NCT00732017

Brief Summary

The investigators hypothesis is that HVPC with negative polarity diminishes local post-traumatic edema in ankle sprains. Therefore, the objective of this study was to analyze the effect of HVPC on edema secondary to ankle sprains in humans.

Outcome Measures

Primary Outcomes (1)

  • Pain with the visual analogue scale.

    The pain was measured before and at the end of the treatment.

Secondary Outcomes (3)

  • Range of movement (ROM) of plantar and dorsal flexion, inversion and eversion were measured with a goniometer.

    The ROM was measured before and at the end of the treatment.

  • Edema was assessed with measures of ankle girth and volume.

    The edema was measured before and at the end of the treatment.

  • Some descriptive variables of gait such as step and stride length, and the gait speed.

    The variables of gait were measured before and at the end of the treatment

Study Arms (3)

HVPC-

EXPERIMENTAL

This group received standard physical therapy treatment and HVPC with negative polarity.

Device: high voltage pulse stimulation with negative polarity

CG

ACTIVE COMPARATOR

The control group received only standard physical therapy treatment.

Other: standard physical therapy treatment

HVPC+

EXPERIMENTAL

This group received standard physical therapy treatment and HVPC using active electrodes with positive polarity.

Device: Standard physical therapy and HVPC with positive polarity

Interventions

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.

HVPC-

* 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.
