Sarcopenia is defined as a phenomenon which the amount of muscle mass in elderly aged 60-70 years is about 20-30% lower than that of the young adults and middle-aged people due to muscle atrophy caused by aging and alteration in muscle itself in aged skeletal muscle. Whole body vibration(WBV) training can be a choice for hospitalized patients who cannot conduct high intensity resistance training.
This study is prospective study. The goal of this study is 1. To investigate the effect of whole body vibration training using vibration platform with tilt table on muscle mass, muscle strength, physical performance in hospitalized older adults with sarcopenia. 2. To demonstrate whether whole body vibration training using vibration platform with tilt table can be useful in hospitalized older adults with sarcopenia who could not perform high intensity exercise.

Subjects enrolled in whole body vibration training group are exposed to side-to-side alternating vertical sinusoidal vibration. Galileo system(Novotec Medical GmbH, Pforzheim, Germany) is used to training. Frequency of whole body vibration is 12Hz and amplitude is 4mm. After 10 minutes of vibration training, subjects rest 3 minutes. Then, additional 10 minutes of training will be given. conventional physical therapy is consisted of passive range of motion exercise and walking exercise.

RECRUITINGBerg balance scale
Change from baseline Berg balance scale to 2 weeks after initial assessment. Berg balance scale \[from 0 to 56 score\] is widely used to assess subjects' ability to control body balance. For '0' score, it means subject cannot maintain his/her own standing balance. For '56' score, he/she can properly keep static/dynamic standing balance.
Time frame: Before intervention / after two weeks intervention
Maximal voluntary isometric contraction at knee
Change from baseline knee extension power to 2 weeks after initial assessment. Using the machine(muscle tester(manual), Lafayett instrument, USA), knee extension power will be measured while subject sit in the chair.
Time frame: Before intervention / after two weeks intervention
10 meter walking test
Change from baseline time when performing 10 meter walking test to 2 weeks after initial assessment. The subject was asked to move 10 meter away from baseline. While subject moved, total amount of time was measured. Then, the time used in first 2 meter movement and last time used in last 2 meter movement was excluded. Finally, total time used in 6 meter movement was measured.
Time frame: Before intervention / after two weeks intervention
Hand grip muscle strength
Change from baseline hand grip strength to 2 weeks after initial assessment. Its assessment is made by Leonardo Mechanograph(Novotec Medical GmbH, Pforzheim, Germany), (unit = N ). For the actual testing procedure, grip strength measurements of the bilateral limb were conducted. The subject was instructed to slowly squeeze the machine. Each measure site was tested one times during 3 seconds. The subjects sit in the chair, maintaining elbow flexed at 90 degree.
Time frame: Before intervention / after two weeks intervention
