Study summary

The aim of our study is to investigate the effectiveness of exercise against work-related musculoskeletal disorders in tea workers.

Read the detailed description

Individuals who volunteer to participate in the study will be evaluated considering the inclusion and exclusion criteria, and participants will participate in the study after reading and signing the Informed Consent Form. Tea workers who collect tea will be divided into 2 groups. .Demographic Information Form, Visual Analogue Scale (VAS), Upper Extremity Discomfort Analysis, Rapid Upper Extremity Assessment (RULA), Sleep Quality, Scandinavian Musculoskeletal System Questionnaire will be given to the participants of both groups. The surveys will be carried out face to face. After the application of the surveys, statistical data will be obtained. analyzes will be made. One group will be given exercise, the other group will not be given exercise. Post-exercise surveys will be conducted again to check the effectiveness of the exercise.

What researchers measure

Primary outcomes

  1. Arm Shoulder and Hand Problems Questionnaire

    It is a questionnaire developed by the American Academy of Orthopedic Surgeons (AAOS) based on the World Health Organization (WHO) model and used to evaluate upper extremity function status. The survey consists of three parts, and for all questions in the scale, the person marks the answer that suits him or her on a 5-point Likert system (1: no difficulty, 2: mild difficulty, 3: moderate difficulty, 4: extreme difficulty, 5: not able to do it at all). According to the results of the Arm Shoulder and Hand Problems Questionnaire survey; A result between 0-100 is obtained from each section (0: no problem, 100: maximum problem).

    Time frame: 14 weeks

  2. Nordic Musculoskeletal Survey

    It consists of 11 questions asked as a reference from 9 body regions shown on a visual body diagram of neck, shoulder, back, elbow, hand, wrist, waist, hip, thigh, knee, foot, ankle, and corresponds to 99 data items. The questionnaire primarily questions the presence of pain in 9 body regions. If the person's answer is yes, he moves on to the relevant sub-questions.It is a selection scale rather than a rating.

    Time frame: 14 weeks

  3. Pittsburgh Sleep Quality Index

    The scale is a 19-item self-report scale that evaluates sleep quality and disturbance over the past month. It consists of 24 questions, 19 questions are self-report questions, 5 questions are questions to be answered by the spouse or roommate. The 18 scored questions of the scale consist of 7 components. Subjective Sleep Quality, Sleep Latency, Sleep Duration, Habitual Sleep Efficiency, Sleep Disturbance, Sleeping Medication Use, and Daytime Dysfunction. Each component is evaluated on a scale of 0-3 points. The total score of the 7 components gives the scale total score. Total score varies between 0-21. A total score greater than 5 indicates "poor sleep quality".

    Time frame: 14 weeks
