The first aim of this project is to investigate the effects of different high-tech neurorehabilitation interventions (cognitive, motor, and combined cognitive-motor) on both cognitive and motor disability outcomes in people with multiple sclerosis (MS).
The second aim is to identify the cognitive and motor profiles of MS patients who benefit the most from either the combined cognitive-motor rehabilitation intervention or the isolated cognitive or motor treatments.

| Motor rehabilitation: MG group | Device | 60 minutes of robot-assisted gait training with the G-EO System |
|
| Combined rehabilitation: CbG group | Device | 30 minutes of cognitive training with a computerized device + 30 minutes of robot-assisted gait training with the G-EO System. To mitigate the effects of fatigue in sequential training, the patients included in this group will undergo the cognitive (treatment CG) and motor (treatment MG) sessions in a counterbalanced order (half of the participants will follow the CG-MG sequence, and the other half will follow the MG-CG sequence). Five-minute breaks will be provided between the cognitive and motor sessions. |

| The test is administered before the treatment, then after eight weeks of treatment, and finally two months after the end of the treatmen |
| The Stroop Test (ST) | The Stroop Test (ST), which evaluates attention and the ability to inhibit automatic responses. The Stroop effect is evaluated by computing a time interference effect (based on execution time) and an error interference effect (based on number of errors). | The test is administered before the treatment, then after eight weeks of treatment, and finally two months after the end of the treatmen |
| Trail Making Test (TMT) | The Trail Making Test (TMT), which consists of two parts: the TMT-A, used as a measure of psychomotor speed and visual search/attention skills, and the TMT-B, used as a measure of attentional set-shifting and mental flexibility. Time needed to complete the tasks is recorded. | The test is administered before the treatment, then after eight weeks of treatment, and finally two months after the end of the treatmen |
| The Verbal Fluency Test (VF) | The Verbal Fluency Test (VF), which is composed of 3 subtests: the Phonemic Fluency, the Semantic Fluency, and the Phonemic/Semantic Alternate Fluency test. For each trial, the number of correct words generated in 60 sec is recorded. Performance score in each subtest is the sum of the correct words generated in all trials. | The test is administered before the treatment, then after eight weeks of treatment, and finally two months after the end of the treatmen |
| The Modified Five Point Test (MFPT) | The Modified Five Point Test (MFPT), which is a measure of figural fluency assessing the ability to initiate mental productivity and self-monitoring during a visual-spatial task. Performance is assessed by scoring the total number of correct and unique designs generated in 3 min (UDs), and the total number of UDs produced into strategies (CSs). | The test is administered before the treatment, then after eight weeks of treatment, and finally two months after the end of the treatmen |
| Test of Attentional Performance (TAP; version 2.3.1) | The Test of Attentional Performance (TAP; version 2.3.1), which evaluates different aspects of attention; in particular, we will administer a Go/No-Go task, which examines the ability to perform an appropriate response under time pressure and to simultaneously inhibit an automatic behavioral response triggered by an external stimulus. | The test is administered before the treatment, then after eight weeks of treatment, and finally two months after the end of the treatmen |
| N-Back task | The N-Back task be made up of a sequence of stimuli, and the task consists of indicating when the current stimulus matches the one from n steps earlier in the sequence. The load factor n can be adjusted to increase the task difficulty. We will administer the visual N-Back available from a computerized device. | The test is administered before the treatment, then after eight weeks of treatment, and finally two months after the end of the treatmen |
| Time up and Go (TUG) | Time up and Go (TUG) will be administered to assess functional mobility of patients. In this test, patients have to stand up, walk 3 meters, turn around, walk back, and sit down. The time taken to complete the test is correlated with the level of functional mobility. Patients can perform the TUG also under a dual task condition in which they are required to count backwards from a randomly selected number between 20 and 100 while walking (TUG-COG). TUG-COG is considered a cognitive task because it investigates dual task ability. The TUG is a good general indicator of locomotor function, but the timed global performance does not provide any information regarding the mechanisms underlying the patient's disabilities and specific problems relating to each sub-task are not highlighted. | The test is administered before the treatment, then after eight weeks of treatment, and finally two months after the end of the treatmen |
| eight-infrared camera system (sampling frequency: 60-120 fps) with the VICON Vero 2.2 motion analysis system (Vicon Motion Analysis System Ltd), | to specifically assess characteristics of gait, we will carry out gait analysis, which will be performed using an eight-infrared camera (sampling frequency of 60-120 fps) VICON Vero 2.2 motion analysis system (Vicon Motion Analysis System Ltd) synchronized with a two AMTI force plate. According to the Davis protocol, 16 reflective markers (14 mm diameter) will be positioned on the seventh cervical vertebra, the left and right anterior superior iliac spines (ASIS), the sacrum, the left and right mid-thighs, the left and right lateral femur condyles, the left and right mid-shanks, the left and right lateral malleoli, the dorsal aspect of the left and right feet (between the second and the third metatarsal head) and on the left and right calcanea [46]. Two analogue cameras will be integrated into the system and aligned with the sagittal and coronal planes. Gait cycle events (toe off and initial foot contact) will be defined automatically, using Vicon Clinical Manager software. | The test is administered before the treatment, then after eight weeks of treatment, and finally two months after the end of the treatmen |
| Modified Fatigue Impact Scale (MFIS) | To evaluate the patients' fatigue we will provide the Modified Fatigue Impact Scale (MFIS), a 21-items shortened version of the 40-items Fatigue Impact Scale. Although no basic analyses of the MFIS have been published, it has been used in clinical practice and several clinical trials and intervention studies | The test is administered before the treatment, then after eight weeks of treatment, and finally two months after the end of the treatmen |
| The Multiple Sclerosis Quality of Life-29 (MSQOL-29) | The Multiple Sclerosis Quality of Life-29 (MSQOL-29), the 29-items shortened version of the MSQOL-54, is a 29-item validated structured self-report questionnaire evaluating generic and MS-specific domains of health-related quality of life (QoL) in 7 multi-item subscales and 4 single-item subscales. Subscale scores are obtained by averaging the items within subscale and transforming the mean scores linearly to 0 to 100 possible scores. The higher the scores, the better the QoL. Physical Health Composite (PHC) and Mental Health Composite (MHC) are derived by combining scores of the subscales. | The test is administered before the treatment, then after eight weeks of treatment, and finally two months after the end of the treatmen |
| Client Satisfaction Questionnaire (CSQ-8) | a self-administered post-treatment questionnaire, comprised of eight items that evaluate the level of satisfaction regarding the care and quality of the service received and the level of fulfillment of the patient's expectations regarding the treatment administered. The total score of the questionnaire is 32 points, with higher values meaning higher satisfaction with the treatment received. | At the end of the treatment |
