Background: Lower limb fractures contribute to the functional impairments and death in people. Decreased Quadriceps muscle strength is a common clinical observation in patients with lower limb injury or because of immobilisation. Interferential Therapy (IFT) and Russian Current(RC) are two medium frequency alternating currents with frequencies of 4kHz and 2.5kHz respectively. The purpose of this study is to find the short term and long-term effects of IFT and RC on Quadriceps muscle strength in patients recovering from post-operative cases of lower limb fractures.
Methodology: 38 participants between age group 16-70 years were selected according to inclusion and exclusion criteria and divided into 3 groups, Group A(n=14) received Interferential Therapy and Conventional Exercises(CE); Group B(n=13) received Russian Current and CE and Group C(n=11) received only CE for 14 days. Patients were given electrical treatment for 6 days and were assessed pre- intervention, 6th day after intervention and the 14th day after intervention. The outcome measures were Numerical Pain Rating Scale (NPRS), Range of Motion and Isometric muscle strength.
Result: For within group analysis the Friedman Test and for between group analysis the Kruskal Wallis Test was used. The intra group comparison was statistically significant with p=< 0.05 while the between group comparison was not statistically significant with p=>0.05.
Conclusion: RC and IFT were not superior to conventional treatment alone.
