During the 23 years since this pain clinic was founded, 29, 458 patients have been treated here (about 385, 000 patient visits in total). In the earlier days, patients with whiplash injury (posttraumatic neck syndrome) were predominant. More males than females visited our clinic in those earlier days. Several years after this clinic opened, the percentage of female patients became higher (55% or more) than the percentage of male patients. Reflecting the social trend of an increase in the percentage of elderly people in the total population, the percentage of patients between 60 and 80 years of age has been increasing. Patients who visit this clinic live primarily in Osaka Prefecture. However, it is not uncommon that patients living in other prefectures of the Kinki district visit this clinic. Although patients visit our clinic because of various complaints, they often suffer from chronic, intractable complaints, such as low back pain, combined pain of the lower back and legs, and postherapuetic neuralgia. They often visit our clinic as a last resort for healing, after having consulted many other institutions. The duration of sickness among patients who visit our clinic is long (often over 5 years). Although the methods of treatment and the patients' responses vary, depending on their diseases, the combination of nerve block with acupuncture seems to be more effective on pain. We have utilized various techniques of acupuncture, including the in situ needle acupuncture, low-frequency therapy, SSP therapy, laser therapy and hyperthermia.
