RESUMO
CONTEXT: Patients with advanced cancer rarely complain of unexplained dizziness after excluding identifiable causes. Some patients become anxious because they attribute the dizziness to the progression of their cancer. We hypothesize that unexplained dizziness is associated with neck muscle hypertonicity, a noncancer-related secondary effect. However, most cases are associated with neck muscle hypertonicity, a noncancer-related secondary effect. AIMS: We evaluated the usefulness of hypnotic intervention that made patients aware of the relation between dizziness and neck muscle hypertonicity through the experience of muscle relaxation and recognition of muscle tension. SETTINGS AND DESIGN: Advanced cancer patients requiring palliative care with unexplained dizziness who received the intervention to induce neck muscle relaxation were retrospectively compared with patients who did not. SUBJECTS AND METHODS: The severity of dizziness that was evaluated using a numeric rating scale and the intervention efficacy rate were compared between the hypnotic and nonhypnotic groups as the primary endpoints, 7 days after the start of the intervention. Secondary endpoints included the effect size based on dizziness handicap inventory (DHI) scores before and after the intervention, and changes in patients' awareness of the cause of dizziness. RESULTS: The hypnotic intervention had a significantly greater efficacy rate (0.67, 95% confidence interval: 0.46-0.88) than the nonhypnotic intervention (0.26, 95% confidence interval: 0.08-0.44). DHI scores, especially on the emotional subscale, showed significant improvement after the intervention, and 71% of the patients were aware that neck muscle hypertonicity was the cause of dizziness. CONCLUSIONS: The rapid improvement in dizziness in the hypnotic group was considered to result from a change in patients' awareness of self-manageable neck muscle hypertonicity as the cause of dizziness.
RESUMO
Myofascial pain syndrome is started to be recognized as one of important factors of pain in cancer patients. However, no reports on features of myofascial trigger points were found in terminally-ill cancer populations. This time, we encountered 5 patients with myofascial pain syndrome and terminal cancer in whom delirium developed due to increased doses of opioid without a diagnosis of myofascial pain syndrome on initial presentation. The delirium subsided with dose reductions of opioid and treatment of myofascial pain syndrome. The common reason for a delayed diagnosis among the patients included an incomplete palpation of the painful sites, which led to unsuccessful myofascial trigger points identification. The features of myofascial trigger points included single onset in the cancer pain management site with opioid and the contralateral abdominal side muscles of the non-common sites. Withdrawal reflexes associated with cancer pain in the supine position, which are increasingly seen in the terminal cancer patients, were considered to have contributed to this siuation. We consider that careful palpation of the painful site is important, in order to obtain greater knowledge and understanding of the features of myofascial trigger points.
RESUMO
The aim of this study was to discuss the effect of autogenic training (AT) on patients with functional somatic syndrome (FSS) using salivary amylase, the skin temperature of the finger, subjective severity of symptoms, and psychological characteristics as measures. We assessed 20 patients with FSS and 23 healthy controls before and after AT. Baseline levels of salivary amylase prior to an AT session were significantly higher in the FSS group than in the control group. However, this difference was not significant after AT. The skin temperature of the finger increased after AT in both the FSS and control groups. AT contributed to the improvement of somatic symptoms in patients with FSS. Our results regarding psychological characteristics suggest that mood disturbances are deeply involved in the pathology of FSS. Individuals with FSS exhibited elevated levels of sympathetic activity compared with healthy controls. Our data indicates that AT eased dysregulation of the autonomic nervous system in patients with FSS. Thus, salivary amylase may be a useful index of change induced by AT in patients with FSS.

OBJECTIVES: Dyspnoea is a common and distressing symptom in patients with cancer. We aimed to analyse the association between dyspnoea and related factors and to estimate their causal relationship. METHODS: A cross-sectional study was conducted. Patients with cancer with dyspnoea and a mean Numerical Rating Scale (NRS) of ≥3 over 24 hours were enrolled at 10 institutions in Japan from December 2019 to February 2021. The outcomes included dyspnoea, cough and pain NRS over 24 hours, Eastern Cooperative Oncology Group Performance Status, Hospital Anxiety and Depression Scale, Somatosensory Amplification Scale, opioids for dyspnoea and respiratory failure. Path analyses were conducted to estimate the direct and indirect paths with reference to dyspnoea and related factors. RESULTS: A total of 209 patients were enrolled and 208 patients were included in the analysis. Cough worsened dyspnoea (ß=0.136), dyspnoea increased emotional distress (ß=1.104), emotional distress increased somatosensory amplification (ß=0.249) and somatosensory amplification worsened cough (ß=0.053) according to path analysis. CONCLUSION: There may be a vicious circle among dyspnoea and related factors: cough worsened dyspnoea, dyspnoea increased emotional distress, emotional distress increased somatosensory amplification and somatosensory amplification worsened cough. When treating dyspnoea in patients with cancer, managing these factors aimed at interrupting this vicious circle may be useful.

OBJECTIVES: Early palliative care reportedly contributes to the quality of life by improving coping skills in patients with cancer. The aims of the study are to (1) Build a self-coping system that makes it possible to perform a session of home-based heart rate variability biofeedback (HRV-BF) with resonant breathing in patients with sleep disturbance and to acquire its techniques early on, and (2) Examine its short-term efficacy and feasibility. METHODS: A randomised, open-label, comparative study was conducted in the presence or absence of home-based HRV-BF with resonant breathing using a portable HRV-BF device prior to bedtime. The participants were 50 patients with incurable cancer with sleep disturbance who underwent a hospital practice of HRV-BF with resonant breathing. The primary end point was the rate of change in sleep efficiency for 10-14 days. The Japanese version of the Pittsburgh Sleep Quality Index (subjective indicator) and actigraphy sleep parameters (objective indicators) were used for sleep assessments. RESULTS: The completion rate and implementation rate in the home-based HRV-BF group (n=25) were 96.0% and 91.4%, respectively. This group showed a significant improvement in sleep efficiency, sleep duration and the low-frequency component of HRV. Sleep latency worsened in this group, but a significant difference was not observed. CONCLUSIONS: A home practice of HRV-BF with resonant breathing made it possible to acquire its techniques early on and improve sleep and autonomic function; therefore, our study showed high short-term efficacy and feasibility required for a self-coping system.

Expectations for treatment have a favorable effect on the subsequent course of pain and behavior in patients. It is not known whether receiving hydrodissection while patients view their ultrasound image with doctors (visual feedback) is associated with positive treatment expectations. This was an exploratory, prospective, observational clinical trial. We explored the possibility that visual feedback immediately after ultrasound-guided hydrodissection increases the expectations for treatment, which could be one of the related factors for pain reduction. Treatment expectations were set as mediators of pain using path analysis. The primary endpoint was the numerical rating scale to assess expectations for treatment immediately after hydrodissection, between with and without the visual feedback. During 2019 and 2020, 136 outpatients received ultrasound-guided hydrodissection for myofascial pain syndrome. Of these, 65 (47.8%) patients received visual feedback during ultrasound-guided hydrodissection. Compared with the non-visual feedback group, the visual feedback group had higher expectations for treatment immediately after hydrodissection, and their expectations were maintained at day 14 of treatment (p < 0.001). A numerical rating scale (NRS) to assess expectations for treatment was similar before hydrodissection and immediately after hydrodissection was 8.4 (standard deviations, 1.6) in the visual feedback and 5.9 (standard deviations, 2.6) in the visual feedback. The proportion of increased expectations immediately after hydrodissection was 90.8% (95% CI: 83.7-97.9) in visual feedback group and 38.0% (95% CI: 26.7-49.3) in non-visual feedback group (p < 0.001). In the visual feedback group, 67.7% of patients showed improvement in pain numerical rating scale score by 50% or more at day 14, whereas such improvement was observed in only 36.6% of the non-visual feedback group (p < 0.001). Based on path analysis, the visual feedback had the greatest influence on pain numerical rating scale reduction at 14 days, indirectly due to increased expectations for treatment as a mediator (ß = 0.434). However, the adjusted R 2 values, which is the overall fit of the model, was low at 0.298. Visual feedback during ultrasound-guided hydrodissection increases the expectations for treatment immediately after hydrodissection, which could be one of the related factors for pain reduction in patients with myofascial pain syndrome.
RESUMO
Background: The term medically unexplained symptoms (MUS) is unhelpful for both patients and physicians, and more acceptable illness categories are needed as substitutes for MUS. While some potential substitutes are characterized by excessive psychological burden related to somatic symptoms, "functional somatic syndromes" (FSS) is a category that focuses on physical dysfunction and emphasizes similarities among individual syndromes. Examples of FSS include irritable bowel syndrome, functional dyspepsia, and fibromyalgia syndrome. This study aimed to distinguish FSS from MUS and compare the somatic and psychobehavioral characteristics of FSS with those of other diseases. Methods: This study included 1975 first-visit outpatients at a Japanese university hospital's general medicine clinic. According to their first-listed diagnosis, they were classified as having FSS, acute infection, organic disease (OD), psychiatric disorder, and unknown condition (UC). The somatic symptom burden and health-related quality of life (HRQoL) were assessed using the Somatic Symptom Scale-8 and EuroQol-5 Dimension, respectively; the involvement of psychobehavioral factors affecting somatic symptoms was also evaluated. Results: Overall, 33% of patients were included in the FSS category, and 93% of the supposed MUS (FSS and UC) were diagnosed with FSS. Compared with OD, FSS showed more severe somatic symptom burden, similar reduced HRQoL, and higher involvement of psychobehavioral factors. Conclusion: It can be useful to improve FSS diagnostic skills for the reduction of MUS misdiagnosis. Psychobehavioral factors might be less associated with MUS (in the narrow sense of the term) than FSS.
RESUMO
A trigger point injection (TPI) with local anesthetic in myofascial pain syndrome (MPS) often has the immediate effect of a decrease in pain. It is unknown whether the immediate effect of a decrease in pain affects the subsequent course of pain. It is also unknown whether expectations of a decrease in pain mediate such effects. We aimed to clarify how the effect of a decrease in pain immediately after TPI with local anesthetic affected the subsequent course of pain, and whether it increased expectations of a decrease in pain. This was a prospective, single-center, observational clinical trial. Patients with incurable cancer who visited the palliative care department and received TPI with local anesthetic for MPS were prospectively examined. We evaluated whether the immediate effect of a TPI with local anesthetic affects the subsequent course of pain in MPS by setting expectations as a mediator, using path analysis. From 2018 to 2020, 205 patients with incurable cancer received TPI for MPS. Of these, 58.1% of patients reported an immediate effect of decreased pain. Compared with the non-immediate effect group, the immediate effect group had higher expectations of a decrease in pain, and the higher expectation was maintained at 7 days (p < 0.001). The percentage of patients with pain reduction at 7 days after TPI was 88.2% in the immediate effect group and 39.5% in the non-immediate effect group (p < 0.001). The immediate effect of decreased pain had the greatest influence on pain reduction at 7 days, both directly (ß = 0.194) and indirectly through increased expectations (ß = 0.293), as revealed by path analysis. The effect of a decrease in pain immediately after TPI with local anesthetic affected the subsequent course of MPS pain in patients with incurable cancer by setting expectations as a mediator. There were limitations to the discussion of these findings because this was an observational study.
RESUMO
BACKGROUND: Many family caregivers of patients with cancer feel guilty about self-care. A meaningful relationship with patients reduces such negative feelings and functions as self-care for family caregivers. Moreover, handholding improves autonomic functions in non-cancer patients. However, the effects of handholding on both patients with cancer and family caregivers remain unknown. METHODS: We evaluated the effects of handholding on heart rate variability (HRV) in patients with cancer and their family caregivers. This randomized crossover study divided patients with cancer and their family caregivers into two trial groups: Handholding trial (the family caregiver holds the patient's hand for five minutes) and Beside trial (the family caregiver stays beside the patient without holding their hand). The study included 37 pairs of patients with cancer who received treatment in the cancer department of a university hospital in Japan and their family caregivers (n = 74). The primary end-point was the change in HRV before and during the intervention. RESULTS: The median performance status of the patients was 3. An interaction was observed between trials in the standard deviation of the normal-to-normal interval (SDNN) of HRV for family caregivers (F = 7.669; p = 0.006), and a significant difference in time course was observed between the trials (before p = 0.351; during p = 0.003). No interaction was observed between trials in the SDNN for patients (F = 0.331; p = 0.566). Only a main effect in time course (F = 6.254; p = 0.014) was observed. SDNN increased significantly during the intervention in both trials (Handholding trial: p = 0.002, Beside trial: p = 0.049). CONCLUSIONS: Handholding improves autonomic functions of family caregivers and may function as self-care for family caregivers. TRIAL REGISTRATION: UMIN000020557 . Registered on January 15, 2016.
RESUMO
BACKGROUND: Caregiving for people with cancer can cause chronic back pain (CBP) in family caregivers, but little is known about the associated caregiving-related factors. The study aim was to examine relationship between pain location and the factors related to care of cancer patients by family caregivers. METHODS: A cross-sectional survey was conducted among 320 family caregivers of advanced cancer patients from 2016 to 2018 at a single-unit university hospital. CBP locations were categorized as thoracic spine and lower back, and achievement of pain improvement goals defined as pain intensity (PI) ≤ personalized pain goal (PPG). Cancer caregiving-related factors were examined using a self-report questionnaire measuring subjective psychological stresses in family caregivers: depression, anxiety, insomnia, and caregiver burden. Medical records were used to determine patients' cancer severity based on performance status and time from survey until death. Multivariate logistic regression analysis was conducted. The dependent variable was presence of thoracic spine/low back pain; the independent variables were care recipient performance status and duration from survey until death, and caregiver scores on the Hospital Anxiety and Depression ScaleDepression, Hospital Anxiety and Depression Scale-Anxiety, Pittsburgh Sleep Quality Index-J, and Zarit Caregiver Burden Interview-J. RESULTS: In total, 31.4% of family caregivers had chronic thoracic spine pain and 28.3% chronic lower back pain. Of these, 60.0% of those with thoracic spine pain and 46.7% of those with lower back pain achieved their pain improvement goal. Logistic regression analysis showed that depression score was associated with chronic thoracic spine pain (both PI ≤ PPGs and PI > PPGs) (P=0.001 and P=0.027) and sleep score with chronic thoracic spine pain (PI > PPGs) (P=0.018). Performance status and time from survey until death were associated with chronic lower back pain (PI > PPGs) (P=0.034 and P=0.017). CONCLUSIONS: Our results suggest that the factors related to caregiving in cancer patients differ according to back pain location. To reduce CBP, it is important to address subjective psychological stress and physical burden with reference to back pain location.

Background: Despite the suggestion of a relationship between development or progression of myofascial pain syndrome (MPS) and psychological stress, few studies have reported its proportion or association with treatment efficacy. Objective: We aimed to investigate the proportion of MPS with psychological stress among cancer patients and to compare the efficacy of trigger point injection (TPI) in the same patients with/without psychological stress. Design: This was a prospective observational study. Setting/Patients: Participants were 205 patients with cancer who received TPIs for MPS at a hospital in Japan. Results: The proportion of patients with MPS and psychological stress was 0.57 (95% confidence interval [CI] 0.50-0.64). The TPI efficacy rate at seven days after treatment was 0.55 (95% CI 0.46-0.64) for patients with MPS and psychological stress and 0.82 (95% CI 0.74-0.90) for their counterparts without psychological stress (p < 0.004). The odds ratio for TPI efficacy seven days after treatment with psychological stress versus without psychological stress was 0.25 (95% CI 0.13-0.49). Conclusions: MPS was a clinical symptom of psychosomatic disorder in approximately half of our patients. The TPI efficacy for patients with MPS who had psychological stress was lower than for their counterparts without psychological stress. Trial registration: UMIN000041210.

BACKGROUND: Interoception refers to the body's physiological responses that occur in response to emotions. This phenomenon influences decision-making, an important cognitive ability that affects the maintenance of an exercise routine. However, it is controversial whether interoception is a reliable measure of an individual's traits or their response to emotion. Given this evidence, we hypothesized that performing an exercise with positive feelings could improve interoception and that the rational decision-making capabilities acquired by improved interoception would, in turn, help in maintaining an exercise routine. Persistent aerobic exercise is essential for improving cognitive and musculoskeletal function in the long term. Therefore, we aimed to investigate changes in interoception during moderate-intensity aerobic exercise at a level that might potentially improve cognitive function. METHODS: We devided 48 healthy university students into an exercise group (n = 37) and a control group (n = 11). The control group did not perform any exercises, while the exercise group performed bench step exercises at an intensity of 50% of heart rate reserve for 30 min a day, three times a week, for three months. We assessed their cognitive function by measuring their auditory information/working memory processing speed using a paced auditory serial addition task (PASAT) and evaluated their interoceptive accuracy (IA) using a heartbeat tracking task at baseline and 1, 2, and 3 months after the start of the exercise intervention. RESULTS: There was a significant positive correlation between IA and PASAT scores at baseline. However, exercise did not lead to a significant increase in PASAT scores of the exercise group as compared with the control group. IA scores increased at 2 and 3 months after the start of exercise only in the exercise group. CONCLUSIONS: This preliminary study showed an improvement in interoception after persistent moderate-intensity aerobic exercise. We believe that exercise-induced improvement of interoception may facilitate exercise maintenance through improved cognitive function. Statistical analysis did not explain the non-uniformity of sample sizes, therefore, future studies should have larger sample sizes with equal subjects in each group to allow for better comparability and generalizability.

RESUMO
OBJECTIVE: Patients with chronic musculoskeletal pain (CMP) have difficulty estimating their level of physical activity (PA). Factors associated with this difficulty have yet to be identified; however, identification could allow for increased accuracy in large-scale PA surveys, and enhanced self-management. The purpose of this study was to determine the relationship of interoception and alexithymia with differences between self-reported and objectively measured PA, and investigate factors as they relate to accurately self-reporting PA. METHODS: A cross-sectional survey of 33 patients with CMP and 32 healthy individuals was conducted from July 2018 to June 2019. We measured differences in Moderate to Vigorous Physical Activity (D-MVPA) using an accelerometer and self-report. A heartbeat tracking task (HTT) was used to measure interoception, and alexithymia was measured using the 20-item Toronto Alexithymia Scale (TAS-20). RESULTS: The CMP group (median 43.5 min/day, IQR 20.6-77.6) showed significantly higher D-MVPA values than the control group (median 22.5 min/day, IQR 6.7-34.9) (p < .001). In patients with CMP, D-MVPA positively correlated with TAS-20 (rho = 0.470, p = .006) and correlated negatively with HTT (rho = -0.390, p = .025). CONCLUSION: Inaccurate self-reported measurements of PA in patients with CMP are associated with alexithymia and interoception. This finding suggests that behavioral interventions targeting alexithymia and interoception in CMP patients could lead to improved self-monitoring.

Background: Alexithymia, or difficulty identifying and describing emotions and sensations, contributes to an increased risk of chronic pain, and low help-seeking. Objective: To investigate whether family caregivers of advanced cancer patients visiting a palliative care department had alexithymia, and whether this was related to their pain intensity, personalized pain goals, and help-seeking for chronic musculoskeletal pain. Design: A single-center cross-sectional survey. Measurements: Pain intensity was evaluated using a numerical rating scale. Pain improvement was evaluated against personal goals. Alexithymia was assessed using the Toronto Alexithymia Scale-20 (TAS-20), and anxiety and depression using the Hospital Anxiety and Depression Scale. Setting/Subjects: Of 320 family caregivers visiting the palliative care department, 152 (47.5%) had chronic musculoskeletal pain; all 152 were included in the study. Results: Alexithymia was observed in 36.2% of participants. Participants with higher scores on the TAS-20 tended to have higher pain intensity scores and personal pain goal scores. TAS-20 score had the strongest correlation with personal pain goals, with a correlation coefficient of 0.555 (p < 0.001). Conclusions: Pain intensity in family caregivers with alexithymia tended to be high. These participants set higher personal pain goals (lower goals for symptom improvement) than those without alexithymia. We found no difference in personal pain goal response between family caregivers with and without alexithymia. When we examine pain in family members with alexithymia who are caring for cancer patients, we need to recognize that they may set higher personal pain goals and seek less help.

Heart rate variability biofeedback (HRV-BF) is used as a skill in psychosomatic medicine, but is not yet established in the field of sleep. The present study aimed to evaluate the effect of HRV-BF with resonant frequency breathing (RFB) on sleep performed once every 2 weeks and the usefulness of practice of RFB using a portable device at home before bedtime. Participants were 69 family caregivers of patients with cancer that felt burdened by nursing care. We conducted a randomized controlled trial with an HRV-BF+Home practice group and an HRV-BF group. HRV-BF with RFB was administered to both groups at our medical institution for up to 30 min on the experiment days. Home practice involved RFB using a portable device, which was performed at home each day within 20 min before bedtime. Evaluation items were: change ratio of total score of the Pittsburgh Sleep Quality Index (PSQI) at 28 days after the trial started. In total, 52.2% of participants had insomnia. The two HRV-BF groups had decreased PSQI total scores, which indicated an improvement in PSQI total score near 5.5 on Day 28. The two HRV-BF groups had significantly increased HRV scores on Day 28, and there was correlation between the variation of PSQI total score and the variation of HRV score. The quality of sleep assessed by PSQI scores in the HRV-BF+Home practice group was significantly improved compared with the HRV-BF group on Day 28 (p = 0.001). This suggests HRV-BF may be a useful skill for enhancing sleep among family caregivers of patients with cancer, as well as supporting their autonomic nervous function. Additional actual regular practice of RFB (using a portable device at home before bedtime) may further enhance the effect.
RESUMO
Patients presenting with functional somatic syndrome (FSS) are common, and the symptoms are persistent and difficult to treat for doctors and costly for society. The aim of this study was to clarify the common pathophysiology of FSS, especially the relationship between hypothalamic-pituitary-adrenal (HPA) axis function and psychological characteristics of patients with FSS. The subjects were 45 patients with FSS and 29 healthy controls. Salivary free cortisol was measured in the morning, and psychological tests examining depression, anxiety and quality of life (QOL) were performed on the same day. In patients with FSS, depressive scores showed a significant negative correlation with salivary free cortisol in the morning, although in healthy controls, cortisol showed a significant positive correlation with depressive scores. In addition, the correlation between other psychological test scores and cortisol secretion in patients with FSS contrasted with that of controls. The relationship between cortisol and depression, anxiety or QOL, suggests that the HPA axis of patients with FSS is dysfunctional and does not function properly when patients with FSS are under stress. This dysfunction may explain the pathology of medically unexplained persistent symptoms of patients with FSS.

"Functional somatic syndromes" is one of the new terminologies in the medicine. However most of the primary-care physicians have already noticed the existence of the patient appeal their physical symptoms which is medically unexplained for a long time. On the other hand, the psychiatrists looked same physical symptoms as a symbolic representation of the patients' psychological conflicts, somatoform disorders. This new terminology "functional somatic syndromes" intends to integrate those two dimensions and to understand the patient as a whole person. In this special issue, we show the multi-dimensional aspects of "functional somatic syndromes" and intend to serve the clue to understand the patients with symptoms to all primary-care physicians in Japan.

The core pathological concept of functional somatic syndrome (FSS) is the discrepancy between patients' subjective experience of somatic symptoms and objective explanation by medical evaluation. Based on the discrepancy, the somatic symptoms with medically unexplained origins maintains, prolonged chronically, and grow up to FSS owing to various factors; physiological pathways, mood disturbance such as anxiety or depression, doctor-patient relationship, psychosocial stresses, alexithymia and alexisomia, and lack of support systems. As the pathology becomes more and more complicated, the psychosocial stresses, mood disturbance, and physiological dysfunction become more significant. Thus, the pathology falls into a vicious circle. Patients with FSS have common problems or characteristics, and have several overlapped diagnoses. FSS should be treated from aspects of both the similarity and the difference.

Functional somatic syndrome (FSS) with abdominal pain include functional gastrointestinal disorder, chronic pancreatitis, chronic pelvic pain syndrome, which generally contain autonomic dysfunction. Regarding the treatment of FSS, it is important to know about FSS for a therapist at first. Secondly, the therapist should find out physical dysfunction of patients positively, and confirm objectively the hypotheses about both peripheral and central pathophysiological mechanisms as much as possible. Heart rate variability is an easy method, and useful to assess autonomic function. After grasping the patient's explanatory model about the illness, the therapist showes the most acceptable treatment for the patient at last.

Background: There is currently no established therapy for allodynia, which is a type of neuropathic pain. However, high concentrations of topical anesthetics can anesthetize the skin and increase the sensory threshold to tactile stimulation. Objective: We aimed to evaluate the short-term effects and safety of 10% lidocaine ointment for treating allodynia in cancer pain. Design: This was a randomized double-blind crossover study comparing the efficacies of 10% lidocaine ointment and placebo ointment for the treatment of static allodynia and spontaneous pain within 24 hours after ointment application, using a numerical rating scale (NRS). Setting/Subjects: The subjects were 25 cancer patients with current pain rating of ≥4 on NRS of static allodynia in cancer pain. Results: The NRS scores for static allodynia were significantly lower in the lidocaine group than in the placebo group at two to eight hours after initial ointment application. A total of 56% of patients (95% confidence interval 35%-77%) had NRS improvements of ≥50% at eight hours after lidocaine ointment application compared with 20% (3%-37%) after placebo ointment application. There was no interaction between time and group in terms of NRS values for spontaneous pain (p = 0.835), but a significant main effect of group was found, with NRS scores being significantly lower in the lidocaine group than in the placebo group (p = 0.027). There were no adverse events associated with lidocaine use. Conclusions: Lidocaine ointment 10% can alleviate allodynia for two to eight hours after application.
