Effectiveness of Exercises Given Along With Ergonomics Training in Construction Workers

The study is a randomized controlled study. This study will be conducted on construction workers in the Edremit district of Balıkesir. The study will be conducted by a physiotherapist. Participants will be divided into two groups. The construction workers included in the study will be divided into an experimental group and a control group using a simple randomization method. Randomization will be conducted using a sealed envelope method. All participants will sign an informed consent form before the study begins. The assigned exercises will be monitored using an exercise tracking chart. The control group will receive only ergonomics training. The experimental group will receive both ergonomics and exercise training. Participants will receive treatment three times per week, each session lasting 45-60 minutes, for 12 weeks.

• ergonomics training (Other): Each of the control group participants will receive separate ergonomics training. The content of this training will include the topics of "what is ergonomics, the purpose of ergonomics, musculoskeletal diseases in employees, work-related musculoskeletal risk factors.
• exercise + ergonomics training (Other): Each of the control group participants will receive separate ergonomics training. The content of this training will include the topics of "what is ergonomics, the purpose of ergonomics, musculoskeletal diseases in employees, work-related musculoskeletal risk factors. Other: exercise program stretching exercises strengthening exercises waist exercises core exercises relaxation exercises

Primary outcomes

• The Pittsburgh Sleep Quality Index [14 weeks]: Pittsburgh Sleep Quality Index; It evaluates sleep duration, sleep disturbance, sleep efficiency, subjective sleep quality, sleep medication use, daytime dysfunction, and sleep delay and consists of a total of 24 questions. 19 of them are self-report scales and 5 of them consist of questions to be answered by a friend or spouse. There are 7 components with 18 questions scored in the scale, and each component is evaluated between 0 and 3 points. The total score ranges from 0 to 21, and 5 or more is an indicator of "poor sleep quality
• Maslach Burnout Scale [14 weeks]: The scale consists of 22 questions in total. A 5-point Likert scale is used to answer the questions. There are options such as 0- Never, 1- Rarely, 2- Sometimes, 3- Often, 4- Always. Volunteers are asked to tick the appropriate option for each question. The scale has 3 sub-categories. There are 9 items for the emotional exhaustion section, 5 items for the depersonalization section, and 8 items for the personal achievement section. People with high burnout levels are expected to have high scores on the emotional exhaustion section and depersonalization section, and low personal achievement scores. The scores that can be obtained from the subscales range from 0-36 for emotional exhaustion, 0-20 for depersonalization, and 0-32 for personal achievement.
• Nordic Musculoskeletal Questionnaire [14 weeks]: It is a scale used to determine the extent of pain in the musculoskeletal system. The purpose of this questionnaire is to identify and compare pain and complaints in parts of the body. There is an image showing the 9 parts of the body included in the questionnaire. These body parts; neck, shoulders, back, elbows, hands, waist, hips, knees and feet. The respondents are asked whether they have experienced problems such as pain and discomfort in their body parts in the last 12 months, in the last 4 weeks, and on the day of the assessment, and they are asked to mark this as yes or no.
• Fatigue severity scale [14 weeks]: The lowest score that can be obtained from the scale is 9, and the highest score is 63. The fatigue severity scale is the average value of nine sections. A high score indicates increased fatigue severity. The scale, including the day it was filled, questions the state of fatigue in the last 1 month.
