Background - Walking patterns of stroke survivors are commonly characterized by spatiotemporal gait asymmetry, caused by impaired weight shift towards the paretic stance leg. Since weight shift is controlled by lateral pelvic movements in able bodied persons, interventions focusing on pelvic displacement during gait are required. Therefore, the aim of the current study was to determine the effect of mediolateral pelvic support provided by gait rehabilitation robot LOPES II on gait symmetry and muscle activation patterns of subacute stroke patients. Methods – Seven subacute stroke patients completed three trials of three minutes walking in LOPES II, with the mediolateral pelvic guidance force set at 5% during the first and last trial and set at 50% during the pelvic support condition. Lateral pelvic displacement, spatiotemporal gait symmetry and EMG activity of seven muscles of the paretic leg were recorded and compared between trials. Results – Lateral pelvic displacement increased when pelvic support was provided, resulting in more symmetrical pelvic displacements towards the paretic and non-paretic stance leg and a trend towards improvements in step width and swing time symmetry. Alterations in muscle activity were observed during stance, with larger activity of the hip abductor muscle when pelvic support was received. No retention effects of pelvic support on the lateral pelvic displacement and gait symmetry were observed. Conclusion – Mediolateral pelvic support enhanced pelvic displacement, resulting in a trend towards gait symmetry and increased hip abductor activity during paretic stance. Extended gait training is needed to determine the clinical implications of robotic pelvic support in restoring gait performance of stroke survivors.
