| Objective: To explore the characteristics and the relationship between the plantar pressure distribution and standing balance function in poststroke patients with spastic hemiplegia. Methods: From December, 2020 to February, 2022, 40 stroke subjects with spastic hemiplegia (experimental group) and 30 normal subjects (control group) were recruited in the Rehabilitation Department of our hospital. Static and dynamic plantar pressure of subjects in both groups was measured using the Gaitview system, and the standing balance function under eyes open and closed conditions were collected. The parameters of plantar pressure in 8 regions within and between groups were compared. The relationship between the plantar pressure asymmetry and standing balance function was analyzed in the experimental group. Results: In the experimental group, the static and dynamic plantar pressures in the medial and lateral heel of the affected feet were significantly lower than those of the unaffected feet (P<0.05). The static and dynamic plantar pressures in the medial and lateral heel, and the dynamic toe I plantar pressure were significantly lower in the experimental group than in the control group (P<0.05). There was a positive correlation between the trajectory length under eyes closed condition and medial heel pressure difference (R=0.645, P<0.05) and lateral heel pressure difference (R=0.518, P<0.05) between the affected and unaffected side in the experimental group. Conclusion: The plantar pressure of stroke patients with spastic hemiplegia presents the gait asymmetry when walking, and the asymmetry of dynamic plantar pressures in the medial and lateral heel is correlated with the trajectory length. |
