Ultrasound Quizzes & Trivia

In Physiotherapy, physical therapists are taught about the therapeutic implementation of several physical agents that are called modalities. Generally, these agents are thermal, electrical, sound, light and mechanical. This quiz has been developed to test your knowledge of Physical agent modalities, also known as P. A. Ms. So, let's try out the quiz. Good luck!

    Physiological responses to heat: true or false and if false pick the correct statement. "Heat assists with pain relief and reduces muscle spasms.the precise mechanism is fully understood and appears to be related to the ability of heat to alter nerve ending, decrease the pain threshold and change the firing rates of muscle spasms
    • A. 

      True

    • B. 

      False...The correct statement is: "Heat assists with pain relief and reduces muscle spasms.the precise mechanism is not fully understood and appears to be related to the ability of heat to alter nerve conduction velocity, Increase the pain threshold and change the firing rates of muscle spindles.
