Correlation Between Phone Screen Time and Lumbar Flexibility Among Young Adults Across Ahmedabad City

BACKGROUND AND NEED OF RESEARCH: The number of smartphone users has significantly increased over time. Frequent smartphone usage compels individuals to maintain awkward postures, which may elevate the risk of musculoskeletal disorders and discomfort. Holding a smartphone in different positions can either enhance cervical flexion or alter the alignment of the thoracic and lumbar spine. However, research on how phone screen time influences lumbar spine flexibility remains limited. AIM AND OBJECTIVE: This study aims to investigate correlation between phone screen time and lumbar flexibility among young adults, exploring how prolonged phone usage may affect spinal health and mobility. METHOD: A correlation study was conducted with 56 young adults aged 18-25 years both males and females were included. Participants completed Mobile use Screen Test for phone screen time and lumbar flexibility was assessed using Modified - Modified Schober’s Test. RESULTS: Data of study shows non-normal distribution hence spearman test was applied. The result shows moderate negative correlation between phone screen time and lumbar flexibility in flexion (r = -0.637, p <0.01) and in extension (r =-0.686, p <0.01). CONCLUSION: The findings indicate significant negative correlation. Specifically, higher phone screen time is associated with decreased lumbar flexibility. Key words: Phone screen time, lumbar flexibility, spinal health, young adults.
