Thermal and non-thermal effects of capacitive-resistive electric transfer application on different structures of the knee: a cadaveric study.Capacitive-resistive electric transfer therapy is used in physical rehabilitation and sports medicine to treat muscle, bone, ligament and tendon injuries.  Capsular, intra-articular and superficial temperature were recorded at 1-min intervals and 5 min after the treatment, using thermocouples placed with ultrasound guidance.  The low-power protocols had only slight capsular and intra-capsular thermal effects, but electric current flow was observed.
