Abstract
Ankle contributes a significant role during dynamic movements in the double leg and single leg (SL) balance activities. The subject specific balance performance can be evaluated using SL stance as it has a small base of support, which is able to detect possible impairment during the balance abilities. Hence, the aim of this study was to comprehend the electromyographic (EMG) activity of muscles around the ankle, among healthy adults. This preliminary study was aimed at addressing muscle quantification during SL stance. Eight participants with sports background were recruited. Participants stood on their dominant leg on the Lafayette stability platform in two conditions: with eyes open (EO) and eyes close (EC). Three successful trials for 20 s were recorded respectively. The EMG data from three ankle stabilizer muscles namely Peroneus Longus (PL), Tibialis Anterior (TA) and Gastrocnemius Lateralis (GL) were compared during the SL stance. The results revealed greater balance performance in SL stance during EO compared to EC. PL was seen to be the most active among the three muscles in all conditions. Moreover, PL also demonstrated the highest frequency of total contractions followed by GL and TA during the 20 s task in EO and EC conditions. From this study, we can infer that PL imparts a role of evertor in balance control. © 2022, Springer Nature Switzerland AG.
