ABSTRACT
The purpose of the study was to investigate the effects of passive recovery with self-selected time on affect, ratings of perceived exertion, and heart rate in self-selected interval exercises (SSIE). Fifteen older women (68.1 ± 3.8 years), weekly practitioners of functional activities participated in three SSIE with self-selected recovery time (SSRT) and one self-selected continuous exercise session, all at 24 min approximately. The SSIE had the following configurations: 1'/SSRT, 1.5'/SSRT, and 2'/SSRT. The results showed that at the beginning of stimulus heart rate in 1.5'/SSRT (107.9 ± 16.5) and 2'/SSRT (114.6 ± 17.1) were significantly greater (p < .05) compared with self-selected continuous exercise (102.8 ± 14.5). The ratings of perceived exertion in self-selected continuous exercise (2.4 ± 0.4; p < .05) were higher compared with SSIE in recovery. No significant differences were found in affect. The SSIE provided similar responses based on recoveries manipulations.

A coluna cervical é considerada como possível fonte de dor de cabeça, entretanto ainda existem algumascontrovérsias a respeito da fisiopatogênese, quadro clínico e tratamento. Objetivo: Proporum protocolo com abordagem multimodal para tratamento fisioterápico de pacientes com cefaleiacervicogênica e avaliar os efeitos deste protocolo em tais pacientes. Método: Trata-se deum estudo experimental não controlado, no qual 9 pacientes da Clínica Escola de Fisioterapia doUNIFESO (Teresópolis, RJ) com diagnóstico de cefaleia cervicogênica foram submetidos a 10 intervençõesfisioterapêuticas com técnicas de terapia manual. O protocolo experimental incluiu técnicasarticulares, miofasciais e de recrutamento muscular. Como ferramentas de mensuração foramutilizadas a escala funcional Neck Disabilty Index (NDI), a escala visual analógica de dor (EVA) e oregistro do padrão do quadro álgico. Resultados: Dos 9 pacientes selecionados, todos eram dogênero feminino, e possuíam média de idade de 43,3 anos (± 15,5). Observou-se diferença entreas médias da intensidade do quadro álgico (EVA) antes do tratamento (8,0 ± 1,3) e após (2,2 ± 0,9;p < 0,01). O índice de incapacidade cervical também mostrou melhora após intervenção de 63,9%(p < 0,01). Em relação à frequência das crises semanais observa-se uma diminuição de 70% apósa intervenção (p < 0,01). De maneira similar, houve redução do tempo de permanência das crisesantes (4 horas ± 1,5) e após (1 hora ± 0,5) (p < 0,01). Conclusão: A abordagem multimodal pormeio de técnicas de terapia manual foi benéfica na redução do quadro sintomático dos pacientese ainda proporcionou diminuição do grau de incapacidade da região cervical.
The cervical spine is considered a possible source of headaches, however there are still some controversiesregarding the pathophysiology, clinical presentation, and treatment. Objective: To proposea physical therapy treatment protocol with multimodal approach for cervicogenic headacheand evaluate the effects of manual therapy on such patients. Method: This was an uncontrolledexperimental study in which 9 patients from the UNIFESO Physical Therapy Clinic (Teresópolis, RJ)diagnosed with cervicogenic headache underwent 10 physiotherapy interventions with manualtherapy techniques. The experimental protocol included joint techniques, fascial release, andmuscle recruitment. The Neck Disability Index (NDI) and a visual analogic scale (VAS) were used asmeasurement tools and the pain pattern was recorded. Results: Of the nine selected patients, allwere female and had an average age of 43.3 years (± 15.5). Significant differences were observedbetween the average intensity of pain (VAS) before treatment (8.0 ± 1.3) and after (2.2 ± 0.9,p < 0.01). The NDI also showed improvement after intervention 63.9% (p < 0.01). Regarding crisesfrequency, a decrease of 70% was observed after the intervention (p < 0.01) and a reduction wasalso shown in the duration of such crises before (4 hours ± 1.5) and after treatment (1 hour ± 0.5;p < 0.01). Conclusion: A multimodal approach by manual therapy techniques was beneficial in thereduction of the patients? symptoms and it provided a decrease in cervical disability.

We investigated the influence of airway obstruction in the complexity of the airflow pattern in COPD and its use as a marker of disease activity. The sample entropy (SampEnV') and the variability (SDV') of the airflow pattern were measured in a group of 88 subjects with various levels of airway obstruction. Airway obstruction resulted in a reduction in the SampEnV' (p<0.0001) that was significantly correlated with spirometric indices of airway obstruction (R=0.50, p<0.001). The early adverse effects in mild airway obstruction were detected by the SampEnV' with an accuracy of 84%. SDV' increased with airway obstruction (p<0.002). We conclude that (1) the airflow patterns in COPD exhibit reduced complexity compared with healthy subjects; (2) this reduction in complexity is proportional to airway obstruction; and (3) the evaluation of SampEnV' may provide novel respiratory biomarkers suitable to facilitate the diagnosis of respiratory abnormalities in COPD.

Changes in thoracoabdominal motion are highly prevalent in patients with chronic respiratory diseases. Home care services that use telemedicine techniques and Internet-based monitoring have the potential to improve the management of these patients. However, there is no detailed description in the literature of a system for Internet-based monitoring of patients with disturbed thoracoabdominal motion. The purpose of this work was to describe the development of a new telemedicine instrument for Internet-based home monitoring of thoracoabdominal movement. The instrument directly measures changes in the thorax and abdomen circumferences and transfers data through a transmission control protocol∕Internet protocol connection. After the design details are described, the accuracy of the electronic and software processing units of the instrument is evaluated by using electronic signals simulating normal subjects and individuals with thoracoabdominal motion disorders. The results obtained during in vivo studies on normal subjects simulating thoracoabdominal motion disorders showed that this new system is able to detect a reduction in abdominal movement that is associated with abnormal thoracic breathing (p < 0.0001) and the reduction in thoracic movement during abnormal abdominal breathing (p < 0.005). Simulated asynchrony in thoracoabdominal motion was also adequately detected by the system (p < 0.0001). The experimental results obtained for patients with respiratory diseases were in close agreement with the expected values, providing evidence that this instrument can be a useful tool for the evaluation of thoracoabdominal motion. The Internet transmission tests showed that the acquisition and analysis of the thoracoabdominal motion signals can be performed remotely. The user can also receive medical recommendations. The proposed system can be used in a spectrum of telemedicine scenarios, which can reduce the costs of assistance offered to patients with respiratory diseases.

Introdução: O Flutter® VRP1 é um dispositivo que combina pressão positiva expiratória e oscilações de alta freqüência com objetivo de manter as vias aéreas pérvias. Apesar de sua utilização rotineira na prática da fisioterapia, seu efeito na mecânicarespiratória é escasso na literatura. O presente estudo investigou o efeito, a curto prazo, do uso deste dispositvo em indivíduos saudáveis e em pacientes portadores de Doença Pulmonar Obstrutiva Crônica (DPOC), asma e bronquiectasia. Metodologia: Os pacientes foram submetidos à utilização do Flutter® VRP1 por um período de 5 a 10 minutos. Para análise da mecânica respiratória, a técnica de oscilações forçadas (FOT) e a espirometria foram realizadas antes e imediatamente após o uso do dispositivo. Resultados: O uso do Flutter® VRP1 não resultou em alterações significativas nos parâmetros avaliados pela FOT nos grupos estudados. Considerando-se a espirometria, a única variável que apresentou diferença significativa (p<0,05) foi VEF1 (L) no grupo controle. Conclusão: Com o protocolo utilizado, nos grupos de indivíduos saudáveis e de portadores de DPOC, asma e bronquiectasia, o uso do Flutter® VRP1 não introduziu modificações, a curto prazo, na mecânica respiratória.
Introduction: The Flutter® VRP1 is a device that combines expiratory positive airway pressure with high frequency oscillations to keep airway clean. In spite of the widely clinical use, the effect analyze of this device in the respiratory mechanics of obstructive patients is little. The aim of the present study was to investigate the short-term effect of the use of the Flutter® VRP1 in healthy subjects and patients with Pulmonary Disease, Chronic Obstructive (COPD), asthma and bronchiectasis.Methodology: The patients were submitted to a protocol where the Flutter® VRP1 was used for a period of 5 to 10 minutes. Changes in pulmonary mechanics were analyzed by the forced oscillations technique (FOT) and spirometry, which were performed before and immediately after the use of the device. Results: The use of Flutter® VRP1 didnt result in significant alterations in the evaluated parameters of FOT in the studied groups. Considering spirometry, the only variable that presented significant difference (p <0.05) was VEF1 (L) in healthy group. Conclusion: With the used protocol, in the studied populationof healthy subjects and patients with COPD, asthma and bronchiectasis, the use of the Flutter® VRP1 do not introduced shortterm modifications in respiratory mechanics.
