The aim of this study was to evaluate the changes in the parametres of the spine (total mobility of dorsolumbar spine and lumbar part of spine), to find out the changes of dynamic and isometric abdominal muscle endurance, dynamic and isometric back extensor muscle endurance, and isometric endurance of scapula muscle, the mobility of the shoulders and the pain severity in adolescents with Scheuermann disease and those who have postural kyphosis. 30 adolescents ( 16 boys and 14 girls ) with age of 13-17 years old were taking part in this study. Fifteen with Scheuermann’s disease went physiotherapy in rehabilitation center. The other fifteen with postural kyphosis did the same exercise programm at home. All of them exercised 22 days, 40 minutes a day. Such methods as spine flexibility measurement, Schober’s sign, tests for evaluating the strength of dynamic and isometric abdominal and back extensor muscle endurance, scapula muscle isometric endurance, shoulders mobility test, pain functional index and pain scale were used. CONCLUSION: After kinesitherapy treatment Patients with postural kyphosis had bigger mobility. But endurance of muscle strength increased more for the patients with Scheuermann‘s disease using kinesitherapy method.Pain Index and pain scale results after kinesitherapy dicreased more for the patients with Scheuermann‘s disease.
