A locomotor system reaches an  “optimal posture” when body weight is equally distributed on both feet on the frontal and sagittal plane and the barycentre coincides with the geometrical centre.

In an attempt to  maintain stability in statics and dynamics, a human body, regardless of age and sex, implements unilateral musculoskeletal adaptations of intersegmental joints. This condition gives rise to biomechanical adjustments at sacroiliac, coxofemoral, knee, talocrural and foot joints and subsequent paramorphisms of one hemisoma: the body weight will not be equally distributed on the footprint and the barycentre, although inside the support polygon, will be far from the geometrical centre.


Apparent or Functional Leg Length Discrepancy (FLLD) is one of the most common forms of neuro-musculo-skeletal paramorphism. The role of foot posture and functional leg length discrepancy in contributing to abnormal biomechanics of the pelvis is not sufficiently investigated. The aetiological aspects as well as postural attitude implications represent an open question in pelvic asymmetry evaluation and treatment.

According to our researches, pelvic asymmetry due to FLLD can cause the anteverted hemipelvis, the femoral internal rotation on the transversal plane, and foot paramorphisms. The innovative NPoS device has been developed and patented to better investigate FLLD etiopathogenesis and to provide medical professionals a new reliable clinical method for the diagnosis and treatment of postural defects, which will grant the patient an optimum postural equilibrium.


NPoS (New Postural Solution)device consists of  two systems:

  • FIS (Foot Image System): a system which takes images of the non-weight-bearing foot, measures the foot equinus and defines the related shoes heel height.
  • Postural Optimizer System): a podometer of new generation which allows a comparative study of patients’ data both barefoot and with simulated heels height on the sagittal and frontal plane: to assess the equal body weight distribution on both feet, the geometric centre of the support polygon and the position of the centre of gravity (barycentre) of the patient must coincide. The assessed stability will lead to meaningful and long-lasting effects on patients’ psycho-physical health and preserving the state of joints.

The new obtained posture thanks to the results of NPoS analysis will optimize the biomechanics of the entire musculoskeletal system and will allowfoto1
