Abstract

This is a PDF file of an article that has undergone enhancements after acceptance, such as the addition of a cover page and metadata, and formatting for readability, but it is not yet the definitive version of record. This version will undergo additional copyediting, typesetting and review before it is published in its final form, but we are providing this version to give early visibility of the article.

Muscle Forces during Weight-Bearing Exercises in Medial Knee Osteoarthritis and Varus Malalignment: A Cross-Sectional Study

“…Our cohort performed a squat more slowly than a younger, healthy cohort (cohort: descent 12 cm·s −1 , ascent 15 cm·s −1 (Supplemental Table 1, Supplemental Digital Content 1, Spatiotemporal, kinematic, and kinetic measures for walking and exercise tasks, http://links.lww.com/MSS/C612); control: descent 58 cm·s −1 , ascent 69 cm·s −1 (33)). Indeed, it is likely that movement speed will influence peak MTCF, as it does during analysis of walking (29). Importantly, the self-selected walking speed of the cohort was 1.24 m·s −1 (±0.13), which is consistent with self-selected walking speeds in other knee OA studies (mean range, 1.08–1.26 m·s −1 ) (9,18,21,22).…”

Tibiofemoral contact force differences between flat flexible and stable supportive walking shoes in people with varus-malaligned medial knee osteoarthritis: A randomized cross-over study

“…The peak (BW) and impulse (BW . s) were extracted [ 18 , 39 ]. The loading phase of gait was defined as the point from initial contact to the first peak of the load variable [ 21 ].…”

“…The use of the external KAM to infer internal joint load sharing is limited because the KAM does not account for the contribution of muscle loading in its estimates [ 16 – 18 ]. To gain insight into the internal mechanics of the joint, electromyogram (EMG)-informed neuromusculoskeletal modelling can be used, which considers both muscle and external load contributors to estimate MTCF [ 17 ].…”

Toward Tailored Rehabilitation by Implementation of a Novel Musculoskeletal Finite Element Analysis Pipeline

“…Nevertheless, remarkable efforts are made to develop knee joint MS-FE models capable of incorporating a 12 degrees of freedom (DoFs) knee joint [21], [23], [29]- [33], complex soft tissue material models [21], [34], [35], and subject's muscle activation patterns (EMG-assistance) [36], [37]. However, previous studies have investigated only healthy subjects [21], [34], [38], used simplified joint models in terms of limited DoFs [9], [39], did not include subject-specific joint geometries [9], [38], [39] and muscle activation patterns [22], [23], [32], [34], [38]- [40], neglected crucial joint tissues such as menisci [9], [38], and/or employed simplistic soft tissue material models [31], [38]. To the best of our knowledge, there are no studies that have included the aforementioned complex FRPVE soft-tissue material model in the MS-FE framework to characterize detailed knee cartilage mechanics in different functional activities other than walking gait.…”
