Table 2. Gait volume.

Parameter	A1	B1	A2	B2
	(Z + 37)	(Z + 51)	(Z + 65)	(Z + 79)
Total walking distance (m)	1,770	1,955	2,515	2,160
Average daily walking distance (m)	136.2 ± 44.5	150.4 ± 35.4	193.5 ± 75.1	166.2 ± 46.5

Gait volume, including total and average daily walking distance, was measured across intervention periods. Total walking distance represents the cumulative walking distance during each period. Average daily walking distance is expressed as mean ± standard deviation (SD). Z: date of onset.
