Study Overview
Brief Summary
Researchers are gathering information on the safety and effectiveness of a new device called the BalanceBelt.
Detailed Description
Ten consecutive subjects, ages 25-70 years, diagnosed with Chronic Subjective Dizziness (CDS) and ten healthy age and gender matched subjects will be asked to perform tests involving walking and balance while wearing the BalanceBelt. The BalanceBelt is a lightweight belt that will be worn under the clothes around the subjects waist and uses sensitive motion detectors and vibrates against the skin at four locations to provide information about posture and motion.

Eligibility Criteria
- Ages
- 25 Years to 70 Years (Adult, Older Adult)
- Sex
- All
- Accepts Healthy Volunteers
- Yes
Inclusion Criteria
- •Subjects will be 25-70 years of age inclusive and pregnant women may participate.
- •Patients will have CSD as their primary diagnosis for the cause of their balance and dizziness complaints provided by the Behavioral Medicine Program for Dizziness, a division of the Department of Psychiatry & Psychology.
- •Normal volunteers will have a negative history of otologic & neurologic disorders and no history of dizziness and balance problems.
- •Normal volunteers will have normal findings on a screening office examination for peripheral and central vestibular system involvement (see methods for details of the examination) and screening for normal or symmetrical hearing loss of explainable origin.
Exclusion Criteria
- •Patients with positive indications from testing of peripheral and/or central vestibular system involvement that is felt to be influencing the symptoms reported beyond the CSD alone.
- •Patients with mobility restriction that would prevent participating in the tests or the intensive therapy trials.
- •Subjects with hearing impairment that interferes with oral communication.
Arms & Interventions
Chronic Subjective Dizziness Syndrome Subjects
Subjects diagnosed with Chronic Subjective Dizziness Syndrome (CDS) will wear the BalanceBelt while performing test involving walking and balance.
Intervention: Balance Belt (Device)
Healthy Subjects
Age matched healthy subjects without complaints of balance or dizziness problems will wear the BalanceBelt while performing test involving walking and balance.
Intervention: Balance Belt (Device)
Outcomes
Primary Outcomes
Degrees of Sway
Time Frame: baseline
The Sensory Organization Test is a six condition standard evaluation of balance control performed on a dynamic platform that can record sway movement in the A/P dimension while the sensory inputs from proprioception and vision are varied though the platform and visual surround movements. Condition 1 - eyes open, visual locked, platform locked. Condition 2 - eyes closed, visual locked, platform locked. Condition 3 - eyes open, visual unlocked, platform locked. Condition 4 - eyes open, visual locked, platform unlocked. Condition 5 - eyes closed, visual locked, platform unlocked. Condition 6 - eyes open, visual unlocked, platform unlocked. All participants progress though the exam, starting with condition 1 and ending with condition 6. All conditions were completed two to three times depending on performance with the average of each condition reported.
