The purpose of this study was to determine if a balance and strength training program could improve equilibrium and strength in persons with stage I-III Parkinsonism. Subjects were pre-tested on strength and balance (EquiTest) and randomized into either a treatment or a control group. The treatment subjects participated in 10 weeks of lower limb strength training and balance exercises designed to challenge a stable posture and increase limits of stability. Both groups were then posttested on balance, knee flexion, knee extension, and ankle inversion strength. Subjects who received strength and balance training demonstrated significantly improved equilibrium and modest gains in knee flexion and extension strength, while the control group showed no improvement in conditions of destabilizing balance environments and significant declines in strength. Results indicate that 10 weeks of balance and strength training lead to improved equilibrium by producing positive changes in two different control mechanisms. One, training altered the ability to control the motor system when vestibular cues had to be the primary source of reliable feedback; and two, training helped subjects to override faulty proprioceptive feedback and utilize reliable visual or vestibular cues.
本研究的目的是确定平衡与力量训练计划是否能改善I - III期帕金森病患者的平衡能力和力量。对受试者进行力量和平衡（EquiTest）预测试，并随机分为治疗组或对照组。治疗组受试者参加为期10周的下肢力量训练和平衡练习，旨在挑战稳定姿势并增加稳定性极限。然后对两组进行平衡、膝关节屈曲、膝关节伸展和踝关节内翻力量的后测试。接受力量和平衡训练的受试者表现出平衡能力显著改善，膝关节屈伸力量有适度增加，而对照组在平衡环境不稳定的情况下没有改善，力量显著下降。结果表明，10周的平衡与力量训练通过在两种不同的控制机制中产生积极变化，从而改善了平衡能力。其一，当前庭线索必须成为可靠反馈的主要来源时，训练改变了控制运动系统的能力；其二，训练帮助受试者克服错误的本体感觉反馈，并利用可靠的视觉或前庭线索。
