What is upper limb spasticity?
Upper limb spasticity, sometimes simply referred to as ULS, is a condition which affects an approximate 12 million people throughout the world. Primarily, it affects the range of movement in the arms, including in the elbow, wrist, and fingers, essentially causing uncontrollable spasms in the muscles. ULS is a condition that is impacted by the reaction of the nervous system and causes muscles in the upper limbs to become stiff or to be continually flexed. While not a life-threatening condition, ULS can be very painful to endure, and severely impacts a patient’s quality of life, even making mundane tasks that require ease of mobility to become extremely difficult to perform. In adults, upper limb spasticity is typically resulting from an injury or medical event, further developing due to a pre-existing medical condition. However, there are many treatment options available on the market to patients, that can help improve life with ULS.
Symptoms
While ULS is often triggered by an injury or other medical event, the symptoms may not appear for weeks or even years and may present themselves very gradually. Most generally, the symptoms present themselves as tightness or spasms in the muscles of the upper limbs, and without treatment the muscles can feel as though they are frozen in place. This is why patients should be urged to speak to a physician as soon as spasms or tight limbs become an issue after a medical trauma that may cause upper limb spasticity.
Symptoms of upper limb spasticity include:
- Stiff muscles in the arms;
- Difficulty moving arms or performing activities that were once able to be performed;
- Uncontrollable twitches or movements of the upper limbs;
- Tightness in the muscles in the elbows, wrists, or fingers;
- Arms lock in uncomfortable or unnatural positions, such as pressed against the torso;
- Rotated shoulders;
- Bent elbows or wrists without command;
- Hands involuntarily clench into fists;
- Difficulty or pain when trying to straighten arms, elbows, wrists, or fingers.
Causes
Upper limb spasticity is caused when something occurs that interrupts the natural processes of the nervous system. As nerve cells are responsible for the communication of commands from the brain to various parts of the body, functionality becomes an issue when nerve cells are damaged. Muscles in particular are affected by the signals between the brain and the spinal cord, so when either the brain or spinal cord is injured, ULS may arise.
Causes of upper limb spasticity include:
- A stroke;
- An injury to the brain or spinal cord;
- Diseases that affect the nervous system, such as multiple sclerosis or cerebral palsy.
Treatments
Thankfully, there are treatments available that can help loosen the muscles and keep them from becoming too stiff, allowing more mobility in the upper limbs. Recommended treatment should be based on the severity of ULS and the overall health of the patient. No matter what treatment they receive, physical therapy and exercise is always important, as it helps prevent the joints and muscles from stiffening further, and promotes strength and flexibility.
Treatment options for upper limb spasticity include:
- Braces or splits – these prevent the muscles and joint from getting too stiff by holding them in their correct positions.
- Prescription drugs – drugs like diazepam (Valium), tizanidine (Zanaflex) are helpful because they force the muscles to relax.
- Intrathecal baclofen therapy (ITB) – delivers Baclofen to the intrathecal space of the spinal cord to correct nerve signals, thus preventing spasms.
- Botulinum toxin – Botox or Dysport injections directly into the upper limb muscles can help the stiff and contracting muscles relax.
- Surgery – if no other treatments work, connections between nerves or tendons and the spasming muscles may be cut.
Upper limb spasticity may improve with any of these treatments; however, patients often opt for Botox or other botulinum toxin treatments as the treatment is less likely to disrupt their daily routines.
