The purpose of this study is to determine the utility of a performance measure for the dual-task of gait and considering people with multiple sclerosis have both cognitive and motor problems, the secondary aim of this study is to determine the effectiveness of a gait-specific dual-tasking intervention for ambulatory individuals with multiple sclerosis.
A total target sample size of 40 adults with MS and 40 adults without MS will be recruited. The 40 adults without MS will undergo the two baseline testing sessions only for the first phase of the study. 20 of those individuals with MS will be randomly selected to undergo the intervention phase of the study. The research design will include two groups, the intervention and control group. Both groups will undergo a screening process, two baseline testing sessions, and be randomly assigned to one of the two groups. The duration of the study is 6 weeks in length for a total of 18 training sessions. The intervention group participants will undergo gait training with a specific concomitant cognitive task (dual-task) for a total walking time of 20 minutes and with rest breaks the total session time is \~60 minutes with a physical therapist. The control group will undergo gait training, but without the cognitive task. Feedback from the therapist will be provided to each participant concerning gait mechanics and ways to improve gait regardless of group membership. Outcome measures data will be collected twice at baseline, once at mid-intervention, once at post-intervention, and once at one-month follow-up.

During the training sessions, you will participate in gait training with a physical therapist (PT). You will be asked to walk in 2-minute bouts and you will be provided with adequate rest breaks to help manage your fatigue levels. In addition to performing the gait training activities, you will be asked to perform thinking tasks at the same time. These pre-recorded questions or prompts will be provided to you through headphones and a portable music player. This is to help ensure that the PT is able to focus on giving you feedback about your walking ability and answers to the thinking tasks, and on your safety. At the end of each session, you will have walked for a total walking time of 20 minutes.

RECRUITINGChange in Walking and Remembering Test
Measures dual-task cost of gait and a titrated forward digit span cognitive task, measured as a percentage.
Time frame: Week 1, Week 2, Week 5, Week 8, Week 12
Change in 2-Minute Walk Test
Measures total distance walked by an individual within a 2-minute time period. Measures distance in feet and meters.
Time frame: Week 1, Week 2, Week 5, Week 8, Week 12
Change in 12-Item Multiple Sclerosis Walking Scale
Measures self-reported and self-perceived walking disability due to MS in the past 2 weeks. The 12-Item Multiple Sclerosis Walking Scale consists of 12 questions. Each question is rated on a Likert scale from 1 (not at all) to 5 (extremely). The items are scored for a minimum score possible of 12 or a maximal score of 60. This summed score is then divided by 60 and the resulting percentage is interpreted. The scale's final percentage score can range from a minimum of 20% (minimal impact of MS on walking, good outcome) to a maximum of 100% (significant impact of MS on walking, poor outcome).
Time frame: Week 1, Week 2, Week 5, Week 8, Week 12
Change in Fatigue Scale for Motor and Cognitive Functions
Measures self-reported physical and mental fatigue levels by the patient with MS. The Fatigue Scale for Motor and Cognitive Functions measures both the motor and cognitive domains of fatigue. The scale consists of 20 total items: 10 items related to motor fatigue and 10 items related to cognitive fatigue. Each item is rated on a Likert scale from 1 (does not apply at all) to 5 (applies completely). The scale items can be summed for a total score (ranging from 20 to 100) or subscales can be summed and interpreted with each subscale ranging from a minimum of 10 points to a maximal 50 points. Higher values in the total score or in the subscale scores indicate worse fatigue and poorer quality of life due to fatigue.

Change in Gait Speed
Changes in gait speed (m/s) will be measured for a 10-meter distance. This will be measured by the Protokinetics ZenoWalkway.
Time frame: Week 1, Week 2, Week 5, Week 8, Week 12
Change in Gait Cadence
Changes in gait cadence (steps/min) will be measured for a 10-meter distance. This will be measured by the Protokinetics ZenoWalkway.
Time frame: Week 1, Week 2, Week 5, Week 8, Week 12
Change in Step Length
Changes in step length (cm) will be measured for a 10-meter distance. This will be measured by the Protokinetics ZenoWalkway.
