Article Title: In-silico neuro-musculoskeletal model demonstrates spasticity progression with descending motor tracts loss in simulated clinical triage.
Article Snippet: Our study explores the complex mechanisms of spasticity using a multi-scale neuro-musculoskeletal model to investigate its emergence and characteristics following spinal cord injury.. We built a large-scale, biologically realistic, closed-loop spino-musculoskeletal model of the lower limb using the NEUROiD co-simulation platform.. The in-silico spinal cord incorporated around 50 spinal pathways, 40,000 alpha motor neurons, and approximately 12 million interconnections spanning L2-S2 and was simulated on NEURON.

Article Title: The Effect of swivel chairs on lumbar health in individuals with TFCLs sitting Habits: An analysis of lumbar disc Mechanical characteristics during Postural changes.
Article Snippet: The comfort of a chair should be assessed based on the alignment between the chair’s features and the user’s behavioral characteristics.. Considering modern habits and types of seating, prolonged work often leads to frequent shifts from correct posture (Torso Upright with Parallel Legs) to poor posture (Torso Flexion with Crossed Legs).. Thus, exploring how to select an appropriate chair type to accommodate these frequent transitions between TUPLs and TFCLs becomes a topic worthy of thorough investigation.
