Introduction[edit | edit source]

Diadynamic therapy is an another example for low frequency current rarely used in UK but in mainland Europe has stronger following. it is monophasic sinusoidal current  was developed in the 1950's,by Bernard (a French Dentist). so it is called also Bernard current.The  frequency is operating at 50 Hz with pulse duration 10 msec.[1][2]

There are four different current available for Didynamic current.[3]

  1. Monophase fixe.(MF)
  2. Diphase fixe.(DF)
  3. Courtes periodes.(CP)
  4. Longues periodes.(LP)

Types of Diadynamic current[edit | edit source]

wave Physiological Effect Indication Feeling
DF Full wave alternating current Has strong analgesic effect for short duration Pain with muscle spasm Itching or prickling sensation
MF Half wave alternating current Stimulate muscle contraction Pain without muscle spasm Strong vibration sensation
CP Equal phase of DF and MF are alternating without interval pauses Stimulate circulation and reduce pain Traumatic pain Rapid alternating feeling between DF and MF
LP 10 sec MF followed by 5 sec DF in which intensity and frequency rise then fall long lasting analgesic effect Myalgesia\Neuralgia Strong vibration to little pricking

Clinical application of Diadynamic current[edit | edit source]

Pain spot application[edit | edit source]

The two electrodes are applied as a bipolar technique with the anode applied over pain spot and the cathode adjacent to it.

Nerve Trunk application[edit | edit source]

The two electrodes are placed along the course of the peripheral nerve where the nerve is superficial.

Para-vertebral application[edit | edit source]

The electrodes may be applied on both sides of the spine at the level of the nerve root supplying the painful area.

Vasotropic application[edit | edit source]

The electrodes are applied along the vascular paths affected in the circulatory disorders.

Trans-regional application[edit | edit source]

to treat a joint, electrodes positioned on opposite side of the joint.
