Effects of different wobble boards on lower-limb EMG activity / G. Cimadoro, C. Paizis, G. Alberti, N. Babault. - In: NEUROSCIENCE LETTERS. - ISSN 0304-3940. - 548(2013), pp. 228-232.
Abstract:
This study analysed the equilibrium strategies and EMG activity during postural equilibrium in four different
unstable surfaces. Thirteen team sport males were tested on a FLAT surface and on three different
wobble boards (JAKOBS® with easy multidirectional displacements, FREEMAN with strong multidirectional
displacements and LATERAL with unidirectional lateral displacements). They had to maintain
single-limb stance during 5 s for each condition. The right foot centre of pressure (COP) position and
its variability with concomitant EMG activity of soleus (SOL), tibialis anterior (TA), peroneus longus (PL)
and extensor digitorum longus (EXD) muscles were recorded. Subjects maintained balance by making
seesaw rotations. LATERAL and FREEMAN boards demonstrated significantly greater COP variability than
JAKOBS® and FLAT in both anteroposterior and mediolateral directions. Similarly, PL, EXD, and TA muscles
EMG activity were significantly greater using the LATERAL board, and in some cases using FREEMAN
as compared with JAKOBS® and FLAT. These results highlighted new knowledge about central nervous
system organisation while keeping equilibrium with a predominant anteroposterior control.
