A Retrospective Evaluation of Operative and Postoperative Outcomes in Patients with Spinal Metastases from a Single Center to Compare Vertebrectomy with Combined Vertebrectomy and Radiofrequency Ablation.

BACKGROUND This retrospective study was conducted at a single center and aimed to evaluate operative and postoperative outcomes in patients with spinal metastases using vertebrectomy and combined vertebrectomy and radiofrequency ablation (RFA). MATERIAL AND METHODS Patients diagnosed with spinal metastases between April 2009 and March 2016 (n=49) included patients who underwent vertebrectomy (n=26) and patients who underwent combined vertebrectomy and RFA (n=23). The characteristics of the 2 groups were similar in primary tumor types, comorbidities, Tomita score, vertebral involvement, preoperative bone pain, and neurologic deficit. RESULTS The results showed for the both groups that the visual analog scale (VAS) pain score was significantly decreased (P<0.05) and the neurological status was improved after treatment. Compared with the control group (vertebrectomy only), the combination group (combined vertebrectomy and RFA) had less intraoperative blood loss (P=0.002) and shorter operation time (P<0.001). The recurrence rate was lower (P=0.003) in the patients who received combined treatment, and the period of local recurrence was prolonged (P=0.030) in the combination group. CONCLUSIONS This retrospective study showed that the selective use of combined vertebrectomy and RFA significantly reduced surgical time and blood loss, improved recovery of neurologic deficit, and reduced the tumor recurrence rate in patients with spinal metastases.

Solitary bone plasmacytoma of spine with involvement of adjacent disc space: A case report.

RATIONALE: Solitary bone plasmacytoma (SBP) is a rare manifestation of plasma cell tumor. Although axial skeleton is the most frequently affected site of SBP, adjacent disc space involvement is rare. Herein we report a case of SBP in thoracic vertebra with involvement of adjacent disc space. PATIENT CONCERNS: A 57-year-old male presented with a 2-year history of intermittent back pain with activity. The patient's back pain intensity with activity was a score of 5 of the 10-point visual analog scale). DIAGNOSES AND INTERVENTION: The patient underwent a posterior fusion procedure from T6 to T10, and an open biopsy of the vertebral lesion confirmed that final diagnosis of SBP. The patient received postoperative radiotherapy with a total of 4000 Gy to the T7-T9 vertebral levels over a 20-day period. OUTCOMES: Following radiotherapy, the patient's pain intensity was reduced to the visual analog scale score of 1 at the 6-month follow-up. LESSONS: SBP lacks typical clinical symptoms, and the accurate diagnosis before clinical intervention remains challenging. Due to the disc involvement, SBP often manifests as spinal infection. Hence, differential diagnosis in spinal lesions involving the disc should include SBP.

Initial Presentation of Pain in Patients with Fibromyalgia.

BACKGROUND: Fibromyalgia is characterized by diffuse musculoskeletal pain at the time of diagnosis, but many patients report their initial symptoms as being focal or local. OBJECTIVES: To evaluate, prospectively, the initial location of body pain in recently diagnosed patients with fibromyalgia. METHODS: Non-selected patients from the rheumatology clinic who were recently diagnosed with fibromyalgia (≤ 2 years) with symptoms of ≤ 4 years participated in our study. Demographic and clinical parameters were documented, as was the initial location of pain they had experienced. Sub-analysis of data according to gender and ethnicity was conducted using chi-squire test. RESULTS: The study comprised 155 patients. Mean age was 39.8 ± 11.7 years; 85% were female. Mean duration of symptoms was 2.11 years and of diagnosis was 0.78 years. Six patients (3.9%) reported initial symptoms of pain as being diffuse from the start, 10 (6.5%) could not remember the location of their initial symptoms, and 139 (90%) reported initial focal pain. Hands were reported as the initial area of pain for 25.2% of the patients, 19.4% reported the back, and 11% reported both trapezial areas as the initial area of pain. In 90% of the patients (excluding patients with back, abdominal, or chest pain) the initial symptoms were bilateral and symmetrical. No significant difference in initial presentation was found among different gender or ethnic groups. CONCLUSIONS: Pain in fibromyalgia patients usually presents as focal and symmetrical. Bilateral hand pain, followed by back pain, was the most common reported area of initial pain among fibromyalgia patients.

A randomized double blinded placebo controlled study to evaluate motor unit abnormalities after experimentally induced sensitization using capsaicin.

Central sensitization is a condition that represents a cascade of neurological adaptations, resulting in an amplification of nociceptive responses from noxious and non-noxious stimuli. However, whether this abnormality translates into motor output and more specifically, ventral horn abnormalities, needs to be further explored. Twenty healthy participants aged 20-70 were randomly allocated to topical capsaicin or a placebo topical cream which was applied onto their left upper back to induce a transient state of sensitization. Visual analogue scale (VAS) ratings of pain intensity and brush allodynia score (BAS) were used to determine the presence of pain and secondary allodynia. Surface electromyography (sEMG) and intramuscular electromyography (iEMG) were used to record motor unit activity from the upper trapezius and infraspinatus muscles before and twenty minutes after application of capsaicin/placebo. Motor unit recruitment and variability were analyzed in the sEMG and iEMG, respectively. An independent t-test and Kruskal-Wallis H test were performed on the data. The sEMG results demonstrated a shift in the motor unit recruitment pattern in the upper trapezius muscle, while the iEMG showed a change in motor unit variability after application of capsaicin. These results suggest that capsaicin-induced central sensitization may cause changes in ventral horn excitability outside of the targeted spinal cord segment, affecting efferent pathway outputs. This preclinical evidence may provide some explanation for the influence of central sensitization on changes in movement patterns that occur in patients who have pain encouraging of further clinical investigation.Clinical Trials registration number: NCT04361149; date of registration: 24-Apr-2020.

Surgical Stabilization for Patients with Mechanical Back Pain Secondary to Metastatic Spinal Disease is Associated with Improved Objective Mobility Metrics: Preliminary Analysis in a Cohort of 26 Patients.

OBJECTIVES: To investigate the effect of surgical stabilization for patients with metastatic spinal disease on objective mobility metrics. METHODS: A retrospective chart review identified patients who had mechanical back pain from metastatic spinal disease and underwent spinal stabilization during 2017. Mobility metrics, the Activity Measure for Post-Acute Care (AM-PAC) inpatient mobility short form (IMSF) and the Johns Hopkins Highest Level of Mobility (JH-HLM), were reviewed. RESULTS: A total of 26 patients were included in the analysis with median hospital stay of 8 days. Preoperative JH-HLM scores were available for 17 patients with a mean score of 5.4, increasing to mean score of 6.6 at last follow-up (P = 0.036). Preoperative AM-PAC IMSF scores were available for 14 patients with a mean score of 19.4, decreasing slightly to a mean score of 18.7 at last follow-up (P = 0.367). Last follow-up with mobility metrics occurred a median of 6.5 days postoperatively (range: 3-66 days). Multivariable analysis showed that American Spinal Injury Association and Karnofsky Performance Status scores were significantly associated with both JH-HLM and AM-PAC mobility scores at last follow-up. A higher JH-HLM or AM-PAC score was significantly associated with direct home discharge and a higher AM-PAC score was associated with shorter hospital stay. CONCLUSIONS: Surgical stabilization for patients with mechanical back pain secondary to metastatic spinal disease might lead to an objective improvement in JH-HLM score. JH-HLM and AM-PAC scores may be correlated with length of hospital stay and discharge disposition. Future studies are encouraged to further characterize the role of these mobility metrics in the management plan of these patients.

Indications for Lumbar Fusion in the Skeletally Mature Adolescent: How to Address Oblique Takeoff and Limb Length Discrepancy.

BACKGROUND: Indications for posterior spinal fusion (PSF) with segmental spinal instrumentation (SSI) of a scoliotic deformity in a skeletally mature individual are based on the balance between the anticipated benefit of stopping future curve progression and the potential downside of loss of spinal mobility. The dilemma regarding PSF with SSI in the adolescent population is exacerbated by the patient's participation in athletics requiring flexibility and motion of the spine, the location of the curve, the presence of pelvic obliquity, and the impact of a limb length discrepancy. The purpose of this review is to discuss the potential advantages and disadvantages of PSF with SSI in a hypothetical skeletally mature adolescent with a 45-degree lumbar curve, pelvic obliquity, and limb length discrepancy. DISCUSSION: Natural history studies of untreated adolescent idiopathic scoliosis (AIS) have shown that slow curve progression throughout adulthood is likely. Adults with untreated AIS may also have more back pain and dissatisfaction with their appearance. Although the clinical and radiographic outcomes of PSF with SSI are excellent, patients should be counseled about the impact of fusing the lumbar spine on back pain, decreased spinal mobility, and potential inability to return to athletics at the same level. Adults who undergo surgery for AIS have greater operative morbidity and number of levels fused compared with adolescents. CONCLUSION: These factors should be presented when discussing observation versus PSF with SSI with patients and families. Delaying surgery until formal athletic participation is complete should be considered.

Primary care physician perspectives on screening for axial spondyloarthritis: A qualitative study.

BACKGROUND: Many patients with axial spondylarthritis (axSpA) experience lengthy diagnostic delays upwards of 14 years. (5-14 years). Screening tools for axSpA have been proposed for use in primary care settings, but whether this approach could be implemented into busy primary care settings remains unknown. OBJECTIVE: To solicit feedback from primary care physicians regarding questions from the Inflammatory Back Pain Assessment: the Assessment of Spondyloarthritis International Society (ASAS) Expert Criteria and gain insight about barriers and facilitators for implementing axSpA screening in primary care. METHODS: Guided by Consolidated Criteria for reporting Qualitative Research (COREQ-criteria), we recorded, transcribed, and analyzed in-depth interviews with eight family medicine physicians and ten internists (purposeful sampling) using immersion/crystallization techniques. RESULTS: Few physicians reported awareness of existing classification criteria for axSpA, and many reported a lack of confidence in their ability to distinguish between inflammatory and mechanical back pain. From three domains, 10 subthemes emerged: 1) typical work-up of axSpA patients in primary care, with subthemes including the clues involved in work-up and role of clinical examinations for axSpA; 2) feedback on questions from the Inflammatory Back Pain Assessment: ASAS Expert Criteria, with subthemes to evaluate contents/questions of a potential screening tool for axSpA; and 3) implementation of the screening tool in primary care settings, with subthemes of perceived barriers including awareness, time, other conditions to screen, rare disease, and lack of structured questionnaire for back pain and perceived facilitators including workflow issues and awareness. CONCLUSIONS: Primary care physicians believed that an improved screening instrument and a strong evidence-base to support the need for screening for axSpA are required. The implementation of axSpA screening into a busy primary care practice requires integration into the practice workflow, with use of technology suggested as a possible way to improve efficiency.

The effect of smoking on back pain intensity in rehabilitated patients treated conservatively and surgically for discopathy.

INTRODUCTION: Back pain is now a very common phenomenon. It is caused by various pathologies in the area of the motor unit of the spine. These changes can cause pressure on the nerve structures within the spinal canal, resulting in various ailments. Pain is the most common symptom. In most cases, patients are qualified for conservative management. In the case of neurological deficits, the patient is qualified for spinal surgery. Unfortunately, surgical treatment is not always 100% effective therapy method. Moreover, many external factors, such as smoking for instance, can affect the process of tissue healing and decide on the time of recovery. OBJECTIVE: The aim of the study was to assess the impact of smoking on back pain intensity in rehabilitated patients with discopathy treated conservatively and surgically. MATERIAL AND METHODS: The study included 41 patients after surgical treatment (9 smokers) and 96 patients (20 smokers) undergoing conservative therapy for back pain due to discopathy. All patients underwent a multidirectional rehabilitation programme at the Department of Rehabilitation and Physical Medicine of the Medical University in Lódz. RESULTS: The Laitinen scale was used to assess the patients' pain. Rehabilitation of patients with back pain due to discopathy had a significant analgesic effect (p <0.0001). Furthermore, there was observed a statistically significant effect of smoking on the level of pain intensity on the Laitinen scale in the group of patients who underwent surgery (p <0.0469). The smokers operated on had significantly worse results. CONCLUSIONS: 1) Complex rehabilitation of patients with back syndrome pain due to discopathy demonstrated significant analgesic effectiveness. 2) Smoking significantly worsens the results of the therapy in patients who underwent surgery.

Clinical Manifestations and Outcomes in Disease-Modifying Antirheumatic Drug-Naive Adult Patients with Chronic Chikungunya Arthritis.

Most studies on chronic chikungunya virus (CHIKV) arthritis include patients treated with disease-modifying antirheumatic drugs (DMARDs), likely altering the expression of clinical manifestations and outcome. Therefore, we sought to evaluate the clinical features and correlates in DMARD-naive patients with chronic CHIKV arthritis. We conducted a case-control study in adult patients with serologically confirmed CHIKV infection in Puerto Rico. Demographic features, clinical manifestations, comorbidities, disease activity (per Clinical Disease Activity Index [CDAI]), functional status (per Health Assessment Questionnaire Disability Index [HAQ-DI]), and pharmacologic treatment were ascertained. Patients with and without chronic CHIKV arthritis were compared. Furthermore, a sub-analysis was performed among patients with chronic CHIKV who presented with mild disease activity versus moderate-to-high disease activity at study visit. In total, 61 patients were studied; 33 patients had chronic arthritis and 28 had resolved arthritis. Patients with chronic arthritis had significantly more diabetes mellitus, chronic back pain, and fever, tiredness, and myalgias on the acute phase. The mean (SD) HAQ score was 0.95 (0.56), and 57.6% had moderate-to-high disease activity. Patients with moderate-to-high disease activity had higher scores in overall HAQ-DI and HAQ-DI categories (dressing and grooming, arising, hygiene, reaching, and activities) than in those with mild activity. In conclusion, in this group of DMARD-naive patients with chronic CHIKV arthritis, nearly 58% had moderate-to-high disease activity and had substantial functional disability. Diabetes mellitus, chronic back pain, and some manifestations on acute infection were associated with chronic CHIKV arthritis.

Spinal pigmented villonodular synovitis and tenosynovial giant cell tumor: A report of two cases and a comprehensive systematic review.

BACKGROUND AND OBJECTIVE: Pigmented villonodular synovitis (PVNS) is a lesion of uncertain etiology that involves the synovial membranes of joints or tendon sheaths, representing a diffuse and non-encapsulated form of the more common giant cell tumors of the synovium (GCTTS). PVNS was reclassified to denote a diffuse form of synovial giant cell tumor (TSGCT), while 'giant cell tumor of the tendon sheath (GCTTS)' was used for localized lesions. These pathologies rarely affect the axial skeleton. We provide an unprecedented and extensive systematic review of both lesions highlighting presentation, diagnostic considerations, treatment, prognosis, and outcomes, and we report a short case-series. METHOD: We describe two-cases and conduct a systematic review in accordance with PRISMA guidelines. RESULT: PVNS was identified in most of the cases reviewed (91.6 %), manifesting predominantly in the cervical spine (40 %). Patients commonly presented with neck pain (59 %), back pain (53 %), and lower back pain (81.2 %) for cervical, thoracic, and lumbar lesions, respectively. GTR occurred at rates of 94 %, 80 %, and 87.5 %. Recurrence was most common in the lumbar region (30.7 %). GCTTS cases (8%) manifested in the cervical and thoracic spine at the same frequency. We reported first case of GCTTS in the lumbosacral region. Both poses high rate of facet and epidural involvements. CONCLUSION: Spinal PVNS and GCTTS are rare. These lesions manifest most commonly as PVNS within the cervical spine. Both types have a high rate of facet and epidural involvement, while PVNS has the highest rate of recurrence within the lumbar spine. The clinical and radiological features of these lesions make them difficult to differentiate from others with similar histogenesis, necessitating tissue diagnosis. Proper management via GTR resolves the lesion, with low rates of recurrence.

Epidemiology of chronic back pain among adults and elderly from Southern Brazil: a cross-sectional study.

BACKGROUND: Chronic back pain (CBP) can negatively affect one's quality of life and health condition, posing significant social and economic burdens. OBJECTIVES: (1) To determine the prevalence of CBP and analyze associated factors in adult and elderly individuals in a municipality in southern Brazil; (2) to verify who sought medical attention or missed work because of back pain; and (3) to estimate the impact of CBP on selected health outcomes. METHODS: This was a population-based cross-sectional study conducted with individuals aged 18 years and older. CBP was defined as "pain for three consecutive months in the cervical, thoracic, or lumbar regions in the last year." Demographic, socioeconomic, behavioral, and physical and mental health information was collected. The impact of CBP was assessed by the etiological fraction method. RESULTS: The prevalence of CBP was 20.7% (95% CI: 18.3, 23.0) among the 1300 study participants. The factors associated with CBP were women, elderly, smokers, obesity, and sleeping fewer hours per night, as well as those with higher mental stress levels, history of fracture, arthritis/rheumatism, and work-related musculoskeletal disorder/repetitive strain injury. One-third of those with CBP missed work (31%) and 68% visited the physician over a 12-month period. All health outcomes analyzed (poor or very poor sleep quality, regular or poor health perception, worsened quality of life, depressive symptoms, perceived sadness) were significantly associated with CBP. CONCLUSION: One in five adults or elderly reported having CBP over the previous 12 months. This condition was associated with poorer health perception, poorer quality of life, and depressive symptoms.

Can Exercise Targeting Mid-Thoracic Spine Segmental Movement Reduce Back Pain and Improve Sensory Perception in Cross-Country Skiers?

OBJECTIVE: To assess the role of exercise targeting proper trunk stabilization and segmental spinal movement in back pain and sensory perception among cross-country skiers. DESIGN: Randomized, controlled trial with blinded outcome assessors. SETTING: University Hospital, Department of Rehabilitation and Sports Medicine. PARTICIPANTS: Twenty elite cross-country skiers aged 17 to 27 years. INTERVENTIONS: Ten cross-country skiers integrated 3 types of exercise targeting segmental motion in mid-thoracic spine into their routine training practice for 2 months. The 10 controls performed routine athletic training. MAIN OUTCOME MEASURES: The Young Spine Questionnaire to measure intensity and frequency of back pain was completed at the start and end of study. Tactile sensory perception using 10-g Semmes-Weinstein monofilament, thermic perception using TIP THERM device, graphesthesia assessed by a touch monitor pencil, 2-point discrimination assessed by a digital caliper, and vibration perception assessed by a 128-Hz tuning fork measured in mid-thoracic spine 5 times. RESULTS: No significant group differences in pain and sensory perception were identified at baseline. Over the 2-month study interval, repeated-measures analysis of variance revealed that the experimental group improved significantly relative to the control group on pain intensity (P = 0.005 for cervical, P = 0.004 for thoracic, and P = 0.014 for lumbar) and frequency of pain in the thoracic area only (P = 0.011). Improvements were also observed in the experimental relative to control group on graphesthesia (P < 0.001), vibration perception (P = 0.002), and 2-point discrimination (P < 0.001). CONCLUSIONS: Exercise targeting the mid-thoracic spine may decrease back pain and improve sensory perception in cross-country skiers. LEVEL OF EVIDENCE: Original research, level I.

Patient Expectations of Adult Spinal Deformity Correction Surgery.

BACKGROUND: There is a growing interest in examining preoperative expectations as a potential predictor of postoperative outcome. However, it has never been studied in the setting of adult spinal deformity (ASD). This study aims to characterize patient expectations before ASD surgery and examine the relationship between preoperative expectation and postoperative patient-reported outcomes (PROs). METHODS: Analysis of prospectively collected clinical and PRO data was performed on patients who underwent ASD surgery. Inclusion criteria were age >18 years, a diagnosis of ASD, >3 vertebral level instrumentation, and completed pre- and postoperative surveys. The preoperative expectation survey included expectations of surgical outcome, pain reduction, complications, and the duration of postoperative recovery. Relationships between patient expectations and PROs were assessed. RESULTS: Twenty-seven patients who underwent operative management of ASD met the inclusion criteria. In their preoperative survey, 66% of patients expected highly successful surgery, whereas 22% had a moderate expectation of complications. Patients anticipated an average 71% reduction in back pain (range 42%-100%) and 68% reduction in leg pain (range 0%-100%). Patients who met their expectations of leg pain reduction had significantly greater satisfaction scores than those who did not. There were moderate-to-strong positive correlations between preoperative expectation and observed improvement in back pain, leg pain, and mental health. CONCLUSIONS: While substantial variability in patient expectation exists for the surgical management of ASD, patients anticipated a positive outcome with a significant reduction in pain. Greater postoperative satisfaction was associated with patients who met the expected improvement in leg pain. Preoperative expectation was positively correlated with change in pain and mental health scores.

Surgical Intervention for Femoroacetabular Impingement Can Lead to Improvements in Both Hip and Back Function in Patients With Coexisting Chronic Back Pain at 1-Year Follow-Up.

PURPOSE: To determine whether patients with coexisting lumbar back pain experience back pain improvement after undergoing hip arthroscopy for femoroacetabular impingement (FAI). METHODS: An institutional review board-approved retrospective chart review compared patients undergoing hip arthroscopy for FAI with lumbar spine back pain to patients solely reporting hip pain. The modified Harris Hip Score (mHHS) and Nonarthritic Hip Score (NAHS) were recorded preoperatively and at 1-year follow up. The Oswestry Disability Index score, which quantifies disability from lower back pain, and visual analog scale were recorded from the hip-spine cohort alone. Statistical analysis was performed using paired sample t tests with P ≤ .05 considered significant. RESULTS: Sixty-eight patients who underwent hip arthroscopy between November 2016 and October 2018 were enrolled. Thirty-four patients with a mean age of 48.2 ± 14.0 years and body mass index of 26.6 ± 6.6 had a history of back pain and 34 patients were age- and sex-matched for the matched-control (MC) cohort. The MC cohort had lower mHHS and NAHS scores preoperatively. The MC cohort reported a larger increase in the mHHS (P = .01) and NAHS scores (P = .01) postoperatively. More patients in the MC cohort reached minimally clinically important difference with mHHS (P = .003) and NAHS (P = .06). Following surgery, the hip-spine cohort reported a lower Oswestry Disability Index score, indicating minimal disability (P = .01). CONCLUSIONS: Surgical intervention for FAI can lead to improvements in hip and back pain in patients with coexisting lumbar pathology. LEVEL OF EVIDENCE: III, retrospective comparative study.

Facet Joint Replacement: Intermediate- and Long-Term Outcome in a Large Case Series.

BACKGROUND: The long-term outcome of facet joint replacement (FJR) still is to be proven. METHODS: We present a prospective case series of 26 (male-to-female ratio of 1:1; mean age: 61 years) patients undergoing FJR with a follow-up of at least 1 year (range: 12-112; mean: 67 months). Visual analog scale (VAS) for back and leg pain, Oswestry Disability Index (ODI), and the 12-Item Short Form Health Survey (SF-12) were applied pre- and postoperatively (after 3, 6, and 12 months) as well as at the last follow-up (N = 24). Using X-rays of the lumbar spine (N = 20), the range of motion (ROM) and disk height in the indicator and adjacent levels were assessed. RESULTS: FJR was performed at L3/L4 (N = 7), L4/L5 (N = 17), and L5/S1 (N = 2). Mean VAS (mm) for back pain decreased from 71 to 18, mean VAS for right leg pain from 61 to 7, and from 51 to 3 for the left leg. Mean ODI dropped from 51 to 22% (for all p < 0.01). Eighty seven percent of patients were satisfied and pretreatment activities were completely regained in 78.3% of patients. Disk height at the indicator and adjacent levels and ROM at the indicator segment and the entire lumbar spine were preserved. No loosening of implants was observed. Explantation of FJR and subsequent fusion had to be performed in four cases (15.4%). CONCLUSIONS: In selected cases, long-term results of FJR show good outcome concerning pain, quality of life, preservation of lumbar spine motion, and protection of adjacent level.

Cross-sectional study of psychosocial and pain-related variables among patients with chronic pain during a time of social distancing imposed by the coronavirus disease 2019 pandemic.

ABSTRACT: The COVID-19 pandemic has had a tremendous impact, including on individuals with chronic pain. The social distancing policies necessary to slow the spread of SARS-CoV-2 have involved increased levels of social isolation. This cross-sectional survey study examined pain severity and interference among individuals with chronic pain during an early phase of social distancing mandates and identified characteristics of individuals who were most impacted. Approximately 4 to 8 weeks after social distancing mandates commenced in the state of Massachusetts, 150 patients with fibromyalgia, chronic spine, and postsurgical pain completed demographic, pain, social distancing, and validated psychosocial questionnaires. Patients self-reported an overall significant increase in pain severity and pain interference, compared with before social distancing, although both pain severity and interference were quite variable among individuals under conditions of social distancing. Several demographic, socioeconomic, and psychosocial factors were associated with greater pain severity and interference during social distancing. Multivariable linear regression demonstrated that female sex, nonwhite race, lower education, disability, fibromyalgia, and higher pain catastrophizing were independently associated with greater pain severity, while female sex and pain catastrophizing were independently associated greater pain interference. The findings suggest that individual differences among patients with chronic pain should be considered in the planning, development, and prioritization of interventions to improve pain care and to prevent worsening of symptoms during the continuing COVID-19 pandemic.

Back pain attitudes questionnaire: Cross-cultural adaptation to brazilian-portuguese and measurement properties.

BACKGROUND: The Back Pain Attitudes Questionnaire (Back-PAQ) was developed to evaluate attitudes and beliefs of the general public, people with back pain, and healthcare professionals about the spine. OBJECTIVES: To translate and cross-culturally adapt the Back-PAQ (34-item and 10-item versions) into Brazilian-Portuguese (Back-PAQ-Br) and test its measurement properties in a Brazilian sample. METHODS: The cross-cultural adaptation and testing of the measurement properties followed the recommendations of international guidelines. Members of the general public, people with back pain, and healthcare professionals, for a total of 139 individuals, took part in the assessment of internal consistency, construct validity, and ceiling and floor effects. The Hospital Anxiety and Depression Scale (HADS) and the Brazilian-Portuguese version of the Tampa Scale of Kinesiophobia (TSK) were used to evaluate construct validity. Test-retest reproducibility was determined on 77 participants. Retest was performed a minimum of 1 week and a maximum of 2 weeks from the original test. RESULTS: There was very high agreement between translators (88.2%). The Back-PAQ-Br showed excellent internal consistency (Cronbach's alpha 0.92) and excellent reproducibility (ICC 0.94; SEM 5.14 points on a 136 point scale), with a smallest detectable change (90% confidence level) of 11.93 points. There was strong correlation between Back-PAQ-Br and TSK (r = -0.72) and very weak correlation between Back-PAQ-Br and HADS (r = -0.23 for both depression and anxiety domains). No ceiling/floor effects were observed. CONCLUSION: The translation process and cross-cultural adaptation had very high agreement between translators. The Back-PAQ-Br has excellent measurement properties that are similar to the properties of the original version.

Patient journey following lumbar spinal fusion surgery (FuJourn): A multicentre exploration of the immediate post-operative period using qualitative patient diaries.

The aim of this study was to capture and understand the immediate recovery journey of patients following lumbar spinal fusion surgery and explore the interacting constructs that shape their journey. A qualitative study using Interpretive Phenomenological Analysis (IPA) approach. A purposive sample of 43 adult patients (≥16 years) undergoing ≤4 level instrumented fusion for back and/or leg pain of degenerative cause, were recruited pre-surgery from 4 UK spinal surgery centres. Patients completed a weekly diary expressed in their own words for the first 4 weeks following surgery to capture their life as lived. Diary content was based on previous research findings and recorded progress, recovery, motivation, symptoms, medications, healthcare appointments, rehabilitation, positive/negative thoughts, and significant moments; comparing to the previous week. To maximise completion and data quality, diaries could be completed in paper form, word document, as online survey or as audio recording. Strategies to enhance diary adherence included a weekly prompt. A framework analysis for individual diaries and then across participants (deductive and inductive components) captured emergent themes. Trustworthiness was enhanced by strategies including reflexivity, attention to negative cases and use of critical co-investigators. Twenty-eight participants (15 female; n = 18 (64.3%) aged 45-64) contributed weekly diaries (12 withdrew post-surgery, 3 did not follow through with surgery). Adherence with diaries was 89.8%. Participants provided diverse and vivid descriptions of recovery experiences. Three distinct recovery trajectories were identified: meaningful recovery (engagement in physical and functional activities to return to functionality/mobility); progressive recovery (small but meaningful improvement in physical ability with increasing confidence); and disruptive recovery (limited purpose for meaningful recovery). Important interacting constructs shaped participants' recovery including their pain experience and self-efficacy. This is the first account of immediate recovery trajectories from patients' perspectives. Recognition of a patient's trajectory may inform patient-centred recovery, follow-up and rehabilitation to improve patient outcomes.

The role of acupuncture in the treatment of chronic pain.

Acupuncture is a practice based on traditional Chinese medicine, in which needles are used to restore the body's internal balance. Recently, there has been growing interest in the use of acupuncture for various pain conditions. Acupuncture's efficacy in five pain conditions-low back pain (LBP), migraines, fibromyalgia, neck pain, and abdominal pain-was evaluated in this evidence-based, comprehensive review. Based on the most recent evidence, migraine and fibromyalgia are two conditions with the most favorable outcomes after acupuncture. At the same time, abdominal pain has the least evidence for the use of acupuncture. Acupuncture is efficacious for reducing pain in patients with LBP, and for short-term pain relief for those with neck pain. Further research needs to be done to evaluate acupuncture's efficacy in these conditions, especially for abdominal pain, as many of the current studies have a risk of bias due to lack of blinding and small sample size.
