To evaluate the association between baseline characteristics, three physical performance tests and fall history in a sample of the elderly from Korean population.
A total of 307 participants (mean age, 76.70±4.85 years) were categorized into one of two groups, i.e., fallers and non-fallers. Fifty-two participants who had reported falling unexpectedly at least once in the previous 12 months were assigned to the fallers group. Physical performance tests included Short Physical Performance Battery (SPPB), Berg Balance Scale (BBS), Timed Up and Go test. The differences between the two study groups were compared and we analyzed the correlations between fall histories and physical performance tests.
SPPB demonstrated a significant association with fall history. Although the BBS total scores did not show statistical significance, two dynamic balance test items of BBS (B12 and B13) showed a significant association among fallers.
This study suggests that SPPB and two dynamic balance test items of the BBS can be used in screening for risk of falls in an ambulatory elderly population.

To demonstrate the efficacy of the balance control trainer (BCT), developed for training patients with balance problems, as a balance assessment tool in subacute stroke patients.
A prospective cross-sectional study was carried out on 38 subacute stroke patients in their first episode of a stroke, and having the ability to maintain a standing position without aid for at least 5 minutes. Patients were assessed using the BCT (BalPro) 43.7±35.7 days after stroke. The balance was assessed using the Berg Balance Scale (BBS), the Timed Up and Go Test (TUG), a 10-meter walking test (10mWT), a 6-minute walking test (6MWT), and the Korean version of the Modified Barthel Index. The correlation and validity between the BCT and various balance assessments were analyzed.
Statistically significant linear correlations were observed between the BCT score and the BBS (r=0.698, p<0.001). A moderate to excellent correlation was seen between the BCT score and 11 of the 14 BBS items. The BCT scores and other secondary outcome parameters (6MWT r=0.392, p=0.048; TUG r=–0.471, p=0.006; 10mWT r=–0.437, p=0.012) had a moderate correlation.
Balance control training using the BCT (BalPro) showed significant statistical correlation with the BBS, and could therefore be a useful additional balance assessment tool in subacute stroke patients.

Objective: To examine the correlation between Berg balance scale (BBS) which is tool for assessing the clinical balance function and sensory organization test (SOT) of computerized dynamic posturography (CDP) in brain injured patients.
Method: Thirty patients with brain injury were assessed on the BBS and SOT of CDP. BBS consists of 14 items and each item is graded on a five point ordinal scale (0∼4), yielding a total of 56 points. According to its characteristics, each item was divided 3 groups, which were sitting, standing and position change. Six equilibrium scores (EQ) were determined by SOT of CDP (EquiTest SystemⰒ, Version 5.08) under 6 conditions, and somatosensory, visual, vestibular ratios were analyzed by 6 EQ scores.
Results: EQ 5 was correlated with reaching forward item (r=0.513), turning 360 degrees item (r=0.537), stool stepping item (r=0.529) of BBS (p＜0.01). EQ 6 was correlated with turning 360 degrees item (r=0.498) of BBS (p＜0.01). Sum of standing item group scores was correlated with EQ 5 (r=0.478), EQ 6 (r=0.464), and sum of position change item scores was correlated with EQ 5 (r=0.622), EQ 6 (r=0.514)(p＜0.01). Vestibular ratio was correlated with BBS total score (r=0.552, p＜0.01).
Conclusion: We concluded that vestibular ratio of SOT was correlated with BBS, especially position change item group. Therefore BBS is a good tool for evaluating vestibular function in brain injured patients.
