About this study
Official title: The Effect of Ergonomics and Exercise Training on Musculoskeletal Disorders in Female Dairy Farmers: A Randomized Controlled Trial
The aim of this research is to comparatively examine the effects of ergonomics training and the combined application of ergonomics and structured exercise training on work-related musculoskeletal disorders in female farmers actively engaged in milking.
Read the detailed description
The study will assign female farmers actively engaged in milking to two groups using a simple randomization method: a control group (ergonomics training) and an experimental group (ergonomics and exercise training). The control group will receive standard ergonomics training aimed at reducing ergonomic risk factors encountered during milking. The experimental group will receive the same ergonomics training as the control group, plus a structured exercise program consisting of stretching, strengthening, and posture exercises. The exercise program will be planned based on progressive loading principles, muscle group-specific exercise selection, set-repetition arrangement, and standardization of rest intervals. The intervention period is 12 weeks, with exercises performed 3 days a week. All participants will be evaluated before and after the intervention using the Visual Analog Scale, Nordic Musculoskeletal Questionnaire, Quick Disabilities of the Arm, Shoulder and Hand, and the World Health Organization Quality of Life Short Form, all within the same assessment protocol.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Other: Standardized Ergonomics TrainingOther
The control group will be given standard ergonomics training which includes proper body mechanics, correct working posture and musculoskeletal protection principles during milking.
Other: Standardized Ergonomics Training Plus Structured Exercise ProgrammeOther
The exercise group will receive the same ergonomics training as well as a structured exercise program consisting of stretching, strengthening and posture exercises. The exercise program will be planned to last three days a week for a total of 12 weeks.
| Study group | Role | What they receive |
|---|---|---|
| Ergonomics Training | Active comparator | Participants receive three individual face-to-face ergonomics training sessions of approximately 60 minutes each at baseline and at the end of weeks 4 and 8. Training addresses appropriate body mechanics, working posture during milking, stool and equipment positioning, load handling, work-rest organization, wrist positioning and musculoskeletal protection. Participants also receive an illustrated brochure and telephone contact every two weeks. Receives: Other: Other: Standardized Ergonomics Training |
| Ergonomics Training Plus Structured Exercise | Experimental | Participants receive the same ergonomics training as the control group plus a 12-week home-based, equipment-free structured exercise programme performed three non-consecutive days per week. Each session lasts approximately 45-50 minutes and includes warm-up, stretching, postural and scapular control exercises, and progressive calisthenic strengthening exercises.

What is being measured
The primary outcome is the main question the study is designed to answer.
Change in Work-Related Musculoskeletal Pain Intensity Assessed With the Visual Analogue Scale
Pain intensity is assessed using a Visual Analogue Scale ranging from 0 to 10, where 0 indicates no pain and 10 indicates unbearable pain. Participants rate their overall work-related musculoskeletal pain considering the neck, shoulders, and lower back. Higher scores indicate greater pain intensity.
Measured: Baseline (week 0) and post-intervention (week 12)
Secondary outcomes (4)
Change in Upper-Limb Functional Disability Assessed With the QuickDASH
The QuickDASH is an 11-item questionnaire scored from 0 to 100. Higher scores indicate greater upper-limb disability.
Measured: Baseline (week 0) and post-intervention (week 12)
Change in Depressive Symptoms Assessed With the Beck Depression Inventory
Depressive symptoms are assessed with the Beck Depression Inventory. Higher total scores indicate greater depressive symptom severity.
Measured: Baseline (week 0) and post-intervention (week 12)
Change in Quality of Life Assessed With the WHOQOL-BREF
Quality of life is assessed using the WHOQOL-BREF. The physical health, psychological health, social relationships, and environment domains are scored and transformed to a 4-20 scale. Higher scores indicate better quality of life.
Measured: Baseline (week 0) and post-intervention (week 12)
Musculoskeletal Symptom Prevalence Assessed With the Nordic Musculoskeletal Questionnaire
The Standardised Nordic Musculoskeletal Questionnaire assesses musculoskeletal symptoms in nine body regions: neck, shoulders, upper back, elbows, wrists/hands, lower back, hips/thighs, knees, and ankles/feet. At baseline, the 12-month recall section is used; at week 12, the 7-day recall section is used. Results are reported descriptively because the recall periods differ between assessments.
Measured: Baseline (12-month recall) and week 12 (7-day recall)
