How will the nature of the movements change if one of the antagonist muscles ceases to function?

Movement in any joint is provided by at least two muscles acting in opposite directions. Such muscles are called antagonists (e.g., flexors and extensors). With each movement, not only the muscles that perform it are tensed, but also their antagonists, which counteract traction and thereby give the movement accuracy and smoothness. If the antagonist muscle malfunctions, the accuracy of the movements is lost.
