Abstract: A varus dropped foot, one of the most common deformities of hemiplegic lower limb in stroke patients, significantly affected the ability of ambulation. Electric stimulation therapy was one of mostly used techniques for this problem. This paper focused on the application of low frequency electric stimulation in the treatment of the varus dropped foot in stroke patients, analyzed the clinical efficacy and advantage of neuromuscular electrical stimulation and functional electrical stimulation, and the discussion of their mechanism.
