Abstract
Background: Decreased skin temperature observed among children with cerebral palsy is related to increased sympathetic vasomotor tone.The potential of abnormal sympathetic activation in children with cerebral palsy has not received adequate attention. Interferential current electro stimulation changes the velocity of blood flow and the size of blood vessels.
Aim of study:The aim of the current study was to determine the effect of two different applications of interferential current on improving peripheral blood flow in children with spastic cerebral palsy and compare between them.
Participant and methods: Thirty children with spastic cerebral palsy (21hemiplegic and 9diplegic) enrolled in the current study, their age ranged between 8 and 12 years. They were divided randomly into two groups; each group consisted of 15 subjects. The study group (A) received direct stimulation of interferential current while the study group (B) received peripheral stimulation of interferential current. All children received the study protocol for intensity: 10-20 m.A, frequency: 100 Hz and time: 20 minutes. Blood volume pulse amplitude was assessed for both groups using Photo-plethysmograph sensor at big toe pre-treatment, immediate post treatment and 15 minutes post treatment.
Results: Data were statistically analyzed and compared. It was revealed a significant difference in blood volume pulse amplitude between the three measurements in group (A) and (B). There was no significant difference in blood volume pulse amplitude between group (A) and (B).
Conclusion: It can be concluded that both interferential current direct sympathetic stimulation and peripheral stimulation had a useful and important therapeutic effect in improving peripheral blood flow in spastic cerebral palsy children, with no significant difference between the two applications.
