Abstract
Hereditary spastic paraplegias (HSP) are characterized by progressive deterioration of axonal projections of upper motor neurons leading to abnormal locomotion. The clinical course of HSP as well as the definition of the best instruments to assess its progression is largely unknown. The aim of this study was to investigate the progression of functional gait in individuals with HSP and to define sensitivity to change, minimal clinically important difference (MCID), and validity of timed functional tests of gait (TFT). The study was constituted of two phases: a cross-sectional study and a prospective cohort of 18 months. Twenty-five patients (17 being SPG4), and twenty-five age- and sex-matched control individuals performed TFT. Spastic paraplegia rating scale (SPRS), ten-meter walking test (10MWT), timed up and go test (TUG), both at self-selected and maximal walking speeds, and six-minute walking test (6MWT) were performed on baseline in both groups and after 18 months of follow-up only in the HSP cohort. In the cross-sectional analysis, all TFTs performances were greatly impaired in HSP patients compared to controls. After 18 months of follow-up, TFTs did not differ significantly from baseline in the statistical analysis, with some tests showing more frequent improvement than worsening. We have provided effect size measures and MCID for the evaluated instruments. HSPs clearly compromised TFTs performances, which were valid instruments for assessing disease severity. However, TFTs and SPRS did not capture the very slow motor evolution of HSPs, reinforcing the necessity of additional biomarkers of disease progression.
