Portable measurement systems using inertial sensors enable motion capture outside the lab, facilitating longitudinal and large-scale studies in natural environments. However, estimating 3D kinematics and kinetics from inertial data for a comprehensive biomechanical movement analysis is still challenging. Machine learning models or stepwise approaches performing Kalman filtering, inverse kinematics, and inverse dynamics can lead to inconsistencies between kinematics and kinetics. We investigated the reconstruction of 3D kinematics and kinetics of arbitrary running motions from inertial sensor data using optimal control simulations of full-body musculoskeletal models...

INTRODUCTION: Thoracolumbosacral orthosis (TLSO) is the most commonly used type of brace for the conservative treatment of adolescent idiopathic scoliosis (AIS). Although lumbosacral orthosis (LSO) is designed to correct single thoracolumbar or lumbar (TL/L) curves, its effectiveness remains underexplored. This novel article aims to compare the effectiveness of LSO with TLSO in treating AIS with main TL/L curves. METHODS: This prospective controlled cohort study enrolled patients with AIS with main TL/L curves and minor thoracic curves who were treated with either TLSO or LSO...

BACKGROUND: Traditional health practitioners (THPs) understand spirit possession as a cultural or religious spirit occupying a person, while the mental healthcare providers understand it as a mental illness. The different understanding is based on manifestations that mimic that of mental illness, such as seeing and hearing things that others cannot see or hear. Spirit possession holds different meanings in different cultures and religions that could be either beneficial or detrimental...

Shockwave-induced changes in nanobubbles cause cavitation erosion and membrane damage but can also be applied to biocarrier transport. Currently, research focuses on single nanobubbles; however, in reality, nanobubbles usually appear as a multibubble system. Therefore, this study proposes a method based on cutting and replicating to construct a multibubble model. This method can be widely applied to molecular dynamics (MD) models and enhance the customization capabilities of MD models. The dynamic behavior of a multinanobubble system with different numbers and arrangements of nanobubbles is investigated with the MD method under the influence of shock waves in a liquid argon system...

BACKGROUND: Black men have among the lowest life expectancy in the United States. Alarmingly, these men are underrepresented in health promotion efforts. There are well-documented barriers to recruiting and retaining Black men in health promotion efforts, such as exclusionary research practices - many researchers may be hesitant to reach Black men in culturally unique spaces, such as barbershops. Despite these practices, qualitative research among Black men unanimously find that Black men are interested in health promotion efforts...
