Change of cognitive functions after stroke with rehabilitation systems

Abstract

The objective of this study is to assess and compare the effect of applying a computerised cognitive training programme and virtual environment rehabilitation system on cognitive functions in patients after a stroke. Methods. A controlled trial included 121 persons referred to second stage rehabilitation. The subjects were differentiated into three impact groups by a single blinded trial. Results. The trial revealed that cognitive functions improved in all patient groups (p<0.001). A paired comparison analysis of all groups demonstrated a tendency for cognitive functions, evaluated by the MoCA–LT test, to be more strongly improved in patients who practised a computerised cognitive training programme during their OT sessions than those who did not (p=0.054). Conclusions. The final outcome of the trial was that cognitive functions significantly improved in patients who practised computerised cognitive training programmes or virtual environment rehabilitation systems, compared to those participants who only had occupational therapy sessions.

Impact of Virtual Reality-Based Therapies on Cognition and Mental Health of Stroke Patients: Systematic Review and Meta-analysis

“…Sample sizes ranged from 18 to 145, for a total of 894 patients with stroke. In total, 11 (47.8%) of the 23 trials were conducted in Korea [34,38,[42][43][44][45][46][47][48][49][50], 3 (13%) in Portugal [51][52][53], 2 (8.7%) in Spain [54,55], 2 in China [36,37], 2 in Australia [56,57], and 1 (4.3%) each in Lithuania [58], Brazil [59] and Turkey [60].…”

“…Regarding the types of VR-based therapies, 16 (69.6%) trials administered VR as a singular session [36][37][38]44,45,[47][48][49]51,52,[54][55][56][57]59,60], 5 (21.7%) trials were categorized as having used VR-based therapies plus occupational therapy [43,46,50,53,58], and 2 trials as having used VR-based therapies plus computer-assisted cognitive rehabilitation [34,42]. The frequency and duration of VR exposure varied considerably between trials.…”

“…In our review, the duration of VR-based therapies ranged from 3 to 10 weeks, with the majority being 4 weeks, and the frequency of intervention varied from 2 to 5 times per week. The control group underwent conventional rehabilitation therapy [36][37][38]44,47,48,51,54,56,57,59] or other support interventions such as occupational therapy [43,45,46,49,50,55,58], computer-assisted cognitive rehabilitation [34,42], and other rehabilitation therapies [52,53,60]. [34,45,49,51], and the Loewenstein Occupational Therapy Cognitive Assessment (LOTCA) [38,42].…”

Cognitive Impairment and Its Impact on Quality of Life in Rural Indian Female after Stroke: A Cross Sectional Study Protocol

“…Cognitive impairment affects inadequate ability to focus on the job, recall, understand, prepare, use knowledge, initiate and stop the operation and solve problem. A stroke impaired cognitive function including focus, memory, vocabulary, executive function, perception and orientation of space 4 .The word cognitive impairment post-stroke is used to describe both mild cognitive impairment and dementia that either occurs 3-6 months after stroke incident 5 .In addition, An approximate 16.9 million stroke cases occurred globally in 2010 6 .…”

The Effects of Self-Efficacy on Cognitive Function in Patients with Acute Stroke: Verification of the Medicating Effect of Family Support

“…Family support and self-efficacy have been individually identified in a small number of studies as factors affecting cognitive function in stroke patients, but neither have been verified with respect to the mediating effects of factors that can maximize patients' internal factors [9,10]. Studies of these factors can help develop effective nursing interventions for disease treatment by identifying various applicable surrounding support factors and by strengthening the internal factors of individuals required for the long-term treatment of stroke patients [11]. In this study, we therefore aimed to provide basic data to identify the degree of self-efficacy and cognitive function of stroke patients and empirically verified the mediating effect of family support on the relationship between self-efficacy and cognitive function.…”
