Brief Summary
The purpose of this study is to assess the efficacy of electroacupuncture (EA) on pain control, perception of pain, plasma cortisol and beta-endorphins levels, patient-perceived quality of life and use of pain medications, in people with chronic knee pain.

Study Arms (2)
placebo/sham acupuncture
SHAM COMPARATORThere are different types of controls used in acupuncture trials. We used the control described as sham and by some as minimal acupuncture. This group had the same schedule as the electro-acupuncture group. Sham acupuncture was administered, with the same duration and frequency and by the same specialist who performed the non-sham acupuncture. Retractable needles were placed into small adhesive cylinders, so that the needles were supported but did not perforate the skin. The acupuncturist placed the needles at the same points as the non-sham group and used the same pairs of electrodes to simulate the electrical connection.
Electroacupuncture
ACTIVE COMPARATORThe electro-acupuncture device was a biphasic pulse generator. It was used with maximum tolerable intensity of current and a frequency of 3 Hz. The points were selected according to the Traditional Chinese Medicine meridian theory to treat knee pain. The points selected were local points St 34, St 35, St 36,Liv 8, Sp 10. One distal point St 44.A total of six needles were inserted into each leg by the acupuncturist (the out come measures were not specifically targeted to whether the patient had one or both knees involved). All patients belonging to this group experienced a De Qi sensation, which is a tingling and numbness sensation upon needling of specific points.
Interventions
Electro acupuncture is a relatively new method of treatment in Chinese Medicine. Just as in a regular acupuncture treatment, needles are inserted into acupuncture points but small crocodile clips are then attached to the ends of needles to connect them to an electro-acupuncture device. In traditional acupuncture the inserted needles are manually vibrated to induce a response whilst in electro-acupuncture the bi-phasic current results in a constant (controlled) vibration of the needles and a direct electrical stimulation. The device allows the practitioner to adjust the frequency and intensity of the electric stimulation in a consistent manner which is not operator dependant.
Eligibility Criteria
You may qualify if:
- Patients of either sex with primary osteoarthritis of one or both knees fulfilling diagnostic criteria for osteoarthritis knee laid down by American College of Rheumatology.
- Patients also had to have a Kellgren-Lawrence (radiologic criterion) score of at least 2 and chronic pain in the knee joint for more than 3 months.
You may not qualify if:
- The patients with secondary osteoarthritis of knees
- Associated systemic arthropathies, e.g. rheumatoid arthritis and gout
- Patients on steroids
- Disease modifying drugs, e.g. methotrexate and azathioprine
- Patients with recent trauma in the area of acupuncture
- History of intra articular injection of steroid within last two months
- Patients missing two or more sessions of electro-acupuncture consecutively were excluded from the study
