Questions and Answers
  • 1. 

    GTO stimulation, to keep from injuring self

    • A.

      Reciprocal inhibition

    • B.

      Successive induction

    • C.

      Autogenic inhibition

    • D.

      Irradiation

    Correct Answer
    C. Autogenic inhibition
    Explanation
    Autogenic inhibition refers to the automatic relaxation of a muscle when it is subjected to a high level of tension. This mechanism is designed to prevent the muscle from injuring itself. When a muscle is stimulated intensely, the Golgi tendon organ (GTO) located within the tendon is activated. The GTO then sends inhibitory signals to the muscle, causing it to relax and reduce tension. This autogenic inhibition helps protect the muscle from potential damage that could occur if it were to contract forcefully for an extended period.

    Energy is channeled from stronger to weaker muscle groups or patterns. Also referred to as "overflow"

    • A.

      Autogenic inhibition

    • B.

      Successive induction

    • C.

      Reciprocal inhibition

    • D.

      Irradiation

    Correct Answer
    D. Irradiation
    Explanation
    Irradiation refers to the concept of energy being channeled from stronger to weaker muscle groups or patterns. It is also known as "overflow." This means that when a stronger muscle group is activated, the energy can spread to weaker muscle groups, causing them to also activate. This phenomenon helps in recruiting more muscle fibers and improving overall muscle coordination and strength.

    An increased response of the agonist results after contraction of its agonist

    • A.

      Irradiation

    • B.

      Successive induction

    • C.

      Autogenic inhibition

    • D.

      Reciprocal inhibition

    Correct Answer
    B. Successive induction
    Explanation
    Successive induction refers to the phenomenon where the activation of one muscle group leads to the activation of another muscle group. In this case, the increased response of the agonist (muscle responsible for the main movement) occurs after the contraction of its agonist (muscle that assists in the movement). This suggests that the contraction of the assisting muscle group enhances the contraction of the main muscle group, resulting in a more powerful movement.

  • 4. 

    Facilitation of the agonist results in simultaneous inhibition of the antagonist

    • A.

      Reciprocal inhibition

    • B.

      Autogenic inhibition

    • C.

      Irradiation

    • D.

      Successive induction

    Correct Answer
    A. Reciprocal inhibition
    Explanation
    Reciprocal inhibition refers to the phenomenon where the facilitation of the agonist muscle leads to the simultaneous inhibition of the antagonist muscle. This occurs due to the activation of inhibitory interneurons in the spinal cord, which prevent the antagonist muscle from contracting while the agonist muscle is active. This reciprocal inhibition helps in coordinating movement and preventing unwanted muscle contractions.

    PNF was originally used for polio patients

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    PNF, which stands for Proprioceptive Neuromuscular Facilitation, was indeed originally used for polio patients. Polio is a viral infection that can cause paralysis, and PNF was developed as a rehabilitation technique to help restore movement and function in affected individuals. By incorporating various movement patterns and muscle contractions, PNF aims to improve muscle strength, flexibility, and coordination. Over time, PNF has been widely adopted in various healthcare settings to treat a range of conditions beyond polio, including stroke, spinal cord injuries, and orthopedic conditions.

    A quick stretch works because it facilitates the muscle spindle causing the muscle to contract.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    A quick stretch works because it stimulates the muscle spindle, which is a sensory receptor located within the muscle. When the muscle spindle is activated, it sends signals to the spinal cord and brain, triggering a reflex contraction of the muscle. This reflex contraction helps to protect the muscle from potential damage and also aids in improving muscle performance and flexibility. Therefore, the statement that a quick stretch works by facilitating the muscle spindle causing the muscle to contract is true.

    Emphasizing movement on one side of the joint to promote strengthening of specific muscles

    • A.

      Rhythmic initiation

    • B.

      Repeated contractions

    • C.

      Rhythmic stabilization

    • D.

      Agonist reversal

    Correct Answer
    B. Repeated contractions
    Explanation
    Repeated contractions involve performing a series of contractions and relaxations of a specific muscle or group of muscles. This repetitive movement helps to strengthen and build endurance in those muscles. By repeatedly contracting the muscles, it promotes muscle growth and improves muscle tone. This type of exercise is often used in strength training and rehabilitation programs to target specific muscles and improve their strength and function.

    Correct Answer
    C. Slow reversal
    Explanation
    Slow reversal refers to a technique in physical therapy where the patient moves a joint or muscle group through a range of motion in one direction, then slowly reverses the movement back to the starting position. This technique helps to improve muscle control, coordination, and joint stability. It also promotes a smooth change of direction during movement, which can be beneficial for patients recovering from injuries or trying to improve their overall strength and mobility.
