Therapeutic Approaches for Spasticity: Medications and Treatment Modalities

Pharmacological Management of Spasticity

Spasticity, a condition characterized by exaggerated muscle tone and stiffness, often arises due to neurological disorders such as cerebral palsy, multiple sclerosis, or stroke. Proper management is crucial to improve quality of life and mobility.

Commonly Used Medications

• Baclofen: A gamma-aminobutyric acid (GABA) agonist that acts on the spinal cord to reduce muscle overactivity.
• Tizanidine: An alpha-2 adrenergic agonist that helps decrease spasticity by inhibiting excitatory neurotransmitter release.
• Diazepam: A benzodiazepine that enhances GABAergic inhibition, offering relief for severe spasticity cases.
• Dantrolene Sodium: A direct-acting muscle relaxant that affects calcium release from sarcoplasmic reticulum, reducing muscle contractions.

Adjunctive Treatment Modalities

• Physical Therapy: Regular stretching and strengthening exercises help maintain mobility and prevent contractures.
• Botulinum Toxin Injections: Temporary muscle relaxation is achieved through targeted chemodenervation, improving function.
• Surgical Interventions: In severe cases, procedures like selective dorsal rhizotomy or tendon release surgery may be necessary.

Conclusion

Effective spasticity management requires a multidisciplinary approach, combining pharmacological treatments with rehabilitation strategies to enhance patient outcomes.
