Summary

Liberating Technologies, Inc. (LTI) has developed a dexterous prosthetic fingertip that will be fit onto an i-Digits™ partial hand prosthesis and allow for an additional fine grasp. The device will interface with research participants' existing prostheses and use the same control strategy that is used for their everyday use. Each participant's prosthesis will be restored to their original configuration by the end of their testing period.

Eligibility Criteria

Inclusion Criteria

Must have an upper limb partial hand absence.
Must be new or current i-Digits prosthesis users.
Must have an absent index finger at minimum.
Must be able to understand spoken and written English in order to be properly consented and provide feedback to the study personnel.
Must be willing and able to complete outlined tasks and provide feedback on the intervention.

Exclusion Criteria

The risks to pregnant women and fetuses are unknown and therefore pregnant women should not participate in the study.
