Gluteal activation and pelvic stability often are decreased in chronic low-back pain sufferers, but the importance of motor control and programming in treatment has not been fully evaluated. This study investigated whether gluteal muscles could be activated more effectively by stimulating the proprioceptive mechanism during walking. Labile support, through wearing "balance shoes," offered facilitation of cerebellovestibular circuits. Electromyographic recordings of gluteus maximus and medius in 15 healthy subjects were made during barefoot and balance shoes walking before and after 1 week of facilitation. Significant increases (P < 0.0002) in gluteal activity and significant decreases (P < 0.01) in time to 75% maximum contraction, demonstrated the value of sensorimotor elicitation of subconscious and automatic responses in muscles often weakened in back pain sufferers.
慢性下背痛患者的臀肌激活和骨盆稳定性通常会降低，但运动控制和编程在治疗中的重要性尚未得到充分评估。本研究调查了在行走过程中通过刺激本体感觉机制是否能更有效地激活臀肌。通过穿着“平衡鞋”提供不稳定支撑，促进小脑前庭回路。在15名健康受试者进行1周促进训练前后，分别在赤脚和穿着平衡鞋行走时记录臀大肌和臀中肌的肌电图。臀肌活动显著增加（P < 0.0002），达到最大收缩75%的时间显著缩短（P < 0.01），这证明了对背痛患者中经常减弱的肌肉进行感觉运动激发潜意识和自动反应的价值。
