13. Results/Conclusions

14. Recommendations
Attaching the device to a rigid structure instead of the patients’ body
Design a shoulder harness to fully limit a patients’ ability to shrug
Design a left arm system
Work closely with a spring manufacturer to help fabricate a custom spring with a unique force output profile
