INTRODUCTION: The clinical course of late-onset Pompe disease is heterogeneous, and new clinical outcome measures are needed to evaluate enzyme replacement therapy (ERT).METHODS: We correlated the 6-Minute Walk Test (6MWT), Walton and Gardner-Medwin (WGM) score, and GSGC (Gait, Stairs, Gower, Chair) scores in 40 patients.RESULTS: At baseline, the GSGC score correlated with both WGM (P < 0.001, n = 33) and 6MWT (P < 0.001, n = 26). After 1 year of ERT, we observed a significant change in gait, stairs and chair performance on the GSGC scale. The 6MWT significantly increased from 319 to 371 meters in 32 patients, and the WGM score was reduced.CONCLUSIONS: GSGC is a group of functional tests that requires only a few minutes to perform, therefore, this score might be a good indicator to be used in future studies.

Abstract

INTRODUCTION: The clinical course of late-onset Pompe disease is heterogeneous, and new clinical outcome measures are needed to evaluate enzyme replacement therapy (ERT).METHODS: We correlated the 6-Minute Walk Test (6MWT), Walton and Gardner-Medwin (WGM) score, and GSGC (Gait, Stairs, Gower, Chair) scores in 40 patients.RESULTS: At baseline, the GSGC score correlated with both WGM (P < 0.001, n = 33) and 6MWT (P < 0.001, n = 26). After 1 year of ERT, we observed a significant change in gait, stairs and chair performance on the GSGC scale. The 6MWT significantly increased from 319 to 371 meters in 32 patients, and the WGM score was reduced.CONCLUSIONS: GSGC is a group of functional tests that requires only a few minutes to perform, therefore, this score might be a good indicator to be used in future studies.
