About this trial
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.

Treatments tested in this trial
Global Postural Reeducation (RPG) using the K-Stretch hammock
BehavioralThe intervention involves Global Postural Reeducation (RPG) using the K-Stretch hammock. This therapeutic approach focuses on sustained stretching of muscle chains to improve posture, reduce cervical and lumbar musculoskeletal discomfort, and enhance flexibility. Participants complete 12 sessions over six weeks, with two 30-minute sessions per week. Each session includes guided exercises that target muscle imbalances, improve alignment, and alleviate tension caused by prolonged sedentary behavior. The K-Stretch hammock provides support for optimized stretching and alignment during the exercises.
Treatment groups
32 Participants
are divided into 2 treatment groupsGroup A: Immediate Intervention Group: Participants receive the RPG intervention using the K-Stretch hammockExperimental treatment 1 intervention
Group B: Delayed Intervention Group: Participants receive the RPG intervention after Group 1 completes it.Experimental treatment 1 intervention
Trial outcomes
Primary outcomes
1
Cervical and Lumbar Musculoskeletal Discomfort
Measured using the Cornell Musculoskeletal Discomfort Questionnaire (CMDQ). This tool assesses the severity and frequency of discomfort in cervical and lumbar regions.
Time frame
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).2
Cervical and Lumbar Musculoskeletal Discomfort Scale
Measured using a Numerical Rating Scale (NRS)
Time frame
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).3
Improvement in Quality of Life
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."
Time frame
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).Secondary outcomes
1
Improvement in Functional Capacity of Low Back
Assessed using the Oswestry Low Back Disability Questionnaire (ODI). This tool evaluates limitations in daily activities and the functional impact of lumbar discomfort. The score ranges from 0 to 100, where higher scores indicate greater disability: 0-20%: Minimal disability 21-40%: Moderate disability 41-60%: Severe disability 61-80%: Crippling disability 81-100%: Patient is either bed-bound or exaggerating symptoms
Time frame
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).2
Improvement in Functional Capacity of Neck
Assessed using the the Neck Disability Index Questionnaire (NDI). Thise tool evaluates limitations in daily activities and the functional impact of cervical. The score ranges from 0 to 50, where higher scores indicate greater disability: 0-4 (0-8%): No disability 5-14 (10-28%): Mild disability 15-24 (30-48%): Moderate disability 25-34 (50-68%): Severe disability 35-50 (70-100%): Complete disability
Time frame
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).3
Reduction in Perceived Stress
Measured using the Perceived Stress Scale (PSS), which quantifies participants' perceived stress levels over the last month by scoring their feelings and thoughts. The PSS ranges from 0 to 40, where higher scores indicate greater perceived stress. Scores between 0-13 suggest low stress, 14-26 indicate moderate stress, and 27-40 reflect high perceived stress.
Time frame
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).4
Enhancement in Range of Motion
Measured using a goniometer to determine improvements in cervical and lumbar spinal flexibility by quantifying the range of motion during specific movements.
Time frame
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).Sponsors and contacts
