This randomised double-blinded controlled cross-over pilot study examined feasibility and preliminary effects of stochastic resonance whole-body vibration training applied in long term care elderly.
Nine long term care elderly were recruited and randomized to group A (6 Hz, Noise 4 SR-WBV/ Sham) or B (Sham / 1 Hz, Noise 1 SR-WBV). Feasibility outcomes included recruitment rate, attrition, adherence and safety. Physical performance outcomes focused on the Expanded Timed Get Up-and-Go (ETGUG) test, the Short Physical Performance Battery (SPPB), and lower extremity muscle strength. Of 24 subjects initially approached 9 started and 5 completed the study resulting in 37.5 recruitment, 44.4 attrition and 81.7 % adherence rates. No adverse events were reported. There is more evidence of improved performance levels in the SR-WBV treatment group with significant differences in average change for isometric rate of force development (p = 0.016 left leg; p = 0.028 right leg). No statistical significance was reached for other parameters.
The findings of this study indicate that the used training protocol for long term care elderly is feasible, however, requires more closely monitoring of participants; e.g. needs protocol modifications that target improved compliance with the intervention in this setting. SR-WBV shows beneficial effects on physical performance for those adhering to the intervention.

本随机双盲对照交叉试验性研究探讨了随机共振全身振动训练应用于长期护理老年人的可行性及初步效果。
招募了9名长期护理老年人，并随机分为A组（6赫兹，噪声4随机共振全身振动/假干预）或B组（假干预/1赫兹，噪声1随机共振全身振动）。可行性指标包括招募率、损耗率、依从性和安全性。身体机能指标重点关注扩展计时起立行走测试（ETGUG）、简短身体机能量表（SPPB）以及下肢肌肉力量。最初接触的24名受试者中，9人开始参与研究，5人完成研究，招募率为37.5%，损耗率为44.4%，依从率为81.7%。未报告不良事件。有更多证据表明随机共振全身振动治疗组的机能水平有所改善，等长肌力发展速率的平均变化存在显著差异（左腿p = 0.016；右腿p = 0.028）。其他参数未达到统计学显著性。
本研究结果表明，所采用的针对长期护理老年人的训练方案是可行的，然而，需要更密切地监测参与者；例如，需要修改方案，以提高在此环境下对干预措施的依从性。对于坚持干预的人来说，随机共振全身振动对身体机能有有益影响。
