The purpose was to explore the feasibility of whole body vibration (WBV) on polio survivors with/without post-polio syndrome (PPS) by studying its effects on walking speed (10-m walk test), endurance (2-min walk test), pain severity/interference (Brief Pain Inventory [BPI]), sleep quality (Pittsburg Sleep Quality Index), fatigue (Fatigue Severity Scale), leg strength (manual muscle testing and hand-held dynamometry), and muscle cramping (written logs).
Fifteen individuals completed the study, participating in eight sessions in two 4-week blocks. Participants started with ten 1-min vibration bouts/session, increasing to 20 min. Low (amplitude 4.53 mm, g force 2.21) and higher (amplitude 8.82 mm, g force 2.76) intensity blocked intervention occurred in random order crossover design. Blinded testing ensued before/after intervention blocks and at follow-up.
No study-related adverse events occurred. Participants starting first with higher intensity intervention improved in walking speed (p = 0.017). BPI pain severity significantly improved (p = 0.049) after higher intensity intervention. No significant changes were found after low intensity vibration or in other outcome measures.
WBV appears to be a safe exercise for this population. Long-term use in polio survivors needs to be researched, particularly in reducing barriers to participation to promote the physical aspects of health.
通过研究全身振动（WBV）对行走速度（10米步行测试）、耐力（2分钟步行测试）、疼痛严重程度/干扰（简明疼痛量表[BPI]）、睡眠质量（匹兹堡睡眠质量指数）、疲劳（疲劳严重程度量表）、腿部力量（徒手肌力测试和手持测力计）以及肌肉痉挛（书面记录）的影响，探讨其对伴有或不伴有小儿麻痹后遗症（PPS）的小儿麻痹症幸存者的可行性。
15名个体完成了该研究，在两个为期4周的阶段中参加了8次训练。参与者从每次训练10次1分钟的振动回合开始，逐渐增加到20分钟。低强度（振幅4.53毫米，重力2.21）和高强度（振幅8.82毫米，重力2.76）的分组干预采用随机顺序交叉设计。在干预阶段前后以及随访时进行盲法测试。
未发生与研究相关的不良事件。首先开始进行高强度干预的参与者在行走速度方面有所改善（p = 0.017）。高强度干预后，BPI疼痛严重程度显著改善（p = 0.049）。低强度振动后或其他结局指标未发现显著变化。
全身振动对该人群似乎是一种安全的运动方式。小儿麻痹症幸存者长期使用全身振动的情况需要进一步研究，特别是在减少参与障碍以促进健康的身体方面。
