Standard physical therapy and HVPC with positive polarity
A high voltage stimulator with positive polarity was used with a direct pulsed monophasic current, double peak, 5 and 8micros duration and separated by a pulsate interval of 75micros and monopolar application with a dispersive electrode in the lumbar region and two transarticular active electrodes. The intensity of the current was under motor level, that is, just before a visible motor response could be observed. The frequency used was 120pps, in a continuous mode and was applied once a day with thirty-minute duration.

standard physical therapy treatment
"* Initial phase: Application of crushed ice on the ankle for 20 minutes. The subject performed isometric and active exercises of the ankle in all freedom degrees, with no weight bearing.~* Intermediate phase: Application of cryotherapy continued and once mobility was completed and painless, progressive use of weight and reeducation of the walking pattern were initiated. Then, exercises with manual resistance of muscles of ankle and balance in stable surfaces were done.~* Advanced phase: Balance exercises on unstable surfaces as well as strengthening ankle muscles with proprioceptive neuromuscular facilitation techniques and elastic band were performed. At the end, the patient did activities like trotting in S or Z and jumping in all directions."
