Unit – 2 – FARADIC CURRENT / FARADISM Quiz PHT 222 Unit – 2 – FARADIC CURRENT / FARADISM

Therapeutic modality – True / False 1. The low frequency currents have an effect on the sensory & motor nerves 2. Each current pulse depolarizes the nerve fiber 3. Faradism denotes tetanic type of current / contractions 4. The faradic current was produced in the past by using the original faradic coil, then by the Smart-Bristow Faradic coil. 5. At present the faradic current is produced by the multivibrator circuit.

Therapeutic modality – True / False 6. The negative electrode is called active & the positive electrode is called passive electrode. 7. Motor point is the point at which the main motor nerve enters the muscle. 8. For treatment purpose the faradic type current is always surged. 9. Faradic current can be interrupted at regular intervals to avoid fatigue of muscles. 10. Chemical effects – It takes place at the electrodes

Therapeutic modality – True / False 11. In faradic stimulation voluntary contraction should be attempted at the same time as the electrical stimulation 12. Generally E.S. is started 5 weeks after the surgeries to prevent tear of the tendon 13. E.S. ↑ muscle strength which is always greater than Voluntary contraction 14. Improved venous & lymphatic drainage is brought about by pumping action of alternate muscle contraction and relaxation. 15. During E.S, the patient sees the whole procedure (Self testing) – It alleviates the fear from the patient towards the current treatment.

Therapeutic modality – True / False 16. In faradic stimulation, the electrodes are placed after due skin preparation. 17. The sensation of the patient’s skin over which the electrodes will be applied are tested for pain sensitivity. 18. The joint over which the muscle so stimulated works remain preferably in a closed pack position. 19. The muscles to be stimulated remains in a partially shortened position (Inner range of muscle work). 20. Generally, this motor points lies at the junction of the upper one third & the lower two thirds of the fleshy belly of the muscle.

Therapeutic modality – True / False 21. In faradic stimulation, stimulation of the muscle at the motor points produce group muscle contraction. 22. Stimulation of the peripheral nerve at points where they become superficial produces contraction only in the isolated muscle. 23. As a general rule the passive electrode selected should be of larger in size compared to the active electrode. 24. As a general rule, the surge interval (Rest period) is always greater than the surge duration (Contraction period). 25. The treatment is either continued for the desired duration or stopped prematurely, if early fatigue occurs.

Therapeutic modality – True / False 26. At the end of faradic treatment session, appearance of mild erythema is normal. 27. For group muscle stimulation of facial muscles, the active pen electrode is placed over the superficial branch of the facial nerve. 28. For individual muscle stimulation of facial muscles, the active pen electrode is placed over the various motor points of the facial muscles. 29. For the stimulation of pelvic floor muscles, if vaginal / rectal electrode can’t be used, then small button electrode is placed over the urogenital / anal region. 30. The intensity or amplitude is gradually increased till a satisfactory muscle contraction is obtained.
