Abstract: Objective To investigate therapeutic efficiency of high frequency electric therapy combined with movement training on osteoarthritis of knee joint.Methods Eighty-five patients were randomly divided into the high frequency electric therapy group (22 cases including 31 knees), movement training group (33 cases including 45 knees) and high frequency electric therapy combined with movement training group (30 cases including 40 knees). All of the patients were assessed with Visual Analogous Scale (VAS) and Lysholm Knee Score Scale (LKSS) before and after treatment.Results Every group had significant improvements compared with selves after treatment. There were significant differences among the three groups (P<0.01).Conclusion Three ways have different therapeutic effect on osteoarthritis of knee, the high frequency electric therapy can slacken the soft tissue, the movement training has reliable effect in the near future; the therapy by high frequency electric therapy combined with movement training is reliable.
