@essefk: It possible to improve such extreme conditions even in old age ! Mr.P ( 80-years old ) here the change after 15 hours of special treatment. -Left video previously : He came to me because of his bent back. He has had this crooked posture for about 15 years. Has Osteoporosis, back pain. Everyday movements are very limited.He can hardly look straight ahead. -Right video afterwards : This is Mr.P after 15 special ( conservative )treatment hours. His back is straighter, his mobility has improved. Now it is easier for him to look straight.
