Abstract

Evaluation of Tensile Strength of the Superficial Digital Flexor Tendon in Horses Subjected to Transcutaneous Electrical Neural Stimulation Therapeutic Regimen

Highlights

  • The superficial digital flexor tendon is one the strongest tendon in the horse body and possesses great tensile strength and low extensibility which serves primarily as a force transmitter and acts as a dynamic amplifier during rapid muscle contraction[5]

  • The ideal tendinous repair must besides morphological reconstitute the injured tissue and preserve the sliding function of the tendon[9], helping to maintain the movement capacity and regain the tensile strength[3,7,8] Despite of frequent application of Transcutaneous Electrical Neural Stimulation (TENS) to subside the clinical inflammatory signs in human athletes and even companion animals referred cases, there is controversy about the actual positive effect of TENS in healing of tendinous tissue and increasing its tensile strength in human and animal cases[5,14], that is why we investigated the ultimate strength to failure point and Corresponding Author: Davood Sharifi, Department of Clinical Sciences, Surgery and Radiology Section, Faculty of Veterinary Medicine, University of Tehran, P.O

  • No treatment was given to control one, whereas treated group was subjected to the transcutaneous electrical neural stimulation (New tens 900c) therapeutic regimens for 10 min daily with intensity of 80 μs, 100 Hz frequency during 14 days
