Objectives: To compare optical values in the osteotomy gap created after a Tibial Tuberosity Advancement (TTA) treated with autogenous cancellous bone graft (ACBG), extracorporeal shock wave therapy (ESWT), a combination of ACBG and ESWT, and absence of both ACBG and ESWT using densitometry. Methods: Dogs presenting for surgical repair of a cranial cruciate ligament rupture were randomly assigned to one of four groups; TTA with ACBG (TTA-G), TTA with ACBG and ESWT (TTA-GS), TTA with ESWT (TTA-S), and TTA with no additional therapy (TTA-O). Mediolateral radiographs at 0, 4 and 8 weeks after surgery were evaluated to compare healing of the osteotomy gap via densitometry. An analysis of variance (ANOVA) statistical analysis was used to compare the densitometric values between groups. Results: At 4 weeks after surgery, a significant difference in osteotomy gap density was noted between TTA-GS (8.4 millimeters of Aluminum equivalent [mmAleq]) and TTA-S (6.1mmAleq), and between TTA-GS (8.4 mmAleq) and TTA-O (6.4 mmAleq). There were no significant differences noted between groups at the 8 week recheck. Clinical Significance: There were no significant differences in the osteotomy gap density at 8 weeks after surgery regardless of the treatment modality used. The combination of ACBG and ESWT may lead to increased density of the osteotomy gap in the first 4 weeks after surgery. Densitometry using an aluminum step wedge is a feasible method for comparison of bone healing after TTA in dogs. / Master of Science

Yes / Background Walking down slopes and/or over uneven terrain is problematic for unilateral trans-tibial amputees. Accordingly, ‘ankle’ devices have been added to some dynamic-response feet. This study determined whether use of a microprocessor controlled passive-articulating hydraulic ankle–foot device improved the gait biomechanics of ramp descent in comparison to conventional ankle–foot mechanisms. Methods Nine active unilateral trans-tibial amputees repeatedly walked down a 5° ramp, using a hydraulic ankle–foot with microprocessor active or inactive or using a comparable foot with rubber ball-joint (elastic) ‘ankle’ device. When inactive the hydraulic unit's resistances were those deemed to be optimum for level-ground walking, and when active, the plantar- and dorsi-flexion resistances switched to a ramp-descent mode. Residual limb kinematics, joints moments/powers and prosthetic foot power absorption/return were compared across ankle types using ANOVA. Findings Foot-flat was attained fastest with the elastic foot and second fastest with the active hydraulic foot (P < 0.001). Prosthetic shank single-support mean rotation velocity (p = 0.006), and the flexion (P < 0.001) and negative work done at the residual knee (P = 0.08) were reduced, and negative work done by the ankle–foot increased (P < 0.001) when using the active hydraulic compared to the other two ankle types. Interpretation The greater negative ‘ankle’ work done when using the active hydraulic compared to other two ankle types, explains why there was a corresponding reduction in flexion and negative work at the residual knee. These findings suggest that use of a microprocessor controlled hydraulic foot will reduce the biomechanical compensations used to walk down slopes.

The aim of this thesis was to determine the biomechanical adaptations made by active unilateral trans-tibial amputees when they used a prosthesis incorporating a hydraulically-damped, articulating ankle-foot device compared to non-hydraulically attached devices. Kinematic and kinetic data were recorded while participants ambulated over a flat and level surface at their customary walking speeds and at speeds they perceived to be faster and slower using the hydraulic device and their habitual foot. Use of the hydraulic device resulted in increases in self-selected walking speeds with a simultaneous reduction in intact-limb work per meter travelled. Use of the device also attenuated inappropriate fluctuations in the centre-of-pressure trajectory beneath the prosthetic foot and facilitated increased residual-knee loading-response flexion and prosthetic-limb load bearing during stance. These changes occurred despite the hydraulic device absorbing more, and returning less, energy than the participants’ habitual ankle-foot devices. The changes were present across all walking speeds but were greatest at customary walking speeds. The findings suggest that a hydraulic ankle-foot device has mechanical benefits, during overground gait, for active unilateral trans-tibial amputees compared to other attachment methods. The findings also highlight that prosthetic ankle-foot device ‘performance’ can be evaluated using surrogate measures and without modelling an ‘ankle joint’ on the prosthetic limb.

La stimulation corticomotoneuronale pairée (PCMS) combine stimulation magnétique transcrânienne (TMS) du cortex moteur primaire (M1) et stimulation électrique périphérique (ePCMS). L'intervalle synchronisant l'arrivée des potentiels d'action pré- et post-synaptique au niveau de la synapse corticomotoneuronale vise l'induction d'une plasticité spinale de type potentialisation long terme. Le pairage avec la stimulation périphérique magnétique (mPCMS) pourrait être plus efficace pour augmenter l'excitabilité corticospinale vu la correspondance d'activation des motoneurones avec la TMS et les afférences purement proprioceptives. La mPCMS a été comparée avec la ePCMS pour tester les effets induits (mesurés par l'amplitude des potentiels évoqués moteurs (MEP)) appliqués au membre inférieur durant une activation volontaire. L'influence des variants du gène BDNF (brain-derived neurotrophic factor) sur la réponse aux PCMS a également été observée. Seize adultes en santé ont participé à deux expérimentations pairant la TMS de M1 du tibial antérieur (TA) avec la stimulation du nerf fibulaire commun (aux intensités sous le seuil de la douleur) à l'intervalle inter-stimuli personnalisé, pendant une légère contraction isométrique du TA. En somme, la majorité des participants ont eu une augmentation significative de l'amplitude des MEP. La grandeur de la taille effet était différente entre les protocoles et dans le temps soit: un changement plus marqué direction après l'intervention ePCMS (taille d'effet moyen) et 30 minutes après l'intervention mPCMS (effet très large). Les variables secondaires n'ont pas été influencées, supportant l'origine prémotoneuronale de l'augmentation d'excitabilité corticospinale. Une distribution différente des génotypes du BDNF a été notée: les répondants en ePCMS étaient davantage porteurs du génotype Val66Val et ceux en mPCMS étaient plus des porteurs de l'allèle Met. Il s'agit de la première étude testant les mPCMS et appliquant les ePCMS en activité au membre inférieur et nos conclusions supportent leur efficacité et pertinence. Davantage d'études au design expérimental sont nécessaires pour reproduire nos résultats et explorer le potentiel des mPCMS. / Paired corticomotoneuronal stimulations (PCMS) is of great interest as a novel neurostimulation paradigm to explore the potential plasticity of the spinal cord. The methods consist in the synchronization of presynaptic (from transcranial magnetic stimulation (TMS) at the primary motor cortex) and postsynaptic (from peripheral stimulation of the nerve) volleys at the corticomotoneuronal synapse to induce STDP-like (spike-timing-dependant-plasticity) after-effects. The body of PCMS literature has investigated its application at the upper limb with only few at the lower limb. The peripheral nerve stimulation is usually electrical (ePCMS) and pairing TMS with magnetic stimulation of the nerve (mPCMS) has never been tested. This new paradigm would have interesting advantages compared to ePCMS: recruits first alpha-motoneurons of small diameters (correspondence with activated motoneuron by TMS) and generates almost pure proprioceptive afferences. After-effects on corticospinal excitability (measured by motor evoked potential (MEP) amplitude) were compared between the two PCMS protocols (ePCMS vs. mPCMS) at the tibial anterior (TA: ankle dorsiflexor) in active state for healthy participants. Our findings have shown that both ePCMS and mPCMS are effective to strengthen corticospinal projections in painless intensities at the TA in active state for a majority of healthy participants. For the first time studied, mPCMS has shown promising results for inducing LTP-like effects as its magnitude of effect was considered very large (for responders in Post30) compared to medium-sized effect for ePCMS (in Post0). The factor BDNF genotypes was also observed in our study, revealing different distribution between the two protocols: Val66Vall genotype was predominant in ePCMS responders, while Met allele carriers were more represent in mPCMS responders. Our results support the premotoneuronal origin of MEP increase for the TA preactivated with comfortable TMS intensities. Larger sampled experimentally designed studies are needed to reproduce our findings, to optimized mPCMS parameters and better understand its underlying mechanisms.

Les cellules souches embryonnaires humaines (hESCs) et les cellules souches pluripotentes induites humaines (hiPSCs) ont démontré leur capacité d'auto-renouvellement et peuvent potentiellement se différencier en tous les types de lignées cellulaires. Elles représentent donc une source illimitée de cellules pour le développement de thérapies curatives pour les maladies dégénératives, telles que la dystrophie musculaire de Duchenne (DMD). Cette maladie héréditaire est le résultat de diverses mutations dans le gène de la dystrophine. Ces mutations engendrent un changement dans le cadre de lecture du gène de la dystrophine, abolissant ainsi son expression. Elle se caractérise cliniquement par une progression rapide de la dégénérescence musculaire qui débute tôt dans la vie. Les hiPSCs dystrophiques ont été corrigées par notre collaborateur, le Dr. Hotta, en insérant une paire de bases dans l’exon 45 avec les Transcription Activator-Like Effector Nucleases (TALENs) pour rétablir le cadre de lecture du gène. Notre laboratoire a mis au point une procédure en deux étapes pour différencier des hiPSCs en cellules myogéniques. Nous avons d'abord utilisé un milieu de culture myogénique préparé spécialement dans le laboratoire (appelé MB1) pour promouvoir la différenciation des hiPSCs en cellules de type mésenchymateuses. Nous les avons ensuite transduites avec un lentivirus exprimant MyoD, un facteur de transcription myogénique sous le contrôle du promoteur synthétique CAG, afin d'induire leur différenciation en myoblastes. Ces myoblastes modifiés ont été greffés dans le muscle Tibialis anterior d’une souris Rag/mdx, un animal immunodéficient et dystrophique, et ont par la suite fusionné avec les fibres musculaires existantes. La présence de la protéine dystrophine humaine a été confirmée par immunohistofluorescence dans les muscles greffés avec les cellules corrigées génétiquement ainsi que dans le contrôle positif réalisé avec des myoblastes provenant d'un donneur sain. La thérapie cellulaire homotypique à partir de cellules corrigées génétiquement présente de grands avantages pour les patients souffrant de DMD, car elle permet l’expression d’un gène capable de produire une dystrophine fonctionnelle dans les fibres musculaires, de diminuer les risques de rejet de la greffe et d’accroitre la capacité de régénération du muscle et la force musculaire. / Human embryonic stem cells (hESCs) and human-induced pluripotent stem cells (hiPSCs) have shown self-renewal capacity and can potentially differentiate into all types of cell lineages. They represent an unlimited source of cells for the therapy of degenerative diseases, such as Duchenne Muscular Dystrophy (DMD), a disease characterized by a rapid degeneration of muscles that starts early in life. Dystrophic hiPSCs have been corrected by our collaborator, Dr. Hotta, by inserting of a single base pair in the exon 45 with Transcription Activator-Like Effector Nucleases (TALENs) to restore the reading frame of the gene. Our laboratory has developed a two-step procedure to differentiate hiPSCs into myogenic cells. We first used a myogenic culture medium especially developped in the laboratory (called MB-1) to promote the differentiation of hiPSCs into mesenchymal-like precursor cells. We next transduced them with a lentivirus expressing the myogenic transcription factor MyoD under the control of the composite CAG promoter, in order to induce their differentiation into myoblasts. Transduced cells have been grafted in the Tibialis anterior muscle of Rag/mdx mice where they fused with existing muscle fibers. The presence of the human dystrophin protein has been confirmed by immunohistofluorescence in muscles grafted with the genetically corrected cells and in a control graft with myoblasts of a healthy donor. Cell therapy shows great promises for DMD patients since it allows the expression of a normal gene capable of producing a functional dystrophin in muscle fibers and increase the regenerative capacity of the muscle and the muscle strength.

INTRODUÇÃO: Estudos experimentais e clínicos, realizados por diversos autores, demonstraram a susceptibilidade à compressão nervosa periférica na vigência da diabetes mellitus e modificações na evolução natural da doença após descompressões nervosas cirúrgicas dos sítios propícios a constrição neural. Em membros inferiores, a síndrome do túnel do tarso sobreposta às neuropatias vigentes ainda gera conflitos na literatura. A anatomia do nervo tibial e seus ramos ao nível do terço distal da perna e túnel do tarso apresentam variações importantes que não são contempladas nos livros texto e atlas de anatomia. OBJETIVO: Determinar, através de dissecção em cadáveres frescos, a anatomia topográfica do nervo tibial e seus ramos ao nível do tornozelo, em relação ao túnel do tarso. MATERIAL E MÉTODOS: O estudo foi realizado através da dissecção anatômica bilateral de 26 cadáveres frescos. Foi fixada, entre o cento do maléolo medial e o centro do calcâneo, uma linha de referência (eixo maleolar-calcaneal). Com base nesse eixo as localizações da bifurcação do nervo tibial e dos ramos calcâneos mediais e inferiores foram aferidas em milímetros. Para as bifurcações foi estabelecida uma classificação por tipos de I a V, baseada no posicionamento em relação ao túnel do tarso (definido como dois centímetros proximais e distais ao eixo). Para os ramos calcâneos, a quantidade e seus respectivos nervos de origens também foram analisados. Os resultados foram transformados em taxas (porcentagem) e comparados aos achados de outros estudos. RESULTADOS: Vinte e seis cadáveres (50 pernas) foram pesquisados. A bifurcação do nervo tibial ocorreu sob o túnel em 88% dos casos e proximalmente em 12%. Tivemos o tipo I em 52%, tipo II em 14%, tipo III em 22%, tipo IV em 12% e o tipo V não foi visualizado. Quanto ao ramo calcâneo medial encontramos: um (58%), dois (34%) e três (8%), com a origem mais comum ocorrendo do nervo tibial (90%). De um total de 75 ramos calcâneos mediais dissecados, 40 tiveram sua origem fora do túnel proximalmente (53,3%) e os demais dentro. Com referência ao ramo calcâneo inferior, constatou-se a presença de um único ramo por perna, com 92% emergindo sob o retináculo flexor, 4% proximalmente e 4% distalmente a ele. A origem mais comum foi do nervo plantar lateral (70%), seguida do nervo tibial (18%). CONCLUSÕES: 1- A bifurcação do nervo tibial nos ramos plantares medial e lateral ocorreu sob o retináculo flexor em 88% das pernas, localizando-se, em 70% das vezes, em uma área compreendida entre 10 mm proximais e distais ao EMC. 2- O ramo calcâneo medial apresentou grande variação tanto na sua origem e número de ramos quanto na sua localização em relação ao túnel do tarso. A apresentação de um ramo com origem do nervo tibial, no túnel ou proximalmente a ele, foi a mais observada (58%). 3- O ramo calcâneo inferior esteve sempre presente e com certo grau de variação quanto a sua origem. A apresentação de ramo único oriundo do nervo plantar lateral foi a mais constante (70%) / INTRODUCTION: Experimental and clinical studies developed by several authors displayed the susceptibility to peripheral nerve compression in the presence of diabetes mellitus and changes in the natural evolution of the disease after surgical nerve decompressions of the propitious sites of neural constriction. In lower members, the tarsal tunnel syndrome overlapped on neuropathies still generates conflicts in the available literature. The tibial nerve and its branches anatomy at the distal leg level present significant variations that are not contemplated in textbooks and anatomy atlas. OBJECTIVE: Determine through dissection in fresh cadavers, the topographic anatomy of the tibial nerve and its branches at the ankle, in relation to the tarsal tunnel. MATERIAL AND METHODS: The study was accomplished through bilateral anatomical dissection of 26 fresh cadavers. A reference line was fixed between the center of medial malleolus and the center of calcaneus (malleolarcalcaneal axis - MCA). Based on this axis, the locations of the tibial nerve bifurcation and its medial and lower calcaneal branches were measured in millimeters. For the bifurcations, it was established a classification by types I to V, based in positioning related to the tarsal tunnel (defined as two centimeters proximal and distal to the axis). For the calcaneal branches, the amount and their respective nerves of origin were also analyzed. The results were transformed in rates (percentages) and compared with findings of other studies. RESULTS: Twenty six cadavers (50 legs) were investigated. The tibial nerve bifurcation occurred under the tunnel in 88% of the cases and proximally in 12%. The study had the type I in 52%, type II in 14%, type III in 22%, type IV in 12% and type V was not visualized. As for the medial calcaneal branch it was found: one (58%), two (34%) and three (8%), with the most common source occurring in the tibial nerve (90%). A total of 75 medial calcaneal branches dissected, 40 had their origin outside the tunnel proximally (53.3%) and others had within. With reference to the lower calcaneal branch, it was detected the presence of a single branch per leg, with 92% emerging under the flexor retinaculum, 4% proximally and 4% distally to it. The most common origin was the plantar lateral nerve (70%) followed by the tibial nerve (18%). CONCLUSIONS: 1- The bifurcation of the tibial nerve in the medial and lateral plantar branches occurred under the flexor retinaculum in 88% of the legs, locating, 70% of the time, in an area between 10 mm proximal and distal to the MCA. 2- The medial calcaneal branch presented wide variation as much in its origin as in its location in relation to the tarsal tunnel. The presentation of one branch originating from the tibial nerve in the tunnel or proximally to it was the most observed (58%). 3- The lower calcaneal branch was always present and with a certain degree of variation related to its origin. The presentation of a single branch from the lateral plantar nerve was the most constant (70%)

A contração muscular gerada por impulsos elétricos provenientes de duas fontes nervosas distintas pode ser alternativa no tratamento de lesões do plexo braquial e na paralisia facial. O objetivo desta tese foi avaliar e comparar diferentes técnicas de reinervação dupla com a técnica de reinervação única do músculo gastrocnêmio em ratos. Cinquenta ratos Wistar adultos, após terem seu nervo fibular direito seccionado, foram divididos em cinco grupos com relação ao procedimento realizado no nervo tibial: controle (C); seccionado (S); neurorrafia término-terminal (TT); neurorrafia primária associada à transferência nervosa fibular para tibial de maneira término-lateral (TL); e neurorrafia término-terminal convergente entre os cotos proximais dos nervos tibial e fibular com o coto distal do nervo tibial (TTC). Os resultados foram avaliados 12 semanas após o experimento por meio do teste da marcha, eletromiografia, índice de massa do músculo gastrocnêmio e contagem axonal no coto distal do nervo tibial. Os grupos de reinervação dupla (TL e TTC) revelaram maiores resultados funcionais (p < 0,05) em relação ao grupo de reinervação única (TT). O grupo TTC apresentou maior amplitude (p=0,006) e maior latência (p=0,041) do que o grupo TT. Em relação ao índice de massa muscular, não houve diferença entre os grupos de reinervação (p > 0,705). A análise histológica revelou maior densidade axonal no grupo TTC em relação ao grupo TT (p=0,001) e ao grupo TL (p=0,002). Ambas técnicas de dupla reinervação revelaram recuperação funcional do músculo gastrocnêmio mais precoce e maior quando comparadas à técnica de reinervação única (TT). Os animais do grupo TTC apresentaram maior número de axônios regenerados no coto distal do nervo tibial do que os do grupo TT e TL / Muscle contraction generated by electrical impulses simultaneously originating from two different neural sources may be an interesting treatment alternative for facial palsy and brachial plexus injury. The purpose of this thesis was to evaluate and compare distinct double reinnervation techniques with single reinnervation technique of gastrocnemius muscle in rats. Fifty adult Wistar rats underwent transection of their right peroneal nerve and were divided into five groups related to tibial nerve procedure: the control group (C), tibial nerve section group (S), tibial nerve end-to-end neurorrhaphy (EE) group, tibial nerve primary repair associated with end-to-side peroneal-to-tibial nerve transfer (ES) group, and tibial nerve repair by convergent end-to-end neurorrhaphy between the proximal stumps of the tibial and peroneal nerves to the distal stump of the tibial nerve (CEE) group. The outcomes were assessed 12 weeks after the experiment by use of a walking track, electromyography, gastrocnemius muscle mass index, and histomorphometric analysis of the distal tibial nerve. The double reinnervation groups (ES and CEE) showed greater functional recovery (p < 0.05) than the single reinnervation group (EE). The CEE group showed greater amplitude (p=0.006) and higher latency (p=0.041) than the EE group. There was no difference in the muscle mass index among the reinnervation groups (p > 0.705). Histologic analysis revealed greater axonal density in the CEE group than EE group (p=0.001) and ES group (p=0.002). The double reinnervation techniques showed earlier and greater functional recovery of the gastrocnemius muscle than did the single reinnervation technique. The CEE group showed a higher number of regenerated axons in the distal tibial nerve stump

INTRODUÇÃO: A Bexiga Hiperativa é uma síndrome de alta prevalência que acomete negativamente a qualidade de vida das mulheres. Os sintomas clínicos se manifestam por urgência miccional, com ou sem incontinência de urgência, frequência e nocturia. O diagnóstico é definido a partir dos sintomas clínicos, sendo o diário miccional um bom instrumento de avaliação. O tratamento fisioterapêutico da bexiga hiperativa tem como opções a eletroestimulação transcutânea do nervo tibial ou eletroestimulação vaginal. OBJETIVO: verificar se a adição da eletroestimulação vaginal à eletroestimulação transcutânea do nervo tibial é mais eficaz do que somente a eletroestimulação no nervo tibial para o tratamento de mulheres com bexiga hiperativa. MÉTODO: Estudo controlado aleatorizado com 106 mulheres, maiores de 18 anos, com diagnóstico de bexiga hiperativa ou incontinência urinária mista com predomínio dos sintomas de bexiga hiperativa. As pacientes foram distribuídas em dois grupos: Grupo 1: eletroestimulação transcutânea do nervo tibial (n=52) e Grupo 2: eletroestimulação vaginal mais eletroestimulação transcutânea do nervo tibial (n=54). Ambos os grupos foram orientados quanto à terapia comportamental. Os instrumentos de avaliação utilizados foram: Diário Miccional de três dias, avaliação funcional do assoalho pélvico, King´s Health Questionnaire e Overactive Bladder Questionnaire, todos aplicados por um avaliador cego, antes e após o tratamento que teve duração de 12 semanas, 1x/semana. O desfecho primário foi a frequência urinária em 24 horas. Os desfechos secundários foram os outros sintomas da bexiga hiperativa, o impacto na qualidade de vida e a funcionalidade do assoalho pélvico. RESULTADO: a frequência urinária no grupo 2 diminuiu em 1,5 vezes em relação ao grupo 1. Contudo este resultado não foi clinicamente relevante pois foi inferior a 3 micções. As outras variáveis do diário miccional bem como como o impacto na qualidade de vida, não apresentaram diferenças entre os grupos. CONCLUSÃO: a adição da eletroestimulação vaginal à eletroestimulação transcutânea do nervo tibial não apresentou resultados mais efetivos na melhora dos sintomas ou na qualidade de vida das pacientes com BH / INTRODUCTION: Overactive Bladder is a syndrome with a high prevalence that negatively affects women\'s quality of life. The clinical symptoms are manifested as urinary urgency, with or without urgency incontinence, frequency and nocturia. The diagnosis is defined based on the clinical symptoms, and the voiding diary is a good assessment. The physiotherapeutic treatment of OAB has as treatment\'s options the transcutaneous tibial nerve electrical stimulation or vaginal electrical stimulation. OBJECTIVE: to verify if the addition of vaginal electrical stimulation to transcutaneous tibial nerve electrical stimulation is more effective than only the electrical stimulation in the tibial nerve for the treatment of women with OAB. METHOD: Randomized controlled trial with 106 women over 18 years old with a diagnosis of overactive bladder or mixed urinary incontinence with predominance of overactive bladder symptoms. The patients were distributed into two groups: Group 1: transcutaneous tibial nerve electrical stimulation (n = 52) and Group 2: vaginal electrical stimulation plus transcutaneous tibial nerve electrical stimulation (n = 54). Both groups received instructions about behavioral therapy. The assessments used were: Three-day voiding diary, functional evaluation of pelvic floor, King\'s Health Questionnaire and Overactive Bladder Questionnaire, all of them applied by a blind evaluator, before and after 12-week treatment, once a week. The primary outcome was urinary frequency in 24 hours. Secondaries outcomes were other overactive bladder symptoms, impact in quality of life, and pelvic floor functionality. RESULTS: urinary frequency in group 2 decreased 1.5 times in relation to group 1. However, this result was not clinically relevant since it was less than 3 mictions. The other variables of voiding diary and impact on quality of life did not present differences between groups. CONCLUSION: The addition of vaginal electrical stimulation to transcutaneous tibial nerve electrical stimulation did not present more effective results in the improvement of symptoms or quality of life in patients with overactive bladder

Base teórica: Disfunções do trato urinário inferior são sintomas não motores comuns na Doença de Parkinson (DP) e incluem a Síndrome da Bexiga Hiperativa Neurogênica (SBHN), caracterizada pela urgência miccional, com ou sem urgeincontinência, acompanhada de aumento da frequência urinária e noctúria. A estimulação do nervo tibial posterior (ENTP) é uma das modalidades de tratamento disponíveis para o tratamento da SBHN. Objetivo: Determinar e comparar os efeitos do tratamento com ENTP em pacientes com DP e sintomas de SBHN e a manutenção dos resultados em 1 e 3 meses após o término do tratamento. Métodos: Ensaio-clínico, duplo-cego, randomizado, controlado e comparado com placebo. A pesquisa foi realizada com mulheres com DP e sintomas de SBHN no Hospital de Clínicas de Porto Alegre. Para o tratamento com ENTP domiciliar por 12 semanas as pacientes foram divididas em dois grupos: grupo ENTP e grupo ENTP sham/placebo. A avaliação da resposta pré e pós-tratamento foi realizada através de formulário específico, questionários de avaliação da incontinência urinária e qualidade de vida (OAB-V8 e KHQ) e de um diário miccional (DM) de 24 horas. Após, o fim do tratamento foi feito seguimento dos resultados para avaliação da melhora subjetiva em 30 e 90 dias. Resultados: O grupo ENTP apresentou uma diminuição da noctúria, número de episódios de urgência micciional e urge-incontinência, número de uso de proteções para incontinência, pontuação OAB-V8 e em sete domínios do KHQ (p <0,001). Embora, o grupo controle também tenha apresentado melhora dos sintomas, o grupo ENTP apresentou uma melhora superior no final do tratamento nas medidas do DM, OAB-V8 e na maioria dos domínios do KHQ. A ETNTP foi considerada um tratamento efetivo para SBHN em 93,3%, enquanto 33,3% dos tratados com placebo também melhoraram (p = 0,002). No seguimento de 30 e 90 dias, 53,3% e 33,31%, respectivamente, do grupo ENTP relataram que mantinham- se melhores dos sintomas da SBHN. Conclusão: a ENTP foi um tratamento efetivo para as pacientes com DP e SBHN. Nossa hipótese de superioridade clínica do grupo ENTP foi confirmada e a melhora subjetiva foi considerada positiva, mesmo que parcialmente em 30 e 90 dias após fim do tratamento. / Blackround: Lower urinary tract dysfunctions are common non-motor symptoms in Parkinson's disease (PD) and include Neurogenic Overactive Bladder Syndrome (NOBS), characterized by urinary urgency, with or without urge incontinence, accompanied by increased urinary frequency and nocturia . Posterior Tibial Nerve Stimulation (PTNS) is one of the treatment modalities available for the treatment of NOBS. Objective: To determine and compare the effects of PTNS treatment in patients with PD and NOBS symptoms and to maintain long-term results (1 and 3 months). Methods: Controlled, randomized, double-blind and compared with placebo clinical trial. The research was carried out with women with PD and symptoms of NOBS at the Hospital de Clínicas de Porto Alegre. For treatment with PTNS at 12 weeks, patients were divided into two groups: PTNS group and PTNS sham/placebo group. The evaluation of the pre- and post-treatment response was through a specific form, questionnaires to evaluate incontinence and quality of life (OVA-V8 and KHQ), and a voiding diary. After the end of the treatment, the results were followed up to evaluate the subjective improvement in 30 and 90 days. Results: The PTNS group presented a decreased nighttime urinary frequency, number of urgency and urinary incontinence episodes, number of incontinence protection, OAB-V8 and 7 domains of KHQ (p<0.001). Although the control group also showed improvement of the symptoms, the ENTP group presented a superior improvement at the end of the treatment in DM, OAB-V8 and most KHQ domains. PTNS was considered an effective treatment for OAB in 93.3%, while 33.3% of those treated with placebo was considered a responder (p=0.002). After 30 and 90 days, 53.3% and 33.31%, respectively, of the ENTP group reported that they maintained better SBHN symptoms. Conclusion: PTNS was an effective treatment for patients with PD and NOBS. Our hypothesis of clinical superiority of the ENTP group was confirmed and the subjective improvement was considered positive, even if partially at 30 and 90 days after the end of the treatment.!
