What is Spinal Muscular Atrophy (SMA)? Genetic disease Attacks motor neurons in spinal cord Leads to muscle weakness and atrophy #1 genetic killer of children < age 2 (95% mortality) SMA type II ~ age 20 = 77%

Why design for SMA? Recent breakthroughs in research –SMN1 and SMN2 genes –NIH and NINDS massive funding –Research (JHU, Columbia, MIT, Stanford) Lots of new therapy treatments BUT…. Current evaluations are subjective, inaccurate, and insensitive. Clinicians Need: Robust and quantitative motion capture and analysis system

Constraints and Specifications ROBUSTNESS ERGONOMICS SAFETY RELIABILITY EASE OF USE / CONVENIENCE COST Variety of Patients Intentional Movements Limited Weight Natural Movements Constant arm support Repeatability Not overly sensitive Calibration Minimal External Cables Portable Minimal Training Balance Cost and Necessity Max Cost: Gaming Console Reduce Friction

In a Nutshell… SMA is a deadly genetic disease Many new therapies coming out Need for a robust, quantitative motion capture and analysis system Current devices are either very advanced or too simple We propose: –a device to capture & evaluate 2D movements on frictionless, horizontal plane
