Background. Non-specific low back pain is a serious social problem. Most patients are unable to specify the particular event that caused the pain to appear. The typical treatment methods, i.e. pharmacotherapy and surgery, seldom lead to the desired results. One effective method of treating non-specific low back pain is physiotherapy, in which medical massage plays an important role. This is a therapeutic procedure based on theoretical and clinical research in medicine and related scientific fields. Material and methods. We studied 40 ambulatory patients, 31 men and 9 men, average age 47. The patients were evaluated using a 7-point scale of pain intensity and a patient evaluation chart, containing a comprehensive assessment of the musculo-skeletal system, including the functional status of other systems directly involved in motor function. Results. Before treatment, the patients’ subjective reports of pain intensity averaged 3.57 ± 1.1 points (moderately intense pain). After massage treatment, 77% of the patients (31 persons) reported no pain at all (0 points), and 23% (9 persons) reported minimal pain (1 point). Conclusions. The application of medical massage in this pathology significantly reduced the reported intensity of pain in all the patients we studied. Medical massage can be applied as an effective therapeutic procedure in managing pain for persons with non-specific low back pain.
