Fig. 3From: These legs were made for propulsion: advancing the diagnosis and treatment of post-stroke propulsion deficitsa Combining isometric strength testing with supramaximal muscle electrostimulation allows assessment of the extent and nature of post-stroke muscle weakness (i.e., maximum voluntary strength, strength capacity, and the ratio of these force measurements is the Central Drive). b Central drive is a key explanatory factor of paretic propulsion and propulsion asymmetry across individuals with a wide range of walking speeds.
