Therapeutic uses of Low Frequency Current
Low Frequency Current:
An alternating current having a frequency of 0 to 1000hz. Action of Low Frequency Current Stimulation of nerve and muscle To produce muscle contraction and relaxation.
Low frequency alternating current is again divided into four types for therapeutic purpose...
- Faradic current
- Galvanic current
- Sinusoidal current
- Dynamic current
Therapeutic uses of Low Frequency Current:
- Bursitis
- Arthritis
- Relaxation of Muscular spasm
- Increase arrythmia
- Reduction of pain
- Prevention of deep vein thrombosis
- Range of motion
- Pain control
- Nerve stimulation
- Decrease swelling
- Muscle contraction
- Circulatory disorders
- Soft tissue injuries Joint disorders
Effects of Low Frequency Current:
- Inflammation
- Skin lesions and dermatological disorders
- Cardiac pacemakers
- Infection
- Thrombosis
- Active TB or cancer
- Nerve sensitivity
Advantages:
- Low frequency current is used for long distance travelling.
- It is a short duration interrupted current at produces tetanic contraction.
Disadvantages:
- The amount of current that is sent is proportional to the frequency
- Therefore low frequency current is not suitable when large amount of
- Current needs to be transmitted.
- At lower frequency the light flickers more noticeable. Even at the
- Frequency of 60HZ cheaper LED flicker.
