ABSTRACT

STUDY PURPOSE: The overall goal of this study was to provide a baseline for the overground walking in the healthy Yucatan mini pigs. Specifically, we assessed the effect of overground walking speed on various gait kinematic parameters and muscle activities.

DATA COLLECTED: Data were collected from nine neurologically-intact adult, female Yucatan mini pigs. The pigs were trained to traverse a straight 3.5 m walkway by following a human experimenter. A motion capture system was used for recording the biomechanics of walking. Wireless surface EMG electrodes were placed on the left and right gluteus medius (GM) muscles, the biceps femoris (BF) muscles, and the vastus lateralis (VL) muscles. For each pig, motion capture data (150 frames/sec) and EMG activity (3000 Hz) were recorded as the pigs traversed the walkway 20-120 times on a given testing day. different parameters are averaged over many strides in a specific speed range. if less than 6 strides are in a speed range, the data is excluded from the analysis.

CONCLUSIONS: The data presented in this study show a significant decrease in stride duration (from 1.02±0.007 s to 0.50±0.001 s), stance (from 0.66±0.006 s to 0.23±0.002 s), and swing times (from 0.36±0.003 s to 0.27±0.001 s) as the result of increasing speed (from 0.4-0.59 m/s speed range to 1.4-1.6 m/s speed range). An increase in stride length (from 0.52±0.10 m to 0.74±0.008 m) was observed with increasing speed (from 0.4-0.59 m/s speed range to 1.4-1.6 m/s speed range). A transition in gait pattern occurred at the 1.0m/s walking speed can be observed. Significant increases in the range of motion of the knee (from 30.1±6.5 degrees to 49.1±0.7 degrees) and ankle (from 25.1±3.1 degrees to 44.5±2.5 degrees) joints were observed with increasing the speed of overground walking (from 0.4-0.59 m/s speed range to 1.4-1.6 m/s speed range). Also, the points of minimum and maximum joint angles occurred earlier in the gait cycle as the walking speed increased. The onset of EMG activity in the biceps femoris muscle occurred significantly earlier in the gait cycle with increasing speed.
