Postural control deficits occur after musculoskeletal injuries, and it may be related to neuromuscular function alteration. While five toed socks may be a viable option for increasing motoneuron pool excitability (MNPE) and balance, there is little scientific research that has been conducted. The purpose of this study is to determine if the application of five toed socks alters MNPE in the lower extremity muscles, if application of those socks alters balance, or if changes in MNPE are related to changes in balance in healthy subjects. Fourteen subjects (5 males, 9 females; age 22.9±3.4 years; height 170.1±7.3 cm, weight 67.6±9.5 kg; BMI 23.4±3.5) performed pre-condition balance test, pre-condition MNPE test, post-condition balance test, and post-condition MNPE test. They repeated the process in different days with randomly assigned sock conditions; five toed socks with textures (FSG), five toed socks without textures (FS), regular socks (RS), and no socks (NS). Percentage changes in H:M ratio between pre- and post- condition and percentage changes in center of pressure (COP) velocity between pre- and post- condition were analyzed. Results showed that there were no significant differencesbetween sock conditions for MNPE (P>.05) or for balance (P>.05). Although there were some correlation between peroneus longus H:M ratio and anterior/posterior direction COP velocity in applying FSG (r=-.60, r2=.36, P=.02) and between tibialis anterior H:M ratio and anterior/posterior direction COP velocity in applying FS (r=-.63, r2=.40, P=.02), it is unable to say if correlations were due to socks or if these physiologic factors are related. Five toed socks with and without textures are not interventions to affect postural control in healthy subjects. Also, changes in MNPE are not likely to be the mechanism of improving balance.
