Trial summary

The investigators hypothesis is that electrical stimulation to the tongue that directly stimulates two cranial nerve nuclei (Trigeminal and Facial Nerve Nuclei), will excite neural impulses to the brainstem and cerebellum.

Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 to 90 years
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • Subjects must be age 18 or older.
  • Subjects will have a score between 6.5 to 7.5 on the Kurtzke Expanded Disability Status Scale (EDSS). The EDSS is a method of quantifying disability in people with multiple sclerosis.
  • Score of 6.5: needs constant bilateral support to walk 20 meters without resting.
  • Score of 7.0: unable to walk beyond five meters even with aid, and is essentially restricted to a wheelchair; wheels self and transfers alone, and is active in wheelchair about 12 hours a day.
  • Score of 7.5: unable to take more than a few steps and is restricted to wheelchair, and may need aid to transfer; wheels self, but may require a motorized chair for a full day's activities.
  • Subjects will have reached a plateau in an MS focused physical rehabilitation program in the 6 months prior to enrollment.

  • Requiring prior physical therapy will ensure that subjects have a core level of function that will allow them to participate in the study.
  • Requiring that subjects have reached a plateau will ensure that subjects' response to the intervention is due to the use of the device and not to the physical exercises alone.
  • Subjects who have participated in a physical rehabilitation program demonstrate that they are willing and able to commit to a rigorous training regimen.
  • Subjects will have a maximum score of 20 on the Trunk Impairment Scale (TIS). The TIS assesses static dynamic sitting balance and trunk coordination in a sitting position. A score of 20 or lower indicates that their ability to adequately maintain sitting posture is affected.
  • Subjects may have upper extremity involvement.
  • Subjects may have additional symptoms of nystagmus, dysarthria, sensory disturbance, pain, and/or bowel and bladder function. As they present, we will use appropriate assessments at baseline and successive study test points.
  • Subjects are their own legal guardians, and are able to understand and give informed consent.

Who cannot join

  • Subjects will have no major co-morbidities, especially neurological disorders, uncontrolled pain, hypertension or diabetes. All subjects, if on medications, will not have had any major changes in type or dosage in within 3 months of enrollment. Additionally, candidates will be excluded if they:
  • have Functional Systems Scores (FSS) 4 or greater for pyramidal, cerebellar, brainstem, and sensory functions; 3 or greater for bowel and bladder function; and 2 or greater for cerebral function;
  • are able to walk independently;
  • use tobacco products (these activities tend to reduce tactile sensitivity in the oral cavity);
  • have any oral abrasions, cuts, cold sores, piercings, tissue inflammation, or have had oral surgery within the previous 3 months;
  • have a pacemaker, or are identified as at-risk for cardiovascular events;

About this study

The investigators hypothesis is that electrical stimulation to the tongue that directly stimulates two cranial nerve nuclei (Trigeminal and Facial Nerve Nuclei), will excite neural impulses to the brainstem and cerebellum. The investigators call this cranial nerve non-invasive neuromodulation (CN-NINM). The activation of these structures induces neuroplasticity when combined with specific physical exercises, can reduce symptoms of advanced MS, targeting primarily postural stability (sitting and standing), upper extremity movement, and ability to perform self-transfers.

Read the detailed description

The intervention will be similar to that used in the investigators previous work with movement disorders, and will be tailored to the address issues unique to individuals with advanced MS.

The study will enroll a total of 6 subjects having advanced MS that present with significant seated and standing balance, posture, or movement control deficits due to MS.

Subjects will complete twice-daily lab training for two weeks (5 days/week). Each lab training (morning and afternoon) includes 1.5 to 2 hours of instruction in balance, posture and gait activities; therapeutic exercise for isolated muscle control; transfer training; and relaxation training.

Activities are performed in 20-minute sessions with concomitant electrical stimulation of the tongue. The intervention is customized according to each subject's particular symptoms and tolerance. If a subject is not able to perform this amount of training, the training will be adapted to a level that is tolerable.

After these 2 weeks, subjects will continue to perform these same intervention activities at home for 4 weeks. They will return to the lab for 1 week of training and testing, then perform home training for 4 weeks. This cycle is repeated for a total of 5 cycles.

After the 6 months have been completed, subjects may choose to participate in an optional second phase of the study. The second phase includes an additional 12 months of participation in which subjects perform the intervention activities at home training and return to the lab on time per month for 2 hours of testing and 2 hours of training.

If successful, this study would indicate that CN-NINM intervention may reduce the symptoms of advanced MS.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Neuromodulation RehabilitationDevice

    Also called Cranial Nerve Non-invasive Neuromodulation (CN-NINM), Portable Neuromodulation Stimulator (PoNS)

    CN-NINM uses sequenced patterns of electrical stimulation on the tongue. Our hypothesis is that CN-NINM induces neuroplasticity by noninvasive stimulation of two major cranial nerves: trigeminal, CN-V, and facial, CN-VII.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Trunk Impairment Scale (TIS)

    Static and dynamic sitting balance and trunk coordination are evaluated by a clinician. It is scored on a scale from 0-23, where the higher the score, the more improved the balance. Effect size is reported (quantified difference between baseline and time point). The larger the absolute value, the stronger the effect. Cohen's guidelines for social sciences indicate 0.10 as a "small" effect size, 0.30 as a "medium" effect size, and 0.50 as a "large" effect size.

    Measured: Change from Baseline at 2, 6, 11, 16, and 21 weeks

Secondary outcomes (17)

    The GMFM a standardized observational instrument that measures change in gross motor function. Subscales include lying \& rolling; sitting; crawling \& kneeling; standing; and walking, running \& jumping. For the complete test, the raw scores are converted to a 0-100 scale, with higher scores indicating greater functional mobility. The items that we used were scored on a 0-3 scale and changes reported in percent improvement. Performance-based and tested in participants who possessed the ability to perform the assessment. Effect size is reported (quantified difference between baseline and time point). The larger the absolute value, the stronger the effect.

  16. Slump Test

    Measures and quantifies changes in trunk control during functional sitting. It was quickly determined that this test duplicated the TIS and was difficult to score objectively so the decision was made not to use it for the study. Performance-based and tested in participants who possessed the ability to perform the assessment.

    Measured: Change from Baseline at 2, 6, 11, 16, 21 and 27 weeks

  17. Modified Rivermead Mobility Index

A higher score indicates higher function. Performance-based and tested in participants who possessed the ability to perform the assessment. Effect size is reported (quantified difference between baseline and time point). The larger the absolute value, the stronger the effect. Cohen's guidelines for social sciences indicate 0.10 as a "small" effect size, 0.30 as a "medium" effect size, and 0.50 as a "large" effect size.

    Measured: Change from Baseline at 2, 6, 11, 16, 21 and 27 weeks

What does the primary outcome measure?

Trunk Impairment Scale (TIS) (time frame: Change from Baseline at 2, 6, 11, 16, and 21 weeks). It is what the study was designed to measure, not a finding.
