Therapeutic electrical stimulation in cerebral palsy: a randomized, controlled, crossover trial

Area of Science:

• Neurology
• Pediatrics
• Rehabilitation Medicine

Background:

• Spastic diplegic cerebral palsy (CP) is a common condition affecting motor control in children.
• Gross motor function deficits are a primary challenge for individuals with spastic diplegia.
• Therapeutic electrical stimulation (TES) is a potential intervention, but its efficacy requires rigorous evaluation.

Purpose of the Study:

• To assess the impact of therapeutic electrical stimulation (TES) on gross motor function in children with spastic diplegic cerebral palsy.
• To investigate the effect of TES applied to antagonist leg muscles.
• To compare objective measures of motor function with subjective parental assessments.

Main Methods:

• A 24-month crossover study involving 12 children (ages 5-12) with spastic diplegic CP.
• Random assignment to receive TES for the first or second 12 months, with physiotherapy and home programs unchanged.
• Blind evaluations using motor function tests and video analysis at baseline, 12, and 24 months.

Main Results:

• Objective, blinded evaluations found no significant improvement in motor or ambulatory function with TES.
• Subjective assessments by parents/carers indicated a significant positive effect of TES in 11 out of 12 children.
• A discrepancy exists between objective findings and subjective parental perception of TES efficacy.

Conclusions:

• Therapeutic electrical stimulation (TES) is unlikely to produce significant objective improvements in motor and ambulatory function for children with spastic diplegic cerebral palsy.
• The study highlights the importance of objective outcome measures in evaluating interventions for CP.
• Further research may be needed to understand the basis of parental perception versus objective outcomes.
