Brief summary

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.

Design outcomes

Primary

Measure	Time frame	Description
Δ[HbO2]	all groups: up to 4 weeks	the concentration changes of oxyhemoglobin (higher alternation means better curative effect)
Δ[Hb]	all groups: up to 4 weeks	the concentration changes of deoxyhemoglobin (higher alternation means better curative effect)

Secondary

Measure	Time frame	Description
Δ[tHb]	all groups: up to 4 weeks	the concentration changes of blood volume (higher alternation means better curative effect)
NRS	experimental group: up to 4 weeks	Numeric Rating Scale for pain (lower score means better curative effect)
