Interventions
The participants will be fitted with two elastic bands. Each band is fitted with 8 equally spaced clinically used electrodes (Otto Bock 13E200=50). The first band is placed on the thickest part of the

Eligibility
Inclusion criteria
Inclusion criteria: The inclusion criteria for the participants are: individuals with acquired unilateral limb deficiency at the transradial level. The stump needs to be properly healed with sufficient reduction of stump oedema which can usually be expected 8 weeks after surgery. Participants should have a 2 cm broad region on the forearm with no scaring. Their understanding of the Dutch language needs to be sufficient to understand what they need to do in the experiment.

Exclusion criteria: Anyone who do not match the inclusion criteria

Primary
| Measure | Time frame |
|---|---|
| The EMG signals of forearm muscles will be measured from both limbs using the electrode bands. To compare EMG patterns during movement execution between conditions and affected / un-affected limb, we will compute three indexes: (1)SI (separability index): How distinct are EMG activity patterns for different movements? (2)RI (repeatability index): How similar are patterns of the same movement if repeated? (3)VI (variability index): How variable is each pattern over the time of one movement execution? | — |
