To achieve prospective registration, we recommend submitting your trial for registration at the same time as ethics submission.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The experimental group received a whole body vibration treatment with an increase in the frequency (from 5 to 21 Hz), sets (from 4 to 7) and the time per set (from 30 to 60 s) over 17 sessions (2 sessions per week). Each subject was placed standing on a vibration platform (Galileo Home, Galileo, Novotec, Germany), with a knee flexion of 30 degrees (taking 0 degrees as the anatomical position). In front of the subject was a wall bar that could be grabbed if they were to fall. In each set, the vibration was applied first in the medio-lateral axis (ML, with the feet parallel to the lower edge of the platform) and, then in the antero-posterior axis (AP, with the feet parallel to the longest edge of the platform). These foot positions determined the vibration amplitude, which ranged between 4 and 6 mm peak to peak.

Comparator / control treatment
Each subject was placed standing on a vibration platform. The experimental group received a whole body vibration treatment, with an increase in frequency, sets, and time per set over 17 sessions. The sham group -control- performed the same exercises as the experimental group, but were not exposed to the vibration.
Control group
Placebo
