Summary

Botulinum toxin (BTX) therapy can temporarily improve gait in spastic paraparesis patients by reducing adductor muscle hypertonicity. However, transient effects suggest compensatory mechanisms limit long-term benefits.

Area of Science:

  • Neurology
  • Physical Medicine and Rehabilitation

Context:

  • Spastic paraparesis is a neurological condition characterized by lower limb spasticity.
  • Gait disturbance, particularly scissors gait, is a common symptom due to adductor muscle hypertonicity.

Purpose:

  • To evaluate the efficacy of botulinum toxin (BTX) injections in managing spastic paraparesis.
  • To assess the impact of BTX on gait abnormalities and muscle tone.

Summary:

  • Three patients with spastic paraparesis received BTX injections.
  • Two patients with adductor hypertonicity showed transient gait improvement after BTX.
  • One patient with normal adductor tone experienced worsened gait after quadriceps BTX injection.

Impact:

  • Botulinum toxin may be a useful therapeutic option for selected spastic paraparesis cases, specifically for alleviating adductor muscle hypertonicity.
  • Understanding compensatory mechanisms is crucial for optimizing BTX treatment duration and effectiveness.
