Leg & Foot Spasticity

Also known as: muscle spasticity, flexion contractures, leg spasms, lower limb spasticity.

What is upper extremity spasticity?

Lower extremity spasticity refers to increased muscle tone and hyperactive reflexes in the legs and feet. It is usually due to a problem with motor nerves in the brain, and can be caused by cerebral palsy, stroke or traumatic brain injury.

What causes upper extremity spasticity?

As noted above, lower extremity spasticity occurs from damage to lower motor nerves (in the brain). It is frequently the result of another medical condition, such as cerebral palsy, stroke, or traumatic brain injury.

What are the symptoms of upper extremity spasticity?

Spasticity of the upper extremity ranges from mild to very disabling. The affected muscles may be over-active and cause joint contractures (stiff joints). The most common presentation includes a stiff legs that can't be bent or separated (extensor spasm), or contracted legs that can't be straightened out (flexor spasm). There are also spasms that present as twitching or tapping of the foot.

The position of the weak and spastic leg/foot creates a functional, hygenic and cosmetic problem.

What are upper extremity spasticity care options?

Therapy, medication and surgery are usually used together to address upper extremity spasticity.

In all patients with upper extremity spasticity, therapy to prevent contractures (tight joints) is necessary.

  • Therapy for spasticity includes stretching tight muscles and joints, strengthening weakened muscles and using splints to improve and maintain good joint position.
  • Medication can also be prescribed to treat spasticity.
  • Surgery can be considered to improve mobility, self-care, hygiene, and the appearance of the affected arm/hand, but is usually only a part of the care plan.
