As a rule, spasticity will worsen when you stop treatment. Muscles and tendons shorten, the joints become stiffer and incorrect posture persists permanently without therapeutic intervention. This leads to an ever-increasing restriction of movement. The declining mobility makes coping with everyday life more difficult, reduces quality of life in general and will increase pain. . According to the International Classification of Function, Disability and Health (ICF) of the World Health Organisation (WHO), most people with spasticity are likely to experience a relevant reduction in their participation in social and professional life if spasticity is not treated. ⁶

⁶ CF is the WHO framework for measuring health and disability at both individual and population levels. ICF was officially endorsed by all 191 WHO Member States in the Fifty-fourth World Health Assembly on 22 May 2001(resolution WHA 54.21) as the international standard to describe and measure health and disability.
