Objective: To assess the effects of neural mobilisation on nerve function and nerve structure of patients with peripheral neuropathic pain.

Methods: A systematic review with meta-analysis was conducted. Medline, Embase, CINAHL, Cochrane Library, and World Health Organization International Clinical Trials Registry Platform were searched without restrictions.

Background: Clinical practice guidelines recommend spinal manipulation for patients with low back pain. However, the effects of spinal manipulation have contradictory findings compared to placebo intervention. Therefore, this study investigated the immediate effects of lumbar spinal manipulation on pressure pain threshold (PPT) and postural stability in people with chronic low back pain (cLBP).

Background: People with neuropathic-like symptoms had more unfavourable pain features than people with nociceptive. Moreover, deficient conditioned pain modulation is common in people with neuropathic-like symptoms. PainDETECT questionnaire have been used to assess the central sensitisation sign and symptoms.

Article Synopsis
  • The study aimed to identify factors that affect the effectiveness of pain inhibition using machine learning models to assess Conditioned Pain Modulation (CPM) in patients with musculoskeletal pain.
  • This exploratory research involved 311 outpatient participants, collecting data on their demographics, lifestyle, and clinical characteristics while employing a cold-pressure test to measure CPM efficacy.
  • The XGBoost model outperformed other algorithms, showing an accuracy of 81% and highlighting that pain duration, fatigue, physical activity, and number of painful areas significantly impacted CPM effectiveness, suggesting further research is needed for broader application.

Objective: This study aimed to compare the functional performance among participants with a neuropathic-like symptoms (NS) and central sensitization related signs and symptoms (CS), and their knee osteoarthritis (OA) counterparts.

Methods: A cross-sectional observational study was conducted with 125 participants with knee OA (94 females, mean age 63.1 ​± ​7.

Background: Low back pain (LBP) subgroup identification and management are a research priority. The clarification of subgroup differences could assist clinicians in clinical decisions contributing to a tailored treatment.

Objectives: To compare pain-related interference and pain-related psychosocial factors among subgroups of chronic low back pain (localised low back pain, peripheral neuropathic back pain, and widespread pain).

  • The study aimed to assess how well inertial sensors measure balance in patients with chronic low back pain versus healthy individuals.
  • A total of 78 participants were analyzed, with balance control evaluated using inertial sensors at the lumbar and sternum positions and compared against a force plate.
  • Results indicated that while correlations were observed between the inertial sensor readings and the force plate, they ranged from weak to moderate, especially in patients with chronic low back pain.

Background: Low back pain is one of the main public health concerns. Chronic low back pain (cLBP) reduces functional capacity and affects postural stability. Although health professionals widely use spinal manipulation, its immediate effect on painful sensitivity and postural stability is lacking.

Background: Musculoskeletal pain patients present similar pain characteristics regardless of the clinical diagnosis. PainDETECT questionnaire is useful for screening neuropathic-like symptoms in many musculoskeletal conditions. However, no previous studies compared pain phenotypes of patients with musculoskeletal pain using the painDETECT.

Advice to stay active is the primary management strategy for sciatica. Other conservative treatments such as neural management techniques may also contribute to sciatica recovery, but currently, the effects have not been robustly assessed. Thus, the aim of this study is to compare the effects of adding neural management to advice to stay active versus advice to stay active alone in improving pain intensity and functional limitation.

Article Synopsis
  • * It analyzed data from 529 workers, using various tests to assess the relationship between daily posture and low back pain, but overall, posture alone couldn't effectively differentiate those with and without pain.
  • * The only significant finding was that time spent walking somewhat indicated low back pain in the past year, though its accuracy was limited, and the posture data was unhelpful for recent episodes of pain.

The present study aimed to compare pain-related interference and pain-related distress in patients with musculoskeletal pain and differing levels of health literacy. A cross-sectional study was conducted among 243 patients with chronic musculoskeletal pain. Short Test of Functional Health Literacy in Adults classified the level of health literacy.

Background And Objectives: Neuropathic pain is common in the general population worldwide and Brazil. The painDETECT questionnaire is a notable instrument for screening on neuropathic pain. A Brazilian version of the painDETECT is necessary to broaden the possibilities of identification of neuropathic pain in the Brazilian population for the proper diagnosis and treatment.

Article Synopsis
  • The study analyzes the effectiveness of clinical indicators in diagnosing central sensitization (CS) in patients with chronic musculoskeletal pain, comparing these indicators to psychophysical tests.
  • One hundred patients were assessed using a combination of self-reported pain characteristics and physical examinations to identify CS-related signs and symptoms.
  • Results showed that clinical indicators were highly accurate in identifying CS, with a 75% accuracy rate, suggesting they are valuable tools for clinicians in managing musculoskeletal pain.

The black yeast-like fungus is known from strains that cause severe and eventually fatal disseminated infections in immunocompromised patients. Given the dramatic outcome of this clinical case, it is essential to understand the virulence potential of this species. The fungus is a member of the family , at some phylogenetic distance from the where most infectious fungi in the order are located.

Background: The assessment of painful areas through printed body charts is a simple way for clinicians to identify patients with widespread pain in primary care. However, there is a lack in the literature about a simple and automated method designed to analyze pain drawings in body charts in clinical practice.

Purpose: To test the inter- and intra-rater reliabilities and concurrent validity of software (PainMAP) for quantification of pain drawings in patients with low back pain.

Habitat fragmentation and a decrease in population size may lead to a loss in population genetic diversity. For the first time, the reduction in genetic diversity in the northernmost limit of natural occurence (southeastern Brazil) of Araucaria angustifolia in comparison with populations in the main area of the species continuous natural distribution (southern Brazil), was tested. The 673 AFLPs markers revealed a high level of genetic diversity for the species (Ht = 0.
