Adults with an acquired amputation or congenital deficiency at the transradial level (including wrist disarticulation) with sufficient surface electromyography (sEMG) signals for using a myoelectric prosthesis. And a control group of able-bodied participants, to establish baseline values.
Conditions
Interventions
All groups except for the able bodied reference group will go through a similar training- and testing scheme. This training- and testing scheme will take place over the course of ten separate days. On

Eligibility
Inclusion criteria
Inclusion criteria: Inclusion criteria are: - 18 years of age or older - Upper limb deficiency at transradial or wrist level - Unilateral limb deficiency - Experience with myo-electric prosthesis - No experience with more than one of the control types that will be examined
Exclusion criteria
Exclusion criteria: Individuals that are younger than 18 years of age and/or have experience with both machine learning control and direct control will be excluded. Furthermore, individuals with an upper limb deficiency at another level than transradial or wrist level will not be included. In addition individuals with an amputation or congenital defects of both hands will be excluded. Potential subjects for the able-bodied control group will be excluded if they have any musculoskeletal health issues or if they are younger than 18 years of age.
