Objectives

1) To determine the frequency of use of the 6-minute walk test in pulmonary rehabilitation programs in Latin America and on the Iberian Peninsula; 2) to identify how the test is performed and possible variations from center to center.

Material and methods

A questionnaire was sent to 55 pulmonary rehabilitation centers in Latin America, Portugal, and Spain.

Results

: Forty-nine (89.1%) centers answered the questionnaire. Forty-seven (95.9%) perform a walk test lasting 6 minutes; 22 (46.8%) take the longest distance of 2 tests as the real one; and 35 (74.5%) carry out the test in a corridor. The course distance ranged from 17 to 90 meters, but in 21 (44.7%) centers, the corridor was between 17 and 30 meters long. In 29 (61.7%) centers, the patients are routinely informed about the time that had elapsed during the test. Verbal encouragement is used in 44 (93.6%) centers. Thirty-eight (80.8%) use supplemental oxygen when a patient needs it. An increase in absolute values in the distance covered is used as a parameter indicating improvement at 21 (46.7%) sites while at 15 (33.3%) other centers the percentage increase is taken as a measure of improvement.

Conclusions

The 6-minute walk test is widely used for the evaluation of the exercise capacity at the pulmonary rehabilitation centers of Latin America and the Iberian Peninsula. However, there is great variability in the way the test is performed.

Objetivos

Determinar la frecuencia de utilización de la prueba de la marcha de 6 min en el contexto de los programas de rehabilitación pulmonar que se llevan a cabo en América Latina y en la Península Ibérica. Definir la forma con la que se realiza esta prueba y las posibles variaciones que presenta en los distintos centros.

Material y métodos

Se remitió un cuestionario a 55 centros de rehabilitación pulmonar localizados en América Latina, Portugal y España.

Resultados

Respondieron al cuestionario 49 centros (89,1%); en 47 (95,9%) se realizó la prueba de la marcha con una duración de 6 min; en 22 (46,8%) se aceptó la mayor distancia recorrida por el paciente en 2 pruebas como el valor real de la prueba de la marcha; en 35 (74,5%) se realizó la prueba de la marcha en un pasillo; la distancia recorrida osciló entre 17 y 90 m, pero en 21 centros (44,7%) el pasillo tenía una longitud de 17 a 30 m. En 29 centros (61,7%) se informó sistemáticamente a los pacientes del tiempo transcurrido durante la prueba de la marcha; en 44 (93,6%) se animó verbalmente al paciente mientras realizaba la prueba; en 38 (80,8%) se utilizó oxígeno suplementario cuando el paciente lo necesitó. El incremento de los valores absolutos en la distancia recorrida se utilizó como parámetro para determinar la mejoría en 21 centros (46,7%), mientras que en otros 15 (33,3%) se utilizó como parámetro de mejoría el porcentaje de incremento en la distancia recorrida.

Conclusiones

La prueba de la marcha de 6 min se utili-za con mucha frecuencia para la evaluación de la capacidad de ejercicio de los pacientes en los centros de rehabilitación pulmonar de América Latina y de la Península Ibérica. Sin embargo, hay grandes variaciones en la forma con la que se lleva a cabo la prueba.
