Avaliação funcional através do teste de caminhada e do degrau de dois e seis minutos em portadores de doença pulmonar obstrutiva crônica.

Abstract

The study evaluated the cardiorespiratory, dyspnea, distance walked (DW) and quantity of steps done (QSD) in the Walking Test and Step Test (ST) apllied for 2 and 6 minutes in COPD patients. Methods: After approval in Ethics and Research Committee of Porto Alegre Methodist University Center, and Metabolic and Cardiorespiratory Rehabilitation Program of Santa Cruz do Sul University, the data collection begun (may/dec, 2007). Twelve COPD patients composed the sample by convenience, and from those patients the antrompometric, pulmonary function cardiorespiratory variables, dyspnea, DW and QSD during WT and ST in pre-pulmonary rehabilitation period were collected. The WT followed the protocol of ATS – Statement: guidelines for the six-minute walk-test (2002), and the ST followed the Brunelli Protocol (2002). It was used the Student t test and Pearsons Correlation with a significance level of p≤0.05. Results: between pre and post tests we found changes in Diastolic Arterial Blood Pressure, Heart Rate (HR), Periferic Oxigen Saturation (SpO2) in the 2 minutes WT; in the SpO2 in the 6 minutes WT, and in the HR and SpO2 in both ST. Between the ST, there was a moderate correlation between HR and SpO2 (r= 0,83; p= 0,001 e r= 0,68; p= 0,013, respectively) and between the WTs only the DW had a moderate correlation (r= 0,7; p= 0,01). Conclusion: The study show a positive correlation between HR and SpO2 in the ST, as well as to DW in WT.
