Abstract
Background: Nonspecific chronic low back pain is a common problem that can cause economic and social problems for an individual. Although there were alot of studies have reported the changes in the gluteus maximus activity in nonspecific chronic low back pain patients but it still debated.
Aim of Study: This study was conducted to investigate electromyographic activity of gluteus maximus muscle in nonspecific chronic low back pain male patients.
Subjects and Methods: Thirty nonspecific chronic low back pain male patients and 30 healthy male subjects with age from 20 to 40 years old with body mass index less than 30kg/m2 were recruited and assigned into 2 groups. Assessment was conducted by surface electromyography to assess gluteus maximus activity. Normalized root mean square of gluteus maximus muscle was collected and analyzed by SPSS version (24).
Results: There were significance decrease in electromy-ographic activity of right and left gluteus maximus in the study group when compared to control with p-values >0.005.
Conclusion: There was a decrease in the activity of the gluteus maximus in nonspecific chronic low back pain male patients when compared to the control group.
