OBJECTIVE: To investigate the effect of motor cortex stimulation (MCS) on central poststroke pain (CPSP) and the outcome predictors associated with medium- to long-term results. MATERIALS AND METHODS: This is a retrospective review of 16 CPSP patients treated with MCS with a mean follow-up of 28.2 months. The pain intensity was assessed based on the visual analogue scale (VAS) before surgery and at various follow-up visits. An effective outcome was determined to be at least 40% pain relief...

Central poststroke pain (CPSP) is a severe type of neuropathic pain that can develop after stroke and is difficult to treat. Research into its underlying mechanisms and treatment options could benefit from a valid CPSP animal model. Nine different CPSP animal models have been published, but there are relatively few reports on successful reproductions of these models and so far only little advances in the understanding or the management of CPSP have been made relying on these models. In general, the construct validity (similarity in underlying mechanisms) of these CPSP animal models is relatively high, although this cannot be evaluated into depth because of lack of understanding the mechanisms through which thalamic stroke can lead to CPSP...

Electroacupuncture (EA) is reported to effectively relieve the central poststroke pain (CPSP). However, the underlying mechanism remains unclear. The present study investigated the detailed mechanisms of action of EA treatment at different frequencies for CPSP. A CPSP model was established with a single collagenase injection to the left ventral posterolateral nucleus of the thalamus. The EA-treated groups then received EA treatment at frequency of 2, 2/15, or 15 Hz for 30 min daily for five days. The pain-related behavioral responses, neuronal apoptosis, glial activation, and the expression of pain signal transmission-related factors (β-catenin, COX-2, and NK-1R) were assessed using behavioral tests, Nissl staining, TUNEL staining, and immunohistochemical staining, respectively...

Central poststroke pain (CPSP) is one of the most common central neuropathic pain syndromes seen after stroke. It is mainly related with vascular damage at certain brain territory and pain related to corresponding body areas. In the past, it was described as one of the definitive symptoms of thalamic lesion. However, recent findings suggest that it is not only seen after thalamic lesions but also seen after vascular lesions in any part of the central nervous system. Although there are certain hypotheses to explain physiopathologic mechanisms of CPSP, further evidence is needed...

Central poststroke pain is associated with specific somatosensory abnormalities, such as neuropathic pain syndrome. Although central poststroke pain is a serious condition, details pertaining to underlying mechanisms are not well established, making current standard treatments only partially effective. Here, we assessed the effects of tramadol, an analgesic drug mediated by opioid receptors, using a mouse model of global cerebral ischemia. Ischemia was induced by bilateral carotid artery occlusion (30 min) in male ddY mice...

OBJECTIVES: Spinal cord stimulation (SCS) is not typically recommended for the treatment of central poststroke pain (CPSP). We examined whether the pharmacological evaluation of CPSP is useful for selecting the candidates for SCS. MATERIALS AND METHODS: Changes in visual analog scale (VAS) scores for pain following pharmacological evaluation using morphine, thiopental, and ketamine were compared with those following SCS in 22 CPSP patients. RESULTS: Twelve of the 22 (54...

[Purpose] The aim of this study was to assess the effects of central poststroke pain on quality of life, functionality, and depression in stroke. [Subjects and Methods] Twenty-four patients with stroke having central poststroke pain (a mean age of 60.6±8.5 years; 14 males, 10 females; Group I) and 24 similar age-and gender-matched patients with stroke without central poststroke pain (Group II) were enrolled. Characteristics of pain were recorded in patients with stroke having central poststroke pain. The Visual Analogue Scale and Leeds Assessment of Neuropathic Symptoms and Signs pain scale were used to evaluate pain...

Chronic pain is common in patients with neurologic complications of a central nervous system insult such as stroke. The pain is most commonly musculoskeletal or related to obligatory overuse of neurologically unaffected limbs. However, neuropathic pain can result directly from the central nervous system injury. Impaired sensory discrimination can make it challenging to differentiate central neuropathic pain from other pain types or spasticity. Central neuropathic pain may also begin months to years after the injury, further obscuring recognition of its association with a past neurologic injury...

BACKGROUND: Spinal cord stimulation (SCS) is an established procedure for treatment of chronic neuropathic pain of peripheral origin. The efficacy of SCS in case of central poststroke pain (CPSP), especially thalamic pain, has not been adequately proven. OBJECTIVES: The efficacy of SCS as an extracranial neurostimulation method for the management of central pain syndrome was investigated. MATERIALS AND METHODS: In this study, relevant pharmacological and nonpharmacological measures for central pain management were reviewed...

BACKGROUND AND PURPOSE: Central poststroke pain is a chronic neuropathic disorder that follows a stroke. Current research on its management is limited, and no review has evaluated all therapies for central poststroke pain. METHODS: We conducted a systematic review of randomized controlled trials to evaluate therapies for central poststroke pain. We identified eligible trials, in any language, by systematic searches of AMED, CENTRAL, CINAHL, DARE, EMBASE, HealthSTAR, MEDLINE, and PsychINFO...

OBJECTIVE: Central poststroke pain is a serious problem for some patients after stroke. Repetitive transcranial magnetic stimulation (rTMS) has been reported to relieve poststroke pain but its efficacy is still controversial. We tested the possibility that rTMS, when applied once a week, would induce sustainable relief of poststroke pain. MATERIALS AND METHODS: Eighteen patients with central poststroke pain were included in this study. rTMS (10 trains of 10-sec 5 Hz-rTMS) was delivered over the primary motor cortex on the affected side...

Central poststroke pain (CPSP) is one of the most under-recognized consequences of stroke, occurring in up to 10% of patients, and is also one of the most difficult to treat. The condition characteristically develops after selective lesions to the spinothalamic system, most often to the ventral posterior thalamus. Here, we suggest that CPSP is best characterized as a disorder of brain network reorganization, and that this characterization offers insight into the inadequacy of most current pharmacological treatments...

Poststroke central pain (PSCP) can be a debilitating medication-refractory disorder. We report a single case where right unilateral ventral capsule/ventral striatum (VC/VS) deep brain stimulation was used to treat PSCP and inadvertently induced a smile without euphoria. The patient was a 69 year-old woman who had a stroke with resultant dysesthesia and allodynia in her left hemibody and also a painful left hemibody dystonia. In her case, VC/VS stimulation induced a smile phenomenon, but without a euphoric sensation...

Central poststroke pain (CPSP) is a central neuropathic pain condition caused by a cerebrovascular lesion affecting the central somatosensory nervous system. Once developed, CPSP is difficult to treat, so there is an interest in identifying stroke patients at risk for the development of CPSP. This study examined if sensory abnormalities, including evoked dysesthesia, allodynia, or hyperalgesia to static and dynamic touch, cold, and pinprick, at stroke onset are a predictor for the development of CPSP. Consecutive stroke patients were recruited from a large prospective study of poststroke pain in Aarhus, Denmark, between 2007 and 2008...

UNLABELLED: Central poststroke pain (CPSP) is caused by an encephalic vascular lesion of the somatosensory pathways and is commonly refractory to current pharmacologic treatments. Repetitive transcranial magnetic stimulation (rTMS) of the premotor cortex/dorsolateral prefrontal cortex (PMC/DLPFC) can change thermal pain threshold toward analgesia in healthy subjects and has analgesic effects in acute postoperative pain as well as in fibromyalgia patients. However, its effect on neuropathic pain and in CPSP, in particular, has not been assessed...

It has been proposed that cortical structural plasticity plays a crucial role in the emergence and maintenance of chronic pain. Various distinct pain syndromes have accordingly been linked to specific patterns of decreases in regional gray matter volume (GMV). However, it is not known whether central poststroke pain (CPSP) is also associated with cortical structural plasticity. To determine this, we employed T1-weighted magnetic resonance imaging at 3 T and voxel-based morphometry in 45 patients suffering from chronic subcortical sensory stroke with (n = 23) and without CPSP (n = 22), and healthy matched controls (n = 31)...

OBJECTIVE: To quantify changes in pain and somatosensory function in patients with central poststroke pain (CPSP) syndrome following five sessions of repetitive transcranial magnetic stimulation (rTMS). METHODS: Fourteen CPSP patients underwent MRI-guided TMS mapping to identify the motor hotspot for evoked responses from a muscle corresponding to a painful region (hand, N = 11, or distal leg, N = 3). Targeted rTMS consisting of 2000 stimuli/10 Hz each session was delivered over five sessions...
