PAM Electrotherapy Techniques

Question 1

What is the primary purpose of electrotherapy in physical therapy?

Accepted Answer

To stimulate muscles and reduce pain.

Answer

Electrotherapy uses electrical currents to achieve therapeutic effects in physical therapy. Its primary purposes include stimulating muscle contractions to prevent atrophy or improve strength, and modulating pain pathways to provide relief. It can also help improve local circulation and reduce muscle spasms.

Question 2

Which of the following is commonly used in electrotherapy for pain relief?

Accepted Answer

Transcutaneous Electrical Nerve Stimulation (TENS).

Answer

Transcutaneous Electrical Nerve Stimulation (TENS) is a widely used electrotherapy modality specifically designed for pain relief. It works by delivering low-voltage electrical currents through electrodes placed on the skin, which can either block pain signals or stimulate the release of endorphins. While EMS stimulates muscles, TENS is primarily focused on sensory nerve stimulation for analgesia.

Question 3

When should electrotherapy not be used?

Accepted Answer

Answer

Electrotherapy should not be used on areas with broken skin because it can increase the risk of infection and cause discomfort or skin irritation. The altered skin impedance can also lead to uneven current distribution, potentially causing burns. Maintaining skin integrity is essential for safe and effective electrotherapy application.

Question 4

What does interferential current therapy do in electrotherapy?

Accepted Answer

It helps reduce pain, inflammation, and muscle spasms.

Answer

Interferential current (IFC) therapy uses two medium-frequency currents that interfere with each other to create a deeper, more comfortable current within the tissues. This modality is effective in reducing pain by stimulating nerve fibers, decreasing inflammation by promoting fluid exchange, and alleviating muscle spasms through its analgesic and circulatory effects.

Question 5

What is the primary contraindication for using electrotherapy?

Accepted Answer

Individuals with pacemakers or heart issues.

Answer

Individuals with pacemakers or other implanted electronic devices are a primary contraindication for electrotherapy. The electrical currents from the therapy can interfere with the function of these devices, potentially leading to serious cardiac complications or device malfunction. Safety precautions must always prioritize patient well-being.
