Orthotic Research Initiative for Outcomes aNalysis (ORION I): predictors of PROMIS PF for stroke survivors seeking orthotic intervention

Figures & data

Figure 1. Distribution of self-reported physical function T-score for the sample. Mean (SD) = 30.8 (6.5). Mean (SD) T-score for physical function for the general U.S. population = 50 (10). Higher T-scores indicate better physical function.
