Concurrent validity study of QuickDASH with respect to DASH in patients with traumatic upper extremity amputation

Table 2 Comparisons of mean DASH and QuickDASH scores according to injury level

Level of injury	DASH score mean (SD)	QuickDASH score mean (SD)	MD (95% CI)	p
All participants	19 (18)	20 (19)	-1 (-1 to 0)	0.02
Injury level distal to carpus	18 (17)	18 (18)	0 (-1 to 0)	0.10
Injury level proximal to carpus	33 (19)	36 (20)	-2 (-4 to 0)	0.03

DASH; All participants N = 286; distal to carpus N = 256; proximal to carpus N = 30
QuickDASH; All participants N = 287; distal to carpus N = 257; proximal to carpus N = 30
