Functionality of the upper limb is vital for performing Activities of Daily Living (ADLs) such as bathing, dressing, and eating. The goal of this project was to design, manufacture, test, and evaluate a shoulder mount to be used in conjunction with a powered, upper-limb orthosis. A prototype was developed that allows completion of all necessary ADLs, is user-friendly, and does not significantly increase the user’s body frame. On average, the device limits the user’s shoulder flexion and abduction by approximately 43% and 50%, respectively, and is reasonably adjustable to both male and female users in the 25th to 75th percentile range. The device is a viable candidate for further development and integration with an already patented wearable, powered, upper-limb orthosis.
