TI  - Validity, Reliability, and Ability to Identify Fall Status of the Berg Balance 
      Scale, BESTest, Mini-BESTest, and Brief-BESTest in Patients With COPD.
PG  - 1807-1815
AB  - BACKGROUND: The Berg Balance Scale (BBS), Balance Evaluation Systems Test 
      (BESTest), Mini-BESTest, and Brief-BESTest are useful in the assessment of 
      balance. Their psychometric properties, however, have not been tested in patients 
      with chronic obstructive pulmonary disease (COPD). OBJECTIVE: This study aimed to 
      compare the validity, reliability, and ability to identify fall status of the 
      BBS, BESTest, Mini-BESTest, and the Brief-BESTest in patients with COPD. DESIGN: 
      A cross-sectional study was conducted. METHODS: Forty-six patients (24 men, 22 
      women; mean age=75.9 years, SD=7.1) were included. Participants were asked to 
      report their falls during the previous 12 months and to fill in the 
      Activity-specific Balance Confidence (ABC) Scale. The BBS and the BESTest were 
      administered. Mini-BESTest and Brief-BESTest scores were computed based on the 
      participants' BESTest performance. Validity was assessed by correlating balance 
      tests with each other and with the ABC Scale. Interrater reliability (2 raters), 
      intrarater reliability (48-72 hours), and minimal detectable changes (MDCs) were 
      established. Receiver operating characteristics assessed the ability of each 
      balance test to differentiate between participants with and without a history of 
      falls. RESULTS: Balance test scores were significantly correlated with each other 
      (Spearman correlation rho=.73-.90) and with the ABC Scale (rho=.53-.75). Balance 
      tests presented high interrater reliability (intraclass correlation coefficient 
      [ICC]=.85-.97) and intrarater reliability (ICC=.52-.88) and acceptable MDCs 
      (MDC=3.3-6.3 points). Although all balance tests were able to identify fall 
      status (area under the curve=0.74-0.84), the BBS (sensitivity=73%, 
      specificity=77%) and the Brief-BESTest (sensitivity=81%, specificity=73%) had the 
      higher ability to identify fall status. LIMITATIONS: Findings are generalizable 
      mainly to older patients with moderate COPD. CONCLUSIONS: The 4 balance tests are 
      valid, reliable, and valuable in identifying fall status in patients with COPD. 
      The Brief-BESTest presented slightly higher interrater reliability and ability to 
      differentiate participants' fall status.
