Managing Post-Stroke Spasticity

Understanding Spasticity Management Options

• Spasticity after stroke is a velocity-dependent hyperactivity of tonic stretch reflexes that can cause significant pain and functional disturbances in patients, according to the American Heart Association 1, 2
• Treatment typically follows a stepwise approach, beginning with least-invasive modalities and progressing to more invasive options, as recommended by the American Academy of Neurology 1, 3
• First-line approaches include antispastic positioning, range of motion exercises, stretching, splinting, and serial casting, with moderate evidence supporting their effectiveness 1, 2, 3

FDA-Approved Medications for Spasticity

• Tizanidine, baclofen, and dantrolene are FDA-approved oral medications for spasticity treatment in the United States, with baclofen being a guideline-recommended option by the American College of Physicians 1, 2
• Clinical guidelines specifically recommend considering baclofen for spasticity resulting in pain, poor skin hygiene, or decreased function, with high evidence supporting its use 1, 3

Patient-Reported Response Considerations

• Limited evidence exists comparing different pharmacological interventions for post-stroke spasticity, particularly regarding methocarbamol, highlighting the need for further research 1, 2

Treatment Algorithm When Patient Reports Better Response to Methocarbamol

• Consider a trial of methocarbamol if the patient reports better symptom control with methocarbamol and tolerates it well, as suggested by the American Academy of Physical Medicine and Rehabilitation 4
• Maintain non-pharmacological approaches, including antispastic positioning, range of motion exercises, and stretching, regardless of medication choice, with strong evidence supporting their effectiveness 1, 3

Important Considerations and Caveats

• Avoid benzodiazepines (e.g., diazepam) during stroke recovery due to potential negative effects on recovery and sedation, as warned by the American Heart Association 1, 5
• For focal spasticity that remains problematic, consider botulinum toxin injections as an adjunct therapy, with moderate evidence supporting its use 4, 5

When to Consider Alternative Approaches

• If spasticity remains severe despite oral medications, consider more invasive options such as botulinum toxin injections for focal spasticity, as recommended by the American Academy of Neurology 1, 4
• Neurosurgical procedures (selective dorsal rhizotomy or dorsal root entry zone lesion) should only be considered as last-resort options for intractable spasticity, with limited evidence supporting their use 1, 5
