Aim of this study is to compare the effects of whole-body Vibration Training versus conventional Balance Training on Balance performance, gait quality and exercise capacity in patients with severe chronic obstructive pulmonary disease. Patients will be recruited during a 3-week inpatient pulmonary rehabilitation program and will be randomized into one of two intervention groups. On top of a standardized endurance and strength Training program (5 days per week) patients in both groups will perform an additional Balance Training (on 3 days per week). Patients in both Groups will perform the same 4 different Balance exercises (2x1 Minute each): dynamic squats with closed eyes, heel raise, semi-Tandem stance and single leg stance but on a different surface. The Vibration Training Group will perform the exercises on a side-alternating Vibration platform (Galileo) at frequencies between 15 to 26 Hertz and the control Group will perform exercises on instable objects like Balance pads. The degree of difficulty in both Groups will be individually adjusted and will be progressively increased, if possible.

Change in Balance Performance during semi Tandem stance
patients stand still for 10 seconds with closed eyes on a force platform that measures absolute path length of the center of force.
Time frame: measurement on Day 1 and 21
Change in muscle power during counter movement jump
patients jump on a force platform as high as possible. The Outcome is Watt per Kilogram Body weight
Time frame: measurement on Day 1 and 21
Change in performance of the 5-Repetition-Raise-Test
Patients try to perform 5 repetitions of standing up and sitting down from a chair with crossed arms on a force platform as quick as possible
Time frame: measurement on Day 1 and 21
Change in performance of the 1-Minute-Chair-Rise-Test
Patients try to perform as many repetitions as possible of standing up and sitting down from a chair with crossed arms on a force platform during 1 minute
Time frame: measurement on Day 1 and 21
Change in Peak muscle strength of the knee Extension muscles
isometric peak torque of the knee extensor muscles are measured in 90° knee angle
Time frame: measurement on Day 1 and 21
Change in Peak muscle strength of the knee Flexion muscles
isometric peak torque of the knee flexor muscles are measured in 90° knee angle
Time frame: measurement on Day 1 and 21
Change in 6-minute Walk Distance
patients are advised to walk as far as possible on a 30m track
Time frame: measurement on Day 1 and 21
Change in 4m Gait Speed Test
patients have to walk 4 meters at their usual Speed. Outcome is the average Speed during the 4m walk.
Time frame: measurement on Day 1 and 21
Change in step symmetry during 20m walking
Patients walk 20m while wearing the Mc Roberts move test device (triaxial accelerometer) which performs a gait analysis
Time frame: measurement on Day 1 and 21
Change in Hospital anxiety and Depression scale
the Hospital anxiety and Depression scale is a questionnaire that evaluates signs of anxiety or depression
Time frame: measurement on Day 1 and 21
Change in balance performance during Romberg stance
patients stand still for 10 seconds with closed eyes on a force platform that measures absolute path length of the center of force.
Time frame: measurement on Day 1 and 21
Change in Balance Performance during 1-leg stance
patients stand still for 10 seconds with closed eyes on a force platform that measures absolute path length of the center of force.
Time frame: measurement on Day 1 and 21
