What this trial studies

This observational study evaluates the psychometric properties of the French version of the Primary Lateral Sclerosis Functioning Rating Scale (PLSFRS) across eight ALS centers in France. It aims to enroll 80 patients diagnosed with primary lateral sclerosis (PLS) who will be assessed at three different time points using both the ALSFRS-r and PLSFRS scales. The study seeks to ensure that the PLSFRS is culturally and linguistically appropriate for the French population, thereby enhancing its utility in clinical settings.

Who should consider this trial

Good fit: Ideal candidates for this study are adults over 18 years old diagnosed with primary lateral sclerosis who can provide informed consent.

Not a fit: Patients who do not speak French or are unable to complete questionnaires will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a validated tool for better assessing the functional status of patients with primary lateral sclerosis in French-speaking populations.

How similar studies have performed: While this study focuses on validating a specific scale, similar studies have successfully validated other assessment tools for ALS, indicating a promising approach.
