Brief summary

This is a national, multicentric, prospective, descriptive study evaluating the psychometric properties of the French version PLSFRS scale

Detailed description

This is a prospective study conducted in 8 French ALS centers which will enroll 80 patients with PLS. All these patients will undergo an evaluation of their functional status from the ALSFRS-r and PLSFRS scales. All patients will be evaluated at 3 time points (T0,M6 at the outpatient clinic) and at M3 remotely. The aim of the study will be to validate a trans-cultural and psychometric version of the PLSFRS available for the French PLS population.

Interventions
