“…Our study, however, did not find a statistically significant difference between groups with a slight increase in the degree of scapular upward rotation measured at 0 and 45 degrees of abduction in subjects with CNSLBP. This is consistent with the work of Taghizadeh et al (33) who found increased scapular upward rotation at zero-and 40-45-degrees abduction in subjects with CNSLBP as compared to healthy controls. They used, however, the lateral scapular slide test for assessment, while in our study, we used an inclinometer-based assessment.…”

Objective. To measure the surface electromyographic (EMG) activity of gluteus maximus (GMax) and latissimus dorsi (LD) muscles during walking and to measure the scapular upward rotation at different ranges of shoulder abduction in subjects with chronic nonspecific low back pain (CNSLBP) versus healthy controls. Methods. Twenty-six subjects with unilateral CNSLBP with a mean age (y) of 25.15 ± 4.11 and 26 age-matched healthy controls with mean age (y) of 23.88 ± 2.64 were recruited through direct referrals for this cross-sectional, comparative analysis. EMG activity of the GMax and contralateral LD muscles were recorded during treadmill walking using surface electrodes. Scapular upward rotation was measured using bubble inclinometers at 0°, 45°, 90°, 135°, and end range abduction. Analysis of variance (ANOVA) was used to analyze the difference between the two groups. Results. No statistically significant difference existed between the two groups regarding the recorded EMG activity of GMax and LD muscles during walking. Also, there was no statistically significant difference between the groups in scapular upward rotation measured at the different ranges of shoulder abduction. Conclusions. EMG activity of GMax and LD muscles and scapular upward rotation does not seem to be different between subjects with CNSLBP and healthy controls.

BACKGROUND: Patients with chronic low back pain (LBP) have an impaired dynamic spinal stability, which may lead to arm injuries. OBJECTIVES: To examine the latissimus dorsi and gluteus maximus muscles activation pattern and the upward scapular rotation in patients with chronic LBP. METHODS: Sixty-one right-handed males were divided into two groups: chronic LBP group (n= 31) and healthy controls (n= 30). The electromyography (EMG) activities of the right and left latissimus dorsi and gluteus maximus were recorded. The upward scapular rotation in different shoulder positions (neutral, 45∘, 90∘, 135∘ abduction and end range) was measured in both groups. RESULTS: The LBP group has a bilateral significant increased EMG of latissimus dorsi (p< 0.05) and significantly decreased EMG of gluteus maximus (p< 0.05) compared to the control group, without significant differences between the right and left sides (p> 0.05). There was a significant increase in upward scapular rotation in the LBP group relative to the control group in all shoulder abduction positions on both sides. The left side upward scapular rotation was more significant than the right (p< 0.05). CONCLUSION: Chronic LBP increased the latissimus dorsi muscle activities and decreased the gluteus maximus activities. It furthermore increased the upward scapular rotation in different shoulder abduction positions.
