Abstract
Objective To investigate the extent between associated reactions and Brunnstrom grading, and quantita-tively analyze neuromuscular control of associated reactions and motion coordination patterns in hemiplegic patients during associated reactions. Methods Movement of paretic low limbs was induced in 54 patients with stroke via associated reactions. Surface electromyographic values were recorded simultaneously from the gluteus medius and adductors of both low limbs. The integrated electromyography (IEMG) ratio of the agonist and the antagonist muscle was calculated. Results The extent of associated reactions alleviated gradually with the elevation of Brunnstrom stage. Impaired antagonist inhibition and coactivation of the agonist and the antagonist muscle during associated reactions were observed in patients after stroke. The agonist/antagonist ratio on the affected side was significantly lower than that on the unaffected side in patients with Brunn-strom Ⅲ-Ⅳ (P<0.05). This did not occur in patients with Brunnstrom Ⅴ～Ⅵ. Conclusions Neuromuscular control of associated reactions was pathological. Impaired antagonist inhibition and excessive coactivation of the agonist and the an-tagonist muscle at a joint contributed to the motor control problems in stroke patients. Associated reactions are a reliable and convenient test to detect motor recovery in patients with hemiparetic stroke.关键词
