Expert Guide “Sitting: When the Flows of Living Systems Are Impeded”

Blue Portance Knowledge Base · Non-commercial reproduction permitted with citation of the source

This section brings together the main sitting-related pain conditions, understood as possible manifestations of impeded flows in living systems: relative immobility, duration of exposure, concentration of support points, and loss of mechanical variability. Each entry links to a dedicated knowledge guide that explains the mechanical, functional, and neuro-tissue mechanisms involved.

Sitting-related pain – postural stresses and body mechanisms

  • Low back painLow back painLow back pain is pain in the lower back, located between the thoracolumbar junction and the gluteal fold. In the vast majority of cases it is described as common (non-specific): it is mechanical in origin and does not stem from a serious disease.Read the full entry : Low back pain while sitting
  • FibromyalgiaFibromyalgiaFibromyalgia is a chronic pain syndrome combining persistent widespread pain, fatigue, sleep disturbances and often difficulty concentrating, with no tissue damage that could on its own explain the intensity of the symptoms.Read the full entry : Fibromyalgia and prolonged sitting
  • Shoulder pain and postural compensations
  • Specific stresses of prolonged driving
