Effect Of Modulated Medium Frequency Current Therapy On The Haemodynamic Performance In The Deep Vein Of The Spinal Cord Injury Patients

ObjectivesThe aim of this study was to compare the MMFCT with the Intermittent pneumatic compression in the function of the enhancement the popliteal blood velocity of the patients with spinal cord injury.MethodsTwenty normal volunteers were recruited to the study.The gastrocnemius muscle was stimulated by the MMFCT.In popliteal veins,then the blood flow velocity were measured by ultrasound.Twenty patients with spinal cord injury were recruited to the study.The gastrocnemius muscle was stimulated by the MMFCT.They were also treated by the Intermittent pneumatic compression.In femoral veins,the blood flow velocity were measured by ultrasound.ResultsThe blood velocity of popliteal vein in normal volunteers at rest was 9.5±3.3cm/s,the MMFCT resulted in larger PSV 2.5 times and 2times greater than the baseline.The Intermittent modulation of a single stimulus is prior to the continuous modulation.The MMFCT can also enhance the blood velocity of the patients who lie in bed.The blood velocity of femoral vein in spinal cord injury patients at rest was 6.5±2.7cm/s.The MMFCT resulted in a significant enhancement of the blood velocity.The MMFCT is inferior to the Intermittent pneumatic compression in the capicity of enhancing of popliteal blood velocity for its psv and mean blood flow velocity was slower,but it can empty more blood at the same time.ConclusionThe Modulated Medium Frequency Current Therapy(MMFCT)can enhance the flow of the lower limbs.The capacity of enhancing of popliteal blood of the intermodulation is superior to the continuous modulation.It can also enhance the the flow of patients with spinal cord injury.The MMFCT is inferior to the Intermittent pneumatic compression in the capicity of enhancing of popliteal blood velocity,but it can empty more blood in the same time than the IPC.
