Reducing the Complexity of Musculoskeletal Models Using Gaussian Process Emulators

Applied Sciences, 2022
Musculoskeletal models (MSKMs) are used to estimate the muscle and joint forces involved in human locomotion, often associated with the onset of degenerative musculoskeletal pathologies (e.g., osteoarthritis).

Assessment of Motion and Muscle Activation Impacts on Low Back Pain during Pregnancy Using an Inertial Measurement Unit

Applied Sciences, 2020
Specific physiological changes during pregnancy exert excessive strain on muscles such as the erector spinae (ES) and contribute to low back pain (LBP).

Shoulder Positioning during Superior Capsular Reconstruction: Computational Analysis of Graft Integrity and Shoulder Stability

Biology, 2021
The shoulder position during fixation of the graft may be a key factor impacting the outcome of arthroscopic superior capsular reconstruction (ASCR) in irreparable rotator cuff tears (IRCTs).

Engineered miniaturized models of musculoskeletal diseases [PDF]

Drug Discovery Today, 2016
The musculoskeletal system is an incredible machine that protects, supports and moves the human body. However, several diseases can limit its functionality, compromising patient quality of life. Designing novel pathological models would help to clarify the mechanisms driving such diseases, identify new biomarkers and screen potential drug candidates ...

A Conceptual Blueprint for Making Neuromusculoskeletal Models Clinically Useful

Applied Sciences, 2021
The ultimate goal of most neuromusculoskeletal modeling research is to improve the treatment of movement impairments. However, even though neuromusculoskeletal models have become more realistic anatomically, physiologically, and neurologically over the ...

Muscle mass in musculoskeletal models [PDF]

Journal of Biomechanics, 2010
Most current models of musculoskeletal dynamics lump a muscle's mass with its body segment, and then simulate the dynamics of these body segments connected by joints. As shown here, this popular approach leads to errors in the system's inertia matrix and hence in all aspects of the dynamics.

Modeling the Dynamics of Children’s Musculoskeletal Fitness

International Journal of Environmental Research and Public Health, 2023
This study models children’s musculoskeletal fitness (MSF) developmental trajectories and identifies individual differences related to effects of time-invariant, as well as time-varying covariates. A total of 348 Portuguese children (177 girls) from six age cohorts were followed for three years.

A rare case of osteonecrosis of patella following quadriceps distractive lengthening for neglected non-union patella

Journal of Orthopaedic Reports
Neglected patella fracture non-unions are extremely rare and contraction of the quadriceps femoris muscle makes it immensely difficult to operate non-union patella after a long time.

Estimation of the hip joint contact force using 3-dimensional model analysis and stress analysis of acetabular dysplasia around shelf acetabuloplasty

Nihon Kikai Gakkai ronbunshu, 2017
Acetabular dysplasia describes an underdeveloped or shallow, upwardly sloping acetabulum, which may occur with varying degrees of deformity of the proximal femur such as excessive femoral neck anteversion, coxa valga or femoral neck cam deformity ...

Wrist Torque Estimation by Combining Motor Unit Discharges With Musculoskeletal Model

IEEE Transactions on Neural Systems and Rehabilitation Engineering
The application of electromyography (EMG) decomposition techniques in myoelectric control has gradually increased. However, most decomposition-based control schemes rely on machine learning, lacking interpretation of the biological mechanisms underlying ...
