This study uses inertial sensors to analyze foot clearance and its relation to two gait conditions (walking and running) while traveling on stairs (ascent and descent). Our study found that during stair ascent, clearance is significantly larger when running. This finding suggests that humans use the...

Toe deformities and dysfunction of the tibialis posterior muscle is common among patients with rheumatoid arthritis. The aim of this study was to investigate potential muscle compensation patterns when the tibialis posterior muscle starts to be less active. Results of the study show that flexor digi...

The purpose of this study was to use Continuous Relative Phase (CRP) and CRP variability (CRPvar) to characterize coordination patterns in trunk, lumbar and pelvic regions in runners with a history of resolved LBP vs healthy controls (HC). While previous studies have looked at a resolved LBP in runn...

Running Specific Prostheses (RSP) used by amputee athletes for sprinting and long jumping have a large effect on athlete performance and health. This study reports about the development and test of a set of instrumented RSP (iRSP) that could be used on the field for data collection of block start, s...

This study compared video-based joint angle and reach envelope measures for simulated working tasks to motion capture and to physical demands description estimates from novice and experienced ergonomists. Video-based measures showed low RMS error and high weighted Cohen’s kappa scores, and demonst...

The relationship of midline frontal theta (MFT) and balance control was measured during standing tasks using electroencephalography and inertial sensors.

This study examined the effects of osteoarthritis of the trailing knee on golf performance and rotational kinematics during a golf swing. The study showed that osteoarthritis may cause reduced trunk and knee joint rotations in addition to slower knee rotation velocities, which consequently may cause...

In this case study, we sought to determine whether undesired muscle coactivation limits the upper limb workspace, and whether the coactivation varies with stroke severity. During a voluntary reaching task with different supporting forces on upper limb, changes in muscle activation levels were record...

Walking deficits are common following stroke, yet typically used clinical and functional assessments fail to adequately identify their source. We previously developed a Comprehensive Locomotion Index (CLI) that uses objective measurements and differentiates functional status among individuals with c...

Active workstation use has been shown to decrease sedentary behavior in the workplace. However, a dual-task environment creates a division of focus increasing the risk of an adverse gait-related event. The current study examined lower extremity (LE) tripping descriptors during a difficult precision ...

Falling of the elderly has become an important issue in today's aging society. The key task to prevent falling is the exact detection of a falling event in Activities of Daily Living (ADL). However, certain ADL situations are difficult to classify due to motion and acceleration values of the fall si...

Erroneous conclusions about game effects may be made when game simulations or laboratory-based fatigue protocols are used, due to the task-dependent effects of fatigue. This study was the first to investigate how playing an elite U20s basketball game alters trunk control during an anticipated cut ta...

This paper discusses challenges and opportunities for biomechanics researchers who are integrating wearable sensor data with biomechanical modelling or machine learning approaches in the context of understanding injury mechanisms. Example applications include a framework for integrating body worn in...

In this paper it is presented a simplified cost function (CF) that can be used to determine the pedaling cadence that minimizes the muscular stress in cycling. With respect to similar CF, the proposed one requires less experimental data to be calculated, thus it can be preferable in the characteriza...

In scientific studies and in commercial wearable devices it is often assumed that increases in ground reaction forces (GRF), or in GRF-correlated signals from pressure-sensing insoles and inertial measurement units (IMUs), indicates increases in musculoskeletal loading or overuse injury risk (e.g., ...
