The other group received Interferential current (IFC) treatment from IFC machine (ENRAF-NONIUS), by a four-pole method with Dipole vector (automatic).
Table: Showing mean +- SD and P value of visual analog scale (VAS), Penn shoulders scale (PSS), and shoulder pain and disability index (SPADI) measured pre and post treatment in LASER and Interferential current Group.
Physiological and therapeutic effects of interferential currents
are expressed by: control of pain (pain gate theory), motor stimulation (muscle contractions production), edema and inflammation reduction (by improving the local blood and lymphatic circulation) and muscular spasms reduction and relief.
An investigation into the analgesic effects of different frequencies of the amplitude-modulated wave of interferential current
therapy on cold-induced pain in normal subjects Arch Phys Med Rehabil 2003:84; 1387-94.
Conclusion: Interferential current
therapy is an effective treatment method in chronic MPS.
39) demonstrated that interferential current
(IFC) was effective in alleviating both pain and disability in patients with chronic back pain due to previous multiple vertebral osteoporotic fractures.
The initial treatment program consisted of Interferential Current
followed by Microcurrent application along the anterior shoulder in a direction parallel to the fibers of the anterior glenohumeral capsule.
Treatment consisted of the use of physiotherapy modalities, including interferential current
, ultrasound, heat and ice for pain and inflammatory control and progressive restoration of motion in the left ankle.
A sports specific rehabilitation protocol was employed to re-establish wrist extensor strength and interferential current
and ice were used to control pain and residual inflammation.
Electrotherapeutic agents such as TENS, interferential currents
, and diadynamic currents may have beneficial effects on pain, joint function, and quality of life.
