RESUMO
A definição de amputação compreende a separação total ou parcial de um membro do resto do corpo, com finalidade de proporcionar alívio à dor ou evitar a morte. Apesar de ser algo ocorrido no corpo físico e de cunho reconstrutor, também pode gerar impactos psíquicos a quem vivencia. Objetivos: A presente pesquisa tem como objetivo realizar um estudo qualitativo sobre como as pessoas que sofreram amputação de membros inferiores (MMII) lidam com o processo de mudança corporal e a vivência do luto. O desenvolvimento deste estudo justifica-se pelo avanço no campo da investigação do processo associado à cirurgia de amputação e seus aspectos psicológicos. Isso possibilita uma possível contribuição para a compreensão de como esses sujeitos vivenciam o processo de luto e a reintegração de sua imagem corporal, uma vez que a amputação pode trazer consequências em diversas áreas da vida do paciente. Metodologia: O estudo foi realizado através de uma amostragem intencional, composta por seis participantes, submetidos à amputação de membros inferiores, internados em um hospital de urgências. Para isso foram realizadas duas entrevistas semiestruturadas, utilizadas em dois momentos: após a indicação clínica de amputação e no pós-operatório, após a retirada do membro. Posteriormente, as entrevistas foram analisadas por meio da técnica de análise de conteúdo. Resultados e Discussão: A partir das entrevistas realizadas, emergiram diversos conteúdos emocionais. Assim, compreendeu-se que a amputação, em grande medida, assumiu um caráter traumático para os sujeitos, sobretudo considerando-se as especificidades de cada situação em particular. Conclusões: Mediante o estudo realizado, concluiu-se que o acompanhamento psicológico nesse cenário visa a manejar o impacto psicológico que a perda do membro pode ocasionar na vida do paciente, auxiliando na construção de uma nova imagem corporal, permitindo, assim, que o sujeito possa lidar com as decorrentes repercussões emocionais
The definition of amputation comprises the complete or partial separation of a limb from the rest of the body, with the purpose of providing pain relief or preventing death. Although it is something that happens in the physical body and has a reconstructive nature, it can also generate psychological impacts on those who experience it. Objectives: The objective of this research is to conduct a qualitative study on how individuals who have undergone lower limb amputations cope with the process of bodily changes and the experience of mourning. The development of this study is justified by the advancements in the field of investigation regarding the amputation surgery process and its psychological aspects. This allows for a potential contribution to the understanding of how these individuals experience the mourning process and the reintegration of their body image, as amputation can have consequences in various areas of the patient's life. Methodology: The study was conducted through intentional sampling, consisting of six participants who had undergone lower limb amputations and were hospitalized in an emergency hospital. Two semi-structured interviews were conducted, used at two moments: after the clinical indication of amputation and post-operative limb removal, and later analyzed using content analysis technique. Results and Discussion: Several emotional contents emerged from the interviews conducted. Thus, it was understood that amputation, to a great extent, assumed a traumatic character for these individuals, especially considering the specificities of each particular situation. Conclusions: Based on the conducted study, it was concluded that psychological support in this scenario aims to manage the psychological impact that limb loss can cause in the patient's life, assisting in the construction of a new body image and enabling the individual to cope with the resulting emotional repercussions

As an important auxiliary tool for amputees to gain abled limb functions, prosthetic limbs with decoration or feedforward control channel could not meet the needs. In order to enable the prosthesis to deliver the information, includes temperature, pressure, position, shape and so on, a variety of sensory feedback methods have been integrated into the prosthesis. According to the position of the feedback terminal on the human body, the perceptual feedback systems include invasive and noninvasive sensory feedback. This review presents the research progress of these perceptual feedback techniques, and summarizes the problems in the application in artificial limbs. Finally, the development trend of sensory feedback technology in prostheses is prospected.

SUMMARY OBJECTIVE: Few physical exercise programs for children with limb loss have been described in detail recently. We provided information regarding the characteristics and effectiveness of an alternative rehabilitation exercise developed for children with lower-limb amputation. METHODS: An 8-year-old boy with a below-knee amputation and a 9-year-old bilateral amputee girl performed an exercise program of one 2-h session per week for 20 weeks, aimed at developing muscular strength and coordination. Walking ability and walking speed were assessed by using the L-test of functional mobility and 10-m walk test, respectively. Mechanical and neuromuscular muscle function was assessed by using tensiomyography. RESULTS: In case 1, a decrement of 9.5% and 10.5% was found in the L-test (42 s vs. 38 s) and in the 10-m test (19 s vs. 17 s) scores, respectively. In case 2, walking ability remained unchanged (L-test score: 38 s), while a 5.2% reduction in walking speed was observed (10-m test score: 19 s vs. 18 s). No relevant changes were observed in the muscular tone in both cases. CONCLUSIONS: Practitioners should be aware that, contrary to what could be expected, a multidisciplinary training program held once per week for 5 months had a minimal impact on the gait pattern and neuromuscular function of two children with lower-limb amputation.

OBJECTIVES: To evaluate how transtibial amputation (TT) affects bodyweight distribution, voluntary knee joint position sense (JPS), and quadriceps (QUA) and hamstrings (HAM) strength in prosthetized patients. METHODS: Only TT patients who had been prosthetized for more than one year were included, and an age-paired able-bodied group was used as control. The participants stood on force plates with their eyes open to measure bodyweight distribution between the limbs. Knee voluntary JPS was assessed by actively reproducing a set of given arbitrary joint angles using a video analysis approach, and QUA and HAM strength were assessed isometrically with a hand-held dynamometer. RESULTS: Sixteen TT subjects (age: 39.4±4.8 years) and sixteen age-paired control subjects (age: 38.4±4.3 years) participated in the study. The amputees supported their bodyweight majorly on the sound limb (54.8±8.3%, p<0.001). The proprioceptive performance was similar between the amputated (absolute error (AE): 2.2±1.6°, variable error (VE): 1.9±1.6°, constant error (CE): -0.7±2.0°) and non-amputated limbs (AE: 2.6±0.9°, VE: 2.1±0.9°, CE: 0.02±2.3°), and was not different from that of control subjects (AE: 2.0±0.9°, VE: 1.4±0.4°, CE: -1.1±1.7°). There was a considerable weakness of the QUA and HAM in the amputated limb compared with the sound limb and control subjects (p<0.001 both). CONCLUSIONS: The asymmetric bodyweight distribution in the transtibial amputees was not accompanied by a reduction in knee proprioception. There was significant weakness in the amputated limb, which could be a potential issue when designing rehabilitation programs.

Abstract Aim: The purpose of the study was to assess upper limbs' maximum power and locomotion speed among amputee football (amputee soccer) players. Methods: The 30-s Wingate Anaerobic test and the 20-m sprint test were performed. Anthropometric measurements and body composition (Body mass index (BMI), percentage of body fat (% BF), and lean body mass (LBM)) were examined. Results: BMI significantly differentiated forwards and defenders (p < 0.05). Peak power (PP) and mean power (MP) were related to LBM (p < 0.05), thus defenders reached higher values of PP, in comparison to forwards. % BF and BMI were related to relative mean power (rMP) (p < 0.05). Field position differentiated players in terms of upper limbs' relative peak power (rPP) in favour of forwards (p < 0.05). Age was a significant factor for speed velocity on 10 m and 20 m (p < 0.05). There was no relationship between upper limbs' power and locomotion speed. Conclusion: Body composition, especially % BF may influence on the anaerobic performance of amputee football players.

INTRODUÇÃO: A intervenção em realidade virtual (RV) foi viável em amputados de membros inferiores (AMI). Até onde sabemos, não existe um estudo controlado randomizado disponível sobre a reabilitação do AMI usando RV. As evidências sugerem que são necessárias mais pesquisas para reabilitação de amputados usando VR. OBJETIVO: Comparar a eficácia da terapia de RV como um complemento terapêutico adicional com o protocolo de fisioterapia nos limites de estabilidade e estabilidade postural, dor e qualidade de vida entre os AMI. MÉTODOS: Um total de 100 AMI foi recrutado por amostragem aleatória simples (gerador de número aleatório) do JPN Apex Trauma Center, AIIMS, para participar de um ensaio clínico randomizado. O AMI recrutado foi dividido aleatoriamente em dois grupos: terapia de realidade virtual juntamente com o grupo protocolo de fisioterapia (VRT-PTP) e o grupo protocolo de fisioterapia (PTP). A duração do tratamento será de 30 minutos em uma sessão / dia, durante 4 dias / semana, durante 3 semanas. Assim, cada AMI receberá 12 sessões no total. O Sistema de Equilíbrio Biodex para medir o equilíbrio dinâmico, NPRS para dor e qualidade de vida pelo WHOQOL-BREF da OMS (WHOQOL-BREF) são as medidas de resultado que serão registradas na linha de base, no final do período pós-intervenção de três semanas. O acompanhamento será realizado na 6ª e 9ª semana após a inscrição. RESULTADOS: A normalidade dos dados coletados será confirmada pelo teste de Kolmogorov-Smirnov. A significância estatística intra e inter grupos será determinada por testes apropriados. O tamanho do efeito e a análise de potência serão realizados. CONCLUSÃO: Este estudo apresentará dados para a eficácia do VRT na melhora do equilíbrio e da marcha, além do PTP.
INTRODUCTION: Virtual reality (VR) intervention was found to be feasible in lower limb amputees (LLA). To best of our knowledge, only there is no randomized controlled trial available regarding the rehabilitation of LLA using VR. Evidence suggest that more researches for amputee rehabilitation using VR is warranted. OBJECTIVE: To compare the effectiveness of VR therapy as an additional therapeutic adjunct with physical therapy protocol on limits of stability and postural stability, pain and quality of life among LLA. METHODS: A total of 100 LLA will be recruited by the simple random sampling (random number generator) from JPN Apex Trauma Centre, AIIMS to participate in randomized controlled trial. Recruited LLA will be randomly divided into two groups, virtual reality therapy along with physical therapy protocol (VRT-PTP) group and physical therapy protocol (PTP) group. Duration of the treatment will be 30 minutes in one session/day for 4 days/week for 3 weeks. Thus, each LLA will receive 12 sessions in total. The Biodex Balance System for measuring dynamic balance, NPRS for pain and quality of life by WHO Quality of Life-BREF (WHOQOL-BREF) are the outcome measures will be recorded at baseline, end of 3-week post-intervention period. The follow-up will be taken at 6th and 9th week after enrollment. RESULTS: Normality of the collected data will be confirmed by Kolmogorov-Smirnov test. Statistical significance within and between the groups will be determined. Effect size and power analysis will be performed. CONCLUSION: This study will present data for the efficacy of the VRT in improving balance and gait in addition to PTP.

Introducción: Los pacientes que presentan una amputación a nivel transradial cuentan con oferta reducida de dispositivos protésicos (gancho y mano cosmética). Postulamos que disponer de nuevos sistemas protésicos 3D de bajo costo y la experiencia de su uso, permitirá aumentar las opciones para mejorar funcionalidad, actividad y participación. Objetivo: Evaluar el impacto funcional y psicosocial del uso de mano protésica manufacturada con impresión 3D. Método: Se seleccionó un paciente Teletón con amputación transradial de antebrazo izquierdo nivel tercio medio, 15 años de edad, con consentimiento informado. Se tomó molde en yeso y confeccionó prótesis 3D fabricada en acrilonitrilo butadieno estireno (ABS) y ácido poli-láctico (PLA); el pulgar tiene dos articulaciones y los demás dedos tres articulaciones. La prótesis la constituyen también el antebrazo y muñeca. El usuario recibió cuatro sesiones de entrenamiento con la prótesis en el lapso de un mes. Las evaluaciones con pauta de funcionalidad de mano Bilan 400 points modificada, índice funcional de las extremidades superiores (UEFI) y escala del impacto psicosocial de la asistencia tecnológica (PIADS), se aplicaron previo al ingreso, a tres y once meses de seguimiento. Resultados: La funcionalidad de mano mostró un incremento de alrededor de 30% con ambos instrumentos. En medición PIADS, competencia, autoestima y adaptabilidad, variaron de ningún efecto de la asistencia tecnológica, hasta el máximo de 3 puntos para adaptabilidad en el seguimiento a 11 meses. Conclusión: Este estudio de caso destaca potenciales beneficios del uso de prótesis de extremidad superior en el desempeño funcional y calidad de vida.
Introduction: The range of prosthetic devices (hooks and cosmetic hands) is limited for transradial amputation patients. Having new low-cost 3D prosthetic systems available, as well as experience on how to use them, will increase the options for better functionality, activity and participation. Objective: To assess functional and psychosocial impact of the use of 3D printed prosthetic hand. Method: A 15 year-old Teleton patient was selected with a middle third transradial amputation of the left forearm; informed consent was obtained. A plaster mold was taken and a 3D prosthesis was made using acrylonitrile butadiene styrene (ABS) and polylactic acid (PLA); the thumb had two articulations and the other fingers had three articulations. The prosthesis comprised also forearm and wrist. The user attended four prosthetic training sessions in a month. Modified Bilan 400 points scale for hand functionality, upper extremity functional index (UEFI) and the psychosocial impact of assistive devices scale (PIADS) were applied before admittance, and then at three and eleven months of follow up. Results: Hand functionality showed an increase of approximately 30% with both measuring instruments. In case of PIADS, competence, self-esteem and adaptability varied, from no effect of technology assistance, to the maximum of 3 points in adaptability at the eleven-month follow up. Conclusion: This case study highlights potential benefits of using upper limb 3D prosthesis on daily functional performance and quality of life.

Objetivo: Apresentar características do perfil de indivíduos amputados unilaterais na fase pré protética atendidos em um instituto de reabilitação hospitalar. Método: Estudo retrospectivo a partir dos registros dos prontuários dos pacientes amputados do Instituto de Medicina Física e Reabilitação da Universidade de São Paulo que realizaram reabilitação hospitalar na instituição. Foram analisados os prontuários de julho de 2015 até novembro de 2018. Nestes prontuários foram coletadas as informações sobre: idade, gênero, tipo de lesão, tempo da lesão, etiologia da lesão, mobilidade funcional por meio do teste Timed Up and Go (TUG), equilíbrio/funcionalidade por meio do teste Amputee Mobility Predictor (AMP), capacidade de caminhar por meio do teste de caminhada de 2 minutos (TC2Min). Análises descritivas foram feitas para avaliar as características demográficas e clínicas dos pacientes. Resultados: A média de idade foi de 43,59±16,52 anos, com tempo de amputação de 21,9±32,7 meses. Houve predominância do gênero masculino e a etiologia traumática e amputação transfemoral foram as mais prevalentes. Os dados clínicos encontrados foram: tempo de execução do teste TUG: 18,7 segundos, da AMP: 31,2 pontos, TC2Min: 111,2 metros. Conclusão: Na fase pré-protética, a origem traumática foi predominante, sendo a maioria do gênero masculino. A amputação transfemoral foi superior às demais. O tempo médio da amputação até a internação é quase de dois anos. Os testes clínicos embora apresentem bons resultados, mostram a necessidade de serem aprimoradas as questões como, por exemplo, a mobilidade funcional que é condizente com risco de quedas nestes indivíduos.

Artificial prosthesis is an important tool to help amputees to gain or partially obtain abled human limb functions. Compared with traditional prosthesis which is only for decoration or merely has feedforward control channel, the perception and feedback function of prosthesis is an important guarantee for its normal use and self-safety. And this includes the information of position, force, texture, roughness, temperature and so on. This paper mainly summarizes the development and current status of artificial prostheses in the field of perception and feedback technology in recent years, which is derived from two aspects: the recognition way of perception signals and the feedback way of perception signals. Among the part of recognition way of perception signals, the current commonly adopted sensors related to perception information acquisition and their application status in prosthesis are overviewed. Additionally, from the aspects of force feedback stimulation, invasive/non-invasive electrical stimulation, and vibration stimulation, the feedback methods of perception signals are summarized and analyzed. Finally, some problems existing in the perception and feedback technology of artificial prosthesis are proposed, and their development trends are also prospected.

Myoelectric prosthesis requires a sensor that can reliably capture surface electromyography (sEMG) signal from amputees for its controlled operation. The main problems with the presently available EMG devices are their extremely high cost, large response time, noise susceptibility, less amplitude sensitivity, and larger size. This paper proposes a compact and affordable EMG sensor for the prosthetic application. The sensor consists of an electrode interface, signal conditioning unit, and power supply unit all encased in a single package. The performance of dry electrodes employed in the skin interface was compared with the conventional Ag/AgCl electrodes, and the results were found satisfactory. The envelope detection technique in the sensor based on the tuned RC parameters enables the generation of smooth, faster, and repeatable EMG envelope irrespective of signal strength and subject variability. The output performance of the developed sensor was compared with commercial EMG sensor regarding signal-to-noise ratio, sensitivity, and response time. To perform this, EMG data with both devices were recorded for 10 subjects (3 amputees and 7 healthy subjects). The results showed 1.4 times greater SNR values and 45% higher sensitivity of the developed sensor than the commercial EMG sensor. Also, the proposed sensor was 57% faster than the commercial sensor in producing the output response. The sEMG sensor was further tested on amputees to control the operation of a self-designed 3D printed prosthetic hand. With proportional control scheme, the myoelectric hand setup was able to provide quicker and delicate grasping of objects as per the strength of the EMG signal.

BACKGROUND: Prosthetic hands with a myoelectric interface have recently received interest within the broader category of hand prostheses, but their high cost is a major barrier to use. Modern three-dimensional (3D) printing technology has enabled more widespread development and cost-effectiveness in the field of prostheses. The objective of the present study was to evaluate the clinical impact of a low-cost 3D-printed myoelectric-interface prosthetic hand on patients' daily life. METHODS: A prospective review of all upper-arm transradial amputation amputees who used 3D-printed myoelectric interface prostheses (Mark V) between January 2016 and August 2017 was conducted. The functional outcomes of prosthesis usage over a 3-month follow-up period were measured using a validated method (Orthotics Prosthetics User Survey–Upper Extremity Functional Status [OPUS-UEFS]). In addition, the correlation between the length of the amputated radius and changes in OPUS-UEFS scores was analyzed. RESULTS: Ten patients were included in the study. After use of the 3D-printed myoelectric single electromyography channel prosthesis for 3 months, the average OPUS-UEFS score significantly increased from 45.50 to 60.10. The Spearman correlation coefficient (r) of the correlation between radius length and OPUS-UEFS at the 3rd month of prosthetic use was 0.815. CONCLUSIONS: This low-cost 3D-printed myoelectric-interface prosthetic hand with a single reliable myoelectrical signal shows the potential to positively impact amputees' quality of life through daily usage. The emergence of a low-cost 3D-printed myoelectric prosthesis could lead to new market trends, with such a device gaining popularity via reduced production costs and increased market demand.

OBJECTIVE: To study factors associated to the quality of life in a North African sample of lower limbs amputees. METHODS: We conducted a prospective study in the Department Physical Medicine and Rehabilitation, University Hospital of Monastit, Tunisia. A consecutive sample of patients with amputations of the lower limbs was included. The evaluated parameters were quality of life using the Short-Form quality-of-life questionnaire (SF-36), pain using a visual analog scale, function using, the perimeter of walking (PW), the Special Interest Group of the Amputee Medicine (SIGAM) and the Locomotion Capacities Index of the Prosthetic Profile of the Amputee (LCI), and psychological status thanks to the Hospital Anxiety and Depression scale. In the study, the patients were evaluated at the first consultation (T0) and again at 12 months (T1). RESULTS: We included 85 patients (age, 59.3±16.7 years) with a sex ratio of 3. The patient quality of life was positively correlated to distal type of amputation, traumatic origin, better LCI (p≤0.001, r=0.349), SIGAM (p=0.046) and PW. A negative correlation was noted with age (p=0.012, r=−0.483) and higher psychological scores (p=0.002, r=−0.321). CONCLUSION: In our sample of North African lower limbs amputees the age and the functional status were the most important predictors of the quality of life.

INTRODUCTION: Amputation is often associated with depression, isolation and anxiety, resulting in changesin the functioning and quality of life of an individual. This study aimed to compare the quality of life ofamputees before and after prosthetic rehabilitation and to determine the level of satisfaction with theservices provided by the rehabilitation team.METHODS: This was a longitudinal study conducted at the Philippine School of Prosthetics and Orthoticsfrom 2016 to 2017. Quality of life was measured at baseline and at the end of prosthetic rehabilitationusing the Short Form-36 version 2 Philippines (Tagalog) and compared. Patient satisfaction was determinedusing the UERMMMCI Out-Patient Satisfaction Survey. Statistical analysis was done using paired t-testand stratified analysis.RESULTS: Twelve participants were included; majority were adult males and all were unemployed. Therewere no statistically significant changes in the quality of life of amputees after prosthetic rehabilitation.Stratification analysis revealed significant decreases in scores in bodily pain and general health scales forfemales. On the other hand, males had statistically significant increases in vitality scores. Participantswere generally satisfied with the services they received.CONCLUSION: While no significant changes were observed for overall quality of life, certain aspects may berelated to factors such as sex, comorbidities, and type of caregiver. Recommendations include further studiesto explore other factors affecting quality of life among Filipino amputees after prosthetic rehabilitation.

OBJETIVOS: Avaliar a postura de sujeitos com amputação de membro inferior. MÉTODOS: Participaram do presente estudo 10 sujeitos do sexo masculino, com 38,2±8,2 anos, com amputação em diferentes níveis de membro inferior, unilateral, protetizados. Para a avaliação postural foi utilizado o Software de Avaliação Postural (SAPO), sendo as imagens avaliadas de acordo com o protocolo do software. Os dados foram analisados através da estatística descritiva e inferencial (teste t independente), com valor de significância de p≤0,05. RESULTADOS: As principais alterações observadas foram: retropé com um valgo aumentado, tornozelo fletido, cabeça inclinada para a direita e tronco em flexão. Quando comparada a postura de acordo com o tempo de amputação, se observou diferença estatisticamente significativa na assimetria horizontal da escápula em relação à T3 (p=0,004), sendo que sujeitos com tempo de amputação de até seis anos apresentaram a escápula esquerda mais alta que a direita (-5,28±8,16°) e os com mais de seis anos de amputação apresentaram a escápula direita mais alta que esquerda (19,42±11°). Na comparação entre níveis de amputação, se observou diferença estatisticamente significativa no ângulo do tornozelo (p=0,008), com os sujeitos com amputação abaixo do joelho apresentando maior flexão do tornozelo (81,97±1,72°) do que os com amputação ao nível do joelho e acima deste (87,30±2,65°). CONCLUSÕES: Os achados do presente estudo demonstram que todos os sujeitos avaliados apresentaram alguma alteração postural, porém, não se pode afirmar que a assimetria postural destes é devido à amputação.
AIMS: To evaluate the posture of subjects with lower limb amputee. METHODS: Ten subjects participated in the study, males, with 38,2±8,2 years, with unilateral lower limb amputation and prosthesis users. For the postural evaluation, the Postural Evaluation Software (SAPO) was used, and the images were evaluated according to the software protocol. Data were analyzed through descriptive and inferential statistics (independent t test), with a significance level of p≤0,05. RESULTS: The main alterations observed were: rearfoot valgus enlargement, flexed ankle, head tilted to the right and trunk in flexion. When compared the posture according to time of amputation, was observed a statistically significant difference in the horizontal asymmetry of scapula in relation to T3 (p=0,004), being that subjects with amputation time of up to six years presented the left scapula higher than the right one (-5,28±8,16°) and those with more than six years of amputation had the right upper right scapula (19,42±11°). In the comparison between amputation levels, there was a statistically significant difference in the ankle angle (p=0,008), with subjects with amputation below the knee presenting greater ankle flexion (81,97±1,72°) than those with amputation at the level of the knee and above this (87,30±2,65°). CONCLUSIONS: The findings of the present study demonstrate that all the evaluated subjects presented some postural alteration, however, it cannot be affirmed that the postural asymmetry of these is due to the amputation.

OBJETIVOS: Avaliar a satisfação e o ajuste à prótese de indivíduos com amputação de membro inferior. MÉTODOS: Participaram 24 indivíduos com amputação de membro inferior com 46,1±17,5 anos e que utilizam prótese há 10,8±8,7 anos. Foi utilizada uma ficha para caracterização dos indivíduos e o questionário Prosthesis Evaluation Questionnaire (PEQ) para avaliar a satisfação e o ajuste à prótese. Os dados foram coletados em instituições que atendem pessoas amputadas nos estados do Rio Grande do Sul e Santa Catarina e analisados pela estatística descritiva e inferencial com nível de significância de 5%. RESULTADOS: Não houve diferença significativa nos resultados do PEQ entre os indivíduos quando comparados em relação ao nível de amputação e ao tempo que utilizam a prótese. Em relação aos escores obtidos entre os grupos com amputação vascular e traumática, houve diferença significativa na subescala de saúde do membro residual, com maiores escores e consequente melhor saúde do membro residual nos indivíduos com amputação de causa vascular, além de melhores escores na escala de satisfação nestes indivíduos. CONCLUSÕES: Foi possível concluir que indivíduos com amputação de causa vascular são mais satisfeitos com sua prótese, com a maneira como andam e como as coisas estão desde a amputação e também possuem melhor saúde do membro residual em relação a indivíduos com amputação traumática. Porém, o nível e o tempo de amputação parecem não influenciar na satisfação e no ajuste à prótese.
AIMS: Evaluate satisfaction and adjustment to the prosthesis of individuals with lower limb amputation. METHODS: Participants were 24 patients with lower limb amputation with 46,1±17,5 years and using the prosthesis for 10,8±8,7 years. A card was used to characterize the individuals and the Prosthesis Evaluation Questionnaire (PEQ) to evaluate satisfaction and adjustment to the prosthesis. Data were collected from institutions that serving amputees in the states of Rio Grande do Sul and Santa Catarina and analyzed by descriptive and inferential statistics at a 5% significance level. RESULTS: There was no significant difference in the results of the PEQ between individuals when compared to the level of amputation and time using the prosthesis. Regarding the scores between groups with vascular and traumatic amputation, was a significant difference in residual limb health subscale, with higher scores and consequently better health of the residual limb in amputees with vascular causes, besides better higher scores on the scale of satisfaction in these individuals. CONCLUSIONS: It was concluded that patients with a vascular cause of amputation are more satisfied with their prosthesis, with the way they walk and how things are from amputation and also have better health of the residual limb in relation to individuals with traumatic amputation. However, the level and time of amputation do not seem to influence the satisfaction and adjustment of the prosthesis.
