Table 4. Relationship between QuickDASH and clinical measures of upper limb impairment after stratification of sample using upper limb mJOA-UL scores.
| mJOA-UL | Normal (n = 8) | Mild (n = 71) | Moderate (n = 49) | Severe (n = 12) | ||||
|---|---|---|---|---|---|---|---|---|
| r | p | r | p | r | p | r | p | |
| Quick DASH/GR-sens | -0.037 | -0.226 | <0.001 | -0.367 | 0.009 | -0.276 | ||
| Quick DASH/GR-str | -0.798 | 0.01 | -0.355 | 0.002 | -0.416 | 0.002 | -0.741 | 0.005 |
| Quick DASH/GR-pp | -0.421 | 0.089 | 0.316 | 0.02 | 0.433 | AS | ||
mJOA-UL score of: 8 = normal, 6 or 7 = mild, 5 or 4 = moderate, 3–1 = severe; 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.
