“…However, adaptive gait strategies occur that change toe clearance to permit foot clearance, comfortable locomotion, and vertical balance [14,21]. Similarly, the combination of transverse slope and irregular surface type resulted in obvious gait adaptations.…”

“…Three walking surface types: larger rocks (LR), gravel (G), and hard surface (HS) (structural plywood sheeting), and two walkway configurations, level and sloped (7°) were examined in this study. The slope in this study was chosen as 7° to compare to research reported by others [13] and transverse slope gait adaptations on a 6° slope [14,21].…”

Same level falls continue to contribute to an alarming number of slip/trip/fall injuries in the mining workforce. The objective of this study was to investigate how walking on different surface types and transverse slopes influences gait parameters that may be associated with a trip event. Gait analysis was performed for ten subjects on two orientations (level and sloped) on smooth, hard surface (control) and irregular (gravel, larger rocks) surfaces. Walking on irregular surfaces significantly increased toe clearance compared to walking on the smooth surface. There was a significant (p < 0.05) decrease in cadence (steps/min), stride length (m), and speed (m/s) from control to gravel to larger rocks. Significant changes in external rotation and increased knee flexion while walking on irregular surfaces were observed. Toe and heel clearance requirements increased on irregular surfaces, which may provide an explanation for trip-induced falls; however, the gait alterations observed in the experienced workers used as subjects would likely improve stability and recovery from a trip.

“…However, these biomechanical studies were done using an experimental model that simulated flat ground loading that resembles the stance phase of gait with the foot in the neutral position. Variations in loading during inversion and eversion of the foot are commonly encountered and result in compensatory alterations in gait patterns in healthy subjects [9,10]. In addition, flat ground-loading models do not examine the foot and ankle complex in the frontal (coronal) plane where the subtalar joint contributes to maintain lower limb alignment with a loaded plantar foot position [5].…”

Background While successful subtalar joint arthrodesis provides pain relief, resultant alterations in ankle biomechanics need to be considered, as this procedure may predispose the remaining hindfoot and tibiotalar joint to accelerated degenerative changes. However, the biomechanical consequences of isolated subtalar joint arthrodesis and additive fusions of the Chopart's joints on tibiotalar joint biomechanics remain poorly understood. Questions/purposes We asked: What is the effect of isolated subtalar fusion and sequential Chopart's joint fusions of the talonavicular and calcaneocuboid joints on tibiotalar joint (1) mechanics and (2) kinematics during loading for neutral, inverted, and everted orientations of the foot? Methods We evaluated the total force, contact area, and the magnitude and distribution of the contact stress on the articular surface of the talar dome, while simultaneously tracking the position of the talus relative to the tibia during loading in seven fresh-frozen cadaver feet. Each foot was loaded in the unfused, intact control condition followed by three randomized simulated hindfoot arthrodesis modalities: subtalar, double (subtalar and talonavicular), and triple (subtalar, talonavicular, and calcaneocuboid) arthrodesis. The intact and arthrodesis conditions were tested in three alignments using a metallic wedge insert: neutral (flat), 10°i nverted, and 10°everted. Results Tibiotalar mechanics (total force and contact area) and kinematics (external rotation) differed owing to hindfoot arthrodeses.

Purpose: Little information is available on joint kinematic adaptations during walking on crossslope surfaces (i.e. a surface incline perpendicular to the direction of locomotion). This study aimed to evaluate the effects of cross-slope surfaces on three-dimensional (3D) kinematics of hip, knee, and ankle joints during stance phase of walking.Methods: This is a quasi-experimental study. Ten healthy adult male students were selected through available sampling method and walked along an inclinable walkway in both level (0°) and cross-slope (10°) configurations. The 3D angles of hip, knee, and ankle along with their time of occurrence (the time reaching to the maximum values for each specific joint angle) were analyzed using repeated measures multivariate analysis of variance (MANOVA) by SPSS 17. P<0.05 was considered significant.Results: Knee and ankle joints had the most kinematic adaptations on cross-slope conditions in the sagittal plane, while in the transverse plane angles of hip and knee joints were mainly altered (P<0.05). These adaptations are necessary to adjust the functional leg-length during different stance phases to both maintain a subtle gait pattern and medio-lateral balance. Though significant differences in timing of the joints kinematic events between level and cross-slope walking were observed (P<0.05), their temporal aspects of the kinematic adaptations were more consistent than their magnitude. Conclusion:The information obtained from this study enriches our understanding about the kinematic adaptations of the lower extremity joints in stance phase during level and cross-slope walking.
