Abstract
PURPOSE Botulinum neurotoxin (BoNT) is a biological toxin produced by Clostridium botulinum. BoNT is a potent toxin extensively used in therapeutic interventions. This review provides an updated overview of the mechanisms of action and clinical applications of BoNT in head and facial region. STUDY SELECTION MEDLINE/PubMed searches were conducted using the terms "botulinum neurotoxin" and "dentistry" along with a combination of other related terms. In addition, studies were manually selected from reference lists of the selected articles. RESULTS The Food and Drug Administration in the United States initially approved BoNT to treat strabismus, blepharospasm, and hemifacial spasms. The use of BoNT in dermatology and cosmetics has been widely established and has created a revolution in these fields. Over the years, its applications in various medical specialties have expanded widely. Owing to its safety, efficacy, and long duration of action, it is well-accepted by patients. BoNT/A and BoNT/B are widely used in clinical practice. Several off-label uses of BoNT in the dental fraternity have yielded promising results. We have elaborated on the speculated mechanism of action, dosage, effective sites of injection, and adverse effects of each therapeutic application. The various clinical indications for BoNT include bruxism, myofascial pain, temporomandibular joint dislocation, hemifacial pain, orofacial dystonia, facial paralysis, chronic migraine, and trigeminal neuralgia. CONCLUSIONS BoNT is a safe treatment that can be used effectively, provided that the clinician has adequate knowledge regarding the mechanism, injection techniques, and local and systemic side effects and that it is administered cautiously and purposefully.

Abstract
The aim of this randomized study was to investigate whether stripping massage (SM) of myofascial trigger points in the lower rhomboid muscle could alleviate chest pain in patients following thoracoscopic surgery. In addition, a literature review was conducted to assess the effectiveness of various pain management techniques. Sixty adult patients who reported a visual analog scale (VAS) score of 4 or higher were randomly assigned to receive conventional analgesics alone (conventional group) or combined with SM twice daily for 2 weeks (SM group). VAS scores and the use of additional analgesics were evaluated on postoperative days 1, 3, 7, 14, and 30. Using the PubMed and Cochrane Library databases, a review of current pain management techniques was carried out up to January 31, 2022. A subgroup analysis was also performed to examine the treatment effect during different surgical periods and techniques. Results showed that the SM group had significantly lower VAS scores on postoperative days 3, 7, 14, and 30 (p < 0.001), as well as a shorter hospitalization duration and reduced need for additional analgesics (p < 0.001). The literature review included a total of 20 studies (2,342 cases of chest pain relief after thoracoscopic surgery), which indicated that serratus anterior plane (SAP) blocks were commonly used as a perioperative approach to reduce pain and opioid consumption. SM and SAP can both serve as adjuvant treatments for chest pain in patients following thoracoscopic surgery, with SM being a safe and noninvasive pain control option after hospital discharge.

Abstract
BACKGROUND Myofascial pain is a common, but poorly understood multifactorial condition. OBJECTIVE This study analyzed how the degree of central sensitization (nociplastic pain) can impact the response to physical therapy for patients with myofascial pain. METHODS This prospective, observational cohort study compared pain phenotyping and functional measures in 30 participants with non-acute neck/shoulder girdle primary myofascial pain following 3-months of physical therapy. The Fibromyalgia Survey Questionnaire Score served as a surrogate of central sensitization. RESULTS All participants demonstrated some benefit from physical therapy; however, those with moderate levels of nociplastic pain features were less likely to have clinically significant improvements on the Neck Disability Index, PEG score, or pain catastrophizing measures. Those with higher levels of nociplastic pain had a similar chance of showing improvement as those with lower levels, except regarding catastrophizing. Significant improvements were independent of the type or amount of therapy received. CONCLUSION The degree of nociplastic pain in patients with myofascial pain appears to be inversely related to improvements from a peripherally based treatment. This is not to say that individuals with moderate to higher levels of nociplastic pain do not benefit from physical therapy, but they proportionally benefit less.

Abstract
Background/Aims Myofascial pain syndrome is a frequent problem in the musculoskeletal system. As a method of treatment for myofascial pain syndrome, dry needling therapy is an effective and convenient treatment for patients because they do not need to be treated every day. However, as patients often have post-needle soreness or some patients are afraid of needles, there are limitations to this treatment. The purpose of this study is to compare the effectiveness of radial shockwave therapy with dry needling therapy to treat myofascial pain. Methods A total of 42 patients attending the rehabilitation department with at least one myofascial pain trigger point in their upper back muscles, were randomly assigned to receive radial shockwave therapy or dry needling therapy. Treatment was performed once a week for 3 weeks in both groups. Participants' pain pressure threshold, measured using an algometer, and pain levels, measured using a numeric pain scale, were assessed before the designated treatment was applied each week. Each patient also performed upper trapezius, rhomboid and infraspinatus muscle stretches twice a day throughout the study period. Results There was no difference in pain pressure threshold at the three trigger points before treatment with the different modalities commenced. At the end of the study, the radial shockwave therapy group had a significant improvement in trapezius pain pressure threshold, increasing from 11.7 at baseline to 14.8 at the end of study. There was no significant between-group difference in pain level (P=3.4 vs P=2.6) at the end of the study. Both treatments significantly reduced pain levels: from 7.2 to 3.4 in the radial shockwave group (P<0.001) and from 6.8 to 2.6 in the dry needling therapy group (P<0.001). Conclusions Dry needling and radial shock wave therapies are effective in reducing myofascial pain syndrome originating in the upper back muscles. Participants' pain pressure threshold increased after 3 weeks of treatment with both therapies. Radial shock therapy can be used as an alternative to dry needling in the treatment of myofascial pain syndrome in patients who have trouble attending daily physical therapy or in whom dry needling therapy is contraindicated.

Abstract
BACKGROUND Acupuncture has been used to treat myofascial pain syndrome (MPS) for 2000 years in China, but its mechanisms are still not entirely clear. In the present study, we explored the effects of transcutaneous electrical acupuncture point stimulation (TEAS) at an Ashi acupuncture point on expression of phosphorylated c-Jun N-terminal kinase (p-JNK) in the dorsal root ganglion (DRG) using a rat model of MPS. METHODS 32 rats were divided into four groups: normal, MPS, MPS+TEAS and MPS+sham- TEAS. MPS was produced by a blunt strike to the left vastus medialis combined with eccentric exercise for 8 weeks. Rats in the MPS+TEAS group received TEAS (6-9 mA, 2 Hz, 30 min) treatment at the Ashi acupuncture point for 2 weeks; rats in the MPS+sham -TEAS group had the same electrodes applied but received no stimulation. Paw withdrawal thermal latency (PWTL) was studied at baseline and on days 3, 7, 11 and 15 after treatment. Haematoxylin and eosin staining was used to examine for morphological changes in the left vastus medialis muscles; expression of p-JNK in the L3-L5 DRG was determined by immunofluorescence staining and western blotting after treatment. RESULTS Compared with the normal group, PWTL decreased significantly (P<0.01) and the expression of p-JNK in the DRG increased in the MPS and MPS-sham-TEAS groups (P<0.01); compared with the MPS group, PWTL was increased significantly (P<0.01) and expression of p-JNK in the DRG was decreased in the MPS+TEAS group. However, when compared with the normal group, PWTL did not recover to baseline and expression of p-JNK was still higher. CONCLUSION TEAS treatment may produce an analgesic effect, probably by inhibiting the expression of p-JNK in the DRG of rats with MPS.

Abstract
BACKGROUND Motor neuron diseases (MND) represent a group of disorders that evolve with inexorable muscle weakness and medical management is based on symptom control. However, deeper characterization of non-motor symptoms in these patients have been rarely reported. METHODS This cross-sectional study aimed to describe non-motor symptoms in MND and their impact on quality of life and functional status, with a focus on pain and sensory changes. Eighty patients (31 females, 55.7 ± 12.9 years old) with MND underwent a neurological examination, pain, mood, catastrophizing and psychophysics assessments [quantitative sensory testing (QST) and conditioned pain modulation (CPM)], and were compared to sex- and age-matched healthy controls (HC). RESULTS Chronic pain was present in 46% of patients (VAS =5.18 ± 2.0). Pain of musculoskeletal origin occurred in 40.5% and was mainly located in the head/neck (51%) and lower back (35%). Neuropathic pain was not present in this sample. Compared to HC, MND patients had a lower cold detection threshold (p < 0.002), and significantly lower CPM scores (4.9 ± 0.2% vs. 22.1 ± 0.2%, p = 0.012). QST/CPM results did not differ between MND patients with and without pain. Pain intensity was statistically correlated with anxiety, depression and catastrophism, and spasticity scores were inversely correlated with CPM (ρ = -0.30, p = 0.026). CONCLUSIONS Pain is frequently reported by patients with MNDs. Somatosensory and CPM changes exist in MNDs and may be related to the neurodegenerative nature of the disease. Further studies should investigate the most appropriate treatment strategies for these patients. SIGNIFICANCE We report a comprehensive evaluation of pain and sensory abnormalities in motor neuron disease (MND) patients. We assessed the different pain syndromes present in MND with validated tools, and described the QST and conditioned pain modulation profiles in a controlled design.

Abstract
Background The aim of this study was to evaluate sympathetic nervous system (SNS) activity following dry needling (DN) treatment, by using the sympathetic skin response (SSR) method in female patients diagnosed with myofascial pain syndrome (MPS). Methods Twenty-nine MPS patients with trapezius muscle pain and 31 healthy subjects were included in this study. During a single treatment session, DN treatment was applied into trigger points, for a duration of 10 minutes. Healthy patients were subjected to SSR in weeks 1 and 4; whereas the patient group was subjected to SSR 1 week prior to their treatment and in the first, second, third and fourth weeks following the completion of their treatment. Results We found diminished latency on both sides. A significantly high algometer measurement (P < 0.05) was observed in the control group. DN treatment was effective in diminishing the visual analog scale (VAS) (P < 0.001), pressure pain threshold (PPT) (P < 0.01), and SSR (P < 0.001). No SSR change was detected in the healthy group after the follow-up period (P > 0.05). Conclusion DN is an effective treatment in MPS and trigger point (TP). This original study is the first to deal with the SSR in MPS and weekly SSR trailing, requiring further investigation to solidy findings.

Abstract
Piriformis syndrome is an underdiagnosed extraspinal association of sciatica. Patients usually complain of deep seated gluteal pain. In severe cases the clinical features of piriformis syndrome are primarily due to spasm of the piriformis muscle and irritation of the underlying sciatic nerve but this mysterious clinical scenario is also described in lumbar spinal canal stenosis, leg length discrepancy, piriformis myofascial pain syndrome, following vaginal delivery, and anomalous piriformis muscle or sciatic nerve. In this paper, we describe piriformis and fibromyalgia syndrome in a 30-year-old young lady, an often missed diagnosis. We also focus on management of the piriformis syndrome.

Abstract
BACKGROUND This is an updated version of the original Cochrane review published in Issue 4, 2012. Myofascial pain syndrome (MPS) is a regional muscular pain syndrome characterised by the presence of trigger points, which are painful points in one or more muscles. The pain can be felt at the site where the trigger point is located or it can be felt away from that place when the muscle is pressed (referred pain). Botulinum toxin is a protein produced by the bacterium Clostridium botulinum and is a potent neurotoxin that eventually inhibits muscle contractions. It is capable of selectively weakening painful muscles and interrupting the pain cycle. OBJECTIVES To assess the effectiveness and safety of botulinum toxin A (BTXA) in the treatment of myofascial pain syndrome (MPS), excluding MPS in neck and head muscles. SEARCH METHODS This is an updated version of the original Cochrane review published in Issue 4, 2012. The search strategy for the update was the same as in the original review and we searched CENTRAL in The Cochrane Library (2013, Issue 11 of 12), MEDLINE (Ovid) (2012 to 29 November 2013) and EMBASE (Ovid) (2012 to 27 November 2013). The search strategy was composed of terms for myofascial pain and botulinum toxin. For the original review, we also searched the Cochrane Pain, Palliative and Supportive Care (PaPaS) Review Group Specialised Register until December 2011, PubMed (from 1966 to 2011) and LILACS (from 1982 to 2011). There was no language restriction. SELECTION CRITERIA We included randomised controlled trials (RCTs) involving botulinum toxin for treating participants with MPS. We excluded studies with MPS of the neck and head from this review as they have already been assessed in existing systematic reviews. We considered a diagnosis of MPS to be based on the identification of trigger points in the taut band through palpation of sensitive nodules, local twitch response and specific patterns of referred pain associated with each trigger point. DATA COLLECTION AND ANALYSIS Two review authors independently screened identified studies, extracted data, assessed trial quality and analysed results using the Cochrane PaPaS Review Group criteria. MAIN RESULTS Four studies with a total of 233 participants, comparing BTXA with placebo, met the inclusion criteria. In one study with 145 participants, significant improvement rates of pain intensity scores and duration of daily pain were demonstrated when comparing BTXA with placebo. The three other studies showed that there was no statistically significant difference between BTXA and placebo in pain intensity. AUTHORS' CONCLUSIONS Since the first publication of this review, no new studies were found. There is inconclusive evidence to support the use of botulinum toxin in the treatment of MPS based on data from four studies with a total of 233 participants, which we considered were of sufficient quality to be included in this review. Meta-analyses were not possible due to the heterogeneity between studies. We suggest that in future studies the same methodology to assess pain, a standardised dose of treatment, follow-up of at least four months (to observe the maximum and minimum curve of the drug effect) and appropriate data presentation should be used. More high-quality RCTs of botulinum toxin for treating MPS need to be conducted before firm conclusions on its effectiveness and safety can be drawn.

Abstract
SUMMARY The objective of this article was to perform a narrative review regarding the treatment of myofascial pain syndrome and to provide clinicians with treatment recommendations. This paper reviews the efficacy of various myofascial pain syndrome treatment modalities, including pharmacological therapy, injection-based therapies and physical therapy interventions. Outcomes evaluated included pain (visual analog scale), pain pressure threshold and range of motion. The evidence found significant benefit with multiple treatments, including diclofenac patch, thiocolchicoside and lidocaine patches. Trigger point injections, ischemic compression therapy, transcutaneous electrical nerve stimulation, spray and stretch, and myofascial release were also efficacious. The authors recommend focusing on treating underlying pathologies, including spinal conditions, postural abnormalities and underlying behavioral issues. To achieve maximum pain reduction and improve function, we recommend physicians approach myofascial pain syndrome with a multimodal plan, which includes a combination of pharmacologic therapies, various physical therapeutic modalities and injection therapies.

Abstract
Myofascial pain syndrome (MPS) is a regional pain disorder caused by taut bands of muscle fibers in skeletal muscles called myofascial trigger points. MPS is a common disorder, often diagnosed and treated by physiatrists. Treatment strategies for MPS include exercises, patient education, and trigger point injection. Pharmacologic interventions are also common, and a variety of analgesics, antiinflammatories, antidepressants, and other medications are used in clinical practice. This review explores the various treatment options for MPS, including those therapies that target myofascial trigger points and common secondary symptoms.

Distinctive clinical features in arthro-myalgic patients with and without aluminum hydroxyde-induced macrophagic myofasciitis: an exploratory study. J Inorg Biochem 2013; 128:262-6. [PMID: 23921285 DOI: 10.1016/j.jinorgbio.2013.07.020] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/23/2013] [Revised: 07/11/2013] [Accepted: 07/13/2013] [Indexed: 11/25/2022]
Abstract
UNLABELLED Macrophagic myofasciitis (MMF) is a specific histological lesion assessing the persistence of vaccine-derived aluminum oxyhydroxide in muscle tissue, at a site of previous immunization. Long-lasting MMF is usually detected in patients with arthromyalgias, chronic fatigue, and stereotyped cognitive dysfunction. MMF diagnosis requires muscle biopsy, an invasive procedure not suitable for the routine investigation of all patients with musculoskeletal pain. To help decision making in routine practice, we designed a retrospective analysis of 130 consecutive arthro-myalgic patients, previously immunized with aluminum-containing vaccines, in whom deltoid muscle biopsy was performed for diagnostic purposes. According to biopsy results, the patients were ascribed to either the MMF or the non-MMF group. MMF was diagnosed in 32.3% of the patients. MMF and non-MMF groups were similar according to both the injected vaccines and the delay between vaccination and biopsy. MMF patients had less frequent fibromyalgia than non-MMF patients (≥11 fibromyalgic tender points in 16.6 vs 55.5%, p < 0.04), and more often abnormal evoked potentials suggestive of CNS demyelination (38.5 vs 5.7%, p < 0.01). Predictive bioclinical scores based on simple variables such as the number of fibromyalgic tender points, arthralgias, and spinal pain, had sensitivity ranging from 50 to 88.1% and specificity from 36.4 to 76.1%. IN CONCLUSION (i) most aluminum-containing vaccine receivers do not have long-lasting MMF in their muscle, but the prevalence of MMF among patients with arthromyalgia following immunization is substantial; (ii) patients with MMF have more CNS dysfunction and less fibromyalgic tender points than non-MMF patients; (iii) predictive scores may help to identify patients at high vs low risk of MMF.

Abstract
Myofascial pain syndrome (MPS) is a musculoskeletal condition characterized by regional pain and muscle tenderness associated with the presence of myofascial trigger points (MTrPs). The last decade has seen an exponential increase in the use of botulinum toxin (BTX) to treat MPS. To understand the medical evidence substantiating the role of therapeutic BTX injections and to provide useful information for the medical practitioner, we applied the principles of evidence-based medicine to the treatment for cervico-thoracic MPS. A search was conducted through MEDLINE (PubMed, OVID, MDConsult), EMBASE, SCOPUS and the Cochrane database for the period 1966 to 2012 using the following keywords: myofascial pain, muscle pain, botulinum toxin, trigger points, and injections. A total of 7 trials satisfied our inclusion criteria and were evaluated in this review. Although the majority of studies found negative results, our analysis identified Gobel et al.'s as the highest quality study among these prospectively randomized investigations. This was due to appropriate identification of diagnostic criteria, excellent study design and objective endpoints. The 6 other identified studies had significant failings due to deficiencies in 1 or more major criteria. We conclude that higher quality, rigorously standardized studies are needed to more appropriately investigate this promising treatment modality.

Abstract
Follicular lymphoid hyperplasia of the palate is a benign lymphoproliferative lesion of unknown pathogenesis. It presents usually in female patients as a painless, firm, well-demarcated, usually nonulcerated, slow-growing lesion on the palate that histopathologically may resemble a lymphoma. The authors describe a patient with this condition that was successfully treated with intralesional steroid injections. Previously reported cases were reviewed to assess the results of various treatment modalities and disease-free outcome. A nonsurgical approach to the management of follicular lymphoid hyperplasia may have better patient acceptance and satisfaction without recurrence.

Abstract
Myofascial pain syndrome (MPS) is defined as pain that originates from myofascial trigger points in skeletal muscle. It is prevalent in regional musculoskeletal pain syndromes, either alone or in combination with other pain generators. The appropriate evaluation and management of myofascial pain is an important part of musculoskeletal rehabilitation, and regional axial and limb pain syndromes. This article reviews the current hypotheses regarding the treatment modalities for myofascial trigger points and muscle pain. Through a critical evidence-based review of the pharmacologic and nonpharmacologic treatments, the authors aim to provide clinicians with a more comprehensive knowledge of the interventions for myofascial pain.

Abstract
BACKGROUND Myofascial pain syndrome (MPS) is a regional muscular pain syndrome characterised by the presence of trigger points, which are painful points in one or more muscles. The pain can be felt at the site where the trigger point is located or it can be felt away from that place when the muscle is pressed (referred pain). Botulinum toxin is a protein produced by the bacterium Clostridium botulinum and is a potent neurotoxin that eventually inhibits muscle contractions. It is capable of selectively weakening painful muscles and interrupting the pain cycle. OBJECTIVES To assess the effectiveness and safety of botulinum toxin in treating MPS, excluding MPS in neck and head muscles. SEARCH METHODS The search strategy was composed of terms for myofascial pain and botulinum toxin. We searched the Cochrane Pain, Palliative and Supportive Care (PaPaS) Review Group's Specialised Register until December 2011, CENTRAL (Cochrane Database of Systematic Reviews 2011, Issue 4), PUBMED (from 1966 to 2011), EMBASE (from 1980 to 2011) and LILACS (from 1982 to 2011). There was no language restriction. SELECTION CRITERIA We included randomised controlled trials (RCTs) involving botulinum toxin for treating participants with MPS. We excluded studies with MPS of the neck and head from this review, as they have already been assessed in existing systematic reviews. We considered a diagnosis of MPS to be based on the identification of trigger points in the taut band through palpation of sensitive nodules, local twitch response and specific patterns of referred pain associated with each trigger point. DATA COLLECTION AND ANALYSIS Two review authors independently screened identified studies, extracted data, assessed trial quality and analysed results using the Cochrane PaPaS Review Group criteria. MAIN RESULTS Four studies with a total of 233 participants, comparing botulinum toxin A (BTXA) with placebo, met the inclusion criteria. In one study with 145 participants, a significant improvement rate of pain intensity scores, as shown by the mean difference (MD) of -0.23 (95% confidence interval (CI) -0.26 to -0.20; P value < 0.00001) and duration of daily pain (MD -1.11; 95% CI -1.37 to -0.85; P value < 0.00001), was demonstrated when comparing BTXA with placebo. The three other studies showed that there was no statistically significant difference between BTXA and placebo in pain intensity. AUTHORS' CONCLUSIONS There is inconclusive evidence to support the use of botulinum toxin in the treatment of MPS based on data from four studies with a total of 233 participants, which we considered adequate to be included in this review. Meta-analyses were not possible due to the heterogeneity between studies. We suggest that in future studies the same methodology to assess pain, a standardised dose of treatment, follow-up of at least four months (to observe the maximum/minimum curve of the drug effect) and appropriate data presentation should be used. More high-quality RCTs of botulinum toxin for treating MPS need to be conducted before firm conclusions on its effectiveness and safety can be drawn.

Abstract
This article provides a comprehensive review of rheumatologic considerations for a clinician when evaluating a patient with neck pain. Clearly, anatomic derangements of the cervical spine should be considered when a patient complains of cervicalgia. However, one must also entertain the possibility of a systemic illness as the cause of the pain. Examples of diseases that may present with a prominent feature of neck pain are discussed, including rheumatoid arthritis, ankylosing spondylitis, diffuse idiopathic skeletal hyperostosis, myositis, and fibromyalgia. Evidence of an underlying rheumatic illness may guide the clinician in a different therapeutic direction.

Abstract
OBJECTIVE To assess the efficacy of 2 invasive techniques for treating myofascial pain: trigger point acupuncture and 1% lidocaine infiltration of trigger points. MATERIAL AND METHODS Patients who met the inclusion criteria were randomized to 2 groups for evaluation at our pain clinic over a period of 7 months. Each patient had 4 treatment sessions. Response was evaluated on a visual analog scale (VAS) and by means of the Lattinen test. RESULTS Twenty-one patients were enrolled. Eleven underwent acupuncture and 10 received lidocaine infiltrations. When post-treatment pain was assessed, the mean (SD) VAS scores fell from 5.50 (2.08) to 2.45 (2.05) in the acupuncture group and from 4.8 (2.03) to 2.2 (1.91) in the lidocaine group. Lattinen test scores also fell, from 10.63 (2.69) to 8.54 (3.14) in the acupuncture group and from 10.9 (1.59) to 8.60 (2.63) in the lidocaine group. There were no statistically significant differences between the 2 treatment groups. CONCLUSION Both acupuncture and lidocaine infiltration of trigger points were effective in reducing pain intensity after treatment and in improving quality of life. One method could not be shown to be better than the other for treating myofascial pain.

Abstract
Regional soft-tissue complaints are commonplace, and they usually relate to a disease process, such as strain, inflammation or degeneration of a muscle, tendon or related muscle-tendon unit. The clinical features and investigations of the causative processes of these complaints are characteristic, and outcomes to treatments are usually predictable and satisfactory. Regional pain syndromes are different: these syndromes present with regional pain and tenderness, and other sensory symptoms unaccounted for by a simple musculoskeletal mechanistic explanation. Approved classification criteria for regional pain syndromes are lacking, and these syndromes are poorly understood and frequently misdiagnosed. Regional pain syndromes often occur after injury and overlap extensively with other musculoskeletal pain syndromes, in terms of clinical signs and symptoms. The clinician and patient are often confused about the nature of the problem and routine treatments directed to putative tissue damage will fail. Review of the epidemiology of regional pain syndromes combined with knowledge of other similar pain syndromes has enabled an evolving understanding of the condition. The musculoskeletal and central nervous systems both contribute to regional pain syndromes, through spine-related pain mechanisms and central sensitization, respectively. The patient's emotional state, particularly the effect on pain modulation, links these two systems.

Abstract
Chronic pain plagues older adults more than any other age group; thus, practitioners must be able to approach this problem with confidence and skill. This article reviews the assessment and treatment of the most common chronic nonmalignant pain conditions that affect older adults--myofascial pain, generalized osteoarthritis, chronic low back pain (CLBP), fibromyalgia syndrome, and peripheral neuropathy. Specific topics include essential components of the physical examination; how and when to use basic and advanced imaging in older adults with CLBP; a stepped care approach to treating older adults with generalized osteoarthritis and CLBP, including noninvasive and invasive management techniques; how to diagnose and treat myofascial pain; strategies to identify the older adult with fibromyalgia syndrome and avoid unnecessary "diagnostic" testing; pharmacological treatment for the older adult with peripheral neuropathy; identification and treatment of other factors such as dementia and depression that may significantly influence response to pain treatment; and when to refer the patient to a pain specialist. While common, chronic pain is not a normal part of aging, and it should be treated with an emphasis on improved physical function and quality of life.
