NCT00383682
Persistent pain occurs in 50-85 percent of patients who experience the amputation of an extremity. This study will compare the effectiveness of morphine and mexiletine to placebo in the treatment of postamputation pain. It is hypothesized that the effects of opioids and mexiletine on behavior and mental functioning in patients with postamputation pain are unlikely to be significant barriers to the clinical use of the drugs.
NCT00351208
The purpose of the study is to measure the efficacy of varying spinal cord stimulation frequencies and pulse-width settings on chronic pain management. The spinal cord stimulator settings that are most effective in chronic pain management hope to be revealed for the purposes of this study. In this double-blind study, both the patient and the staff will not be aware of the spinal cord stimulator settings for each patient each week. The representative that will set the settings each week will be blinded to the identity of each patient and will set the spinal cord stimulator from another room. While there are few papers that show the efficacy of spinal cord stimulation in treating chronic pain, there has yet to be a study performed that measures the role of stimulation frequency and pulse-widths. This study hopes to be the first.
