Zusammenfassung
Background: Assessment of motor phenotype and diagnosis of Huntington's Disease (HD) are based on the Unified Huntington's Disease Rating Scale-Total Motor Score (UHDRS-TMS), a categorical clinical scale. Therefore, results of clinical trials are limited by (1) subjective error, (2) sensitivity of the categorical scale, and (3) insensitivity in pre-manifest subjects. More objective and quantitative measures of motor phenotype are warranted. In a pilot study, we found increased variability of tongue force (TF) in pre-manifest and symptomatic HD, and correlation with genotype and UHDRS-TMS (Reilmann et al. 2005).…
