Spasticity
in Multiple Sclerosis
Spasticity
A condition where certain muscles are continuously contracted. This causes stiffness or tightness of the muscles and may interfere with movement, speech and gait. Spasticity is generally caused by damage to the part of the brain or spinal cord that controls voluntary movement.
Many muscles in the human body work as opposing pairs, like the biceps and triceps. When one contracts the other is relaxed. The regulation of these muscles is complex and involves sending information to the muscles and receiving sensory information feedback from them.
In spasticity, this control goes wrong, and both muscles try to contract at the same time. This can lead to the affected limb locking in place with painful muscle cramps developing.
