Abstract The lunge is regularly used in badminton and recognized for the high physical demands it places on lower limbs. Despite its common occurrence, little information available biomechanics of lunging singles game. A video-based pilot study confirmed relatively frequency lunging, ∼15% all movements, competitive games. performance characteristics three badminton-specific tasks (kick, step-in, hop lunge) were investigated laboratory with nine experienced male players. Ground reaction...
Juvenile idiopathic arthritis (JIA) affects body structure and function physical activity outcomes. The present study was undertaken to examine differences in gait kinematics during fixed-speed treadmill walking for youth with JIA typically developing (TD) youth.Sagittal plane were obtained using a 12-camera system (Motion Analysis) (n = 30) their age sex-matched TD peers 30). Outcomes included disease activity, pain, well-being, peak sagittal hip, knee, ankle joint angles. Kinematics...
High-speed dual fluoroscopy is a noninvasive imaging technology for three-dimensional skeletal kinematics analysis that finds numerous biomechanical applications. Accurate reconstruction of bone translations and rotations from dual-fluoroscopic data requires accurate calibration the geometry many distortions corrupt data. Direct linear transformation methods are commonly applied performing using two-step process suffers number potential shortcomings including each X-ray source corresponding...
BackgroundClinical management of children and youth with cerebral palsy (CP) is increasingly supported by computerized gait analysis.Methods have been developed to reduce the complexity interpreting biomechanical data quantify meaningful movement patterns.However, few methods are inclusive multiple joints planes motion, consider entire duration phases; potentially limiting insight into this heterogeneous pathology.The objective study was assess implementation k-means clustering determine...
Small-size, light-weight, flexible and programmable, yet low-cost sensor node is one of the keys to enable Wireless Sensor Network (WSN) research a wide range user applications. In this paper, Bracelet computer presented. The system designed be wearable that it supports daughter boards user's choice, provides different ways for connected main processor board. Despite features, monetary cost kept low. An application - which uses same wireless board as localising running athlete presented in...
Juvenile idiopathic arthritis (JIA) is associated with altered body structure and function outcomes that may expose youth JIA to a greater risk of secondary joint injury. This study aimed examine differences in vertical drop jump (VDJ) biomechanics for healthy (control group).The present was matched pair cohort study. Youth (n = 30) their age- sex-matched control peers participated this ethics-approved Lower-extremity information obtained using motion analysis system (Motion Analysis) 2...
The levitation tricompartment offloader (TCO) brace is designed to unload all three knee compartments by reducing compressive forces caused muscle contraction. This study aimed determine the effect of TCO on contact and quadriceps activity in individuals with osteoarthritis. Lower limb kinematics, kinetics, electromyography data were collected during a chair rise-and-lower task. A three-dimensional inverse dynamics model lower leg foot was used sagittal plane compute joint forces. use...
In this cross-sectional study, we compared patellofemoral geometry in individuals with a youth-sport-related intra-articular knee injury to uninjured individuals, and the association between magnetic resonance imaging (MRI)-defined osteoarthritis (OA) features. Youth Prevention of Early OA (PrE-OA) cohort, assessed 10 measures 3-10 years following similar age, sex, sport, using mixed effects linear regression. We also dichotomized identify extreme (>1.96 standard deviations) features...
Accurate speed and split-time information on sprinters is crucial in coaching support. Furthermore, stride parameters (i.e. contact time, frequency, length) are important research the biomechanics of running. Existing speed-tracking systems for sprinting expensive, unable to support multiple competing athletes, involve a complicated set-up procedure, or not sufficiently accurate. This paper describes design, evaluation results, application scenarios novel, practical, cost-effective...
Accurate quantification of bone and cartilage features is the key to efficient management knee osteoarthritis (OA). Bone tissues can be accurately segmented from magnetic resonance imaging (MRI) data using supervised Deep Learning (DL) methods. DL training commonly conducted large datasets with expert-labeled annotations. models perform better if distributions testing (target domains) are close those (source domains). However, in practice, images different MRI scanners sequences need...
Total knee arthroplasty (TKA) patients commonly experience neuromuscular adaptations that may affect stair climbing competence. This study identified multimuscle pattern (MMP) changes in postoperative female TKA during with a support vector machine (SVM). It was hypothesized adopt temporal and spectral muscle activation characteristics indicative of atrophy cocontraction strategies. Nineteen subjects [10 unilateral sex-specific TKAs, 62.2 ± 8.6 yr, body mass index (BMI) 28.2 5.4 kg/m(2); 9...
Abstract Background Cervical spine manipulation (CSM) is a frequently used treatment for neck pain. Despite its demonstrated efficacy, concerns regarding the potential of stretch damage to vertebral arteries (VA) during CSM remain. The purpose this study was quantify angular displacements head relative sternum and associated VA length changes thrust phase CSM. Methods Rotation lateral flexion procedures were delivered bilaterally from C1 C7 three male cadaveric donors (Jan 2016–Dec 2019)....
Stride-related parameters of sprinters, such as split times (i.e. which is speed-related), foot contact times, stance stride/step length, and frequency, etc. are important factors affect athletes' performances. Traditionally, this information captured by biomechanics researchers coaches using optical-based systems. However, these systems expensive, time consuming to setup, have limited viewing angles. Thus, existing research work on sprinting small scale short studies. This paper presents a...
