Study summary

This study asks individuals with upper limb absence to use a new hand prosthesis, and compare it's performance to their own hand prosthesis

Inclusion Criteria: * Multi-articulating hand experience * At least 18 years old * Transradial, acquired amputation or congenital upper limb absence * Unilateral upper limb absence preferred Good socket comfort in own prosthesis (\>/= 6 on Hanspal socket comfort score) Exclusion Criteria: * Any health conditions that pose a risk to participation in study events (in the opinion of the Investigator), e.g. Visual impairment; Cognitive impairment * Cognitively unable to provide informed consent or comply with the study procedures

Primary outcome measure(s)

  • Grip Accuracy — At baseline and each post-treatment visit (x3 visits over 12 weeks)
    Functional observer rated test of ability to perform grips. This test assesses the feasibility that the device can be used as a reliable hand prosthesis when operated by the intended use population. An observer rates the successful achievement of the prompted outcome on a 0-3 scale (0= no output, 3= output achieved without error). The four grips (hand open, hand close, thumb rotation to palm, thumb rotation away from palm) are repeated x3, resulting in a minimum summary score of 0 or a maximum summary score of 36.
