Objective Robot-Based Measures of Cognitive and Motor Function in Patients with Stroke and HIV

The effects of HIV-related cognitive impairment on motor recovery after stroke are poorly understood. A barrier to understanding this is quantitative measures to assess both cognitive and motor function in a rehabilitation setting. In this paper, we present preliminary data collected from a sample of stroke and HIV-stroke subjects on robot-based metrics that relate to cognitive and motor clinical scores. Additionally, we explore representing the dominant and non-dominant limb performance in a single laterality index metric. Our results show that this is a feasible approach to stratifying stroke and HIV-stroke patients with varying levels of cognitive and motor impairment by functional level to develop more targeted neurorehabilitation strategies in the future.
