Neurological damage resulting from stroke often leads to hand impairment called "paresis". Current strategies for assessment and rehabilitation of hand paresis are simplistic and have limited effect on recovery. Simulation of real-world tasks using virtual reality (VR) and measurement of associated neural activity by functional magnetic resonance imaging (tMRI) have potential utility in research and clinical stroke applications. However, development of fMRI-compatible sensory feedback technology is required. This thesis describes initial development of a force feedback device for VR-fMRI. Experiments validated device performance in terms of force output, interaction bandwidth, transmission delay, and fMRI-compatibility. A subsequent VR-fMRI experiment involved six participants touching a virtual object. This experiment verified modulation of brain activity with force feedback vs. no force feedback in VR. Accordingly, this device may facilitate further experiments to clarify the effect of haptics in VR, and may be adapted for characterizing brain function and behaviour associated with hand paresis.
