This study proposes a design for the interface circuitry between an SEMG-EEG; actuated Upper Extremity (UE) Orthosis and a PC or data acquisition system (DAQ). It is part of a research project which aims to develop a Unified Platform for accelerated recovery of stroke patients using the EEG-SEMG actuated UE Orthosis. The design of the interface between the UE orthosis and a PC / DAQ is a critical link in the successfu1 operation of the unified platform. Most applications involving processing of SEMG and EEG signals use commercially available devices for signal acquisition. However these devices could not be easily integrated into a Unified Platform because they suffer from a few serious drawbacks such as: 1) Recording multiple types of bio-potentials (eg. EEG, EMG, ECG, etc.) 2) Lack portability due to large size 3) Complex operation. 4) High Cost. 5) Proprietary software and limited support for third-party application development. The design proposed in this project tackles these issues by providing a versatile EEG- SEMG acquisition solution which is low-cost yet compact and convenient to operate. The widely used NI LabView (v8.0) was chosen as a software development platform to enable faster application development while ensuring the easy availability of programming resources and support.
