Table 1 Definition of the aim categories
Aim category | Definition |
|---|---|
Subjective evaluation | Subjective aims regarding participant’s or physiotherapist’s perspective after user-trials, like an interview |
Mobility | Aims regarding mobility, for example walking ability or gait assessment |
Energy consumption of participant | Aims regarding metabolic cost and energy consumption of participants when walking with the prosthesis prototype |
Energy handling of prosthesis prototype | Aims regarding energy handling of the prosthesis prototype, for example battery life, battery recharge during gait, or energy efficiency |
Prosthesis control | Aims regarding the control algorithm of the prosthesis prototype, for example providing swing or stance phase control, control simplicity, intent recognition, algorithm accuracy, or delays |
Effect of powered prosthesis | Aims including the delivery and output of the required power of the prosthesis, for example power generation similar to an anatomical joint, providing power during climbing the stairs, or inject small amounts of power during the swing phase |
Prototype characteristics | Aims on the characteristics and properties of the prosthesis prototype, for example device weight, size, cultural, and aesthetic aspects, or production cost |
