BACKGROUND: Prevention of knee osteoarthritis (OA) following anterior cruciate ligament (ACL) rupture and reconstruction is vital. Risk of postreconstruction knee OA is markedly increased by concurrent meniscal injury. It is unclear whether reconstruction results in normal relationships between tibiofemoral contact forces and cartilage morphology and whether meniscal injury modulates these relationships. HYPOTHESES: Since patients with isolated reconstructions (ie, without meniscal injury) are at lower risk for knee OA, we predicted that relationships between tibiofemoral contact forces and cartilage morphology would be similar to those of normal, healthy knees 2 to 3 years postreconstruction...

Physical therapists often assess and treat patients whose pain and disability stem from impaired mobility of the peripheral nervous system. Neural mobilization is a movement-based therapy, applied manually or via exercise. The nerve is mobilized relative to adjacent structures, with the aim of reducing symptoms through mechanisms that may be mechanical or neurophysiologic. A new systematic review published in the September 2017 issue of JOSPT includes 40 studies of neural mobilization in various neuromusculoskeletal conditions...

On the quest to bring function of prosthetic legs closer to their biological counterparts, intuitive interplay of their control with the user's impedance modulation is key. We present two control features to enable more physiological and more user-adaptive control of prosthetic legs: a neuromusculoskeletal impedance model (NeurImp) including a reflexive component, and a human model reference adaptive controller (HuMRAC), which can be combined with the former. In stance-phase simulations, the NeurImp allowed to control a prosthetic leg with physiological knee joint angle and moment...

BACKGROUND: Physical activity (PA) is a health determinant among middle-aged and older adults. In contrast, poor health is expected to have a negative impact on PA. This study sought to assess to what extent specific International Classification of Functioning, Disability and Health (ICF) health components were associated with PA among older adults. METHODS: We used a sample of 864 persons aged ≥50 years, positively screened for disability or cognition in a cross-sectional community survey in Spain...

Neuromusculoskeletal disorders affecting walking ability are often difficult to manage, in part due to limited understanding of how a patient's lower extremity muscle excitations contribute to the patient's lower extremity joint moments. To assist in the study of these disorders, researchers have developed electromyography (EMG) driven neuromusculoskeletal models utilizing scaled generic musculoskeletal geometry. While these models can predict individual muscle contributions to lower extremity joint moments during walking, the accuracy of the predictions can be hindered by errors in the scaled geometry...

Quantifying neural and non-neural contributions to increased joint resistance in spasticity is essential for a better understanding of its pathophysiological mechanisms and evaluating different intervention strategies. However, direct measurement of spasticity-related manifestations, e.g., motoneuron and biophysical properties in humans, is extremely challenging. In this vein, we developed a forward neuromusculoskeletal model that accounts for dynamics of muscle spindles, motoneuron pools, muscle activation and musculotendon of wrist flexors and relies on the joint angle and resistant torque as the only input measurement variables...

The history and physical examination are important keys to diagnosis and treatment of patients with chronic pelvic pain. The comprehensive history should include questioning regarding patient's pain complaint and a thorough history and review of any body system that may be involved, including neuromusculoskeletal, obstetric, gynecologic, gastrointestinal, urologic, dermatologic, infectious, oncologic, and psychiatric. The physical examination should also follow a focused systems-based approach and includes examination of gastrointestinal, dermatologic, neurologic, and musculoskeletal (including lumbosacral spine, sacroiliac joints, pelvis, and hips) systems, and the pelvic floor (internal and external examination, including neuromuscular anatomy)...

Cervical Dystonia (CD) is a rare movement disorder characterized by an abnormal head position. This cross-sectional study describes the health status and severity of disability using an internationally agreed language by applying the International Classification of Functioning, Disability and Health (ICF). Two disease-specific rating scales were administered to 30 patients with CD. By linking the individual answers to the ICF model, the frequency and severity of reported impairments and restrictions were estimated using a count-based method...

Despite the technological progress in robotics achieved in the last decades, prosthetic limbs still lack functionality, reliability, and comfort. Recently, an implanted neuromusculoskeletal interface built upon osseointegration was developed and tested in humans, namely the Osseointegrated Human-Machine Gateway. Here, we present an embedded system to exploit the advantages of this technology. Our artificial limb controller allows for bioelectric signals acquisition, processing, decoding of motor intent, prosthetic control, and sensory feedback...

Biofeedback assisted rehabilitation and intervention technologies have the potential to modify clinically relevant biomechanics. Gait retraining has been used to reduce the knee adduction moment, a surrogate of medial tibiofemoral joint loading often used in knee osteoarthritis research. In this study we present an electromyogram-driven neuromusculoskeletal model of the lower-limb to estimate, in real-time, the tibiofemoral joint loads. The model included 34 musculotendon units spanning the hip, knee, and ankle joints...

Although orthopaedic manual therapy (OMT) has existed for decades, and although a recent Belgian Royal Decree, published in 2014, recognized it as a particular professional qualification in physiotherapy for the treatment of neuromusculoskeletal dysfunctions, OMT remains little known by patients, but also by healthcare professionals. Yet, this professional qualification, based on clinical reasoning, using highly specific treatments, guided by the best available scientific and clinical evidence and the specific biopsychosocial characteristics of each patient, is the subject of a growing number of scientific studies pointing out its effectiveness...

Rigid body dynamics and soft tissue loads are solved simultaneously in a cosimulation framework to couple musculoskeletal dynamics and tissue mechanics. The goal of this work was to implement a validated, open-source cosimulation framework of the knee to determine how this coupling affects computed cartilage loads. The kinematic knee joint of a generic whole body model in the open-source software OpenSim was replaced by a previously developed discrete element knee model that consisted of a six degree of freedom (dof) tibiofemoral joint and one dof patellofemoral joint...
