Thumb-to-finger dysfunction is a difficult point in the treatment of stroke sequelae, affecting upper limb function and grasping ability. In this study, thumb-to-finger dysfunction was mainly due to decreased activation of the extensor and flexor muscles of the fingersThe results showed that the 2 therapies improved the pinching function between the thumb and 2 fingers, the flexion exercise of the interphalangeal joint extension exercise of the thumb, the neurological function defect after stroke, the grading of hand motor function, the degree of upper limb spasm, the muscle strength of the hand, muscle tone, the coordination function between each other and the muscle strength classification of patients after stroke, and the efficacy of the low-frequency group was significantly better than that of the EA group (This study explores the clinical effect of LFES therapy in the treatment of this disease, but there are some shortcomings and prospects. The main problems are: failure to compare and follow up the efficacy of cycles, and the inability to determine the optimal treatment cycle and long-term efficacy; The mechanism was not explored, only clinical efficacy was proved, and the mechanism of action and evaluation of safety and scope of adaptation could not be explained; Trials were conducted only in a single center, with small sample sizes, possible selection bias and regional variation, affecting our confidence in the results. It is recommended to improve the following in the future: regular follow-up of patients to clarify long-term clinical efficacy; Increase the comparison of clinical efficacy of cycles and clarify the optimal treatment cycle; Conduct animal experiments to prove scientific and normative nature, and conduct mechanism discussions; Adopt multi-center, large-sample clinical trials to improve rigor and objectivity; Studies were conducted in different regions and populations to analyze applicability and effectiveness, and to explore differentiation and individualization.
