Abstract: Objective To observe the characteristics of plantar pressure and walking cycle in hemiplegic patients with cerebral infarction. Methods From April, 2017 to November, 2018, 24 hemiplegic patients with cerebral infarction were analyzed the gait with FDM-T Gait Analysis System. The walking cycle, plantar pressure distribution and plantar spatial-temporal parameters were compared between the paralyzed side and the non-paralyzed side. Results Compared with the non-paralyzed side, the standing phase decreased in the paralyzed side (t = -3.343, P < 0.01), as well as the middle stage of standing (t = -3.241, P < 0.01); while the walking phase increased (t = 3.342, P < 0.01), the maximum pressure of the middle foot (t = -2.513, P < 0.05) and the maximum strength time of the middle foot (t = -2.631, P < 0.05) decreased, and foot angle increased (t = 3.072, P < 0.01). Conclusion Standing weight bearing and standing balance training on paralyzed side to extense standing phase, knee joint control training in the middle stage of standing, and correction of metatarsal flexion, pronation and foot deviation, are beneficial to improve walking ability and gait.
