Table 5.
Sit-to-stand and stand-to-sit deviations, user instructions, and prosthesis parameter adjustments.
| Mode | Deviation | User instruction | Prosthesis setting |
|---|---|---|---|
| Stand to sit | Unable to initiate sitting | Cue for active hip flexion and equal weight bearing between limbs for increased load onto the prosthesis | Decrease axial load threshold |
| Inadequate support during sitting | N/A | Increase or decrease knee damping to provide more or less support, respectively | |
| Sit to stand | Unable to initiate standing | Cue to increase forward trunk position and load onto the prosthesis | Decrease axial load threshold to initiate knee extension power |
| Inadequate support or power during standing | Cue for equal weight bearing between limbs for increased load onto the prosthesis | Increase stance phase knee stiffness for improved support and power into knee extension |
