Abstract (English): A descriptive case study of a single 16-year-old subject diagnosed with Guillain-Barré syndrome, Miller Fisher variant, with a 2-year history of onset. The intervention technique was proprioceptive neuromuscular facilitation (PNF), which was applied for 30 sessions 50 min over a 10-week period. Pre- and post-intervention analyses were performed to assess the results. The following were evaluated: joint range of motion, muscle strength, deep tendon and pathological reflexes, dermatomes, and movements; as well as the application of the functional independence scale and biomechanical gait analysis using Kino-vea 2023 version 1.1 software, assessing the following temporal and spatiotemporal variables: toe-off angle, foot elevation, step length, and gait speed. The intervention resulted in an increase in muscle strength and complete movements, as well as joint and dermatome ranges within the norm. Regarding the biomechanical analysis, there was a decrease in foot elevation on the right side and an increase on the left side, resulting in a difference of 7.45 cm compared to the initial evaluation. There was a decrease in step length bilaterally, a decrease in foot angles bilaterally, and an improvement in speed with a difference of 00.15.24 m/s. It is concluded that PNF can generate favorable changes in the temporal and spatiotemporal. [ABSTRACT FROM AUTHOR]
Abstract (Spanish): Estudio de caso con diseño descriptivo de un único sujeto de 16 años con diagnóstico de Guillain-Barré en la variante de Miller-Fisher con dos años de evolución. La técnica de intervención se realizó por medio de la facilitación neuromuscular propioceptiva (FNP) la cual se aplicó durante 30 sesiones de 50 minutos, por un periodo de 10 semanas, realizando análisis previo y posterior a la intervención para el análisis de resultados. Se evaluaron: rango articular, fuerza muscular, reflejos osteotendinosos y patológicos, dermatomas y mudanzas. También se aplicó la escala de independencia funcional (FIM) y se realizó análisis biomecánico de la marcha mediante el software Kinovea 2023 versión 1.1, valorando las variables temporales y espaciotemporales: ángulo de despegue de pie, elevación de pie, longitud de paso y velocidad de la marcha. Como resultados de la intervención se registró un aumento de la fuerza muscular y mudanzas completas, así como rangos articulares y dermatomas dentro de la norma. En cuanto al análisis biomecánico, hubo una disminución de elevación del pie de lado derecho y aumento del lado izquierdo, dando una diferencia de 7.45 cm respecto a la evaluación inicial, disminución en la longitud de paso de manera bilateral, disminución del ángulo de pie de manera bilateral y mejorando la velocidad con una diferencia de 00.15.24 m/s. Se concluye que la FNP puede generar cambios favorables en los parámetros temporales y espaciotemporales de la marcha, así como mejora de la funcionalidad e independencia en un paciente con síndrome de Miller-Fisher con estas características.
