The Effect of Exercise Given to Cashiers Along With Ergonomics Training on Pain and Work Performance

The work will be done with 60 cashiers. These cashiers will be selected on the condition that they work at least 40 hours a week. 60 employees will be randomly divided into two groups of 30 people each. All participants will be given ergonomics training. In addition, participants in the exercise group will be given a 12-week exercise program. These two groups will be randomly divided into control and exercise groups. Each group will be evaluated twice, at the beginning and at the end of the study.

• control (Other): There will be no interference ergonomics training
• exercise (Other): upper extremity strengthening exercises upper extremity stretching exercises ergonomics training posture training relaxation exercises

Primary outcomes

• Rapid Upper Limb Assessment [14 weeks]: It is an ergonomics risk assessment method that quickly analyzes the employee's upper extremity from an ergonomic perspective. It evaluates upper extremity movements in 14 separate steps. 8 of these steps are scored for arm and hand position, and 6 for neck and trunk position, according to the table. The minimum Rapid Upper Limb Assessment Score = 1, and the maximum Rapid Upper Limb Assessment Score = 7. A high score means high risk.
• occupational burnout scale [14 weeks]: This scale aims to measure the degree of professional burnout that may occur due to stress in business life. It consists of 20 questions in total. For each question there are options: 'Never, Rarely, Sometimes, Often, Always'. The person will choose what suits him/herself.Possible score ranges for all scales is 0-100.Higher score is more favorable.
• Nordic Extended Musculoskeletal Questionnaire [14 weeks]: It is one of the questionnaires used to evaluate the severity and impact of musculoskeletal symptoms. In the survey, the frequency and severity of pain in the 'Neck, Shoulder, Upper Back, Elbow, Hand-wrist, Kala, Knee, Foot-ankle' areas of the body are evaluated in the last 12 months.It is a selection scale rather than a rating.
• Pittsburgh Sleep Quality Index [14 weeks]: This index evaluates sleep quality and disturbance over the past month. It contains a total of 24 questions. 19 of these questions are answered by the person's self-assessment, and 5 of them are answered by the roommate who shares the same room with the person. The 5 questions answered by the person's roommate are not included when calculating the score. In scoring, the lowest (0) and the highest (21) points are obtained. A score of 4 and above indicates poor sleep quality.
• bournemouth neck survey [14 weeks]: Since the Bournemouth Neck Pain Questionnaire evaluates individuals physically, mentally, emotionally and socially, it is a survey that can give an idea about the quality of life of individuals with chronic neck pain. In the survey, he evaluates the problems he has experienced in the last week in 7 questions. In scoring, the lowest is (0) and the highest is (70). As the score increases, pain intensity increases.
