Description
Summary:The association between muscle tone and postural sway characteristics during standing was investigated in 27 healthy men aged 17-31 years. Frequency of muscle oscillations as an indicator of the tone, logarithmic decrement of the dampening of muscle oscillations as an indicator of the elasticity, and stiffness of the medial gastrocnemius (MG) muscle were measured bilaterally using a hand-held Myoton-3 device (Estonia). Postural sway of the centre of foot pressure during 30 s quiet bipedal standing was recorded using a Kistler force plate. As compared to the lying position, at standing on stable ground (SG) as well as on unstable ground (USG) (balance pad) the frequency of muscle oscillations was greater and so was stiffness but no significant differences for the logarithmic decrement of the dampening of muscle oscillations were noted. A greater coefficient of variation at standing on SG and USG as compared to the lying position for frequency of muscle oscillations, for stiffness, and for the logarithmic decrement of the dampening of muscle oscillations was found.
