The demographic data of the participants as gender, age, dominant hand, educational background, smoking status, and the number of cigarettes per day were recorded by means of a specially prepared questionnaire for this study.

The body weight (kilograms), height (meters) will be measured and the body mass index (kg/m2) of each participant will be recorded.

They were scored as (5) for good-normal, (3) for moderately affected, (1) severely affected postures. The score is between 65-13 with the cut-off score ≥ 45 is very good, 44-40 is good, 39-30 is moderate, 29-20 is poor, ≤ 19 is bad posture.
