The purpose of this study was to determine the lower limb muscular synergy and COP trajectory of the carrying and stepping feet during the pitching motion in high-level athletes.
Others
Building a foundation for the prevention of pitching disorders
Muscle synergy: calculated from the muscle activity waveform measured by electromyography
COP: Floor reaction force is measured with a floor reaction force meter and COP is calculated.
The following parameters are calculated using a 3D motion analysis system
Kinematic parameters: joint angle, joint angular velocity
Kinematic parameters: inter-articular forces, joint torque
Interventional
Single arm
Non-randomized
Open -no one is blinded
Self control

Prevention
Device,equipment |
Affixing electrodes for surface electromyography
Attaching markers for 3D motion analysis equipment
Apply for about 90 minutes on the day of measurement.
