Fig. 2From: Wearable hip-assist robot modulates cortical activation during gait in stroke patients: a functional near-infrared spectroscopy studya Experimental design: the block design time course, including baseline, walking, and resting periods. b Location of optodes. The fNIRS system consists of 16 light source (white) and 16 detector (black) fibers, resulting in a total of 49 channels distributed over left SMC (Channels 1, 9, 42), right SMC (Channels 3, 27, 32), left SMA (Channels 11, 12), right SMA (Channels 24, 25), left PMC (Channels 10, 13, 45), right PMC (Channels 23, 26, 36), left PFC (Channel 16), and right PFC (Channel 20). fNIRS functional near infrared spectroscopy, SMC primary sensorimotor cortex, SMA supplemental motor areas, PMC premotor cortex, PFC prefrontal cortex, GEMS-H walking with assistance of GEMS-H, NoGEMS-H walking without assistance of GEMS-HBack to article page
