Eligibility
Inclusion criteria
Inclusion criteria: 1. Having at least one year experience with using a myo-electrical lower arm prosthesis with a passive wrist unit. Patients using an active, static wrist unit can join the project when not enough participants can be found who use a passive wrist unit; 2. Wearing the prosthesis for at least four hours a day; 3. The prosthetic hand has got one degree of freedom (opening and closing the hand); 4. Able to undergo tests and to fill out questionnaires.
Exclusion criteria

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| This study assesses the value and added value of a wrist that can be put in a flexion position and a wrist that can not only be put in a flexion position but can also move freely in a neutral position compared to a rigid wrist unit. | — |
Secondary
| Measure | Time frame |
|---|---|
| 1. Expectations about functionality of the new prosthetic wrist, compared to own prosthesis; 2. Joint angles (compensatory movements) during execution of several ADL (activities of daily living) tasks; 3. Pressure inside the socket of the prosthesis; 4. Functionality during usage of the prosthesis; 5. Satisfaction of the patient and information about benefits/disadvantages. | — |
