Involuntary tightness: This occurs with certain types of strokes, and with spinal cord injuries. Involuntary tightening of the flexor muscles, with intermittent gear as you try to passively straighten a muscle out or extended from the flex position.
Dr. William Goldie
Pediatric Neurology 48 years experience
Spastic tone: In patients with spasticity the arms and legs are stiff and move with difficulty. A very specific form of stiffness will cause a form of release during movement which is similar to the sudden release when a clasp knife releases. The tone can be very tight, then releases, then tightens again. This is the classic findings in spastic cerebral palsy.

What is the meaning of the word spasticity?

Dr. Michele Arnold
Physical Medicine and Rehabilitation 22 years experience
Resistant muscle: Spasticity is complex: it is an increase in muscle resistance, typically more noticeable when a muscle is placed on stretch quickly (it is "velocity-dependent"), creating stiffness/tightness. If untreated it can lead to rigidity or contractures. It is seen most commonly in injuries/illnesses affecting the spinal cord and/or brain. Treatment includes stretching, positioning, bracing, and medication.

Yes: Both drug and non-drug approaches can be very helpful. Physical therapy can direct you in helpful stretching exercises. Medications such as tizanidine, baclofen, clonazepam, diazepam have all been used to address the mechanisms of spasticity.

Will quadriplegic spasticity cause global development delay?

Dr. Rohit Keswani
Physical Medicine and Rehabilitation 25 years experience
No: Quadriplegic spasticity itself should not cause global developmental delay. There are, however, conditions that result in both development delay and quad spasticity so although you may see the two together, one does not necessarily cause the other.

Can anything be taken for spasticity?

1 doctor answer3 doctors weighed in
Dr. Craig Morton
Physical Medicine and Rehabilitation 18 years experience
Yes: True spasticity as opposed to "muscle spasm" usually occurs secondary to a disorder or trauma, such as a spinal cord injury (sci), a brain injury, a tumor, a stroke, multiple sclerosis (ms), or a peripheral nerve injury. Treatments may include, preventative measures, therapy, positioning/orthotics, oral medication, injectable medication, and in some cased surgical intervention.
