Abstract

Aim: The purpose of the study was to compare the efficacy of pulsed electromagnetic field therapy and interferential therapy in treatment of lateral ligament ankle sprains.

Method: 30 patients of age 20-30 years, suffering from Grade I and Grade II ankle sprains in past 2-3 weeks were randomized into 3 equal groups. X-rays were taken to rule out fractures. Group I was treated with pulsed electromagnetic field therapy (PEMF) along with isometric and crepe, Group II was treated with interferential therapy along with isometric and crepe. The modalities were applied for 30 minutes and 12 sessions were given on consecutive days, electrodes were placed on ankle. The outcome was based on self-reported pain using Visual Analogue scale and Manchester foot and ankle disability index. The pain was assessed on 0, 4th, 8th and 12th day using Visual analogue scale. Manchester scores were assessed on 0 and 12th day.

Results: Analyzed by students unpaired t test. Intergroup comparison between group I and group II on 12th day of treatment showed significant improvement with p=0.02. Intergroup comparison between group II and group III, and group I and group III on 12th day of treatment showed highly significant improvement with p=0.000 and p=0.001 respectively. There were more significant improvements in PEMF group as compared to interferential group and controls. In between interferential therapy and controls, the former was more beneficial than latter.

Conclusion: PEMF proved to be more beneficial than interferential therapy in the management of ankle sprains.
