RESUMEN
Objetivo:
Evaluar la concordancia intrasemanal de la medida con un acelerómetro de la actividad física cotidiana en pacientes con enfermedad pulmonar obstructiva crónica (EPOC). Analizar la reproducibilidad del registro a medio plazo. Pacientes ymétodos:
Se estudió a 23 pacientes con EPOC estable cifra media (± desviación estándar) de volumen espiratorio forzado en el primer segundo del 45 ± 13% y cociente entre este parámetro y la capacidad vital forzada del 53 ± 13% y 12 sujetos sanos. Se efectuó un registro con acelerómetro durante una semana y se analizó el vector de desplazamiento (VMU) en el período convencional (viernes a sábado) y en 2 períodos alternativos (lunes a miércoles y martes a jueves). El registro se repitió a las 3-5 semanas.Resultados:
El VMU fue menor en los pacientes con EPOC que en los controles (184 ± 99 frente a 314 ± 75; p < 0,001). En el grupo con EPOC el registro de viernes a domingo mantenía una buena relación con el efectuado de lunes a miércoles (intervalo de concordancia del 95%, -29,21 a 28,81) y con el realizado de martes a jueves (intervalo de concordancia del 95%, -32,13 a 28,43). El coeficiente de reproducibilidad del VMU a medio plazo de los pacientes con EPOC (11,2 ± 4,6%) no resultó ser significativamente diferente del de los controles (8,5 ± 4,7%).Conclusiones:
El registro de la actividad física cotidiana mediante un acelerómetro alcanza una elevada concordancia entre períodos de análisis comprendidos dentro de una misma semana y muestra una notable reproducibilidad a medio plazo, tanto en sujetos sanos como en pacientes con EPOCABSTRACT
Objective:
The purpose of this study was to assess the agreement between different measurements of mean daily physical activity taken over a week in chronic obstructive pulmonary disease (COPD) patients with an accelerometer and to analyze the medium-term repeatability of these measurements. Patients andmethods:
The study enrolled 12 healthy control subjects and 23 patients with stable COPD (mean [SD] forced expiratory volume in 1 second [FEV1] of 45% [13%] of predicted and a ratio of FEV1 to forced vital capacity of 53% [13%]). Accelerometer output, measured in vector magnitude units, was recorded in a physical activity log for a 1-week period. The results were then analyzed to compare output for a conventional recording period (Friday to Sunday) to that for 2 other periods (Monday to Wednesday and Tuesday to Thursday). The measurements were repeated 3 to 5 weeks later.Results:
Activity counts were lower in the COPD patients than in the control subjects (184 [99] vs 314 [75]; P<.001). In the COPD patients, the results for the Friday to Sunday period correlated well with the results for both the Monday to Wednesday period (95% confidence interval, -29.21 to 28.81) and the Tuesday to Thursday period (95% confidence interval, -32.13 to 28.43). There were no significant differences in terms of medium-term repeatability of accelerometer readings between the COPD group and the control group (repeatability coefficient of 11.2% [4.6%] and 8.5% [4.7%], respectively).Conclusions:
Both agreement between the different measurements of physical activity taken during a 1-week period and medium-term repeatability for COPD patients and control subjects were very good
