Summary Hemophilia A and B are two X-linked recessive bleeding disorders caused by deficiency or absence of coagulation factor VIII and IX, respectively. There are more then 100 patients with this disorder in Lithuania. Affected individuals develop a variable degree of haemorrhage predominantly into joints and muscles. The severity of bleeding symptoms is correlating well with the residual activities of the corresponding clotting factors. Thus, patients with severe disease (F VIII / F IX < 1 %) usually experience recurrent spontaneous bleeding episodes while non-severely affected patients (F VIII / F IX > 1%) mainly bleed unop provocation. People who suffer from hemophilia are troubled by deformation of joints, alternation of limbs' length, arthrosis aches, and muscle contractures. The experience of latter summer camps showed that there was success to decrease those handicap phenomena significantly. That was reached by hemophilia patients' active physical activity at the seaside and kinesitherapy procedures. Evaluating the efficiency of kinesitherapy for the joint amplitude and muscle strength for those who suffer from hemophilia, it was depended on the dynamics of joints movements, measuring of arms and legs segments size, determination of muscle strength by Brooke's modified scale. Patients suffering from 19A and B forms of disease participated in the survey. They were divided into 2 groups according to the age - children up to 16 years of age and adults over 16 years of...
