Assessment of change in cervical and shoulder posture due to carriage of different weight of backpack
Journal Title: Journal of Applied and Natural Science - Year 2017, Vol 9, Issue 2
Abstract
Present experimental research was planned to measure the percentage change in angle of cervical and shoulder posture of students due to carriage of different weights of backpack. For the above purpose total 30 students (15 boys and 15 girls) from the CBSE affiliated school of Meerut were selected by using the random and purposive sampling method. All the students were from the 7th class and belonged to the age group of 10-13 years. To measure the percentage change in cervical and spinal angle in terms of extension, flexion and range of motion (ROM), six experimental conditions were planned. These experimental conditions were as (1) change in cervical and spinal region in unloaded state without backpack, (2) with backpack on right shoulder, (3) with backpack on the both shoulder, (4) with backpack of 10 % reference body weight, (5) with backpack of 15 % reference body weight and (6) with backpack of 20 % reference body weight. These experiments were conducted by using by using inclinometer (Dualar IQ). Furthermore results were analyzed by using the mean, standard deviation (SD), range and ANOVA test.In result, it was found that the value of cervical and spinal region angles in static condition was increased with increase in weight of back pack i.e. 10 %, 15 % and 20 % of reference body weight in the girls and boys. Whereas, the angle of deviation of spinal and cervical region especially flexion and extension of boys and girls in dynamic condition was found to be decreasing with increase in 10 %, 15 % and 20 % body weight of backpack. Based on current study results, a schoolbag should not be more than 5% or body weight among the girl students and 10 % of body weight among boy students. Otherwise, it will be a risk factor for postural problems either immediately or during adulthood that needs to be cured urgently.
