Desempeño físico en pacientes con esclerosis lateral amiotrófica y su relación con el uso de silla de ruedas y ayuda para la marcha / Physical performance in patients with amyotrophic lateral sclerosis and its relationship with wheelchairs and walking aids use

Introducción y objetivos: El déficit de marcha y las caídas en pacientes con esclerosis lateral amiotrófica (ELA) restringen la movilidad. El objetivo de este estudio es examinar el uso apropiado de dispositivos de ayuda para la marcha y silla de ruedas para deambular basados en el riesgo de caídas y la velocidad de marcha de pacientes con ELA. Métodos: Se incluyeron datos retrospectivos de pacientes de la clínica ELA. Se registraron edad, género, tiempo de evolución, uso de silla de ruedas, dispositivo de ayuda para la marcha, velocidad de marcha y escala de Berg. Se relacionaron las variables categóricas con la prueba de chi cuadrado y test exacto de Fisher. Resultados: Cincuenta y ocho pacientes cumplieron con los criterios de inclusión. Veintisiete (46,55%) tuvieron uso adecuado de silla de ruedas basado en la velocidad de marcha (p=0,50). Esta asociación disminuye al 6% en pacientes que caminaron a velocidad menor a 0,88m/s. Cuarenta y dos (70,69%) tuvieron uso adecuado de dispositivo de ayuda para la marcha basado en el riesgo de caídas (P=0,001). Del subgrupo con puntaje de Berg ≤ 45, el 38% no empleó el dispositivo apropiado (p=0,06). Conclusiones: Los pacientes con severo déficit de equilibrio y de marcha tuvieron un uso inapropiado de dispositivos para caminar y/o silla de ruedas. Los hallazgos del presente estudio pueden significar un aporte que podría ser considerado en las evaluaciones clínicas de pacientes con ELA para minimizar los riesgos y mejorar la participación de este colectivo de personas.

Introduction and objectives: Gait deficits and falls in patients with amyotrophic lateral sclerosis (ALS) restrict mobility. The aim of this study is to examine the appropriate use of walking aids and wheelchairs, based on the risk of falling and walking speed of patients with ALS. Methods: Retrospective data from patients from the ALS clinic were included. Age, gender, evolution time, wheelchair use, walking aids, gait speed and the Berg Balance Scale were registered. Categorical variables were related to the Chi Square test and Fisher's exact test. Results: Fifty eight patients met the inclusion criteria. Twenty-seven (46.55%) had adequate use of a wheelchair based on walking speed (p=.50). This association decreases to 6% in patients who walked at a speed lower than 0.88m/s. Forty-two (70.69%) had adequate use of an assistive device based on the risk of falls (p=.001). Of the subgroup with Berg Balance score ≤ 45, 38% did not use the appropriate device (p=.06). Conclusion: Patients with severe gait and balance deficits had inappropriate use of walking aids and/or wheelchairs. The findings of this study may mean a contribution that could be considered in the clinical evaluations of patients with ALS to minimize risks and improve the participation of this group of people.(AU)
