Effects of Dual-Task Training in People With Multiple Sclerosis

BBS, evaluates daily activities including static sitting and standing balance, as well as transfers, turning, and picking up objects from the ground, in 14 items.Scoring is given as 0-4. It scores from 4 (normal performance) to 0 (not able to do the movement) according to the person's ability to do what is asked of them safely and independently. The total score is 56 points. 0-20 indicates high risk, 21-40 indicates medium risk, and 41-64 indicates low risk.

It is a frequently used test that evaluates functional mobility and dynamic balance. At the beginning of the test, individuals sit in a chair. A distance of 3 m is set in front of the patient. With the start command, the patient gets up from his seat and walks 3 m, turns around and walks back and sits. With the start command, the time until the moment of sitting on the chair is recorded in seconds.Shorter duration indicates better functional mobility.

Tetrax (Sunlight Medical Ltd, Israel) computerized posturography device consists of a platform system where data is collected, a computer and software system where data is processed and integrated. Participants will stand on the platform system in 8 different condition. Tetrax will be used to measure static balance and fall risk.

MSWS-12 is a 12-item scale evaluating the effect of MS on person's walking ability. MSWS-12 is scored between 12-54. Higher scores indicate more negatively affected walking ability.

The scale consists of 9 questions and each question is graded over 7 points.FSI is scored between 0-63. Higher scores indicate more fatigue.

BICAMS includes Symbol Digit Modalities Test (SDMT), California Verbal Learning Test II (CVLT-II) and Brief Visuospatial Memory Test-Revised (BVMT-R). The total score is determined by summing the scores of the 3 tests. Battery will be used to evaluate cognitive function. Higher scores indicate better cognitive function.

This test calculates the unassisted walking speed of individuals at a distance of 10 meters. In this test, the person will be asked to walk at their normal pace in a pre-measured 10 meter area.

Dual-Task performance will be measured with TUG-cognitive and 10MWT-motor. In TUG-cognitive,patient will be counting down by three from a number between 100 and 200 while performing Timed-Up and Go test. In 10MWT-motor,patient will be carrying a tray with 3 water filled 200 ml plastic glasses while walking a 10 m distance.Time will be measured. Longer time to complete task indicates lower dual-task performance.

The Dual Task Questionnaire assesses the frequency of difficulties experienced by individuals with neurological injury or disease during activities of daily living that involve dual tasks. DTQ is scored between 0-40. Higher scores indicate more frequent dual-task difficulties.
