The forebrain somatic sensory locus for input from sensors on the surface of an active prosthesis is an important component of the Brain Machine Interface. We now review the neuronal responses to controlled cutaneous stimuli and the sensations produced by Threshold Stimulation at Microampere current levels (TMIS) in such a locus, the human thalamic Ventral Caudal nucleus (Vc). The responses of these neurons to tactile stimuli mirror those for the corresponding class of tactile mechanoreceptor fiber in the peripheral nerve, and TMIS can evoke sensations like those produced by the stimuli that optimally activate each class...

The amputation of the lower limb is a crippling procedure, which impairs both physical and mental aspect of the patient's life and therefore, it is important to provide these patients with comprehensive health care. Patients and their families must change their lives and reorganize them, which is undoubtedly associated with a decrease in the quality of life. The aim of this study was to analyze various determinants of quality of life in patients after lower limb amputation and their impact on the physical, mental and social aspect of life...

BACKGROUND: Neuropathic pain, which is caused by a lesion or disease affecting the somatosensory system, may be central or peripheral in origin. Neuropathic pain often includes symptoms such as burning or shooting sensations, abnormal sensitivity to normally painless stimuli, or an increased sensitivity to normally painful stimuli. Neuropathic pain is a common symptom in many diseases of the nervous system. Opioid drugs, including morphine, are commonly used to treat neuropathic pain...

Cortex plasticity after hand amputation is considered harmful, causing phantom limb pain. A new study shows that cortical overtake can occur instead in a compensatory manner in people born with one hand, for multiple body parts used to overcome disability.

Previous work showed the existence of changes in the topographic organization within the somatosensory cortex (SI) in amputees with phantom limb pain, however, the link between nonpainful phantom sensations such as cramping or tingling or the percept of the limb and cortical changes is less clear. We used functional magnetic resonance imaging (fMRI) in a highly selective group of limb amputees who experienced inducible and reproducible nonpainful phantom sensations. A standardized procedure was used to locate body sites eliciting phantom sensations in each amputee...

The aim of this study was to evaluate the efficacy of eye movement desensitization and reprocessing (EMDR) on the phantom limb pain (PLP) of patients with amputations within a 24-month follow-up. This study was a randomized-controlled trial. A total of 60 patients with amputations were selected by a purposive sampling and patients were divided randomly into two experimental and control groups. Samples were assigned through randomized allocation. EMDR therapy was administered individually to the experimental group participants in 12 one-hour sessions over a 1-month period, In each session, the patient completed the Subjective Units of Distress Scale and a pain-rating scale before and after the intervention...

Neuropsychiatry had a profound impact on the life and work of one of the most influential French writers of the 20th century, Frédéric Sauser, better known by his pen name Blaise Cendrars (1887-1961). Cendrars, whose right writing hand was amputated after a battlefield wound in 1915, described with acuity his stump pain and phantom limb syndrome. He became a left-handed writer. Between 1956 and his death in 1961, he also suffered two strokes that progressively paralyzed his left side and greatly diminished his ability to speak...

The aim of this manuscript was to investigate the effectiveness of conservative therapy for phantom limb pain (PLP). In this systematic review, CINAHL, AMED, the Cochrane database of systematic reviews, PEDro, psychology and behavioral sciences collection, and MEDLINE were systematically searched for appropriate randomized controlled trials (RCTs). Selected papers were assessed for risk of bias, and evidence was graded using the GRADE approach. Twelve RCTs met initial inclusion/exclusion criteria, of which five were of sufficient quality for final inclusion...

BACKGROUND: Originally designed for prosthetic control, regenerative peripheral nerve interfaces (RPNIs) prevent neuroma formation by providing free muscle grafts as physiological targets for peripheral nerve ingrowth. We report the first series of patients undergoing RPNI implantation for treatment of symptomatic postamputation neuromas. METHODS: A retrospective case series of all amputees undergoing RPNI implantation for treatment of symptomatic neuromas between November 2013 and June 2015 is presented...

BACKGROUND: Dysvascular partial foot amputation (PFA) is a common sequel to advanced peripheral vascular disease. Helping inform difficult discussions between patients and practitioners about the level of PFA, or the decision to have a transtibial amputation (TTA) as an alternative, requires an understanding of the current research evidence on a wide range of topics including wound healing, reamputation, quality of life, mobility, functional ability, participation, pain and psychosocial outcomes, and mortality...

Using digital phantoms as an atlas compared to acquiring CT data for internal radionuclide dosimetry decreases patient overall radiation dose and reduces the required analysis effort and time for organ segmentation. The drawback is that the phantom may not match exactly with the patient. We assessed the effect of varying BMIs on dosimetry results for a bone pain palliation agent, (153)Sm-EDTMP. The simulation was done using the GATE Monte Carlo code. Female XCAT phantoms with the following different BMIs were employed: 18...

Research in myoelectric pattern recognition (MPR) for the prediction of motor volition has primarily focused on the upper limbs. Recent studies in the lower limbs have mainly concentrated on prosthetic control, while MPR for lower limb rehabilitation purposes has received little attention. In this work we investigated the viability of a MPR system for the prediction of four degrees of freedom controlled in a near natural or physiologically appropriate fashion. We explored three different electrode configurations for acquiring electromyographic (EMG) signals: two targeted (bipolar and monopolar) and one untargeted (electrodes equally spaced axially)...

Phantom limb pain in amputee patients is not well defined in the literature. Also there is still no clear information on the definition and treatment of phantom radicular pain, in which amputee patients also have radicular pain. This phenomenon, called phantom radiculitis or phantom radiculopathy, has been described in a limited number of cases. If a pathological condition to cause radicular pain is present in patients with amputee, the phantom pain\'s degree is increasing. Degenerative disc diseases are the most common cause of phantom radicular pain...

One of the most intriguing questions in neuroscience is to understand the mechanism of information transfer between different brain areas. Recently, network theory has gained traction and is at the forefront of providing a possible explanation to not only the mechanism of information transfer but also in the identification of different neuropathologies. The perception of a phantom ringing in the ear called tinnitus, similar to other neuropathologies, has been shown to be accompanied by aberrant functional connectivity between different brain areas...
