Relationship Between Forward Head Posture and Sagittal Lumbopelvic Alignment Among Smartphone Users

Egypt85 participantsStarted 2025-06-05

Plain-language summary

Forward head posture is a common postural abnormality characterized by anterior positioning of the head in the sagittal plane. This posture may increase biomechanical stress on the cervical spine and may be associated with compensatory changes in spinal and lumbopelvic alignment. This observational study will investigate the relationship between forward head posture and sagittal lumbopelvic alignment among male smartphone users aged 18 to 35 years. Craniovertebral angle will be measured using the APECS mobile application, and sagittal lumbopelvic alignment parameters will be measured using the Spine3D LiDAR system.

Inclusion Criteria: * Male participants aged 18 to 35 years. * Craniovertebral angle equal to or less than 50 degrees, measured photographically using the APECS mobile application. * Body mass index from 18.5 to 24.9 kg/m². * Smartphone use of at least 4 hours per day for at least 6 months. * Asymptomatic participants without diagnosed musculoskeletal or neurological conditions. * Medically stable participants. * Participants willing to provide informed consent. Exclusion Criteria: * History of trauma. * Major psychological problems. * Previous surgery involving the spine, abdomen, or shoulders. * Spinal deformity. * Lower limb deformity. * Low back pain. * Current or chronic pain in the neck, back, or pelvis. * Obesity. * Concomitant systemic diseases, including systemic lupus erythematosus, diabetes mellitus, sickle cell anemia, multiple sclerosis, fibromyalgia, or cancer. * Pregnancy. * Degenerative or radicular cervical spine disorders, including cervical spondylosis, cervical degenerative disc disease, cervical radiculopathy, or cervical spinal stenosis. * Degenerative or radicular lumbar spine disorders, including herniated disc or lumbar spinal stenosis. * Participation in regular postural correction therapy or specific spine-focused exercise programs within the previous 6 months.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
