This study aims to investigate the hemodynamic changes during dry cupping therapy (DCT) on low back pain. 50 patients with low back pain as experimental group and 50 healthy people as control group are treated by DCT. They will receive four consecutive WCT application in one month. Optical sensors were used to monitor the hemodynamic changes including oxyhemoglobin ([HbO2]), deoxy-hemoglobin ([Hb]) and the derived change in blood volume ([tHb]) in/surround the cupping sites during treatment. The investigators hope to interpret the curative effect of DCT from the perspective of modern hemodynamics.

Inclusion Criteria:

• Patients who have had non-specific low back pains at least 12 weeks now.
