Effects of Whole-Body Vibration Training Versus Balance Training in Patients With Severe Chronic Obstructive Pulmonary Disease
Effects of Whole-Body Vibration Training Versus Balance Training in Patients With Severe Chronic Obstructive Pulmonary Disease
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.
Inclusion Criteria:

 -  COPD stage III or IV according to the global initiative for chronic obstructive lung
 disease

 -  impaired exercise capacity (6 Minute walk distance of less than 70% of the reference
 value from Troosters et al.)

 Exclusion Criteria:

 -  current acute exacerbation of COPD

 -  carbon dioxide pressure of more than 45 mmHg at rest

 -  any contraindication for vibration Training (e.g. acute deep vein thrombosis)
