Dissecting central post-stroke pain: a controlled symptom-psychophysical characterization. Brain Commun 2022; 4:fcac090. [PMID: 35528229 PMCID: PMC9070496 DOI: 10.1093/braincomms/fcac090] [Citation(s) in RCA: 10] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/19/2021] [Revised: 12/21/2021] [Accepted: 03/31/2022] [Indexed: 11/14/2022] Open
Abstract
Central post-stroke pain affects up to 12% of stroke survivors and is notoriously refractory to treatment. However, stroke patients often suffer from other types of pain of non-neuropathic nature (musculoskeletal, inflammatory, complex regional) and no head-to-head comparison of their respective clinical and somatosensory profiles has been performed so far. We compared 39 patients with definite central neuropathic post-stroke pain with two matched control groups: 32 patients with exclusively non-neuropathic pain developed after stroke and 31 stroke patients not complaining of pain. Patients underwent deep phenotyping via a comprehensive assessment including clinical exam, questionnaires and quantitative sensory testing to dissect central post-stroke pain from chronic pain in general and stroke. While central post-stroke pain was mostly located in the face and limbs, non-neuropathic pain was predominantly axial and located in neck, shoulders and knees (P < 0.05). Neuropathic Pain Symptom Inventory clusters burning (82.1%, n = 32, P < 0.001), tingling (66.7%, n = 26, P < 0.001) and evoked by cold (64.1%, n = 25, P < 0.001) occurred more frequently in central post-stroke pain. Hyperpathia, thermal and mechanical allodynia also occurred more commonly in this group (P < 0.001), which also presented higher levels of deafferentation (P < 0.012) with more asymmetric cold and warm detection thresholds compared with controls. In particular, cold hypoesthesia (considered when the threshold of the affected side was <41% of the contralateral threshold) odds ratio (OR) was 12 (95% CI: 3.8-41.6) for neuropathic pain. Additionally, cold detection threshold/warm detection threshold ratio correlated with the presence of neuropathic pain (ρ = -0.4, P < 0.001). Correlations were found between specific neuropathic pain symptom clusters and quantitative sensory testing: paroxysmal pain with cold (ρ = -0.4; P = 0.008) and heat pain thresholds (ρ = 0.5; P = 0.003), burning pain with mechanical detection (ρ = -0.4; P = 0.015) and mechanical pain thresholds (ρ = -0.4, P < 0.013), evoked pain with mechanical pain threshold (ρ = -0.3; P = 0.047). Logistic regression showed that the combination of cold hypoesthesia on quantitative sensory testing, the Neuropathic Pain Symptom Inventory, and the allodynia intensity on bedside examination explained 77% of the occurrence of neuropathic pain. These findings provide insights into the clinical-psychophysics relationships in central post-stroke pain and may assist more precise distinction of neuropathic from non-neuropathic post-stroke pain in clinical practice and in future trials.

Abstract
Chronic pain is a maladaptive neurological disease that remains a major health problem. A deepening of our knowledge on mechanisms that cause pain is a prerequisite to developing novel treatments. A large variety of animal models of pain has been developed that recapitulate the diverse symptoms of different pain pathologies. These models reproduce different pain phenotypes and remain necessary to examine the multidimensional aspects of pain and understand the cellular and molecular basis underlying pain conditions. In this review, we propose an overview of animal models, from simple organisms to rodents and non-human primates and the specific traits of pain pathologies they model. We present the main behavioral tests for assessing pain and investing the underpinning mechanisms of chronic pathological pain. The validity of animal models is analysed based on their ability to mimic human clinical diseases and to predict treatment outcomes. Refine characterization of pathological phenotypes also requires to consider pain globally using specific procedures dedicated to study emotional comorbidities of pain. We discuss the limitations of pain models when research findings fail to be translated from animal models to human clinics. But we also point to some recent successes in analgesic drug development that highlight strategies for improving the predictive validity of animal models of pain. Finally, we emphasize the importance of using assortments of preclinical pain models to identify pain subtype mechanisms, and to foster the development of better analgesics.

Abstract
BACKGROUND Chronic pain is common and significantly impacts on the lives of persons with multiple sclerosis (pwMS). Various types of non-pharmacological interventions are widely used, both in hospital and ambulatory/mobility settings to improve pain control in pwMS, but the effectiveness and safety of many non-pharmacological modalities is still unknown. OBJECTIVES This review aimed to investigate the effectiveness and safety of non-pharmacological therapies for the management of chronic pain in pwMS. Specific questions to be addressed by this review include the following.Are non-pharmacological interventions (unidisciplinary and/or multidisciplinary rehabilitation) effective in reducing chronic pain in pwMS?What type of non-pharmacological interventions (unidisciplinary and/or multidisciplinary rehabilitation) are effective (least and most effective) and in what setting, in reducing chronic pain in pwMS? SEARCH METHODS A literature search was performed using the specialised register of the Cochrane MS and Rare Diseases of the Central Nervous System Review Group, using the Cochrane MS Group Trials Register which contains CENTRAL, MEDLINE, Embase, CINAHL, LILACUS, Clinical trials.gov and the World Health Organization International Clinical Trials Registry Platform on 10 December 2017. Handsearching of relevant journals and screening of reference lists of relevant studies was carried out. SELECTION CRITERIA All published randomised controlled trials (RCTs)and cross-over studies that compared non-pharmacological therapies with a control intervention for managing chronic pain in pwMS were included. Clinical controlled trials (CCTs) were eligible for inclusion. DATA COLLECTION AND ANALYSIS All three review authors independently selected studies, extracted data and assessed the methodological quality of the studies using the Grades of Recommendation, Assessment, Development and Evaluation (GRADE) tool for best-evidence synthesis. Pooling data for meta-analysis was not possible due to methodological, clinical and statistically heterogeneity of the included studies. MAIN RESULTS Overall, 10 RCTs with 565 participants which investigated different non-pharmacological interventions for the management of chronic pain in MS fulfilled the review inclusion criteria. The non-pharmacological interventions evaluated included: transcutaneous electrical nerve stimulation (TENS), psychotherapy (telephone self-management, hypnosis and electroencephalogram (EEG) biofeedback), transcranial random noise stimulation (tRNS), transcranial direct stimulation (tDCS), hydrotherapy (Ai Chi) and reflexology.There is very low-level evidence for the use of non-pharmacological interventions for chronic pain such as TENS, Ai Chi, tDCS, tRNS, telephone-delivered self-management program, EEG biofeedback and reflexology in pain intensity in pwMS. Although there were improved changes in pain scores and secondary outcomes (such as fatigue, psychological symptoms, spasm in some interventions), these were limited by methodological biases within the studies. AUTHORS' CONCLUSIONS Despite the use of a wide range of non-pharmacological interventions for the treatment of chronic pain in pwMS, the evidence for these interventions is still limited or insufficient, or both. More studies with robust methodology and greater numbers of participants are needed to justify the effect of these interventions for the management of chronic pain in pwMS.

Abstract
Study design: Case Report. Purpose: Stroke is the most common cause of long-term disability. Dysesthesia, an unpleasant sensory disturbance, is common following thalamic stroke and evidence-based interventions for this impairment are limited. The purpose of this case report was to describe a decrease in dysesthesia following manual therapy intervention in a patient with history of right lacunar thalamic stroke. Case description: A 66-year-old female presented with tingling and dysesthesia in left hemisensory distribution including left trunk and upper/lower extremities, limiting function. Decreased left shoulder active range of motion, positive sensory symptoms but no sensory loss in light touch was found. She denied pain and moderate shoulder muscular weakness was demonstrated. Laterality testing revealed right/left limb discrimination deficits and neglect-like symptoms were reported. Passive accessory joint motion assessment of glenohumeral and thoracic spine revealed hypomobility and provoked dysesthesia. Interventions included passive oscillatory joint mobilization of glenohumeral joint, thoracic spine, ribs and shoulder strengthening. Results: After six sessions, shoulder function, active range of motion, strength improved and dysesthesia decreased. Global Rating of Change Scale was +5 and QuickDASH score decreased from 45% to 22% disability. Laterality testing was unchanged. Conclusion: Manual therapy may be a beneficial intervention in management of thalamic stroke-related dysesthesia. Implications for Rehabilitation While pain is common following thalamic stroke, patients may present with chronic paresthesia or dysesthesia, often in a hemisensory distribution. Passive movement may promote inhibition of hyperexcitable cortical pathways, which may diminish aberrant sensations. Passive oscillatory manual therapy may be an effective way to treat sensory disturbances such as paresthesias or dysesthesia.

THE JOURNAL OF PAIN 2018; 19:727.e1-727.e15. [PMID: 29481977 DOI: 10.1016/j.jpain.2018.02.002] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/07/2017] [Revised: 01/29/2018] [Accepted: 02/12/2018] [Indexed: 01/21/2023]
Abstract
Pain after spinal cord injury (SCI-Pain) is one of the most debilitating sequelae of spinal cord injury, characterized as relentless, excruciating pain that is largely refractory to treatments. Although it is generally agreed that SCI-Pain results from maladaptive plasticity in the pain processing pathway that includes the spinothalamic tract and somatosensory thalamus, the specific mechanisms underlying the development and maintenance of such pain are yet unclear. However, accumulating evidence suggests that SCI-Pain may be causally related to abnormal thalamic disinhibition, leading to hyperactivity in the posterior thalamic nucleus (PO), a higher-order nucleus involved in somatosensory and pain processing. We previously described several presynaptic mechanisms by which activity in PO is regulated, including the regulation of GABAergic as well as glutamatergic release by presynaptic metabotropic gamma-aminobutyric acid (GABAB) receptors. Using acute slices from a mouse model of SCI-Pain, we tested whether such mechanisms are affected by SCI-Pain. We reveal 2 abnormal changes in presynaptic signaling in the SCI-Pain condition. The substantial tonic activation of presynaptic GABAB receptors on GABAergic projections to PO-characteristic of normal animals-was absent in mice with SCI-Pain. Also absent in mice with SCI-Pain was the normal presynaptic regulation of glutamatergic projections to the PO by GABAB receptors. The loss of these regulatory presynaptic mechanisms in SCI-Pain may be an element of maladaptive plasticity leading to PO hyperexcitability and behavioral pain, and may suggest targets for development of novel treatments. PERSPECTIVE This report presents synaptic mechanisms that may underlie the development and maintenance of SCI-Pain. Because of the difficulty in treating SCI-Pain, a better understanding of the underlying neurobiological mechanisms is critical, and may allow development of better treatment modalities.

Abstract
Decrease of thalamic blood flow contralateral to neuropathic pain has been described by several groups, but its relation with sensory deafferentation remains unclear. Here we report one instance where the thalamic effects of sensory deafferentation could be dissociated from those of neuropathic pain. A 50-year-old patient underwent a left medullary infarct leading to right-sided thermal and pain hypaesthesia up to the third right trigeminal division, as well as in the left face. During the following months the patient developed neuropathic pain limited to the left side of the face. Although the territory with sensory loss was much wider in the right (non painful) than in the left (painful) side of the body, PET-scan demonstrated significant reduction of blood flow in the right thalamus (contralateral to the small painful area) relative to its homologous region. After 3 months of right motor cortex stimulation the patient reported 60% relief of his left facial pain, and a new PET-scan showed correction of the thalamic asymmetry. We conclude that thalamic PET-scan hypoactivity contralateral to neuropathic pain does not merely reflect deafferentation, but appears related to the pain pathophysiology, and may be normalized in parallel with pain relief. The possible mechanisms linking thalamic hypoactivity and pain are discussed in relation with findings in epileptic patients, possible compensation phenomena and bursting thalamic discharges described in animals and humans. Restoration of thalamic activity in neuropathic pain might represent one important condition to obtain successful relief by analgesic procedures, including cortical neurostimulation.

Abstract
Breakthrough pain or transient worsening of pain in patients with an ongoing steady pain is a well known feature in cancer pain patients, but it is also seen in non-malignant pain conditions with involvement of nerves, muscles, bones or viscera. Continuous and intermittent pain seems to be a general feature of these different pain conditions, and this raises the possibility of one or several common mechanisms underlying breakthrough pain in malignant and non-malignant disorders. Although the mechanisms of spontaneous ongoing pain and intermittent flares of pain (BTP) may be difficult to separate, we suggest that peripheral and/or central sensitization (hyperexcitability) may play a major role in many causes of BTP. Mechanical stimuli (e.g. micro-fractures) changes in chemical environments and release of tumour growth factors may initiate sensitization both peripherally and centrally. It is suggested that sensitization could be the common denominator of BTP in malignant and non-malignant pain.

Abstract
Multiple sclerosis (MS) is an autoimmune inflammatory demyelinating disease of the central nervous system and a major cause of chronic neurological disability in young adults. Primary progressive MS (PPMS) constitutes about 10% of cases, and is characterized by a steady decline in function with no acute attacks. The rate of deterioration from disease onset is more rapid than relapsing remitting and secondary progressive MS types. Multiple system involvement at onset and rapid early progression have a worse prognosis. PPMS can cause significant disability and impact on quality of life. Recent studies are biased in favour of relapsing remitting patients as treatment is now available for them and they are more likely to be seen at MS clinics. Since prognosis for PPMS is worse than other types of MS, the focus of rehabilitation is on managing disability and enhancing participation, and application of a "neuropalliative" approach as the disease progresses. This chapter presents the symptomatic treatment and rehabilitation for persons with MS, including PPMS. A multidisciplinary approach optimizes the intermediate and long-term medical, psychological and social outcomes in this population. Restoration and maintenance of functional independence and societal reintegration, and issues relating to quality of life are addressed in rehabilitation processes.

Abstract
The aim of the present study is to assess the actual and lifetime frequency of neuropathic (trigeminal neuralgia, Lhermitte’s sign, dysesthesic pain) and somatic (painful muscle spasms and low back pain) pain and headache (tensive headache and migraine) in a cross-sectional sample of 428 consecutive multiple sclerosis (MS) outpatients followed-up in an Italian University MS center over a 3-month period. The impact of demographic and disease-related variables on pain and headache risk is also studied. A semi-structured questionnaire was administered during a face-to-face interview with MS patients and a multivariate logistic regression model is applied to obtain crude and adjusted risk measures. The mean age of the sample was 38.4 years, and female/male ratio was 1.65. The mean disease duration was 9.6 years and the median Expanded Disability Status Scale was 2.0, with most of the patients (74.8%) being affected by the relapsing–remitting form. Lifetime prevalence at the date of examination of at least one type of neuropathic or somatic pain was 39.8% in MS patients, with 58.5% also including headache, while the actual prevalence was 23.8% and 39.9%, respectively. After multivariate analysis, a progressive course of disease was shown to increase the risk of dysesthesic pain and painful muscle spasms, while greater disability was responsible for a higher risk of back pain. L’Hermitte’s sign was more frequent in younger patients, while females had a higher risk of headache. Pain and headache in MS are not negligible symptoms and a neurological examination should not miss the assessment of risk factors for specific types of pain for a more specific and individualized treatment.

UNLABELLED This cross-sectional study describes chronic pain in 94 persons with multiple sclerosis residing in the community. The characteristics of chronic pain, pain-related disability, pain treatments, barriers to health care, and impact on quality of life were examined. Sixty-four percent of participants reported chronic pain; of these, 60% had dysesthetic pain and 70% had episodic increases in pain. The mean numerical pain intensity rating score was moderate (5). Chronic Pain Grade was used to classify severity of pain, using scores for items for pain intensity and pain-related disability. Those in the higher pain grades had more disability and recorded more health care visits (P = .06) (not significant because of small sample size). Effective pain management techniques included analgesic medication and physical measures as reported by 54% and 44% participants, respectively. Participants' perceived barriers to health care included environmental and personal factors. Those with multiple sclerosis and pain, compared with those with no pain, showed a significant difference in the domain of psychological well-being scores (P = .01) on the Assessment of Quality of Life scale. Additionally, the domains of independent living (P = .009) and total scores (P = .04) showed better quality of life in participants with lower pain grades. Improved understanding of chronic pain in this population may facilitate early identification for timely intervention and minimize pain-related disability. PERSPECTIVE This article describes chronic pain in persons with multiple sclerosis living in the community. The information regarding pain prevalence, pain-related disability, and impact on quality of life provides insight into the complex multidimensional pain experience. Improved understanding of pain and early intervention may contribute to the overall well-being and decrease pain-related disability in this population.

Abstract
For the patient who has sustained traumatic brain injury (TBI), understanding the problem and listening to and believing the patient are prerequisites to treating pain. Because the information provided may be limited, communication skills problematic, and consistency variable, the challenge of treating individuals with TBI and pain can be daunting. Most painful conditions after TBI involve the musculoskeletal system; however, in conditions that are neurologically based, a careful and well-organized neurologic examination can be helpful to direct one's attention toward ordering the appropriate tests and treatments. The primary focus for helping patients with pain involves not only understanding the problem and assisting with symptom relief but also providing the opportunity to improve their functioning, physically and cognitively.

Abstract
This paper represents an expert-based consensus statement on pain assessment among older adults. It is intended to provide recommendations that will be useful for both researchers and clinicians. Contributors were identified based on literature prominence and with the aim of achieving a broad representation of disciplines. Recommendations are provided regarding the physical examination and the assessment of pain using self-report and observational methods (suitable for seniors with dementia). In addition, recommendations are provided regarding the assessment of the physical and emotional functioning of older adults experiencing pain. The literature underlying the consensus recommendations is reviewed. Multiple revisions led to final reviews of 2 complete drafts before consensus was reached.

Abstract
Central neuropathic pain is well known in multiple sclerosis (MS), but the underlying mechanisms are unclear. In the present study we studied sensory function in MS patients with pain, MS patients without pain and healthy subjects in order to clarify the role of sensory abnormalities in pain. Fifty MS patients with pain were randomly recruited from a previous epidemiological MS study in Aarhus County, Denmark. Age and gender stratified MS patients without pain (N=50) and healthy subjects (N=50) served as controls. Patients with pain underwent a structured pain interview. Sensory function was examined by bedside and quantitative sensory testing. Quality of life was assessed using the health-related quality of life questionnaire, SF-36. Patients with pain had lower pressure pain threshold than pain-free patients (260 kPa vs. 322 (median), P=0.02) otherwise quantitative sensory testing was similar. Pain patients more frequently had cold allodynia (9/50 vs. 0/50, P=0.003) and abnormal temporal summation (10/48 vs. 3/49, P=0.03). Fifty-eight percent had central pain. Central pain patients did not differ from musculoskeletal pain patients in quantitative sensory testing, but allodynia was more common in MS patients with central pain. Pain patients scored lower in all dimensions of SF-36 compared with pain-free patients and healthy subjects. The results suggest that pain in MS is central in more than half of the patients and is associated with mechanical or thermal hyperalgesia.

Abstract
The diagnosis and management of pain in the patient with traumatic brain injury (TBI) can be difficult in light of the limitations imposed by the cognitive, language, and behavioral deficits. With patients in the acute rehabilitation setting, one must be vigilant for the often subtle signs and symptoms of pain. Causes more commonly seen in the population with TBI as a consequence of the injury itself include dysautonomia, neuropathic pain, spasticity, and heterotopic ossification. Headaches may be a consequence of TBI or associated with it for other reasons. Sources of pain associated with TBI include deep venous thrombosis and others. The reader is reminded that patients with TBI are subject to all the causes of pain that affect the general population.
