The ITM and ITCR's medial rotator moment arms peak at hip angles of 300 , then reduce; a pattern qualitatively matched by B.A.S.'s data.

The two AMB muscles in our model have peak adductor moment arms at distinct flexion angles (30 and 80 ), then lower. B.A.S.'s information (modified data shown; Karl T. Bates, pers. comm., 2015) normally follow our AMB1 muscle's. Our IC muscle includes a similar adductor moment arm curve as our AMB2, plus a related divergence from B.A.S.'s results, which remain close to a zero moment arm. Our IL muscle parts (ILa,p) agree effectively with B.A.S.'s, displaying them to act as abductors. Each our ILFB muscle components (ILFBa,p) have tiny variation in their hip abductor actions, whereas B.A.S.'s representation had a 100 larger moment arm but otherwise was comparable. The OM muscle, which runs pretty close towards the plane from the acetabulum, is definitely an adductor at extended joint angles and an abductor at flexed angles in each our model and in B.A.S.'s information. Whilst the ISF muscle is pretty much exclusively a hip abductor in our model, it was exclusively an adductor within the B.A.S. model. The FCL and FCM muscles examine onlyHutchinson et al.

See caption for Fig. 9.qualitatively amongst our information and B.A.S.'s, remaining as hip abductors. It can be noteworthy that throughout the complete ranges of hip motion we examined, most muscle tissues would act as hip abductors; the dorsal AMB2 and IC muscles are the only regularly strong hip adductors (Fig. 14; Figs. S3 and S4). Uniarticular "deep dorsal" and antagonistic muscles show equivalent trends as the above muscle tissues for adduction/abduction Urement that the aforementioned studies {can be|may be|could capacities (Fig. 15). The IFI has weak adductor action, vs. a smaller, near-zero value (but related trend) in B.A.S.'s information, whereas our information and B.A.S.'s agree effectively around the hip abductor moment arm with the IFE. Our representations from the ITCa/p muscle components switch from abduction to adduction function as hip flexion surpasses 450 ; B.A.S.'s model did this switch to a stronger degree. Postacetabular muscles like the CFP and PIFML in our model are nearly exclusively hip abductors, significantly as in B.AS.'s model. Lastly, our benefits also generally have a excellent match to B.A.S.'s within the case in the ITM and ITCR muscles, which convert from abductor to adductor action at 100 hip angles (Fig. 15). We only focused on flexion/extension moment arms for additional distal joints, starting using the knee (Figs. 16 and 17).MomentHutchinson et al.
