A Task-oriented Circuit Training in Multiple Sclerosis

Our primary hypothesis is that a two weeks high-intensity task-oriented circuit training followed by a structured 3 months home exercise program would have higher benefits compared to a delayed-treatment group as control in people with multiple sclerosis and mild to moderate gait impairment.

Our secondary hypothesis is that there could be retention of clinical gains in subjects that underwent TOCT plus structured 3 months home exercise program.

About this study

This is a single blind randomized-controlled trial to test the effects of a task oriented training on locomotor function, mobility and balance in multiple sclerosis subjects with mild to moderate gait impairments (EDSS 4-5.5).

Subjects and methods:54 multiple sclerosis patients will be recruited in two outpatient rehabilitation clinics (Azienda Ospedaliero- Universitaria di Ferrara and Azienda Ospedaliero-Universitaria Pisana). Informed consent will be obtained. Participants enrolled will be included in 2 different treatment groups: experimental group will receive 10 TOCT sessions over 2 weeks (2 hours/each session) followed by a 3 months home exercise program, whereas control group will be included into a delayed-treatment group. Three subjects with a supervisor physiotherapist will take part at the TOCT. Primary outcome measure will be walking endurance (Six Minute Walking Test); as secondary outcome we will test gait speed (Timed 25-Foot Walk), balance (Dynamic Gait Index) and mobility (Time Up and Go Test); through self-assessment questionnaires we will evaluate motor fatigue (Modified Fatigue Impact Scale - MFIS), walking ability (Multiple Sclerosis Walking Scale - 12), health-related quality of life (Multiple Sclerosis Impact Scale - 29 and Functional Assessment of Multiple Sclerosis). In addition to clinical outcomes, in a convenience sample we will have: (i) balance assessment (force platform); (ii) motorcortex oxygenation during walking (fNIRS); (iii) muscle oxygenation (NIRS); (iv) force and EMG signal; (v) mechanical and electrical fatigue assessment; (vi) brain connectivity (EEG). Outcome measures will be assessed 1 week prior to treatment initiation (T0), after two weeks to treatment initiation (T1), after the 3 months exercise program (T2) and at 3 months follow-up (T3) to evaluate treatments retention, by a clinician blinded to the treatment.

The specific aims will be (i) to test the effects on walking, mobility, balance, fatigue and health-related quality of life; (ii) to test the effects on cerebral oxygenation (fNIRS) during walking; (iii) muscle oxygenation (NIRS); (iv) force and EMG signal; (v) Mechanical and electrical fatigue assessment; (vi) brain connectivity (EEG) and (vii) to investigate the 3 months home exercise program's feasibility, satisfaction and adherence.

Treatment and study plan

Task Oriented Circuit Training

Behavioral

TOCT includes six different workstations in which subjects exercise for 5 minutes in each one (3 minutes of exercise and 2 minutes of rest). During each session, subjects undergo 2 laps that take about 60 minutes (6 workstation × 5 minutes × 2 laps), with 10 minutes of rest after each lap. In addition, walking endurance is trained by 30 minutes walking on the treadmill including rests if necessary. This is a progressive circuit and subjects while exercising receive feedbacks (visual and auditory) by the physiotherapist. Rests are used to discuss about difficulties and to provide further feedbacks. One session includes up to 3 patients and lasts 120 minutes, 5 days/week for 2 weeks. After this period they will receive a home-exercise maintenance program for 3 months.

Delayed Onset TOCT

Behavioral

The control group will not receive any specific rehabilitation treatment for gait performance and mobility improvement. At any case, the control group will be authorized, at will, to exercise in non-rehabilitative contexts (i.e. swimming, walking, yoga) for 14 weeks. After this period they will receive TOCT as treatment plus a home-exercise maintenance program for 3 months.

Primary outcomes

  1. Six-Minute Walking Test

    Time frame: Weeks: 0,2,14, 26

    The walking endurance is measured with the Six-Minute Walking Test. Subjects are instructed to walk up and down as far as possible a 22m walkway in six minutes, with the possibility to slow down and rest if necessary.

Secondary outcomes

  1. Timed 25-Foot walk (25FWT)

    Time frame: weeks: 0,2,14, 26

    a quantitative measure of lower extremity function, also included in the Multiple Sclerosis Functional Composite (MSFC) . The patient is directed to one end of a clearly marked 25-foot course and is instructed to walk 25 feet (7.62m) as quickly as possible, but safely, using the prescribed assistive devices. The task is immediately administered again by having the patient walk back the same distance. Test will be performed according to the instructions reported on the manual of the National Multiple Sclerosis Society .

  2. Time Up and Go Test

    Time frame: weeks: 0,2,14, 26

    Subjects will be given verbal instruction to stand up from a chair, walk 3 meters, cross a line marked on the floor, turn around, walk back, and sit down. A study staff member will guard the subject during the test. Subjects will perform 3 trials and the time it takes to perform each trial will be recorded with a stopwatch.

  3. Dynamic Gait Index (DGI)

    Time frame: weeks: 0,2,14, 26

    Assesses individual's ability to modify balance while walking in the presence of external demands

  4. Modified fatigue impact scale (MFIS)

    Time frame: weeks: 0,2,14, 26

    The MFIS is a modified form of the Fatigue Impact Scale (Fisk et al, 1994) based on items derived from interviews with MS patients concerning how fatigue impacts their lives. This instrument provides an assessment of the effects of fatigue in terms of physical, cognitive, and psychosocial functioning.

  5. Multiple Sclerosis Walking Scale - 12 (MSWS-12)

    Time frame: weeks: 0,2,14, 26

    The 12-item multiple sclerosis walking scale (MSWS-12) is a self-report measure of the impact of MS on the individual's walking ability.

  6. Multiple Sclerosis Impact Scale- 29 (MSIS-29)

    Time frame: weeks: 0,2,14, 26

    This is an health-rated quality of life questionnaire that assesses the impact of MS on physical and psychological functions. It is formed by 29 items on ADL I and II: 20 about physical activity and 9 of psychological status of the person. Each item can be scored with a value from 0 to 5; total score is given by the sum of all the items and then is transformed in a range from 0 to 100. A higher value correspond to a worse perception of subject's HRQoL.

  7. Functional Assessment of Multiple Sclerosis (FAMS)

    Time frame: weeks: 0,2,14, 26

    Quality of life instrument of for use in people with MS. Consists of 59 items (44 of which are scored) in six quality of life domains. Higher scores indicate better quality of life.

  8. Metabolic cerebral measurements by Near infrared spectroscopy

    Time frame: weeks: 0,2,14, 26

    Near InfraRed Spectroscopy (NIRS) is a noninvasive, portable technique for ambulatory or remote monitoring of human motor-cortex oxygenation changes in response to motor tasks. Patients will walk on the treadmill at a speed of 0.2 km/h assisted by personnel and with partial body weight support, performing 4 short tasks (30 seconds of walking) alternated by rest periods (30 seconds).
