As a dual GLP-1 and GIP receptor agonist, Tirzepatide affects multiple pathways simultaneously: It slows gastric emptying, enhances insulin secretion in a glucose-dependent manner, suppresses glucagon secretion, and powerfully suppresses appetite
Walking Recovery Index (WRI) As described previously [13], to objectively measure gait recovery, recordings were carried out using a fixed digital camera placed under the animals (Olympus mju 300 digital, Olympus Optical Co., Ltd., Hachioji, Tokyo, Japan), located 25 cm below and 12 cm to the side of a 100 cm long closed transparent plexiglass tunnel, and measurements and the gait recovery index were calculated, expressed as a coefficient of the length of the footprints with which the animal rests on the ground in certain phases of walking, according to the following Equation (1): where NPL stands for the non-injured animal footprint length, while EPL stands for the experimental animal footprint length, expressed in millimeters
