AIM: Patients with pulmonary tuberculosis (TB) tends to have limited exercise tolerance and a significant disability affecting their activities of daily living. The importance of exercise in the management of these patients has not been well investigated. This study was designed to assess the cardiovascular fitness of patients with pulmonary TB using the six-minute walk test (6-MWT).
METHOD: Sixty five consented patients with Pulmonary TB were consecutively recruited into the study. The patients performed 6-MWT over a 30 meter course on a level walkway at a speed as fast as they could. Data were obtained on participantsâ€™ physical characteristics, pre and post exercise blood pressure and heart rate, and maximum oxygen consumption. Data were analyzed using descriptive statistics of mean and standard deviation and paired t-test.
RESULTS: The post walk test cardiovascular parameters were significantly higher than the resting cardiovascular parameters. The mean VO2 max and MET of the participants were 11.7±0.97 (ml O2kg -1min-1) and 3.35±0.28 (mL/Kg) respectively. The means 6-MWT distance for male and female participants were 502.0±43.0m 481.7±68.3m respectively.
CONCLUSION: The result implies that the 6-MWT is capable of evoking a significant cardiovascular change among patients with pulmonary TB. The 6-MWT may be useful in the assessment of functional capacity of patients with pulmonary TB.
