1. Diadynamic Current

1.Define Diadynamic current. Explain its types, production, and waveform characteristics in electrotherapy. 2.Describe the physiological effects of diadynamic currents on nerve, muscle, and pain modulation. 3.Explain the different modes of diadynamic currents (DF, MF, CP, LP, RS) with their clinical applications. 4.Discuss the indications, contraindications, and precautions of diadynamic current therapy in physiotherapy practice.

Quadrant - IV (MCQs)

Diadynamic currents are produced by:

A: A. Unmodified alternating current B: B. Direct current only C: C. Rectification of sinusoidal alternating current D: D. High-frequency current

Which diadynamic current mode uses half-wave rectification?

A: A. DF (Diphasé Fixe) B: B. MF (Monophasé Fixe) C: C. CP (Courtes Périodes) D: D. LP (Longues Périodes)

A contraindication for diadynamic current therapy is:

A: A. Muscle spasm B: B. Tendinitis C: C. Presence of a cardiac pacemaker D: D. Chronic pain

Diadynamic current is classified as:

A: A. High-frequency current B: B. Medium-frequency current C: C. Low-frequency current D: D. Microwave current

In physiotherapy, what is the primary therapeutic goal of applying diadynamic current to a painful joint?

A: To strengthen atrophied muscles through high‑intensity tetanic contractions B: To mechanically mobilize the joint through muscle contractions C: To heat deep tissues primarily through dielectric heating D: To reduce pain and improve local circulation via low‑frequency modulation

Diadynamic current is classically derived from which type of base waveform?

A: Direct current with constant intensity B: Triangular wave current with variable slope C: High‑frequency pulsed electromagnetic field D: Rectified mains‑frequency sinusoidal current

When selecting parameters for diadynamic current in acute pain, which intensity strategy is most appropriate?

A: Set intensity so low that the patient barely perceives any stimulation B: Use comfortable sensory level, just below motor threshold C: Aim for visible, sustained tetanic contractions of local muscles D: Increase intensity to strong, painful contractions to maximize effect

Which clinical condition is commonly considered an appropriate indication for diadynamic current therapy?

A: Chronic degenerative joint disease with persistent pain B: Confirmed deep vein thrombosis in the limb to be treated C: Presence of a demand‑type cardiac pacemaker near the treatment site D: Presence of a demand‑type cardiac pacemaker near the treatment site

A patient reports strong, unpleasant burning under one electrode during diadynamic current treatment. What is the most appropriate immediate action?

A: Move the electrode directly over a bony prominence to disperse the sensation B: Increase intensity to overcome accommodation C: Stop the current and check electrode contact, size, and skin condition D: Continue the treatment unchanged, as burning is normal
