- Abstract:
Ischemic stroke survivors show cognitive impairments which often persist in the chronic phase after the event. Working memory impairments, in particular, have a large impact on instrumental activities of daily living and may predict poor cognitive recovery after ischemic stroke. Recent studies have indicated that performance on instrumental activities of daily living can be improved through computer-based working memory training. The goal of this study is to determine the effect of a computer-based working memory training on instrumental activities after ischemic stroke.

Intervention Overview
- Intervention:
The aim of this study is to is to determine the effect of a computer-based working memory training on instrumental activities after ischemic stroke. The intervention method is classified as an adaptive, intensive computerized working memory training program (Braining), developed by Professor Daniel Landinez Martinez at Universidad Católica Luis Amigo, Colombia. Both the adaptive and active control training groups will use the program approximately for 25 sessions of 50 minutes over 12 weeks.The training is considered adaptive which means that the difficulty level of the tasks increases during the sessions according to the individual level of mastering for each participant, making the patient work at their maximum capacity at all times. This is the core element of the hypothesized effectiveness of the intervention. The active control group will use a non-adaptive (fixed low-level training) version of the training program. The interface of both the active control and the training version is identical, but the difficulty level in the active control group version does not increase adaptively as the patient performance improves. The study involves two examinations at the following time points: baseline before training, retesting after training completion (3 months). Direct benefits include increasing functional independence: using a cellphone, taking his/her own medication, handling money, cooking, turn on/off the radio and T.V, walking around the house. Other indirect benefits include better quaility of life.
This trial has been approved by both Universidad San Buenaventura Research Ethics Comittee and by Instituto Neurológico de Colombia Institutional Review Board

Method Details
- Details of Evaluation Approach:
The proposed study is a randomized, controlled study that will include 30 patients diagnosed with ischemic stroke at a rehabilitation hospital. The participants will be randomized to either a training program or an active control group. The intervention is a computerized working memory training performed for 25 sessions of 50 minutes over 12 weeks. The active control group will train with an identical program in duration but is non-adaptive in the difficulty level of the tasks.The study involves two examinations at the following time points: baseline before training, retesting after training completion (3 months)
Key feasibility aims are to:
1. Describe socio-demographic and clinical features of an ischemic stroke patients sample
2. Measure performance in the Lawton-brody scale of instrumental activities of daily living and the working memory index before and after working memory training
3. Compare performance in the Lawton-brody scale of instrumental activities of daily living and the working memory index before and after working memory training in a sample of ischemic stroke patients.
Change History for Details of Evaluation ApproachChanged On Previous Value 10/19/2021 The proposed study is a randomized, controlled study that will include 54 patients diagnosed with ischemic stroke at a rehabilitation hospital.
