How Sitting Posture Affects Hip Muscle Strength in University Researchers

Not yet recruiting

Conditions: Neck Posture, Gluteus Maximus Strength, Sitting Pattern

Registration Number: CTRI/2025/06/088751

Lead Sponsor: Jamia Hamdard

Brief Summary: Following approval from the institutionalethical committee, an invite to participate in the study will be sent to theresearch scholars. A detailed explanation of the study objectives andprocedures will be provided, and written informed consent will be obtained fromall participants prior to enrolment. Eligible participants, based on thepredefined inclusion and exclusion criteria, were then organized into studygroups. The assessment protocol began with evaluation of forward head postureusing the Craniovertebral Angle (CVA), measured via standardized lateral-viewdigital photographs analyzed using Kinovea Software (Version 2023.1.1).Anatomical landmarks—the C7 spinous process and the tragus of the ear—weremarked, and a horizontal line was drawn from C7, with another line extendingfrom C7 to the tragus. The angle formed between these lines was recorded, andthe mean of three trials was used for analysis. Participants also provided asubjective self-report of their average daily sitting duration over a 7-dayrecall period, including academic, recreational, and screen-based activities.Subsequently, the strength of the gluteus maximus muscle was measured using theBiodex System 3 Isokinetic Dynamometer. Participants performed isokineticcontractions of hip extension, abduction, and adduction in the prone position,following standard manufacturer protocols. Additionally, rounded shoulderposture (RSP) was assessed by measuring the vertical distance from the acromionto the plinth in the supine position. All data were systematically recorded andcompiled into a master chart for statistical analysis to investigate therelationship between sitting duration, postural deviations (such as forwardhead posture), and gluteus maximus muscle strength.
