Correlation of distance walked in audio signal-modified shuttle walk test with six-minute walk test.

The literature review suggested that the audio signal-modified shuttle walk test (SWTSR) was equally reliable and valid when compared to the conventional shuttle walk test. A comparison of SWTSR with the six-minute walk test (6MWT), which is considered the gold standard in walk tests, allowed us to evaluate the SWTSR and determine its validity and reliability as an alternative or supplement to the 6MWT. The objective of this study was to determine the correlation between the distances walked during a SWTSR and the 6MWT in healthy, normal adults.
