Workplace physiotherapy for musculoskeletal pain-relief in office workers: A pilot study.

BACKGROUND:Musculoskeletal pain is highly prevalent among office workers and causes high costs to the public health system. Strategies including education and exercise are recommended, with major benefits when conducted by physical therapists in the occupational environment. However, the required investment is uncommon among companies. This study aimed to evaluate the efficacy of a multimodal physiotherapy intervention to relieve musculoskeletal pain in office workers.MATERIALS AND METHODS:The study employed a single group study with a pre-post study design and was conducted at Universidad San Jorge in 2018. Outcome variables were: workplace ergonomics (INSHT Guide), existence and severity of musculoskeletal disorders (Nordic Musculoskeletal Questionnaire), musculoskeletal pain intensity (Numeric Rating Scale), and Clinical Global Impression Scale. Office workers in a university setting (n = 24, 19 females) were assessed at baseline, after 4 weeks of in-person sessions and following 3 weeks of autonomous performance. The physiotherapy program included education, ergonomic supervision, self-treatment, strengthening, and stretching exercises. A repeated-measures ANOVA or Friedman test (with post hoc comparisons) and Chi-squared test were used to compare the study variables.RESULTS:At baseline, cervical spine (54%), shoulder (42%), and lumbar regions (37.5%) were the most symptomatic regions according to the Nordic Musculoskeletal Questionnaire. Even if the proportion of symptomatic areas did not decrease significantly after the intervention, a great reduction of musculoskeletal pain intensity was observed after the program in the cervical (P < 0.001), lower back (P = 0.005), shoulder (P = 0.006) regions, and in the overall pain level (P < 0.001).CONCLUSIONS:These results support that a multimodal physiotherapy program can relieve work-related musculoskeletal pain in office workers and serve as a basis for future controlled trials.

QOLP-16. EFFICACY OF SCRAMBLER THERAPY (CALMARE®) FOR THE TREATMENT OF CHRONIC CHEMOTHERAPY-INDUCED PERIPHERAL NEUROPATHY

Abstract BACKGROUND Chemotherapy-induced peripheral neuropathy (CIPN) is a common and serious consequence of cancer treatment that, for up to 30% of patients, persists beyond six months of completing chemotherapy. Scrambler therapy (ST) is a therapeutic modality with emerging evidence supporting its ability to diminish CIPN symptoms. METHODS Data was from a convenience sample of 24 CIPN patients (with symptoms between 1-240 months after platinum-based, taxane, or combination chemotherapy) completing 10 sessions of ST using the Calmare® device in the City of Hope Outpatient Physical Therapy Department. Patients were treated for ~45 minutes per session over 10 sessions. Patients received a standardized assessment pre- and post ST that included: EORTC chemotherapy-induced peripheral neuropathy questionnaire (QLQ-CIPN20), mono-filament testing, pain intensity numerical rating scale, numbness scale, extensor hallicus longus strength, Timed Up and Go, Romberg, and single leg balance. RESULTS Regardless of length of symptoms, significant changes were seen in post-treatment assessment of quality of life as measured by the QLQ-CIPN-20 and numbness scale. Post-treatment QLQ-CIPN-20 total scores decreased by an average of 7.1 points (n= 24, p&amp;lt; .01). Numbness in the left lower extremity decreased by an average of 1 point of the 0-4 point scale (n=24, p=.0007) and 1.09 points on the right lower extremity (n=24, p &amp;lt; .0004). There was a trend towards improvements in pain, monofilament testing, single leg balance, and Romberg test, though they did not reach a level of significance. Surprisingly, only 3 of 24 patients reported pain related to their CIPN at the start of treatment. CONCLUSION For patients with CIPN, scrambler therapy improves numbness and improves quality of life measures. This suggests an important role for this treatment modality in cancer patients suffering from this debilitating condition.

Gait Function in Adults Aged 50 Years and Older With Spina Bifida

ObjectiveTo study gait function among individuals with spina bifida (SB) aged 50 years or older. DesignA cross-sectional study conducted in 2017. SettingHome-dwelling participants from all regions in Norway. ParticipantsIndividuals between the ages of 51 and 76 years (N=26; 16 women) categorized as independent walkers (n=9), walkers with aids (n=10) and nonwalkers (n=7). InterventionsNot applicable. Main Outcome MeasuresQuestionnaire, pain assessment, anthropometry, Falls Efficacy Scale International (FES-I), objective gait analysis, 6-minute walk test (6MWT), and timed Up and Go (TUG). ResultsWalking speed correlated with SB severity (ρ=–.59; P=.008). Individuals who walked slower than 0.81 m/s had a higher body mass index (BMI) than those who walked faster (P=.008). Independent walkers walked slower than healthy age-matched walkers (P=.046); spatiotemporal variables showed that this was owing to shorter steps rather than cadence. The mean TUG was 10.6±2.6 seconds in independent walkers and 20.2±6.5 in walkers with aids (P<.01). The mean 6MWT was 504±126 meters in independent walkers and 316±88 in walkers with aids (P<.01). The mean pain intensity (numeric rating scale) was 4.9±2.2 in independent walkers and 4.2±1.6 in walkers with aids, but the difference was not statistically significant. FES-I was significantly lower among independent walkers (mean, 23.6±3.9) than walkers with aids (mean, 31.4±10.0) (P=.042). ConclusionsParticipants commonly experienced an early onset deterioration in gait function, and walking speed was influenced by SB severity and BMI. This highlights the importance of early monitoring and weight management during follow-up for SB.

Effect of Protocol-based Pain Management on Patient Reported Pain During Radiation for Head and Neck Cancer

Disease- or treatment-related pain is a common and often debilitating symptom among head and neck cancer (HNC) patients. Inadequate pain control is associated with psychological distress, reduced social activities, decreased social support, and increased frequency of treatment interruptions which has been linked to worse outcomes. The purpose of this analysis was to determine the effect of protocol treatment on patient-reported pain in HNC patients undergoing radiation. The nurse-assessed pain intensity numeric rating scale (PI-NRS) scores were reviewed for patients with HNC enrolled in a prospective trial of microsphere oxycodone for extended release analgesia during RT (NCT03317730). Analgesia was prescribed in accordance with the World Health Organization pain ladder with the only restriction being that the extended release opioid analgesic was microsphere oxycodone. A comparison cohort was constructed by matching participants in the protocol cohort 5-to-1 at the individual patient level based on stage, tumor location, gender, and pain at presentation. Patients in the usual care cohort were prescribed analgesia at the discretion of the treating physician. In both cohorts, pain was assessed once weekly during RT and at 1 and 3 months after completion of RT. PI-NRS scores were characterized as mild (0-3), moderate (4-6), or severe (7-10). Between group differences of frequencies were assessed using the χ2 test and means were assessed using the independent samples T-test or non-parametric independent samples testing, where appropriate. The 26 eligible patients enrolled in the clinical trial comprised the protocol cohort and 130 patients were in the usual care cohort. No statistically significant differences were observed with respect to baseline patient and treatment characteristics. The PI-NRS at time of consultation for patients in the protocol cohort was 2.0 (SD ±2.5) and was 2.5 (SD ±3.0) in the usual care cohort (p = 0.74). Patients treated in the protocol cohort rated their pain as moderate or severe in 32.0% of encounters as compared to 46.1% of encounters within the usual care cohort (p = 0.043). Patients treated in the protocol cohort rated their pain as severe in 15.6% of encounters as compared to 17.9% of encounters within the usual care cohort (p = 0.65). In this study, patients with HNC who participated in a supportive care clinical trial of microsphere oxycodone for pain management during radiation were less likely to report moderate-to-severe pain than patients treated with usual care. No differences in the frequency of severe pain was noted. Ongoing research is critically needed to determine the optimal pain management strategy for patients with HNC.

The effect of an integrated multidisciplinary rehabilitation programme for patients with chronic low back pain: Long-term follow up of a randomised controlled trial

Objective: To compare the long-term effectiveness of an integrated rehabilitation programme with an existing rehabilitation programme, in terms of back-specific disability, in patients with chronic low back pain. Design: A single-centre, pragmatic, two-arm parallel, randomised controlled trial. Setting: A rheumatology rehabilitation centre in Denmark. Subjects: A total of 165 adults (aged ⩾ 18 years) with chronic low back pain. Interventions: An integrated programme (a pre-admission day, two weeks at home, two weeks inpatient followed by home-based activities, plus two 2-day inpatient booster sessions, and six-month follow-up visit) was compared with an existing programme (four-week inpatient, and six-month follow-up visit). Main measure: The primary outcome was disability measured using the Oswestry Disability Index after one year. Secondary outcomes included pain intensity (Numerical Rating Scale), pain self-efficacy (Pain Self-Efficacy Questionnaire), health-related quality of life (EuroQol-5 Domain 5-level (EQ-5D)), and depression (Major Depression Inventory). Analysis was by intention-to-treat, using linear mixed models. Results: 303 patients were assessed for eligibility of whom 165 patients (mean age 50 years (SD 13) with a mean Oswestry Disability Index score of 42 (SD 11)) were randomly allocated (1:1 ratio) to the integrated programme (n = 82) or the existing programme (n = 83). The mean difference (integrated programme minus existing programme) in disability was –0.53 (95% CI –4.08 to 3.02); p = 0.770). No statistically significant differences were found in the secondary outcomes. Conclusion: The integrated programme was not more effective in reducing long-term disability in patients with chronic low back pain than the existing programme.

Efficacy and Safety of Ultrasound-Guided Radiofrequency Treatment for Chronic Pain in Patients with Knee Osteoarthritis: A Systematic Review and Meta-Analysis.

Background Knee osteoarthritis (KOA) is a common degenerative disease associated with joint dysfunction and pain. Ultrasound-guided radiofrequency (RF) may be a promising therapy in the treatment of chronic pain for KOA patients. Objective To evaluate the efficacy and safety of ultrasound-guided RF treatment for chronic pain in patients with KOA. Design A systematic review was conducted, and a meta-analysis was carried out when possible. Setting. We examined the studies evaluating the clinical efficiency of ultrasound-guided RF on chronic pain in KOA population. Method A systematic review for the efficacy and safety of ultrasound-guided RF treatment for pain management of KOA patients was carried out in PubMed, EMBASE, Cochrane Library, Web of Science, Wanfang Data, and China National Knowledge Infrastructure (CNKI) from the date of inception to February 2020, and a meta-analysis was conducted. The primary outcomes of pain intensity (visual analogue scale or numerical rating scale) and knee function [the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC)] were evaluated from baseline to various follow-up times by random-effects model. Heterogeneity was assessed by I2 statistic and the potential sources of heterogeneity by subgroup and metaregression analyses, respectively. Results Eight publications with 256 patients were included in the meta-analysis. RF could relieve pain with −4.196 of pooled mean difference and improve knee function by decreasing 23.155 points in WOMAC. Three patients had ecchymosis, two with hypoesthesia and one with numbness after the procedure, and improved within 6 months. Furthermore, study design and treatment target were the sources of heterogeneity by subgroup and metaregression analyses, accounting for 37% and 74% of variances, respectively. Target of genicular nerve achieved better pain relief than intra-articular or sciatic nerve. Sensitivity analysis showed that removal of any single study was unlikely to overturn the findings. Limitations. There were some limitations in the study. Firstly, the small number of relevant studies limited the confidence level of the meta-analysis. Also, the significant heterogeneity may not be explained due to the limited data. Secondly, the direct comparison of two different guidance methods (ultrasound vs. fluoroscopy) for RF therapy is lacking. In addition, the outcomes were blindly assessed in the meta-analysis from all studies according to evaluation of bias, which could affect the reality of the data. Finally, most of the studies only provided short follow-up times, so we could not analyze the long-term effectiveness of ultrasound-guided RF in the treatment of patients with KOA. Conclusions Ultrasonography is an effective, safe, nonradiative, and easily applicable guidance method for RF in pain relief and functional improvement in KOA patients.

Embedding pain neuroscience education in the physical therapy management of patients with chronic plantar fasciitis: a prospective case series

ABSTRACT Objectives The purpose of this case series was to describe the effects of a biopsychosocial approach that embeds pain neuroscience education (PNE) within physical therapy for improving foot and ankle function, pain, and psychosocial factors in patients with chronic plantar fasciitis. Methods Seven female patients (mean [SD] age = 49.0 [11.4] years) receiving physical therapy for chronic plantar fasciitis were enrolled. Along with formal physical therapy, patients received six 15-minute PNE sessions. Knowledge of pain neuroscience was assessed before and after PNE with the Revised Neurophysiology of Pain Questionnaire. Patients completed questionnaires for foot and ankle function (Activities of Daily Living subscale of the Foot and Ankle Ability Measure), pain intensity (Numeric Rating Scale), pain catastrophizing (Pain Catastrophizing Scale), and fear of movement (Tampa Scale for Kinesiophobia) at baseline (before treatment) and 6 and 12 weeks. Local and remote pain sensitivity was assessed using a pressure algometer at baseline and 6 weeks. Results Patients attended a mean (range) of 8.7 (7 to 12) physical therapy sessions over a mean (range) of 46.7 (42 to 56) days. After PNE, six (86%) patients demonstrated increased knowledge of pain neuroscience. At 12 weeks, six (86%) patients met or exceeded minimally clinically important difference (MCID) for foot and ankle function and pain. Five (71%) patients met or exceeded MCID for pain catastrophizing and fear of movement. Local pain sensitivity was reduced in six (86%) patients. Conclusions Physical therapy integrating PNE is potentially beneficial for patients with chronic plantar fasciitis. Future studies should examine the efficacy of PNE in randomized trials with larger representative samples.

Alveolar iodine tampon packing after impacted third molar surgery improves oral health\u2013related quality of life and postoperative sequela: a randomized study

ObjectiveThe aim of this study was to evaluate the effect of an iodine tampon on postoperative discomfort after surgical removal of a mandibular third molar.Material and methodsPatients were randomly assigned to two groups: one group received an alveolar iodine-containing tampon in the extraction socket (N = 44), and the other group used a disposable syringe (Monoject®) to rinse the wound (N = 43). Postoperative discomfort was assessed with the Oral Health Impact Profile-14 (OHIP-14) questionnaire, Pain Intensity Numerical Rating Scale (PI-NRS), and questions about self-care and discomfort.ResultsThis study included 87 patients (52 women and 35 men) with an average age of 26.47 years (SD, 6.36). The mean OHIP-14 sum scores were significantly lower in the iodine tampon group compared with the Monoject® syringe group. Mean PI-NRS scores significantly differed between the iodine tampon group (3.33; SE, 0.27) and Monoject® syringe group (4.46; SE, 0.27) (F (1, 85) = 8.16, p < 0.01), with no interaction effect between time and PI-NRS (F (6, 510) = 1.26, p = 0.28). Patients in the iodine tampon group reported less postoperative discomfort.ConclusionsInsertion of an iodine-containing tampon in the postoperative socket reduced the pain and impact on oral health-related quality of life during the first postoperative week and positively influenced postoperative sequelae.

Treatment of a Large Cohort of Veterans Experiencing Musculoskeletal Disorders with Spinal Cord Stimulation in the Veterans Health Administration: Veteran Characteristics and Outcomes.

ObjectiveSpinal cord stimulator (SCS) implantation is used to treat chronic pain, including painful musculoskeletal disorders (MSDs). This study examined the characteristics and outcomes of veterans receiving SCSs in Veterans Health Administration (VHA) facilities.MethodsThe sample was drawn from the MSD Cohort and limited to three MSDs with the highest number of implants (N=815,475). There were 1490 veterans with these conditions who received SCS implants from 2000 to 2012, of which 95% (n=1414) had pain intensity numeric rating scale (NRS) data both pre- and post-implant.ResultsVeterans who were 35–44 years old, White, and married reported higher pain NRS ratings, had comorbid inclusion diagnoses, had no medical comorbidities, had a BMI 25–29.9, or had a depressive disorder diagnosis were more likely to receive an SCS. Veterans 55+ years old or with an alcohol or substance use disorder were less likely to receive an SCS. Over 90% of those receiving an SCS were prescribed opioids in the year prior to implant. Veterans who had a presurgical pain score ≥4 had a clinically meaningful decrease in their pain score in the year following their 90-day recovery period (Day 91–456) greater than expected by chance alone. Similarly, there was a significant decrease in the percent of veterans receiving opioid therapy (92.4% vs 86.6%, p<0.0001) and a significant overall decrease in opioid dose [morphine equivalent dose per day (MEDD) =26.48 vs MEDD=22.59, p<0.0003].ConclusionResults offer evidence of benefit for some veterans with the examined conditions. Given known risks of opioid therapy, the reduction is an important potential benefit of SCS implants.

Association Between Physical Activity, Weight Loss, Anxiety, and Lumbopelvic Pain in Postpartum Women

ObjectiveLumbopelvic pain (LBPP) affects 45% to 81% of pregnant women, and 25% to 43% of these women report persistent LBPP beyond 3 months after giving birth. The objective of this study was to investigate the association of physical activity, weight status, anxiety, and evolution of LBPP symptoms in postpartum women. MethodsThis was a prospective observational cohort study with 3 time-point assessments: baseline (T0), 3 months (T3), and 6 months (T6). Women with persistent LBPP 3 to 12 months after delivery were recruited. At each time point, pain disability was assessed with the Pelvic Girdle Questionnaire and the Oswestry Disability Index (ODI), physical activity with Fitbit Flex monitors, and anxiety with the French-Canadian version of the State-Trait Anxiety Inventory. Weight was recorded using a standardized method. Pain intensity (numerical rating scale, 0-100) and frequency were assessed using a standardized text message on a weekly basis throughout the study. ResultsThirty-two women were included (time postpartum: 6.6 ± 2.0 months; maternal age: 28.3 ± 3.8 years; body weight: 72.9 ± 19.1 kg), and 27 completed the T6 follow-up. Disability, pain intensity, and pain frequency improved at T6 (P < .001). Participants lost a mean of 1.9 ± 4.5 kg at T6, and this weight loss was correlated with reduction in LBPP intensity (r = 0.479, P = .011) and LBPP frequency (r = 0.386, P = .047), Pelvic Girdle Questionnaire score (r = 0.554, P = .003), and ODI score (r = 0.494, P = .009). Improvement in ODI score at T6 was correlated with the number of inactive minutes at T3 (r = −0.453, P = .026) and T6 (r = −0.457, P = .019), and with daily steps at T6 (r = 0.512, P = .006). ConclusionWeight loss is associated with positive LBPP symptom evolution beyond 3 months postpartum, and physical activity is associated with reduction in pain disability.

Pain across traumatic injury groups: A National Institute on Disability, Independent Living, and Rehabilitation Research model systems study.

Pain is a common problem after traumatic injury. We describe pain intensity and interference at baseline and 1 year postinjury in burn, traumatic brain injury (TBI), and spinal cord injury (SCI) survivors and compare them with the general population (GP). We tested a custom Patient Reported Outcomes Measurement Information System (PROMIS) pain interference short form developed for use in trauma populations. We administered a pain intensity numerical rating scale and custom PROMIS pain interference short forms at baseline and/or 1 year postinjury from participants (≥18 years) at three Model System projects (burn, TBI, and SCI). Scores were compared across injury groups and pain intensity levels, and to the GP. Reliability and floor and ceiling effects of the custom PROMIS pain measures were calculated. Participants (burn, 161; TBI, 232; SCI, 134) responded to the pain intensity and/or pain interference measures at baseline (n = 432), 1 year (n = 288), or both (n = 193). At baseline, pain interference and intensity were both significantly higher in all three groups than in the GP (all p < 0.01). At 1 year, average pain intensity in SCI and burn (p < 0.01) participants was higher than the GP, but only SCI participants reported higher pain interference (p < 0.01) than the GP. Half of all participants reported clinically significant pain interference (55 or higher) at baseline and one third at 1 year. Reliability of the custom pain interference measure was excellent (>0.9) between T-scores of 48 and 79. The custom pain interference short forms functioned well and demonstrated the utility of the custom PROMIS pain interference short forms in traumatic injury. Results indicate that, for many people with burn, TBI and SCI, pain remains an ongoing concern long after the acute injury phase is over. This suggests a need to continue to assess pain months or years after injury to provide better pain management for those with traumatic injuries. Epidemiologic/Therapeutic study, level IV.

Factors Associated With Posttraumatic Stress Disorder Among Veterans of Recent Wars Receiving Veterans Affairs Chiropractic Care

ObjectivesPost-traumatic stress disorder (PTSD) is thought to complicate pain management outcomes, which is consistent with the impact of other psychosocial factors in the biopsychosocial model of pain. This study aimed to identify patient sociodemographic and clinical characteristics associated with PTSD prevalence among veterans of Operations Enduring Freedom/Iraqi Freedom/New Dawn (OEF/OIF/OND) who received Veterans Affairs (VA) chiropractic care. MethodsA cross-sectional analysis of electronic health record data from a national cohort study of OEF/OIF/OND veterans with at least 1 visit to a VA chiropractic clinic from 2001 to 2014 was performed. The primary outcome measure was a prior PTSD diagnosis. Variables including sex, race, age, body mass index, pain intensity, alcohol and substance use disorders, and smoking status were examined in association with PTSD diagnosis using logistic regression. ResultsWe identified 14,025 OEF/OIF/OND veterans with at least 1 VA chiropractic visit, with a mean age of 38 years and 54.2% having a diagnosis of PTSD. Male sex (adjusted odds ratio [OR] = 1.23, 95% CI = 1.11-1.37), younger age (OR = 0.99, CI = 0.98-0.99), moderate-to-severe pain intensity (numerical rating scale ≥ 4) (OR = 1.72, CI = 1.59-1.87), body mass index ≥ 30 (OR = 1.34, CI = 1.24-1.45), current smoking (OR = 1.32, CI = 1.20-1.44), and having an alcohol or substance use disorder (OR = 4.51, CI = 4.01-5.08) were significantly associated with a higher likelihood of PTSD diagnosis. ConclusionPost-traumatic stress disorder is a common comorbidity among OEF/OIF/OND veterans receiving VA chiropractic care and is significantly associated with several patient characteristics. Recognition of these factors is important for the appropriate diagnosis and management of veterans with PTSD seeking chiropractic treatment for pain conditions.

Testosterone replacement therapy of opioid-induced male hypogonadism improved body composition but not pain perception: a double-blind, randomized, and placebo-controlled trial.

Hypogonadism is prevalent during opioid treatment, but the effect of testosterone replacement treatment (TRT) on body composition, pain perception, and adrenal function is unclear. To measure changes in body composition, pain perception, quality of life, and adrenal function after TRT or placebo in opioid-treated men with chronic non-malignant pain. Double-blind, placebo-controlled study in 41 men (>18 years) with total testosterone <12 nmol/L were randomized to 24 weeks TRT (Testosterone undecanoate injection three times/6 months, n = 20) or placebo (placebo-injections, n = 21). Body composition (lean body mass and fat mass assessed by DXA), clinical pain intensity (numerical rating scale), and experimental pain perception (quantitative sensory assessment), quality of life (SF36), and adrenocorticotrophic hormone (ACTH) test. Data were presented as median (quartiles). Mann-Whitney tests were performed on delta values (24-0 weeks) between TRT and placebo. The median age was 55 years (46; 59) and total testosterone before intervention was 6.8 (5.0; 9.3) nmol/L. TRT was associated with change of testosterone levels: 12.3 (7.0; 19.9) nmol/L (P < 0.001 vs placebo), increased lean body mass: 3.6 (2.3; 5.0) kg vs 0.1 kg (-2.1; 1.5) during TRT vs placebo and decreased total fat mass: -1.2 (-3.1; 0.7) kg vs 1.2 kg (-0.9; 2.5) kg, both P < 0.003. Changed pain perception, SF36, and ACTH-stimulated cortisol levels were non-significantly changed during TRT compared with placebo. Six months of TRT improved body composition in men with opioid-induced hypogonadism without significant changes in outcomes of pain perception, quality of life, or adrenal function.

A very early clinical response to treatment with the Janus kinase inhibitor tofacitinib in patients with active rheumatoid arthritis: the dynamics of pain and central sensitization elements

Janus kinase (JK) inhibitors block the intracellular signaling pathways that are responsible for the synthesis of proinflammatory cytokines and mediators, which in turn cause the activation of pain receptors and central sensitization (CS). It is suggested that JK inhibitors can rapidly eliminate pain and reduce the severity of CS.Objective: to evaluate the effect of the JK inhibitor tofacitinib (TOFA) on the intensity of pain and the signs of CS in patients with active rheumatoid arthritis (RA) at 7 and 28 days after therapy initiation.Patients and methods. A study group consisted of 39 patients (79.5% female) (mean age 50.9±11.1 years) with RA (DAS28 5.8±0.6). Of these, 89.7% were seropositive for rheumatoid factor; 82.0% took methotrexate and 18.0% received leflunomide. All the patients were prescribed TOFA 5 mg twice daily due to the inefficacy or intolerance of biological agents. The investigators estimated pain intensity using a Brief Pain Inventory (BPI), rated the presence of a neuropathic pain component (NPC) with the PainDETECT questionnaire, and assessed the signs of CS with the Central Sensitization Inventory (CSI) during the first 4 weeks after TOFA administration.Results and discussion. The patients initially experienced moderate or severe pain (the mean scores of 5.33±2.51 on the numerical rating scale (NRS) included in BPI); 53.8% had signs of CS (CSI scores of ≥40); 17.9% had signs of a NPC (PainDETECT scores of &gt;18). Already on day 7 after the start of TOFA administration, there was a statistically significant decrease in the mean NRS pain intensity scores to 4.06±2.2 (p=0.01) and by 29.4±17.9%, as shown by the patient's assessment of the analgesic effect of therapy (BPI), as well as the severity of CS, namely a decrease in the mean NRS pain score to 35.9±11.2 (p=0.01). On 28 days, the effect became better: there was a reduction in the level of NRS pain to 2.32±1.57 (p&lt;0.001), in pain according to the patient's assessment of the analgesic effect of therapy to 43.6±29.6%; in the median PainDETECT score to 2.5 [0; 8.7] (p&lt;0.001); and in CSI scores to an average of 26.4±13.9 (p &lt;0.001). No serious adverse reactions were noted.TOFA has a rapid analgesic effect, which allows it to be considered as a chooser for pathogenetic therapy in patients with active RA and severe pain, especially in the presence of CS signs and secondary fibromyalgia. Undoubtedly, large-scale, long-term controlled studies with a wider range of estimated parameters are required to clarify the therapeutic potential of TOFA in this patient category. The limitation of this investigation was its open observer design pattern.Conclusion. The use of the JK inhibitor TOFA can achieve a rapid analgesic effect, inter alia due to its effect on CS and NPC.

Insomnia and caregiver burden in chronic pain patients: A cross-sectional clinical study.

Insomnia is a major comorbid symptom of chronic pain and is likely to affect caregiver burden. This cross-sectional study investigated the association between insomnia in chronic pain patients and family caregiver burden. Participants were 60 patients with chronic pain of ≥3 months duration. Demographic and clinical information were collected using the Athens Insomnia Scale (AIS), the Pain Disability Assessment Scale (PDAS), the Hospital Anxiety and Depression Scale (HADS), and a pain intensity numerical rating scale (NRS). Family members who accompanied chronic pain patients to hospital completed the Zarit Burden Interview (ZBI). Univariate regression analysis and multiple regression analysis were conducted to clarify the associations between ZBI scores and total/subscale AIS scores. Covariates were age; sex; pain duration; and scores on the PDAS, HADS anxiety subscale, HADS depression subscale, and NRS. Insomnia was independently associated with ZBI scores [β: 0.27, 95% confidence interval (CI): 0.07–0.52, p = 0.001]. Scores on the AIS subscale of physical and mental functioning during the day were significantly associated with ZBI scores (β: 0.32, 95% CI: 0.05–0.59, p = 0.007). In conclusion, the findings suggest that in chronic pain patients, comorbid insomnia and physical and mental daytime functioning is associated with family caregiver burden independently of pain duration, pain-related disability, and pain intensity.

Does the Degree of Trunk Bending Predict Patient Disability, Motor Impairment, Falls, and Back Pain in Parkinson's Disease?

Background: Postural abnormalities in Parkinson's disease (PD) form a spectrum of functional trunk misalignment, ranging from a “typical” parkinsonian stooped posture to progressively greater degrees of spine deviation.Objective: To analyze the association between degree of postural abnormalities and disability and to determine cut-off values of trunk bending associated with limitations in activities of daily living (ADLs), motor impairment, falls, and back pain.Methods: The study population was 283 PD patients with ≥5° of forward trunk bending (FTB), lateral trunk bending (LTB) or forward neck bending (FNB). The degrees were calculated using a wall goniometer (WG) and software-based measurements (SBM). Logistic regression models were used to identify the degree of bending associated with moderate/severe limitation in ADLs (Movement Disorders Society Unified PD Rating Scale [MDS-UPDRS] part II ≥17), moderate/severe motor impairment (MDS-UPDRS part III ≥33), history of falls (≥1), and moderate/severe back pain intensity (numeric rating scale ≥4). The optimal cut-off was identified using receiver operating characteristic (ROC) curves.Results: We found significant associations between modified Hoehn & Yahr stage, disease duration, sex, and limitation in ADLs, motor impairment, back pain intensity, and history of falls. Degree of trunk bending was associated only with motor impairment in LTB (odds ratio [OR] 1.12; 95% confidence interval [CI], 1.03–1.22). ROC curves showed that patients with LTB of 10.5° (SBM, AUC 0.626) may have moderate/severe motor impairment.Conclusions: The severity of trunk misalignment does not fully explain limitation in ADLs, motor impairment, falls, and back pain. Multiple factors possibly related to an aggressive PD phenotype may account for disability in PD patients with FTB, LTB, and FNB.

Depression and Functional Outcomes in Patients Presenting to the Emergency Department With Low Back Pain

Low back pain (LBP) is a common reason for patients to present to emergency departments (EDs). Our objective was to describe the associations between depressive symptoms, pain severity, and functional impairment up to 3months after initial ED presentation for LBP. We performed a secondary analysis on an observational cohort of adult patients from a high-volume, urban ED. Initial depressive symptoms (Patient Health Questionnaire-9) and disability (Roland Morris Disability Questionnaire) were collected in person at the time of initial ED visit and by telephone at 1-week and 3-month follow-ups. Pain intensity (Numeric Rating Scale) was collected at 1-week and 3-month follow-ups. Our primary goal was to determine the associations between initial depressive symptoms and pain intensity and disability scores at 3months. We also investigated the associations of initial and 3-month change in depressive symptoms with change in disability score from initial presentation to 3months and change in pain score from 1week to 3months. Of the 674 patients initially enrolled, 362 patients had complete depressive symptom, pain, and disability data and were included in the final analysis. Those with higher levels of intake depressive symptoms had worse pain intensity (B=0.14, 95% confidence interval [CI]=0.08 to 0.21) and disability (0.46, 95% CI=0.30 to 0.62) severity at 3months, with less improvement in disability over the 3months (B=0.22, 95% CI=0.05 to 0.40). Furthermore, those with worsening depressive symptoms over the 3-month study period experienced less improvement in pain intensity (B=0.10, 95% CI=0.05 to 0.17) and disability (B=0.84, 95% CI=0.66 to 1.02) over the same time frame. Except for a slight strengthening of the association between initial depressive symptom severity and 3-month pain score among patients with no prior LBP episodes, history of prior LBP episodes did not moderate these relationships. Significant positive temporal associations exist between initial severity and 3-month progression of depressive symptoms and 3-month pain intensity and disability outcomes for ED patients with LBP. Future work is needed to investigate whether behavioral interventions initiated from the ED may mitigate the incidence and severity of LBP-related chronic pain and functional impairments.

Early Self-directed Home Exercise Program After Anterior Cervical Discectomy and Fusion: A Pilot Study.

Pilot randomized controlled trial. To examine the acceptability and preliminary safety and outcome effects of an early self-directed home exercise program (HEP) performed within the first 6 weeks after anterior cervical discectomy and fusion (ACDF). Little is known regarding optimal postoperative management after ACDF. Thirty patients (mean ± standard deviation, age = 50.6 ± 11.0 years, 16 women) undergoing ACDF were randomized to receive an early HEP (n = 15) or usual care (n = 15). The early HEP was a 6-week self-directed program with weekly supportive telephone calls to reduce pain and improve activity. Treatment acceptability was assessed after the intervention period (6 weeks after surgery). Safety (adverse events, radiographic fusion, revision surgery) was determined at routine postoperative visits. Disability (Neck Disability Index), pain intensity (Numeric Rating Scale for neck and arm pain), physical and mental health (SF-12), and opioid use were assessed preoperatively, and at 6 weeks and 6 and 12 months after surgery by an evaluator blinded to group assignment. Participants reported high levels of acceptability and no serious adverse events with the early HEP. No difference in fusion rate was observed between groups (P > 0.05) and no participants underwent revision surgery. The early self-directed HEP group reported lower 6-week neck pain than the usual care group (F = 3.3, P = 0.04, r = 0.3, mean difference = -1.7 [-3.4; -0.05]) and lower proportion of individuals (13% vs. 47%) using opioids at 12 months (P = 0.05). No other between-group outcome differences were observed (P > 0.05). An early self-directed HEP program was acceptable to patients and has the potential to be safely administered to patients immediately after ACDF. Benefits were noted for short-term neck pain and long-term opioid utilization. However, larger trials are needed to confirm safety with standardized and long-term radiograph assessment and treatment efficacy. 2.

The Effect of Early Limited Activity after Bipedicular Percutaneous Vertebroplasty to Treat Acute Painful Osteoporotic Vertebral Compression Fractures

Although percutaneous vertebroplasty (PVP) can effectively relieve the pain for patients with acute osteoporotic vertebral compression fractures (OVCFs), many patients still complain of mild back pain in the early postoperative period. The aim of this study was to assess the effect of early limited activity (LA) on prognosis after bipedicular small-cement-volume (i.e., PVP) to treat single-segment acute OVCFs. A prospective study and retrospective observations were performed on 125 patients with a minimum of 1 year of follow-up. A university hospital orthopedics and pathology departments. All patients were allocated into an LA group (n = 64) and an unlimited activity group (ULA group, n = 61). Patients in the LA group were suggested to keep time of off-bed activity < 4 hours per day in the first 3 weeks postoperatively. Patients in the ULA group did not limit activity. The demographic, clinical, and radiologic outcomes were assessed, such as pain intensity Numeric Rating Scale (NRS-11) and vertebral height ratio (i.e., fractured vertebral height/adjacent nonfractured vertebral height). Based on outcomes following surgery, all patients were classified as responders (NRS-11 score 1-day postoperation < 50% of preoperative NRS-11 score) or low responders (NRS-11 score 1-day postoperation >= 50% of preoperative NRS-11 score). The demographic results and complications were similar. In the LA group, NRS-11 scores at 1 and 3 months postoperation respectively were 2.23 ± 0.42 and 1.46 ± 0.40, and corresponding scores respectively were 2.85 ± 0.80 and 1.73 ± 0.77 in the ULA group, and there was a difference in the 2 groups in both time points (P < 0.05). At 12 months postoperation, anterior and middle vertebral height ratio respectively were 78.42% ± 3.52% and 82.37% ± 3.49% in the LA group, which were higher than 76.87% ± 3.68% and 81.10% ± 3.31% in the ULA group (P < 0.05). Thirty-two cases were low responders. Among those, NRS-11 scores at 1 and 3 months postoperation respectively were 2.29 ± 0.45 and 1.53 ± 0.46 in the LA group, which were lower than 3.67 ± 0.80 and 2.56 ± 0.79 in the ULA group (P < 0.05), and at 12 months postoperation, anterior vertebral height ratio was 79.81% ± 3.25% in the LA group and 75.60% ± 3.50% in the ULA group (P < 0.05). First, some patients lacked the results of bone mineral density during follow-up; second, the limited time in our study was chosen from our previous working experience, which may lack an objective basis; third, NRS-11 is solely used as an indicator of clinical outcomes in our study; finally, our next studies can increase the sample size to improve the clinically difference. LA in the early period after PVP can help patients achieve more pain relief postoperatively and maintain better vertebral shape, especially for low responders.
