that Gluba's PPD rating was 22 percent whole body under Minn. R. 5223.0390 and two of its subparts. 3 . The judge set March 5, 2003 as the end date for disability benefits based on his conclusion that Gluba had effectively withdrawn from the labor market as of that date and therefore, Gluba's 1996 work injury was no longer a substantial contributing factor to his unemployed and unemployable status. The WCCA ultimately reversed this conclusion, which is not relevant to this appeal. 4 . In combination with one another, subparts 4 and 5 of Minn. R. 5223.0420 assign a PPD rating of 9.25 to a person who has a 4/5 strength grade in muscle groups supplied by injured third, fourth, and fifth lumbar nerve roots. 5 . See Frankhauser v. Fabcon, Inc., 57 Minn. Workers' Comp. Dec. 239, 252 (WCCA) (<HOLDING>), aff'd without opinion, 569 N.W.2d 533
