The study consisted of 148 subjects (age range= 20-60 years) with low back pain. These subjects were randomized into 2 treatment groups: one group was treated with interferential therapy using a standard Galva electrotherapy electrotherapy /elec·tro·ther·a·py/ (-ther´ah-pe) treatment of disease by means of electricity. e·lec·tro·ther·a·py n.

None of the subjects had previous spinal surgery, any significant medical conditions, or any spinal disorders that appeared on plain radiographs (eg, spondylolysis). All subjects received six 10-minute treatment sessions over a period of 14 to 21 days except for 3 subjects who only received 4 treatments. Subjects filled out an Oswestry Disability Index (ODI) and a visual analog scale (VAS vas (vas) pl. va´ sa [L.] vessel.va´sal vas aber´rans 1. a blind tubule sometimes connected with the epididymis; a vestigial mesonephric tubule. 2. ) that measured pain (0=no pain, 100=unbearable pain)immediately before and after treatment and at a 3-month follow-up. Ten subjects dropped out of the study (3 in the traction group and 7 in the interferential group) during the intervention, and another 10 subjects were lost during the 3-month follow-up (3 subjects in the traction group and 7 subjects in the interferential group). Statistical analysis was done using StatView 3 software. The ODI's final score was expressed as a percentage. Two non-parametric methods were used: the Mann-Whitney U test Mann-Whitney U test, n.pr See test, Mann-Whitney U. for unpaired data and the Wilcoxon signed rank test. The mean ODI score was 30 for both groups. After treatment, this score dropped to 25 for both groups; at the 3-month follow-up, the mean ODI score was 21 for the interferential therapy group and 22 for the motorized lumbar and traction group. The mean VAS scores before treatment were 50 (interferential therapy) and 51 (motorized lumbar traction and massage). These scores dropped to 46 and 44 after therapy and 42 and 39 at follow-up, respectively. On the ODI scores, a significant difference existed in the median score for the periods between the 3 interview times, but no significant difference existed between the 2 treatment groups at any of the 3 interview times. For the VAS pain scores, significant differences existed before treatment, after treatment (for lumbar traction only), and at 3 months, but no significant differences existed between the groups. The authors concluded that, in this study, improvement may be explained because of one or more of the following reasons: (1) neither treatment did any good or harm and improvements were due to the natural history of low back pain, (2) some part of the improvement was explained by a placebo effect placebo effect n. A beneficial effect in a patient following a particular treatment that arises from the patient's expectations concerning the treatment rather than from the treatment itself. that acted similarly in both groups, and (3) some part of the treatment was effective.
