  Purpose

The purpose of this study is twofold:

  1. Establish baseline measures of gait performance in healthy young and older adults, and older adults with a history of falls.
  2. Investigate the effects of gait and balance training with and without cranial nerve noninvasive neuromodulation (CN-NINM) on postural balance and gait performance in older adults.

For the second purpose, the study will incorporate a placebo-controlled design to evaluate the effects of CN-NINM augmented exercise compared to physical exercises alone. Both groups will perform gait and postural balance training (outlined in more detail below) but will differ in the stimulation level of the PoNS device. The investigators will use the results of this study as a first step toward evaluating the benefits of CN-NINM in a falls prevention program.

Primary Outcome Measures:
  • Dynamic Gait Index [ Time Frame: Day 1 and approximately Day 12 ]
    An 8-item inventory of functional gait tasks each scored on a 0-3 point scale. Maximum score is 24 and any score of 19 or lower indicates an increased risk of falling.


Enrollment: 39
Study Start Date: September 2013
Study Completion Date: December 2015
Primary Completion Date: December 2015 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Young Adults - Intervention
Healthy subjects between the ages of 18-39 will participate in Cranial Nerve Non-Invasive Neuromodulation gait and balance training.
Device: Cranial Nerve Non-Invasive Neuromodulation
Portable device delivers electrical stimulation to cranial nerves V and VII via an electrode array placed on the anterior surface of the tongue. Stimulation is combined with rehabilitation exercises targeting walking and balance.
Other Name: PoNS (Portable Neuromodulation Stimulator)
Active Comparator: Healthy Older Adults - Control
Healthy subjects between age 65+ will participate in Sham Cranial Nerve Non-Invasive Neuromodulation gait and balance training.
Behavioral: Sham Cranial Nerve Non-Invasive Neuromodulation
Subjects participate in gait and balance rehabilitation exercises while using a device set to sub-threshold levels.
Active Comparator: Healthy Older Adults - Intervention
Healthy subjects age 65+ will participate in Cranial Nerve Non-Invasive Neuromodulation enhanced gait and balance training.
Device: Cranial Nerve Non-Invasive Neuromodulation
Portable device delivers electrical stimulation to cranial nerves V and VII via an electrode array placed on the anterior surface of the tongue. Stimulation is combined with rehabilitation exercises targeting walking and balance.
Other Name: PoNS (Portable Neuromodulation Stimulator)
Sham Comparator: Older Fallers - Control
Subjects who are age 65+ with a history of 1-3 falls in the previous six months will participate in Sham Cranial Nerve Non-Invasive Neuromodulation gait and balance training.
Behavioral: Sham Cranial Nerve Non-Invasive Neuromodulation
Subjects participate in gait and balance rehabilitation exercises while using a device set to sub-threshold levels.
