Study Arms (2)

Vibration Group

EXPERIMENTAL

The vibration group was included in the low frequency (25 Hz), low amplitude (2mm), fixed six-week training on two non-consecutive days of the week.

Device: Whole-body vibration training

Control Group

NO INTERVENTION

No training was given to the control group.

Interventions

Whole-body vibration trainingDEVICE

Whole body vibration (WBV) is a form of treatment that has been shown to have an important role in increasing neuromuscular performance, improving muscular strength, balance. The technique involves standing and holding positions, or performing prescribed exercises, on a platform that is vibrating at a programmed frequency, amplitude, and magnitude of oscillationWhole-body vibration (WBV) is a therapeutic method that exposes the entire body to mechanical oscillations while the patient stands or sits on a vibrating platform.
