Outcome Measures

Primary Outcomes (2)

  • Kinematics data while performing the Pasta Box Task

    Utilizes motion capture hardware during prosthesis use and collects three dimensional angular kinematics, gaze behavior and performance during simulated tasks. Participants move a pasta box from the target on a side cart at the right side of the body onto a mid-height shelf target in front of them. Then they move the box from the mid-height shelf target to the high shelf target on the opposite side. Finally, they pick up the pasta box from the high shelf target and return it to the initial position. Each task can be subdivided into specific phases of reaching, grasping, transporting and releasing objects. By breaking down each task into movements, and each movement into specific phases (reach, grasp, transport, and release), the investigators can examine these components individually.

    After 6-week home trial

  • Kinematics data while performing the Cup Transfer Task

    Utilizes motion capture hardware during prosthesis use and collects three dimensional angular kinematics, gaze behavior and performance during simulated tasks. The Cup transfer task consists of moving two cups filled with beads (simulating being filled with liquid) over a partition and back again for a total of four object movements. The cups are deformable and will spill beads if grabbed too hard. Like in the Pasta task, participants start each trial with their hand in the home position and their eyes fixated on a centered motion capture marker. Each task can be subdivided into specific phases of reaching, grasping, transporting and releasing objects. By breaking down each task into movements, and each movement into specific phases (reach, grasp, transport, and release), the investigators can examine these components individually.

    After 6-week home trial

Secondary Outcomes (2)

  • Eye gaze data while performing the Pasta Box Task

    After 6 week home trial

  • Eye gaze data while performing the Cup Transfer Task

    After 6 week home trial

Study Arms (6)

Able-bodied participants

NO INTERVENTION

Participants without amputation were enrolled to collect normative data for system validation. Adhesive motion capture markers will be placed on both arms (upper arm, forearm, hand and finger tips), thoracic spine and sacrum. The participant wears a specialized headband/glasses with an attached camera for eye tracking. The participant will pick up and move objects of different shapes to and from various heights.

Transradial amputee participants

ACTIVE COMPARATOR

Individuals using their home prosthesis when available. Adhesive motion capture markers will be placed on both arms (upper arm, forearm, hand and finger tips), thoracic spine and sacrum. The participant will wear a headband with attached markers for eye tracking. The participant will pick up and move objects of different shapes to and from various heights.

Eligibility Criteria

Age18 Years - 70 Years
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • A unilateral upper limb amputation or absence below the elbow
  • Ability to use a myoelectric prosthesis
  • English Speaking

You may not qualify if:

  • 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 sufficient to 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 in order for the study to generate useable, reliable data.
  • 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
