This randomized controlled study aims to examine long term effects in the skilling up phase over 4 weeks on physical functional performance and strength of mechanical SR-WBV and dance therapy intervention in a frail elderly population.
This study is based on the guideline of falls management exercise programs (FaME; from Skelton and Dinan). The goals: Skilling up: improvement in neuromuscular control, postural control and strengthening of large muscle groups of the lower extremity. Training Gain: improvement of functional abilities. Maintaining the Gains: muscle growth, improvement of bone density and multi-sensory exercises. First, a pilot study was conducted with untrained elderly ("Effects of stochastic resonance therapy on postural control in the elderly population" (KEK Bern: No.228/09, Clinical Trial Registry: NCT01045746). Following, a second pilot study was conducted with frail elderly (Application of Whole-body Vibration With Stochastic Resonance in Frail Elderly: The Effects on Postural Control Clinical Trial Registry:NCT01543243). It was found that the selected chosen form of recruitment (presentation and advertisement) and the measurements methods are suitable for untrained elderly. But for frail elderly the chosen form of recruitment and the measurement methods are not sufficient. For this study, measurement parameters for functional performance and strength will be used. Goals of the study in the skilling up phase: 1. Feasibility 2. Study the effect on physical functional performance 3. Study the effects on muscle strength. The participants will be recruited in Canton Bern - Swizerland and will be randomly allocated to an intervention group or sham group.

Physical Functional Performance
Short physical performance battery (SPBB): The SPBB examines 3 areas of lower extremity function: standing balance (semi-tandem stand, side-by-side stand, full tandem stand), usual walking speed and ability to stand from a chair. These areas represent essential tasks important for independent living. The scores range from 0 (worst performance) to 12 (best performance). SPPB 0-6 is "Poor performance"; SPPB 7-9 is "Intermediate performance; SPPB 10-12 is "High Performance".

Isometric Maximum Voluntary Contraction (IMCV) in Newton (N) Right Knee-extensor
It will be evaluated by isometric MCV (Newton) at 90 degree angle in the knee joint.
