Background on Arthrogryposis● Arthrogryposis is a genetic condition that causes congenital joint contractures● A large majority, 84%, have every joint affected by the condition ● Impacts 750,000 people in the US alone● Performing even minor tasks can be a major undertaking and require assistive devices

Why Compact Dressing? ● Dressing can be a big hardship for people with arthrogryposis● Not many assistive devices available on the market for dressing● Available tools often aren't built to:
○ Range of motion○ Gripping abilities of patients
● Open source solutions unavailable● Not being able to dress oneself can be very detrimental to patient's mental health
