The posture is affected by the imbalance between the muscle force and also by reduction or increase in the muscle length. OBJECTIVE: To analyze the posture using posture screening mobile application among collegiates. METHODOLOGY: It is a non-experimental, observational study, sample size 200 subjects both genders between 19 to 23 years, more than 18.5 to 25 ratios of BMI were conveniently included in the study. The exclusion criteria was any congenital or acquired musculoskeletal problems and recent surgeries fractures and injuries. METHOD: A written informed consent was taken from the subjects. The posture assessment was taken using posture screening mobile application and was documented. RESULTS: The result shows the percentage of abnormal posture deviation among normal BMI collegiates. CONCLUSION: The study concluded that the prevention of musculoskeletal disorders among young individuals with normal BMI is one of the challenging issues among health care professionals. Keywords: posture, musculoskeletal disorder, posture screening mobile application Corresponding Author: Mrs. S.F.Mariyam Farzana Assistant Professor Email id: mariyamf@srmist.edu.in Introduction Musculoskeletal disorders describe the conditions that affect the muscle bones and joints. Many studies and literatures quotes that the prevalence of musculoskeletal disorder among students are increasing. The factors that contribute to musculoskeletal disorder are imbalance in biomechanics of body, improper posture, weak muscles and endurance 1 . A posture is defined as position of the body or the arrangements of the body segments relative to one another 2 . The posture can be either static or dynamic. During static posture, in certain positions such as standing, sitting, lying and kneeling, the body and its segments are balanced and maintained. Dynamic posture refers to the posture in which the body or its segments are capable of arranging and rearranging body segments to shape a wide variety of postures, but keeping an upright bipedal position which is ideal for humans, including movements such as walking, running, punching, jumping and lifting. Every specific posture research includes kinetic and kinematic analysis of all body segments 3 . Classical method of assessing the posture, in order to understand the optimal posture, it is necessary to understand the optimal alignment of the spine and other joints at rest. This is usually done by analyzing or using plumb line, the gravity should pass through specific points of the body 4 . On examination, the body should be viewed from three aspects anterior, posterior, lateral. The standard erect posture is where the gravity of the vertical line drawn through the center of gravity of the body is viewed from each side. The gravity line passes through the inner auditory meatus through the shoulder joint and approximately halfway via the cervical and lumbar vertebral bodies. At hip, it passes through the hip joint at the level of greater trochanter of femur. Then it
