BACKGROUND: Individuals with stroke have impaired sensorimotor function of ankle. OBJECTIVE: To investigate the effects of passive biaxial ankle movement training synchronized with electrical stimulation therapy (AMT-EST) on ankle proprioception, passive range of motion (pROM), and strength, balance, and gait of chronic stroke patients. METHODS: Thirty-five stroke patients were randomized. The experimental group received a total of 20 AMT-EST sessions. The control group received only EST. Primary outcome measures were ankle functions. Secondary outcome measures were clinical assessments of motor, balance, and gait-related functions. All assessments were compared before and after the intervention. RESULTS: The experimental group had significantly improved ankle dorsiflexor strength (p = 0.015) and ankle pROM during foot supination (p = 0.026) and pronation (p = 0.004) and clinical assessment (Fugl–Meyer Assessment of the lower extremities [FM-L], Berg Balance Scale, Timed Up and Go test, Fall Efficacy Scale, walking speed, and step length; all p < 0.05) values. The regression model predicting ankle proprioception showed significantly large effects (adjusted R2 = 0.493; p < 0.01) of the combined FM-L score and time since stroke. CONCLUSION: Biaxial AMT-EST resulted in better ankle pROM and strength than conventional EST. Ankle proprioception was not significantly improved after AMT-EST and was predicted by the FM-L score and time since stroke.
