Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Patients performed squatting exercises on a vibrating platform over a 12-week period (vibration group; n=12);
the approximate duration of each vibration session was 15 minutes; the frequency of sessions was 3 times per week; the intensity is increased over the 12 week program; the administered one-on-one by a physiotherapist.
the range frequency of the vibration platform was 35-40 Hz ; the training and rest time during the 15 minute sessions was range squats 20-45 seconds, followed by range of rest 20- 45 seconds; the intensity is increased, weekly.
