ABSTRACT
Aim: To study effect of upper limb activity on erector spinae muscle during different sitting postures among non specific low back pain students aged 18-21 years.
Materials and methods: 50 students from medical institutions (MBBS, BPTH, BDS, Nursing) in the age group of 18-21 years participated in the study for 6 months.
Result: Significant difference were revealed on the EMG values during high sitting and cross sitting at rest(p=0.0006). In comparison among females and males significant difference is seen in high sitting and cross sitting at rest with p value 0.025 and 0.006. There was no significant difference in erector spinae muscle activity between high sitting and cross sitting during unilateral and bilateral upper limb elevation.
Conclusion: The study result reveal that the amplitude of erector spinae muscle is more in high sitting as compared to cross leg sitting at rest, which shows erector spinae muscle works more in high sitting position as compared to cross leg sitting, whereas in unilateral or bilateral upper limb elevation activity (amplitude) of erector spinae muscle increases in high sitting as well as cross leg sitting position.
