Definition of the method
Normalization to an MVC that is matched to the task in terms of joint angle/muscle length, contraction type, and/or joint angular velocity. This method includes:
- Angle and angular velocity specific maximal dynamic/isokinetic/ isometric voluntary contraction: The peak EMG amplitude(s) from a maximal voluntary contraction with the same muscle action, joint angle, muscle length, angular velocity or rate of change of muscle length as the task of interest.
- Could require tailored MVCs for each task or muscle studied, or a maximal dynamic task to normalize specific phases/angles of the muscle(s) studied.
This method includes:
- Normalizing to maximum voluntary contraction (MVC) provides a relative value useful to compare the magnitude of muscle activity in different tasks or conditions. This represents the activity as a proportion of the maximum capacity of the muscle, as long as the MVC normalization contraction is collected in the same position, same contraction velocity, and contraction types as the task of interest.
