The goal of this clinical trial is to learn if Electroacupuncture combined with Dry cupping therapy works to treat back pain due to lumbar spondylosis in the qi stagnation and blood stasis pattern. I

The main questions it aims to answer are:

• Does Electroacupuncture combined with Dry cupping therapy reduces pain on Visual Analog Scale (VAS) of patients suffered from back pain due to lumbar spondylosis in the qi stagnation and blood stasis pattern?
• Dose Electroacupuncture combined with Dry cupping therapy improving the daily activities on Oswestry Disability index (ODI) of patients suffered from back pain due to lumbar spondylosis in the qi stagnation and blood stasis pattern?
• What medical problems do participants have when taking Electroacupuncture combined with Dry cupping therapy ? Researchers will compare dry cupping to a sham dry cupping (a sham cupping device was developed by establishing a small hole to reduce the negative pressure after suction such that inner pressure could not be maintained in the cup) to see if dry cupping therapy works to treat back pain due to lumbar spondylosis in the qi stagnation and blood stasis pattern.

Patients with back pain due to lumbar spondylosis in the qi stagnation and blood stasis pattern will be registered for this study. They will be treated with a combination of Electroacupuncture combined with Dry cupping therapy.

The intervention period is two weeks. Electronic acupuncture will be performed once a day for 2 weeks. Dry cupping therapy will be performed every 4 days for 2 weeks. Data on the Visual Analog Scale (VAS), Oswestry Disability index (ODI), and side effects of Electroacupuncture and Dry cuppingwill be recorded before the study and weekly for 2 weeks.
