Filter by:Mirror therapy will consist of observing the unaffected limb reflected in a mirror positioned in the midline to block the view of the affected limb. All therapy sessions will be supervised by a physical therapist with the exception of weekends when the patients will continue therapy on an independent basis. In an effort to objectively demonstrate cortical reorganization associated with mirror therapy, patients can elect to participate in a functional MRI (fMRI) portion of the study. The fMRI would be evaluated prior to initiating the experimental or control therapy (Due to the sensitive timeline in this population and its effect on recruitment, we have amended the protocol to allow recruitment and enrollment to take place even if the timeline does not allow for the fMRI to be executed 2 weeks prior to amputation. Though this would be ideal, we will accept subjects that are only available for day before amputation scans), just before the operative procedure, at four weeks post-operation and then again at one year. All subjects will be evaluated at 4 weeks, 8 weeks (functional physical therapy (PT) tests only) 12 weeks, and 12 months postoperatively to determine 1) the incidence, severity and functional impact of phantom limb pain 2)the ability to meet various specialists' endpoints, to include participation in physical therapy, and 3) overall quality of life which the patients can describe subjectively. This therapy could have a dramatic impact on the long term prognosis of amputees whether due to trauma, metabolic conditions, tumor, or peripheral vascular disease. This protocol will include performing fMRIs on a cohort of healthy, active duty, age matched, male personnel to create reference data to compare the fMRI data of study participants.
Phantom limb pain (PLP) is as painful sensations located to the missing limb and classified as neuropathic pain. In the United States, an estimated 1.7 million patients have undergone limb amputation, and 60% to 80% of these patients develop PLP (1-2) and it is usually resistant to a wide variety of treatments (1-4). Three factors may contribute to the development of persistent, post-amputation PLP by inducing central sensitization at different times relative to surgery: pre-amputation pain, noxious intraoperative stimuli, and acute postoperative pain (5-7). Investigators hypothesis that pre-amputation period could be important in eliminating Phantom Limb Pain (PLP) in the patients in whom cortical reorganization is not yet established. The reduction of pre-operative pain and prevention of formation of pain memories may eliminate development of PLP by using dual networks treatment strategy. This Phase III, randomized, double-blind, placebo-controlled study is designed to evaluate the efficacy of pre-operative pregabalin (lyrica) and ketamine in eliminating phantom limb pain in patients undergoing lower limb amputation.
