Objective: To compare the effect of conventional physical therapy and Pilates on function, restoration, and exercise ability in hospitalized chronic renal patients. Methods: A total of 56 inpatients were randomized into two groups: Conventional physical therapy and Pilates. The primary outcomes were functionality (Barthel Index), respiratory muscle strength (manovacuometry), and ability to exercise (step test) evaluated in the following periods: preintervention, after the 5th session, and after the 10th session or at discharge. Three months after randomization, the Barthel Index was applied over the phone. At the end of the 10 sessions or at discharge, the length of hospital stay was calculated and the level of satisfaction with physical therapy care was assessed (MedRisk). Linear mixed models were used for the primary outcomes and the Student's t-test was used for length of stay and satisfaction. Results: There was no significant between-group difference in functionality (MD -1.3; 95% CI -2.8 to 5.4), inspiratory and expiratory muscle strength (MD -1.3; 95% CI -7.3 to 4.5/MD -4.5; 95% CI -0.7 to 9.7, respectively), performance in the step test (MD -3.3; 95% CI -6.2 to 12.8), patient satisfaction with physical therapy care (MD -2.0; 95% CI -5.1 to 9.1), and length of stay (MD 4.5; 95% CI -15.9 to 6.8). Conclusion: Both interventions, conventional physical therapy and Pilates, showed improvements and there is no difference between them. Therefore both can be used in chronic renal patients.

OBJECTIVES: To measure the attitudes and beliefs of Brazilian physical therapists about chronic low back pain and to identify the sociodemographic characteristics that are more likely to influence these attitudes and beliefs. METHODS: We conducted a cross-sectional study with 100 Brazilian physical therapists who routinely work with chronic low back pain patients. The attitudes and beliefs were measured by the Pain Attitudes and Beliefs Scale for Physiotherapists (PABS.PT) and the Health Care Providers' Pain and Impairment Relationship Scale (HC-PAIRS). Multivariate linear regression models were built to identify sociodemographic characteristics that could be associated with physical therapists' attitudes and beliefs. RESULTS: Mean scores on the biomedical and biopsychosocial factors of PABS.PT were 27.06 (SD 7.19) and 24.34 (SD 6.31), respectively, and the mean score on HC-PAIRS was 45.45 (SD 10.45). The score on PABS.PTbiomedical was associated with gender and years of professional experience. No variable was associated with the score on PABS.PTbiopsychosocial. The score on HC-PAIRS was significantly associated with the number of back pain patients seen by the physical therapist each month. These results indicate that male and less experienced physical therapists tend to follow a biomedical approach to the treatment of chronic low back pain patients, and that the lower the professional experience the stronger the belief in the relationship between pain and disability. CONCLUSIONS: Brazilian physical therapists are uncertain of the factors involved in the development and maintenance of chronic low back pain and about the relationship between pain and disability in these patients. OBJETIVOS: Avaliar as atitudes e crenças de fisioterapeutas brasileiros sobre a dor lombar crônica e identificar características sociodemográficas que as influenciam. MÉTODOS: Este estudo transversal incluiu 100 fisioterapeutas brasileiros que atendem pacientes com dor lombar crônica em sua rotina clínica. As atitudes e crenças foram avaliadas pela Pain Attitudes and Beliefs Scale for Physiotherapists (PABS.PT) e Health Care Providers' Pain and Impairment Relationship Scale (HC-PAIRS). Foram construídos modelos de regressão linear multivariada para verificar as possíveis características sociodemográficas que poderiam estar associadas com as atitudes e crenças dos fisioterapeutas. RESULTADOS: Os escores médios dos fatores biomédico e comportamental da PABS.PT foram 27,06 (DP 7,19) e 24,34 (DP 6,31), respectivamente, e o escore médio da HC-PAIRS foi 45,45 (DP 10,45). O escore do PABS.PT Fator biomédico foi associado com gênero e anos de experiência profissional. Já o escore do PABS.PT Fator comportamental não foi associado com nenhuma variável. O escore do HC-PAIRS foi significativamente associado com o número de pacientes com dor lombar atendido por mês. Esses resultados indicam que fisioterapeutas experientes tendem a seguir uma abordagem biomédica no tratamento de pacientes com dor lombar crônica. Além disso, quanto menor a experiência profissional, mais forte é a crença na relação entre dor e incapacidade. CONCLUSÕES: Os fisioterapeutas brasileiros mostram-se incertos acerca dos fatores que envolvem o desenvolvimento e a manutenção da dor lombar crônica e também sobre a relação entre dor e incapacidade nesses pacientes. Isso põe em questão as atitudes e práticas em relação ao manejo dos pacientes com dor lombar crônica no Brasil.

- Abstract
Objective: The purpose of this study was to analyze the discriminative and predictive validity of the Brazilian Portuguese version of the Örebro Musculoskeletal Pain Screening Questionnaire Short-Form (ÖMPSQ-Short)., Methods: In this prospective longitudinal cohort study, the ÖMPSQ-Short was administered to 150 patients with acute, subacute, and chronic nonspecific low back pain. A 6-month follow-up was also completed to assess the predictive ability of the questionnaire for risk of pain, disability, and absence from work. The Roland-Morris disability questionnaire, pain numerical rating scale, and additional questions related to work and absence from work were also used., Results: The ÖMPSQ-Short cutoff point was determined by analyzing the receiver operating characteristic curve, sensitivity, and specificity, which yielded a value of 44 points for the Brazilian population. Analysis of the 2 × 2 contingency tables showed that the ÖMPSQ-Short correctly classified high-risk patients with pain. Predictive capacity was assessed by univariate linear regression analysis. The ÖMPSQ-Short was able to predict pain, disability, and absence from work in patients with acute pain and disability in patients with subacute pain, and disability and absence from work in patients with chronic pain, but with a small predictive capacity., Conclusion: The ÖMPSQ-Short cutoff demonstrated the ability to classify patients with low and high risk of involvement of psychosocial factors. However, due to its small predictive capacity, we suggest that the ÖMPSQ-Short should not be used to predict pain, disability, and absence from work over 6 months. However, we recommend using it as a guide to discuss the patient's clinical condition., (© 2022 by National University of Health Sciences.)

- Abstract
Background: Non-specific low back pain is a major health problem worldwide. Interventions based on exercises have been the most commonly used treatments for patients with this condition. Over the past few years, the Pilates method has been one of the most popular exercise programmes used in clinical practice., Objectives: To determine the effects of the Pilates method for patients with non-specific acute, subacute or chronic low back pain., Search Methods: We conducted the searches in CENTRAL, MEDLINE, EMBASE, CINAHL, PEDro and SPORTDiscus from the date of their inception to March 2014. We updated the search in June 2015 but these results have not yet been incorporated. We also searched the reference lists of eligible papers as well as six trial registry websites. We placed no limitations on language or date of publication., Selection Criteria: We only included randomised controlled trials that examined the effectiveness of Pilates intervention in adults with acute, subacute or chronic non-specific low back pain. The primary outcomes considered were pain, disability, global impression of recovery and quality of life., Data Collection and Analysis: Two independent raters performed the assessment of risk of bias in the included studies using the 'Risk of bias' assessment tool recommended by The Cochrane Collaboration. We also assessed clinical relevance by scoring five questions related to this domain as 'yes', 'no' or 'unclear'. We evaluated the overall quality of evidence using the GRADE approach and for effect sizes we used three levels: small (mean difference (MD) < 10% of the scale), medium (MD 10% to 20% of the scale) or large (MD > 20% of the scale). We converted outcome measures to a common 0 to 100 scale when different scales were used., Main Results: The search retrieved 126 trials; 10 fulfilled the inclusion criteria and we included them in the review (a total sample of 510 participants). Seven studies were considered to have low risk of bias, and three were considered as high risk of bias.A total of six trials compared Pilates to minimal intervention. There is low quality evidence that Pilates reduces pain compared with minimal intervention, with a medium effect size at short-term follow-up (less than three months after randomisation) (MD -14.05, 95% confidence interval (CI) -18.91 to -9.19). For intermediate-term follow-up (at least three months but less than 12 months after randomisation), two trials provided moderate quality evidence that Pilates reduces pain compared to minimal intervention, with a medium effect size (MD -10.54, 95% CI -18.46 to -2.62). Based on five trials, there is low quality evidence that Pilates improves disability compared with minimal intervention, with a small effect size at short-term follow-up (MD -7.95, 95% CI -13.23 to -2.67), and moderate quality evidence for an intermediate-term effect with a medium effect size (MD -11.17, 95% CI -18.41 to -3.92). Based on one trial and low quality evidence, a significant short-term effect with a small effect size was reported for function (MD 1.10, 95% CI 0.23 to 1.97) and global impression of recovery (MD 1.50, 95% CI 0.70 to 2.30), but not at intermediate-term follow-up for either outcome.Four trials compared Pilates to other exercises. For the outcome pain, we presented the results as a narrative synthesis due to the high level of heterogeneity. At short-term follow-up, based on low quality evidence, two trials demonstrated a significant effect in favour of Pilates and one trial did not find a significant difference. At intermediate-term follow-up, based on low quality evidence, one trial reported a significant effect in favour of Pilates, and one trial reported a non-significant difference for this comparison. For disability, there is moderate quality evidence that there is no significant difference between Pilates and other exercise either in the short term (MD -3.29, 95% CI -6.82 to 0.24) or in the intermediate term (MD -0.91, 95% CI -5.02 to 3.20) based on two studies for each comparison. Based on low quality evidence and one trial, there was no significant difference in function between Pilates and other exercises at short-term follow-up (MD 0.10, 95% CI -2.44 to 2.64), but there was a significant effect in favour of other exercises for intermediate-term function, with a small effect size (MD -3.60, 95% CI -7.00 to -0.20). Global impression of recovery was not assessed in this comparison and none of the trials included quality of life outcomes. Two trials assessed adverse events in this review, one did not find any adverse events, and another reported minor events., Authors' Conclusions: We did not find any high quality evidence for any of the treatment comparisons, outcomes or follow-up periods investigated. However, there is low to moderate quality evidence that Pilates is more effective than minimal intervention for pain and disability. When Pilates was compared with other exercises we found a small effect for function at intermediate-term follow-up. Thus, while there is some evidence for the effectiveness of Pilates for low back pain, there is no conclusive evidence that it is superior to other forms of exercises. The decision to use Pilates for low back pain may be based on the patient's or care provider's preferences, and costs.

- Abstract
Objective: There is little high-quality evidence on the efficacy of the Pilates-based exercises for the treatment of chronic nonspecific low back pain. Therefore, the objective of this paper is to present a study protocol to investigate the efficacy of adding Pilates-based exercises to a minimum intervention in patients with chronic non-specific low back pain., Methods: This randomized controlled trial will recruit 86 patients of both sexes, aged between 18 and 60 years, with chronic non-specific low back pain. The participants will be randomly allocated into 2 treatment groups: the Booklet Group, which will receive a booklet with postural orientations, and the Pilates Group, which will receive the same booklet in addition to a Pilates-based exercises program. The general and specific functional capacities of the patient, kinesiophobia, pain intensity, and the global perceived effect will be evaluated by a blinded assessor before randomization and at 6 weeks and 6 months after randomization. In addition, the expectations of the participants and their confidence in the treatment will be evaluated before the randomization and after the first treatment session, respectively., Conclusions: It is hoped that the results of this study will provide high-quality evidence on the usefulness of Pilates-based exercises in the treatment of chronic non-specific low back pain.

- Abstract
Unlabelled: Transcutaneous electrical nerve stimulation (TENS) is a noninvasive technique used for pain modulation. During application of TENS there is a fading of current sensation. Textbooks of electrophysical agents recommend that pulse amplitude should be constantly adjusted. This seems to be accepted clinically despite the fact that there is no direct experimental evidence. The aim of the current study was to investigate the hypoalgesic effect of adjusting TENS pulse amplitude on pressure pain thresholds (PPTs) in healthy humans. Fifty-six healthy TENS naïve participants were recruited and randomly assigned to 1 of 4 groups (n = 14 per group): control, placebo TENS, fixed pulse amplitude TENS, and adjusted pulse amplitude TENS. Both active and placebo TENS were applied to the dominant forearm. PPTs were recorded from 2 points on the dominant forearm and hand before, during, and after 40 minutes of TENS. TENS increased the PPTs on the forearm (P = .003) and hand (P = .003) in the group that received the adjusted pulse amplitude when compared to all other groups. The mean final pulse amplitude for the adjusted pulse amplitude TENS group was 35.51 mA when compared to the fixed pulse amplitude TENS group, which averaged 31.37 mA (P = .0318)., Perspective: These results suggest that it is important to adjust the pulse amplitude during TENS application to get the maximal analgesic effect. We propose that the fading of current sensation allows the use of higher pulse amplitudes, which would activate a greater number of and deeper tissue afferents to produce greater analgesia., (Copyright © 2011 American Pain Society.

- Abstract
Objective: The purpose of this study was to compare 2 different interventions, global postural reeducation (GPR) and static stretching exercises (SS), in the treatment of women with temporomandibular disorders (TMDs)., Methods: A total of 28 subjects with TMDs were randomized into 2 treatment groups: GPR, where therapy involved muscle global chain stretching, or SS, with conventional static stretching; but only 24 completed the study. Eight treatment sessions lasting 40 minutes each (weekly) were performed. Assessments were conducted at baseline, immediately after treatment end, and 2 months later. Measurements included pain intensity at the temporomandibular joint, headache, cervicalgia, teeth clenching, ear symptoms, restricted sleep, and difficulties for mastication, using a visual analogue scale. In addition, electromyographic activity and pain thresholds were measured at the masseter, anterior temporalis, sternocleidomastoid, and upper trapezius muscles. Two-way analysis of variance with Tukey post hoc test was used for between-group comparisons. Significance level was .05., Results: Comparing the pain assessments using the visual analogue scale, no significant differences were seen with the exception of severity of headaches at treatment end (GPR, 3.92 ± 2.98 cm; SS, 1.64 ± 1.66 cm; P < .024). In addition, no significant differences were seen for pain thresholds and for electromyographic activity (P > .05)., Conclusions: For the subjects in this study, both GPR and SS were similarly effective for the treatment of TMDs with muscular component. They equally reduced pain intensity, increased pain thresholds, and decreased electromyographic activity., (Copyright © 2010 National University of Health Sciences. Published by Mosby, Inc.

- Abstract
The myoelectric signal can be used to control many rehabilitation systems, for instance, prostheses and artificial neuromuscular electrical stimulation toward restoring movement to spinal cord injured subjects. These mobile systems are usually used in different environments and thus are being exposed to different noise levels with characteristics not completely known. In this article, three main techniques for noise reduction were evaluated: wavelet transform (WT), adaptive digital filters, and nonadaptive digital filters. The WT was used to reconstruct the signal with the components without noise information. Adaptive filters were designed using least mean square (LMS) and recursive least square (RLS) algorithms. Finite-impulse response (FIR) and infinite-impulse response (IIR) nonadaptive filters were used for comparison to both the adaptive filters and the signal reconstruction through the WT.
