Table 3 Self-reported perception of mobility and changes in capacity and performance

From: The influence of powered prostheses on user perspectives, metabolics, and activity: a randomized crossover trial

 

User feedback regarding the powered prosthesis

Changes in outcome measures (+: increase from unpowered to powered)
