NCT03684369

Brief Summary

The objective of the clinical trial is to quantify the capacity of a translatable protocol of electrical nerve stimulation (TENS) to improve walking performance and self-reported disabilities of persons with MS. The hypothesis is that activation of sensory nerve fibers with augmented TENS promotes recovery of sensorimotor function and improves the disability status of individuals with MS. The rationale for the proposed clinical trial is that the approach provides a low-cost therapeutic strategy for persons with MS to manage walking limitations and fatigue.

Outcome Measures

Primary Outcomes (6)

  • Change in Gait Speed

    Time to walk 25 ft as quickly as possible

    Change from baseline at weeks 4, 8, and 12.

  • Change in Walking Endurance

    Distance walked in 6 min when walking at a brisk pace

    Change from baseline at weeks 4, 8, and 12

  • Change in Dynamic Balance

    Score achieved on the four components of the 14-item Mini-Balance Evaluation Systems Test (Mini-BESTest). The maximum score for each subscale are: anticipatory = 6, reactive postural control = 6, sensory orientation = 6, dynamic gait = 10. The subscales are added to provide a total score with a maximum of 28.

    Change from baseline at weeks 4, 8, and 12

  • Change in Patient Determined Disease Steps

    A questionnaire with a self-assessment scale of disease status. The scores range from 0 = normal to 8 = bedridden.

    Change from baseline at weeks 4, 8, and 12

  • Change in Modified Fatigue Impact Scale

    A questionnaire that assesses the impact of fatigue experienced by persons with MS. Each of the 21 items is rated from 0 = Never to 5 = Almost always. The maximum total score = 105

    Change from baseline at weeks 4, 8, and 12.

  • Change in MS Walking Scale-12

    A 12-item, patient-rated measure of how much MS compromises walking ability. Each item is rated from 1 = Not at all to 5 = extremely. The maximum total score = 60.

    Change from baseline at weeks 4, 8, and 12.

Secondary Outcomes (7)

  • Change in Romberg Quotient

    Change from baseline at weeks 4, 8, and 12.

  • Change Conditioned H-reflex Amplitude

    Change from baseline at weeks 4, 8, and 12.

  • Change in Proprioception Tract

    Change from baseline at weeks 4, 8, and 12.

  • Change in Muscle Synergy Number

    Change from baseline at weeks 4, 8, and 12

  • Change in Force Steadiness

    Change from baseline at weeks 4, 8, and 12.

  • +2 more secondary outcomes
