Optimize Pattern Recognition Control of Powered Upper Limb Prosthesis
Evaluation of Functional Performance of Persons With Limb Differences to Optimize Pattern Recognition Control of Powered Upper Limb Prosthesis
This study is focused on optimizing methods for controlling upper-limb myoelectric prosthetic arms. If you are enrolled in this study you would be expected to visit one of the research sites for approximately 5 in-lab visits lasting about 4 hours. These visits are expected to happen within a 5-week period but may take longer depending on scheduling availability. During these visits you will be completing basic tasks similar to your everyday actions using a prosthetic arm that is provided for you.

Beskrivelse
Inclusion Criteria:
- Aged 18 years or older
- Unilateral transradial level limb difference
- Current or past user of myo-electric controlled prostheses
- Six months or more post-amputation
- Have adequate limb length such that a wrist rotation device can fit in the check socket
- Have adequate limb length and diameter such that at least 9 channels of electrodes fit without cross pairing
- Well-fitting socket as determined by a Socket-Comfort Score of 6 or above
- Capable of wearing and operating a prosthesis with a wrist rotator and multi-articulating hand
- Capable of understanding and following multi-step instructions and completing the tasks as described
- English speaking
Exclusion Criteria:
- Significant new injury that would prevent use of a prosthesis: The ability to consistently wear a prosthesis and perform activities of daily living and specific performance tasks is necessary to evaluate the relative benefits of the interventions.
- Cognitive impairment that would adversely affect understanding of or compliance with study requirements, ability to communicate experiences, or ability to give informed consent: The ability to understand and comply with requirements of the study is essential for the study to generate useable, reliable data. The ability to obtain relevant user feedback through questionnaires and informal discussion adds significant value to this study.
- Significant other comorbidity: Any other medical issues or injuries that would preclude completion of the study, use of the prostheses, or that would otherwise prevent acquisition of useable data by researchers.
- Pregnant participants as risk to pregnant individuals, embryos, or fetuses are not understood.
