ABSTRACT

Postural instability (PI) and falls are major sources of disability in Parkinson’s disease (PD). Our objectives were to evaluate the correlation between the pull-test (PT) scores and falls. Patients underwent a standardized data collection including demographic, clinical data, and the UPDRS scores for falls and the PT. Cases with scores >1 for falls were considered frequent fallers. 264 patients were included with mean age 67.6±10 years, mean age of onset 59.1±10.7 years. Comparison between PT scores versus the proportion of frequent fallers and the mean score of the UPDRS for falls showed that for each increase in the PT score, both parameters were significantly worse, with positive linear relationship. For any abnormal PT score, sensibility and negative predictive value were excellent; specificity and positive predictive value improved with worse PT scores. In conclusion, the PT provides important and reliable information regarding PI and the risk of falls in PD.


Instabilidade postural (IP) e quedas são importantes fontes de incapacidade na doença de Parkinson (DP). Nossos objetivos foram avaliar a correlação dos escores do test de retropulsão (TR) com história de quedas. Pacientes foram submetidos a coleta de dados padronizada, incluindo dados demograficos, clinicos e escores da UPDRS para quedas e do TR. Escores >1 para quedas definiram casos com quedas freqüentes. 264 pacientes foram incluídos, idade média de 67,6±10 anos, idade média de início 59,1±10,7 anos. Comparação do escore do TR com a proporção de casos com quedas freqüentes e pontuação média para quedas mostrou que, para cada aumento na pontuação do TR, ambos os parâmetros pioraram significativamente, com relação linear. Para escores anormais no TR, sensibilidade e valor preditivo negativo foram excelentes; especificidade e valor preditivo positivo melhoraram com escores maiores. Conclusão: o TR fornece informações importantes e confiáveis sobre IP e risco de quedas em PD.
