Example accelerometer vector magnitude from a single individual during the 6MWT. a A ten-second period of smooth walking without any turns. The “good walking” algorithm identifies the full segment as good walking (high green line). b A ten-second period of smooth walking which contains a turn. The “good walking” algorithm identifies the substantial reduction in acceleration magnitude and eliminates this portion of the walk tracing (green line drops down). Note, the first and last 15 data points in any segment are always identified as “non-walking” due to insufficient information
