Tone is the natural tension, or contraction, in a muscle that resists stretching. Stroke may cause an abnormal increase in muscle tone, leading to spasticity. Muscle contractions become more intense. The contractions may involve one muscle or a group of muscles.
Does stroke spasticity go away and how long can it last? Spasticity often occurs between 3 and 6 weeks after a stroke, according to research from 2018. The muscular symptoms of spasticity have been shown to continue increasing at 6 months after a stroke.
24.5% of stroke victims developed an increase of muscle tone within 2 weeks after stroke. Patients with spasticity had significantly higher incidences of pain and nursing home placement and lower Barthel and EQ-5D scores than patients with normal muscle tone.
Muscle Tone
Hypertonia is resistance to passive movement, it is not dependent on velocity, can be with or without spasticity. Spasticity is an increase in resistance to sudden , passive movement and IS velocity dependent. The faster the passive movement the stronger the resistance.
As with muscle weakness, changes in muscle tone happen when the area of your brain that controls your muscles is damaged. Spasticity affects up to a third of stroke survivors. It always occurs on the weaker side of your body and may make it difficult to move your limbs.
The modified Tardieu Scale is the most common tool used in the clinical setting to evaluate the muscle tone. The muscle response to a slow and fast stretching will be performed. During the fast stretching, the joint angle in which the muscle responds with difficulty will be collected using an electrogoniometer.
Hypotonicity- a low amount of muscle tone. This is often noted after stroke, when muscles become completely or partially paralyzed. The muscles may no longer feel like they have much or any resistance to being stretched and moved around.
Exercise is a great treatment for spasticity because it sparks neuroplasticity and helps repair the communication between the brain and muscles.
Muscle tone is traditionally defined as 'the tension in the relaxed muscle' or 'the resistance, felt by the examiner during passive stretching of a joint when the muscles are at rest' [1].
Depending on the intensity and the consistency of your workout, it will take 4 to 8 weeks for your muscles to get toned.
If hypertonia is severe, it can cause a joint to become "frozen," which doctors call a joint contracture. Spasticity is a term that is often used interchangeably with hypertonia. Spasticity, however, is a particular type of hypertonia in which the muscles' spasms are increased by movement.
It is caused by damage to the spinal cord that occurs in people with cerebral palsy, traumatic brain injury, stroke or other conditions that affect the brain or spinal cord. In cerebral palsy, the damage isn't reversible, meaning true spasticity doesn't go away on its own.
Regular stretching with a wide range of motion is helpful. Regular exercise of the affected limbs is beneficial. Braces or splints may help to hold a muscle in place and stop it from contracting. Shots of botulinum toxin into spastic muscles in the upper and lower limbs can bring relief.
Though there's no cure for spasticity, these treatments can help alleviate symptoms and improve quality of life. The most effective way to treat spasticity is with a team of healthcare professionals with different specialties. Members of this team may include one or more of the following: Neurologist.
The most rapid recovery usually occurs during the first three to four months after a stroke, but some survivors continue to recover well into the first and second year after their stroke. Some signs point to physical therapy.
High muscle tone in children or adults will often present as appearing rigid, it's generally difficult to move and often involve muscles responsible for flexion, more than extension. In the leg, the knee may have a slight bend, the same will go for the elbow, while wrist and fingers are often fisted.

High tone or hypertonia is increased tension in the muscles which makes it difficult for them to relax and can lead to contractures and loss of independence with everyday tasks.
Hypotonia is low muscle tone or flaccidity that can occur from a stroke. It most commonly occurs right after a stroke and usually subsides but can linger in some patients indefinitely. In this flaccid stage of stroke, one should be careful in positioning the limbs to prevent injury.
Another personality change that occurs after stroke is impulsiveness. This is characterized as the inability to think ahead or understand consequences. Impulsiveness is more commonly seen in people with right-side or a frontal lobe stroke.
