Musculoskeletal biomechanics: articles, publications, and clinical model
Mauro Lastrico, PT — Laura Manni, PT
The AIFIMM biomechanical model is an analytical and systemic clinical framework for interpreting pain, dysfunction, and joint and spinal pathologies. This page collects scientific articles, theoretical foundations, clinical applications, downloadable PDFs, and international publications.
Theoretical foundations of the model Articles defining the physical and biomechanical principles.
Systemic musculoskeletal biomechanics: a clinical model based on vector analysis
Isometric contractions, muscle length, and stretching: what the evidence says
How muscle shortening generates joint conflict: the role of connective tissue
Do antigravity muscles really oppose gravity?
Why joint conflict develops: vector analysis of muscular forces
Segmental analysis Vector analysis of the main joint and spinal regions.
Cervical hyperlordosis, straightening, and forward head: biomechanical causes and disc compressions
Thoracic kyphosis, lumbar lordosis, and spinal straightening: vector analysis in the sagittal plane
Vertebral rotation and radicular compression: vector analysis in the frontal and rotatory plane
Scoliosis: vertebral rotation, lateral deviation, and biomechanical intervention criteria
Cranio-cervico-mandibular disorders: when jaw pain comes from the neck and vice versa
Shoulder, elbow, and epicondylitis: vector analysis of the upper limb
Knee and hip: valgus, varus, hyperextension, and intra-articular compressions
Systemic model and clinical reasoning How the system organises, why symptoms develop, how to assess, and how to intervene.
Beyond muscle chains: the musculoskeletal system as a complex system
Pain neuroscience and muscle shortening: three systems, one final effector
Why the symptom returns: clinical reasoning in musculoskeletal pain diagnosis
Musculoskeletal assessment: why "correcting posture" is a conceptual error
Why muscle strengthening alone does not correct joint alignment
