ObjectiveTo compare equilibrium scores between computerized dynamic posturography tests of the Sensory Organization Test (SOT) to the Head Shake-Sensory Organization Test (HS-SOT) in healthy adults.BackgroundApproximately 50% of the brain's pathways are related to vision and many of these pathways are susceptible to injury in concussion. Visual-motor disruptions occur in 65%–90% of concussed patients. These disruptions impair balance and can be measured. The SOT is a computerized postural test that evaluates balance by altering visual, proprioceptive, and vestibular cues. The HS-SOT modifies 2 of the standard SOT conditions by including dynamic head motions that stimulate the semicircular canals within the vestibular system.Design/MethodsParticipants completed the Dizziness Handicap Inventory, Activities of Balance Confidence Scale, SOT, and HS-SOT in one session.ResultsTwenty-five individuals (17 females, 8 males; mean age, 21.08 ± 4.10 years, range, 18–33 years) completed outcome measures and 3 trials of testing. There was a significant difference in mean values between the SOT and the HS-SOT for both condition 2 (t(16) = 3.034, p = 0.008) and 5 (t(16) = 5.706, p < 0.001). Additionally, there was a significant difference in mean values between the SOT and the foam HS-SOT for condition 2 (t(16) = 4.673, p < 0.001) and condition 5 (t(16) = 7.263, p < 0.001). There was not a significant difference in means between the foam and without foam for HS-SOT for condition 2 (t(16) = 1.77, p = 0.095) and condition 5 (t(16) = 1.825, p = 0.087).ConclusionsThe HS-SOT may quantify subtle balance deficits and enhance the clinical standard use of the SOT. Unlike the SOT where the head is static, the HS-SOT requires head movements, as if saying no repeatedly at approximately 100°/second as measured by an accelerometer. The HS-SOT may quantify subtle balance deficits and enhance the clinical standard use of the SOT.

<p class="abstract"><strong>Background:</strong> Postural control continues to change in later stages of life. Age-related changes may occur within or between sub-systems involved in postural control. It is thought clinically that these changes are important as they often result in falls &amp; injury. The aim of the work was to compare the balance characteristics among different age groups using computerized dynamic posturography to provide clinicians with normal references<span lang="EN-IN">. </span></p><p class="abstract"><strong>Methods:</strong> Inclusion criteria were study group consisted of (30) normal healthy individuals, age range 16-79 years, with neither hearing nor vestibular complaints. It was divided into 3 age groups, each group consisted of 10 patients. Group (A) young- 16-39 years, group (B) middle- 40-59 years and group (C) elderly- 60-79 years. Exclusion criteria were history of neuromuscular or neuroskeletal disease, symptoms of unsteadiness, dizziness or vertigo, symptoms of impaired sensory function, symptoms of arthritis or lower limb problem, symptoms of uncorrected visual problems, symptoms of postural hypotension or diabetes, medication intake such as sedatives, hypnotics, anxiolytics &amp; antidepressants.  All participants were subjected to full history taking, otologic examination, basic audiologic evaluation, computerized dynamic posturography which included sensory organization test, limits of stability and rhythmic weight shift<span lang="EN-IN">.  </span></p><p class="abstract"><strong>Results:</strong> <span lang="EN-IN">Sensory organization test: The elderly group (C) had lowest equilibrium score with eyes open, closed &amp; with conflicted visual cues on swayed surface (condition 6) and also this group have lowest percentage of SOT strategy. There was a statistically significant difference among A &amp; C groups when using sensory organization test strategy in all conditions. Limits of stability test: The elderly group has higher overall reaction time. There was statistically significant difference in all conditions of limits of stability as regards directional control. Rhythmic weight shift right and left test: There was a statistically significant difference between groups A &amp; C in low &amp; medium speed on on-axis velocity &amp; directional control. Rhythmic weight shift front &amp; back test: There was no statistically significant difference between all groups as regards on-axis velocity. There was highly statistically significant difference between all groups in all trials as regards directional control.</span></p><p class="abstract"><strong>Conclusions:</strong> Postural instability occurs frequently in healthy elderly subjects. Sensory organization test is the most effective test to compare balance function among different age groups<span lang="EN-IN">.</span></p>

OBJECTIVE: We sought to correlate the severity of vertigo and handicap in patients with vestibular pathology according to measures of impairment. STUDY DESIGN AND SETTING: We conducted a prospective assessment of patients with dizziness by means of caloric, rotatory test, and computerized dynamic posturography to estimate impairment. Handicap and severity of vertigo were determined with specific questionnaires (Dizziness Handicap Inventory and UCLA-DQ). RESULTS: A fair relationship were found between severity of dizziness and vestibular handicap. When impairment was taken into consideration, values were still fair and only moderate for a group of patients with an abnormal caloric test as the only pathologic finding. The composite score from the sensory organization test portion of the computerized dynamic posturography is fairly correlated to severity of vertigo and handicap in the whole population of patients, but no correlation was found when they were assigned to groups of vestibular impairment. CONCLUSION: To assess vestibular impairment, the results from several tests must be taken into account. However, vestibular handicap is not solely explained with measurements of impairment and/or severity.

Background Deficiencies in ankle proprioception and standing balance in basketball players with multiple ankle sprains have been reported in separate studies. However, the question of how ankle proprioceptive inputs and postural control in stance are related is still unclear. Hypothesis Ankle repositioning errors and the amount of postural sway in stance are increased in basketball players with multiple ankle sprains. Study Design Controlled laboratory study. Methods Twenty healthy male basketball players and 19 male basketball players who had suffered bilateral ankle sprains within the past 2 years were examined. Both groups were similar in age. Passive ankle joint repositioning errors at 5° of plantar flexion were used to test for ankle joint proprioception. The Sensory Organization Test was applied with dynamic posturography to assess postural sway angle under 6 sensory conditions. Results A significant increase in ankle repositioning errors was demonstrated in basketball players with bilateral ankle sprains (P < .05). The mean errors in the right and left ankles were increased from 1.0° (standard deviation, 0.4°) and 0.8° (standard deviation, 0.2°), respectively, in the healthy players to 1.4° (standard deviation, 0.7°) and 1.1° (standard deviation, 0.5°) in the injured group. A significant increase in the amount of postural sway in the injured subjects was also found in conditions 1, 2, and 5 of the Sensory Organization Test (P < .05). Furthermore, there were positive associations between averaged errors in repositioning both ankles and postural sway angles in conditions 1, 2, and 3 of the Sensory Organization Test (r = 0.39-0.54, P < .05). Conclusions Ankle repositioning errors and postural sway in stance increased in basketball players with multiple ankle sprains. A positive relationship was found between these 2 variables. Clinical Relevance Such findings highlight the need for the rehabilitation of patients with multiple ankle sprains to include proprioceptive and balance training.

Background: People with multiple sclerosis (MS) frequently have impaired postural control (balance). Psychometric properties of clinical tests of balance for individuals with MS, including the computerized dynamic posturography sensory organization test (CDP-SOT), are poorly understood. This study aimed to determine the reliability and discriminant validity of the CDP-SOT in people with MS. Methods: The CDP-SOT was performed on 30 participants with MS. A 2-week–interval, repeated-measures (sessions 1 and 2) design was implemented to investigate test-retest reliability of the CDP-SOT and the ability of the CDP-SOT to discriminate between participants with lower versus higher disability. Self-reported disability level was based on Patient-Determined Disease Steps (PDDS) scale scores: lower (PDDS scale score, 0–3; n = 17) and higher (PDDS scale score, 4–6; n = 13). Results: All six conditions of the CDP-SOT had good-to-excellent reliability (interclass correlation coefficients, 0.70–0.90) and excellent reliability for composite scores (0.90). Composite scores were significantly greater in the lower-disability group versus the higher-disability group at session 1 (70.89 vs. 48.60, P = .001) and session 2 (74.82 vs. 48.85, P = .002). Conclusions: The CDP-SOT is a reliable measure of balance and accurately differentiates disability status in people with MS. Collectively, the results support clinical application of the CDP-SOT as a reliable and valid measure of disease-related progression of impaired balance related to sensory integration and its utility in determining changes in balance in response to treatment.
