BACKGROUND Low back pain (LBP) is a frequent reason for emergency department (ED) presentations with a global prevalence of 4.4%. Despite being common, the number of clinical trials investigating LBP in the ED is low. Recruitment of patients in EDs can be challenging due to the fast-paced and demanding ED environment. OBJECTIVE To describe the recruitment and response rates using a short message service (SMS) and an online survey system supplemented by telephone calls to recruit LBP patients and collect health outcomes in the ED. METHODS An automated SMS system was integrated into REDCap and used to collect patient-reported outcomes for an implementation trial in Sydney, Australia. We invited patients with non-serious LBP who presented to participating EDs at one, two and four weeks after ED discharge. Patients who did not respond to the initial SMS invitation were sent a reminder SMS or contacted via telephone. Recruitment rate was measured as the proportion of patients who agreed to participate and response rate as the proportion of participants completing the follow-up surveys at weeks two and four. Regression analyses were used to explore factors associated with response rates. RESULTS In total, 807 patients with non-serious LBP were invited to participate and 425 (53%) agreed to participate. The week-1 survey was completed by 416 (52%) participants. At week-2, the response rate was 87% (360/416) and at week-4 was 84% (351/416). Overall, 60% of the surveys were completed via SMS/online and 40% via telephone. Younger participants and those from less socioeconomically disadvantaged areas were more likely to respond to the survey via the SMS/online system. CONCLUSIONS Using an SMS/online survey system supplemented by telephone calls is a viable method to recruit patients with LBP and collect health outcomes in the ED. This hybrid system could potentially reduce the costs of using traditional recruitment and data collection methods (e.g. face-to-face, telephone calls only). CLINICALTRIAL

We aimed to examine systematically the available evidence on risk factors of low back pain (LBP) in athletes. We performed search without language restriction in PubMed, Ovid, Google Scholar, Scopus, and CINAHL. Longitudinal studies that examined possible risk factors of LBP in athletes were included in this systematic review. Based on methodological quality of studies, a best-evidence synthesis was conducted. Seven longitudinal studies were included, four of which had high methodological quality. Results showed that previous LBP, decreased lumbar flexion, and decreased lumbar extension are positively associated with LBP. There was moderate evidence for hip flexor tightness and high body weight as a risk factor. We found insufficient evidence for association between forward bending, previous injury, and amount of training per week, active years, age, and sex with LBP. In conclusion this study would provide a list of risk factors for LBP in athletes, though it showed a strong evidence for only a few including decrease lumbar flexion or extension, previous LBP, and high body weight. This review indicated a high heterogeneity of study characteristics including assessed risk factors and statistical techniques might limit the quality of evidence.

Abstract. When using Short Message Service (SMS) as a tool for data collection in psychological research, participants can be contacted at any time. This study examined how sampling frequency and time of day of contact impacted on response rates, response completeness, and response delay in repeated measures data collected via SMS. Eighty-five undergraduate students completed a six-item self-report questionnaire via SMS, in response to 20 SMS prompts sent on a random schedule. One group responded across 2 days, the other on a compressed schedule of 1 day. Overall, there was a high response rate. There was no significant difference in response rate, completeness, and delay of those responding across 1 or 2 days. Timing between prompts did not impact on response behavior. Responses were more likely to be complete if prompts were sent during the working day. The shortest time between prompts was 15 min, however, and use of an undergraduate sample limits generalizability. When conducting repeated measures sampling using SMS, researchers should be aware that more frequent sampling can be associated with poorer data quality, and should aim to collect data during the working day rather than mornings or evenings.

Background: Little is known about the effects of providing massage as a combination therapy (CT) with lumbopelvic stability training (LPST) in management of chronic nonspecific low back pain (CLBP) among elite female weight lifters. It is unclear whether massage therapy (MT) together with LPST has any additional clinical benefits for individuals with CLBP.Purpose: The current study compares the thera-peutic effects of CT against MT as a stand-alone intervention on pain intensity (PI), pain pressure threshold (PPT), tissue blood flow (TBF), and lumbopelvic stability (LPS) among elite weight lifters with CLBP.Setting: The study was conducted at the campus for National Olympic weight lifting training camp.Participants: A total of 16 professional female elite weight lifting athletes who were training for Olympic weight lifting competition participated in the study.Research Design: A within-subject, repeated measures, crossover, single-blinded, randomized allocation study.Intervention: The athletes were randomized into three sessions of CT and MT with a time interval of 24 hrs within sessions and a wash out period of four weeks between the sessions.Main Outcome Measures: The PI, PPT, TBF, and LPS were measured before and after each session repeatedly in both groups of intervention. The changes in the PI, PPT, TBF, and LPS were analyzed using repeated measures analysis of vari-ance (ANOVA).Results: The results showed that the CT signifi-cantly demonstrated greater effects in reducing pain perception (45%–51%), improving pain pressure threshold (15% up to 25%), and increas-ing tissue blood flow (131%–152%) than MT (p < .001).Conclusion: The combination therapy of mas-sage therapy and LPST is likely to provide more clinical benefits in terms of PI, PPT, and TBF when compared to massage as a stand-alone therapy among individuals with chronic nonspecific low back pain.

Context:Individuals with a history of low back pain (LBP) may present with decreased hip-abduction strength and increased trunk or gluteus maximus (GMax) fatigability. However, the effect of hip-abduction exercise on hip-muscle function has not been previously reported.Objective:To compare hip-abduction torque and muscle activation of the hip, thigh, and trunk between individuals with and without a history of LBP during repeated bouts of side-lying hip-abduction exercise.Design:Repeated measures.Setting:Clinical laboratory.Participants:12 individuals with a history of LBP and 12 controls.Intervention:Repeated 30-s hip-abduction contractions.Main Outcome Measures:Hip-abduction torque, normalized root-mean-squared (RMS) muscle activation, percent RMS muscle activation, and forward general linear regression.Results:Hip-abduction torque reduced in all participants as a result of exercise (1.57 ± 0.36 Nm/kg, 1.12 ± 0.36 Nm/kg; P < .001), but there were no group differences (F = 0.129, P = .723) or group-by-time interactions (F = 1.098, P = .358). All participants had increased GMax activation during the first bout of exercise (0.96 ± 1.00, 1.18 ± 1.03; P = .038). Individuals with a history of LBP had significantly greater GMax activation at multiple points during repeated exercise (P < .05) and a significantly lower percent of muscle activation for the GMax (P = .050) at the start of the third bout of exercise and for the biceps femoris (P = .039) at the end of exercise. The gluteal muscles best predicted hip-abduction torque in controls, while no consistent muscles were identified for individuals with a history of LBP.Conclusions:Hip-abduction torque decreased in all individuals after hip-abduction exercise, although individuals with a history of LBP had increased GMax activation during exercise. Gluteal muscle activity explained hip-abduction torque in healthy individuals but not in those with a history of LBP. Alterations in hip-muscle function may exist in individuals with a history of LBP.
