Design outcomes
Primary
| Measure | Time frame |
|---|---|
| If the innervation zone can indeed be reliably located using HDsEMG: the distance [mm] between this location and the location as estimated using the bony landmark method. | — |
Secondary
| Measure | Time frame |
|---|---|
| Variability in innervation zone location as a function of test condition, i.e. of elbow and wrist joint angles, level of isometric contraction and stimulation method (i.e. voluntary contraction on various levels of force, reflex induction by an external stretching force, or electrical stimulation). | — |
