Sensitivity of musculoskeletal model-based lumbar spinal loading estimates to type of kinematic input and passive stiffn...
Published in Journal of biomechanics
The study investigated the potential for obtaining more accurate spine joint reaction force (JRF) estimates from musculoskeletal models by incorporating dynamic stereo X-ray imaging (DSX)-based in vivo lumbar vertebral rotational and translational kinematics compared to generic, rhythm (RHY)-based kinematics, while also observing the influence of a...
Ankle and knee moment and power adaptations are elicited through load carriage conditioning in males.
Published in Journal of biomechanics
Soldiers routinely conduct load carriage and physical training to meet occupational requirements. These tasks are physically arduous and are believed to be the primary cause of musculoskeletal injury. Physical training can help mitigate injury risk when specifically designed to address injury mechanisms and meet task demands. This study aimed to as...
Assessment of biomechanical properties of the extracellular and pericellular matrix and their interconnection throughout...
Published in Journal of biomechanics
During osteoarthritis (OA)-triggered cartilage degeneration, the chondrocytes spatially rearrange from single to double strings, and then to small and finally big clusters. Both the extracellular matrix (ECM) and the pericellular matrix (PCM) progressively degrade in osteoarthritis, changing the overall mechanical properties of the cartilage. We in...
The effects of topology and relative density of lattice liners on traumatic brain injury mitigation.
Published in Journal of biomechanics
This paper evaluates the effects of topology and relative density of helmet lattice liners on mitigating Traumatic Brain Injury (TBI). Finite Element (FE) models of new lattice liners with prismatic and tetrahedral topologies were developed. A typical frontal head impact in motorcycle accidents was simulated, and linear and rotational accelerations...
The ability of surface electromyography to represent supraspinatus anterior and posterior partition activity depends on ...
Published in Journal of biomechanics
This study examined relationships between electromyography recorded from indwelling electrodes of the anterior and posterior supraspinatus and a surface supraspinatus electrode. Twenty male and twenty female participants completed full range humeral elevations in three planes of elevation (0/40/90°) and three hand loads (unloaded/20%/40% of maximal...
Mechanical characterization of an in-body tissue-engineered autologous collagenous sheet for application as an aortic va...
Published in Journal of biomechanics
The reconstruction of the aortic valve using glutaraldehyde-treated autologous pericardium is known as "aortic valve neo-cuspidization" (AVNeo). In-body tissue architecture (iBTA), a cell-free, in vivo tissue-engineering technology that can form autologous implantable tissues of the desired shape by subcutaneous embedding specially designed molds, ...
Characterizing the shoe-rung friction requirements during ladder climbing.
Published in Journal of biomechanics
Ladder slip and falls cause negative financial and health impacts due to their severity and frequency. However, frictional requirements of climbing, which presumably influence slip risk, are unknown. The purpose of this study was to quantify frictional requirements during climbing at different ladder angles. The required coefficient of friction (RC...
Biomechanists can revolutionize the STEM pipeline by engaging youth athletes in sports-science based STEM outreach.
Published in Journal of biomechanics
Increasing diversity in the STEM (Science, Technology, Engineering, and Math) fields has become imperative to ensure equitable access to economic opportunity and to provide the technologically adept workforce of the future. The present STEM pipeline preferentially engages youth who are, not only aware of and interested in STEM, but also, can see th...
The effects of upper airway tissue motion on airflow dynamics.
Published in Journal of biomechanics
The human upper airway is not only geometrically complex, but it can also deform dynamically as a result of active muscle contraction and motility during respiration. How the active transformation of the airway geometry affects airflow dynamics during respiration is not well understood despite the importance of this knowledge towards improving curr...
