Impact of moderate-severe persistent allergic rhinitis on thoraco-abdominal kinematics and respiratory muscle function.

Objective: To assess thoraco-abdominal kinematics, respiratory muscle strength and electromyographic activity of the diaphragm (EAdi) in moderate-severe allergic rhinitis (AR) patients. Methods: A cross-sectional study involving 40 individuals (20 in the AR group) and 20 in the control group [CG]) was conducted. Ventilatory pattern and chest wall volume distribution (optoelectronic plethysmography), respiratory muscle strength (manovacuometry and sniff nasal inspiratory pressure [SNIP]), and EAdi were assessed in both groups. Results: The AR patients had impaired thoraco-abdominal kinematics (reduced total chest wall volume) (p = 0.004), lower values of total respiratory cycle time (p = 0.014) and expiratory time (p = 0.006). They also presented an increase of percentage contribution of the abdominal rib cage (p = 0.475) and respiratory rate (p = 0.019). A positive correlation among pulmonary rib cage tidal volume and MIP (r = 0.544; p < 0.001), SNIP (r = 0.615; p < 0.001), and MEP (r = 0.604; p < 0.001) was observed. After adjusting for age, BMI and gender through multivariate analysis, the individuals with AR presented lower values ​​of MIP (ß = -24.341; p < 0.001), MEP (ß = -0.277; p < 0.001), SNIP (ß = -34.687; p < 0.001) and RMS (ß = -0.041; p = 0.017). Conclusions: The individuals with moderate-severe persistent AR had worse respiratory muscle strength, diaphragm activation and chest wall volume distribution with a higher abdominal contribution to tidal volume than the control group. These findings reinforce the notion that the upper and lower airways work in an integrated and synergistic manner.

Effects of electrical muscle stimulation early in the quadriceps and tibialis anterior muscle of critically ill patients.

BACKGROUND: Electrical muscle stimulation (EMS) is applied to critically ill patients in order to improve their muscle strength, thereby preventing hypotrophy and promoting functional recovery. OBJECTIVE: To assess the effects of early EMS on the range of movement of the ankle joint, and on thigh and leg circumference in critically ill patients. METHODS: This is a prospective randomized clinical trial comprising 11 patients undergoing mechanical ventilation. Before and after EMS the thigh and leg circumference in both lower limbs and the goniometry of the tibiotarsal joint were measured. The angle of 90° on the goniometer was taken as the standard neutral position (NP), with the arm fixed on the lateral malleolus of the ankle joint. Other measurements, namely dorsiflexion and plantar flexion, referred to as mobile arm, were taken from the NP. These recordings were obtained following an active contraction of the patients' muscles. RESULTS: Compared with the electrostimulated limb, a difference in dorsiflexion of the control limb was observed (96.2 ± 24.9 versus 119.9 ± 14.1°; p = 0.01). A girth of 10 cm of the leg was found in limb reduction when compared to the electrostimulated one (24.7 ± 3.1 versus 26.4 ± 4.0 cm; p = 0.03). CONCLUSIONS: EMS used at low current intensity and for a short duration failed to prevent muscle atrophy in critically ill patients. However, we did find a significant improvement in active dorsiflexion of the ankle joint suggesting that it could help to prevent against stance plantar flexion in these patients.

Influence of early mobilization on respiratory and peripheral muscle strength in critically ill patients. / Influência da mobilização precoce na força muscular periférica e respiratória em pacientes críticos.

OBJECTIVE: To evaluate the effects of an early mobilization protocol on respiratory and peripheral muscles in critically ill patients. METHODS: A randomized controlled clinical trial was conducted with 59 male and female patients on mechanical ventilation. The patients were divided into a conventional physical therapy group (control group, n=14) that received the sector's standard physical therapy program and an early mobilization group (n=14) that received a systematic early mobilization protocol. Peripheral muscle strength was assessed with the Medical Research Council score, and respiratory muscle strength (determined by the maximal inspiratory and expiratory pressures) was measured using a vacuum manometer with a unidirectional valve. Systematic early mobilization was performed on five levels. RESULTS: Significant increases were observed for values for maximal inspiratory pressure and the Medical Research Council score in the early mobilization group. However, no statistically significant improvement was observed for maximal expiratory pressure or MV duration (days), length of stay in the intensive care unit (days), and length of hospital stay (days). CONCLUSION: The early mobilization group showed gains in inspiratory and peripheral muscle strength.

Influência da mobilização precoce na força muscular periférica e respiratória em pacientes críticos / Influence of early mobilization on respiratory and peripheral muscle strength in critically ill patients

OBJETIVO: Avaliar os efeitos de um protocolo de mobilização precoce na musculatura periférica e respiratória de pacientes críticos. MÉTODOS: Ensaio clínico, controlado e randomizado realizado em 59 pacientes de ambos os gêneros, em ventilação mecânica. Os pacientes foram divididos em grupo fisioterapia convencional - grupo controle, n=14, que realizou a fisioterapia do setor, e grupo mobilização precoce, n=14, que recebeu um protocolo sistemático de mobilização precoce. A força muscular periférica foi avaliada por meio do Medical Research Council e a força muscular respiratória (dada por pressão inspiratória máxima e pressão expiratória máxima) foi mensurada pelo manovacuômetro com uma válvula unidirecional. A mobilização precoce sistemática foi realizada em cinco níveis. RESULTADOS: Para os valores de pressão inspiratória máxima e do Medical Research Council, foram encontrados ganhos significativos no grupo mobilização precoce. Entretanto, a pressão expiratória máxima e o tempo de ventilação mecânica (dias), tempo de internamento na unidade de terapia intensiva (dias), e tempo de internamento hospitalar (dias) não apresentaram significância estatística. CONCLUSÃO: Houve ganho da força muscular inspiratória e periférica para a população estudada quando submetida a um protocolo de mobilização precoce e sistematizado.

A eficácia dos recursos fisioterapêuticos no ganho da amplitude de abertura bucal em pacientes com disfunções craniomandibulares / The effectiveness of the physiotherapeutic resources in the gain of the amplitude of bucal opening in patients with craniomandibular dysfunctions

Introdução: A Articulação Temporomandibular (ATM) é um dos componentes do sistema estomatognático e vem sendo estudada por diversas áreas das ciências da saúde. Qualquer alteração em um dos constituintes articulares e musculares da ATM predispõe ao aparecimento das Disfunções Craniomandibulares (DCMs). A DCM caracteriza-se por diversos sinais e sintomas, como a limitação dos movimentos mandibulares, sendo classificada em musculares, articulares e musculoarticulares. A limitação dos movimentos da mandíbula pode estar associada à dor e aos desarranjos internos da ATM. Com isso, a fisioterapia é uma alternativa de tratamento das DCMs, melhorando os sinais e sintomas que as envolvem. Objetivo: Identificar a eficácia dos recursos fisioterapêuticos no ganho da amplitude de abertura bucal em pacientes com DCM, por meio de uma revisão de literatura. Metodologia: Foi realizado um levantamento bibliográfico nas seguintes bases de dados: PUBMED, SciELO, PEDro, HighWire Press e PERIÓDICOS CAPES no período de 1998 a 2008. Além disso, foram utilizados livros atualizados referentes ao tema abordado. Resultado: Dezessete artigos foram analisados, sendo cinco constatando a limitação de abertura bucal; os demais descreveram e sugeriram tratamentos para melhorar a amplitude de abertura bucal em pacientes com DCM. Conclusão: Foi observada melhora na amplitude de abertura da boca em pacientes com DCM, mediante os tratamentos propostos nos artigos revisados.

Introduction: The Temporomandibular joint (TMJ) is one of the components of the stomatognathic system and has been studied by several areas of health sciences. Any change in one of the constituents of the TMJ joint and muscle predisposes to the appearance of Craniomandibular disfunction (CMD). The CMD is characterized for several signs and symptoms, among them the limitation of the mandibular movements, being classified as muscle, to articulate and muscle to articulate. The limitation of movements of the jaw can be associated to the pain and to the internal disorders of the TMJ. With that, the physiotherapy is an alternative of treatment of the CMDs, improving the signs and symptoms that involve them. Objective: To identify the effectiveness of physiotherapy in the gain range of mouth opening in patients with DCM by means of a literature review. Methodology: A survey in the following bibliographic databases: PUBMED, SciELO, PEDro, and HighWire Press PERIODIC CAPES during 1998 to 2008. Furthermore, we used updated books on the subject addressed. Result: Seventeen articles were reviewed, with 5 noting the limitation of mouth opening, the other described and suggested treatments to improve the range of mouth opening in patients with DCM. Conclusion: There was improvement in range of mouth opening in patients with DCM, the treatments offered by the reviewed articles.
