Informed consent was obtained from all participants. We use two groups to investigate the effects of the tangentor on the low back pain.~The patients presenting at the rheumatology inpatient clinics were enrolled without into the treatment and control groups.~Patients receiving Transcutaneous Electrical Nerve Stimulation + underwater massage + spine gymnastics~In the controll group the Patients receiving Transcutaneous Electrical Nerve Stimulation + spine gymnastics~Underwater jet massage (Tangentor) would be performed in a tub developed for this purpose, where the water temperature: 33-35 ° C. The treatments lasting from 15 atm and 15 cm for 15 minutes.~The water temperature is precisely measured by a built-in thermometer. Pressure is controlled by a manometer.~They take a minimum of 10 treatments for approx. under 2 weeks.~The back massage position is, that the patient lying on their side, hip and knees are slightly bent and the head and neck rest on a support.~After the massage the client should rest for about 30minutes.~Patients participated in two visits, for the first time before the study, right after the therapy treatments.~During the study, all participants received the usual or necessary medications. On a Visual Analogue Scale (VAS) patients indicated degree of pain on a scale from 0 to 100 mm for the past week. VAS scores were expressed in millimetres (zero point-no pain; endpoint-intolerable pain). Patients recorded on the VAS scale the level of low back pain at rest as well as during activity. Functional disability was assessed by using the Oswestry Disability Index (ODI).~Furthermore, there was a questionnaire on the quality of life, known as the EuroQol Five Dimensions Questionnaire (EQ-5D-5L).
Underwater massage is the more modern variety of massages otherwise known as tangentor, where the temperature of the water of the treatment tub and the mechanical effect of the water jet is utilised. It is typical of chronic low back pain that, after the first painful episode, is repeated at 44-78% of patients.~Our goals are the followings:~Is the beneficial effect of a Underwater massage therapy addition to a complex physiotherapy comparable to a control group with respect to clinical parameters?~How much does the quality of life change in an initial state and how much is it in comparison with the control group?
