Walking is impaired in Pregnancy-related Pelvic girdle Pain (PPP). velocity reduced, and postpartum PPP relative phase between horizontal pelvis thorax rotations was found to be lower at higher velocities, rotational amplitudes tended larger. While attempting confirm these findings for during pregnancy, we wanted identify underlying mechanisms. We compared gait kinematics of 12 healthy pregnant women with PPP, focusing on the transverse segmental rotations, timing amplitude spinal rotations....
The Active Straight Leg Raise (ASLR) is an important test in diagnosing pelvic girdle pain (PGP). It difficult to understand what happens normally during the ASLR, let alone why it would be impaired PGP. In present study, healthy subjects performed ASLR under normal conditions, with weight added above ankle, and while wearing a belt. Activity of abdominal muscles, rectus femoris (RF), biceps (BF) was recorded surface electromyography (EMG), transversus abdominis (TA) fine wire EMG. RF...
Background: Medial patellofemoral ligament (MPFL) reconstruction is associated with a high rate of complications, including recurrent instability and persistent knee pain. Technical errors are among the primary causes these complications. Understanding effect adjusting attachments on length change patterns may help surgeons to optimize graft placement during MPFL reduce failure rates. Purpose: To determine in vivo changes dynamic, weightbearing motion map isometry 3-dimensional wrapping...
Vertical femoral neck fractures in patients younger than 65 years of age often require hip-conserving surgeries. However, traditional fixation strategies using three parallel cannulated screws fail such due to an unfavorable biomechanical environment. This study compared different screw techniques via patient-specific finite element analysis with linear tetrahedral (C3D4) elements. Forty vertical fracture models were created based on computed tomography images obtained from eight healthy...
Empirical research in DEM accuracy assessment has observed that errors are correlated with terrain morphology, sampling density, and interpolation method. However, theoretical reasons for these correlations have not been accounted for. This paper introduces approximation theory adapted from computational science as a new framework to assess the of DEMs interpolated topographic maps. By perceiving generation piecewise polynomial simulation unknown terrain, overall is described by maximum...
Psoas function is a topic of considerable relevance in sports and clinical science. However, the literature on psoas not sufficiently consistent. Questions are, amongst others, if during hip flexion always has same as iliacus, affects more than lumbar spine. In present study, 17 healthy women, 20–40 years, performed active straight leg raise (ASLR), with right or left ("Side"), without weight added above ankle ("Condition"). Electromyographic (EMG) activity iliacus were recorded fine-wire...
Fracture comminution occurs in 83.9%-94% of vertical femoral neck fractures (VFNFs), the majority which were located posterior-inferior region, and poses a clinical challenge fixation stability. We conducted subject-specific finite element analysis to determine biomechanical features optimal selection for treating VFNF with comminution.Eighteen models three fracture types (VFNF without [NCOM], [COM], + osteoporosis [COMOP]) six internal (alpha [G-ALP], buttress [G-BUT], rhomboid [G-RHO],...
ABSTRACT Numerous studies have reported on in‐vivo posterior femoral condyle translations during various activities of the knee. However, no data has been knee motion a continuous flexion‐extension cycle. Further, few investigated gender variations kinematics. This study quantitatively determined condylar 10 male and female knees weightbearing cycle using two‐dimensional to three‐dimensional fluoroscopic tracking technique. The were CT‐scanned create models tibia femur. Continuous images...
The cumulative error at a point in LiDAR-derived DEM consists of three components: propagated LiDAR-sensor error, ground and interpolation error. To combine these components so as to assess the vertical accuracy DEM, statistical methods based on propagation theory are often used. Due existence systematic only effective if large number checkpoints available, which may not be affordable many practical applications. This paper presents approximation an alternative methodology that departs from...
Vertical femoral neck fractures (VFNFs) are one of the most difficult to stabilize, with high non-union (17%), avascular necrosis (AVN, 21%), and shortening (FNS, 29.0%) rates. The objective this investigation was directly compare long-term clinical complication rates VFNFs repaired by crossed (Alpha fixation) or parallel screws in non-geriatric patients.We conducted a retrospective comparative study patients (<60 years) between January 2014 December 2017, at least 2 years follow-up. were...
As the commonly used fixation strategy of medial malleolar fractures, cancellous screws (CS) have been challenged for instability, bone destruction, and metal prominence. It is still unclear whether a locking compression plate (LCP) better choice in such fractures. Our purpose to compare mechanical efficacy LCP with traditional 4.0-mm CS transverse, oblique, vertical fractures by using finite element analysis. In this study, 3-dimensional models distal tibia were reconstructed from computed...
Abstract Background The treatment of vertical femoral neck fractures (vFNFs) in young patients remains challenging, with a high complication rate by using traditional techniques. use cannulated screws (CSs) combined buttress plate represents an alternative approach for treating vFNFs. However, the biomechanical influence or non-use proximal plates on vFNFs stability unclear. This study aims to analyse biomechanics fixation without through finite element analysis (FEA) further understand this...
Abstract Existing research on DEM vertical accuracy assessment uses mainly statistical methods, in particular variance and RMSE which are both based the error propagation theory statistics. This article demonstrates that is not applicable because critical assumption behind it cannot be satisfied. In fact, non‐random, non‐normal, non‐stationary nature of makes very challenging to apply methods. presents approximation as a new methodology illustrates its application DEMs created by linear...
