Focal Muscle Vibration (FMV) is receiving increasing attention as a tool for neuromuscular rehabilitation, particularly for stroke and spinal injury rehabilitation. Frequency characterization is a key factor in maximizing FMV related rehabilitation outcomes. We present a well characterized design of FMV device that can be used for various research applications. We also present an experimental scheme for characterizing the vibrational behavior of the device. Finally, we design a 3D printing casing to encapsulate the device and an electronic circuitry to control the vibration behavior of the device. The outcome of the project was a low-cost, user-friendly, wearable FMV device with a range of frequency settings specifically suited for neurorehabilitation.
