As adults with cerebral palsy (CP) are surviving longer, interventions are needed to reduce spasticity and increase strength to improve mobility and life quality. Adults with CP are lacking a form of independent exercise that allows them to maintain or improve their ambulation skills. A new approach to increase muscle strength and flexibility called whole-body vibration (WBV) was assessed.
Using an individualized frequency (I-Freq) approach to WBV therapy the acute effects on gait in adults with CP was measured. In this study, eight adults with CP (age 20-51 years, two female) participated in two testing sessions: session one determined each individual's I-Freq; and session two included a 3D gait analysis before and after a WBV treatment. The WBV was administered in five, one minute bouts of vibration followed by one minute of rest.
Following WBV exposure subjects experienced a significant increase in walking speed (P=0.047), stride length (P=0.017) and dynamic ankle range of motion (P=0.042).
These data show that acute WBV treatments at I-Freq can improve measures of gait and mobility in adults with CP, however, future should assess potential long-term improvements.
随着成年脑瘫患者的寿命延长，需要采取干预措施来减轻痉挛并增强力量，以改善活动能力和生活质量。成年脑瘫患者缺乏一种能让他们维持或提高步行技能的独立锻炼方式。对一种名为全身振动（WBV）的增强肌肉力量和灵活性的新方法进行了评估。
采用全身振动疗法的个性化频率（I-Freq）方法，测量其对成年脑瘫患者步态的急性影响。在本研究中，八名成年脑瘫患者（年龄20 - 51岁，两名女性）参加了两次测试：第一次测试确定每个人的个性化频率；第二次测试包括在全身振动治疗前后进行三维步态分析。全身振动以五次、每次一分钟的振动进行，每次振动后休息一分钟。
接受全身振动后，受试者的步行速度（P = 0.047）、步幅（P = 0.017）和动态踝关节活动范围（P = 0.042）显著增加。
这些数据表明，在个性化频率下进行急性全身振动治疗可改善成年脑瘫患者的步态和活动能力指标，然而，未来应评估其潜在的长期改善效果。
