Incremental cardiopulmonary test
Endurance test
Functional test
Incremental cardiopulmonary test for upper limbs will be performed only to identify patients who exhibit dynamic hyperinflation during upper limb exercise.
The endurance test for upper limbs will be performed in two conditions: In the first the patients perform the test in usual breathing, without the use of EPAP. In the second the test will be performed using the EPAP mask.
The functional test for upper limbs will be performed from protocol already published for the 6-min pegboard and ring test (6PBRT). In this stage the patients will perform the 6PBRT in usual breathing and as the use of the EPAP mask.
