Aim. More ­and ­more, mechan­i­cal vibra­tion exer­cise is ­being ­used in ­both ­sports train­ing ­and reha­bil­i­ta­tion ther­a­py. Many stud­ies ­have report­ed an ­increase in ­the mus­cle per­for­mance of sub­jects ­after ­whole-­body vibra­tion, ­but so ­far ­none ­have eval­u­at­ed ­the pos­sibil­ity to ­improve ­the recov­ery of mus­cle ­strength ­after ante­ri­or cru­ciate lig­a­ment recon­struc­tion. The con­tra­in­di­ca­tions to ­this ­type of treat­ment ­are relat­ed to ­the admin­is­tra­tion of high­er vibra­tion fre­quen­cy ­for peri­ods ­much long­er ­than ­those fore­seen by ­our pro­to­col. However, numer­ous stud­ies ­have ­found ­this treat­ment ­can ­offer ­the ben­e­fit of ­reduced fre­quen­cy ­and inten­sity of ­the elec­tro­myo­graph­ic trac­ing, accom­pa­nied by an ­increase in mus­cle ­strenght sim­i­lar to ­that ­obtained ­after ­strength train­ing ­with over­load. Hormonal ­response ­was ­also ­seen to dif­fer ­from ­that ­after ­strength train­ing ­with over­load ­because of a ­major ­increase in ­blood con­cen­tra­tions of ­growth hor­mone ­and a reduc­tion of cor­ti­sol. The ­aim of ­our ­study ­was to eval­u­ate ­the use­ful­ness of mechan­i­cal vibra­tion in ­the reha­bil­i­ta­tion of ­patients ­who ­received recon­struc­tion of ­the ante­ri­or cru­ciate lig­a­ment.
Methods. In ­this ­study 20 sub­jects ­were ­enrolled ­and ran­dom­ly divid­ed ­into 2 ­groups (10 ­patients ­and 10 con­trol sub­jects). The sub­jects ­received 5 dai­ly admin­is­tra­tions of ­whole-­body vibra­tion (30 Hz fre­quen­cy ­for 1 min­ute) ­over a 2-­week peri­od. Muscle ­force dur­ing exten­sion of ­both low­er ­limbs ­was eval­u­at­ed by iso­met­ric con­trac­tion ­for 5 sec­onds.
Results. Different ­results ­were ­obtained: ­the treat­ment ­group ­showed a ­mean ­increase in mus­cle ­strength ­and in ­mean ­force ­peaks, ­both sta­tis­ti­cal­ly sig­nif­i­cant (p<0.001), com­pared ­with ­the con­trol ­group (p<0.005).
Conclusion. The ben­e­fits ­this treat­ment ­affords, com­pris­ing rap­id admin­is­tra­tion ­time ­and ­ease of appli­ca­tion, indi­cate ­that it ­can be use­ful in ­the reha­bil­i­ta­tion of sub­jects ­who ­receive recon­struc­tion of ­the ante­ri­or cru­ciate lig­a­ment.
