Post-Stroke spasticity made
simple
Among the many serious consequences of
a stroke, one of the most physically debilitating is "spasticity," or
uncontrolled muscle tightness often accompanied by pain and reduced function,
such as difficulty walking and using hands. "Restricted movement can make
day-to-day life a struggle," said Dr. Anne-Louise Lafontaine, a neurologist and
director of the Movement Disorders Clinic of the McGill University Health
Centre.
The extent of spasticity varies
greatly between patients. Some patients have very subtle spasticity, such as
bent fingers or a specific uncontrolled movement when performing a particular
task. Other patients are have severe spasticity, not being able to dress
themselves or perform even the simplest activity of daily living.
"All patients deserve evaluation for their spasticity regardless of the extent
of the disability," said Dr. Lafontaine. "We have effective treatments that can
help improve function in many patients. These treatments can be effective even
years after the stroke in selected cases."
Dr. Saty Sharma, physiatrist
specializing in spasticity rehabilitation at Sunnybrook and Women's College
Hospital in Toronto, Ontario [verify title] urges caregivers to be watchful for
potential spasticity in a stroke patient. "Patients have a multitude of issues
after stroke and may not be able to recognize the reasons for their pain or
restricted function. In such case, a caregiver, a family member and a
physiotherapist should alert the doctor to potential spasticity and ask for
referral to a spasticity clinic," he said.
It is important to make a distinction
between focal and generalized spasticity. Focal spasticity affects a smaller
part of the body, such as a hand or an extremity. Generalized spasticity
affects greater areas of the body or the whole body. The approach to treatment
will vary depending on whether you (or your loved one) suffer from focal or
generalized spasticity.
"The treatment usually involves a
combination of physiotherapy, occupational therapy and if need be, a medical
treatment," explained Dr. Lafontaine. "For focal spasticity, I use Botox as the
first line because it is simple, effective and has virtually no side effects.
It is injected at first every three months. In some patients, injections twice
a year can maintain the goals of therapy. The effect can be cumulative. So, it
might take two or three injections to see the full extent of improvement."
"For generalized spasticity, there are several oral medications such as
Baclofen, Diazepam or Tizanidine. These medications relax muscle contractions
and improve the range of motion. Unfortunately, because they enter blood
circulation, these medications cause side effects such as drowsiness and muscle
weakness. So, the decision to use them is based on whether the benefits
outweigh the side effects in a particular patient."
"In our rehabilitation unit, we like to see patients alert and participating in
physiotherapy and other activities," said Dr. Sharma. "It helps their recovery.
So, we carefully monitor and adjust the doses of oral medications. For focal
spasticity we use Botox, which does not produce these side effects."
The extent to which spasticity can be
rehabilitated varies between patients. Some of the factors that may affect the
success are the patient's age, the extent of brain damage, the ability of the
brain to repair itself and the time after stroke. However, "it is very
difficult to predict the degree of success for a particular patient," said Dr.
Lafontaine. "Some patients achieve a reasonable success with treatment of
spasticity even years after the stroke while others see a lesser improvement or
not at all. The best is to start treatment as soon as possible."
Spasticity deserves the same attention as other stroke disabilities. Do not be
embarrassed or think you have to live with this limitation. Tell your doctor
which disabilities bother you and be as specific as you can. Ask for help.
