ABSTRACT
Aim: To investigate the neuromuscular fatigue and recovery after an intermittent isometric handgrip exercise (IIHE) executed until failure with different blood flow restriction (BFR) conditions (free flow, partial and total vascular restriction). Methods: Thirteen healthy men carried out an IIHE at 45% of maximum voluntary isometric force (MVIF) until failure with total restriction (TR), partial restriction (PR) or free flow (FF). The rate of force development (RFD) was extracted from the MIVF over the time intervals of 0-30, 0-50, 0-100, and 0-200ms and normalized by MVIF [relative RFD (RFDr)]. Results: The RFDr decreased significantly (p<0.01) after the IIHE in all BFR conditions and time intervals studied, remaining lower for five minutes. The medians of the RFDr in FF condition were significantly lower (p=0.01) at 30ms (1.56 %MVIF·s-1) and 50ms (1.70 %MVIF·s-1) when compared to TR at 30ms (2.34 %MVIF·s-1) and 50ms (2.63 %MVIF·s-1) in minute 1 post failure. Conclusions: These results show that, regardless of the blood flow restriction level, there is no RFD recovery five minutes after an exhaustive IIHE. When the task was executed with FF, the reduction of the RFD was greater when compared with the TR condition.(AU)

Introduction: Access to rehabilitation in stroke patients is critical, considering the physical and psychological disabilities and generates social impact involved. Purpose: Evaluate the effectiveness of neurorehabilitation in collective mode, compared to the individual mode, in improving social support among patients with stroke, after application of the constraint induced of movement therapy. Methods: A randomized controlled trial of 36 patients who had a stroke were divided into two intervention groups. The independent variable was the implementation of collective or individual therapy for 3 hours for 10 consecutive days and the dependent variable was social perception evaluated by the Medical Outcomes Study-Social Support Survey (MOS-SSS) at baseline (pre-test) and end (post-test). Results: After controlling the pre-test scores, analysis of covariance revealed significant differences in favor of the collective mode in all post-test social support dimensions. Conclusions: Compared with the individual mode, the collective mode significantly improves several aspects of the patient’s perceived social support, thus providing evidence of its clinical and practical effectiveness.

OBJETIVO: Investigar o uso da contenção física em hospital psiquiátrico no Rio de Janeiro. MÉTODOS: Um inquérito foi conduzido em agosto de 2009. As informações - sexo, idade, diagnóstico, ocorrência e duração de contenção física - foram coletadas no prontuário. RESULTADO: A amostra consistiu em 66 pacientes, dos quais 59 por cento eram mulheres, com idade média de 44 anos. Durante o período estudado, 24 por cento dos pacientes foram contidos no leito pelo menos uma vez, mas não é prática corrente o registro detalhado do procedimento. Não ocorreram eventos adversos importantes. Não houve associação entre o uso de contenção e variáveis sociodemográficas e clínicas. CONCLUSÕES: A prática de contenção física parece consistente nas emergências psiquiátricas do Rio de Janeiro: esse mesmo percentual foi observado em estudos conduzidos em três hospitais em outros momentos, 2001 e 2004, e situa-se em uma faixa intermediária em relação aos resultados observados em outros países. Não existem estudos randomizados para se fazer uma avaliação objetiva dos benefícios e riscos dessa prática, mas a segurança e a eficácia dessa intervenção deveriam ser objeto do mesmo escrutínio científico normalmente destinado aos outros tratamentos.
OBJECTIVE: To evaluate the use of restraints in a large psychiatric hospital in Rio de Janeiro city, Brazil. METHODS:A survey was carried on in August 2009. Data on sex, age, diagnostic, use and duration of restraints were collected from patients' notes. RESULT: Sample consisted on 66 patients, 59 percent women, with mean age of 44 years. During the study 24 percent of the patients were restrained at least once, but registering details of the procedure was not usual. There were no important adverse events. No associations were observed between restraints and sociodemographic and clinic variables. CONCLUSIONS: The use of restraints is a consistent practice in Rio de Janeiro's psychiatric hospitals: the same proportion was observed in three hospitals in distinct periods, 2001 and 2004, and this finding is in an intermediate position in relation to other studies results. There are no randomized trials to properly evaluate the benefits and risks of this practice, but the efficacy and safety of this intervention should be subject to the same scientific scrutiny as other treatments.

Cerebral palsy is a non progressive disorder and the most common movement problem in children. Many children with cerebral palsy are of hemiplegic type. One of the important problems of this children is unilateral upper limb dysfunction, that not using the affected side causes forgetfulness and more problems on this side. In this study, effectiveness of Constraint-Induced Therapy [CIT] and the maintainance of this technique on spasticity and performance of upper extremity in hemiplegic cerebral palsy children 6 to 12 years old have been investigated. In this pretest - posttest quasi experimental study, 20 cerebral palsy hemiplegic children 6 to 12 years old [15 boys and 5 girls] with 8.7 years mean age were selected. Interventions were performed about 8 weeks and patients were followed for 4 weeks. Spasticity on the affected side in wrist and elbow were tested by Modified Ashworth Scale and upper extremity function by the Box and Block test. The data were analyzed with the Wilcoxon and paired t- tests. Constraint-Induced Therapy in the affected limb decreases significantly the spasticity of wrist [p = 0.00] and elbow [p = 0.005] and significantly increases performance score [p = 0.00], and the recovery significantly maintained one month after the interventions. Constraint-Induced Therapy of affected upper extremity could possibly decrease limb spasticity and increase function with two mechanisms: Fierstly, The reduction of not using the plegic side and secondly, neuroplasticity in CNS. This improvement may remain viable in the affected limb

CONTEXT: Writer's cramp is a kind of focal hand dystonia that appears when individuals are writing. Since pharmacological treatment has not shown the desired therapeutic response, a study on immobilization of the damaged musculature was performed on two individuals with writer's cramp, using splints with the objective of reducing the handwriting abnormalities. CASE REPORT: Two patients presenting writer's cramp who had previously undergone different therapies, including botulinum toxin, without an adequate response, participated in a body awareness program, followed by immobilization of the hand musculature damaged by dystonia, by means of splints, with handwriting training. At the end of the procedure, objective and subjective improvements in the motor pattern of writing could be observed. The immobilization of the dystonic musculature of the hand by means of splints and the motor training of handwriting helped to improve and consequently to reduce the dystonic component observed in the writer's cramp.
CONTEXTO: A câimbra do escrivão é um tipo de distonia focal da mão que aparece quando a pessoa escreve. Como o tratamento farmacológico não tem mostrado a resposta terapêutica almejada, um estudo sobre a imobilização da musculatura comprometida foi feito em dois indivíduos com câimbra do escrivão, utilizando órteses com o objetivo de reduzir as alterações da escrita. RELATO DE CASO: Dois pacientes apresentando câimbra do escrivão que haviam sido submetidos previamente a terapêuticas, inclusive toxina botulínica, sem resposta adequada, participaram de um programa de consciência corporal, seguido de imobilização por órteses da musculatura da mão comprometida pela distonia, com treinamento da escrita. Ao término, evidenciaram melhora objetiva e subjetiva no padrão motor da escrita. A imobilização por órteses da musculatura distônica da mão e o treinamento motor da escrita favorecem a melhora e, consequentemente, a redução do componente distônico observado na câimbra do escrivão.

PURPOSE: To evaluate the craniocervical isolation collar, for use in rabbits, with regard to the following aspects: effectiveness of the craniocervical attachment for up to 120 hours; ease of handling; freedom of the animal to move about and ingest food; and the physical integrity of the animal during and after use of the device. METHODS: Starting from an Elizabethan collar, a craniocervical collar was prepared for use in rabbits with the following modifications: a wide cut in the device in the shape of a half-moon, coinciding with the animal's mouth; inner division of the device into two compartments to individually isolate and immobilize the ears; multiple perforations in the upper compartment for better ventilation; adaptation of the cervical-thoracic band to attach the collar to the cervical region, keeping the fasteners on the animal's back. The device was used on 18 male New Zealand rabbits for up to 120 consecutive hours. RESULTS: The device was effective in the craniocervical isolation and separation of ears in rabbits without interfering with the animals' respiration, ability to swallow food, or causing physical trauma, while allowing the animals to move about freely and rest comfortably. Attaching and removing the device was easy and quick and it remained in place for up to 120 hours without the need to reposition it. CONCLUSION: The modified craniocervical isolation collar made it possible to conduct the experiment with isolation of the rabbits' ears, ease of handling, and without causing limitations in relation to the animals' ability to eat and move about freely.
OBJETIVO: Avaliar um colar de isolamento crânio-cervical, para uso em coelhos, quanto aos seguintes aspectos: eficácia da fixação crânio-cervical em até 120 h; facilidade de manuseio; liberdade do animal para deambular e ingerir alimentos; integridade física do animal durante e depois do uso do dispositivo. MÉTODOS: A partir do colar elizabetano confeccionou-se um colar de isolamento crânio-cervical para uso em coelhos, com as seguintes modificações: amplo corte no aparelho, em forma de meia lua, coincidindo com a boca do animal; divisão interna do dispositivo em dois compartimentos, para isolar e imobilizar as orelhas, individualmente; perfurações múltiplas no compartimento superior para melhor ventilação; adaptação de correia cérvico-torácica, para fixar o colar na região cervical, mantendo-se as presilhas de fechamento no dorso do animal. O dispositivo foi utilizado em 18 coelhos machos da raça Nova Zelândia, por período de até 120 horas consecutivas. RESULTADOS: O aparelho foi eficaz no isolamento crânio-cervical e das orelhas de coelhos, não interferiu nas funções respiratórias do animal, na deglutição de alimentos e não causou trauma físico, permitindo a livre deambulação e conforto no repouso. Foi de fácil e rápido manuseio na colocação e retirada, permanecendo no local sem necessidade de reposicionamento por até 120 horas. CONCLUSÃO: O colar de isolamento crânio-cervical modificado possibilitou a realização do experimento com isolamento das orelhas dos coelhos, com facilidade no manuseio, sem causar limitações ao animal em relação à ingestão de alimentos e deambulação.

OBJECTIVE: Chronic stress has been shown to cause oxidative damage in the central nervous system. Although stress-induced impairments in learning and memory have been studied extensively, very few studies have investigated possible ways to prevent their ill effects. The present work was designed to study the protective effects of ascorbic acid in memory loss induced by chronic restraint stress. METHODS: Adult male Wistar rats were designated into the following groups: (i) Normal control, (ii) Ascorbic acid treatment, (iii) Vehicle control, (iv) Restraint stress, (v) Restraint stress + vehicle, and (vi) Restraint stress + ascorbic acid treatment. At the end of 21 days, animals of all groups were subjected to memory tests using Morris water maze and passive avoidance apparatus. Then, the results obtained were compared between the experimental groups. RESULTS: Rats exposed to restraint stress alone and those pretreated with vehicle solution before restrained stress showed deficits in learning and impaired memory retention in the memory tests when compared to animals in other experimental groups. Animals pretreated with ascorbic acid before restraining showed significant improvement in memory retention in the same memory tests. CONCLUSIONS: Results of this study suggest the possibility of using ascorbic acid as a dietary supplement to prevent stress-induced memory impairments.

El manejo inicial de pacientes agresivos es frecuente en la práctica clínica, sin embargo, tanto el diagnóstico como el tratamiento iniciales tienden a ser imprecisos. La restricción física es una práctica muy usada por el personal de la salud, pero poco se sabe sobre su metodología, indicaciones, contraindicaciones y efectos adversos. Con el interés de aportar pautas, al personal de salud, encargado de la atención médica primaria de los pacientes agresivos en Colombia; realizamos una búsqueda en la literatura de los últimos cinco años en MEDLINE, HINARI, PROQUEST y OVID mediante combinación de la siguientes palabras clave: restraint, physical, aggression; emergency services, psychiatric; tranquilizing agents, con especial atención a los artículos de revisión y metaanálisis. Se seleccionaron 28 de 202 artículos de mayor relevancia para su aplicación en nuestro medio. Las indicaciones más importantes de restricción son: el riesgo de hetero o auto agresividad y el daño a la planta física. Existen claras contraindicaciones e implicaciones éticas, médicas y legales de los procedimientos de restricción que se deben acatar juiciosamente para realizar una adecuada práctica clínica. El adecuado uso de la restricción física del paciente agitado o agresivo, en unidades de atención primaria, es vital para su adecuado tratamiento y pronóstico. Es muy importante identificar la patología médica general subyacente

To compare the effects of ketamine and tiletaminezolazepam (TZ) drugs widely used for the chemical restraint and immobilization of primates, on various physiological parameters and blood gas values in cynomolgus monkeys (Macaca facicularis). Rectal temperature, heart rate, respiration rate and blood gas analysis were measured before treatment and at 1, 10, 20, 30, 40, 50 and 60 min after administration. Additionally, in both groups, induction and maintenance times were compared. Heart rate, respiration rate, rectal temperature, pH and pCO2 were not significant different in the two groups. However, pO2 in the ketamine-treated group was significantly lower at 30 and 40 min than in the TZ-treated group. The induction time was short in both groups, and the maintenance time was longer in the TZ-treated group (67.8+/-6.5 min) than in the ketamine-treated group (42.3+/-6.7 min). However, decreased rectal temperatures must be watched and prevented following TZ administration to cynomolgus monkeys. It was considered that ketamine may be useful for short duration anesthesia including handling, physical examination, blood sampling and TZ may be useful for prolonged anesthesia including minor surgery and other surgical procedure.

Introdução: Ainda que a contenção física em psiquiatria seja um ato cotidiano, não foram encontrados estudos sobre este tema realizados no país. Objetivos: O presente estudo tem como objetivos: 1) caracterizar em que circunstâncias ocorre a contenção física de pacientes na Unidade Psiquiátrica no HC/Unicamp; 2) caracterizar o grupo dos pacientes contidos e diferenciáðlo de um grupo de pacientes nãoðcontidos. Material e método: O estudo realizado foi retrospectivo, com base na análise de prontuários e de um banco de dados informatizado na qual constam escalas como BPRS, GAS e MMSE. a amostra utilizada foi de cem internações selecionadas aleatoriamente de um total de 344 internações consecutivas ocorridas entre 1996 e 1997. Resultados: O grupo dos pacientes contidos durante o período de hospitalização não apresentou diferenças significativas quanto a idade, escolaridade ou número de internações anteriores em relação aos pacientes nãoðsubmetidos a este procedimento. Pacientes do sexo feminino, com menor tempo de uso de psicofármacos e internados pela última vez havia mais tempo foram mais freqüentemente contidos. Pacientes negros e mulatos foram significativamente entre os dois grupos. Discussão e conclusão: Há uma possibilidade de variáveis étnicas e sociodemográficas, como cor do paciente, interferirem nas condutas médicas. Procedimentos como contenção física devem ser protocoladas e mais estudados em nosso meio

The study was carried out in three hospitals in three different countries: Riyadh Mental Health Hospital [Saudi Arabia], Psychological Medicine Hospital [Kuwait] and El-Nabawy El-Mohandes Hospital [Alexandria, Egypt]. The total sample comprised 257 nurses. Data were collected through the use of a questionnaire developed by the investigators and guided by Heyman's [1987] instrument covering the following main broad areas: reason for restraint, nurses' feelings when restraining patients and patients' feelings during restraint, time needed for restraint, the effect of restraint on patients, and possible changes in the use of restraint. Results revealed that uncontrolled behavior and aggression towards other persons, oneself and objects are the most common behavior leading to restraint in nurses' opinion. Also, restraint helps patient to calm down and behave better after its removal. The majority of nurses attributed more negative feelings to patients while restrained, as well as feeling guilty about restaining patients. Time needed for restraint as well as possible changes in the use of restraint varied among nurses
