简要总结
This study aims to evaluate the effects of Global Postural Reeducation (RPG) using the K-Stretch hammock on workers at San Jorge University who experience neck and lower back discomfort due to prolonged sitting. The primary goal is to examine how this intervention impacts posture, musculoskeletal discomfort, flexibility, and range of motion, as well as participants' quality of life, stress levels, and sleep quality.
Neck and lower back discomfort are common issues that significantly impact individuals' quality of life and work performance. Global Postural Reeducation (RPG) is a therapeutic approach that focuses on stretching and strengthening muscle chains to improve posture and alleviate discomfort. This study is innovative in applying RPG combined with a specialized K-Stretch hammock to assess its potential benefits in a workplace setting.
Participants will include 32 administrative staff members aged 19 to 65 who work predominantly in seated positions and meet specific inclusion criteria. They will undergo a 6-week program involving bi-weekly 30-minute sessions. The study will also compare pre- and post-intervention results to evaluate changes in musculoskeletal discomfort, functional abilities, and physical alignment. Findings from this study may contribute to developing effective workplace interventions for musculoskeletal health.
详细描述
Here is the revised version of your text without dashes, bullet points, or special characters:
This clinical trial investigates the effects of Global Postural Reeducation combined with the use of a specialized K-Stretch hammock on improving musculoskeletal discomfort and related physical and psychosocial outcomes in a workplace setting. The study specifically targets neck and lumbar musculoskeletal discomfort among technical and administrative staff at San Jorge University who are exposed to prolonged sedentary work conditions.
The research is designed as a two-group randomized controlled intervention study focusing on the application of a structured RPG program. Participants are randomized into two groups: the intervention group, referred to as Group 1, and a delayed-intervention group, referred to as Group 2. Group 1 undergoes the RPG intervention during the initial six-week phase, while Group 2 receives the same intervention after the post-intervention evaluation of Group 1.
The RPG methodology utilizes sustained muscle chain stretches facilitated by the K-Stretch hammock, which supports participants in achieving better posture and reducing tension in key areas prone to discomfort due to sedentary behavior. The intervention includes twelve sessions, each lasting thirty minutes, conducted twice weekly. Sessions emphasize targeted stretching techniques for muscle chains affecting the cervical and lumbar spine, integrating relaxation and alignment strategies to promote improved physical and mental well-being.
Key features of the protocol include several aspects. The study type is interventional. Allocation is randomized. The intervention model is sequential assignment. Masking is not applied in this open-label trial. The primary purpose is treatment.

盲法说明
This study is open-label, and no masking is applied. Both participants and investigators are aware of the group assignments and the intervention being conducted. However, data analysis is performed on pseudonymized datasets to maintain objectivity and confidentiality. The individual responsible for assigning participant codes is not involved in data analysis, ensuring that any potential bias is minimized during the statistical evaluation process.

研究组 & 干预措施
Immediate Intervention Group: Participants receive the RPG intervention using the K-Stretch hammock
Participants in this arm will begin the intervention immediately after enrollment. The intervention involves 12 sessions of Global Postural Reeducation (RPG) using the K-Stretch hammock, delivered over six weeks with two 30-minute sessions per week. These sessions aim to improve posture, reduce cervical and lumbar musculoskeletal discomfort, and enhance flexibility and alignment.
Participants will undergo assessments before and after the intervention to measure changes in musculoskeletal discomfort, functional capacity, range of motion, muscle tone, stress levels, and quality of life. This arm serves to evaluate the immediate effects of the RPG intervention, providing data for comparison with the delayed intervention group.
干预措施: Global Postural Reeducation (RPG) using the K-Stretch hammock (Behavioral)
Delayed Intervention Group: Participants receive the RPG intervention after Group 1 completes it.
Participants in this arm will receive the Global Postural Reeducation (RPG) intervention using the K-Stretch hammock after Group 1 completes their intervention and post-intervention assessments. The intervention consists of 12 sessions conducted over six weeks, with two 30-minute sessions per week.
The sessions are designed to improve posture, reduce cervical and lumbar musculoskeletal discomfort, and enhance flexibility and alignment. Assessments for this group will include a baseline evaluation, conducted prior to the delayed intervention period, and a post-intervention assessment to measure changes in musculoskeletal discomfort, functional capacity, range of motion, muscle tone, stress levels, and quality of life.
This arm allows for a comparative analysis of immediate versus delayed intervention outcomes to assess the overall effectiveness of the RPG program.

结局指标
主要结局
Cervical and Lumbar Musculoskeletal Discomfort
时间窗: Immediate Intervention Group: Just before the intervention, immediately after (6 weeks), and 6 weeks post-intervention (12 weeks). Delayed Intervention Group: 6 weeks before the intervention, just before, and immediately after the intervention (6 weeks).
Measured using the Cornell Musculoskeletal Discomfort Questionnaire (CMDQ). This tool assesses the severity and frequency of discomfort in cervical and lumbar regions.
Cervical and Lumbar Musculoskeletal Discomfort Scale
时间窗: Immediate Intervention Group: Just before the intervention, immediately after (6 weeks), and 6 weeks post-intervention (12 weeks). Delayed Intervention Group: 6 weeks before the intervention, just before, and immediately after the intervention (6 weeks).
Measured using a Numerical Rating Scale (NRS)
Improvement in Quality of Life
时间窗: Immediate Intervention Group: Just before the intervention, immediately after (6 weeks), and 6 weeks post-intervention (12 weeks). Delayed Intervention Group: 6 weeks before the intervention, just before, and immediately after the intervention (6 weeks).
Assessed using the EUROQOOL-5D questionnaire, which evaluates mobility, self-care, usual activities, pain or discomfort, and anxiety or depression to determine participants' overall quality of life. The EQ-5D-5L index value ranges from -0.285 (worst possible health state) to 1 (best possible health state), where higher scores indicate a better quality of life. Additionally, the EQ-VAS (EuroQol Visual Analogue Scale) ranges from 0 to 100, with 0 representing "the worst health state imaginable" and 100 representing "the best health state imaginable."
