This video reports a novel low-cost method for assessing gait asymmetries in rats, using a precise locomotor limb-positioning task. The phase durations over a range of walking speeds of the quadrupedal gait are used to calculate an index to score

Here, we present a protocol to quantify precise stepping in rodents. Cortical and the spinal central pattern generator signals are required for precise foot-placement during obstructed locomotion. We report here the novel constrained walking task that directly examines precise stepping behavior.
