MS Symptom Management: Spasticity

Spasticity is the result of the demyelination of the nerves that regulate muscle tone. People with Multiple Sclerosis (MS) may have spasticity, which occurs when there is a quick stretch to the muscle, causing it to spasm. An example of spasticity would be during the walking cycle when the foot is flexed quickly by the ground; this can apply the quick stretch to the muscle causing the foot to "jump" a few times. The muscle spasm can lead to imbalance or even falls.
