Introduction Cognitive impairment in multiple sclerosis (MS) can present as deficiencies in the speed at which information is processed, memory, the ability to plan and execute tasks (executive function), and attention. To investigate the potential impact of telerehabilitation- based task-specific training on cognitive function improvement in patients with Multiple Sclerosis (MS). Method The study design was an 8-week double-masked, randomized controlled trial involving 52 participants, who were randomly split into two groups. Specifically, Group A had telerehabilitation cognitive training through Physitrack processing speed exercises. The control Group B was given traditional CR intervention. Both groups sought to improve cognitive function and quality of life in MS patients through MoCA and MSIS assessment. Results Group A, with a mean age of 38±6.67 and Group B, which had a mean age of 30.96±6.61. They never had the technology, and they survived single. At baseline and in the 8th week, Group A had significantly higher scores on the MOCA compared to Group B; however, there was no significant difference between the two groups in the MSIS scores. Conclusion This study concluded that telerehabilitation group A had higher cognitive function than group B, which underwent traditional cognitive rehabilitation intervention.
