BACKGROUND While excessive ankle plantarflexion is a common neuromuscular impairment resulting from insufficient coordination of selective ankle neuromotor control and kinematics during gait. We recently developed a wearable, inexpensive and sustainable wearable ankle-tubing gait training (WAGT) aimed at improving selective ankle motor control and kinematic coordination. OBJECTIVE We investigated the effects of WAGT on tibialis anterior (TA) and gastrocnemius (GCM) muscle electromyography (EMG) activity, TA: GCM muscle imbalance ratio, and ankle joint kinematics during gait in hemiparetic stroke patients. METHODS A convenience sample of 33 participants (15 non-stroke healthy adults and 18 hemiparetic stroke patients) underwent standardized electromyography and kinematic biomechanical tests under conventional gait training (CGT) and WAGT conditions. Analysis of variance (ANOVA) was used to determine the significance of differences in the TA: GCM muscle activation, muscle imbalance ratio, and ankle joint kinematics before and after the intervention and between the two groups at P <  0.05. RESULTS WAGT was more effective than CGT in improving TA muscle activation (P <  0.01), TA: GCM muscle imbalance ratio (P <  0.01), and kinematic movement (P <  0.01) in adults with or without hemiparetic stroke. CONCLUSIONS This study demonstrated that WAGT is relatively ease to design, wear and affordable to most clinicians and patients, hence it is suitable for many health care applications to correct gait-related movement abnormalities presented in the hemiparetic stroke patients.
