Knee osteoarthritis is a chronic joint disease with an impact on quality of life and an increasing incidence what leads to huge costs and burden on the economy.
The present study investigates immediate effects of whole-body vibration on pain, neuromuscular performance, and gait quality in patients with knee osteoarthritis. Eligible patients (n=20) with knee osteoarthritis grade 2 or 3 on Kallgren Lawrence will complete a 5 minute WBV training and a control condition in a randomized order (cross over design). Pain, maximum strength of the leg flexors and extensors, the chair rise test and gait parameters will be measured directly before and after the intervention/control.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Whole-Body Vibration | Experimental | The intervention (IC) will be specified as a five-minute Whole-Body Vibration session. |
|
| Control Condition | Other | The control condition (CC) will conduct the same protocol as the intervention condition. The only difference will be that the vibration plate will be switched off. |

|---|---|---|---|---|
| Whole-Body Vibration | Other | The intervention (IC) will be specified as a five-minute Whole-Body Vibration session. The WBV take place on a side alternating vibration plate (Wellengang, Germany). The patients stand barefoot on the vibration plate on a prescribed position. In this position the amplitude will be 6-7mm. The WBV protocol contains mobilizing sequences with lower frequencies and activating sequences with higher frequencies |
