“…the averaged concordance across the 5 gait cycles was 68.6% with a standard deviation of 4.7%. Moreover, the present model and method applied to the present gait data were able to replicate findings in the recent literature concerning the patterns and distributions of the contributions of musculo-tendon forces to the superior-inferior component of 3D hip contact force [16], tibiofemoral total contact force [14] and the vertical component of 3D ground reaction force [7] during the stance phase of gait ( Fig. 1).…”

“…This could provide insights into pathologic gait patterns [3], as well as the progression of joint disorders such as osteoarthritis [1,4]. Several studies have analysed how musculo-tendon forces contribute to ground reaction force [2,3,[5][6][7], acceleration of the centre of mass [8][9][10][11], whole-body angular momentum [12], angular accelerations of joints [13], linear and angular accelerations of segments [6], and joint moment at the ankle, knee and hip [2,4,14,15]. Studies have also analysed how musculo-tendon forces contribute to 3D hip joint contact force [2,16], the vertical component of 3D tibiofemoral joint contact force [2,4,14,[17][18][19], the vertical component of 3D ankle joint contact force [2] and femur force [20].…”

Individual muscle contributions to ground reaction and to joint contact, ligament and bone forces during normal gait

Recent developments in musculoskeletal modelling have enabled numerous studies to explore how individual muscles contribute to progression, support and mechanical loading during gait. However, the literature still lacks data on the contributions of musculo-tendon forces to several structures, making it difficult to determine the primary contributors. The aim of the present study was thus to provide a comprehensive investigation of individual muscle contributions to ground reaction (i.e. 3D ground reaction force and moment), and to joint contact, ligament and bone (i.e. compression-traction of bony segments) forces during normal gait. We used a 3D lower limb musculoskeletal model coupled with a static optimisation method using a pseudo-inverse, which indeed yielded data on individual muscle contributions currently missing from the literature. We report the individual muscle contributions to 1) 3D ground reaction force and moment, 2) hip, tibiofemoral, patellofemoral, and ankle joint contact forces, 3) tibiofemoral and ankle ligament forces and 4) femur, patella and tibia bone forces. In line with the recent literature, the primary contributors are the vastii, gluteus medius, soleus, rectus femoris, gemellus, quadratus femoris, gluteus maximus and adductors. While the current observations are made on a generic model, the present method offers a comprehension tool that can shed light on the underlying mechanisms governing the musculoskeletal system.

Mechanical Loading of the Femoral Neck in Human Locomotion

Advancing age and reduced loading are associated with a reduction in bone formation. Conversely, loading increases periosteal apposition and may reduce remodeling imbalance and slow age-related bone loss, an important outcome for the proximal femur, which is a common site of fracture. The ability to take advantage of bone's adaptive response to increase bone strength has been hampered by a lack of knowledge of which exercises and specific leg muscles load the superior femoral neck: a common region of microcrack initiation and progression following a sideways fall. We used an in vivo method of quantifying focal strains within the femoral neck in postmenopausal women during walking, stair ambulation, and jumping. Relative to walking, stair ambulation and jumping induced significantly higher strains in the anterior and superior aspects of the femoral neck, common regions of microcrack initiation and progression following a fall. The gluteus maximus, a hip extensor muscle, induced strains in the femoral neck during stair ambulation and jumping, in contrast to walking which induced strains via the iliopsoas, a hip flexor. The ground reaction force was closely associated with the level of strain during each task, providing a surrogate indicator of the potential for a given exercise to load the femoral neck. The gluteal muscles combined with an increased ground reaction force relative to walking induce high focal strains within the anterosuperior region of the femoral neck and therefore provide a target for exercise regimens designed to slow bone loss and maintain or improve microstructural strength.

Sex‐related differences in neuromuscular control: Implications for injury mechanisms or healthy stabilisation strategies?

Sex-related differences in neuromuscular activation have been previously identified and are thought to be an underlying contributor to the ACL injury mechanism. During dynamic tasks evaluating the role of muscle action as it relates to joint stability is difficult since individual muscle contributions to force generation are confounded by biomechanical factors of movement. The purpose of this study was to examine sex-related differences in knee muscle action during a weight-bearing isometric exercise and identify the stabilising role of these muscles. Healthy young adults stood with their dominant leg in a boot fixed to a force platform. A force matching protocol required participants to modulate normalised ground reaction forces in various combinations of anterior-posterior, medial-lateral loads while maintaining a constant joint position. Normalised electromyographic data of eight muscles crossing the knee joint were displayed in polar plots. Patterns were quantified with an orientation analysis and mean activation magnitudes were computed. Females demonstrated symmetrical activation patterns with significantly greater activation in the rectus femoris (p ¼ 0.037), lateral gastrocnemius (p ¼ 0.012), and tensor fascia lata (p ¼ 0.005) compared to males. High between-subject reliability (ICC ¼ 0.772-0.977) was observed across groups suggesting we have identified fundamental sex-related differences in knee joint stabilisation strategies. ß
