Bone anchored markers using intracortical bone pins are one of the few available methods for analyzing skeletal motion during human gait in-vivo without errors induced by soft tissue artifacts.However, bone anchored markers require local anesthesia and may alter the motor control and motor output during gait. The purpose of this study was to examine the effect of local anesthesia and the use of bone anchored markers on typical gait analysis variables. Five subjects were analyzed in two different gait analysis sessions. In the first session, a protocol with skin markers was used. In the second session, bone anchored markers were added after local anesthesia was applied. For both sessions, three dimensional infrared kinematics of the calcaneus and tibia segments, ground reaction forces, and plantar pressure data were collected. 95% confidence intervals and boxplots were used to compare protocols and assess the data distribution and data variability for each subject. Although considerable variation was found between subjects, withinsubject comparison of the two protocols revealed non-systematic effects on the target variables.Two of the five subjects walked at reduced gait speed during the bone pin session, which explained the between-session differences found in kinetic and kinematic variables. The remaining three subjects did not systematically alter their gait pattern between the two sessions. Results support the hypothesis that local anesthesia and the presence of bone pins still allow a valid gait pattern to be analyzed.

“…The kinematic results are compared against the in-vivo foot kinematics data of Lundgren et al (2008). In this work they used bone anchored external markers to describe the kinematics, a more direct measurement of skeletal kinematics than skin mounted markers which are prone to soft tissue artefacts.…”

“…In addition, the geometry of the intrinsic and extrinsic muscles were included as well as the major ligaments. Both models were validated by comparing inverse kinematics for gait with joint kinematics published in literature (Lundgren et al 2008). Furthermore, the 8DOF model was used to evaluate inverse dynamics and ligament strain during gait.…”

Multibody simulations of human motion require representative models of the anatomical structures. A model that captures the complexity of the foot is still lacking. In the present work, two detailed 3D multibody foot-ankle models generated based on CT scans using a semi-automatic tool are described. The proposed models consists of five rigid segments (talus, calcaneus, midfoot, forefoot and toes), connected by five joints (ankle, subtalar, midtarsal, tarsometatarsal and metatarsophalangeal), one with 15DOF and the other with 8DOF. The calculated kinematics of both models were evaluated using gait trials and compared against literature, both presenting realistic results. An inverse dynamic analysis was performed for the 8DOF model, again presenting feasible dynamic results.

“…In the past years, different foot models for gait kinematics and dynamics studies have been introduced in the literature [6,12,18,20,23,25,27,30,31]. In most of these human gait analyses, ankle joint has been modelled based on a revolute joint [15,19,27], two revolute joints with non-orthogonal axes of rotations [7,9,24], or a spherical joint [26,30,31].…”

“…One-segment [5,31], two-segment [27,30], or three-segment foot models [6] are also proposed in the literature. Some studies suggested more segments for the foot [18,20,23,25], for instance, the eight-segment foot by MacWilliams et al [18]. Most of the multi-segment foot models have been used for kinematics analysis of the foot.…”

In this study, effects of some of the foot modelling assumptions on the ankle kinematics and dynamics are investigated based on the experimental data. For the kinematics analysis, the appropriateness of the stationary axis of rotation of the human ankle flexion is examined. Moreover, an interpolated function which is capable of predicting the directional changes of this axis is proposed. For the dynamics analysis, two main modelling assumptions of the number of the foot segments and the dimension of the foot model are the subject of the study. To this end, the ankle joint torque and power are selected as the comparison indicators and inverse dynamics analyses are carried out. The analyses show that the number of segments of the foot model does not have a considerable effect on the calculated ankle joint torque. On the other hand, the calculated ankle power is highly affected by both of the segmentation and the dimension of the foot model.
