 2021 Apr 16.

College of Physics and Information Engineering, Fuzhou University, Fuzhou, China.

Early accurate diagnosis of patellofemoral pain syndrome (PFPS) is important to prevent the further development of the disease. However, traditional diagnostic methods for PFPS mostly rely on the subjective experience of doctors and subjective feelings of the patient, which do not have an accurate-unified standard, and the clinical accuracy is not high. With the development of artificial intelligence technology, artificial neural networks are increasingly applied in medical treatment to assist doctors in diagnosis, but selecting a suitable neural network model must be considered.

Changing Stride Frequency Alters Average Joint Power and Power Distributions during Ground Contact and Leg Swing in Running.

Med Sci Sports Exerc 2021 Apr 27. Epub 2021 Apr 27.

Human Movement Biomechanics research group, Department of Movement Science, KU Leuven, Belgium Department of Kinesiology, University of Massachusetts, Amherst, MA.

Purpose: Runners naturally adopt a stride frequency closely corresponding with the stride frequency that minimizes energy consumption. While the concept of self-optimization is well recognized, we lack mechanistic insight in the association between stride frequency and energy consumption. Altering stride frequency affects lower extremity joint power, however these alterations are different between joints, possibly with counteracting effects on the energy consumption during ground contact and swing.

The importance of a consistent workflow to estimate muscle-tendon lengths based on joint angles from the conventional gait model.

Gait Posture 2021 Apr 27;88:1-9. Epub 2021 Apr 27.

Center for Gait and Motion Analysis, Gillette Children's Specialty Healthcare, St Paul, MN, USA; Department of Orthopedic Surgery, University of Minnesota, Minneapolis, MN, USA.

Background: Musculoskeletal models enable us to estimate muscle-tendon length, which has been shown to improve clinical decision-making and outcomes in children with cerebral palsy. Most clinical gait analysis services, however, do not include muscle-tendon length estimation in their clinical routine. This is due, in part, to a lack of knowledge and trust in the musculoskeletal models, and to the complexity involved in the workflow to obtain the muscle-tendon length. Read More

The metabolic and mechanical consequences of altered propulsive force generation in walking.

J Biomech 2021 Apr 18;122:110447. Epub 2021 Apr 18.

Joint Department of Biomedical Engineering, University of North Carolina at Chapel Hill and North Carolina State University, Chapel Hill, NC, USA. Electronic address:

Older adults walk with greater metabolic energy consumption than younger for reasons that are not well understood. We suspect that a distal-to-proximal redistribution of leg muscle demand, from muscles spanning the ankle to those spanning the hip, contributes to greater metabolic energy costs. Recently, we found that when younger adults using biofeedback target smaller than normal peak propulsive forces (F), they do so via a similar redistribution of leg muscle demand during walking.

Contribution of passive moments to inter-segmental moments during gait: A systematic review.

J Biomech 2021 Apr 18;122:110450. Epub 2021 Apr 18.

Univ Lyon, Univ Gustave Eiffel, LBMC UMR T9406, F69622 Lyon, France.

Inter-segmental moments computed by inverse dynamic during gait come from active moments, due to muscle contraction, but also from passive moments, resulting from the resistance of the periarticular structures to their deformation. The evaluation of the proportion of the inter-segmental moments that can be attributed to passive moments has led to divergent results. Thus, the purpose of this study was to systematically search and synthesize the evidence of the contribution of passive moments to inter-segmental moments during healthy and pathological gait.

College of Education, Hankuk University of Foreign Studies, Seoul 02450, Korea.

: The jumping kick of Taekwondo was a unilateral exercise that repeatedly moves in one direction. The exercise was exposed to the risk of injury due to the heavy ground reaction force and load in the landing. The first purpose of this study was to compare the impact force (IF), peak vertical ground reaction force (PVGRF), vertical loading rate (VLR), vertical stiffness (VS), and landing foot angle (LFA) during the landing of the jumping kick according to the experience of lower injury.

Locomotion Mode Recognition Algorithm Based on Gaussian Mixture Model Using IMU Sensors.

Sensors (Basel) 2021 Apr 15;21(8). Epub 2021 Apr 15.

Department of Mechatronics Engineering, Hanyang University, 55 Hanyangdaehak-ro, Sangnok-gu, Ansan-si 15588, Gyeonggi-do, Korea.

The number of elderly people has increased as life expectancy increases. As muscle strength decreases with aging, it is easy to feel tired while walking, which is an activity of daily living (ADL), or suffer a fall accident. To compensate the walking problems, the terrain environment must be considered, and in this study, we developed the locomotion mode recognition (LMR) algorithm based on the gaussian mixture model (GMM) using inertial measurement unit (IMU) sensors to classify the five terrains (level walking, stair ascent/descent, ramp ascent/descent).
