Unsupervised Machine Learning Identifies Shared Biomechanical and Clinical Variation in Individuals with Knee Osteoarthritis and High BMI: A Secondary Analysis of the IDEA Trial

Arthritis Care &Research, Accepted Article.
Objective High body mass index (BMI≥27 kg/m2) and aberrant gait biomechanics are primary risk factors for knee osteoarthritis (KOA), yet the specific loading patterns linked to clinical disease features remain unclear. Unsupervised machine learning (ML) was used to identify vertical ground reaction force (vGRF) waveform modes of variation and ...

Multistage, Self‐Sensing Artificial Muscles With Coordination From Liquid Crystal Elastomer‐Graphene Composite Fibers

Advanced Functional Materials, EarlyView.
Inspired by skeletal muscles’ precision and endurance, CoilLCE integrates a self‐sensing liquid crystal elastomer/graphene artificial muscle with an embedded Joule‐heating copper coil, enabling closed‐loop multistage actuation with programmable intermediate states (strain accuracy of 2%), and antagonistic coordination (32% total strain). These features

Improving Gait Balance of the Blind During Robot-Assisted Guidance by Providing Static External Reference

IEEE Access
The gait of blind individuals is characterized by reduced gait stability and postural balance due to their limited sensory information. However, existing systems focus on guidance capability rather than improving gait stability and postural balance ...

The Relationship Between Postural Balance, Posture and Postural Awareness in Patients Diagnosed with Osteoporosis

Türk Osteoporoz Dergisi
Objective: Osteoporosis, characterized by low bone mass and microarchitectural deterioration, leads to increased fracture risk. Beyond skeletal fragility, it is associated with postural deformities, balance impairments, and potentially diminished ...

Falls efficacy, postural balance, and risk for falls in older adults with falls-related emergency department visits: prospective cohort study

BMC Geriatrics, 2017
Background Risk for falls in older adults has been associated with falls efficacy (self-perceived confidence in performing daily physical activities) and postural balance, but available evidence is limited and mixed.
