Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The objective of this study is to evaluate the efficacy of the Point Powered system as compared to the patient's standard-of-care treatment. This study will be a single subject crossover design where one group of 10 adult partial hand amputees will be evaluated on several metrics on their existing prosthetic treatment (Treatment 1) and the Point Powered system (Treatment 2) over a period of three months using standard two-site myoelectric control. Metrics include: in-clinic functional measures, subjective assessments, bilateral hand use, and prosthesis wear time.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Current/No Device

Baseline outcome measurements will be performed with subject's existing partial hand prosthetic treatment, as deemed standard-of-care by the patient's prosthetist. Device types include, but are not limited to, no prosthesis, passive prosthesis, passive positional prosthesis, body-powered prosthesis, myoelectric prosthesis, or other assistive device.

Group Type NO_INTERVENTION

No interventions assigned to this group

Point Powered

Outcome measurements will be performed after the subject has been fit with the Point Powered at 3 different points in time: immediately post-fitting, \~30 days post-fitting, and \~60 days post-fitting.

Group Type EXPERIMENTAL

Point Powered partial hand prosthetic system

Intervention Type DEVICE

The Point Powered system includes 1-4 3-joint mechatronic digits, low-profile EMG electrodes, a low-profile controller, and flexible batteries. These components will be integrated into a waterproof and dustproof packaging
