Vector Analysis of the Vertebral Column in the Frontal Plane – Part 1
https://www.cpduk.co.uk/news/vector-analysis-vertebral-column-frontal-plane-part-1
This contribution explores the biomechanical interpretation of vertebral deviations observed in the frontal plane through a vector-based framework grounded in applied physics. Lateral spinal configurations are examined as three-dimensional mechanical outcomes rather than purely two-dimensional findings.
The article clarifies the relationship between vertebral rotation, lateral translation, and inclination, introducing a causal reading model that differentiates convexity driven by direct muscular traction from concavity arising as a geometric consequence of skeletal convergence. Particular attention is given to the informational differences between standing and supine assessment, highlighting their distinct diagnostic implications.
Segmental analysis focuses on the upper cervical and cervico-thoracic regions, followed by an introduction to the latissimus dorsi as a key generator of complex spinal resultants. Pattern A is described as a predictable mechanical organization emerging from specific lines of force within the latissimus dorsi functional unit.

A Physical Interpretation of Muscle Shortening: When "Weakness" Isn't Weakness

📖 Full article: https://aifimm.it/en/a/biomechanics-causes-muscle-shortening
Dr. Mauro Lastrico, physiotherapist.

This article proposes an interpretation of muscle shortening phenomena based on material mechanics principles.
Starting from the clinical observation that muscles tend to shorten their length, we apply the theory of differential elasticity coefficients to explain how contractile components (high elastic coefficient) and connective components (low elastic coefficient) respond differently to mechanical stress.
The model introduces the fundamental concept of the inversely proportional relationship between Resistive Force (RF) and Work Force (WF), demonstrating how connective component shortening generates mechanical inefficiency rather than true muscle weakness.
The analogy: it's like pushing a cart with the parking brake engaged - the motor works perfectly but energy is dissipated overcoming internal resistance.
Implications include static alterations (joint axis modifications), dynamic changes (increased energy expenditure), and the tendency toward perpetuation through adaptive compensations.
Reversibility is predicted by the same physical laws through application of appropriate forces for times compatible with the tissue's viscoelastic properties.
