In recent years, sacroiliac syndrome has been widely accepted by many different health professions as one of the major contributors to low back pain. Manipulation to effect the relief of the condition has thus far proven to be one of the most effective methods. Comparatively little research has however been done on the different forms of physical therapy that can be used in conjunction with a manipulation so as to maximise its affect

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.

Abstract Context: Back pain is common in adolescents. Participation in sports has been identified as a risk factor for the development of back pain in adolescents, but the influence of sports participation on treatment outcomes in adolescents has not been adequately examined. Objective: To examine the clinical outcomes of rehabilitation for adolescents with low back pain (LBP) and to evaluate the influence of sports participation on outcomes. Design: Observational study. Setting: Outpatient physical therapy clinics. Patients or Other Participants: Fifty-eight adolescents (age  =  15.40 ± 1.44 years; 56.90% female) with LBP referred for treatment. Twenty-three patients (39.66%) had developed back pain from sports participation. Intervention(s): Patients completed the Modified Oswestry Disability Questionnaire and numeric pain rating before and after treatment. Treatment duration and content were at the clinician's discretion. Adolescents were categorized as sports participants if the onset of back pain was linked to organized sports. Additional data collected included diagnostic imaging before referral, clinical characteristics, and medical diagnosis. Main Outcome Measure(s): Baseline characteristics were compared based on sports participation. The influence of sports participation on outcomes was examined using a repeated-measures analysis of covariance with the Oswestry and pain scores as dependent variables. The number of sessions and duration of care were compared using t tests. Results: Many adolescents with LBP receiving outpatient physical therapy treatment were involved in sports and cited sports participation as a causative factor for their LBP. Some differences in baseline characteristics and clinical treatment outcomes were noted between sports participants and nonparticipants. Sports participants were more likely to undergo magnetic resonance imaging before referral (P  =  .013), attended more sessions (mean difference  =  1.40, 95% confidence interval [CI]  =  0.21, 2.59, P  =  .022) over a longer duration (mean difference  =  12.44 days, 95% CI  =  1.28, 23.10, P  =  .024), and experienced less improvement in disability (mean Oswestry difference  =  6.66, 95% CI  =  0.53, 12.78, P  =  .048) than nonparticipants. Overall, the pattern of clinical outcomes in this sample of adolescents with LBP was similar to that of adults with LBP. Conclusions: Adolescents with LBP due to sports participation received more treatment but experienced less improvement in disability than nonparticipants. This may indicate a worse prognosis for sports participants. Further research is required.
