Product Description:

The time it takes between consecutive foot contacts from the same leg is referred to as the stride-time interval. Several investigations have shown that the variations that are present in the stride-time intervals are linked to walking balance. In this study, functional near infrared spectroscopy (fNIRS) was utilized to evaluate whether activation in the medial sensorimotor cortices reflects the amount of variations seen in the stride-time intervals. Thirteen healthy adults (Age = 23.7 plus/minus 1.4 yrs) walked forwards and backwards on a programmable treadmill. Each walking condition consisted of two sessions, with each being comprised of five alternating blocks of standing still or walking at 9.45 m/s. Activation in the medial sensorimotor cortices was measured using an fNIRS system, which consisted of a 4x4 grid of infrared optode emitter/detector pairs.
