Table 4

Reliability of the IDEEA monitor for gait counts in walking on a flat and ascending or descending stairs.

	30 steps walking ($N=24$)	Ascend 9 stairs ($N=20$)	Descend 9 stairs down ($N=20$)
Case	28.17 ± 2.37	6.30 ± 1.16	5.90 ± 1.52
Control	29.42 ± 1.56	7.40 ± 0.84	6.50 ± 1.18
Total	28.79 ± 2.06	6.85 ± 1.14	6.20 ± 1.36

For walking count analysis, 24 data points from 2 walking tests in each of 12 participants were used. For stair count analysis, 20 data points from two stair tests in each of 5 cases and 5 controls were used.
