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.
This opening is then closed with a concrete slab. Grave dimensions for clearances are the same as those of the lowering burial procedure. But the space between the foot of the coffin and the slab should be no more than 0.25 or 0.30 meters. This ensures easy sliding in or out of the coffin.
