Evaluation of Exercise Tolerance in South Indian COPD Population Using 5 Sit to Stand Test (5STS) vs. 6 Min Walk Test (6 MWT)

Author(s): Monisha R, Jansi Selvakumari

Background: Sitting to standing is a common activity of daily living. The five-repetition sit-tostand test (5 STS) is a test of lower limb function that measures the fastest time taken to stand five times from a chair with arms folded. 5 STS is reliable, correlates with exercise capacity and quadriceps strength and is responsive to PR in COPD but the data in chronic obstructive pulmonary disease (COPD) populations are lacking.

Aim: The primary objective of this study was to analyze the exercise tolerance of south Indian COPD population using 5 STS patients. The secondary objective was to analyze and compare the course of exercise tolerance measured by 5 STS and 6 MWT in COPD.

Methods: All COPD patients were evaluated for dyspnea and cardio respiratory stress tolerance level and the sample size has been divided into two groups, group A underwent recording of exercise tolerance by performing 6 MWT and group B perform 5 STS.Then these patients received conventional cardio respiratory techniques for 4-5 min per session and 2-3 times per day for six weeks. Responsiveness was determined by measuring 5 STS, 6 MWT patients.

Conclusions: The 5 STS is reliable, valid and responsive in patients with COPD. It is a practical functional outcome measure suitable for use in COPD patients.
