Cognitive Motor Interference During Dual Tasking With Movements of the Upper Limb in Persons With Multiple Sclerosis
Abstract
Multiple sclerosis (MS) is a chronic, inflammatory, neurodegenerative disorder of the central nervous system, with more than 2.5 million people in the world. It is the most non-traumatic cause of disability in young and middle-aged adults.
Because the lesions are spread in the brains, there is a variety of symptoms. The most common symptom is the typical motor dysfunction. 66% of persons with MS, and even 81% of them after 15 years, have problems with movements in one or both upper extremities.
Also, 40 untill 70% of persons with Multiple Sclerosis have cognitive impairment. Although they are less visible, they can have a major determining influence on social or work-related domains. The most frequent cognitive dysfunctions are sustained attention, reduced speed of information processing, impaired memory and limited executive functions.
When a combination, of motor and cognitive task, is asked, the execution of these tasks could be difficult with the foregoing in mind. For example problems during chatting while cooking, typing a report at a meeting or watching television while ironing.
The dual-task paradigm assumes that the attention should be divided between two simultaneous tasks. A dual task cost (DTC) is a restriction in performance on each task, compared whit the separate task versus simultaneously.
Research on dual tasking with persons with MS has already studied extensively, but not specific on the upper limb. In 2015 Learmonth, Pilutti and Motl published an primary…
How strong is the evidence?
Evidence Hub reads this as a clinical trial, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 68 participants or records.
