Dynamic simulation of knee joint mechanics: individualized multi-moment finite element modelling of patellar tendon stress during landing.

Patellar tendinopathy is prevalent in sports requiring high jumping demands, and understanding the in vivo biomechanical behavior of the patellar tendon (PT) during landing is crucial for developing effective injury prevention and rehabilitation strategies. This study investigates the in vivo biomechanical behavior of the PT during the landing phase of a stop-jump task, integrating musculoskeletal modelling, finite element analysis (FEA), and a high-speed dual fluoroscopic imaging system (DFIS). A subject-specific knee joint model was constructed from CT, MRI, and dynamic X-ray data for a 27-y

Asymmetry, lumbo-pelvic hip complex and injury in european soccer players.

Human movement, in its synergistic, functional, and stabilizing nature, necessitates a balance of muscle length and strength between the mus … ation, and postural/dysfunctional patterns. These patterns could increase the risk of injury to the musculoskeletal system, particularly during the return-to-sport process after an injury. In contact/collision sports like soccer, asymmetrical imbalances within the lumbo-pelvic-hip complex have been linked to dysfunctional states that affect lower limb alignment. This ca …

Barycentremetry, spine disorders, posture and motion analysis.

PURPOSE OF THE RESEARCH: Prevention of spine disorders and their management require better understanding of related biomechanical issues. While tremendous progress has been performed for musculoskeletal modelling of the spine, subject specific modelling of the gravitational loads and their effects on the spine is still an issue. Recently, 3D reconstruction of the skeleton from biplanar head to feet X-rays in erect position has been completed by the external body envelope. An approach named "barycentremetry" has been proposed, based on density models to estimate the mass and centre of mass of e

Digital Approaches for a Reliable Early Diagnosis of Psoriatic Arthritis.

Psoriatic arthritis (PsA) is a chronic inflammatory disease that develops in up to 30% of patients with psoriasis. In the vast majority of cases, cutaneous symptoms precede musculoskeletal complaints. Progression from psoriasis to PsA is characterized by subclinical synovio-entheseal inflammation and often non-specific musculoskeletal symptoms that are frequently unreported or overlooked. With the development of increasingly effective therapies and a broad drug armamentarium, prevention of arthritis development through careful clinical monitoring has become priority. Identifying high-risk psor

Estimating Human Upper Limb Impedance Parameters From a State-of-the-Art Computational Neuromusculoskeletal Model.

The human neuro-musculoskeletal system constantly deploys passive (e.g., posture adjustment) and active (e.g., muscle co-contraction) control strategies to regulate upper limb impedance and stability while interacting with the outside world. Upper limb impedance has been assessed through in vivo experiments and model-based simulations. The experiments are practically limited to small samples of able-bodied subjects and few limb postures, and model-based approaches have mostly used simplified upper limb models. Our objective was to develop and validate a computational approach to estimate upper…

The immediate effects of kinesiology taping on cutaneous blood flow in healthy humans under resting conditions: A randomised controlled repeated-measures laboratory study.

BACKGROUND: Kinesiology taping (KT) is used in musculoskeletal practice for preventive and rehabilitative purposes. It is claimed that KT improves blood flow in the microcirculation by creating skin convolutions and that this reduces swelling and facilitates healing of musculoskeletal injuries. There is a paucity of physiological studies evaluating the effect of KT on cutaneous blood microcirculation. OBJECTIVES: The purpose of this parallel-group controlled laboratory repeated measures design study was to evaluate the effects of KT on cutaneous blood microcirculation in healthy human adults

Measures of Juvenile Fibromyalgia.

Juvenile fibromyalgia (JFM) is a chronic and debilitating noninflammatory musculoskeletal pain syndrome that is typically diagnosed in adolescence. There are no specific medical tests or disease markers to diagnose the condition, and classification is based on patient report of pain and other associated symptoms after ruling out other underlying medical causes. JFM can be disabling in multiple life domains and therefore, a multidimensional assessment of JFM is recommended to gain a full picture of the extent of JFM symptoms along with their impact on physical and emotional functioning and qual

Functional and oncological outcomes of limb-salvage surgery for foot and ankle tumors.

BACKGROUND: Limb-salvage surgery has become the backbone treatment for musculoskeletal tumors in the last decades. However, limb-salvage with safe margins for tumors of the foot and ankle is challenging, due to the complex anatomy of this region.
