Pain is the most popular complaint since the appearance of the human on earth, a very unpleasant feeling sometimes difficult to be treated. Therefore, we have many patients who complain of
pain in our hospitals or clinics. When a patient with
pain visits our institution, first of all, we must evaluate the grade of
pain, and then start to treat the
pain of the patient. Of course, we have many devices available to treat the patient with
pain. In the following special articles, device for evaluation of
pain, spinal stimulation device, device for electrical current
therapy (ECT),
LASER device for chronic and
acute pain, epiduroscopy for
lumbago, as well as disposable
infusion pump for
postoperative pain and
cancer pain are described. The mechanism of
pain may be understood by patients themselves. However, devices in these articles are very useful for the treatment of
pain, especially
intractable pain. I feel very happy if these articles contribute greatly for the treatment of patients with
pain.
