Lower-limb amputation Q72.0 Q72.9 S78.1 S78.9 T13.6
Conditions
Interventions
Group 1: Patients with unilateral lower-limb transfemoral amputation wearing a prosthesis will be tested in two standard clinical balance tests (Berg-Balance-Scale: 14 different short mobility tasks
Timed-Up-and-Go-Test: simple mobility test of balancing ability). Furthermore, the changes of the center of pressure (CoP) and the synchronization of muscle activity (EMG measurements) will be measure

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| While participants are standing still on a force measurement platform, data will be obtained about the changes of the center of pressure in their feet and the synchronization of muscle activity. This data will be analysed to be able to compare the complexity of CoP adjustments in participants with lower-limb amputation and the control group. Additionally, amputees will get transcutaneous electrical surface stimulation to take a first step directing to an enahncement of balance control by restoring sensory feedback. | — |
Secondary
| Measure | Time frame |
|---|---|
| General body balance abilities of the participants will be assessed with two standard clinical mobility tests (Berg-Balance-Scale and Timed-Up-and-Go-Test). The results of these tests are in the following correlated with the results from the CoP measurements. | — |
