Resumen
Introducción: El Xiaomi Mi Band 4 (XMB4) demostró ser exacto para medir pasos en sujetos sanos, pero no ha sido estudiado en pacientes con enfermedades respiratorias crónicas (ERC).Objetivos: Evaluar la exactitud del XMB4 para cuantificar pasos caminados en pacientescon ERC. Secundariamente, evaluar su viabilidad y usabilidad.Material y métodos: Estudio de concordancia contrastando los datos del XMB4 con la video-filmación (prueba de referencia). Fueron incluidos mayores de 18 años con diversas ERC y excluidos aquellos con deterioro cognitivo, limitaciones osteoarticulares y/o cardiovasculares que impedían la marcha. Realizamos un muestreo por conveniencia de pacientes que participaban de un programa de rehabilitación pulmonar. Las variables estudiadas incluyeron número de pasos, distancia y tiempo caminado, velocidad de la marcha, viabilidad y usabilidad. Cada participante realizó cinco caminatas (5, 10 y 30 metros, y 5 minutos a ritmo lento y rápido). Para testear la equivalencia estadística, necesitamos incluir 33 pacientes y utilizamos el método de intervalo de confianza con una zona de equivalencia de ±15%. Resultados: Fueron incluidos 33 pacientes, 64% mujeres, con una mediana (P25-75) de edad de 64,9 (55,8 a 70,2) años. Los pasos registrados por el XMB4 fueron equivalentes a los de la video-filmación en las diferentes caminatas, excepto en la de 5 metros. Los pasos fueron subestimados con un error de medición menor al 15%. Conclusiones: El XMB4 tiene una exactitud aceptable para medir pasos en pacientes con ERC excepto en caminatas muy cortas, es viable y fácil de usar.
Introduction: Xiaomi Mi Band 4 (XMB4) has been shown to be accurate to measure steps in healthy subjects, but has not been studied in patients with chronic respiratory diseases (CRD). Objectives: To evaluate the accuracy of the XMB4 to quantify steps walked in patients with CRD. Secondarily, evaluate its feasibility and usability. Materials and methods: Agreement study compared the XMB4 data with the video (reference test). Adults aged 18 years or older with various CRD were included and those with cognitive impairment, osteoarticular and/or cardiovascular limitations that prevented walking were excluded. We conducted a convenience sampling of patients participating in a pulmonary rehabilitation program. Outcome measures studied included number of steps, distance and time walked, walking speed, feasibility and usability. Each participant performed five walks (5, 10 and 30 meters, and 5 minutes at a slow and fast pace). To test statistical equivalence we need to include 33 patients and use the confidence interval method with an equivalence zone of ±15%. Results: 33 patients were included, 64% women, with a median (P25-75) age of 64.9 (55.8 to 70.2) years. The steps recorded by the XMB4 were equivalent to those of the video in the different walks, except for the 5-meter walk. The steps were underestimated with a measurement error of less than 15%. Conclusions: XMB4 has acceptable accuracy for measuring steps in patients with CRD except for very short walks, it is feasible and easy to use.
