Figure 3: Relationship Between Reachable Workspace and ADLs.

Figure 3:

Box-and-whisker plots showing the distribution of total RSA (A) and above shoulder RSA (B) in 5 NeuroQoL questions related to proximal & shoulder items separating those that are fully independent (no difficulty) and those that are not (unable/much/some/little difficulty). (C) ROC curve for determining cutoff values for total RSA (cutoff = 0.70) for individuals who are independent (no difficulty) in performing the 5 proximal & shoulder items. (D) Above shoulder RSA (cutoff = 0.40) for individuals who are independent (no difficulty) in performing the 5 proximal & shoulder items. Dashed lines in (A) and (B) represent cutoffs for total and above shoulder RSA values, respectively. Cutoffs were used to determine reported sensitivity/specificity and positive predictive value/negative predictive values.
