**1. Proposed**  **minimum wi**  **dth of 30 in. prov**  **ides sufficient space for**  **almost all indiv**  **iduals in sample based**  **on static measurements. Could**  **be reduced to 28”**  **and still**  **accommodate 95 %.**  **2. Width**  **of 30” w**  **ould also accommodate the shoulder breadth of most**  **indiv iduals.**  **Reducing wi**  **dth to**  **28” wo**  **uld still**  **accommodate 95% o** **f sample.**  **3. Increasing**  **minimum wi**  **dth is recommended**  **for indiv iduals**  **that are morbidly**

# Considerations

• **What Data sets to use?**

• **What gender and percentile w ould**  **be a good benchmark?** 

• **How m**  **uch to extrapolate from “static” anthropometric dimensions?** 

• **Balance betw een**  **the use of different equipment features?** 

• **Multiple recommendations?**
