Hemodynamic Response of the Supplementary Motor Area during Locomotor Tasks with Upright versus Horizontal Postures in Humans

Table 1

Oxy-Hb of SMA for each task. Mean and SD of 10 participants (unit: mmol/l × mm).

Task		Rest phase		Starting phase			Steady phase

Hand-knee crawling (HKQuad)	10	−0.003	0.002	−0.022	0.041	0.1549	−0.069	0.074
Lofstrand crutch gait (UpQuad)	10	−0.002	0.003	0.035	0.045		0.022	0.082	0.3653
Bipedal walking (UpBi)	10	−0.002	0.003	0.013	0.039	0.2656	−0.033	0.052	0.0968

⁢; values are for paired -test between the rest and starting phases and between the rest and steady phases.
Testing was done within each task.
Oxy-Hb, oxygenated hemoglobin.
SMA, supplementary motor area.
SD, standard deviation.
