To prospectively evaluate the tools, environment and resources to compare the effectiveness of two different standard of care vestibular rehabilitation approaches in a military cohort with post-concussive vestibular symptoms.
Aim 1. To prospectively evaluate the reliability of a series of diagnostic and outcome assessment tools in a military cohort with post-concussive vestibular symptoms; these to include the Dizziness Handicap Inventory (DHI), Activities-Specific Balance Confidence Scale (ABC), the Computerized Dynamic Posturography (CDP) and the Neuro-Otologic Test System (NOTC).
Hypothesis 1. Active military personnel consist of physically high functioning individuals in whom standard diagnostic and outcome assessment tools may fail to target variations in performance. The investigators believe that active military personnel score different than general populations in standard diagnostic and outcome assessment tools.
Endpoint 1. The investigators will compare the DHI, ABC, CDP and NOTC results obtained in this study with historical data from the studies supporting the validation of each of the individual assessment tools.
Aim 2. To assess the concept of 'clinically meaningful change' as it relates to dizziness specific to a military cohort with post-concussive vestibular symptoms.
Hypothesis 2. Because of the differences in physical characteristics and performance demands between active duty military personnel and the general population, it is difficult to define if changes in diagnostic and outcome assessment evaluations in the military population reflect worsening or progression of symptoms at the same rate and magnitude observed in the general population.
Endpoint 2. The investigators will establish a comparison among study test results (DHI, ABC, CDP and NOTC) and compare these to clinical measures of response to treatment (Neurobehavioral Symptom Inventory - vestibular domain and Patients' Global Impression of Change Scale) to identify the rate and magnitude of change in the military cohort.
Aim 3. To compare scoring differences between subjects receiving individualized vestibular rehabilitation treatment (IVRT) and subjects receiving generalized vestibular rehabilitation treatment (GVRT), and to calculate the magnitude of change or the lack of it to determine the sample size for a subsequent comparative effectiveness trial.
Hypothesis 3. The combination of tests used in this study has not been used before; therefore, no data is available to calculate the sample size needed to determine comparative effectiveness between GVRT vs IVRT using DHI, ABC, CDP and NOTC.
Endpoint 3. The investigators will compare DHI, ABC, CDP and NOTC measurement results between treatment groups to estimate normal variation.
Aim 4. To refine methods, procedures, and information parameters for a comparative effectiveness trial assessing individualized vs. generalized vestibular rehabilitation therapy.
Endpoint 4. The investigators will evaluate and compare different elements inherent to the trial such as mechanisms of subject identification, evaluation times and tolerance, information tracking, etc. along with data obtained through the Patient Satisfaction Survey (PSS).

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Randomized GVRT | Other | Randomized Generalized Vestibular Rehabilitation Treatment (8 treatments) as part of standard of care (not research visits) |

|---|---|---|---|---|
| Generalized Vestibular Rehabilitation Treatment | Other | These treatment visits are available twice a week and each visit lasts 45 minutes. Individuals receiving GVRT are allowed to choose the frequency at which they want to attend and the program is designed for each subject to complete 8 visits within a period between 4 and 8 weeks. The ideal number of patients receiving treatment at each class is from 3 to 6 but the system has capacity for a maximum of 8. GVRT is a standard of care treatment option and is not considered research. |
| Measure | Description | Time Frame |
|---|---|---|
| Change in Dizziness Handicap Inventory (DHI) score | Self reported perception of handicap related to dizziness. 25 questions. Each item is scored 0 - 4 (0 = no, 2 = sometimes, 4 = always), yielding a total score between 0 (no perceived disability) and 100 (maximum perceived disability). Subscales related to certain questions are describes as physical, emotional and functional disabilities. | Baseline and 2 weeks after final treatment visit |
| Measure | Description | Time Frame |
|---|---|---|
| Change in Activities-specific Balance Confidence (ABC) Scale | Self reported level of confidence of not losing balance or becoming unsteady during specific activities. Participants rate their perceived confidence on a 0-100% scale (0% = no confidence, 100% = completely confident). Total score is averaged percentage of 16 questions. | Baseline and 2 weeks after final treatment visit |

| Individualized Vestibular Rehabilitation Treatment | Other | Individuals receiving IVRT are scheduled depending on their individual needs and PT availability. These visits require one-on-one time with a PT. Individuals are commonly seen by the PT 3 times at two week intervals. These visits last 30 minutes and include PT evaluation designed to instruct patients on exercises for them to perform on their own. IVRT is a standard of care treatment option and is not considered research. |

| Change in Equilibrium Score on Sensory Organization Test (SOT) | Equilibrium score quantifies postural stability during each of 3 trials of 6 sensory conditions obtained via Computerized Dynamic Posturography (CDP). Equilibrium is scored between 0 and 100 (0 = worst, 100 best). | Baseline and 2 weeks after final treatment visit |
| Change in Composite Equilibrium Score on Sensory Organization Test (SOT) | Composite Equilibrium Score is averaged from the six SOT Equilibrium Scores. Equilibrium score quantifies postural stability during each of 3 trials of 6 sensory conditions obtained via Computerized Dynamic Posturography (CDP).
