Evaluation of the Neuropathic Component of Chronic Low Back Pain Assessment of neuropathic pain in chronic low back syndromes is important. However, there is currently no gold standard for its diagnosis. The aim of this observational cross-sectional study was to assess the neuropathic component of pain in various chronic low back pain syndromes using a range of diagnostic tests.Included in this study were 63 patients with chronic axial low back pain (ALBP), 48 patients with chronic radicular (...) syndromes (CRS) comprising 23 with discogenic compression (CDRS) and 25 with lumbar spinal stenosis (LSS), and 74 controls. PainDETECT questionnaire (PDQ), quantitative sensory testing (QST), and skin biopsy with evaluation of intraepidermal nerve fiber density (IENFD) were used to assess the neuropathic pain component.Positive PDQ (≥19) was obtained more frequently in patients with CDRS and LSS (26.1% and 12.0%, respectively) compared with patients with ALBP (1.6%, P<0.001). The proportion of patients
Safety of oral methylnaltrexone for opioid-induced constipation in patients with chronic noncancer pain Oral methylnaltrexone was shown to be effective in treating opioid-induced constipation (OIC) in patients with chronic noncancer pain in a Phase III randomized controlled trial. This report provides a detailed safety analysis from that study.Adults (n=803) with chronic noncancer pain for ≥2 months and confirmed OIC while receiving opioid doses ≥50 mg morphine equivalent per day for ≥14 days (...) generally small and similar across treatment groups. Rescue-laxative use was more common with placebo than methylnaltrexone 450 mg (6.20% vs 4.27% of study days, P=0.024). Changes in opioid dose, OOWS and SOWS scores, and pain-intensity scores during treatment were minimal.Oral methylnaltrexone had a safety profile comparable with placebo in the treatment of OIC in patients with chronic noncancer pain, with no evidence of cardiac toxicity or opioid withdrawal.

The secondary outcome
Patient-delivered tDCS on chronic neuropathic pain in prior responders to TMS (a randomized controlled pilot study) Successful response to repetitive transcranial magnetic stimulation (rTMS) of the motor cortex requires continued maintenance treatments. Transcranial Direct Current Stimulation (tDCS) may provide a more convenient alternative.This pilot study aimed to examine the feasibility of a randomized, double-blind, double-crossover pilot study for patients to self-administer tDCS motor (...) cortex stimulation for 20 minutes/day over five consecutive days. Primary outcomes were as follows: usability of patient-administered tDCS, compliance with device, recruitment, and retention rates. Secondary outcomes were as follows: effect on overall pain levels and quality of life via Short Form-36 anxiety and depression via Hospital Anxiety and Depression Scale, and Mini-Mental State scores.A total of 24 subjects with neuropathic pain, who had previously experienced rTMS motor cortex stimulation
Efficacy of Internet-Delivered Mindfulness for Improving Depression in Caregivers of People With Spinal Cord Injuries and Chronic Neuropathic Pain: A Randomized Controlled Feasibility Trial To explore the feasibility and efficacy of web-based mindfulness training for carers of people with spinal cord injury (SCI).Randomized controlled feasibility study with 3-month follow-up.Community setting.Spouses or family caregivers (N=55) of people with SCI and chronic neuropathic pain were recruited via (...) the direct care team and advertisements. Participants were older than 18 years (no upper age limit), with Internet access for the duration of the study. Participants were randomly allocated to an 8-week online mindfulness training intervention (n=28), or to receive 8 weeks of psychoeducational materials on SCI and chronicpain (n=27).An established web-based, mindfulness training course was delivered over 8 weeks. Participants completed 10 minutes of mindfulness practices, twice per day, 6 days per week
Effects of spinal manipulative therapy biomechanical parameters on clinical and biomechanical outcomes of participants with chronic thoracic pain: a randomized controlled experimental trial Spinal manipulative therapy (SMT) includes biomechanical parameters that vary between clinicians, but for which the influence on the therapy clinical effects is unknown. This parallel-randomized controlled trial aimed to investigate the effect of SMT biomechanical parameters on the outcomes of participants (...) with chronic thoracic pain (CTP) following three treatment sessions (follow-up at one week).Adults reporting CTP (pain within the evaluated region [T6 to T8] for ≥3 months) were asked to participate in a four-session trial. At the first session, participants were randomly assigned to one of three experimental groups (different SMT doses) or the control group (no SMT). During the first three sessions, one SMT was executed at T7 for the experimental groups, while a 5-min rest was provided to the control

Is graded exercise beneficial in improving function, mobility and quality of life in adult patients with chronic musculoskeletal pain? Getting Evidence into Clinical Practice: Musculoskeletal Research Facilitation Group (CAT Group) Date: June 2017 CAT Lead: Laura Freeman / Treena Larkin (South Staffs Group) Date CAT completed: June 2017 Date to be reviewed June 2022 Specific Question: Is graded exercise beneficial in improving function, mobility, quality of life in adult patients with chronic (...) musculoskeletal pain? Clinical bottom line There is limited evidence of poor quality to answer this question with confidence. The studies that were identified were of poor quality and therefore results should be viewed with caution. Why is this important? Exercise is generally considered an important part of chronicpain management. Much evidence exists empirically to support the benefits of activity / exercise in the management of chronicpain. However many patients struggle to exercise / increase activity

The effect of lumbosacral orthosis on the thickness of deep trunk muscles using ultrasound imaging: A randomized controlled trial in patients with chronic low back pain. This study was conducted to evaluate the changes occurring in the thickness of deep trunk muscles, measured using ultrasound imaging, after four weeks of lumbosacral orthosis (LSO) use in conjunction with routine physical therapy.This parallel-group, randomized, controlled trial was conducted on 44 patients with nonspecific (...) chronic low back pain (CLBP), randomly allocated to the experimental and control groups. Both groups received eight sessions of physical therapy twice per week for four weeks. The experimental group wore non-extensible LSO in addition to undergoing routine physical therapy. The thickness of the transversus abdominis (TrA), obliquus internus (IO) and lumbar multifidus (LM) was measured by ultrasound before and after the four-week intervention.The deep trunk muscles differed in thickness in various test
Effects of an anteroposterior mobilization of the glenohumeral joint in overhead athletes with chronic shoulder pain: A randomized controlled trial. Passive oscillatory mobilizations are often employed by physiotherapists to reduce shoulder pain and increase function. However, there is little data about the neurophysiological effects of these mobilizations.To investigate the initial effects of an anteroposterior (AP) shoulder joint mobilization on measures of pain and function in overhead (...) athletes with chronic shoulder pain.Double-blind, controlled, within-subject, repeated-measures design.Thirty-one overhead athletes with chronic shoulder pain participated. The effects of a 9-min, AP mobilization of the glenohumeral joint were compared with manual contact and no-contact interventions. Self-reported pain, pressure pain threshold (PPT), range of movement (ROM), muscle strength, and disability were measured immediately before and after each intervention.No significant differences were
Identifying and Engaging Neuronal Oscillations by Transcranial Alternating Current Stimulation in Patients With Chronic Low Back Pain: A Randomized, Crossover, Double-Blind, Sham-Controlled Pilot Study Chronicpain is associated with maladaptive reorganization of the central nervous system. Recent studies have suggested that disorganization of large-scale electrical brain activity patterns, such as neuronal network oscillations in the thalamocortical system, plays a key role (...) in the pathophysiology of chronicpain. Yet, little is known about whether and how such network pathologies can be targeted with noninvasive brain stimulation as a nonpharmacological treatment option. We hypothesized that alpha oscillations, a prominent thalamocortical activity pattern in the human brain, are impaired in chronicpain and can be modulated with transcranial alternating current stimulation (tACS). We performed a randomized, crossover, double-blind, sham-controlled study in patients with chronic low
