“…A major discrepancy between simulations and fluoroscopy existed in the results of talocrural inversion/eversion, where the model predicted a larger talocrural excursion on the coronal plane than fluoroscopy. A possible explanation is that the small angularity of the X-ray projectors and image matching techniques utilised in the radiological study [ 35 ] might not capture the rearfoot motions on the coronal planes as sufficiently as on the sagittal plane. Meanwhile, our foot model with structural and material simplifications in the ankle joint tended to overestimate the ankle motions.…”

“…Because the study applied a dynamic simulation approach, we also validated the model by comparing three-dimensional ankle joint motions with those measured using dynamic biplane fluoroscopy—a measurement modality that is normally considered the gold standard method for tracking bone movements. A radiographic study [ 35 ] on hindfoot kinematics during gait was selected as the source of fluoroscopic results because the study recruited healthy adults with average anthropometrics and walking speeds similar to those of our participant.…”

“…During the past decades, numerous studies have been conducted on AJC kinematics. Among them, Optical Motion Capture (OMC) techniques and multisegmental foot models have been widely used in related research [7][8][9][10][11][12][13]; however, accurate measurement of the 3D motion of the tibiotalar and subtalar using the OMC is difficult to achieve because of the difficulty in placing the corresponding landmarks of the hindfoot [14,15]. In particular, the talus is surrounded by ligaments and muscles and lacks external markers, making it difficult to accurately measure its movement with skin markers.…”

Intrinsic Kinematics of the Tibiotalar and Subtalar Joints during Human Walking based on Dynamic Biplanar Fluoroscopy

Accurate knowledge of the kinematics of the in vivo Ankle Joint Complex (AJC) is critical for understanding the biomechanical function of the foot and assessing postoperative rehabilitation of ankle disorders, as well as an essential guide to the design of ankle–foot assistant devices. However, detailed analysis of the continuous 3D motion of the tibiotalar and subtalar joints during normal walking throughout the stance phase is still considered to be lacking. In this study, dynamic radiographs of the hindfoot were acquired from eight subjects during normal walking. Natural motions with six Degrees of Freedom (DOF) and the coupled patterns of the two joints were analyzed. It was found that the movements of the two joints were mostly in opposite directions (including rotation and translation), mainly in the early and late stages. There were significant differences in the Range of Motion (ROM) in Dorsiflexion/Plantarflexion (D/P), Inversion/Eversion (In/Ev), and Anterior–Posterior (AP) and Medial–Lateral (ML) translation of the tibiotalar and subtalar joints (p < 0.05). Plantarflexion of the tibiotalar joint was coupled with eversion and posterior translation of the subtalar joint during the impact phase (R2 = 0.87 and 0.86, respectively), and plantarflexion of the tibiotalar joint was coupled with inversion and anterior translation of the subtalar joint during the push-off phase (R2 = 0.93 and 0.75, respectively). This coordinated coupled motion of the two joints may be a manifestation of the AJC to move flexibly while bearing weight and still have stability.

“…All data were time-normalized and filtered with an adaptive low-pass Butterworth filter with a cut-off frequency of 20 Hz (MATLAB, R2018a, MathWorks, Natick, United States). The stance phase was defined as the time interval from the instant of touchdown, which was determined as the instant vGRF exceeding a threshold of 15 N ( Welte et al, 2018 ), to the instant of take-off ( Yang et al, 2021 ). Specifically, the stance phase was divided into four phases: early stance (0–20%), mid-stance (20–55%), propulsion (55–85%), and late stance (85–100%) ( Welte et al, 2021 ).…”

Accurately obtaining the in vivo motion of the medial longitudinal arch (MLA), first metatarsophalangeal joint (MTPJ), and plantar fascia (PF) is essential for analyzing the biomechanics of these structures in different running strike patterns. Most previous studies on the biomechanics of the MLA, first MTPJ, and PF have been based on traditional skin-marker–based motion capture, which cannot acquire the natural foot motion. Therefore, this study aimed to 1) describe the movement of the MLA, first MTPJ, and PF during running by using the high-speed dual fluoroscopic imaging system (DFIS) and 2) explore changes of the in vivo kinematics of the MLA and first MTPJ, and the length of the PF during the stance phase of running with different foot strike patterns. Fifteen healthy male runners all of whom ran with a regular rearfoot strike (RFS) pattern were required to run with forefoot strike (FFS) and RFS patterns. Computed tomography scans were taken from each participant’s right foot for the construction of 3D models (the calcaneus, first metatarsal, and first proximal phalanges) and local coordinate systems. A high-speed DFIS (100 Hz) and 3D force platform (2,000 Hz) were used to acquire X-ray images of the foot bones and ground reaction force data during the stance phase of running (3 m/s ± 5%) simultaneously. Then, 3D-2D registration was used to obtain the in vivo kinematic data of the MLA and first MTPJ and the length of the PF. When compared with RFS, in FFS, 1) the range of motion (ROM) of the medial/lateral (5.84 ± 5.61 mm vs. 0.75 ± 3.38 mm, p = 0.002), anterior/posterior (14.64 ± 4.33 mm vs. 11.18 ± 3.56 mm, p = 0.010), plantarflexion/dorsiflexion (7.13 ± 3.22° vs. 1.63 ± 3.29°, p < 0.001), and adduction/abduction (−3.89 ± 3.85° vs. −0.64 ± 4.39°, p = 0.034) motions of the MLA were increased significantly; 2) the ROM of the anterior/posterior (7.81 ± 2.84 mm vs. 6.24 ± 3.43 mm, p = 0.003), superior/inferior (2.11 ± 2.06 mm vs. −0.57 ± 1.65 mm, p = 0.001), and extension/flexion (−9.68 ± 9.16° vs. −5.72 ± 7.33°, p = 0.018) motions of the first MTPJ were increased significantly; 3) the maximum strain (0.093 ± 0.023 vs. 0.075 ± 0.020, p < 0.001) and the maximum power (4.36 ± 1.51 W/kg vs. 3.06 ± 1.39 W/kg, p < 0.001) of the PF were increased significantly. Running with FFS may increase deformation, energy storage, and release of the MLA and PF, as well as the push-off effect of the MTPJ. Meanwhile, the maximum extension angle of the first MTPJ and MLA deformation increased in FFS, which showed that the PF experienced more stretch and potentially indicated that FFS enhanced the PF mechanical responses.
