Passive movement, motor imagery, and observation of movement have been able to activate the somatosensory and motor cortex of brain without voluntary movement. In this paper, we have investigated cortical activation in brain using a finger movement passive mode together with voluntary movement and analysis is based on within-subject design protocol. Five subjects have participated in movement of finger tasks meanwhile their brain activity is monitored using functional near-infrared spectroscopy (fNIRS). The two gamma functions are used to model the conventional hemodynamic response function (cHRF) to determine the active locations. The t-maps (brain maps) are generated for the comparison of oxy-hemoglobin (HbO) responses of both voluntary and passive movement of index finger tasks. The results have demonstrated that both movement modes activated sensorimotor areas. The neural activation pattern in voluntary execution of finger is somewhat similar to passive movement. The results of this study will help in checking whether passive movements can be able to induce suitable amount of somatosensory stimulation. Our results inveterate that the voluntary and passive movement task are strongly coupled, supporting the importance of passive tasks as a diagnostic tool in the clinical setting.
