Direct Radiofrequency Application Improves Pain and Gait in Collagenase-Induced Acute Achilles Tendon Injury
Rats of the experimental group treated with RF showed prolonged stance phase, reduced step length, and increased intermediary toe-spread distance and preswing angle to approach normal when compared with rats without RF ((a) , ; (b) , ; (c) , , and (d) , ). When compared rats with or without RF, stance phase increased on day 13 ((a), , ); step length reduced on day 15 ((b), , ); intermediary toe spread distance increased on days 11 and 15 ((c), , , ); preswing angle in RF group increased on days 11 and 15 ((d), , ).
