Effectiveness of electrical stimulation after administration of botulinum toxin in children with spastic diplegic...

Area of Science:

• Pediatric Neurology
• Rehabilitation Medicine
• Movement Disorders

Background:

• Spastic diplegic cerebral palsy (SDCP) is characterized by increased muscle tone, affecting mobility.
• Botulinum toxin A (BTX-A) injections are used to reduce spasticity in affected muscles.
• Electrical stimulation is a potential adjunct therapy to enhance BTX-A effects.

Purpose of the Study:

• To evaluate the effectiveness of electrical stimulation combined with BTX-A injections.
• To compare outcomes between BTX-A injection with electrical stimulation versus BTX-A injection alone in children with SDCP.

Main Methods:

• A randomized study included 38 children with SDCP (mean age 6.3 years) with calf muscle spasticity (Modified Ashworth Scale 1+ to 3).
• Participants received either BTX-A injection plus electrical stimulation (n=19) or BTX-A injection alone (n=19).
• Evaluations included Modified Ashworth Scale (MAS), Penn Spasm Frequency Scale (PSFS), Gross Motor Function Measure-88 (GMFM-88) Dimensions D and E, and walking velocity.

Main Results:

• Both groups demonstrated a significant decrease in lower extremity spasticity (p<0.05).
• No statistically significant differences were observed between the groups in MAS, PSFS, GMFM-88 scores, or walking velocity.

Conclusions:

• Both treatment approaches (BTX-A with or without electrical stimulation) were beneficial in reducing spasticity.
• Electrical stimulation applied to gastrocnemius motor points did not offer additional advantages over BTX-A injection alone in this pediatric SDCP cohort.
