Agenda

● Motivation ● Design Process Overview ● Initial ideas and prototype ● Final Prototype

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

Design Goals

How can we help arthrogryposis patients of Shriner’s Hospital dress themselves more easily?

Ideating ● Three stages of dressing

Criteria examined: 1) Safety 2) Ease of Use 3) Cost 4) Feasibility 5) Portability 6) Adjustability

Potential Solutions

Elastic Bands

Vertical Frame

Hip Lift

Initial Prototype

Prototype Testing

Change of Direction User Interview with arthrogryposis patient at Shriner’s Hospital for Children:

● 7 year old ● Limited motion in elbows and hands ● Possible horizontal motion along the waist● Difficulty with buttons and zippers on pants ● Currently has device made by OT to put on buttons but has difficulty in the final

step of putting the button through

How can we help our 7-seven-old patient have an easier time buttoning his pants?

Prototypes 2 & 3

Final Prototype

Part A Part B

User Manual1. Loop Part A of the device around itself through the buttonhole2. Push Part B of the device through the buttonhole and hook onto the button3. Tighten the hook around the button and twist Part B until the buttonhole opens4. Pull Part A and and Part B away from each other until the button goes through the

buttonhole 5. Remove Part A by undoing the loop and Part B by pushing the other way
