Clinical manifestations of Kashin-Beck disease in Nyemo Valley, Tibet

Clinical manifestations of Kashin-Beck disease have been studied in Central Tibet. Statistical analysis of physical signs allowed a definition of the clinical diagnosis and a scale for the functional severity for the disease to be drawn up. This classification is used for the assessment of patients who received palliative physical treatment. A group of 136 patients have been examined and their disabled joints classified according to pain, bony enlargement and restriction of movement. 57% were between 20 and 35 years of age. The patients mainly complained about their distal weightbearing joints. The clinical evolution of the disease is described from childhood to adult life.
