“…Previous research has focused on the role of various parameters of whole-body vibration training for children with spastic cerebral palsy—such as adjusting the vibration frequency and varying the time per session and duration—and other parameters, such as amplitude and wave direction, are usually fixed. In such WBV training, the frequencies were 25–40 Hz (6 min/s, 8 weeks) [ 6 ], 12–18 Hz (9 min/s, 3 months) [ 9 ], 12–18 Hz (9 min/s, 12 weeks) [ 10 ], 20 Hz (6 min/s, 6 weeks) [ 11 ], 5–25 Hz (18 min/s, 8 weeks) [ 13 ], and 13–18 Hz (12 min/s, 6 months) [ 14 ]. Previous studies found improvements in spasticity [ 6 , 10 , 11 ], muscle strength [ 10 , 11 ], gait ability [ 10 , 13 , 14 ], and GMFM88 [ 10 ], but no change in walking balance [ 10 ] or bone [ 14 ].…”
