Prefrontal engrams of long-term fear memory perpetuate pain perception

Johannes Gräff

A painful episode can lead to a life-long increase in an individual's experience of pain. Fearful anticipation of imminent pain could play a role in this phenomenon, but the neurobiological underpinnings are unclear because fear can both suppress and enhan ...

Targeted dorsal root entry zone stimulation alleviates pain due to meralgia paresthetica

Grégoire Courtine, Jocelyne Bloch, Léonie Asboth, Robin Jonathan Demesmaeker, Jimmy James Ravier, Nicolas Hankov, Viviana Aureli

Objective. Meralgia paresthetica (MP) is a mononeuropathy of the exclusively sensory lateral femoral cutaneous nerve (LFCN) that is difficult to treat with conservative treatments. Afferents from the LFCN enter the spinal cord through the dorsal root entry ...

Scrambler Therapy for Chronic Pain after Burns and Its Effect on the Cerebral Pain Network: A Prospective, Double-Blinded, Randomized Controlled Trial

Chang-Hyun Park

Chronic pain is common after burn injuries, and post-burn neuropathic pain is the most important complication that is difficult to treat. Scrambler therapy (ST) is a non-invasive modality that uses patient-specific electrocutaneous nerve stimulation and is ...

During capsaicin-induced central sensitization, brush allodynia is associated with baseline warmth sensitivity, whereas mechanical hyperalgesia is associated with painful mechanical sensibility, anxiety and somatization

Anne-Christine Schmid

Background Mechanical hyperalgesia and allodynia incidence varies considerably amongst neuropathic pain patients. This study explored whether sensory or psychological factors associate with mechanical hyperalgesia and brush allodynia in a human experimenta ...

Overcorrected Implants for Total Shoulder Arthroplasty

Yasmine Boulanaache

Glenohumeral osteoarthritis is a degenerative shoulder joint disease, which causes the breakdown of articular cartilage and bone. People affected by this disease suffer from severe pain and eventually reduced mobility and poor life quality. This disease is ...

The outcomes of a second and third Gamma Knife radiosurgery for recurrent essential glossopharyngeal neuralgia

Constantin Tuleasca

Introduction Gamma Knife radiosurgery (GKR) is a minimally invasive surgical option for drug-resistant essential glossopharyngeal neuralgia (GPN). The authors reviewed pain outcomes and complications in GPN patients who underwent a second or a third GKR fo ...

Central and peripheral mechanisms: a multimodal approach to understanding and restoring human motor control

Nawal Noëlle Kinany

All human actions involve motor control. Even the simplest movement requires the coordinated recruitment of many muscles, orchestrated by neuronal circuits in the brain and the spinal cord. As a consequence, lesions affecting the central nervous system, su ...

Enhancing analgesic spinal cord stimulation for chronic pain with personalized immersive virtual reality

Olaf Blanke, Bruno Herbelin, Andrea Serino, Giulio Rognini, Marco Solcà, Robin Mange, Pavo Orepic

Spinal cord stimulation (SCS) is an approved treatment for truncal and limb neuropathic pain. However, pain relief is often suboptimal and SCS efficacy may reduce over time, requiring sometimes the addition of other pain therapies, stimulator revision, or ...

Cognitive neuroprosthetics for investigating and restoring body perception

Marco Solcà

Our brain constantly receives and integrates a flow of multisensory bodily inputs that are responsible for the way our body is represented and consciously experienced. However, in some pathological conditions, patients might experience altered perceptions ...

Microchannel-based technologies for nerve interfacing

Sandra Gribi

Biomedical technologies in neuroprosthetics are made to restore or replace functions from the nervous system, as well as alleviate pathological conditions. Peripheral nerve interfaces use neuromodulatory techniques to inhibit pain or depression, prevent ep ...

Heartbeat-enhanced immersive virtual reality to treat complex regional pain syndrome

Olaf Blanke, Bruno Herbelin, Andrea Serino, Roberta Ronchi, Javier Bello Ruiz, Marco Solcà, Thomas Schmidlin

OBJECTIVES: To develop and test a new immersive digital technology for complex regional pain syndrome (CRPS) that combines principles from mirror therapy and immersive virtual reality and the latest research from multisensory body processing. METHODS: In t ...

Brain-controlled modulation of spinal circuits improves recovery from spinal cord injury

Silvestro Micera, Grégoire Courtine, Marco Bonizzato, Natalia Pavlova, Galyna Pidpruzhnykova

The delivery of brain-controlled neuromodulation therapies during motor rehabilitation may augment recovery from neurological disorders. To test this hypothesis, we conceived a brain-controlled neuromodulation therapy that combines the technical and practi ...

Virtual reality improves embodiment and neuropathic pain caused by spinal cord injury

Olaf Blanke, Marco Solcà, Roberta Ronchi, Estelle Palluel, Polona Pozeg

Objective: To investigate changes in body ownership and chronic neuropathic pain in patients with spinal cord injury (SCI) using multisensory own body illusions and virtual reality (VR). Methods: Twenty patients with SCI with paraplegia and 20 healthy cont ...

Motor imagery in spinal cord injured people is modulated by somatotopic coding, perspective taking, and post-lesional chronic pain

Polona Pozeg

Motor imagery (MI) allows one to mentally represent an action without necessarily performing it. Importantly, however, MI is profoundly influenced by the ability to actually execute actions, as demonstrated by the impairment of this ability as a consequenc ...

Chronic low back pain patients walk with locally altered spinal kinematics

Julien Favre, Brigitte Jolles-Haeberli

Various studies have reported alterations of spinal kinematics in patients with chronic low back pain (CLBP) during gait. However, while recent findings stressed the importance of multi-segment analysis, most of prior gait studies modelled the lumbar spine ...

Quantifying dimensions of physical behavior in chronic pain conditions

Kamiar Aminian, Anisoara Ionescu

Background: Chronic pain, defined as persistent or recurrent pain lasting longer than 3 months, is a frequent condition affecting an important percent of population worldwide. Pain chronicity can be caused by many different factors and is a frequent compon ...

Multi-segment analysis of spinal kinematics during sit-to-stand in patients with chronic low back pain

Julien Favre

While alterations in spinal kinematics have been frequently reported in patients with chronic low back pain (CLBP), a better characterization of the kinematics during functional activities is needed to improve our understanding and therapeutic solutions fo ...

Nano Fibrillated Cellulose Based Composite Hydrogels for an Injectable Intervertebral Disc Implant

Azadeh Khoushabi

Replacing the gel-like central part of the intervertebral disc (IVD), so-called nucleus pulposus (NP), via a minimally invasive surgery is one of the most recent approaches in the lower back pain treatments. An appropriate biomaterial for NP replacement (N ...

Resonance Energy Transfer Relates the Gas-Phase Structure and Pharmacological Activity of Opioid Peptides

Oleg Boyarkine, Vladimir Kopysov

Enkephalins are efficient pain-relief drugs that bind to transmembrane opioid receptors. One key structural param- eter that governs the pharmacological activity of these opioid peptides and is typically determined from condensed-phase structures is the di ...

Size and Viewpoint of an Embodied Virtual Body Affect the Processing of Painful Stimuli

Olaf Blanke, Joan Llobera Mahy

Looking at one's own body might induce visual analgesia. However, the cognitive and physiological mechanisms underlying such visual analgesia are unknown. Because body and pain representations in the brain are multisensory, and have been reported to partia ...
