EFFECTIVENESS OF THE ASYMMETRIC BYPHASE RECTANGULAR CURRENT CONTINUOUS AND BURST IN THE PAIN OF THE ACUTE ANKLE SPRAIN

Abstract

 Introduction: the asymmetric bypass rectangular current (ABRC) constitutes a very extended method of treat-ment of the pain in the ankle sprain. Objective: we think about to determine if the ABRC is effective in the reduction of the pain in the acute phase of the mentioned lesion, and if exists a statistically significant difference in the analgesia induced by these currents in function of its application in continuous way or burst. Material and method: study analytic, experimental, prospective, longitudinal, randomized (systematic chance) controlled clinical essay with two groups in parallel. Sample: 901 sessions carried out in 96 cases of sprain suffering by individuals belonging to the inferior categories of the Club Basketball Seville (mean 15,58-year-old age SD 2,13). Inclusion approaches: to be diagnosed of ankle sprain I or II, the lesion is in the acute phase and to have an age understood between the 11-21 years. Exclusion approaches: to have been assisted previously in other Physiotherapy centers, to present another associate traumatic pathology, to have been treated by means of immobilization, to present some type of bony ill-ness of degenerative character and/or to suffer some affectation of neurological character that commits the integrity from the nervous system at the ankle. We administer the same treatment in both groups to exception in the current way (burst in one group and continuous in the other). We value the pain by means of the scale VAS before and after applying the current in each session until reaching a pain level 0 in the pretest. Results: mean of pain in the pretest (without considering the current way) 2,99 (SD 1,515) and in the postest 1,45 (SD 1,422), existing a statistically significant difference among both so many stockings when using the test t-Student like that of Wilcoxon (p < 0,05). Mean of decrease of pain when using the current in continuous way 1,17 (SD 0,37) and when using burst current 1,99 (SD 0,60), existing a statistically significant difference among both so many stockings when using the test t-Student like that of Mann-Whitney (p < 0,05). Conclusions: Both treatment modalities are able to produce good analgesia levels existing a statistically significant difference between them. Burst current is better than continuous.
