An interventional study of Postural Reeducation Program in Musculoskeletal Pain, sponsored by University of Vigo. Completed at 1 site in Portugal. Open to participants aged 13 Years to 15 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2026-02-13.

This study evaluated whether a postural reeducation program could improve spinal posture and reduce musculoskeletal pain in adolescents who frequently use digital devices. Prolonged screen use is common among students and is often associated with inadequate sitting or standing postures, which may increase back and neck pain.
A total of 187 adolescents participated in the study. Students were assigned to an experimental group or a control group. The experimental group received a 12-week intervention integrated into the warm-up phase of Physical Education classes, while the control group continued with the usual warm-up used in these classes. The experimental group performed two sessions per week, each lasting 15 minutes, at the beginning of the class. Initially, students completed strength and mobility exercises for the spine and shoulder girdle. From the third week onward, active global stretching postures were added to improve flexibility and postural control.
Spinal posture was assessed at baseline and after the intervention using a noninvasive device (SpinalMouse®). Pain and postural habits were evaluated using a validated questionnaire. Adolescents who participated in the postural reeducation program showed improvements in postural alignment and functional mobility, as well as reductions in back and neck pain, compared with the control group.
This study suggests that a brief school-based postural reeducation program may be an effective preventive strategy to promote spinal health and reduce musculoskeletal pain in adolescents.
This study aims to evaluate the effects of a school-based postural reeducation program on spinal posture, functional mobility, and musculoskeletal pain in adolescents enrolled in lower secondary education (middle school level) who frequently use digital devices. Prolonged use of mobile phones, tablets, and other electronic devices is highly prevalent in this population and is associated with inadequate sitting and standing postures, increased thoracic kyphosis, and greater prevalence of neck and back pain. Preventive strategies implemented in school settings may help mitigate these negative musculoskeletal outcomes.
The primary objective of this study is to determine whether a 12-week intervention using a protocol based on strength and mobility exercises, combined with self-postures from the Global Active Stretching method and grounded in the principles of Global Postural Reeducation, integrated into Physical Education (PE) classes, improves spinal alignment and reduces pain perception in adolescents. Secondary objectives include assessing changes in postural habits related to digital device use and spinal mobility.
This study employed a repeated-measures pretest-posttest quasi-experimental controlled design with two groups parallel: an experimental group receiving the intervention and a control group continuing the usual PE warm-up. A total of 187 adolescents participated. During the first week, baseline assessment was performed, including spinal posture evaluation and questionnaire administration. The intervention program was then delivered over 12 consecutive weeks.
The intervention was implemented at the beginning of PE classes and consisted of two 15-minute sessions per week. The sessions included strength and mobility exercises for the spine and shoulder girdle based on the protocol proposed by Feng et al. (2018). In addition, active global stretching postures from the Souchard Active Global Stretching (AGS) method were progressively introduced to improve flexibility and postural control.
Spinal morphology in the sagittal plane was assessed at pretest and posttest using the non-invasive SpinalMouse® device. Postural habits and musculoskeletal pain were assessed using the validated Back Pain and Body Posture Evaluation Instrument for Children and Adolescents (BackPEI-CA) questionnaire. All measurements were conducted under standardized conditions to ensure internal validity.
Participation involves minimal risk, limited mainly to temporary muscular discomfort during exercise performance. Potential benefits include improved postural awareness, spinal alignment, mobility, and musculoskeletal health.
This study is expected to contribute evidence supporting the feasibility and effectiveness of brief school-based postural reeducation programs as a low-cost preventive strategy to promote spinal health in adolescents.

Exclusion Criteria:
Participants assigned to the experimental group will receive a 12-week postural reeducation program integrated into Physical Education classes. The program includes strength and mobility exercises for the spine and shoulder girdle and active global stretching postures designed to improve flexibility and postural control. Sessions are delivered twice per week for 15 minutes at the beginning of the class.
Behavioral: Postural Reeducation Program
Participants assigned to the control group will follow their usual Physical Education classes and standard warm-up routines. They will not receive any specific postural reeducation program or additional structured exercises beyond the regular school curriculum.
Behavioral: Postural Reeducation program The intervention consists of a 12-week school-based program integrated into Physical Education classes. Students perform two 15-minute sessions per week including strengthening and mobility exercises for the spine and shoulder girdle, followed by active global stretching postures aimed at improving flexibility and postural control.

Change in sagittal spinal curvature (thoracic kyphosis and lumbar lordosis)
Sagittal spinal posture will be assessed using the Spinal Mouse® device at baseline (pre-intervention) and after 14 weeks (post-intervention). Thoracic kyphosis and lumbar lordosis angles will be recorded in degrees (°). The outcome will be expressed as the difference in angular values between baseline and post-intervention and compared between the intervention and control groups.
Time frame: Baseline and 14 weeks (post-intervention)
Change in thoracic and lumbar range of motion
Thoracic and lumbar range of motion (ROM) will be assessed using the Spinal Mouse® device at baseline (pre-intervention) and after 14 weeks (post-intervention), during maximum trunk flexion. ROM will be recorded as a global angular value in degrees (°). The outcome will be expressed as the difference in angular values between baseline and post-intervention and compared between the intervention and control groups.
Time frame: Baseline and 14 weeks (post-intervention)
Change in low back pain intensity (BackPEI-CA)
Low back pain intensity will be assessed using the Back Pain and Body Posture Evaluation Instrument for Children and Adolescents (BackPEI-CA) at baseline (pre-intervention) and after 14 weeks (post-intervention). Pain intensity will be reported as a questionnaire score. The outcome will be expressed as the change in score between baseline and post-intervention and compared between the intervention and control groups.
Time frame: Baseline and 14 weeks (post-intervention)
Plan to share: No — Individual participant data will not be shared because the study involves minors and contains sensitive health-related information. Data will be used exclusively for research purposes within the project team, in accordance with institutional and ethical approvals.
