Many American adults in today's society spend extended periods of time hunched over a computer or phone. This hunched position weakens the upper posterior muscles that support the shoulder and neck prompting muscle imbalance. Specifically, the lower trapezius and clavicle flexor muscles become too weak while the pectoral and upper trapezius muscles become too tight leading to the condition known as postural kyphosis or, more commonly, rounded shoulders. Our project aimed to design, build, and test a device able to treat and correct postural kyphosis through sensorimotor training. While the effectiveness of this device was determined through a short-term biomechanical validation processes, we recommend further testing to gather the long-term effects of use
