RESUMO
ABSTRACT. Action observation (AO) has been proved to be of benefit in several neurological conditions, but no study has previously been conducted in idiopathic normal pressure hydrocephalus (iNPH). Objective: This study aimed to investigate the feasibility of AO in iNPH patients. Methods: A single-group pretest-posttest design was conducted in twenty-seven iNPH patients. Gait and mobility parameters were assessed using the 2D gait measurement in the timed up and go (TUG) test for two trials before and after immediate AO training. The outcomes included step length and time, stride length and time, cadence, gait speed, sit-to-stand time, 3-m walking time, turning time and step, and TUG. In addition, early step length and time were measured. AO consisted of 7.5 min of watching gait videos demonstrated by a healthy older person. Parameters were measured twice for the baseline to determine reproducibility using the intraclass correlation coefficient (ICC3,1). Data between before and after immediately applying AO were compared using the paired t-test. Results: All outcomes showed moderate to excellent test-retest reliability (ICC3,1=0.51 0.99, p<0.05), except for the step time (ICC3,1=0.19, p=0.302), which showed poor reliability. There were significant improvements (p<0.05) in step time, early step time, gait speed, sit-to-stand time, and turning time after applying AO. Yet, the rest of the outcomes showed no significant change. Conclusions: A single session of AO is feasible to provide benefits for gait and mobility parameters. Therapists may modify this method in the training program to improve gait and mobility performances for iNPH patients.
RESUMO. A observação de ação (OA) teve benefícios comprovados em diversas condições neurológicas, mas nenhum estudo foi conduzido anteriormente em Hidrocefalia de Pressão Normal idiopática (HPNi). Objetivo: O presente estudo teve como objetivo investigar a viabilidade da OA em pacientes com HPNi. Métodos: Um projeto de pré-teste e pós-teste de grupo único foi realizado em 27 pacientes com HPNi. Parâmetros de marcha e mobilidade foram avaliados por meio de parâmetros 2D para a medida da marcha com o teste timed up and go (TUG) com duas tentativas antes e imediatamente depois do OA. Os resultados incluíram comprimento e tempo do passo, comprimento e tempo da passada, cadência, velocidade da marcha, tempo para sentar-e-levantar, tempo de caminhada de 3 metros, tempo de virada e passo, e tempo do teste (TUG). Além disso, o comprimento do passo inicial e o tempo da etapa inicial foram medidos. A OA consistia em assistir 7,5 minutos de vídeos de marcha demonstrados por um idoso saudável. Os parâmetros foram medidos duas vezes para a linha de base para determinar a reprodutibilidade usando o coeficiente de correlação intraclasse (CCI3,1). Os dados entre antes e depois da aplicação imediata de OA foram comparados com o teste t pareado. Resultados: Todos os resultados mostraram confiabilidade teste-reteste moderada a excelente (CCI3,1=0,51 0,99, p<0,05), exceto para o tempo do passo (CCI3,1=0,19, p=0,302), que apresentou confiabilidade pobre. Houve melhorias significativas (p<0,05) no tempo do passo, tempo do passo inicial, velocidade da marcha, tempo sentar-e-levantar e tempo de virar após a aplicação de OA. Os demais resultados não mostraram nenhuma mudança significativa. Conclusões: Uma única sessão de aplicação de OA é viável para proporcionar benefícios aos parâmetros de marcha e mobilidade. Os terapeutas podem modificar esse método no programa de treinamento para obter desempenho de marcha e mobilidade para pacientes com HPNi.

Objective: To present the results of our treatment of indirect carotid- cavernous sinus fistulas with surgical exposure of the superior ophthalmic vein (SOV), retrograde venous catheterization, and coil embolization of the cavernous sinus in a patient whom the standard transvenous catherization for treatment of indirect carotid–cavernous fistulas had failed. Methods: No method Results: Complete fistula obliteration was accompanied by recovery of the clinical symptoms. Conclusion: The surgical SOV approach might be sufficient when standard endovascular intervention does not succeed. The technique is safe and effective when performed by an interdisciplinary team.
RESUMO
Objective: To review Siriraj Hospital’s experiences with direct surgical treatment of complicated traumatic carotid-cavernous fistulas (CCFs) in the context of multidisciplinary approach. Methods: This study is a retrospective review of complicated direct carotid cavernous fistulas (CCFs) that had opened surgery after failure of detachable balloon embolization. Data were collected from medical records, radio-angiographic records, and follow-up results of combinations of treatment. Results: From 1993- April 2003, we have total 25 cases of combined surgery and endovascular treatment of traumatic carotid-cavernous fistulas (CCFs). Causes of unsuccessful balloon embolization are small-hole fistula, deflation of the balloon, difficult position of fistula, false aneurysm, risk of intracavernous internal carotid artery (ICA) occlusion, and tortuosity of ICA and draining veins. Various procedures were performed and all patients have good results with completed resolution of clinical triad symptoms. On follow-up cerebral angiography of 16 patients that received cavernous sinus packing, we could preserve the patency of ICA in 8 patients but 5 patients had thrombosis of ICA without ischemic events. In 3 patients, an operation to occlude the ICA was performed after failure of cavernus sinus packing. Conclusions: The standard treatment of carotid cavernous fistula is endovascular balloon embolization. When the endovascular treatment fails, surgical packing of cavernous sinus is immediately considered an alternative way to cure the CCFs and to offer additional technique to help increase the patency of ICA.
