Filter by:During breast surgery, sensory nerves are cut which may lead to reduced sensation and pain. Surgical reinnervation techniques have been developed with the aim of improving postoperative sensation by preserving the nerves and connecting them to the nipple and areola. The investigators aim to compare postoperative sensation and patient reported outcomes in patients undergoing reinnervation versus those not undergoing reinnervation to determine if there is a difference. The investigators will investigate this in patients undergoing gender-affirming mastectomy, implant-based breast reconstruction and autologous breast reconstruction. The investigators will use various tools that measure sensation quantitatively.
The objective of this study is to develop a virtual rehabilitation system that can be used to effectively treat Phantom Limb Pain (PLP) within the research setting and for at-home use by individuals with upper and lower extremity amputation. We hypothesize that the system will improve PLP for individuals with upper or lower extremity amputation, as measured through with various outcome measures and questionnaires.
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.
