Introdução: A irradiação pelo método de Facilitação Neuromuscular Proprioceptiva (FNP) ativa grupos musculares fracos estimulando grupos que estão preservados. Objetivo: Avaliar o efeito da irradiação do método FNP sobre a ativação muscular no membro superior parético, quadro clinico e funcionalidade de indivíduos pós-AVE. Metodologia: Estudo piloto, com 6 voluntários, média de 53,33(±19,22) anos, submetidos ao procedimento de irradiação do método FNP no membro superior parético em 3 tarefas distintas. A intervenção durou 8 sessões, 2 vezes semanais e avaliação foi realizada pela escala de Fugl- Meyer, CIF (Classificação Internacional de Funcionalidade) e eletromiografia. Resultados: A CIF e a Fugl- Meyer apresentaram melhora em alguns dados (p<0,05). A análise eletromiográfica não apresentou alterações significativas (p>0,05). Conclusão: A intervenção com uso de irradiação pelo método FNP propiciou ganhos em força e tônus muscular, controle de punho e funções vestibulares e cognitivas, melhorando o convívio com a comunidade e facilitando suas atividades. A eletromiografia não evidenciou mudanças pós intervenção.
Backgrounds: The overflow by the Neuromuscular Proprioceptive Facilitation (PNF) method activates weak muscle groups by stimulating preserved muscle groups. Objective: To evaluate the effect of overflow by the PNF method on muscle activation in paretic upper limb, in the clinical features and also in the functionality in post-stroke individuals. Methods: A pilot study, with 6 volunteers, mean of 53.33 (± 19.22) years old, submitted to the procedure of overflow by the PNF method in the paretic upper limb in 3 distinct tasks. The intervention lasted 8 sessions, 2 times weekly and the evaluation were based on Fugl-Meyer scale assessment, CIF (International Classification of Functionality) and electromyography. Results: The CIF and Fugl-Meyer presented improvement in some data (p <0.05). An electromyographic analysis showed no significant improvement (p> 0.05). Conclusion: The intervention using overflow by the PNF method provided gains in strength and muscle tone, wrist control, and vestibular and cognitive functions, improving community living and facilitating its activities. The electromyography did not show post-intervention changes.

Although numerous studies investigate sensory recovery of the hind paw of the rat after nerve damage, still no comprehensive overview of its normal innervation is present in the literature. We investigated the morphometry of myelinated fibers in the sural and saphenous nerves and analyzed their size distributions in young rats. Six 30-day-old female Wistar rats were perfused with 2.5% glutaraldehyde and their right and left sural and saphenous nerves were prepared for light microscopy and morphometry. Morphometric data were compared between segments (proximal versus distal) and sides (right versus left) for the same nerves. Also, segments from right or left sides were compared between nerves (sural versus saphenous). Both, the sural and saphenous nerves, exhibited proximal to distal symmetry on both sides as well as left-right symmetry. Histograms of the diameter of the myelinated fibers were unimodal in both nerves, regardless of segments or sides with the peaks of the fibers size occurring between 2.5 and 4.0 µm. The axon distributions reflected the myelinated fiber distributions, with the sural and saphenous nerves peaking between 1.5 and 2.0 µm. The G ratio (the ratio between the axon and fiber diameters) distributions were also unimodal, with peaks at 0.6 for both nerves. This study contributes to the literature with information on the myelinated fibers morphometry from the two sensory nerves responsible for the rat hind limb innervation. This information is valuable for a better understanding of the possible contribution of collateral sprouting from the sural or saphenous nerves on the paw sensory territory recovery observed after one of these nerves is damaged.
Aunque numerosos estudios investigan la recuperación sensorial del miembro pélvico o posterior de la rata después del daño en los nervios, aún no existe en la literatura una visión global de su inervación normal. Investigamos la morfometría de fibras mielínicas de los nervios sural y safeno y analizamos sus distribuciones de tamaño en ratas jóvenes. Seis ratas Wistar de 30 días de edad fueron perfundidas con 2,5% de glutaraldehído, se prepararon los nervios sural y safeno derecho e izquierdo para microscopía de luz y morfometría. Datos morfométricos fueron comparados entre los segmentos (proximal vs distal) y laterales (derecho vs izquierdo) para los mismos nervios. Además, los segmentos de los lados derecho e izquierdo se compararon entre los nervios (sural vs safeno). Ambos nervios sural y safeno exhibieron una simetría proximal a distal en ambos lados, así como una simetría izquierda-derecha. Histogramas del diámetro de las fibras mielinizadas eran unimodales en ambos nervios, independientemente de los segmentos o de los lados, siendo los peaks del tamaño de las fibras entre 2,5 y 4,0 micras. Las distribuciones de los axones reflejan las distribuciones de fibras mielinizadas, de los nervios sural y safeno que alcanzaban entre 1,5 and 2,0 µm. La relación de G (relación entre los diámetros de los axones y de fibra) eran también unimodales, alcanzando 0,6 para ambos nervios. Este estudio contribuye a la literatura con los datos de la morfometría de fibras mielinizadas de ambos nervios sensoriales responsables de la inervación de la extremidad pélvica de la rata. Esta información es valiosa para una mejor comprensión de los nervios sural y safeno en la recuperación sensorial del miembro después de que uno de estos nervios ha sido dañado.
