This diploma thesis deals with the topic of clients after lower limb/s amputation and their social rehabilitation afterwards in home care. Beginning of thesis describes the current situation and the concept of social rehabilitation as one of the comprehensive rehabilitation process of people in early post-amputation stage. Next section of thesis shows difficulties that occurs after amputation and impact upon personal life that is materially changed. Describing the process of coping with this unpleasant health change is based on traditional model of two important people in this field Mr. Kübler-Ross and Mr. Křivohlavý. At the same time, analysis of the formal support system in Ústí nad Labem is being evaluated. This system provides support not only to disabled people but also to people who take infromal care of the one injured. Informal care plays significant role in the process of social rehabilitation of people starting new life stage due to physical change. In thesis are mentioned possibilities of developing skills of informal caregivers, usage of financial benefits for disabled people and possible providers support of medical and social services in a given location. However, it also focuses on possible troubles associated with care provided by family members or other persons. At the same time,...

Bakgrund Amputation innebär att individen förlorar en liten eller stor del av kroppen som inte kan ersättas. Orsaken till amputation kan vara kärlsjukdomar, diabetes samt trauma. Amputation kan medföra fysiska och psykiska förändringar i patientens liv. Omvårdnad av dessa patienter kan vara komplex, sjuksköterskan har i sin profession en betydande roll i mötet med patienten. Syfte Syftet var att beskriva patienters upplevelser och erfarenheter efter amputation av nedre extremitet. Metod En icke systematisk litteraturöversikt genomfördes utifrån Fribergs metodbeskrivning. Sjutton originalartiklar inhämtades via databaserna PubMed och Cinahl Complete. Valda artiklar, kvalitetsgranskades och analyserades genom en integrerad analysmetod. Resultat Efter sammanställning av de nitton studierna identifierades två övergripande rubriker: Fysiologiska upplevelser och erfarenheter, psykologiska upplevelse och erfarenheter. varje kategori hade två underkategorier. Eftersom vi undersöker patientens upplevelser och erfarenheter efter amputation har vi valt att inkludera flera faktorer som påverkar patientens livskvalitet såsom sexualitet, smärta, depression och kroppsbild. Dessutom har vi även valt att inkludera benprotesens samt ADLs funktion som en faktor eftersom funktionaliteten är en viktig del av livskvaliteten. Slutsats Amputation leder till stor förändring i patientens liv, kan orsaka lidande i både den fysiska och psykiska hälsan, och ger svårigheter i patientens framtida liv. Det är viktigt som sjuksköterska att förstå och ha kunskap om den påfrestning som uppkommer efter amputation för att ge den specificerade vård som behövs i samarbete med andra yrkesgrupper för att möjliggöra att patienten ska kunna återgå till ett så normalt liv som möjligt. / Background Amputation means that the individual loses a small or large part of the body which cannot be replaced. The cause of amputation can be vascular disease, diabetes and trauma. Amputation causes physical and mental changes in the patient's life. Patient care can be complex, therefore the nurse has a significant role when interacting with patients who have undergone amputation. Purpose The purpose was to describe patients experiences after amputation of the lower extremity. Method Non-systematic literature review was performed based on Friberg's method description. Seventeen original articles were obtained via the databases PubMed and Cinahl Complete. Selected articles were quality reviewed and analyzed through an integrated analysis. Results After compiling the seventeen studies, two main categories were identified: Physiological experiences and experiences, psychological experience and experiences. Each category had two subcategories. Because we examine and study the patient's experiences after amputation, we have chosen to include several factors that affect the patient's quality of life such as sexuality, pain, depression and body image. In addition, we have also chosen to include the function of bone prosthesis and ADL as a factor because functionality is an important part of the quality of life. Conclusions Amputation leads to great change in the patient's life, which can cause suffering in physical and mental health and difficulties in the patient's future life. It is important as a nurse to understand and have knowledge of the stress that arises after amputation to provide the specified care needed in collaboration with other professions to enable the patient to return to a normal life as possible.

Les amputations d’un membre supérieur sont non seulement dévastatrices pour le bien-être physique, psychologique et social des patients, mais elles comportent également des répercussions financières importantes pour l’individu et le système de santé. Les allotransplantations de tissus composites vascularisés ont été proposées en tant que solution permettant de rétablir la forme et la fonction au détriment d’une immunosuppression à vie et d’un taux élevé de rejet chronique. Les prothèses myoélectriques combinent l’expertise chirurgicale avec les avancées technologiques pour réhabiliter les fonctions motrices d’un moignon amputé, mais elles demeurent limitées par un taux élevé d’abandon et des coûts importants. Dans les systèmes de santé avec des ressources limitées, les dirigeants ont la tâche complexe de partager équitablement l’allocation de ressources entre plusieurs maladies et interventions. Dans le domaine de l’économie de la santé, les analyses de type coût-bénéfice ont été développées pour répondre à ces questions. Les mesures d’utilité doivent incorporer l’impact que le traitement suscite sur l’espérance de vie et la qualité de vie. Ces utilités sont ensuite rapportées en fonction du coût, ce qui permet aux dirigeants de la santé de déterminer dans quels traitements il serait préférable d’investir les ressources. Dans cette thèse, nous proposons un modèle pour étudier les coûts-utilité des allotransplantations de la main et des prothèses myoélectriques. Pour commencer, une étude pilote a été effectuée sur les amputations du pouce traitées avec des lambeaux libres de l’orteil, ce qui nous a permis de confirmer la faisabilité des questionnaires d’utilité conçus. Par la suite, les utilités ont été mesurées dans une population d’amputés du membre supérieur, de patients réimplantés proximalement et de contrôles en santé. Les résultats démontrent que 1) les patients réimplantés rapportent la meilleure utilité avec les prothèses myoélectriques, 2) les amputés unilatéraux préfèrent significativement les prothèses myoélectriques également, et 3) aucune différence n’a été recelée entre les deux traitements chez les amputés bilatéraux. Au final, une analyse des coûts-bénéfices a été effectuée dans le contexte du système de santé canadien, démontrant que le traitement des patients amputés unilatéralement avec des prothèses myoélectriques permettrait de sauver davantage de coûts, alors que l’écart en épargnes monétaires se rétrécit pour les amputés bilatéraux traités avec une allotransplantation ou une prothèse. Avec les résultats rapportés dans cette thèse, nous pouvons proposer une mise à jour des indications de traitements pour les patients avec une amputation du membre supérieur. Basé sur l’analyse de type coût-utilité, nous concluons que les amputés unilatéraux sont de meilleurs candidats pour des prothèses myoélectriques, alors que les deux traitements sont encore adéquats pour les amputations bilatérales. / Amputations of the upper extremity are not only devastating for the patient’s physical, psychological and social well-being, but they also yield significant financial repercussions to the individual and the healthcare system. Vascularized composite allotransplantations of the upper extremity were proposed as a solution to restore form and function, albeit to the detriment of lifelong immunosuppression and high rates of chronic rejection. New-generation myoelectric prostheses combine surgical prowess with technological refinements to rehabilitate motor functions of the amputated stump, but remain plagued by high rates of abandonment and significant costs. In healthcare systems wherein resources are limited, financial regulators have the difficult task of proposing an equitable divide of resource allocations between a multitude of diseases and interventions. In the field of health economics, cost-benefit analyses were developed to assist in this decision-making process. Utility outcome measures need to encompass the impact that a treatment elicits on life expectancy and quality of life. Comparison of utilities of different interventions as a function of cost further indicates which route healthcare regulators should partake. In this thesis, we propose a model to study cost-utilities of hand allotransplantation and myoelectric prostheses. To begin, a pilot study was performed on thumb amputations treated with free toe flaps, which allowed to confirm the feasibility of the utility questionnaires that we developed. Afterwards, utilities and quality adjusted life years were measured in a population of upper extremity amputees, proximally replanted patients and healthy controls. Findings demonstrated that 1) replanted patients reported the highest utility outcomes for myoelectric prostheses, 2) unilateral amputees significantly preferred myoelectric prostheses as well, and 3) no significant preference between both interventions was obtained in patients with bilateral amputations. Finally, a cost-benefit analysis was performed in the context of the Canadian healthcare system, demonstrating that significant savings can be achieved with treatment of unilateral amputations with myoelectric prostheses, whereas the gap in cost savings between both treatment groups becomes less significant in bilateral amputees. With the findings reported in this thesis, we can propose an update of the indications for treatment in patients with upper extremity amputations. From the perspective of cost-utility analyses, we conclude that unilateral amputees are better candidates for myoelectric prostheses, and that both treatments can still be offered in cases of bilateral amputations.

Author: Bc. Michaela Richtrová Tittle: Golf swing in subjects with amputation of lower extremity Objectives: The study aims at evaluation of the technique of golf swing used by patients with a different type and level of lower extremity amputation as compared to able-bodied golfers. Another objective is determination of the relation between individual phases of the golf swing and weight transfer, using different golf clubs, as compared to able-bodied golfers. Method: By its topic the work is a pilot study. The research has been divided into three descriptive case studies. The experimental group included two amateur golfers and one professional golfer. The control group was represented by an able-bodied golfer. Evaluation of kinematic parameters (trajectory of shoulders, hips, knee joints) was based on the Qualysis Motion Capture System. Evaluation of dynamic parameters (weight transfer) in the course of golf swing was made using two dynamometric Kistler platforms. Results: The measuring has demonstrated that in terms of both kinematics and dynamics, the mode of movement of a patient with a trans-tibial amputation during a golf swing corresponds to that of an able-bodied golfer. The same results were achieved by the patient also with the use of another type of golf club. A change, both in terms of...

The aim of this study was to develop methodics of occupational therapy for patients with moelectric prosthesis, which is used by patients with amputation of upper limbs as well as patients with congenital problems. In the Czech republic there are no complex methodics about occupational therapy and myoelectric prosthesis, despite the huge mount of foreign studies of this topic. Myoelectric prosthesis uses the principle of sensing myoelectrical signals which are then transformed to the motor output in the terminal portion of the prosthesis. Occupational therapy intervention begins at the preprosthetic phase, the occupational therapist assesses the general potential for the use of myoelectric prosthesis and picks up myoelectric signals from the stump. In interprosthetic phase occupational therapist is dedicated to the training of activities of daily living with myoelectric prosthesis and training residual stump on the basis of myotest. The phase after prosthetic content of occupational therapy evaluation and assessment, which focus on patients ability of myoelectric control and prosthesis involvement in activities of daily living and training of grip. Within the training of grip, occupational therapist is dedicated to training proper grip within the pace, grip strength and targeted movements. The...

Introdução: Pacientes submetidos à amputação de membro inferior por doença arterial obstrutiva periférica (DAOP) estão em risco para o desenvolvimento de trombose venosa profunda (TVP). Há poucos estudos na literatura sobre a incidência no pós-operatório precoce e quanto aos fatores de risco no desenvolvimento da TVP no membro amputado. Objetivo: A finalidade deste estudo é avaliar, de modo prospectivo, a incidência de trombose venosa profunda pós-operatória em até 35 dias, em pacientes submetidos à amputação de membro inferior por doença arterial obstrutiva periférica, sua relação com comorbidades e com óbito. Método: De setembro de 2004 a março de 2006, foram estudados 56 pacientes (29 homens; média de idade 67,25 anos) submetidos a 62 amputações (36 transtibiais e 26 transfemorais), utilizando-se eco-Doppler no pré-operatório e aproximadamente no 7º e 31° dia de pós-operatório. Resultado: Houve TVP em 16 (25,8%) membros amputados, sendo 10 casos em amputações transfemorais e 6 casos em transtibiais. A incidência cumulativa no período até 35 dias foi de 28% (Kaplan-Meier). Houve diferença significativa na incidência de TVP entre amputações transfemorais (37,5%) e transtibiais (21,2%), p = 0,04. Outro fator de risco para TVP foi idade igual ou superior a 70 anos (48,9 vs 16,8%, p=0,021). Houve 01 caso de embolia pulmonar sintomática não fatal em paciente com TVP já diagnosticada. Não houve relação entre outras comorbidades e TVP. A trombose venosa no membro amputado não influenciou na taxa de óbito que foi de 9,7%. Conclusões: A incidência de TVP no pós-operatório recente (até 35 dias) foi elevada principalmente em pacientes com idade igual e superior a 70 anos e nas amputações transfemorais. Os pacientes com DAOP submetidos a grandes amputações devem ser considerados de alto risco para TVP, mesmo após alta hospitalar. / Introduction: Patients undergoing amputation of the lower limb due to Peripheral Arterial Disease (PAD) are at risk for developing Deep Venous Thrombosis (DVT). There are few studies in the research literature on the incidence of DVT during the early postoperative period and the risk factors for the development of DVT in the amputation stump. Objective: The goal of this prospective study was to evaluate the incidence of deep venous thrombosis during the first 35 postoperative days in patients who had undergone amputation of the lower extremity due to PAD, and its relation to comorbidities and death. Method: From September 2004 to March 2006, fifty-six patients (29 men, mean age 67.25 years) underwent 62 amputations (36 below knee amputation BKA and 26 above knee amputation- AKA), and echo- Doppler scanning on preoperative, and approximately the seventh and 31st postoperative days. Results: DVT occurred in 16 (25.8%) of the amputated extremities, (10 AKA and 06 BKA). The cumulative incidence in the 35 day postoperative period was 28% (Kaplan-Meier). There was a significant difference in the incidence of DVT between AKA (37.5%) and BKA (21.2%), p = .04. Another DVT risk factor was age equal to or above 70 years (48.9 vs. 16.8%, p= .021). There was one case of symptomatic non-fatal pulmonary embolism in a patient already diagnosed with DVT. There was no relation between other comorbidities and DVT. Venous Thrombosis in the amputation stump did not influence the mortality rate which was 9.7%. Conclusions: The incidence of DVT in the early post-operative period (up to 35 days) was elevated mainly in patients 70 years of age or older and in AKA. Patients with PAD who have recently undergone major amputations should be considered at high risk for DVT, even after hospital discharge.

Este trabalho surgiu a partir da experiência como psicóloga do Instituto de Ortopedia e Traumatologia do Hospital das Clínicas da faculdade de Medicina da Universidade de São Paulo. Mais especificamente ao longo dos anos trabalhando no Grupo de Prótese e Órteses, com pessoas que sofreram amputação de um ou mais membros. A perda de uma parte do corpo implica alterações significativas na vida de um indivíduo, sendo que as amputações decorrentes de acidentes em geral têm a característica de serem súbitas e imprevisíveis, ocasionando mudanças bruscas para as quais não existe preparo possível. A principal questão que norteou este trabalho diz respeito às conseqüências psíquicas que uma perda física pode ocasionar. Procurou-se compreender de que forma, diante de uma ruptura no corpo, há uma interferência na organização psíquica e na maneira pela qual o indivíduo percebe o mundo e se percebe nele; isso, durante o período de reabilitação. Buscou-se refletir sobre um momento de perda da integridade corporal e seus reflexos na unidade psicossomática, a partir de casos clínicos, tendo como referência a psicanálise winnicottiana. Dessa forma, levou-se em conta o percurso do desenvolvimento emocional segundo a teoria do amadurecimento pessoal de D.W.Winnicott para se refletir acerca da possível relação existente entre o estágio alcançado nas tarefas próprias do desenvolvimento normal pelo indivíduo e as conseqüências em termos da continuidade ou não do processo de amadurecimento após a amputação. Para esta investigação utilizou-se o método clínico e o referencial psicanalítico, sendo que para a análise da questão proposta neste trabalho foram apresentados quatro casos clínicos. A perda de uma parte do corpo ocasionou mudanças em todos os indivíduos que fizeram parte deste estudo. Mudou o corpo, a forma de se locomover, o trabalho, o sustento pessoal e familiar, o contato social. Porém a maneira por meio da qual cada um percebeu, significou e vivenciou essa perda e essas mudanças não foi equivalente nem determinada pela qualidade da perda. Assim, concluímos que as conseqüências psíquicas de uma perda física serão aquelas relativas às condições que cada indivíduo tem de elaborar imaginativamente essa perda e transformá-la em vivência, experiência, história pessoal e interpessoal. A articulação da teoria com a análise e discussão do material clínico permitiu perceber que não é possível caracterizar uma clínica dos amputados. Isso porque o que temos são tantas clínicas quanto nos for possível conhecer os indivíduos amputados em seu processo de amadurecimento pessoal anteriormente à amputação. Ou seja, uma amputação não direciona incondicionalmente o modo de um indivíduo estar no mundo, mas implica alterações significativas em sua existência, o que remete à necessidade de reformulações em sua identidade para incluir essa nova dimensão de experiência. A dificuldade em realizar a elaboração imaginativa dessa perda, pode tornar a amputação um acontecimento não integrado na vida de uma pessoa, com conseqüências prejudiciais à sua saúde e ao seu desenvolvimento. / This work arose from the experience as a psychologist in the Institute of Orthopedist and Traumatology of the Hospital das Clinicas of the faculty of Medicine of the University of São Paulo. More specifically along the years working on the Group of Prothesis and Orthesis, with people that suffered amputation of one or more members. The loss of a part of the body involves significant changes in the life of a person. The amputations originated from accidents in general have a characteristic of being sudden and unpredictable causing abrupt alterations in which no preparation is made possible. The main subject which directed this work concerns the psychic consequences that a physical loss causes. We intend to understand in what way, from a rupture of the body, there is the interference of the psychic organization and in what way the person notices the world and perceives himself in it; this, during the period of rehabilitation. We wanted to reflect about the moment of the loss of the integrity of the body and its reflexes on the psychosomatic unit, from clinical cases, with the theoretical reference of maturing of D. W. Winnicott. In this way, we took into account the course of the emotional development according to the theory of personal maturing to reflect about the possible relation existing between the stages reached on the proper tasks of the normal development of the person and the consequences in terms of continuity or not of the process of maturing after the amputation. For this investigation we used the clinical method and the psychoanalysis reference. For the analysis of the subject proposed in this work we presented four clinical cases. The loss of a part of the body caused changes in all of the persons which were part of this study. Changed the body, the way to move, the job, the personal and family maintenance, the social contact. In the other hand the way through which each one perceives, signifies and lives this loss and these changes was not equivalent nor determined by the quality of the loss. This way, we conclude that the psychic consequences of a physical loss are those related to the conditions that each person has to elaborate imaginatively the loss and transform it in a way of life, experience, personal and interpersonal story. The articulation of the theory with the analysis and discussion of the clinical material permitted to notice that it is not possible to characterize a clinic of the amputated. This because what we have are as many clinics as we are able to know the amputated persons in their process of personal maturing previous to the amputation. Or else, an amputation does not direct unconditionally the way that a person exists in the world, but implies in significant alteration of his existence, what refers to a need of reformulations in his identity to include this new dimension of experience. The difficulty in accomplishing the imaginative elaboration of this loss, can transform the amputation in a non integrated occurence in the life of a person, with bad consequences to his health and to his development.

Introdução: O amputado transfemoral apresenta alterações anatômicas e funcionais importantes que se manifestam na marcha e nas atividades diárias. Apesar do lado envolvido na amputação apresentar menor força, não se sabe ao certo se há alguma posição angular ou velocidade angular específica em que isso ocorre, o tipo de contração muscular mais acometido e, além disso, se o lado não envolvido na amputação, também, possui variações da força muscular. Objetivos: Avaliar o torque e trabalho nos músculos do quadril através da dinamometria isocinética nos amputados transfemorais, em contrações isométricas, concêntricas e excêntricas dos músculos do quadril dos amputados transfemorais e comparar estes valores com o lado não envolvido pela amputação e grupo controle. Casuística e Método: A característica do estudo é do tipo transversal, no qual 23 sujeitos do sexo masculino, sedentários, foram divididos em dois grupos. O grupo controle foi constituído de 13 sujeitos com média de idade de 27,2 ± 7,6 anos, massa corporal de 69,7 ± 9,9 kg, e estatura de 1,74 ± 0,05 m. O grupo de amputados foi constituído de 10 (dez) sujeitos amputados transfemorais, com 37,7 ± 12,5 anos de idade, massa corporal de 63,9 ± 7,5 kg e estatura média de 1,70 ± 0,09 m. O dinamômetro isocinético Biodex modelo System 3 Pro foi utilizado para as coletas dos dados isométricos e dos movimentos isocinéticos, tanto para contração muscular concêntrica quanto para contração excêntrica. As posições angulares foram de 0º,10º, 20º e 30 º de abdução do quadril, para os grupos adutores e abdutores, e 0º, 30º, 60º e 90º para os grupos flexores e extensores. As contrações concêntricas e excêntricas foram avaliadas nas velocidades angulares de 30º/s, 90º/s e 150º/s. Resultados: O grupo amputado apresentou reduções significativas do torque e trabalho no lado envolvido nas contrações isométricas, principalmente nas posições de maior grau de alongamento muscular. Os achados das contrações concêntricas e excêntricas mostraram que o lado envolvido e não envolvido têm menores torque que o grupo controle, principalmente em maior velocidade. O grupo adutor do quadril tem importante diminuição de força em ambos os lados no amputado. Interessantemente, o torque e trabalho dos músculos extensores do quadril, nos amputados, em ambos os lados, foram maiores que o grupo controle, o que indicar uma adaptação dos músculos ao uso da prótese. A variável trabalho pode ser importante para revelar as condições musculares desta população. Conclusão: Os achados do presente estudo mostraram que os amputados transfemorais têm alterações no torque e trabalho mecânico gerados pelos músculos do quadril, no lado envolvido e não envolvido, dependendo da velocidade angular e da posição da articulação. / Introduction Amputation at the transfemoral level leads to anatomical and functional adaptations that change the gate pattern and influences daily-life activities. It is well known that the side of the amputation presents lower force. However, it is not known if there is a specific angular position or angular velocity in that the force is even lower. Moreover, how amputation affects the type of muscular contraction and the force generated in the contralateral side needs further investigation. Objectives: to investigate torque and mechanical work generated by hip muscles in transfemoral amputees subjects during concentric and eccentric isometric contractions. Furthermore, to compare these parameters with the non-involved side and a control non-amputee group. Methods: Thirteen subjects (mean age ±SD, 27,2 ± 7,6 years, mean height ± SD, 1,74 ± 0,05 cm, mean weight 69,7 ± 9,9 kg) in the control group and ten (mean age ±SD, 37,7 ± 12,5 years, mean height ± SD, 1,70 ± 0,09 cm, mean weight 63,9 ± 7,5 kg) in the amputee group participated in the study. A dynamometer Biodex System 3 Pro was used to measure torque and mechanical work in four (0º, 10º, 20º e 30) hip abduction positions during hip abduction and adduction efforts, and four (0º, 30º, 60º e 90) hip abduction positions during hip flexion and extension. Concentric and eccentric contractions were evaluated during 30º/s, 90º/s and 150º/s. Results: The amputee group presented significant reduction in the isometric torque generated in the ipsilateral side, mainly when the muscle was further stretched. For concentric and eccentric contractions, in high angular velocity, the control group presented significantly higher torque values when compared with the both sides of the amputee group. Interestingly, the torque and mechanical work generated by the amputee group, in both sides, were significantly higher compared with the control group. Mechanical work might be an important parameter to understand muscular conditions in the amputee population. Conclusion: The present study showed that transfemoral amputees have alterations in hip muscles torque and mechanical work generation, in the involved and uninvolved side, according to the joint position and angular velocity.

Objective: The goal of this prospective study was to evaluate the incidence of deep venous thrombosis during the first 35 postoperative days in patients who had undergone amputation of the lower extremity due to PAD, and its relation to comorbidities and death. Method: From September 2004 to March 2006, fifty-six patients (29 men, mean age 67.25 years) underwent 62 amputations (36 below knee amputation BKA and 26 above knee amputation- AKA), and echo- Doppler scanning on preoperative, and approximately the seventh and 31st postoperative days. Results: DVT occurred in 16 (25.8%) of the amputated extremities, (10 AKA and 06 BKA). The cumulative incidence in the 35 day postoperative period was 28% (Kaplan-Meier). There was a significant difference in the incidence of DVT between AKA (37.5%) and BKA (21.2%), p = .04. Another DVT risk factor was age equal to or above 70 years (48.9 vs. 16.8%, p= .021). There was one case of symptomatic non-fatal pulmonary embolism in a patient already diagnosed with DVT. There was no relation between other comorbidities and DVT. Venous Thrombosis in the amputation stump did not influence the mortality rate which was 9.7%. Conclusions: The incidence of DVT in the early post-operative period (up to 35 days) was elevated mainly in patients 70 years of age or older and in AKA. Patients with PAD who have recently undergone major amputations should be considered at high risk for DVT, even after hospital discharge.
