The standard Plug-in-Gait (PiG) protocol used in three-dimensional gait analysis is prone to errors arising from inconsistent anatomical landmark identification and knee axis malalignment. purpose of this study was estimate the reliability accuracy a custom made lower body (MA) compared with PiG protocol. Twenty-fve subjects volunteered evaluate intertrial reliability. In addition, intersession examined 10 participants. An indirect indicator according varus/valgus flexion/extension range...

Abstract Compressive knee joint contact force during walking is thought to be related initiation and progression of osteoarthritis. However, loading often evaluated with surrogate measures, like the external adduction moment, due complexity computing forces. Statistical models have shown promising correlations between medial forces moments in particularly individuals osteoarthritis or after total replacements ( R 2 = 0.44–0.60). The purpose this study was evaluate how accurately model-based...

The effects of manipulated dental occlusion on body posture has been investigated quite often and discussed controversially in the literature. Far less attention paid to influence position human movement. If movement was analysed, it mostly while walking not running. This study therefore designed identify effect lower jaw positions running behaviour according different positions.Twenty healthy young recreational runners (mean age = 33.9±5.8 years) participated this study. Kinematic data were...

Compared with walking (W), Nordic (NW) exhibits greater cardiopulmonary and cardiovascular benefits. Some authors conjecture that compared W or running (R), NW imposes smaller mechanical loads on the musculoskeletal system. The purpose of current study was to quantify any differences in joint loading lower extremities among NW, W, R. Fifteen experienced adults participated. Kinematic force measurements were combined using an inverse dynamics approach yield moments. results showed no...

In order to reduce pain caused by the affected hip joint, unilateral osteoarthritis patients (HOAP) adopt characteristic gait patterns. However, it is unknown if knee and joint loading in non-affected (limbnon-affected) (limbaffected) limb differ from healthy controls (HC) which parameters correlate with potential abnormal loading. Instrumented 3D-gait analysis was performed on 18 HOAP sex, age, height matched HC. The limbnon-affected showed greater first second peak external adduction...

Malalignments of the lower extremity are common reasons for orthopedic consultation because it may lead to osteoarthritis in adulthood. An accurate and reliable radiological assessment limb alignment children adolescents is essential clinical decision-making on treatment deformities regular control after a surgical intervention.First, does analysis full-length standing anteroposterior radiographs show good intra- interobserver reliability? Second, which parameter most susceptible...

ABSTRACT A total hip replacement (THR) is a common and routine procedure to reduce pain restore normal activity. Gait analysis can provide insights into functional characteristics dynamic joint loading situation not identifiable by clinical examination or static radiographic measures. The present prospective longitudinal study tested whether 2 years after surgery THR would of the knee joints in frontal plane normal. Instrumented gait was performed shortly before approximately on 15...

Despite good clinical functional outcome, deficits in gait biomechanics exist 2 years after total hip replacement surgery. The aims of this research were (1) to group patients showing similar adaptations osteoarthritis and (2) investigate the effect surgical treatment on kinematics external joint moments. In a secondary analysis, data 51 with unilateral analyzed. A k-means cluster analysis was performed scores derived via principal component kinematics. Preoperative postoperative datasets...

The correction of valgus leg malalignment in children using implant-mediated growth guidance is widely used and effective. Despite the minimal invasive character procedure, a relevant number patients sustain prolonged pain limited mobility after temporary hemiepiphysiodesis. Our aim was to investigate implant-associated risk factors (such as implant position screw angulation), surgical- or anesthesia-related type anesthesia, use, duration), pressure tourniquet duration surgery for these...

Introduction: Correction of knee malalignment by guided growth using a tension-band plate is common therapy to prevent osteoarthritis among other things. This approach based on the Hueter-Volkmann law stating that length bones inhibited compression and stimulated tension. How locally varying mechanical loading influenced implant has not yet been investigated. study combines load cases from gait cycle with personalized geometry in order investigate influence plates. Methods: Personalized...

This investigation prospectively compared self-assessed quality of life and biomechanical measures physical function before after spinal fusion surgery in 26 adult patients with symptomatic lumbar degenerative disease.The objective was to demonstrate that (1) due a reduction low back pain, as well gait parameters would improve (2) performance is more similar observed healthy controls at the same age, whereas trunk range motion remains unchanged surgery.Current outcome evaluations are based...

Patients with unilateral hip osteoarthritis show a characteristic gait pattern in which they unload the affected leg and overload unaffected leg. Information on characteristics of patients bilateral is very limited. The main purposes this study were to investigate whether both legs deviates from healthy controls more symmetrical joint load compared patients. In prospective study, 26 osteoarthritis, included. three groups matched for gender, age walking speed. scheduled total arthroplasty...

Gait kinematics after total hip replacement only partly explain the differences in joint moments frontal plane between osteoarthritis patients and healthy controls. The goal of this study was to determine if surgery affects radiological leg alignment (Hip-Knee-Shaft-Angle, femoral offset, Neck-Shaft-Angle varus/valgus alignment) which these parameters can moments, additionally gait kinematics.22 unilateral who were scheduled for included study. Preoperatively 1 year postoperatively all had...
