Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Participants will perform 2 tasks, sitting down and standing up, for two conditions, with stand-up support and without stand-up support, with variable seat-height. The main study parameter is defined as the lowest seat-height from which a participant is able to stand up without using their arms. | — |
Secondary
| Measure | Time frame |
|---|---|
| Degree of asymmetry between the ground reaction force, and the inverse kinematically calculated knee torque, of the sound limb and the prosthetic limb.The RMS of the Centre of Pressure (CoP) velocity during the initial 5 seconds after stand-up. This tests the standing stability right after the stand-up maneuver.Kinematic, motion capture, data of the lower extremity. | — |
