No specific effect of whole-body vibration training in chronic stroke: a double-blind randomized controlled study.

So should I believe this one or the previous one?

To evaluate the effects of whole-body vibration (WBV) training in individuals after stroke.A double-blind randomized controlled study with assessments pre- and posttraining.A university hospital rehabilitation department.Participants (N=31; mean age � SD, 62�7 y; 6-101 mo poststroke) were randomized to an intervention group or a control group.Supervised WBV training (2 sessions/wk for 6wk; 12 repetitions of 40-60s WBV per session). The intervention group trained on a vibrating platform with a conventional amplitude (3.75 mm) and the control group on a "placebo" vibrating platform (0.2mm amplitude); the frequency was 25Hz on both platforms. All participants and examiners were blinded to the amplitudes of the 2 platforms.Primary outcome measures were isokinetic and isometric knee muscle strength (dynamometer). Secondary outcome measures were balance (Berg Balance Scale), muscle tone (Modified Ashworth Scale), gait performance (Timed Up & Go, comfortable gait speed, fast gait speed, and six-minute walk tests), and perceived participation (Stroke Impact Scale).There were no significant differences between the 2 groups after the WBV training. Significant but small improvements (P<.05) in body function and gait performance were found within both groups, but the magnitude of the changes was in the range of normative variation.Six weeks of WBV training on a vibration platform with conventional amplitude was not more efficient than a placebo vibrating platform. Therefore, the use of WBV training in individuals with chronic stroke and mild to moderate disability is not supported.

Comparing the vibration and the control group, we found that vibration significantly improved knee muscle isometric strength

  1. It is simple mate. The people often doing the "research" are idiots. Who do not even understand the difference between Vibration Training and Vibration Therapy. Pivotal or Lineal.

    The rules to each are very specific to the outcome you want.

    eg.... Standing lock legged on a Pivotal unit is for increased circulation and light balancing response only. It has ZERO re-training effects.


    Pretend academic experts hurt possible treatments every day.
