Trauma em idosos atendidos pelo serviço pré-hospitalar móvel

O The aim of this study was to characterize the occurrence of trauma in the elderly population served by the mobile pre-hospital service, in Natal, Rio Grande do Norte. This is a descriptive, transversal and quantitative approach and whose population consisted of 2,080 trauma victims. The sample, of systematic random type, consisted of 400 elderly people, aged from 60 years old, assisted by the Office of Mobile Emergency in Natal / RN, between January 2011 and December 2012. Data collection began after consent and assent of the institution of a Research Ethics Committee under No. 309 505. It was proceeded to documentary retrospective analysis of records of this service through a form of self-development, validated by expert judges considered reliable (α> 0.75) and valid (CVI = 0.97) in their clarity and relevance. Data were tabulated by the Statistical Package for Social Sciences, version 20.0. The results show that older victims have an average age of 74.19 years old, with a prevalence of female involvement by chronic diseases, especially hypertension, average usage of 2.2 routine medications with vital signs within normal limits. The trauma prevailed during the daytime, in the residence of the victims, north of the city and on weekends. Among the mechanisms of trauma were falls, traffic accidents and physical aggression, whose most common type was brain-cerebral trauma and the main consequences were suture wounds and closed fractures. Basic Support Units were as more driven to pre-hospital care (87.8%) and the main destination place consisted of a referral hospital for emergency of the state (57.5%). Among the most commonly performed procedures by nursing staff immobilization with rigid board and neck collar and the peripheral venipuncture, and the main component used for volume replacement to saline were highlighted. There was a significant relationship between the deaths and the mechanism of injury, mechanism of injury and procedures, except medication administration procedures carried out, except immobilization and unit for service. It is highlighted the prevalence of trauma in the elderly, poor follow-up Pre-Hospital Trauma Life Support protocol and the paucity of records and nursing procedures performed. There is need for a protocol of care specific to elderly trauma victims and education strategies for the prevention of such events

Avaliação da qualidade da água do Rio Piranhas-Açu/RN utilizando a comunidade de macroinvertebrados bentônicos

The biomonitoring technique for water quality in water bodies has been incorporated increasingly in management of the natural resources, using mainly indices of its aquatic community characteristics. In Brazil the first efforts to use this technique was restricted to the South and the Midwest region of this country. Located in the northeast region, this study was conducted at Rio Grande do Norte state and had as main objective the assessment of water quality in the Piranhas-Açu river using benthic macroinvertebrates community as biological indicators. Thus, were applied two biotic indices, the BMWP (Biological Monitoring Working Party score system) and the IBF (Family Biotic Index). According the requirements of these indices, two periods of sampling were determined as basic methodology, in dry seasons of 2006 and 2007. The sampling sites were around the municipalities of Açu, Ipanguaçu, Alto do Rodrigues and Pendências. Physical-chemical measurements; a protocol of rapid assessment of diversity of habitats, and determination of the degree of tolerance of each taxon to organic pollution were also performed. The most abundant organisms found in the river were tolerant with the prevalence of Chironomidae (Diptera) and Melanoides tuberculata. This results, together with those ones got in indices application, showed a considerable organic pollution in the four sample places and the reaches were classified as modified to impacted. According to the used indices, this study suggest that this river have significant alteration in the biotic community and water quality on the organic pollution, and this fact, occurs in the reach of the river further downstream, where were expected a good water quality. Considering these results, measures aiming the conservation of this water body are needed regarding as it is inserted into a fragile ecosystem with dry season phenomenon, and the water of this river has extremely importance for the local economy

Prevalência e fatores associados à sintomatologia dolorosa e a qualidade de vida de odontólogos da cidade de Teresina-PI

Objective: Identify the factors associated to the painful symptomatology and the quality of life and in dentists in the city of Teresina-PI. Brazil. Methods It was accomplished a cross-sectional study with 175 dentists registered with the Regional Council of Dentistry-PI from March to May, 2007. For characterization of the dentists we used a multidimensional questionnaire containing sociodemographic (age, sex) and professional information (time of service, journey to work). The evaluation of the presence of pain was performed by the Protocol of Painful Symptoms of McGILL. The WHOQOL-Bref was used to assess quality of life through physical, psychological, social and environmental domains. Results / Conclusions The painful symptomatology was reported in 69,7% of individuals, being observed in 77.3% of women and 60.3% of men. Body regions where pain was prevalent was the regions of neck (69,2%) lower back (69,7%). The dentists had high levels of self-perception of quality of life satisfaction and health. 96,0% of the individuals reported quality of life as very good, and only 16.6% reported dissatisfied with health. The Physical and Environmental domains showed values higher than the psychological and social domains. The painful symptomatology of studied dentists is associated with female sex (RP=1.28; IC95% 1.04-1.58; p<0.01). A multivariate analysis by logistic regression was performed and only the painful symptoms (OR = 2.51, IC95% 1,21-5,21) remained associated with the quality of life of these professionals when adjusted for other variables studied

Representações sociais sobre o acidente de trabalho em saúde

The aim of the present study was to identify the representational elements of workrelated accidents in the health field, as well as investigate their most frequent occurrences at a university hospital, seeking to understand the cognitive, affective and social elements subjacent to the work process involved in health. The analysis focused on 470 middle and senior support staff of this hospital, based on the theoretical-methodological support of the Social Representations Theory. A combination of the following instruments was used for data collection: a free wordassociation test, a questionnaire, an interview and a field journal. Evoc 2000 software was used to identify representational structure. Chi-square and Mann-Whitney tests, at a significance level of 5%, were performed to verify the association between the independent variables and the occurrence of work accidents. In addition, thematic content analysis and lexicographic analysis by ALCESTE software program were used to understand textual content. It was observed that social representations of work-related accidents in the health area are centered in the contamination category, while the categories of prevention and professional unpreparedness are found peripherally. There was a significant association between the existence of multiple employment, the use of personal protective equipment (PPI) during work, job satisfaction and the occurrence of work accidents. The conclusions indicate that perforating-cutting occupational accidents predominated in the hospital and that the representations of the subjects intertwined, with a traditional discourse of work accidents strongly present in Occupational Health. It is therefore suggested that certain subjective aspects related to culture, in terms of controlling work accidents, such as: management, process, organization and the increasing precariousness

Fisioterapia e sociedade: ações do Sistema Único de Saúde no Rio Grande do Norte

The work has objective to present actions of Physiotherapy, developed by SUS in the State of Rio Grande do Norte; discuss under the humanization point of view such actions of health; discuss the importance of physioterapy to the Norte-Riograndense, or maybe its role in the perpetuation of actions of health centered in the binomial cause/efect. The study was done in the State of Rio Grande do Norte. The data were obtained through public sources gathered in the health secretrary ship of this State. The collected data talks about physiotherapy sections developed by SUS in several areas of the State; such data was collected and analysed after the aproval of Ethic and Resarch Committee of Federal University of Rio Grande do Norte. Concerning the physiotherapy, along with the State Health Secretaryship of the State fo Rio Grande do Norte, there were only records of attending based on cure/rehabillitation, not being observed during the curse of study, any record or action of prevention, promotion and protection towards health. It s possible to notice that there is a highligth to the interventions focusing on the treatment of illness of rheumatic origin and general complaints related to the vertebral column. Such research evidenced that the Physiotherapy in the SUS in the State priorizes the individualized attending centered in the carteziano health/illness model, where the developde actions are turned to the curative and rehabilliting attention, with role fo some or no highligth in the primary attention

As práticas educativas na saúde da família: uma cartografia simbólica

This qualitative research aimed to understand the educational activities carried out in Family Health Units, of the municipality of Mossoró-RN. It was used symbolic cartography to organize and present data from reality. It started on the approach of Health Education and knowledge transformation practice, aiming at the development of autonomy and responsibility of individuals and healthcare, publicized by the appreciation of the interpersonal relations area established in services, such as educational emancipator practices contexts. Individual and collective interviews were realized, conducted with health professionals and users of ESF, about themes, activities, membership, the difficulties, the potential and the design of health education that permeate everyday Family Health Strategy. From what was apprehended, thematic maps were done with the analysis of educational practices of professionals belonging to the Family‟s Health. Links are built with the wires of conceptions of education reflected on themes and activities of family health teams. The storylines are rebinded by voices about the difficulties and the potential of educational processes for emancipator postures. For users, health education means proper care and information on disease prevention. Professionals understand that it is all information that is given to users, about health, social well-being, economic and general condition of human being as a way of preventing and treating disease. Mark printed on voices denote that activities and themes worked don‟t motivate users enough for their participation, being that physicians and dentists also get excluded themselves from educational practices. Elderly groups are those who get most involved with the activities. The size of the contained area and its seclusion from community make harder the access of users, as well as diminishing the quality of educational actions and links users-professionals. Therefore, the searching for medicines, medical consultations and wish to be well served are trademarks of voices from the users that interconnect with enlightening information and guidelines offered by professionals to users. It brings out practices that need to incorporate the social, the subjective and act with practices of prevention and health promotion, on the basis of lifestyles. The dialogical model, which needs to be approached since planning phase of health education actions could arouse interest of involved groups; promoting a relationship of dialogue and listening; discussing the local reality; stimulating practical methodological dialetics; promoting processes of deconstruction of concepts, values and attitudes, as more necessary than construction, using multiple languages. The defended thesis denotes paths to other studies aimed at understanding a dialogical template committed to exchanges of knowledge, and discover strategies that encourage formation of critical consciousness and the discovery of how is the training of new generations of healthcare professionals to belong to the project of society, in its technical, scientific, pedagogical, ethical, political and humanistic dimensions

A diversidade de lagartos na Caatinga é mediada pelos térmitas?

Intending to explain the extraordinary lizard coexistence levels found in Australian deserts, Morton & James (1988) figured out a hypothesis which defends that the termite diversity would bring about lizard radiation. This study aims to verify the validation of that hypothesis in Caatinga lizard assemblages. This study also objectives verifying if the termite defense mechanisms influence their consuming levels by lizards and if this pattern differs between different lizard lineages. Termites were collected using a standardized sampling protocol of termites. Besides using haphazard sampling, we collect lizards with 108 pitfall traps in each area. Intending to check the linkage between the termite and lizard assemblages, the lizard stomach contents were analyzed and then a canonical correspondence analysis was performed. The presence of nonrandom patterns of diet overlap among the lizard species was also examined. Aiming to check if the defense mechanisms of termite influence their consuming pattern by lizards it was performed a laboratory experiment where termite with different defense mechanisms were offered to lizards of two different lineages. We verified that lizard assemblages do not consume termites according to termite abundance in ecosystems. Furthermore, mean niche overlap lizard species did not differ significantly from that expected by chance. We found that termite chemical defense mechanism does influence the termite s pattern consuming by lizards. These results do not corroborate premises which support Morton & James hypothesis (1988) and point out that lizard do not chose termites based on their abundance, but, trying to avoid consuming termites which exhibit chemical defense mechanisms. This defense mechanism, however, may not be the only explanation to patterns of termite s consuming by lizards.

Assistência aos portadores de úlceras venosas: proposta de protocolo

Venous ulcers (VU), recurrent chronic wounds resulting from Chronic Venous Insufficiency (CVI), affect different age groups and would severely affect ambulation of patients. The lesions require treatment lasting and complex and are responsible for significant morbidity and mortality. Thus, this study aims to identify the important aspects covered in the scientific literature protocol for assisting patients with venous ulcers, identifying the issues to be proposed by the judges of the study (nurses, doctors and physiotherapists) to the protocol of care provided to patients venous ulcers and present the structure of protocol proposed by the judges of the study to assist patients with venous ulcers treated at a referral hospital of Rio Grande do Norte. This is a descriptive study using a quantitative approach, carried out at the dressings, located in the outpatient surgical clinic of the Hospital University Onofre Lopes (HUOL), located in East Sanitary District, Natal-RN. The sample consisted of 39 professionals, 30 nurses, seven doctors and two physical therapists, team members HUOL surgical clinic and other public and private institutions of Rio Grande do Norte and Jequié/Bahia. These professionals were the judges responsible for selecting the guidelines already proposed in the literature on VU protocols. Approved by the Ethics in Research HUOL (Report n.o 081/07), began the first stage of the study which consisted of reviewing the scientific literature about the relevant aspects to be included in a protocol for assisting patients with VU. These aspects were organized into a proposed questionnaire to the judges of the study. Following examination, held on the content validation with application of the Kappa (K), accepting a score higher than 0.80 and the Likert Scale, whereas rates from 4.0 to 5.0. The data collected were organized in Microsoft Excel and exported into Statistical Package for Social Sciences (SPSS) 15.0. The literature review included national and international scientific articles, thesis, dissertation and institutional protocols. Regarding the characterization of professional nurses predominated (76.1%), between 34 and 45 years (41.0%), female (79.5%), married/consensual union (46.2%), with specialization in VU care (61.5%), working in the hospital network (46.1%), with up to 5 years experience in VU (69.2%) and claiming to feel prepared to care for these injuries (92.3 %). With regard to aspects that had very good agreement (K ≥ 0.81), remained the items found in the literature with some modifications. In the analysis of the proposed evaluation items had very important, ranging from 4.1 (drug treatment) to 4.9 (patient assessment and care of the injury and the injured and perilesional skin). The proposition of the protocol is arranged in eleven items: A) Evaluation of patient and lesion, B) Registration and documentation, C) the wound and perilesional skin, D) an indication of coverage, E) Use of antibiotic and pain treatment, F) Surgical treatment of CVI, G) Drug treatment, H) Improving venous return and prevetion of recurrence, I) Referral of patients, J) Training and K) Reference and counter reference

Aconselhamento em HIV/AIDS: ações e reflexões dos profissionais do Centro de Testagem e Aconselhamento (CTA)

The counseling on HIV/Aids consists in a prevention strategy that contributes to increase the diagnosis of HIV and start earlier the treatment. The counseling has as pillars the emotional and educational support, risks evaluation that aim at the adoption of safe practices and the individual s responsibility for his own health. To accomplish these results, it is necessary that health workers understand counseling as a unique educational moment that stimulates the user s critical-reflection when it comes to his role as an active subject in this process. This study aimed to analyze the counseling on HIV/Aids conducted by the professionals of the Testing and Counseling Center (CTA), based on the educational perspective of Paulo Freire . This is a descriptive qualitative study with a critical reflexive design based on the principles of Action-Science. All the professionals acting as counselors in the Joao Pessoa, PB CTA, eight in total, took part in the study. Data were collected during the month of March, 2011, through non participative observation and semi-structured interviews with a critical-reflexive focus, analyzed according to the tenets of the critical-reflexive methodology, and discussed taking into consideration the Paulo Freire s pedagogy and pertinent literature. It was observed that most of the professionals expressed the work philosophy of CTA as the diagnosis and prevention of the disease, associated with the utilization and demonstration of condoms. However, upon observation of their counseling sessions, these ideas were not converted in actions. Educational themes were not covered and the condom wasn t offered at any time. The counseling actions focused on the provision of information and filling out the paper forms which are necessary for attendance. The sessions were conducted with brief dialogues and little opportunity for the users to expose or complement their thoughts and needs. The professionals mentioned as facilitating conditions for counseling, the team interaction and physical structure. The difficulties focused on the users low cognition, the large demand for attendance, aspects related to the service organization, and the counselors absences and delays. After reflecting about the actions observed in the counseling, the majority of professionals admitted the need to modify their practice in the incorporation of educational principles for the achievement of a broader prevention, and seemed to be willing to work in this perspective. In conclusion, although the counselors show ideas consistent with the purposes of CTA, these ideas are limited when it comes to the understanding of the meaning of prevention in HIV/Aids. Taking into consideration that they express a certain comprehension and act differently during the counseling, they demonstrate a lack of bond between the theories in use and the proposed ones, in accordance with the contribution of the action-science theory. The counseling, as an educative practice, doesn t materialize in the counseling itself and the orientation for reflection is not given during the attendance. These findings suggest the need to include the process of reflection in the execution of the actions of counseling, so that these practices are guided by reflexive practice, aiming at transforming the way of thinking and acting into a more educational perspective toward a more democratic and holistic assistance.

Estratégias de intervenção utilizadas por enfermeiros da ESF do município de Natal/RN no controle do câncer do colo de útero

Cancer of the cervix (cervical cancer) is the second most prevalent cancer among Brazilian women. The high rates of cervical cancer in Brazil justify the implementation of effective strategies to control this, which include actions to promote health, primary prevention, early detection, screening, treatment and palliative care. Despite the existence of the National Programme for Control of the CCU there was no reduction in the incidence and mortality of this disease in Brazil. The Family Health Strategy (FHS) has the potential to facilitate such control and, in this context, one should consider that nurses play a central role. The study aimed to know the general intervention strategies used by nurses FHS of Natal / RN in CCU control, and how specific: analyzing the knowledge of these nurses on the CCU, the actions developed in the ESF for the control of CCU and identify the difficulties faced by them to perform it. This is a descriptive exploratory quantitative developed through a structured interview guide with 106 nurses who have experience in controlling the CCU in FHS teams of Natal / RN. Data analysis was performed using descriptive statistic s. The results pointed to actions taken in the FHS to control the CCU, collection of cervical cancer screening, health education activities, nursing consultation, referral of suspected cases for medical monitoring and active women with abnormal test result . The actions that were not mentioned by the nurses included: forming groups of prevention and health promotion; expand coverage of exams and office hours of consultations, establishment of alternatives to end the pent-up demand in the health units, participation in treatment or rehabilitation process users with the CCU; interventions for pain management, alliances and partnerships with schools, in dustry and the use of protocols. This study can be seen that the practice nurses partially shares to the CCU in Natal / RN. The participants of this study, when asked about the CCU, specifically for signs and symptoms of disease and risk factors in general showed important gaps. Difficulties such as lack of materials for collection of Pap smear; inadequate physical space in the Health Units; pent-up demand in the service, delay in arrival of the test results; obstacles in the actions of referral and counter-referral and cultural factors make the CCU control is compromised. It is believed in this research contributed to a reflection on the importance of the role of nurses in the development of the ESF control actions CCU, pointing out the factors that affect these. It is important to involve all nurses who comprise the ESF as knowledgeable of the risk factors, signs and symptoms, and existing tools for the early detection of cervical cancer in the pursuit of quality improvement actions to promote women`s health, contributing in planning future interventions that may reduce mortality from this disease in Natal / RN.

Protocolo de avaliação do cuidado de enfermagem e da segurança do paciente em unidades de terapia intensiva

The reports of adverse events date from 1990 up to the present day. Conceptually, these adverse events are unintentional injuries unrelated to the underlying disease, causing measurable lesions in patients, extending the period of hospitalization, or leading to death. These issues require discussions with regard to patient safety, improved quality of service, and preventing medical errors. In the Intensive Care Units, this concern is greater because these are sectors of intensive care to individuals with hemodynamic changes and imminent risk of death. Therefore, it is essential to conduct evaluation processes to investigate aspects of quality of nursing care and patient safety in these spaces. For that reason, we aimed to propose the Evaluation protocol of nursing care and patient safety in Intensive Care Units. For its achievement, we needed to: 1) analyze the evolution of the patient safety concept used in scientific productions, under Rodgers evolutionary concept; 2) identify the necessary items to build the evaluation protocol of nursing care and patient safety in the Intensive Care Unit, from the available evidence in literature; 3) construct an instrument for content validation of the evaluation protocol of nursing care and patient safety in the Intensive Care Unit; and 4) describe and evaluate the appropriateness of the content for an evaluation protocol of nursing care and patient safety in the Intensive Care Unit. This is a methodological study for the content validation of the abovementioned protocol. To meet the first three specific objectives, we used the integrative literature review in Theses Database of the Coordination for the Improvement of Higher Education Personnel and the portal of the Collaborating Centre for Quality of Care and Patient Safety. The fourth specific objective happened through the participation of judges, located from the Lattes curricula, in the content validation process developed in two stages: Delphi 1 and Delphi 2. As instrument, we used the electronic form of Google docs. We present in tables the answers from the evaluation instruments by Delphi consensus and Content Validity Index (CVI) of the entire protocol. We summarized the results in articles entitled Analysis of the patient safety concept: Rodgers evolutionary concept ; Scientific evidence regarding patient safety in the Intensive Care Unit ; Technological device for the content validation process: experience report ; and Evaluation protocol of nursing care and patient safety in Intensive Care Units. The Embodied Opinion of the Research Ethics Committee of the Universidade Federal do Rio Grande do Norte, No. 461,246, under CAAE 19586813.2.0000.5537, approved the study. Thus, we conclude the protocol valid in its content, constituting an important tool for evaluating the quality of nursing care and patient safety in Intensive Care Units

Modelo de classificação para pequenas empresas supermercadistas quanto ao uso de técnicas de prevenção de perdas: um estudo de caso

The objective of this work is to draw attention to the importance of use of techniques of loss prevention in small retail organization, analyzing and creating a classification model related to the use of these in companies. This work identifies the fragilities and virtues of companies and classifies them relating the use of techniques of loss prevention. The used methodology is based in a revision of the available literature on measurements and techniques of loss prevention, analyzing the processes that techniques needed to be adopted to reduce losses, approaching the "pillars" of loss prevention, the cycle life of products in retail and cycles of continues improvement in business. Based on the objectives of this work and on the light of researched techniques, was defined the case study, developed from a questionnaire application and the researcher's observation on a net of 16 small supermarkets. From those studies a model of classification of companies was created. The practical implications of this work are useful to point mistakes in retail administration that can become losses, reducing the profitability of companies or even making them impracticable. The academic contribution of this study is a proposal of an unpublished model of classification for small supermarkets based on the use of techniques of loss prevention. As a result of the research, 14 companies were classified as Companies with Minimum Use of Loss Prevention Techniques - CMULPT, and 02 companies were classified as Companies with Deficient Use of Loss Prevention Techniques - CDULPT. The result of the research concludes that on average the group was classified as being Companies with Minimum Use of Techniques of Prevention of Losses EUMTPP, and that the companies should adopt a program of loss prevention focusing in the identification and quantification of losses and in a implantation of a culture of loss prevention

Uma arquitetura baseada em SCTP e SIP para suporte a aplicações VoIP móveis e a especificação formal do seu módulo de controle

New versions of SCTP protocol allow the implementation of handover procedures in the transport layer, as well as the supply of a partially reliable communication service. A communication architecture is proposed herein, integrating SCTP with the session initiation protocol, SIP, besides additional protocols. This architecture is intended to handle voice applications over IP networks with mobility requirements. User localization procedures are specified in the application layer as well, using SIP, as an alternative mean to the mechanisms used by traditional protocols, that support mobility in the network layer. The SDL formal specification language is used to specify the operation of a control module, which coordinates the operation of the system component protocols. This formal specification is intended to prevent ambiguities and inconsistencies in the definition of this module, assisting in the correct implementation of the elements of this architecture

Otimização de sistema de bombeamento com energia eólica: sistema de bombeamento de São Gabriel/BA

After the Protocol of Kyoto and of the ECHO 92 - Rio de Janeiro, the attentions of the world focus to the preservation of the environment and of the maintainable use of the natural resources. People were looking for preserving environment for the future generations. Ever since, solutions are looked for the supply of energy in its more acquaintances forms and the substitution of the use of fossil fuels for the such alternative forms as: Photovoltaics, solar heat systems for water, wind , bio-diesel, etc. and in this context the Company of Engineering of the State of Bahia - Cerb changed a diesel pumping system by an wind one, It´s the first community system of this nature in Bahia. Facing problems with the model, a Cerb involved the academic segment of the Federal Center of Technological Education of Bahia Cefetba looking for a solution. This work intends to demonstrate the possibilities of optimization of the pumping communit system that supply water to approximately 50 people in the place of Romão, municipal district of São Gabriel-Ba. Technical reports were published in AGRENERGD2004-Unicamp SP and Scientific Magazine ETC,Cefetba, 2005. A simulation of the increase of energy is presented for heights of 15 and 20m, considering the eletromecanical balance from the pumping energy to the wind turbine. From the accomplished bibliographical revision, we emphasized the mechanical aspects of the engineering once in UFRN, those studies concentrate on the Department of Mechanical Engineering while, in others eletroelectronic are more emphasized. Finally, documents that we judged important were enclosed for the perfect understanding of this work

Efeito imediato da estimulação elétrica neuromuscular seletiva do músculo VMO em pacientes com síndrome da dor femoropatelar

Patellofemoral pain syndrome (PFPS) is described as anterior or retropatellar pain knee in the absence of other pathologies and is frequently associated with dysfunction of the vastus medialis oblique (VMO). However, several studies have demonstrated the inability to selectively activate this muscle through exercise. To evaluate the effect of Neuromuscular Electrical Stimulation (NMES) selective VMO in women with syndrome. We evaluated thirty-eight women: twenty in the control group (24.15 ± 2.60 years) and eighteen diagnosed with PFPS (25.56 ± 3.55 years). Both groups were evaluated before and after a protocol of electro stimulation. To measure for comparing groups before and after treatment, we assessed the extensor torque concentric and eccentric knee through an isokinetic dynamometer, the intensity (Root Mean Square - RMS) and the onset of activation (onset) of VMO compared to the vastus lateralis (VL) in two types of exercise: open and closed kinetic chain. . Statistical analysis was performed using SPSS 15.0, with a significance level of 5%. Results: Our data showed an increase in the intensity of activation (RMS) of the VMO muscle after NMES in both study groups. During concentric contraction the RMS of the VMO before the NMES was 105.69 ± 32.26 μV and after a single intervention was 122.10 ± 39.62 μV (p = 0.048) for the control group. In the group with PPS, we found a similar behavior, with RMS of the VMO before NMES of 96.25 ± 18.83 μV and 139.80 ± 65.88 μV after the intervention (p = 0.0001). However, there was no evidence in the RMS value of VL muscle. The onset was calculated by subtracting the onset of VL by the onset of VMO. For the group with PFPS, the onset before the intervention was -0.007 ± 0.14 ms, indicating a delay of the VMO relative to VL, and after NMES was 0.074 ± 0.09 ms (p = 0.016), showing an activation previous VMO to VL. The same occurred for the control group. We also observed that NMES increased knee extensor power during the concentric contraction in both groups. Before the intervention the mean power was 28.97 ± 9.01 W for the PPS group and after NMES was 34.38 ± 7.61 W (p = 0.0001). Conclusion: We observed an increase in electromyographic activity of the VMO and also an anticipatory effect of this muscle
