title: Influence of static wrist orthosis on muscle activity and shoulder and elbow range of motion during a functional task: a biomechanical study

description: ABSTRACT Orthoses are therapeutic resources that are appropriate to protect and remedy deformities or to help in the performance of certain functions; however, its use may lead to proximal compensations in the shoulder. Thus, this study aims to evaluate the influence of dorsal static 30° extension orthoses on the shoulder and elbow biomechanics in 25 asymptomatic individuals during a functional task. The range of motion and muscle activation was collected by simultaneous and synchronized analysis during the Elui functional test related to feeding, under the conditions with and without the orthosis. In order to allow a comparison of the different subjects and muscles, the data were analyzed by EMG signal of each muscle and, for kinematic analysis, pre-defined marker coordinate systems were constructed. The captured signals were filtered and processed by custom software, and the t-test for paired samples, SPSS® software, p&lt;0.05, was used. We found significant increase in activation of the anterior deltoid and pectoralis major muscle in the reach phase and upper trapezius, anterior and posterior deltoid in the release phase with the orthosis. The kinematic analysis showed a significant increase in the range of motion of shoulder abduction movements, elbow flexion and pronation in the displacement phase and shoulder extension and elbow flexion movements in the release phase. Our findings suggest that the use of static wrist orthosis while performing a task can lead to compensations, with predominant activation of more proximal muscles of the upper limb.

title: Mental practice after physiotherapy maintains functional mobility of people with Parkinson’s disease

description: ABSTRACT The objective of the study was to evaluate the use of mental practice after motor physiotherapy to maintain the effects obtained in functional mobility of people with Parkinson’s disease (PD). This randomized, controlled, single-blind trial included 14 subjects in stages 1 to 3 (Hoehn & Yahr), aged 45-72 years. After the initial evaluation with Timed Up & Go (TUG), Dynamic Gait Index (DGI) and Falls Efficacy Scale International Brazil (FES-I Brazil), the subjects performed 15 sessions of motor physical therapy. They were reevaluated and randomly divided into Control Group (CG) and Mental Practice Group (MPG). After the allocation, MPG underwent 10 sessions of mental practice associated with home exercise guidelines. CG was instructed to perform the home exercises only. The groups were then reevaluated. It was verified that MPG continued presenting a reduction in mean TUG time in the second reevaluation (p=0.05). In the second DGI reevaluation, MPG maintained the same mean score of the first reevaluation and CG presented a decrease in the mean. There were no significant differences in the intergroup comparison of FES-I Brazil scores. Mental practice was able to maintain the gains in functional mobility of patients with PD obtained through physiotherapy.

title: Assessment of the toes flexor musculature in institutionalized and community-dwelling older adults: biomechanical aspects, mobility and falls

description: ABSTRACT Morphological, biomechanical and functional changes in the feet may increase the risk of fall in older adults. Institutionalized older adults have less mobility and greater risk of falling. The aim of this study is to check the relationship of the feet’s characteristics with the mobility and falls of institutionalized or active community-dwelling older adults. A total of 15 institutionalized and 15 community-dwelling older adults participated in this study. They were assessed considering the incidence of falls and through the Timed Up and Go Test; presence of hallux valgus; and strength peak of the muscles of the hallux and toes measured by a pressure platform. The variance analysis was used to compare the groups. As a result, the community-dwelling older adults showed greater muscle strength of the toe flexor muscles than institutionalized older adults (p&lt;0.05) and better functional mobility. We observed the risk of fall in institutionalized older adults. Hallux valgus of mild degree was the most common deformity. The Pearson’s correlation coefficient showed no correlation between the analyzed variables and incidence of falls. We concluded that the strength of toe flexor muscles is greater in community-dwelling older adults, as well as the functional mobility, when compared with institutionalized older adults.

title: Functional assessment of the pelvic floor muscles by electromyography: is there a normalization in data analysis? A systematic review

description: ABSTRACT This study aims to evaluate the method of analysis of electromyographic data considering the functional assessment of pelvic floor muscles (PFM). We have included in our search strategy the following databases: Medline, PubMed, Cochrane Central Register of Controlled Trials and Cochrane Database of Systematic Reviews, PEDro, and IBECS, considering articles published in the last ten years (2004-2014). The identified articles were independently examined by two evaluators, according to these inclusion criteria: (1) population: female adults; (2) PFM assessment by electromyography (EMG) with vaginal/anal probe; and (3) description of how electromyographic data analysis is performed. The Newcastle-Ottawa Scale (NOS) was used to assess the risk of bias. We identified 508 articles, of which 23 were included in the review. The data showed differences between the collection protocols, and a significant number of studies did not normalize the electromyographic data. Physiotherapists are among the clinicians who most frequently use EMG to evaluate the function and dysfunction of the neuromuscular system. Although some previous studies have provided an overview to guide the evaluator in the assessment, few succeeding studies followed their recommendations.

title: Effect of interferential current in patients with fibromyalgia: a systematic review

description: ABSTRACT High-intensity and widespread muscle pain is the main complaint of patients with fibromyalgia. Interferential current is a treatment often used in pain relief; however, its effects on these patients are unclear. The objective of this review was to analyze the effects of interferential current therapy on the treatment of patients with fibromyalgia in previously published scientific articles. We searched the following databases: Central, CINAHL, Lilacs, PEDro, Medline (PubMed), SciELO, Science Direct, Scopus and Web of Science on November 2016. We included only controlled clinical trials and had no restrictions for language and date of publication. We used the Cochrane Collaboration’s tool to assess the risk of bias of the articles. We found a total of 415 articles, however, only four of them were selected for analysis. Three of these studies were excluded because they were not controlled clinical trials. Thus, only one study was analyzed for this review. According to the study the combination of ultrasound and interferential current improved pain relief and the sleep quality of patients with fibromyalgia. However, the study presented a high risk of bias, being impossible to verify the isolated effect of the interferential current in those patients. Randomized controlled studies on the use of interferential current in patients with fibromyalgia are lacking on literature. The results of this review evidence the importance of developing future studies with adequate methodological design and using only interferential current therapy to improve the use of this therapy for these patients in this clinical setting.

title: Effects of cathode and anode of the direct current on changes in palmar grip strength: assessment through a dynamometry

description: ABSTRACT This study objective is to investigate the polar effects of the direct current on muscular strength, evaluated by the manual dynamometer. The values of muscle strength, in kilograms, were compared before and after the procedure in the 3 groups (Anode, Cathode and Control). The project is a controlled randomized clinical trial, which was performed at the Laboratory of Physiotherapy of the University Andrés Bello (Physioterpy Carrer) with 150 healthy voluntary participants. The intervention consisted on the application of a direct current session with intensity of 2mA for 12 minutes, with an electrode of 48cm2 (dose of 24mA×min and current density of 0.04mA/cm2). The difference between the groups was in the stimulus with the cathode or the anode, and the application of the current was performed after the initial dynamometric evaluation. The main measured variable was the difference of maximum force of palmar grip (Kg), which was obtained through the difference between the best value of maximum pre-intervention force and the best value of maximum post-intervention force. The results indicate that there were no statistically significant changes in the intervention groups (p value=0.88) when comparing the maximum strength differences (FMdif). However, a slight improvement in strength was observed when comparing the groups only considering men from the cathode group (p value=0.94), and a slight decrease when comparing only women from the anode group (p value=0.91). It was concluded that, apparently, the direct current would not generate greater changes in the force of manual grasp after an intervention session on the forearm. Nevertheless, there are positive variations of strength in men from the cathode group, and negative ones in women from the anode group when analyzed independently, although these modifications are not statistically significant.

title: Mobility of right and left hemidiaphragms in healthy individuals and in individuals with chronic obstructive pulmonary disease

description: ABSTRACT To evaluate the diaphragm muscle is important for verifying its possible changes or malfunctions. There are several ways to evaluate the diaphragmatic mobility, but only a few compare the mobility of the right hemidiaphragm with the left one. The aim of this study was to evaluate whether there are differences between the mobility of right and left hemidiaphragms in healthy individuals and individuals with chronic obstructive pulmonary disease (COPD), as well as to evaluate the diaphragmatic mobility between men and women, and between healthy and COPD patients. We evaluated 40 healthy individuals and 40 individuals with clinical diagnosis of COPD. Anthropometric and cardiopulmonary parameters were used. The diaphragmatic mobility was evaluated by radiography. Data were statistically analyzed and processed with descriptive analysis (mean and standard deviation) and inferential analysis. To compare the mobilities of the right and left hemidiaphragms, the paired t-test was used. The significance level adopted for statistical treatment was 5% (p&lt;0.05). There was no difference of the diaphragmatic mobility for both left and right sides in healthy individuals (p=0.45) and individuals with COPD (p=0.77). Also, no differences were found when groups were separated according to sex. An important difference was found comparing both diaphragmatic mobilities of the right and left sides between healthy and COPD individuals (p&lt;0.001). We concluded that mobility of left and right hemidiaphragms in healthy and COPD individuals is the same. There is no difference for mobility between men and women. Diaphragmatic mobility is reduced in COPD patients.

title: Comparison of respiratory muscle strength, quality of life and functional capacity among adolescents with cystic fibrosis with different bacteriological profiles

description: ABSTRACT We compared the respiratory muscle strength, quality of life and functional capacity in adolescents with cystic fibrosis with different bacteriological profiles. This is a cross-sectional study of descriptive character on adolescents with cystic fibrosis assessed in the Reference Center for Cystic Fibrosis of the Octávio Mangabeira Specialized Hospital (HEOM) from January to March 2016, characterizing a sample for convenience. Muscle strength evaluation with the manovacuometer was performed, as well as analysis of the quality of life through the application of quality-of-life questionnaire with validation for patients with cystic fibrosis (CFQ), analysis of the functional capacity, after the six-minute walk test, and bacteriological profile, through results of microbiological tests. We evaluated 30 individuals with cystic fibrosis, in which, for Staphylococcus aureus, respiratory muscle strength (75.6±19.6*), quality of life CFQ (59.3±3.4), and functional capacity (427.8±64.6*) were verified. For Pseudomonas aeruginosa, the respiratory muscle strength (61.4±19.1*), quality of life CFQ (47.9±4.2) and the functional capacity (382.0±78.0*) were analyzed. We concluded that both bacteriological profiles impair lung function, especially the bacterium Pseudomonas aeruginosa, which has a tendency to respiratory muscle weakness, especially for women (Mip&lt;60cmH2O) and low functional capacity.
