| Amavata is a chronic systemic disorder described in Ayurveda, characterized by the involvement of Ama (undigested toxic material) and Vata dosa, producing systemic and articular symptoms. It closely resembles Rheumatoid Arthritis (RA) in modern medicine. Sandhi Vikruti (joint pathology) is the prime manifestation, which can be objectively assessed by X-ray. Radiological evaluation provides structural correlation of Ayurvedic descriptions of Sandhi-Vikara like sandhisankochoch, Sandhishotha (synovial inflammation/swelling), stambha (stiffness), sandhi graha (ankylosis) and other structural changes |
