OBJECTIVE: To examine the effectiveness of whole body vibration (WBV) on tone,
muscle force, sensation and functional performance in people with multiple
sclerosis.
SUBJECTS: Sixteen people with multiple
sclerosis were randomly allocated to one of two groups. INTERVENTION: Group 1
received four weeks of whole body vibration plus exercise three times per week,
two weeks of no intervention and then four weeks of exercise alone three times
per week. Group 2 were given the two treatment interventions in the reverse order
to group 1. MAIN MEASURES: Ten-metre walk, Timed Up and Go Test, Modified
Ashworth Scale, Multiple Sclerosis Spasticity Scale (MSSS-88), lower limb muscle
force, Nottingham Sensory Assessment and Multiple Sclerosis Impact Scale
(MSIS-29) were used before and after intervention. RESULTS: The exercise
programme had positive effects on muscle force and well-being, but there was
insufficient evidence that the addition of whole body vibration provided any
further benefit. The Modified Ashworth Scale was generally unaffected by either
intervention, although, for each group, results from the MSSS-88 showed whole
body vibration and exercises reduced muscle spasms (P = 0.02). Although results
for the 10-m walk and Timed Up and Go Test improved, this did not reach
statistical significance (P = 0.56; P = 0.70, respectively). For most subjects
sensation was unaffected by whole body vibration. CONCLUSION: Exercise may be
beneficial to those with multiple sclerosis, but there is limited evidence that
the addition of whole body vibration provides any additional improvements.
Further larger scale studies into the effects of whole body vibration in people
with multiple sclerosis are essential.
