Quantifying prosthetic gait deviation using simple outcome measures

Figure 1 Measured vs predicted gait deviation index for selected equation, constructed using a combination of six-minute walk distance, AM_C, t_stand and chronological age (adjusted R² = 90. 2; predictive R² = 86.2). AM_C: Over the past four weeks, rate your ability to walk up stairs when using your prosthesis; t_stand: Time taken to stand; GDI: Gait deviation index.
