Study Endpoints

Primary Endpoints

Change from baseline in the knee extension strength at 21 weeks
Baseline and 21 weeks

Knee extension strength will be evaluated by isokinetic dynamometry

Change From Baseline to 6 Months in Gait Speed for 400 Meter Walking (MW) Test
Baseline and 6 Months

Gait speed was measured using the 400 MW test, which measured how long it took the participant to walk a distance of 400 meters. Missing data imputed using adjusted Bayesian Multiple Imputation (MI) methods for Non-Completers who failed to perform the Test feasibility and Multiple Imputation for participants who without data on on-Site visit. Data up to 9 months was used where 6 months data were unavailable for participants enrolled during the COVID-19 pandemic.
