Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The conventional intervention was administered to lumbosacral part by a physical therapist (one-on-one), including massage, ultrasound, TENS, low-level laser and exercise program (a sum of 10 sessions with all components of the intervention, 5 consecutive weekdays using a session attendance log). Massage (with deep stroking, wringing, friction, pulling and rolling techniques) and continuous ultrasound (frequency : 1 MHz, intensity : 1.5 W/cm2) lasted for 15 minutes and 5 minutes, respectively. Additionally, TENS was applied to lumbosacral part with four cutaneous electrodes for 20 minutes. Exercise program consisted of a strengthening part of the back and frontal abdominal muscles performed for 20 minutes with a set of 10 repetitions on each exercise (pelvic tilt, abdominal hollowing, knee to chest, oblique crunch, supine plank, bird and dog, cat and camel, lower abdominal and back extension exercises), as well as a stretching part of the hip flexors, hamstrings and lumbar extensors performed for 30 seconds on each muscle group. Last but not least, continuous low-level laser was applied with a contact method at four points over both sides of the spinal column for 80 seconds (830 nm, 120 m, 0-50000 Hz). During the treatment, patients could select to sit in a chair or lie down on a bed in the prone position in order to control for positional intolerance.

Quantitative variables were summarized in mean (Standard Deviation) and in median (interquartile range), while Qualitative variables were summarized in absolute and relative frequencies. Mann-Whitney test was used for the comparison of continuous variables be-tween two groups and Kruskall-Wallis test for the comparison of continuous var-iables among more than two groups. Spearman correlations coefficients were used to explore the association of two continuous variables. Spearman’s correla-tion coefficient values (rs) greater than 0.7, of 0.69–0.4, and of less than 0.39-0.1 were considered strong, moderate and weak correlations, respectively.Multiple linear regression analyses were conducted with dependent the health status, disa-bility and pain scales in a stepwise method (p for entry 0.05, p for removal 0.10). The factors that were included as independent variables in the model were socio-demographic (age, sex, marital and employment status, educational level), life-style (Body Mass Index, physical exercise), SSD, depression and anxiety as measured by the SSS-8 and HADS questionnaires, respectively. Adjusted regres-sion coefficients (ß) with standard errors (SE) were computed from the results of the linear regression analyses. Multiple linear regression analyses were conduct-ed after having the dependent variables logarithmically transformed. All report-ed p values are two-tailed. Wilcoxon signed tests were used for pre-post intervention comparisons of all under study-scales. Repeated measurements analysis of variance (ANOVA) was used to assess the variations watched closely in all under-study scales and their association with gender and BMI over the follow up period. Bonferroni correction was adopted in case of multiple testing in order to control for type I error. Repeated measurements analysis was conducted after logarithmic transformations of the scales. Cohen’s d was adopted in order to assess the clinical significance of the intervention effects, whose values of 0. 20, 0. 50 and 0. 80 are suggestive of small, medium and large effect sizes, accordingly. Quantitative variables were expressed as mean values (SD), while qualitative varia-bles were expressed as absolute and relative frequencies. Friedman’s test was used for score comparisons between pre-, post-treatment and 6 months measurements. Bonfer-roni correction was used in order to control for type I error. The effect size estimate Kendall's W value for Friedman test was computed via the formula W = ?2/N(K-1); where ?2 is the Friedman test statistic value; N is the sample size and K the number of measurements. [40] Kendalls uses the Cohen’s interpretation guidelines of 0.1 - 0.29 (small effect), 0.3 - 0.49 (moderate effect) and >= 0.5 (large effect). [41] Multiple linear regression analysis was used with dependent the scores at 6 months. The regression equation included terms for demographics and pre-treatment scores. Adjusted regres-sion coefficients (ß) with standard errors (SE) were computed from the results of the linear regression analyses. Logarithmic transformations of the dependent variables were used due to lack of normal distribution. All reported p values are two - tailed. Statistical analyses were completed using SPSS statistical software (version 22.0) and minimum level of significance was set at p < 0.05
