“…While in another observation of 15 healthy subjects performing barefoot and shod over ground running trials, Hoerzer et al [ 26 ] notice that gait asymmetry of the participants is reduced when running in shoes as compared to running barefoot. In the present study, the kinetics calculations for force and moment perspectives are reflections of the ground reaction force and kinematics and can be affected by the use of wedges, insoles, or other devices, especially in the sagittal plane [ 27 , 28 ], where lower limb joints have maximum extent of motion. In addition, ground reaction forces have large transient spikes (i.e., foot contact) and therefore the sole of the shoe helps to filter/smooth these peaks out, so small shifts in the timing of the contact peaks are reduced by the compliance of the shoe heel, which will make less variability in the ground reaction force for the shod conditions and thus a lower symmetry index.…”

We aim to test how well modern nonhabitual barefoot people can adapt to barefoot and Minimalist Bare Foot Technology (MBFT) shoes, in regard to gait symmetry. 28 healthy university students (22 females/6 males) were recruited to walk on a 10-meter walkway randomly on barefoot, in MBFT shoes, and in neutral running shoes at their comfortable walking speed. Kinetic and kinematic data were collected using an 8-camera motion capture system. Data of joint angles, joint forces, and joint moments were extracted to compute a consecutive symmetry index. Compared to walking in neutral running shoes, walking barefoot led to worse symmetry of the following: ankle joint force in sagittal plane, knee joint moment in transverse plane, and ankle joint moment in frontal plane, while improving the symmetry of joint angle in sagittal plane at ankle joints and global (hip-knee-ankle) level. Walking in MBFT shoes had intermediate gait symmetry performance as compared to walking barefoot/walking in neutral running shoes. We conclude that modern nonhabitual barefoot adults will lose some gait symmetry in joint force/moment if they switch to barefoot walking without fitting in; MBFT shoe might be an ideal compromise for healthy youth as regards gait symmetry in walking.

“…This observation was also proved by rehabilitation studies, indicating patients struggle to achieve this after THR ( 26 ). The cross-legged sitting position demands a greater range of motion with hip flexion, abduction, and external rotation ( 27 ). Patients in our cohort were satisfied with their functional outcomes with 88% (22/25) of patients being able to either sit cross-legged or sit on the floor.…”

IntroductionIn the Middle East, severe developmental dysplasia of the hip with subsequent high dislocation is often seen. We assessed the efficiency of total hip replacement (THR) with subtrochanteric shortening femoral osteotomy and trochanteric advancement in this population.MethodsThis prospective study assessed 25 female patients with symptomatic and severe (Crowe IV). Pre- and postoperative Harris hip score (HHS) and Oxford hip score (OHS) were performed alongside assessment of leg length discrepancy (LLD) and the ability to sit in a cross-legged position.ResultsThe mean HHS and OHS improved pre-operatively at 1 and 10 years, respectively (p-value < 0.001). The mean postoperative LLD was 3 mm (0–8 mm). Functionally, 22/25 patients were able to sit cross-legged. None of the 25 hips underwent revision during this period.ConclusionTotal hip replacement with subtrochanteric shortening osteotomy in combination with trochanteric advancement is sufficient for the management of Crowe type IV hips in this population.

“…PCA was performed based on a previous study 15 and is described in detail by Soares et al 17 (Figure 1). In summary, the aim of PCA is to summarize the information contained in 100% of the stance phase—which is represented by 100 variables—in a smaller number of components that explain the greater variance through linear combinations from those variables, by considering each 1% in time axis as one variable (100 variables—matrix X and A below), and to represent the full waveform by a smaller number of components (PC model—matrix Z ).…”
