Area of Science:

Background:

• Hemiplegic cerebral palsy (CP) often affects motor function and circulation.
• Interferential current (IFC) is a therapeutic modality used in rehabilitation.
• Understanding the effects of IFC on blood flow (BF) in children with CP is crucial for treatment optimization.

Purpose of the Study:

• To evaluate the short-term impact of sympathetic and peripheral IFC stimulation on blood flow in children diagnosed with hemiplegic cerebral palsy.
• To compare the efficacy of sympathetic versus peripheral IFC stimulation in enhancing blood flow.

Main Methods:

• A randomized controlled trial involving 30 children (8-12 years) with hemiplegic CP.
• Participants were divided into three groups: sympathetic IFC, peripheral IFC, and placebo control.
• Blood volume pulse (BVP) amplitude was measured using plethysmography before, immediately after, and 15 minutes post-20-minute IFC stimulation (80-100 Hz, 10-20 mA).

Main Results:

• Both sympathetic and peripheral IFC significantly increased BVP amplitude compared to pre-stimulation levels (P < 0.05).
• No significant difference in BVP amplitude increase was observed between the sympathetic and peripheral IFC groups.
• The control group showed no significant changes in BVP amplitude (P = 0.995).

Conclusions:

• Both sympathetic and peripheral IFC stimulation effectively improve blood flow in children with hemiplegic CP.
• There is no significant difference in the short-term efficacy between sympathetic and peripheral IFC for enhancing blood flow in this population.
• IFC presents a viable therapeutic option for improving circulation in pediatric hemiplegic CP.
