MCML Assessment and Treatment of Abnormal Muscle Tone Practice Test 2026 - Free Practice Questions and Study Guide

Spasticity can be advantageous when it provides a base of support for postural control. When tone is increased in the antigravity muscles, the legs can become stiffer and better aligned, creating a stable frame that resists sway and helps maintain an upright posture. This added stiffness can make standing and standing-to-sitting transfers more stable by reducing the degrees of freedom the person has to actively control. Of course, the same tone can limit fine movement and range of motion if excessive, but in terms of postural stability, the extra tone can serve as a helpful support for maintaining balance.
