These measures assess balance and falls risk prediction at the body , structure and function level , falls risk and balance , and falls risk at the activity level .
The motor examination of the Unified Parkinson ’s Disease Rating Scale ( UPDRS-ME ) with robust psychometric analysis is a condition-specific measure with acceptable properties .
Conclusion : Six of the 68 outcome measures have strong psychometric properties for the assessment of balance and falls risk prediction in PD .
Objective : To investigate the psychometric properties of measures of balance and falls risk prediction in people with Parkinson ’s disease ( PD ) .
Diagnosis of Fall Risk in Parkinson Disease: An Analysis of Individual and Collective Clinical Balance Test Interpretation
Background and Purpose : Parkinson disease ( PD ) results in an increased frequency of falls relative to the frequency in neurologically healthy people . The purpose of this study was to compare the accuracy of PD fall risk diagnosis based on one test with that based on the collective interpretation of multiple tests . Participants : Seventy people with PD ( mean age=73.91 years ) participated in this study . Method : Clinical balance tests were conducted during the initial examinations of people with PD .  Validity indices were calculated for individual tests and compared with validity indices calculated for a combination of multiple tests . Results : Thirty-six participants reported a fall history . Analysis of individual tests revealed broad variations in validity indices , whereas the collective interpretation of multiple tests improved sensitivity and negative likelihood ratios . Discussion and Conclusion : Collective interpretation of clinical balance tests result ed in fewer false-negative results and more substantial adjustments to the posttest probability of being a “ faller ” than the interpretation of one test alone . These results should be confirmed in a prospect i ve examination of fall risk in PD
