30 patients were randomly assigned to massage therapy. The procedures were performed for ten days, with weekend break. Manual massage of lumbar area was performed by certified massage therapist with the typical course of the procedure. The technique was consisted of stroking, kneading, grinding, patting and shaking. The procedure lasted twenty minutes.

30 patients were randomly assigned to Trabert current therapy. The Trabert current was administered by 143 frequency, time of 2 ms impulse, time of break 5 ms. The current was generated by Pulsotronic ST-6D device (ZAMED©). The electric pads were placed on the lumbar area, in the middle part of spine. The anode in the lower part, near to buttocks. The intensity of current was regulated between 15-25 mA. The time of procedure lasted fifteen minutes.

Trabert current is an interrupted direct current of low frequency (143 Hz) applied via medium sized electrodes supported on a thick moist viscose sponge. These electrodes are placed near the spinal column along the thoracolumbar region. The electrodes are separated from each other by a distance of 3-4 cms.The current is passed through electrodes placed on the body. The intensity of the current is gradually increased short of pain. The feeling should be a pronounced but a comfortable 'tingling' sensation ('comfortably strong'). By doing this, the optimum current strength specific to the patient is found. The intensity of the current is slowly increased in the first few minutes as patients get used to the sensation. It is thought that this current provides pain relief, reduces muscle spasm and increases blood flow.

Numerical raitng scale (NRS) are psychometric measuring instruments designed to document the characteristics of disease-related symptom severity in individual patients and use this to achieve a rapid (statistically measurable and reproducible) classification of symptom severity and disease control. NRS is10-point scale, where 0=no pain and 10=worst possible pain.

is an index derived from the Oswestry Low Back Pain Questionnaire used by clinicians and researchers to quantify disability for low back pain. The self-completed questionnaire contains ten topics concerning intensity of pain, lifting, ability to care for oneself, ability to walk, ability to sit, sexual function, ability to stand, social life, sleep quality, and ability to travel. Each topic category is followed by 6 statements describing different potential scenarios in the patient's life relating to the topic. The patient then checks the statement which most closely resembles their situation. Each question is scored on a scale of 0-5 with the first statement being zero and indicating the least amount of disability and the last statement is scored 5 indicating most severe disability. The scores for all questions answered are summed, then multiplied by two to obtain the index (range 0 to 100). Zero is equated with no disability and 100 is the maximum disability possible.

RMDQ is designed to assess self-rated physical disability caused by low back pain.widely. The RMDQ is scored by adding up the number of items checked by the patient. The score can therefore vary from 0 to 24. The questionnaire contains sentences that people have used to describe themselves when they suffer from back pain.
