We investigated the effects of obesity on musculoskeletal pain at various regions of the upper torso, and shoulder range of motion (RoM) in community-based women. Obese women displayed increased musculoskeletal pain in the shoulders and arms, as well decreased shoulder RoM compared to their leaner c...
Knee valgus angles and moments during unanticipated motions have been previously identified as factors of anterior cruciate ligament injury (ACL). Prophylactic knee braces are knee braces that are designed to mitigate this and reduce the risk of injury. To determine the effectiveness of these braces...
[Purpose] The purpose of this study was to investigate the effect of Rocker Sole (RS) with Pivot Point (PP) on the metatarsal head (MTH) on lower extremity joint angle during gait. [Methods] Ten healthy men underwent three-dimensional gait analysis while walking wearing RS and postoperative shoes (P...
The leg-dominance theory suggests that kinetic and kinematic asymmetries place athletes, particularly females, at a higher risk of non-contact anterior cruciate ligament (ACL) injuries. Sex and age effects on asymmetry of sagittal plane lower extremity joint angles and moments during the stance phas...
The purpose of this study was to investigate what the effect is of prioritizing kicking velocity or accuracy upon kinematics and kicking performance in soccer. 13 male soccer players performed penalty-kicks with prioritising velocity or accuracy. 3D kinematics, together with maximal ball velocity an...
The aim of this study was to investigate the effect of Kinesio taping (KT) on female college students by fatigue intervention, on stop-jump task. Eleven female athletes served as subject. Two force plates and ten cameras were synchronized to capture the stop-jump task. The kinematics results found t...
Anatomically accurate reconstruction of joint structures, including bone and cartilage, is necessary in musculo-skeletal modelling and prosthesis designs. Correspondingly, CT and MRI shall be used, possibly in combination. A single ankle specimen was analyzed by producing 3D bone and cartilage model...
Arterial wall motion was analysed in the atherosclerotic plaque models to study the effect of wall tissue viscoelasticity and lipid core stiffness on wall displacement waveforms. A typical slice of the patient’s IVUS data was modelled, and the anisotropic and viscoelastic behaviour of tissue was c...
The medial longitudinal arch (MLA) plays a major role in transferring forces through the foot and to the body. Foot exercises can help the MLA structure in different moments of the stance phase.
Quadriceps muscular strength weakness is commonly observed in individuals following ACL injury (ACLI). However, it is inconclusive whether force steadiness is worse in ACLI individuals. Twenty-four subjects with ACLI (54.9 days prior to testing) and 25 control subjects (CONTROL) completed the maxima...
The purpose of this study was to analyze the effect of potential fallers on fall analysis. 79 elderly people aged 60 years or older were participated in this experiment. Subjects were divided into four groups (GROUP1: non-faller - non-faller n = 46, GROUP2: non-faller - faller n = 12, GROUP3: faller...
Kinematic and electromyography data were collected from people without transtibial amputation (TTA) and with TTA for three prosthetic alignment conditions during sit-to-stand (STS). People with TTA had greater amputated side and lower intact side rectus femoris activity compared to people without TT...
In reverse shoulder arthroplasty (RSA), controversy exists over whether to repair the subscapularis and infraspinatus muscles. The objectives of this study were to investigate the effect of rotator cuff deficiencies and repairs on deltoid force in RSA and assess for any interaction with humeral impl...
We have conducted experimental study (n=1) to investigate the effect of different shoes on foot bone kinematics. Kinematics were acquired using fluoroscopy while 3D geometry of the foot was recorded with a CT. The participant had to move from a one-legged stance into a tip-toe stance. Afterwards the...
Previous models of articular cartilage permeability were successful in demonstrating the effect of the collagen fibres on the anisotropy of the permeability, but could not reproduce some experimental results under large deformations. The proposed model, which accounts not only for fibre reorientatio...
The purpose of this research is to evaluate the influence of surface condition of culture substrate on cell adhesion, cell activity and cell differentiation. It is well known that photofunctionalization on surfaces promotes the osteogenesis. It is common knowledge that cells strongly adhere to UV ir...
In this study, a simple bipedal model with an upper body walks down on a gentle moving slope to clarify the effect of trunk swinging behaviors on gait on a moving slope via numerical simulation. Gaits with three types of trunk swinging behaviors, forward swinging (FS), backward swinging (BS), and no...
The purpose of this study was to examine relationship between kinetics and effectiveness of mechanical energy utilization during lifting phase of squat. Ten male students majoring physical education. Participants completed one repetition of a high-bar back squat using 75% of 1RM. Sagittal plane kine...
High impact forces are a risk factor for injuries in jump-landing tasks. Strategies to reduce impact during training may help to protect against these risks. Here we describe the impact forces experienced during landing tasks using a model of rebound shoe commercially available. We found that the sh...
Patellofemoral (PF) pain is a common running injury where PF joint stress has been implicated. Using a musculoskeletal model, we examined how PF joint stress is influenced in running with and without 9 kg of added load at a set running speed. PF joint stress increased 10% which was attributed to a 1...
The complex loading that occurs at the residual limb- prosthetic socket interface of a person with an amputation can affect comfort and skin integrity [1]. This study assessed the effect of providing interface pressure measurements to clinicians during the design and fabrication of prosthetic socket...
Robotic assistance in rehabilitation is becoming more and more popular. However, little is known about how the robot's support affects the muscular activation underlying the therapeutic exercise. To investigate the effect of robotic assistance on muscular activation 20 healthy subjects performed the...
Patellofemoral pain syndrome (PFPS) is a common complication in female runners related to patellofemoral joint stress (PFJS). Increases in stride length alone may intensify PFJS, while increasing cadence alone may lower it. Running velocity is the product of stride length and cadence. Our purpose wa...
This study examined the effect of abductor muscle strengthening on joint loading in patients with developmental dysplasia of the hip (DDH). Abductor strengthening reduced peak hip joint reaction force (JRF) by a maximum of 205.2 N (33.7% body weight), yet also increased anterior hip JRF.
Effect of surface profile of a Co-28Cr-6Mo alloy (ASTM F-75) disc on wear behavior of an ultra-high-molecular-weight polyethylene (GUR1050) pin was investigated by using a pin-on-disc wear testing machine with multi-directional pathways. The surface of a Co-28Cr-6Mo alloy disc had a waviness curve f...
We developed and used a “falling dummy” to explore how¶ backward fall dynamics affect head impact severity. We¶ varied torso shape and hip stiffness, based on observations¶ from video-captured real-life falls in older adults. Peak linear¶ and angular head accelerations were higher with rotat...
This study examined the effect of varying step frequency on joint moments during walking and running in four healthy young runners using an instrumented three-dimensional (3D) gait analysis. Overall, the results suggest that faster step frequencies, as adopted by older individuals, result in greater...
A 12-week gait retraining program reduced muscle activities of the TA, LG, and MG under certain conditions, regardless of shoes. These findings may indicate that reduced muscle activity caused by or related to gait retraining presumably have an influence on energy consumption, which may further impr...
This pilot study investigated the impacts of a whole-body, powered exoskeleton on low-back muscle activation and joint ranges-of-motion (ROM) in a load carriage task performed by able-bodied individuals. The prototype exoskeleton (Guardian XOTM, Sarcos Robotics) had 16 active degrees of freedom. Aft...
We examined effects of two murine models of altered loading on postnatal muscle development in the glenohumeral joint. Forearm amputation via elbow disarticulation resulted in decreased muscle mass and optimal length, consistent with previous altered hindlimb loading models.
