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) n = 7, P < 0.05; (b) n = 8, P < 0.05; (c) n = 8, P < 0.01, and (d) n = 8, P < 0.05). When compared rats with or without RF, stance phase increased on day 13 ((a), n = 7, **P < 0.001); step length reduced on day 15 ((b), n = 8, *P < 0.05); intermediary toe spread distance increased on days 11 and 15 ((c), n = 8, **P < 0.001, ***P < 0.0001); preswing angle in RF group increased on days 11 and 15 ((d), n = 8, *P < 0.05).
