Filter by:Lower limb amputees suffer complete lack of sensory feedback of current available prostheses, which excludes the central nervous system from the correct sensory-motor integration. It causes serious problems as: falls due to unexpected perturbations, asymmetric walking, low mobility, higher power consumption, feeling the prosthesis as a foreign body, high cognitive burden, and phantom limb pain occurrence. Investigators will provide amputees with a prosthesis restoring sensory feedback and will assess its benefits on the users.
Patients with limb amputations experience the sensation of the missing extremity, which is sometimes coupled with a persistent and debilitating pain in the missing limb, a condition known as phantom limb pain (PLP). This study will test the use of virtual reality (VR) training as a possible treatment of PLP.
Stump and phantom pain after amputation are common, but the responsible mechanisms are still not clarified. It has been suggested that phantom limb pain can be reduced by regional anaesthesia and in several recent studies, pain was reduced following intrathecal and intraforaminal blocks. In this study, the investigators want to investigate if spontaneous and evoked pain in amputees will be relieved by regional nerve blocks involving the damaged nerves.
Investigating how neuropathic limb pain, including phantom limb pain or complex regional pain syndrome, is affected by virtual reality. While several studies have looked into virtual reality for treating this type of pain, few have used the latest immersive virtual reality hardware combined with motion control for an engaging virtual mirror therapy experience. The investigators are interested in studying the use of virtual reality as an alternative treatment option for these conditions.
This international, multi-center, double-blind, randomized, controlled clinical trial aims to evaluate the efficacy of Phantom Motor Execution (PME) and Phantom Motor Imagery (PMI) as treatments of Phantom Limb Pain (PLP). In PME, myoelectric pattern recognition (MPR) is used to predict motor volition and then use the decoded movements to control virtual and augmented reality environments (VR/AR), along with serious gaming (SG). The same device and VR/AR environments are used in PMI with the difference that subjects will imagine rather than execute phantom movements. Electromyography is used to monitor for no muscular activity in PMI.
Neuropathic pain is often a result of direct diseases of peripheral or central nervous system with an estimated prevalence of 8% of adults and this pain is associated with significant consequences because of longer symptom duration and severity than many of the other pain syndromes. Functional brain imaging has revealed that many regions of the brain are engaged by painful events, but specific areas such as the thalamus have been markedly implicated. The purpose of this study is to determine the feasibility and safety of MRI-guided focused ultrasound treatment using the ExAblate Transcranial System in patients suffering from Neuropathic pain. This treatment modality offers non-invasive precise treatment potential for these patients.
The goal of this pilot study is to assess the effectiveness of an electrical stimulation therapy option for the treatment of chronic phantom limb pain in upper or lower limb amputees. This therapy has been previously used for sports and joint injuries and is marketed for relaxation of muscle spasms, re-education of muscle action, prevention of disuse atrophy, increased local blood circulation, and maintaining or increasing range of motion. The investigators would like to explore the idea that physically exercising the muscles of the residual limb and increasing blood flow to the site of amputation through the promotion of motor contraction using electrical stimulation decreases chronic phantom limb pain.
The goals of this study are to provide sensory information to amputees and reduce phantom limb pain via electrical stimulation of the lumbar spinal cord and spinal nerves. The spinal nerves convey sensory information from peripheral nerves to higher order centers in the brain. These structures still remain intact after amputation and electrical stimulation of the dorsal spinal nerves in individuals with intact limbs and amputees has been demonstrated to generate paresthetic sensory percepts referred to portions of the distal limb. Further, there is recent evidence that careful modulation of stimulation parameters can convert paresthetic sensations to more naturalistic ones when stimulating peripheral nerves in amputees. However, it is currently unclear whether it is possible to achieve this same conversion when stimulating the spinal nerves, and if those naturalistic sensations can have positive effects on phantom limb pain. As a first step towards those goals, in this study, the investigators will quantify the sensations generated by electrical stimulation of the spinal nerves, study the relationship between stimulation parameters and the quality of those sensations, measure changes in control of a prosthesis with sensory stimulation, and quantify the effects of that stimulation on the perception of the phantom limb and any associated pain.
A randomized controlled clinical to examine the effect of mirror therapy on phantom pain and residual limb pain in patients with traumatic transtibial amputations in Cambodia. The study will be conducted with a semi-crossover design using self-rated pain and function as the main result variables.
This study will develop a virtual reality-based treatment for phantom limb pain among Veterans and test it against the most established behavioral therapy for phantom limb pain, mirror therapy.
