Overview
Brief Summary
The purpose of this study is to determine the feasibility of combining PoNS therapy with standard vestibular and balance therapy with the proposed double-blind design; evaluate preliminary indications of efficacy. This study is also evaluating recruitment rate, completion rate, device usability, and outcome measures feasibility.
- Goal for recruitment: 100% of 30 subjects meeting all inclusion criteria can be recruited over the 36 week pilot recruitment phase.
- Completion and compliance: 90% of subjects will complete the study, 90% of sessions within each subject will be completed, and for completing subjects, 100% of measures will be completed.
- Useability: all therapists and subjects must rate useability as good or better.
- Success of blind: subject accuracy at guessing group membership must be at or near 50%.
