Twelve patients with chronic renal diseases who underwent hemodialysis in the Oriental Medicine Outpatient Clinic of a general hospital were analyzed. The ratio of female to male patients was high, and patients' ages ranged from 31 to 71 years, with a mean age of 53.3 years. Many patients had been receiving hemodialysis for a relatively long time at a frequency of three times a week in most cases. They thus had to maintain a fixed posture for 4-5h per day several times a week. Underlying diseases were chronic glomerulonephritis, diabetic nephropathy, polycystic kidney and nephrosclerosis. Blood biochemical examination revealed high levels of BUN, CRE and UA, while K, Na, Ca and Pi electrolytes were almost normal. The drug therapy consisted mainly of urate biosynthesis inhibitors and electrolyte metabolism amelioraters. Symptoms resulting from long-term maintenance of a fixed posture and abnormalities in K, Na, Ca and Pi electrolytes included headache, stiffness in the neck and shoulder, pain in the arms, low back pain, pain in the legs and pain in the knee joint. Acupuncture was slightly effective or better in 73.1% of the patients, and none of them showed aggravation.
