The purpose of the study was to verify the specificity of the proximal-distal sequence of the jump throw in handball. This phenomenon was observed from three different perspectives: (1) the sequence of the maximal linear velocities of the joints and ball, (2) the sequence of the initiation of the mo...
Characterisation of tendon mechanical properties is of importance to gain a comprehensive understanding of this tissue’s responses to ageing and loading and can also inform the development of artificial biomaterials based on living tissue data. In this study, we presented an innovative method of c...
In this study, a novel method for in vivo finger motion measurement was proposed. A six degree of freedom electromagnetic tracking system was used to prevent line of sight constraints. A novel landmark digitization method was used that provided accessible landmarks for in vivo use. The study involve...
In this validation study we investigated the L5/S1 moment estimation performance of an ambulatory measurement system: inertial measurement suit (Xsens) and instrumented force shoes. A top-down (starting at hands) and a bottom-up (starting at feet) inverse dynamic approach were tested. As a reference...
A comparative computational probabilistic analysis assessed influences of evolutionarily important musculoskeletal features on rotator cuff function for human and chimpanzee glenohumeral joints. Species-specific distinctions emphasized differences in primary shoulder function and provide novel conte...
A causal relationship between pain and gait alterations in knee osteoarthritis (OA) is often implied in the cross sectional studies, however evidence of a casual relationship between pain and gait mechanics in the literature is limited. We have explored the motor system response to acute exacerbatio...
The purpose of this study was to quantify the effects of using geared wheels on hand-rim kinetics and glenohumeral joint kinetics during wheelchair ramp ascent in individuals with spinal cord injury (SCI). Seven veterans with SCI propelled their manual wheelchairs equipped with geared wheels up a ra...
Elliptical chainrings have been designed to manipulate the radius as a function of crank angle, consequently altering the crank angular velocity profile experienced through the pedal cycle. We tested chainrings with varying levels of eccentricity and crank orientations to drive a musculoskeletal mod...
After an incomplete spinal cord injury (iSCI), gait deficits of different severities are present and depending on affected tracts, compensatory strategies are often applied. The purpose of this study was to quantify gait impairments and effects of compensatory strategies in individuals with iSCI usi...
There is a well-established relationship between anterior cruciate ligament reconstruction (ACLR) and the premature development of osteoarthritis (OA) [1]. Transverse relaxation (T2) time, a quantitative magnetic resonance imaging (qMRI) parameter, is capable of quantifying the degradation of the ca...
This study demonstrates a biofeedback method for training adaptable gait. The method involved a customised program and 3D motion capture system. 22 young adults were selected to test the effect of gait adaptability training of two target-oriented stepping tests while walking: (1) vertical foot heigh...
A system to generate mechanical load to the musculoskeletal system, through neuromuscular electrical stimulation (NMES), was developed, with load control through an isometric dynamometer adapted for bed-rest situations. The system allows for the control of several NMES parameters, and positions the ...
Current researches related to patient-specific knee prosthesis designs are mainly mimicked the anatomical structure of femoral condyle, but the kinematics and the long-term performance are still questionable. What’s more, since the end-stage knee osteoarthritis patients are usually associated with...
Definition of reference frames for the bones articulating at the ankle joint, that can be identified with high accuracy and repeatability, is essential for many biomechanical and clinical applications. Marker-inspired reference frames, representing the majority of exiting reference frame systems pro...
When computing ankle joint complex power using inverse dynamics, should you cut holes in the shoes to allow for skin-mounted motion tracking markers? And how important is consistency in marker location on the foot? We addressed these two important questions in walking and running. Our results sugges...
This study examines the biomechanical and patient reported outcomes for patients using an Intrepid Dynamic Exoskeletal Orthosis (IDEO) whom are one year post rehabilitation. It is unknown how well these devices are being used and how these patients feel they are doing compared to other patients who ...
Many athletes who perform jumping movements in their sport wear a prophylactic ankle brace as an injury preventative measure. However, it has been theorized that stabilization at the ankle joint may cause excessive frontal plane knee angle and moment in females. Limited research has examined the fro...
The study was investigated the relationship between changes in the performance of vertical jumps and punch velocity in karate. Variations in relative force (RF) and vertical impulse (VI) are the associated the velocity peak of fist (VPF). Therefore, there is a high contribution the lower body muscle...
Heterogenous strain distribution within the Achilles tendon has been regarded as a main contributor of the overuse injuries and tendinopathy. Yet it is not possible to measure internal tissue stress/strain distribution in real time due to technical and computational difficulties. We present here a m...
Traumatic brachial plexus injuries (BPI) are debilitating and result in lifelong upper extremity dysfunction. Surgical restoration of motor function relies on salvageable nerves and muscles for transfer procedures. Kinematic data from subjects after a brachial plexus reconstruction was analysed duri...
Machine learning was applied to whole-body kinematics collected during a standardized lifting task to predict lifting start and end height and weight lifted. The resulting models included features of the forearm and pelvis segments, and resulted in accurate classification rates between 83% and 98%.
A novel method for accurately measuring carpal kinematics in a cadaveric model was developed via discreet sensors rigidly fixed to carpal bones using single attachment mounts.
Despite the growing amount of literature suggesting a greater reliance on visual information and cognitive processing following an anterior cruciate ligament reconstruction (ACLR), no known study has investigated the interplay between cognition and visual feedback in an ACLR population. The purpose ...
This study examined the changes in the smoothness of joint torques during therapeutic interventions to sit-to-stand (STS) movement performed by the subjects after stroke. The results showed two expert physiotherapists consistently handled the motions to adjust the smoothness. The effect was observed...
Material slippage forms a major issue in the biomechanical testing of soft tissues. We here present a clamping technique utilizing 3D printing technology which allows to test soft tissues in a highly standardized and high throughput manner. Results from image correlation and scanning electron micros...
Posterior tibialis tendon dysfunction (PTTD) is the principal cause of adult acquired flatfoot. As PTTD is related to the eversion of the rear foot, it is important to know if foot orthoses can attenuate this movement during gait. Results of this study show that custom foot orthoses (FOs) reduced ev...
Understanding the cartilage micro-environment has significant implications for evaluation of mechanobiological function of diarthrodial joints. The goal of this study was to measure the 2D strains through the cartilage thickness when dynamic mechanical loads of physiological relevance are applied. A...
The purpose of the study was to investigate the effect of mechanical loading on serum biomarker concentrations of articular cartilage in relation to knee joint mechanics. Thirty minutes of moderate running exercise caused an increase in all analyzed serum biomarker concentrations. However, no direct...
Gait analysis is essential in orthotics and prosthetics (O&P) practice. This pilot study aimed to determine the reliability of a simple 2D video-software analysis tool and to compare it with 3D gait laboratory. Gait trials were undertaken with 10 able-bodied participants. The 2D video-software syste...
