The purpose of this study was to determine if there was a significant difference between a six week experimental core stability plank exercise program compared to a traditional supine exercise program in the closure of DRA, and to determine the relationship between DRA measurements, pain, ODI, and PFDI scores.
To meet regulations the average single depth grave is about 3-4 feet deep. Already we see that two out of the three grave depths are deeper than 6 feet (or 1.8 meters). Tripple depth is significantly deeper and double depth is noticeably deeper, being almost 7 feet.
In low-lying wetland areas like New Orleans, Miller noted, a grave dug six feet deep would likely fill with water. Graves in such locales are typically less than two feet deep, reducing (but not eliminating) the coffin's chances of gradually floating toward the surface.
