Brief Summary

Background: Internet Gaming Disorder (IGD) is a behavioral addiction recognized in diagnostic classifications such as DSM-5 and ICD-11. While research historically focuses on psychological and social dimensions, prolonged screen exposure and static sitting postures during gaming may also lead to physical health concerns, including postural alterations, reduced neuromuscular performance, and increased fatigue. Objective:The purpose of this cross-sectional study is to evaluate and compare spinal posture, trunk and cervical muscle endurance, lumbopelvic stability, and perceived fatigue levels between young adult males with and without Internet Gaming Disorder. Methods \& Procedures:A total of 47 young adult male participants aged 18-30 were recruited and divided into two groups: an IGD group (n=24) and a control group (n=23) based on the Internet Gaming Disorder Scale-Short Form (IGDS9-SF). Physical activity level and sitting duration were documented using the International Physical Activity Questionnaire-Short Form (IPAQ-SF). Participants underwent the following evaluations: Spinal Posture: Non-invasive computer-aided sagittal spinal curvature and mobility measurements using the Spinal Mouse device (Baseline/IDIAG). Trunk Endurance: McGill Trunk Endurance Tests (Flexor, Extensor, and Bilateral Lateral Plank tests). Cervical Endurance: Deep Cervical Flexor and Cervical Extensor Endurance Tests. Lumbopelvic Stability: Pressure Biofeedback Unit (PBU) / Cuff test. Fatigue: Fatigue Severity Scale (FSS). Statistical Approach:Data are analyzed using SPSS (version 22.0). Normality distribution is examined visually (histograms) and analytically (Shapiro-Wilk test). Descriptive statistics are reported as mean ± standard deviation for continuous parameters. Group comparisons for parametric data are performed using the Independent Samples t-test, and non-parametric data are compared using the Mann-Whitney U test. Statistical significance is set at p \< 0.05

Outcome Measures

Primary Outcomes (5)

• Postural Analysis

  In this study, spinal posture, mobility and structural-mechanical variables in the sagittal plane were assessed in the IOOB group and the control group using the Spinal Mouse device. The Spinal Mouse is a computer-assisted device that non-invasively assesses the range of motion of the spine in the sagittal plane.

• Posture Analysis

  In this study, spinal posture, mobility and structural-mechanical variables in the sagittal plane were assessed in the gaming disorders group and the control group using the Spinal Mouse device. The Spinal Mouse is a computer-assisted device that non-invasively assesses the range of motion of the spine in the sagittal plane.

  Baseline

• Body Endurance Tests

  The test comprises an endurance test of the trunk flexor and extensor muscles and a right-left lateral plank test. The trunk flexor endurance test was performed with the hips and knees flexed to 90° and the trunk supported at 60°. Once the participant was ready, the support was removed, and the time maintained in this position was recorded in seconds.The trunk extensor endurance test was performed with the participant prone, with the trunk unsupported from the level of the anterior superior iliac spine and the hands placed on a support. The participant crossed the arms over the chest and extended the trunk to maintain a horizontal position.The trunk lateral flexor endurance test was performed in a side-lying position, with the lower arm under the head and the upper arm parallel to the trunk or at waist level. Participants lifted their hips to maintain a straight body position, and the holding time was recorded in seconds. The test was performed on both sides, wit

  Baseline

• Cervical Endurance Tests

  Cervical endurance tests are measurement methods widely used in clinical and research settings to assess the endurance of the neck muscles.The test was performed in a supine position with the knees flexed. Participants were instructed to perform a chin tuck and lift the head and neck approximately 2.5 cm (1 inch) above the table. The time the position was maintained was recorded.

  baseline

• Lumbopelvic Stability Sleeve Test

  The test was performed in a supine position with the feet elevated 20 cm above the table. A pressure cuff inflated to 40 mmHg was placed under the lumbar region. Participants performed an abdominal drawing-in maneuver to maintain lumbopelvic stability, and the duration for which the pressure was maintained was recorded.
