Dynamic steady-state balance was assessed using a stabilometer (Stability Platform, Model 16030, Lafayette Instrument Company, Lafayette, IN, USA) containing a 65×107 cm wooden platform with a maximum deviation of ± 15° (Fig 1A and 1B ). EMG data of the tibialis anterior (TA), gastrocnemius medialis (GM), rectus femoris (RF), biceps femoris (BF) and masseter (MA) of the right side were recorded by a wireless EMG system (Noraxon, Scottsdale, USA; 2000 Hz). As preparation, the skin over the muscles was carefully shaved, abraded, and rinsed with alcohol. Bipolar Ag/AgCl surface electrodes (diameter 14 mm, center-to-center distance 20 mm; Noraxon Dual Electrodes, Noraxon, Scottsdale, USA) were positioned in accordance with the European Recommendations for Surface EMG [25 ]. The positions of the EMG electrodes were marked with temporary tattoo ink (MyJagua, Greven, Germany) at T1 to allow identical positioning at T2.

Participants were instrumented with a lower extremity marker set and additional markers on bilateral acromion, sternal notch, and T1. Kinematic data were recorded by a 11-camera Qualisys motion capture system (Qualisys, Gothenburg, Sweden) at 125 Hz. Surface electrodes were placed on bilateral longissimus (2 finger widths lateral from the spinous process of L3). Electromyography (EMG) data were collected using Noraxon wireless EMG system (Noraxon U.S.A, Scottsdale, AZ, USA) at 1500 Hz. A portable treadmill (ICON Health & Fitness, Logan, UT, USA) was used for the walking trials.
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
