Quantifying prosthetic gait deviation using simple outcome measures

Figure 2 Receiver operating characteristic curves for a range of measured cut-offs [65-85 (A-E), or 3. 5-1.5 (A-E) standard deviations (σ) away from the able-bodied mean] for the predictive equation comprised of six-minute walk distance, AM_C, t_stand and age. Also included in the bottom right cell are mean values and 95%CIs for AUC for each of the measured cut-offs. AM_C: Over the past four weeks, rate your ability to walk up stairs when using your prosthesis; t_stand: Time taken to stand; AUC: Area under the curve.
