简要总结
The purpose of this study is; to compare the effects of interferential current therapy (IF) applied in addition to conventional physical therapy on pain, functional status and quality of life compared to pulsed electromagnetic field therapy (PEMF) in patients with chronic low back pain.
详细描述
The low back is the most common region for musculoskeletal pain. Many factors play a role in the etiology of low back pain. A certain etiological factor or pathophysiological mechanism cannot be found in 85-90% of the patients.
Approximately 80% of those living in industrialized countries experience low back pain in some part of their lives. 10% of low back pain becomes chronic. It is believed that 1% of workforce losses are due to low back pain. This type of pain often occurs when the back muscles, tendons and ligaments are exposed to stress or strain. Mechanical back pains are chronic pain that often affects the lower part of the spine and radiates to the gluteal region. Since daily activities such as leaning, turning, lifting, standing and sitting for a long time increase the pain, the intensity of the pain increases during the day.
Interferential current (IF) therapy is obtained from two medium frequency currents and is applied by delivering a low frequency current (for example 20 to 100 Hz) to the tissue.
Pulsed ElectroMagnetic Field (PEMF) therapy, which is among physical therapy methods, is frequently used in the treatment of knee, hip and spine osteoarthritis symptoms. It is thought that magnetic field therapy improves the oxygen utilization of the cells and the erythrocytes release more oxygen under the influence of the magnetic field, thus having a positive effect on the circulatory system

结局指标
主要结局
The Numerical Rating Scale (NRS)
时间窗: two weeks
It contains 11 digits that should be assigned according to the perceived pain intensity on a numerical scale. The participant chooses the number that best reflects his or her pain. In our study, the patients were informed that the '0' point was not pain at all, and the '10' point expressed unbearable pain.
次要结局
- Roland-Morris Disability Questionnaire(two weeks)
- Euroqol Quality Of Life Scale(two weeks)
