Correlation Between Selected Haematological and Doppler Ultrasonic Parameters in Peripheral Arterial Diseased Patients

July 26, 2021 updated by: Heba Ahmed Ali Abdeen, Cairo University

Correlation Between Selected Hematological and Doppler Ultrasonic Parameters After Electrical Stimulation in Peripheral Arterial Diseased Patients

Forty patients of both sexes, aged between 50 and 60 years, were chosen from an outpatient vascular clinic in the El Sahel Education Hospital. Patients have been examined and referred to by a vascular specialist.

Study Overview

Detailed Description

The participants were divided randomly into two groups of equal numbers. The study group got low-frequency TENS (4 Hz frequency, pulse duration 200 μs) which was administered through surface electrodes for 45 min per session, supramaximal stimulation for T12, L1, and L2 sympathetic ganglions that innervate the lower extremity for 45 min per session, three times per week and for 12 weeks. Control Group that received placebo stimulation as provided by the same TENS device but with a zero volt after 10 s of stimulation.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Active Comparator: study group(A)
Group (A) included 20 patients who received low-frequency TENS (frequency 4 Hz, pulse duration 200 μs) for 45 min per session, three times per week, and for 12 weeks.
The Patients in group (A) received low-frequency TENS (frequency 4 Hz, pulse duration 200 μs,burst mode) was be applied through 2 output channels surface electrodes with an E2 TENS device, for 45 min per session, supramaximal stimulation to sympathetic ganglions in T12, L1, and L2, which innervate the lower extremity . For 45 min per session, three times per week, and for 12 weeks.
Other Names:
  • TENS
Sham Comparator: Control group(B)
The control group(B) included 20 patients who received placebo TENS stimulation but with a voltage level falling to zero after 10 s of stimulation
The Patients in group (A) received low-frequency TENS (frequency 4 Hz, pulse duration 200 μs,burst mode) was be applied through 2 output channels surface electrodes with an E2 TENS device, for 45 min per session, supramaximal stimulation to sympathetic ganglions in T12, L1, and L2, which innervate the lower extremity .
