Botox injections are an incredibly popular way to smooth facial lines and wrinkles — about 5.7 million cosmetic Botox procedures were performed in 2011 alone, according to the American Society of Plastic Surgeons (ASPS). But many people don’t know that Botulinum toxin — the active ingredient in Botox — is helping stroke victims, too. Even before 2002, when the cosmetic use of Botox was approved by the Food and Drug Administration (FDA), doctors used Botox to treat many conditions that weren’t just “skin deep.”
Though Botox happens to be a great way to reduce the appearance of wrinkles, the Botulinum toxin was originally used to treat neurological disorders, explains Allison Brashear, MD, member of the American Association of Neurologists (AAN) and Professor and Chair of Neurology at Wake Forest University School of Medicine in Winston Salem, N.C. One of the diseases that the Botulinum toxin is especially effective in treating is upper-limb muscle spasticity in stroke victims.
Why Botox for Stroke Victims?
A stroke occurs when blood flow to part of a person’s brain is stopped, either by a blood clot or plaque buildup in the arteries. After this happens, it is common for patients to experience muscle and nerve spasticity in their upper body, causing severe muscle toning and stiffness in the hands, elbows and arm.
Muscle spasticity following a stroke can severely inhibit a person’s day-to-day life. “At times, it causes such increased tightness that the hand collapses into itself,” says Gregory Zuercher, DO, a board-certified rehabilitation specialist at St. Joseph Hospital in Nashua, N.H. This can be very painful, and it can also make it difficult to maintain proper hygiene and perform other basic tasks, explains Dr. Zuercher. Activities like putting on clothing, using the restroom and even walking can become nearly impossible — causing stress for both the patient and the caregiver.
Botox is a safe and effective option for treating patients suffering from muscle spasticity. By injecting Botulinum toxin into the muscle, the affected muscles are weakened. “The toxin works where the nerves attach to the muscles, which is called the neuromuscular junction,” says Scott Brown, MD, Chief of the Department of Physical Medicine and Rehabilitation at Sinai Hospital of Baltimore. The nerves in this location are responsible for transmitting the brain signal that causes the muscles to contract. Botox works to block these nerves and “by blocking that transmission, the muscle can’t contract,” Dr. Brown says.
