The Impact of Prolonged Sitting on Sagittal Plane Postural Angle in School Going Adolescent through Photographic Method - A Study

Abstract

Sitting for more than >8hrs is considered under prolonged sitting. Adults generally spend 6–8 hours of sitting/ per day or more than 8hrs per day. Adolescents spent most of their days in supervised institutions like schools. During school hours children have very fewer breaks. School children spend a considerable amount of their waking hours at school, mostly seated. Adolescence and Childhood are important times in the human body's growth and development. The objective of this study is to investigate that is there is any impact of prolonged sitting on sagittal plane postural angle in school-going adolescents as they spent a large amount of time in a sitting position. A questionnaire was developed using self-made questions having a details about the participant demographic data, their sitting hours, phone usage hours, physical activity, etc.198 healthy school going students of age 15–19 years (study had 121 males & 77 females) were taken for the study. Anatomical markers were placed on the C7 spinous process, ear tragus, eye can thus & greater tuberosity of humerus to measure three angles i.e CHA (Craniohorizontal angle), CVA(craniovertebral angle) & SSA(sagittal shoulder angle). Photographs were taken in the sagittal plane from the left side of the participant's body via digital camera. Angles were measured via MB ruler 5.4 software. From the result it was found that there is no impact of prolonged sitting on a sagittal plane postural angle on upper limb angle(CHA, CVA & SSA) which we had taken in the study.
