Investigation of the Effect of Screen Time Before Sleep on Posture Disorders and Dynamic Balance
An observational study of Postural Disorders and Balance Problems, run by Saglik Bilimleri Universitesi at 1 site in Turkey (Türkiye).
Trial summary
The widespread use of electronic devices such as smartphones, tablets, and laptops has significantly increased screen exposure, especially before sleep. Prolonged screen use may contribute to poor posture by promoting forward head posture, rounded shoulders, and other musculoskeletal problems. Read more about this study

About this study
The widespread use of electronic devices such as smartphones, tablets, and laptops has significantly increased screen exposure, especially before sleep. Prolonged screen use may contribute to poor posture by promoting forward head posture, rounded shoulders, and other musculoskeletal problems. In addition, screen exposure before sleep may negatively affect sleep quality and neuromuscular performance, which may in turn influence postural control and balance.
Read the detailed description
Postural disorders arise from the disruption of the natural alignment of the spine and are often associated with muscle imbalances, joint stress, and pain. Incorrect posture caused by prolonged technology use has been reported to increase the risk of musculoskeletal problems among young adults.
Dynamic balance is an important component of postural control and is influenced by the integration of sensory input and neuromuscular responses. Sleep disturbances and lifestyle habits, including excessive screen exposure before sleep, may affect this complex system.
Therefore, the aim of this study is to investigate the effect of screen time before sleep on posture disorders and dynamic balance in healthy young adults. Participants aged between 18 and 35 years will be evaluated for screen usage habits before sleep. Posture analysis and the Star Excursion Balance Test will be used to assess posture alignment and dynamic balance performance.

| Study group | Role | What they receive |
|---|---|---|
| Healthy young individuals with pre-sleep screen exposure | 34 healthy volunteers between the ages of 18-35 were included in the study. Participants are assessed for screen exposure before sleep, posture disorders, and dynamic balance. Receives: Other: Pre-sleep screen exposure assessment |
What is being measured
The primary outcome is the main question the study is designed to answer.
Posture Analysis
Evaluation of body alignment including head position, shoulder alignment, spinal curvature, pelvic position, knee alignment, and foot posture from anterior, posterior, and lateral views.
Measured: Single assessment at baseline
Secondary outcomes (2)
Star Excursion Balance Test
Dynamic balance performance will be assessed by measuring the maximum reach distance in eight directions while maintaining single-leg stance.
Measured: Single assessment at baseline
Duration of pre-sleep screen exposure
The duration of screen exposure within 1 hour before bedtime will be assessed using self-report and recorded in minutes. Higher values indicate longer screen exposure before sleep.
Measured: Single assessment at baseline

Prolonged screen use may contribute to poor posture by promoting forward head posture, rounded shoulders, and other musculoskeletal problems. In addition, screen exposure before sleep may negatively affect sleep quality and neuromuscular performance, which may in turn influence postural control and balance.
