Rawal Med J Jan ;46(3):702-702.

Objective: To compare of upper extremity muscle strength in school going children with and without carrying heavy bags using a dynamometer. Methodology: Data were collected from different private schools and 54 children were selected through a non-probability convenient sampling. Only healthy children were included and those who had congenital diseases, recent trauma, and neurological disorders were excluded. A self-made questionnaire was used and the strength of upper extremity was checked by using a dynamometer in pounds. Results: Among 54 children, 37 (68.5%) were boys and 17 (31.5%) girls. Twenty-seven (50.0%) carried bag on shoulders and 27 (50.0%) used trolley bags. Shoulder flexors mean strength was 14.57±3.824 lb, extensors 14.44±3.627 lb, abductors 14.37±3.753 lb, adductors 14.41±3.418 lb, elbow flexors14.91±3.578, extensors 14.83±.884 and upper trapezius 15.63± 4.341lb. Conclusion: School-going children with carrying bags on their shoulder showed more muscle strength than those who did not carry bags on their shoulder.
