[The six minute walk test: which predictive values to apply for Tunisian subjects aged between 40 and 80 years?].

Aim: To establish predictive values for the six minutes walk test (6MWT) specific to subjects old more than 40 years from Tunisian population and to compare them with the other pre-established reference equations.

Methods: 155 voluntary Tunisian subjects, including 75 women, from 40 to 80 years old, sedentaries, no smokers, and without acute or chronic pathologies carried 2 TM6m in a hospital corridor on a way of 30 meters length according to the American Thoracic Society recommendations. Covered distance, heart rate and level of dyspnea were given during each 6MWT.
