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...

This study characterized trunk motor control strategies in subjects with low back pain (LBP) using a goal-directed, unstable sitting task assessing feedforward (motor planning) and feedback control of the lumbopelvic system. Center of pressure (COP)-based outcomes suggested that feedforward strategi...

A complete understanding of the specific sequence of mechanical and biochemical events, especially in a dynamic environment, is lacking. The goal of this study is to measure chondrocytes deformation in situ when dynamic mechanical loads of physiological relevance are applied. The measurement system ...

This study investigated the classification of muscle activation patterns (MAP) during normal walking and while performing a cognitive task using artificial neural networks. The MAPs were successfully classified (average classification rate = 92.2%), indicating a systematic difference between single ...

Immediate mobilization shows neuromuscular benefits, but lengthening of Achilles tendon (AT) could be a devastating problem. Here we describe the AT angle of clinical failure (CF) during cyclical mobilization in human cadaveric specimens that were repaired using the Dresden technique. Eight lower li...

The goal of this study was to assess the differences in collision work performed by healthy, aged-matched controls compared to patients with peripheral artery disease (PAD) to provide foundations for an eventual exoskeleton design.

Most running injury studies have used either purely biomechanical or purely epidemiological methods. Results from biomechanical studies comprise stepwise kinematic and/or kinetic variables,e.g. joint angles and/or moments, while results from epidemiological studies comprise training variables (e.g. ...

Regular papers should present novel perspectives within the general scope of the conference. Short papers (Work-in-Progress) are an opportunity to present preliminary or interim results. Posters are intended for ongoing research projects, concrete realizations, or industrial applications/projects pr...

The aim of this study is to evaluate the influence of aging on the mechanical properties of the supraspinatus tendon, using Supersonic Shearwave Imaging (SSI) elastography. We evaluated 38 healthy individuals of both sexes, being 20 in the range of 20 to 35 years and 17 over 60 years old. The shear ...

Understanding the biomechanics of spiking a volleyball may enable new techniques for prevention and rehabilitation of non-traumatic shoulder injuries particularly in adolescent volleyball players. This study compares shoulder kinematics data collected from high school volleyball players with previou...

With recent developments in the resolution with which spine skin-surface motion is tracked, the opportunity presented itself to calculate dynamic spine stability across smaller sub-regions of the lumbar spine. Additionally, the effect of constraining pelvis motion on dynamic spine stability isn’t ...

With future applications of torso electromyograms (EMG) to control dexterous robotic devices in vision, the static contraction of several torso muscles was characterized during EMG-based target-matching contractions in healthy young adults. The resulting data provided empirical bases upon which indi...

It is of interest for health professionals to automatically classify and diagnose diabetic neuropathy (DPN) patients. Therefore, in this study, we initially propose a machine learning based tool capable of discriminating healthy from DPN individuals using motor data from surface electromyography sig...

Total knee arthroplasty (TKA) candidates are demographically and biomechanically heterogeneous and can be well characterized by four cluster phenotypes related to functional improvement post-TKA. Cluster profiling can support triaging and developing osteoarthritis (OA) treatment and surgical strateg...

Visual feedback has been shown to assist rehabilitation in populations with motor control deficits. This study uses a laser light worn on the lower limb and a target board to provide visual feedback to post-stroke and MS participants. Kinematic and temporal responses were recorded during a box step ...

This study aims to determine the response of stroke survivors to user-driven treadmill control and functional electrical stimulation (FES) of their paretic ankle musculature. 14 stroke survivors walked at their self-selected (SS) and fast speeds on an instrumented treadmill in its fixed speed (FS) m...

Animals easily navigate complex terrain and can rapidly and safely reject unexpected perturbations. However, the underlying mechanism at the muscle-tendon level of this behaviour is unclear. To study this, we attach a real muscle-tendon unit to a novel bio-robotic interface that emulates interaction...

Regular papers should present novel perspectives within the general scope of the conference. Short papers (Work-in-Progress) are an opportunity to present preliminary or interim results. Posters are intended for ongoing research projects, concrete realizations, or industrial applications/projects pr...

Tendon exhibits a hierarchical fibrillar structure, and force transfer across tendon subunits and at different length scales is an integral part of the tissue’s mechanical function. Understanding multiscale mechanisms across distinct tendons may improve therapies to restore degenerate tendon ...

With the growing popularity of the sport of volleyball, there are concerns of lower extremity injuries in front-row players. Different landing mechanics experienced by the three front row positions give insight into possible causes of common injuries of players. Twelve female Division II collegiate ...

Tracking Soldier gait parameters in the field using a non-obtrusive, shin mounted inertial measurement unit (IMU) may provide increased insight into metrics related to performance and/or injury potential relative to lab-based measurements. However, until recently, wearable sensors lacked the appropr...

Higher risk of fracture in individuals with Autism Spectrum Disorder (ASD) may be related to poor bone development in childhood. Prior research indicates that children with ASD have a lower areal bone mineral density (aBMD) but similar aBMD gains during development when compared to typically develop...

Low back pain (LBP) remains a critical issue in primary care. Currently, clinical practitioners rely on subjective measures/questionnaires to categorize LBP patients to pursue specific treatment regimens. However, the need for new objective scales to assess the level of patients’ prognosis risk is...

The combination of model-based tracking techniques with biplane fluoroscopy for quantifying in vivo kinematics of various joints has evolved from initial, novel experimental applications, to more recent applications using clinical biplane fluoroscopy systems. The equipment and expertise needed to pe...

Anterior cruciate ligament reconstruction (ACLR) patients were grouped into four distinct clusters, based on walking vertical ground reaction force (VGRF) traces and knee injury and osteoarthritis outcome subscores (KOOS), using a novel statistical approach. Distinct representative VGRF traces resul...

Impact loading has been linked to the increased risk of tibial stress fracture and plantar fasciitis in runners. This study investigated the combined effects of foot strike pattern, step rate, and anterior trunk lean gait modifications on impact loading. Nineteen healthy runners received real-time b...

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...

Purpose: The purpose of this study was to compare the differences in frequency, and location of head impact events per match between lightweight and heavyweight MMA fighters. Methods: 30 videos of professional MMA bouts were viewed to document all impacts to the head. Independent sample t-tests were...

Previous research has shown that program-based identification was a reliable method to identify lumbar spine vertebrae for epidural procedures. The consistency and temporal efficiency of this program-based identification (PBI) was found to be vastly greater than that of human identification. Likewis...
