There are several main types of diadynamic currents, each with slightly different characteristics and therapeutic effects:

Monophase Fixe (MF):

•  Half-wave rectified alternating current.
• Produces a strong vibrating sensation.
• Used for isolated painful muscle conditions and to induce muscle contractions.

Diphase Fixe (DF):

• Full-wave rectified alternating current.
• Has a strong, immediate analgesic (pain-relieving) effect.
• Often used for acute pain with muscle spasms.

Courtes Périodes (CP):

• Alternates between MF and DF currents, typically with a rhythmic change.
• Produces a rhythmic contraction and relaxation effect, which is good for reducing edema and stimulating circulation.
• Used for traumatic pain and conditions with swelling.

Longues Périodes (LP):

• A longer, more gradual alternation between a fixed current and a modulated current.
• Provides a strong analgesic effect due to its ability to prevent accommodation (the body getting used to the stimulation).
• Used for chronic pain and conditions where prolonged pain relief is needed.

Syncopal Rhythm (RS):

• Irregular oscillations with varying frequency and amplitude.
• Primarily induces sedative and analgesic effects. Less commonly used and requires more investigation for its efficacy.
