Adaptation transculturelle et validation du questionnaire Upper Limb Functional Index (ULFI) pour la population canadienne française

Hamasaki, Tokiko 12 1900 (has links)
Les troubles musculo-squelettiques du membre supérieur (TMS-MS) peuvent avoir un impact négatif sur l'autonomie d’une personne. À ce jour, il n’existe pas d’outils en français évaluant les limitations d'activités et les restrictions de participation, disposant de bonnes propriétés métrologiques et d'applicabilité dans un contexte clinique marqué par des contraintes de temps. L’Upper Limb Functional Index (ULFI), qui présente de bonnes qualités métrologiques et applicabilité clinique adéquate, s'avère un outil intéressant pour les ergothérapeutes de par son approche centrée sur la personne. Toutefois, il n'était disponible qu'en anglais et en espagnol. La présente recherche, constituée de deux études, visait à adapter l’ULFI à la population canadienne française et à évaluer ses propriétés métrologiques et son applicabilité clinique. La première étude a examiné sa cohérence interne, sa validité convergente et son applicabilité clinique auprès de 50 patients bilingues atteints de TMS-MS. La seconde étude visait à analyser sa fidélité test-retest et sa sensibilité au changement auprès de 60 patients francophones. Les résultats ont révélé que l'ULFI-CF possède des propriétés métrologiques solides : une cohérence interne élevée (α de Cronbach = 0,93), une excellente fidélité test-retest (CCI = 0,87-0,95), une excellente validité convergente (r = 0,70-0,85) et une sensibilité au changement de bonne à excellente (tailles d'effet = 0,49-0,88 et r = 0,64 pour la section 1). L'ULFI-CF démontre également une bonne applicabilité clinique. En conclusion, l’ULFI-CF s’avère un outil pertinent pour les cliniciens œuvrant auprès d’une clientèle canadienne française souffrant d'un TMS-MS dans un contexte clinique marqué par des contraintes de temps. / Upper limb musculoskeletal disorders (UL-MSD) can negatively impact on patients' autonomy. There are no existing outcome measures available in French to assess activity limitations and participation restrictions caused by UL-MSD that have sound metrological properties and are applicable in a clinical context where clinicians have limited assessment time for each patient. The Upper Limb Functional Index (ULFI), having good metrological qualities and clinical applicability, is a relevant tool for clinicians since it promotes a patient-centered approach. However, the tool was only available in English and Spanish until now. This research project included two studies and aimed at adapting the ULFI to the French Canadian population and to assess the metrological properties of the adapted version (ULFI-FC) and its clinical applicability. The first study examined its internal consistency, convergent validity and clinical applicability among 50 bilingual patients with UL-MSD. The second study aimed to analyse its test-retest reliability and responsiveness among 60 French-speaking patients. The findings revealed that the ULFI-FC possesses sound metrological properties: a high internal consistency (Cronbach α = 0.93 for Part 1), an excellent test-retest reliability (ICC = 0.87-0.95), an excellent convergent validity (r = 0.70-0.85), and good to excellent responsiveness (effect size = 0.49-0.88; and r = 0.64 for Part 1), as well as good clinical applicability in a context where assessment time devoted to each patient is limited. In conclusion, the ULFI-CF is a relevant and attractive tool assessing activity limitations and participation restrictions for clinicians working with French Canadian UL-MSD patients in a busy clinical setting.

Avaliação da eletroestimulação com biofeedback por eletromiografia de superfície em pacientes hemiplégicos / Evaluation of electrical stimulation with surface electromyographic biofeedback of hemiplegic patients

Lourenção, Maria Inês Paes 07 March 2007 (has links)
O objetivo deste estudo foi avaliar o efeito do biofeedback (BIO) associado à terapia ocupacional (TO) e à estimulação elétrica funcional (FES) na espasticidade, movimento ativo e função do membro superior de pacientes hemiplégicos. Este estudo foi realizado na Divisão de Medicina de Reabilitação do Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo. Cinqüenta e nove pacientes acometidos por acidente vascular cerebral participaram do estudo por um ano; 31 receberam TO+FES duas vezes por semana + BIO uma vez por semana e 28 receberam somente TO+FES duas vezes por semana. Os pacientes foram avaliados inicialmente, após 6 meses e após 1 ano através da Avaliação da Função Manual, do Teste de Destreza Manual Minnesota, do Teste de Amplitude de Movimento e da Escala de Ashworth modificada. TO+FES+BIO melhoraram significativamente a amplitude de movimento e função dos membros superiores após 6 meses e 12 meses, quando comparado com somente TO+FES. Ambos os grupos melhoraram significativamente a espasticidade, após 6 meses e 12 meses, com diferença não significante entre eles. O uso adicional do biofeedback mostrou efeito positivo em amplitude de movimento e recuperação da função do membro superior no grupo estudado e pode representar uma importante ferramenta para a reabiltação de pacientes hemiplégicos / The objective of this was to study the effect of biofeedback (BIO) associated to occupational therapy (OT) and functional electrical stimulation (FES) on spasticity, range of motion and upper extremity function of hemiplegic patients. The study took part at the Division of Rehabilitation Medicine of the Hospital das Clínicas of the University of São Paulo School of Medicine. Fifty-nine stroke patients were studied for one year; 31 received OT+FES twice a week + BIO once-a-week and 28 received only OT+FES twice-aweek. The patients were evaluated initially, after six months and after one year with the use of Manual Function Evaluation, Minnesota Manual Dexterity Test, Range of Joint Motion Test and Modified Ashworth Scale. OT+FES+BIO significantly improved range of motion and upper extremity function after 6 months and 12 months, compared to only OT+FES. Both groups showed significant improvement of spasticity, after 6 months and 12 months, with no significant difference between them. The additional use of BIO had a positive effect in range of motion and function recovery of upper extremity in the studied group and may represent an important therapeutic tool for stroke rehabilitation

"Avaliação objetiva da isquemia de membros superiores: uso do dinamômetro isocinético" / Objective evaluation of upper limbs ischemia: use of isokinetic dynamometer

Nakano, Livio 13 September 2005 (has links)
O objetivo deste trabalho é apresentar o teste de esforço com o dinamômetro isocinético na avaliação objetiva da isquemia funcional da doença arterial oclusiva de membros superiores (DAOMS). Reuniu-se 23 pacientes com DAOMS unilateral, no grupo 1. Sete pacientes, sem DAOMS foram selecionados como o grupo controle (grupo 2). Os membros testados sem DAOMS do grupo 1 e do grupo 2 não apresentaram diferença estatística. A comparação de cada membro dos pacientes do grupo 1, com e sem DAOMS mostrou que os membros com DAOMS apresentaram desempenho significativamente menor que os membros sem lesão. Este teste permite a avaliação objetiva da limitação causada pela DAOMS de forma segura e objetiva / The objective of this work is to present the results of a stress test using an isokinetic dynamometer in patients with occlusive arterial disease in upper limbs (OADUL). Group 1 has 23 patients with unilateral subclavian occlusive disease. Seven patients, without OADUL, were included in a control group (group 2). No statistically difference was found in all parameters studied between limbs without OADUL in groups 1 and 2. So, each arm in group 1 (with and without OADUL) were tested. For all these parameters, the SOD limbs presented significantly lower values than the control limbs. This test gives an objective grade of limitation of the muscle function in patients with OADUL

Estudo experimental de avulsão parcial de retalho cutâneo em membros inferiores de ratos / Experimental study of partial avulsion of skin flaps in hind limbs of rats

Dimas Andre Milcheski 18 February 2011 (has links)
INTRODUÇÃO: Os desenluvamentos cutâneos são lesões graves e frequentemente há dificuldade para o cirurgião decidir qual o tratamento mais adequado a ser instituído, o reposicionamento e sutura do retalho ou o desengorduramento do retalho e enxertia da pele avulsionada. A conduta cirúrgica de reposicionamento e sutura do retalho é mais rápida e simples de ser realizada, mantém as características anatômicas e fisiológicas locais, mas frequentemente evolui com perda parcial ou total do retalho avulsionado. O tratamento cirúrgico de adelgaçamento do retalho desenluvado e enxertia da pele obtida tem a desvantagem de resultar em aspecto estético e protetivo inferiores, mas é o tratamento mais utilizado devido à maior taxa de integração do enxerto. Medicações com propriedades de aumentar a perfusão do retalho desenluvado podem permitir a conduta cirúrgica de reposicionamento e sutura do retalho ao seu leito original, mantendo as vantagens da cobertura cutânea original e preservando total ou parcialmente a viabilidade do retalho. Este estudo avaliou o efeito dos fármacos enoxaparina, pentoxifilina e alopurinol na diminuição da área de necrose de retalhos cutâneos avulsionados através da utilização de um modelo experimental de desenluvamento cutâneo em membros inferiores de ratos. MÉTODOS: Os animais foram divididos em 4 grupos com 25 ratos em cada um deles. Os quatro grupos foram submetidos ao modelo proposto de desenluvamento de todo membro inferior, resultando em um retalho de fluxo distal que foi reposicionado ao leito e suturado. O grupo 1 (avulsão / controle) recebeu 1ml de solução salina via intraperitoneal. O grupo 2 (avulsão / enoxaparina) recebeu 1 ml de enoxaparina (320 UI/kg) via subcutânea. O grupo 3 (avulsão / pentoxifilina) recebeu 1 ml de pentoxifilina (25 mg/kg) via intraperitoneal. O grupo 4 (avulsão / alopurinol) recebeu 1 ml de alopurinol (45 mg/kg) via intraperitoneal. As medicações foram infundidas em dose única imediatamente após o reposicionamento e sutura do retalho avulsionado. Os animais foram observados até o 7° dia pós-operatório, quando foram sacrificados e o retalho desenluvado foi retirado e analisado. A área total do retalho e a área de necrose do retalho foram quantificadas para todos os animais e análise estatística foi realizada entre os grupos. RESULTADOS: a mediana da área total do retalho desenluvado (cm2) foi de 5,633 para G1, 5,353 para G2, 5,505 para G3 e de 5,870 para G4 (p = 0,7460). A mediana da área de necrose do retalho desenluvado (cm2) foi de 3,368 para G1, 1,663 para G2, 2,297 para G3 e de 1,888 para G4 (p < 0,0001). Houve diferença estatística entre os pares G1 e G2, G1 e G3, G1 e G4 (p < 0,05). A relação entre a área de necrose e área total do retalho desenluvado para os quatro grupos foi de 63,34% (G1), 32,71% (G2), 41,7% (G3) e 34,85% (G4) (p < 0,0001). Houve diferença estatística entre os pares G1 e G2, G1 e G3, G1 e G4 (p < 0,05). CONCLUSÕES: Houve diminuição da área de necrose em retalhos cutâneos avulsionados em membros inferiores de ratos com a utilização das medicações enoxaparina (G2), pentoxifilina (G3) e alopurinol (G4) quando comparados ao grupo controle (G1). Não houve diferença estatística significativa entre os grupos terapêuticos com relação à área de necrose nos retalhos cutâneos avulsionados (G2 x G3; G2 x G4; G3 x G4) / INTRODUCTION: Degloving injuries may be a challenge when it comes to deciding the surgical approach to be used. Repositioning of the flap and suturing is faster and more straightforward, but often leads to total or partial loss of the avulsed flap. Skin flap deffating and grafting of the detached flap have the disadvantages of resulting in poor aesthetic appearance and being less protective, but they have been the most widely used due to the higher rate of graft take. Pharmacological agents with vascular properties that enhance the viability of the reattached flap could be beneficial to patients with degloving injuries. This study evaluated the effects of enoxaparin, pentoxifylline and allopurinol in reducing necrosis area of avulsed skin flaps through a degloving experimental model in the hind limb of rats. METHODS: Rats were grouped in four groups with 25 rats each. The four groups were subjected to the proposed degloving model of hind limb, resulting in a reverse flow flap. The flap was then repositioned and sutured. Group 1 (avulsion / control) received 1 ml saline solution intraperitoneally. Group 2 (avulsion / enoxaparin) received 1 ml of enoxaparin (320 IU/kg) subcutaneously. Group 3 (avulsion / pentoxifylline) received 1 ml of pentoxifylline (25 mg/kg) intraperitoneally. Group 4 (avulsion / allopurinol) received 1 ml of allopurinol (45 mg/kg) intraperitoneally. Saline solution and medications were infused in single dose after wound closure. The animals were observed until 7 days postoperatively, when they were sacrificed and the degloved flap was removed and analyzed by image processing software. The total area of the avulsed flap and the necrotic area were measured for all animals and statistical analysis was performed between groups. RESULTS: The median total flap area (cm2) was 5.633 for G1, 5.353 for G2, 5.505 for G3 and 5.870 for G4 (p = 0.7460). The median necrotic flap area (cm2) was 3.368 for G1, 1.663 for G2, 2.297 for G3 and 1.888 for G4 (p < 0.0001). There was statistical difference between pairs G1 and G2, G1 and G3, G1 and G4 (p < 0.05). The ratio between the necrotic flap area and total flap area was 63.34% (G1), 32.71% (G2), 41.7% (G3) and 34.85% (G4) (p < 0.0001). There was statistical difference between pairs G1 and G2, G1 and G3, G1 and G4 (p < 0.05). CONCLUSIONS: There was a decrease in necrosis of the avulsed skin flap in the hind limbs of rats with the use of medications enoxaparin (G2), pentoxifylline (G3) and allopurinol (G4) compared to the control group (G1). There was no statistically significant difference in the necrosis area of avulsed skin flaps between treatment groups (G2 x G3; G2 x G4; G3 x G4)
