Investigation of the Effect of Screen Time Before Sleep on Posture Disorders and Dynamic Balance

NCT07541963 | Not Yet Recruiting

• 1 other identifier: Sleep&ScreenTime1
• Study Type: observational
• Target: 34
• Locations: 1 country
• Sites: 1

Brief 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. In addition, screen exposure before sleep may negatively affect sleep quality and neuromuscular performance, which may in turn influence postural control and balance.

Conditions

Postural Disorders; Balance Problems

Outcome Measures

Primary Outcomes (1)

• 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.

  Single assessment at baseline

Secondary Outcomes (2)

• Star Excursion Balance Test

  Single assessment at baseline

• Duration of pre-sleep screen exposure

  Single assessment at baseline

Study Arms (1)

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.

Other: Pre-sleep screen exposure assessment

Interventions

Pre-sleep screen exposure assessment OTHER

Pre-sleep screen exposure is evaluated using smartphone-based self-reported queries on duration and usage characteristics
