| Proprioception is closely related to motor control, balance, and coordination, and proprioceptive deficits can lead to abnormal movement patterns such as abnormal gait and uncoordinated movements, and significantly increase the risk of falls in stroke patients. Spatiotemporal asymmetry of limb movements in stroke patients may be related to muscle weakness and sensory dysfunction (both cutaneous and proprioceptive), and the ultimate goal of proprioceptive training is to improve movement patterns and limb spatiotemporal symmetry. Currently, traditional rehabilitation methods for post-stroke proprioception disorders are mainly divided into peripheral and central interventions, with peripheral interventions including proprioceptive neuromuscular facilitation (PNF), and the central interventions include transcranial direct current stimulation (tDCS) and repetitive transcranial magnetic stimulation (rTMS). Research has shown that a form of proprioceptive training that combines passive and active movements is the most effective way to improve motor function. In recent years, training based on the principle of error augmentation (EA) has gradually gained attention as an emerging method. This method uses proprioceptive reorganization and sensorimotor adaptation as the mechanism, strengthens the active participation of the patient, and combines active and passive participations to promote the functional recovery of the patients, and has significant efficacy in improving the proprioceptive and motor functions of patients with stroke, especially in the improvement of spatial-temporal symmetry of the limbs. In this paper, we will briefly review the principle mechanism of EA and its application in the proprioceptive training of stroke patients, aiming to provide new ideas and references for the clinical rehabilitation of stroke. |
