“…Subjects were assessed on components of sensory, motor, and cognitive function using 4 standardized tasks that have been previously described elsewhere. Visually guided reaching (VGR) assesses visuomotor abilities by having participants perform center‐out reaching 28. Position matching (PM) is a test of proprioception (position sense), in which the robot moves the stroke‐affected arm to 1 of 9 locations, and the subject is instructed to move their other arm to the mirror‐image location with vision occluded 29, 30.…”

BackgroundUnderstanding how the size of acute lesions and white matter hyperintensities (WMH) impact stroke recovery can improve our ability to predict outcomes and tailor treatments. The aim of this exploratory study was to investigate the role of acute lesion volume and WMH volume on longitudinal recovery of specific sensory, motor, and cognitive impairments after stroke using robotic and clinical measures.Methods and ResultsEighty‐two individuals were assessed at 1, 6, 12, and 26 weeks poststroke with robotic tasks and commonly used clinical measures. The volumes of acute lesions and WMH were measured on fluid‐attenuated inversion recovery images. Linear mixed models were used to investigate the role of acute lesions and WMH on parameters derived from the robotic tasks and clinical measures. Regression analysis determined the added value of acute lesion and WMH volumes along with measures of initial performance to predict outcomes at 6 months. Acute lesion volume has widespread effects on sensory, motor, and overall functional recovery poststroke. The impact of WMH was specific to cognitive impairments. Apart from the robotic position sense task, neither lesion volume nor WMH measure had significant ability to predict outcomes at 6 months over using initial impairment as measured by robotic assessments alone.ConclusionsWhile acute lesion volume and WMH may impact different impairments poststroke, their clinical utility in predicting outcomes at 6 months poststroke is limited.

“…Instead, these longlatency reflexes represent rapid motor responses that can be modified based on behavioral context and are thought to provide a crucial part of how one generates highly coordinated voluntary motor actions [20]. Subjects with stroke can also show subtle yet measurable differences in performance such as differences in reaction time during reaching between their paretic and nonparetic limbs [53]. Easily and accurately quantifying these features of the sensorimotor system with a standard clinical examination is nearly impossible.…”

“…Reaching performance in this task, however, is highly correlated with ADL scores such as FIM [59][60]. Figure 1 illustrates the spatial pattern of hand movements for a control and two subjects with stroke [53]. One of the key advantages of robot-based assessments is that a wealth of information can be gathered during a single behavior.…”

“…Two studies recently used robots to quantify the ability of subjects with stroke to make visually guided reaching movements [53,59]. This task requires the individual to maintain the hand at an initial visual target, then identify the onset and location of another visual stimuli, and then initiate and complete a movement to this second spatial goal.…”

Abstract-Robotic technologies have profoundly affected the identification of fundamental properties of brain function. This success is attributable to robots being able to control the position of or forces applied to limbs, and their inherent ability to easily, objectively, and reliably quantify sensorimotor behavior. Our general hypothesis is that these same attributes make robotic technologies ideal for clinically assessing sensory, motor, and cognitive impairments in stroke and other neurological disorders. Further, they provide opportunities for novel therapeutic strategies. The present opinionated review describes how robotic technologies combined with virtual/augmented reality systems can support a broad range of behavioral tasks to objectively quantify brain function. This information could potentially be used to provide more accurate diagnostic and prognostic information than is available from current clinical assessment techniques. The review also highlights the potential benefits of robots to provide upper-limb therapy. Although the capital cost of these technologies is substantial, it pales in comparison with the potential cost reductions to the overall healthcare system that improved assessment and therapeutic interventions offer.

“…Each target was presented once in a randomized block and eight blocks were collected. The full methods for this technique and evaluation of its reliability have been previously described [9]. Nine parameters were evaluated: 1) postural speed (PS) (m/s) is the mean hand speed for 500 ms before peripheral target illumination.…”

Assessment of Upper-Limb Sensorimotor Function of Subacute Stroke Patients Using Visually Guided Reaching

Abstract: Robotic technology using a visually guided reaching task can provide reliable information with greater sensitivity about a patient's sensorimotor impairments following stroke than a standard clinical assessment scale.
