Intervention
The exercise class started with 10-min warm-up exercises (including stretching and balance exercises), and then continued for 30–40 min performing corrective exercises after the researcher in groups and individually, according to the conditions of each sample. At the end of the training class, cooling exercises and returning to the initial state were carried out for about 10 min. The intervention group performed corrective exercises for 8 weeks and 3 sessions per week and each session lasted for one hour. Exercises were designed based on each person’s ability and the principles governing the exercise, including the exercise intensity, gradual increase in exercise intensity, exercise duration, the principle of load progression, and the movement pattern of the exercise [All the exercises were done by one of the researchers and under the supervision of a physiotherapy specialist. Participants were asked not to perform any additional exercise. The control group was asked to do their normal daily activities and not participate in any exercise program. After completing the study, the control group will undergo the exercise intervention protocol.
