Ankle torque fluctuations and intramuscular coherence were evaluated during a dorsiflexion task at 30% of maximum voluntary torque (MVT). Walking performance was assessed using the 5-meter walk test and the Timed Up and Go (TUG) test. Torque fluctuation indicators, including the coefficient of variation (CV), frequency components, and the primary component calculated by an autoregressive (AR) model, were derived from time-series data.
