Aim/objective: The aim is to critically analyse and discuss the current literature and determine the effectiveness of rehabilitation for patients after surgical repair of rotator cuff tears for range of motion (ROM), pain, functional status and retear rates; in addition, an update of new literature is included., Design: Overview of systematic reviews., Data Sources: A search was performed with no restrictions to date of publication and language in the following databases: EBSCO, AMED, CINAHL, SPORTDiscus, EMBASE, Cochrane, LILACS, MEDLINE, PEDro, Scielo, SCOPUS and Web of Knowledge. The PRISMA guideline was followed to develop this review and the R-AMSTAR tool was used for critical appraisal of included reviews., Eligibility Criteria: Only systematic reviews and randomised controlled trials (RCTs) comparing the effectiveness of early with conservative rehabilitation, after surgical repair of the rotator cuff, were included. Moreover, the studies should report ROM, pain, functional status and/or retears rates before and after 3-24 months of the surgery., Results: 10 systematic reviews and 11 RCTs were included for the final analysis. Conflicting results and conclusions were presented by the systematic reviews, the use of primary studies varied; also the methodological quality of the reviews was diverse. This updated review, with new meta-analysis, showed no difference for function, pain, ROM or retears ratio between early and conservative rehabilitation., Summary/conclusions: Early mobilisation may be beneficial, particularly for small and medium tears; however, more studies with higher quality are required, especially for patients with large tears who have been given less attention., Competing Interests: Competing interests: None declared., (Published by the BMJ Publishing Group Limited.

Introduction: The aims of this study were to determine the motor unit behavior of the erector spinae muscles and to assess whether differences exist between the dominant/nondominant sides of the back muscles., Methods: Nine healthy women, aged 21.7 years (SD = 0.7), performed a back extension test. Surface electromyographic decomposition data were collected from both sides of the erector spinae and decomposed into individual motor unit action potential trains. The mean firing rate for each motor unit was calculated, and a regression analysis was performed against the corresponding recruitment thresholds., Results: The mean firing rate ranged from 15.9 to 23.9 pps and 15.8 to 20.6 pps on the dominant and nondominant sides, respectively. However, the early motor unit potentials of the nondominant lumbar erector spinae muscles were recruited at a lower firing rate., Conclusions: This technique may further our understanding of individuals with back pain and other underlying neuromuscular diseases.

Soccer matches consist of a variety of different activities, including repeated sprints. Time to attain velocity (TTAV), load range (LR) and the torque-angle-velocity relationship (TAV 3D ) represent an important measurement of muscle performance, however there are few related studies. The aim of this study was to compare these outcomes between soccer players of different age category. 17 professional (PRO) and 17 under-17 (U17) soccer players were assessed for concentric knee flexion/extension at 60, 120 and 300°/s. For the extensor muscles, differences were found in favor of the U17 group for TTAV and LR outcomes at 120°/s, however, the PRO group maintained higher torques in both movement directions in comparison to the U17 in TAV 3D evaluation. These results suggest that muscle performance of the PRO group is more efficient than the U17 group., (© Georg Thieme Verlag KG Stuttgart · New York.)

Introduction: Physical conditioning consists of a variety of health-related attributes and Pilates exercises are described as a form of this conditioning. The objective of this systematic review was to determine the effect of the Pilates method on health and ability outcome of the physical conditioning of healthy individuals., Evidence Acquisition: The search was performed in the following databases: Medline, Cinahl, Embase, Lilacs, Scielo, Web of Science, PEDro, Cochrane Controlled Trials Register Library, Scopus, Science Direct and Google Scholar. (1950-2014). Included studies were randomized controlled trials (RCTs) that assessed the effects of the Pilates method on healthy subjects., Evidence Synthesis: Nine RCTs met the inclusion criteria. Pilates improved abdominal muscular endurance when compared with no exercises (mean difference [MD]=9.53%; 95% CI: 2.41, 16.43; P=0.009), however, there was no difference in flexibility (MD=4.97; 95% CI: -0.53, 10.47; P=0.08). Some positive effects (up to 6 months) of the Pilates practice were found in some RCTs' results as follows: Improvement of dynamic balance, quality of life and back muscle flexibility., Conclusions: The results indicate the Pilates exercises performed on the mat or apparatus 2 to 3 times a week, for 5 to 12 weeks, improves abdominal muscular endurance (on average, 10 more abdominals curls in 1-minute sit-up test) for both genders, when compared to no exercises.

Low back pain (LBP) is one of the most common causes of disability, and the Pilates method has been associated with improvements in symptoms. The purpose of this study was to assess the effectiveness of the Pilates method, when compared to general exercises, on pain and functionality after eight weeks (16 sessions, 2×/week) and a follow-up of three months, in subjects with non-specific chronic low back pain (NSCLBP). A randomised controlled trial composed of 22 subjects was proposed. Subjects were allocated into two groups: the Pilates group (PG) (n = 11) and the general exercise group (GEG) (n = 11). The PG protocol was based on the Pilates method and the GEG performed exercises to manage NSCLBP. There were no differences between the groups. When analysed over time, the GEG demonstrated improvements in functionality between baseline and the end of treatment (P = .02; Cohen'sd¯ = 0.34) and baseline and follow-up (P = .04; Cohen'sd¯ = 0.31). There were no differences between the Pilates and general exercises with regard to pain and functionality in NSCLBP subjects but general exercises were better than Pilates for increasing functionality and flexibility., (Copyright © 2014 Elsevier Ltd.

This study compared abdominal electromyographic (EMG) activity during the performance of Pilates' exercises. 16 females participated in the study. EMG signals of the rectus abdominis (RA) and external oblique (EO) were recorded during Longspine performed on the mat, Cadillac, and Reformer and the Teaser performed on the mat, Cadillac, and Combo-chair. Values were normalized by the EMG peak of a dynamic task and divided in concentric and eccentric phases. Longspine performed on the mat increased EO activity in the concentric phase more than on the Reformer and the Cadillac (Mean Difference (MD)=12.2%; 95% Confidence Interval (CI) [3.36; 21.04]; p=.04). Differences in the eccentric phase of the RA favored the mat compared to the Reformer (MD=5.20%; 95% CI [-0.55; 10.95]; p=.02). Significant differences in eccentric contraction of the RA were found for teaser exercise performed on the mat versus Cadillac (MD=1.1%; 95% CI [-4.13; 6.33]; p=.04) and the mat versus the Combo-chair (MD=6.3%; 95% CI [1.31; 11.29]; p=.005). Higher concentric activation values for the EO were found when the teaser exercise was performed on the Cadillac. Exercises performed on the mat required greater rectus abdominis activation., (Copyright © 2014 Elsevier Ltd. All rights reserved.)

[Purpose] The aim of the present study was described the kinematic characteristics of gait in stroke patients with two different arteries involved. [Subjects and Methods] Two patients who had suffered a basilar (A) or middle (B) cerebral artery ischemic stroke were compared with a control (C). Seventeen inertial sensors were used with acquisition rate of 120 Hz. The participants walked 3 times on a 10 meter walkway. From the raw data, the three gait cycles from the middle of each trial were chosen and analyzed. [Results] During the stance phase, patients A and B had a lower hip angle at initial contact and maximum flexion angle during load response than the control. Patient A and the control subject had similar knee angle values at initial contact, and patient B presented a flexed position in the initial phase of the gait cycle. The maximum flexion angles during loading response were also higher for patient B. The sagittal plane excursion for the ankle joint was lower for patient B in comparison with the other subjects. [Conclusion] Differences during walking between patients who had stroke in different arteries may be related to an alternative compensatory strategy. Patient A and the control subject had similar gait cycle curves at all joints, while patient B showed a rigid synergic pattern.

Objective: To assess the effectiveness of aquatic physical therapy in the treatment of fibromyalgia., Data Sources: The search strategy was undertaken using the following databases, from 1950 to December 2012: MEDLINE, EMBASE, CINAHL, LILACS, SCIELO, WEB OF SCIENCE, SCOPUS, SPORTDiscus, Cochrane Library Controlled Trials Register, Cochrane Disease Group Trials Register, PEDro and DARE., Review Methods: The studies were separated into groups: Group I - aquatic physical therapy × no treatment, Group II - aquatic physical therapy × land-based exercises and Group III - aquatic physical therapy × other treatments., Results: Seventy-two abstracts were found, 27 of which met the inclusion criteria. For the functional ability (Fibromyalgia Impact Questionnaire), three studies were considered with a treatment time of more than 20 weeks and a mean difference (MD) of -1.35 [-2.04; -0.67], P = 0.0001 was found in favour of the aquatic physical therapy group versus no treatment. The same results were identified for stiffness and the 6-minute walk test where two studies were pooled with an MD of -1.58 [-2.58; -0.58], P = 0.002 and 43.5 (metres) [3.8; 83.2], P = 0.03, respectively., Conclusion: Three meta-analyses showed statistically significant results in favour of the aquatic physical therapy (Fibromyalgia Impact Questionnaire, stiffness and the 6-minute walk test) during a period of longer than 20 weeks. Due to the low methodological rigor, the results were insufficient to demonstrate statistical and clinical differences in most of the outcomes.

Study Design: Systematic review with meta-analysis., Objectives: To evaluate the effectiveness of postoperative physical therapy treatment for patients who have undergone arthroscopic partial meniscectomy., Background: There is no consensus on which treatment is best for patients post meniscectomy., Methods: A search for articles published from 1950 to March 2013 was conducted in the MEDLINE, Embase, CINAHL, LILACS, SciELO, IBECS, Scopus, Web of Science, PEDro, Academic Search Premier, and Cochrane Central Register of Controlled Trials databases. The key words were physiotherapy, physical therapy modalities, exercise therapy, rehabilitation, knee, placebo, groups, tibial meniscus, meniscus, arthroscopy, meniscectomy, partial meniscectomy, randomized controlled trial, controlled clinical trial, randomized, systematic review, and meta-analysis., Results: Eighteen randomized controlled trials were included in the review, 6 of which were included in the meta-analysis. Outpatient physical therapy plus a home exercise program, compared to a home program alone, improved function compared to a home program alone (mean difference, 10.3; 95% confidence interval: 1.3, 19.3; P = .02) and knee flexion range of motion (mean difference, 9.1; 95% confidence interval: 3.7, 14.5; P = .0009). Inpatient physical therapy alone compared to inpatient plus outpatient physical therapy reduced the likelihood of effusion (odds ratio = 0.25; 95% confidence interval: 0.10, 0.61; P = .003)., Conclusion: Physical therapy associated with home exercises seems to be effective in improving patient-reported knee function and range of motion in patients post-arthroscopic meniscectomy, although the included randomized controlled trials were classified from moderate to high risk of bias and should be interpreted with caution., Level of Evidence: Therapy, level 1a-.

Background: There is a lack of questionnaires in Brazilian Portuguese to evaluate patient-reported lower limb function., Objective: To translate, cross-culturally adapt to the Brazilian population, and evaluate the psychometric properties of the Lower Extremity Functional Scale (LEFS)., Method: The LEFS was translated by two independent assessors and back-translated to English. Then, the LEFS-Brazil was tested on 20 patients who answered the questionnaire in the cross-cultural adaptation phase. For the evaluation of the psychometric properties, 100 patients answered the questionnaire. The reliability was tested by two independent assessors. The Medical Outcomes Study 36-item from Health Survey (SF-36) was used as the criterion method for construct validity. The sensitivity to change was tested for four consecutive weeks., Results: The internal consistency was α = 0.96. The intra-observer reliability was CCI (intraclass correlation coefficient) = 0.96 and CCI interobserver = 0.98; the Bland and Altman mean difference (d) intra-observer = -1.52 and d interobserver = 0.46. The correlation between the LEFS and SF-36 in the first week was the following: physical function r=0.82, physical role r=0.57, emotional role r=0.43 and mental health r=0.33. The LEFS was responsive when comparing the mean of the first week to the second, third and fourth weeks and comparing the second to the fourth week. The cut-off point was 11, and the area under the receiving operator curve was 0.96 95% CI [0.88;0.99], with sensitivity = 0.96, 1-specificity = 0 and standard error = 0.02., Conclusion: The LEFS-Brazil is reliable, valid and responsive.
