The primary role of muscles is to move, and control joints. It therefore important understand how degenerative joint disease changes this with the resulting effect on mechanical loading. Muscular strategies can vary depending strength coordination which in turn influences purpose study was investigate variation neuromuscular mechanisms biomechanics for three subject groups including those with: uni-compartmental knee osteoarthritis (OA), listed high tibial osteotomy surgery (pre-HTO, n =...
The mechanical properties of the skin are important in many applications, but not well understood. This paper presents a method for measuring human vivo using digital image correlation, with finite element model that was used to optimize material obtain best match data. modelled as an Ogden hyperelastic membrane, tension field wrinkling and initial stretch identified additional parameter, boundary conditions were measured load displacements around edge region interest. Fast, reliable...
The dart thrower’s motion is a wrist rotation along an oblique plane from radial extension to ulnar flexion. We report in-vivo study confirm the use of during activities daily living. Global in ten volunteers was recorded using three-dimensional optoelectronic capture system, which digital infra-red cameras track movement retro-reflective marker clusters. has been approximated when hammering nail, throwing ball, drinking glass, pouring jug and twisting lid jar, but not combing hair or...
The aim of this study was to examine the loading other joints lower limb in patients with unilateral osteoarthritis (OA) knee. We recruited 20 no symptoms or deformity limbs from a consecutive cohort awaiting knee replacement. Gait analysis and electromyographic recordings were performed determine moments at both knees hips, contraction patterns medial lateral quadriceps hamstrings bilaterally. speed gait reduced group OA compared controls, but there only minor differences stance times...
There are few guidelines for clinical trials of interventions prevention post-traumatic osteoarthritis (PTOA), reflecting challenges in this area. An international multi-disciplinary expert group including patients was convened to generate points consider the design and conduct interventional studies following acute knee injury.An evidence review on injury prevent PTOA presented group, alongside overviews area, potential targets, biomarkers imaging. Working groups considered pre-identified...
The accuracy of partial weightbearing was assessed in six healthy volunteers and 23 patients who had sustained either a fracture lower limb or surgery. They were trained to weightbear partially using the conventional bathroom scale method gait laboratory force platforms. amount weight exerted on involved during three-point crutch walking determined. Four mean 27% body more than required. remaining two 8.5% less Of patients, 21 35.3% that prescribed 11.97% prescribed. In both groups there...
Background Gait analysis can be used to measure variations in joint function patients with knee osteoarthritis (OA), and is useful when observing longitudinal biomechanical changes following Total Knee Replacement (TKR) surgery. The Cardiff Classifier an objective classification tool applied previously examine the extent of recovery TKR. In this study, it further developed reveal salient features that contribute towards healthy function. Methods was performed on 30 before after TKR surgery,...
Skin deformation behaviour is complex, that exhibits similarly to an anisotropic, non-homogenous and viscoelastic material. Nevertheless, the understanding of skin characteristics important in many applications. This study attempts investigate simulate under tensile loading using integration experimental-computational approaches. An experimental procedure has been conducted measure motion capture system. Based on information data obtained from measurement, finite element models are developed...
This study aims to examine alternative methods of normalization that effectively reflect muscle activity as compared Maximal Voluntary Contraction (MVC). EMG data recorded from knee flexion-extension muscles in 10 control subjects during the stance phase gait cycle were examined by adopting different approaches normalization: MVC, Mean and Peak Dynamic cycles, (MDM PDM, respectively), activities daily living (ADLs), (*PDM), a combination ADLs MVC(**PDM). Intra- inter-individual variability...
Quantitative assessment of movement impairment in Huntington's disease (HD) is essential to monitoring progression. This paper aimed develop and validate a novel low cost, objective automated system for the evaluation upper limb HD order eliminate inconsistency assessor offer more sensitive, continuous scale. Patients with genetically confirmed healthy controls were recruited this observational study. Demographic data, including age (years), gender, unified rating scale total motor score...
The purpose of this study was to quantify changes in knee loading the three clinical planes, compensatory gait adaptations and patient-reported outcome measures (PROMS) resulting from opening wedge high tibial osteotomy (HTO).Gait analysis performed on 18 participants (19 knees) with medial osteoarthritis (OA) varus alignment pre- post-HTO, along controls, calculate temporal, kinematic kinetic measures. Oxford Knee Score, Outcome Survey visual analogue pain scores were collected. Paired...
Despite the high number of total hip arthroplasty (THA) procedures performed each year, there is no common consensus on best surgical approach. Gait known to improve following THA although it does not return what typically quantified as normal, and approach believed be a contributing factor. The current study evaluates postoperative function provides an objective assessment two approaches: McFarland-Osborne direct lateral southern posterior. Faced with problem providing comparison from...
In this paper, a novel object classification method is introduced and developed within biomechanical study of human knee function in which subjects are classified to one two groups: with osteoarthritic (OA) normal (NL) function. Knee-function characteristics collected using three-dimensional motion-analysis technique. The transforms these into sets three belief values: level that subject has OA function, NL an associated uncertainty. evidence from each characteristic then combined final set...
Huntington's disease (HD) is a progressive inherited neurodegenerative disorder, causing involuntary movement and cognitive problems, severely affecting the quality of life. Controlling upper limb function core feature daily activity can prove problematic for people with HD. The Money Box Test (MBT) has been developed purpose quantifying frequently seen in In this research, wearable highly sensitive accelerometers are used to collect acceleration hands chest during performance MBT.
