Abstract

We would like to sincerely express our gratitude to the university of Tehran and faculty of veterinary medicine research council for approval and financial support for this extensive evaluation of tensile strength of the superficial digital flexor tendon in horses subjected to Transcutaneous Electrical Neural Stimulation (TENS) therapeutic regimen Problems statement: The purpose of this study was to determine the effect of TENS on the tensile strength of experimentally traumatized SDFT in horses. Approach: Eight adult castrated horses between 4-9 years-old and 310-395 Kg body-weight were considered. The left fore-limb superficial digital flexor tendon of each horse was splitted longitudinally in the middle portion in full thickness of 10 cm in length using B.P. blade (15 Times strike), then the connective tissue and skin were approximated using No 2 Nylon. Horses were divided into two groups of control and treated with 4 horses each. No treatment was given to control one, whereas treated group was subjected to the transcutaneous electrical neural stimulation (Newtens 900c) therapeutic regimens10 min daily with intensity of 80 µs, 100 Hz frequency for 14 days. After 60 days, the full length of SDFT (20 cm) was removed from the right normal countralaleral and left traumatized tendon of control and treated limbs of all horses to be subjected to test of tensile strength using Zwick/Roell MDTL Machine with speed of 0.07 mM sec−1 having Proportional Integral Deferential (PID) controller. In assessing the variation obtained data was analyzed using paired-t-test. Results: Data of the tensile strength was revealed an average 0.6625 KN for normal SDFT, 0.6375 KN for treated tendon and 0.6175 KN for control tendon .There was significant improvement in regaining tensile strength in treated tendons comparison to control ones in Conclusion: TENS significantly accelerated healing and remodeling of traumatized tendon to regain its tensile strength.
