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 ) .
External validation of a simple clinical tool used to predict falls in people with Parkinson disease.
BACKGROUND Assessment of fall risk in an individual with Parkinson disease ( PD ) is a critical yet often time consuming component of patient care . Recently a simple clinical prediction tool based only on fall history in the previous year , freezing of gait in the past month , and gait velocity < 1.1 m/s was developed and accurately predicted future falls in a sample of individuals with PD . METHODS We sought to externally vali date the utility of the tool by administering it to a different cohort of 171 individuals with PD .  Falls were monitored prospect ively for 6 months following predictor assessment . RESULTS The tool accurately discriminated future fallers from non-fallers ( area under the curve [ AUC ] = 0.83 ; 95 % CI 0.76 - 0.89 ) , comparable to the developmental study . CONCLUSION The results vali date d the utility of the tool for allowing clinicians to quickly and accurately identify an individual 's risk of an impending fall
