Table 3. Relationship between QuickDASH and clinical measures of upper limb impairment after stratification of the sample using total mJOA scores.

	Mild N = 59		Moderate N = 57		Severe N = 31
	r	p	r	p	r	p
Quick DASH/GR-sens	-0.347	0.01	-0.102		-0.058
Quick DASH/GR-str	-0.574	<0.001	-0.361	0.005	-0.481	0.006
Quick DASH/GR-pp	0.285	0.038	0.043	0.029	0.072

mJOA score of: 17–15 = mild, 14–12 = moderate, less than 12 = severe [5]; GR-sens = GRASSP Sensation, GR-str = GRASSP Strength, GR-pp = GRASSP Prehension Performance; r = Pearson Correlation Coefficient; p = p-value. A significance level of p<0.01 was used.
