Facilitation of the agonist results in simultaneous inhibition of the antagonist

Reciprocal inhibition
Autogenic inhibition
Irradiation
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.

Used to catch up the lagging part is called timing for emphasis

True
False

Correct Answer

A. True

Explanation

The statement is true. Timing for emphasis refers to the technique of using pauses or delays in speech or performance to highlight or draw attention to a particular part or message. It is commonly used in public speaking, acting, and storytelling to create suspense, build anticipation, or emphasize key points. By strategically timing the delivery of certain words or phrases, speakers can effectively engage their audience and make their message more impactful.

PNF was originally used for polio patients

True
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.

Little "nudges" at the beginning of the motion

Rhythmic stabilization
Rhythmic initiation
Agonist reversal
Slow reversal

Correct Answer

A. Rhythmic initiation

Explanation

Rhythmic initiation refers to the small, gentle movements or "nudges" that are made at the beginning of a motion. These initial movements help to initiate and establish a rhythm or pattern in the motion, allowing for smoother and more controlled movement. It is a technique commonly used in various forms of therapy and rehabilitation to improve coordination, balance, and motor skills. By starting with these rhythmic initiations, individuals can gradually build up to more complex movements and improve their overall motor control and coordination.

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

Autogenic inhibition
Successive induction
Reciprocal inhibition
Irradiation

Correct Answer

A. 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.

Smooth change of direction

Contract relax
Alternating isometrics
Slow reversal
Rhythmic stabilization

Correct Answer

A. 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.

GTO stimulation, to keep from injuring self

Reciprocal inhibition
Successive induction
Autogenic inhibition
Irradiation

Correct Answer

A. 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.

Uses isometric contractions to promote stability using a rotary component

Alternating isometrics
Rhythmic initiation
Repeated contractions
Rhythmic stabilization

Correct Answer

A. Rhythmic stabilization

Explanation

Rhythmic stabilization refers to a technique that uses isometric contractions to promote stability. It involves applying a rotary component to the isometric contractions, which helps to engage and strengthen the muscles involved in stabilizing the body. This technique is often used in rehabilitation and physical therapy settings to improve stability and control in individuals with various musculoskeletal conditions. By incorporating rhythmic stabilization exercises into a treatment plan, the individual can enhance their ability to stabilize their joints and maintain proper alignment during movement.

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

Rhythmic initiation
Repeated contractions
Rhythmic stabilization
Agonist reversal

Correct Answer

A. 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.

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

Irradiation
Successive induction
Autogenic inhibition
Reciprocal inhibition

Correct Answer

A. 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.

isometrics to promote stability using a linear plane direction

Alternating isometrics
Contract relax
Rhythmic stabilization
Agonist reversal

Correct Answer

A. Alternating isometrics

Explanation

Alternating isometrics refers to a technique where muscles are contracted isometrically in a sequential manner, alternating between different muscle groups or directions. This technique is used to promote stability by activating and strengthening the muscles surrounding a joint. By applying isometric contractions in a linear plane direction, the muscles are engaged in a controlled manner, helping to improve stability and control at the joint. This technique is commonly used in rehabilitation settings to enhance joint stability and improve overall function.

Promotes mobility, controlled mobility, and skill by facilitating reversal of a movement

Slow reversal
Agonist reversal
Dynamic reversal

Correct Answer

A. Agonist reversal

Explanation

Agonist reversal refers to a movement that promotes mobility, controlled mobility, and skill by facilitating the reversal of a movement. This means that the muscles that were initially contracting to perform a movement now relax, while the antagonist muscles contract to reverse the movement. Agonist reversal helps improve coordination, flexibility, and overall movement control.
