This often prevents the proper functioning of a person, which makes him or her dependent on their guardians or family.

For this purpose, a study was conducted on a group of 60 people over 60 years of age. The study was conducted with the consent of the bioethical commission and under the supervision of physiotherapists. The relationship 146
