简要总结
The goal of this clinical trial is to learn if specific exercise protocol while at work works to treat musculoskeletal pain such as neck pain, back pain, or shoulders' pain in adults workers. It will also learn about the effectiveness of this exercise protocol in improving their mood while working. The main questions it aims to answer are:
- Does exercise while at work help in alleviating pain due to physical exertion?
- Does exercise while at work help in improving mood in workers? Researchers will compare the exercise group to a control group (no guided exercise during the intervention period) to see if exercise works to treat pain due to physical exertion in various working populations.
Participants will:
- Apply a specific exercise protocol adjusted to their workplace and their job's profile for 2 months with a frequency of 3 times per week
- Fill in questionnaires about their pain, mood state, fatigue scale, functional activities level (SF36), Neck disability Index at the beginning of the study, the end of the study and 2 weeks after the end.
详细描述
Participants' Inclusion and Exclusion Criteria
The study was announced at a public hospital in Northern Greece and within private companies, as described below. Inclusion criteria required participants to be healthcare employees, office employees (both remote and daily commuting workers), or workers involved in manual cargo handling, heavy industry, or agricultural work. Eligible participants were aged up to 67 years, had more than one year of experience in their current position, and had a diagnosis of work-related nonspecific musculoskeletal pain. Healthcare employees were defined as those working in hospital settings, specifically as surgeons or nurses. Office employees were defined as individuals performing administrative tasks in a seated position, such as secretaries, clerks, or typists.
For the purposes of this study, "nonspecific musculoskeletal pain" was defined as pain that cannot be attributed to fractures, direct trauma, or systemic disease, and for which there is no evidence of root compression requiring surgical treatment.
Description of the Exercise Protocol
The exercise protocol begins in a seated position with spinal mobility exercises that mobilize the hips, lumbar spine, thoracic spine, and cervical spine, alongside progressive activation of the peripheral joints in the upper limbs. This is followed by multiaxial functional exercises for the trunk and upper limbs, incorporating various movements (e.g., lateral bending and twisting) that simulate positions assumed by employees during work tasks.

研究组 & 干预措施
Exercise protocol at workspace
The exercise protocol at Workspace begins in a sitting position with spinal mobility exercises that mobilize the hips, lumbar spine, thoracic spine, and cervical spine, accompanied by progressive activation of the peripheral joints in the upper limbs. This is followed by multiaxial functional exercises for the trunk and upper limbs, which combine various movements (e.g., lateral bending and twisting) that simulate the positions employees assume while working.
Subsequently, exercises are performed in an upright position, focusing on stretching and mobilizing the joints and nervous tissue to promote relaxation and release. Coordination, fluid movement, and controlled breathing are emphasized to help workers develop and maintain a stable core while on the job. These principles are essential for workers who are frequently exposed to stressors and physical exertion, as they seek to improve the quality of their movements-namely, smoothness, rhythm, and appropriate speed-while at work.
干预措施: Exercise protocol at workspace (Other)
Control group
Description: Control group. No exercise intervention. A printed document containing general guidelines for pain management and prevention of pain will be provided, in accordance with international guidelines for non-pharmacological interventions in the prevention of chronic non-specific spinal pain, along with recommended exercises for posture improvement.
结局指标
主要结局
Visual Analogue Scale
时间窗: From enrollment to the end of the treatment at 6 weeks and 2 weeks after the end of the treatment
Visual Analogue Scale (VAS) Pain intensity was assessed using the Visual Analogue Scale (VAS). Using a ruler, the score is determined by measuring the distance in millimeters on a 10-cm line between "no pain" and "severe pain," with a higher score indicating greater pain intensity.
Feeling Scale
时间窗: From enrollment to the end of the treatment at 6 weeks and 2 weeks after the end of the treatment
Feeling Scale (FS) The Feeling Scale (FS) is an 11-point bipolar rating scale measuring current mood on a valence dimension. The scale ranges from -5 ("very bad") to +5 ("very good"), with intermediate points such as -3 ("bad"), -1 ("fairly bad"), 0 ("neutral"), +1 ("fairly good"), and +3 ("good").
Neck Disability Index
时间窗: From enrollment to the end of the treatment at 6 weeks and 2 weeks after the end of the treatment
The Neck Disability Index (NDI) was used to measure functional disability due to neck pain. Widely regarded as the most valid tool for assessing neck pain-related disability, it consists of 10 questions covering the impact of neck pain on daily activities, including personal care, lifting, reading, working, driving, sleeping, and recreation, as well as on pain itself (e.g., intensity, headache, concentration). Each item is scored from 0 to 5, producing a total score ranging from 0 (no disability) to 50 (maximum disability). Higher scores indicate greater pain and functional disability. The Greek version of the NDI has high validity (Cronbach's alpha: 0.85) and excellent reliability (ICC: 0.93).
Fatigue Scale
时间窗: From enrollment to the end of the treatment at 6 weeks and 2 weeks after the end of the treatment
The Fatigue Scale is an 11-item measure that distinguishes between mental fatigue (four items) and physical fatigue (seven items), capturing cognitive difficulties and physical tiredness, respectively. This scale uses a five-point rating system (1 = "never" to 5 = "always") and can produce a total fatigue score. It has demonstrated reliability, validity, and sensitivity to treatment changes.
Short-Form Health Survey 36 - SF-36
时间窗: From enrollment to the end of the treatment at 6 weeks and 2 weeks after the end of the treatment
The SF-36 is a widely used questionnaire assessing overall health and quality of life across eight domains: physical functioning, role limitations due to physical health, role limitations due to emotional problems, social functioning, bodily pain, general health perceptions, vitality, and mental health. The SF-36 provides scores for each domain and summary scores for physical and mental health, and is commonly used in both clinical and research settings to evaluate patient-reported outcomes.
Modified Fingertip-to-Floor Distance Test, Spinal Lateral Flexion
时间窗: From enrollment to the end of the treatment at 6 weeks and 2 weeks after the end of the treatment
This simple clinical test assesses spinal mobility, particularly in the lower back and hamstrings. The distance between the fingertips and the floor is measured as the participant bends forward as far as possible with knees straight and feet together. This test evaluates flexibility, range of motion, and any movement restrictions.
Lateral Spinal Flexion Range of Motion
时间窗: From enrollment to the end of the treatment at 6 weeks and 2 weeks after the end of the treatment
Lateral Spinal Flexion is a clinical assessment used to measure spinal range of motion during sideways bending. The test evaluates the ability to flex the spine laterally in both directions, helping identify any movement restrictions, imbalances, or asymmetries.
