Study Notes
Diadynamic Currents in Physical Therapy
- Diadynamic current has two basic forms: Half-Wave Rectification (Monophase Fixe) and Full-Wave Rectification (Diphasé Fixe).
- Half-Wave Rectification (Monophase Fixe) eliminates the second half of each AC cycle, producing a monophasic pulsed current with a frequency of 50Hz.
- Full-Wave Rectification (Diphasé Fixe) duplicates the second half of each AC cycle, producing a direct monophasic current with a frequency of 100Hz.
- Diadynamic modes include Fixed Monophase (MF), Fixed Diphasé (DF), Short Period (CP), Long Period (LP), and Syncopal Rhythem (RS).
- Fixed Monophase (MF) stimulates muscles, produces muscle contraction, and is used for pain treatment without muscle spasm.
- Fixed Diphasé (DF) stimulates autonomic nervous system, improves circulation, and has a strong analgesic effect for a short duration.
- Short Period (CP) involves alternating delivery of equal pauses, increasing blood supply in a traumatic area to reduce pain.
- Long Period (LP) consists of 10 seconds of MF followed by 5 seconds of DF, suitable for neuralgia, myalgia, arthralgia, and chronic pain conditions.
- Syncopal Rhythem (RS) involves fixed durations of MF followed by equal rest durations, used for pain relief, inflammation decrease, muscle re-education, and increased local circulation.
- Diadynamic currents have therapeutic effects including pain relief, improved circulation, decreased inflammation and swelling, muscle re-education, and facilitation of tissue healing.
- Diadynamic currents stimulate sensory nerves leading to pain relief and also stimulate endorphins and encephalins release for pain suppression.
- Diadynamic currents have a relative high DC amplitude, which may increase the risk of skin damage, and treatment time should be limited to avoid skin damage, particularly in cases like Raynaud syndrome.
