PURPOSE:To investigate the efficiency of electrical stimulation in the muscle maintenance and nerve regeneration after end-to-side neurorrhaphy (ESN). METHODS:Sixty male Wistar rats (Rattus norvegicus) were divided into four experimental groups. Control group (Control), Denervated Group (Denervated); Group with End-to-side neurorrhaphy (ESN); Group with End-to-side neurorrhaphy and electrical stimulation (ESN + ES). We perform electrical stimulation in rats after they had undergone muscle reinnervation by ESN. We collected morphometric and functional data. RESULTS:When comparing the mass of the treated side of cranial tibial muscle (CTM) and that of normal side of CTM, the group ESN + ES (26.12%) exhibited lower mass loss than that of group ESN (37.23%). The peroneal functional index showed that group ESN + ES equaled that of the Control group and showed an evolution of 60.5% while group ESN showed an evolution of 9.5%. In measuring maximum strength of CTM, the group ES + ESN outperformed group ESN. The muscle and nerve morphometry showed superiority of group ES+ESN over ESN group in all parameters. CONCLUSION:Electrical stimulation is an effective means of maintaining functional muscle and nerve regeneration after end-to-side neurorrhaphy.
End-to-side versus end-to-end neurorrhaphy at the peroneal nerve in rats 1 2-Experimental SurgeryActa Cir Bras. 2017;32(9):697-705 Abstract Purpose: To evaluate three different kinds of neurorrhaphy of the peroneal nerve. Methods: Eigthy rats were divided into 5 groups. Control: nerve had no intervention. End-toend (EE): nerve was cut and elongated with a nerve graft with two end-to-end neurorrhaphies. End-to-side (ES): nerve was cut and sutured to the graft with at the lateral side of the nerve. Side-to-end (SE): the nerve was cut and sutured to the graft with end-to-end neurorrhaphy. Denervated: nerve was cut and both endings were buried into the muscle. The evaluation was done by walking track analysis, electrophysiology, body mass, cranial tibial muscle mass, nerve and muscle fibers morphometry. Results: The EE, ES and SE have the same potential of reinnervation. Conclusion: There is no functional or histological difference between these different types of neurorrhaphy.
PURPOSE:Compare two new methods with the traditional end-to-side neurorrhaphy. METHODS: Rats were divided into four groups. In A-L group the peroneal nerve was sectioned and the distal stump was connected to the lateral of the tibial nerve (donor) with two 10-0 nylon points. In A-R group two perineurium flaps embraced the donor nerve. In the B-R group a suture embraced the donor nerve. Group B-L was the control. After six months tibial cranial muscle mass and morphometry of the distal stump of the peroneal nerve were evaluated. RESULTS:Muscle mass in groups A-R, A-L and B-R were lower than B-L group (p<0.0001) an equal between themselves (p>0.05).Groups A-R, B-R and A-L had a lower number of nerve fibers when compared with B-L (p=0.0155, p=0.016, p=0.0021). CONCLUSION:The three types of neurorrhaphy showed no differences related to muscle mass and number of nerve fibers suggesting that the embracing with a single suture has great potential due its simplicity and usefulness in deep areas. CONCLUSÃO: Os três tipos de neurorrafia não apresentaram diferenças relacionadas à massa muscular e número de fibras nervosas sugerindo que a sutura abraçante com apenas um ponto apresente grande potencial em áreas cirúrgicas mais profundas.Descritores: Neurorrafia término-lateral.

Introdução: Espondilolistese é o deslocamento anterior de uma vértebra sobre a outra. Essa condição patológica prevalece na região lombar, visto que esta recebe maiores impactos no corpo humano. As lombalgias, atualmente são consideradas problemas de saúde pública e podem afetar aproximadamente 80% da população adulta em algum momento da vida. Objetivo: Avaliar a eficácia do tratamento convencional na redução do quadro álgico da espondilolistese, através do Pilates Reformer e exercícios isométricos. Material e métodos: A mostra foi composta por um paciente do sexo feminino de 42 anos participante do programa de estágio obrigatório no Centro Integrado de Movimentos – FLUXO, pelo curso de Fisioterapia da Faculdade Martha Falcão, Amazonas. Para a avaliação foi utilizado o método comparativo e observacional da ficha de avaliação padrão no período pré (AVI Outubro de 2021) e pós-intervenção (AVF Novembro de 2021) do estagio na clínica de reabilitação e ficha de evolução da paciente. Aplicou-se a escala de intensidade da dor que consiste em uma mensuração numérica e verbal que mostra o grau da dor do paciente de 0 – 10. As sessões terapêuticas totalizaram 12 encontros semanais por três vezes na semana com 1 hora de intervenćão. Os exercícios utilizados no pilates variavam com Side Split, Roll Up, Roll Over e fortalecimento de rotadores e tríceps, além disso, realizou-se os exercícios de prancha isometrica com e sem a bola suíça, agachamento com halteres, elevação pélvica dinâmica e isometrica e abdominais oblíquos e transversos. Resultados: Evidenciou-se que a atividade física diminuiu a intensidade da dor de 8 - 9 para 1 a 1,5, houve permanência da fadiga muscular do grupo abdominal, porém, melhor estabilização do iliocostal e multífido. Ademais, a força gerada durante a extensão da coluna vertebral após a exaustão induzida pelos exercícios isométricos apresentou melhora no tempo de cronometragem para a realização dessas atividades. Observaram-se melhoras nas atividades de vida diária e a independência na administração de fármacos analgésicos para o controle da dor. Conclusão: A escolha terapêutica convencional, portanto, colaborou para a melhoria da dor na paciente e tais resultados somam as evidências cientificas quanto à prevenção e tratamento no manejo da dor lombar.
