Interventional
Description of intervention(s) / exposure
The objective of this study is to assess the effectiveness of radiofrequency therapy and to
compare real procedures to sham procedures in the treatment of low back pain.
Participants will be randomised to receive radiofrequency or placebo therapy,
Patients from group A will receive a radiofrequency therapy that includes application within low back (the active parameters: frequency 448 kHz, energy level 12-20 W, session duration 15 minutes).
Patients from group B will receive a sham therapy which voided of active components by applying a special applicator cap, which absorbed energy and limited its propagation to the
human tissues (session duration 15 minutes).
During the therapy, there will be constant supervision of the patient and observation of the patient for 15 minutes after the intervention.
Each patient from two groups will have 10 sessions (twice a week) within 5 weeks. The
intervention will occur in the clinician's office and be administered by certified physiotherapist and naturopathic practitioner.
In addition, all patients will be supplemented with physical exercises performed throughout the therapy period. A single exercise series will last 45 minutes daily and will be carried out five times a week (Monday to Friday) for 5 weeks.
Stabilization training will include:
- Techniques for the relaxation of the myofascial system on erector spinae muscle,
- Techniques for activating the neutral position of the lumbo-pelvic-hip complex and deep
muscles,
- Stimulation of proper breathing and correct activation of the transverse abdominal muscle,
- Coordination of superficial and deep muscles activation,
- Postural and dynamic training.
The physical exercises will occur "one-on-one" method in the gym part of clinician's office and be administered by a certified athletic therapist. The training will be with the participants' intensity of 65-75% maximal heart rate (to monitor the application of exercises and the participants' status; the therapist observation diary will be kept).

Comparator / control treatment
Patients from control group will receive a sham therapy which voided of active components by applying a special applicator cap, which absorbed energy and limited its propagation to the human tissues (session duration 15 minutes).
Each patient from control group will have 10 sessions (twice a week) within 5 weeks. The
intervention will occur in the clinician's office and be administered by certified physiotherapist and naturopathic practitioner.
Will be treated with kinesitherapy, a single exercise series will last 45 minutes daily and will be carried out five times a week (Monday to Friday), the same as in the study group.

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Participants will be randomly allocated to the groups. Computer-generated random numbers will be sealed in sequentially numbered envelopes, and the group allocation be independent of the time and person delivering the treatment. The physician (research coordinator) who will allocate the subjects to groups have envelopes, each containing a piece of paper marked with either group A or B The physician will select and open an envelope in the presence of a physiotherapist to see the symbol and then direct the patient to the corresponding group.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Simple randomisation using computer and numbered envelopes
Masking / blinding

Statistical methods / analysis
Statistical analysis
Statistical analysis was performed using Statistica 13 (TIBCO, Inc., USA). For measurable variables, arithmetic means, medians, standard deviations, quartiles and the range of variability (extreme values) were calculated. Frequencies were calculated for qualitative variables (results are given in percentages). Quantitative variables were checked with the Shapiro-Wilk test to determine the type of distribution. Comparison of qualitative variables between groups was made using the chi-square test (?2). Intragroup comparison between results was performed using Friedman's analysis of variance and post-hoc test (Dunn's test). Finally, the comparison of results between the study group and placebo was assessed using the Mann-Whitney U-test. The level of a=0.05 was used for all comparisons.
