“…This proposal reflects the fundamental consideration that specific cognitive abilities are constituent aspects of cognition rather than isolated domains or, in other words, processes that are critically linked in the overall architecture of the brain [58]. The implementation of these scenarios includes a mechanism that adapts the difficulty automatically to the patient's capabilities using machine learning techniques [59], thereby addressing unique profiles of impairments and skills in a heterogeneous group of stroke patients. The algorithm adapts several task parameters, which reflect cognitive abilities, to the performance of the patient and hence adjusts the task's difficulty automatically.…”

Background: Current evidence for the effectiveness of post-stroke cognitive rehabilitation is weak, possibly due to two reasons. First, patients typically express cognitive deficits in several domains. Therapies focusing on specific cognitive deficits might not address their interrelated neurological nature. Second, co-occurring psychological problems are often neglected or not diagnosed, although post-stroke depression is common and related to cognitive deficits. This pilot trial aims to test a rehabilitation program in virtual reality that trains various cognitive domains in conjunction, by adapting to the patient's disability and while investigating the influence of comorbidities. Methods: Thirty community-dwelling stroke patients at the chronic stage and suffering from cognitive impairment performed 30 min of daily training for 6 weeks. The experimental group followed, so called, adaptive conjunctive cognitive training (ACCT) using RGS, whereas the control group solved standard cognitive tasks at home for an equivalent amount of time. A comprehensive test battery covering executive function, spatial awareness, attention, and memory as well as independence, depression, and motor impairment was applied at baseline, at 6 weeks and 18weeks follow-up. Results: At baseline, 75% of our sample had an impairment in more than one cognitive domain. The experimental group showed improvements in attention (χ 2 F (2) = 9.57, p < .01), spatial awareness (χ 2 F (2) = 11.23, p < .01) and generalized cognitive functioning (χ 2 F (2) = 15.5, p < .001). No significant change was seen in the executive function and memory domain. For the control group, no significant change over time was found. Further, they worsened in their depression level after treatment (T = 45, r = .72, p < .01) but returned to baseline at follow-up. The experimental group displayed a lower level of depression than the control group after treatment (Ws = 81.5, z = − 2.76, r = − .60, p < .01) and (Ws = 92, z = − 2.03, r = − .44, p < .05). Conclusions: ACCT positively influences attention and spatial awareness, as well as depressive mood in chronic stroke patients. Trial registration: The trial was registered prospectively at ClinicalTrials.gov (NCT02816008) on June 21, 2016.

“…The principle of embodied ideomotor training is integrated into a range of goal-oriented tasks, exercising different aspects of motor and cognitive function that have been shown to enhance retention of new motor schema inducing more substantial treatment effects (Timmermans et al, 2010). RGS individualizes training, where each trial of each session is customized to the capabilities of the user and the specific training objectives using machine-learning techniques (Nirme et al, 2011). The task considered here, Spheroids, consists in reaching, grasping, and releasing spheres into color-matched boxes (Cameirão et al, 2010).…”

2The impact of rehabilitation on post-stroke motor recovery and its dependency on the patient's 3 chronicity remain unclear. The existence and regularity of a, so called, proportional recovery rule 4 across a range of functional deficits and therapies supports the notion that functional interventions 5 have little or no impact beyond spontaneous recovery rates in a 'critical window of recovery' 6 which lasts from 3 to 6 months post-stroke. In this meta-analysis, we apply a bootstrap analysis 7 method to assess the overall impact of a specific VR-based rehabilitation protocol for the upper 8 extremities on a homogeneous sample of 219 individuals with hemiparesis at various stages 9 post stroke. Our analysis uncovers a precise gradient of sensitivity to treatment that expands 10 more than one year beyond the limits of the so-called 'critical window of recovery'. These findings 11 redefine the limits of the so-called 'critical window of recovery' and suggest that stroke-derived 12 plasticity mechanisms do facilitate functional recovery even at the chronic and late chronic stage. 13

Abstract. In this study, a Virtual Reality system for stroke rehabilitation was left in the homes of chronic stroke patients to monitor the progress of the patients after constant and extended use of the system. The frequency of use indicated that patients were able to use the system independently. We also found an improvement on the Chedoke Arm and Hand Activity Inventory (CAHAI) scale at the end of the treatment.
