Manual Muscle Testing Quiz

Excess application of resistance can lead to possible muscle fiber tears. This is because when the muscles are subjected to excessive force or load, they may not be able to withstand it, resulting in tears or damage to the muscle fibers. This can happen during activities like weightlifting or intense workouts where the muscles are pushed beyond their limits. Therefore, it is important to exercise caution and gradually increase resistance to avoid such injuries.

The statement is true because MMT, which stands for Manual Muscle Testing, is a technique used to assess muscle strength and function without the need for any equipment. This makes it a convenient and accessible method that can be performed anywhere, without the need for specialized tools or machinery. By relying solely on the examiner's hands and the individual's muscle response, MMT allows for a cost-effective and portable way to evaluate muscle strength and monitor progress in rehabilitation or fitness programs.

Manual muscle testing involves applying resistance to the voluntary maximum contraction of the patient's muscle. The tester applies resistance, which is the force opposing the muscle's movement. The force of gravity is not directly involved in manual muscle testing. The term "contraction" refers to the muscle's action of shortening and generating force.

MMT stands for Manual Muscle Testing, which is a method used to evaluate the strength and function of individual muscles or muscle groups. This technique requires the client to actively contract their muscles voluntarily. Therefore, it is appropriate for clients who are able to voluntarily contract their muscles. The statement "MMT is appropriate for clients who are able to VOLUNTARILY contract muscles" is true.

Group muscle testing refers to the evaluation of muscle strength and function in a group of muscles rather than individual muscles. It allows for a comprehensive assessment of muscle performance throughout the entire range of motion (ROM) of a joint or muscle group. This method is beneficial as it provides a more accurate representation of overall muscle function and identifies any weaknesses or imbalances that may exist. Therefore, the statement that group muscle testing has increased functionality and assessment occurs throughout the entire ROM is true.

The statement suggests that individual muscles may not be isolated and tested separately. However, this statement is false. In many cases, individual muscles can be isolated and tested separately to assess their strength, function, or any abnormalities. This is commonly done in medical examinations, physical therapy, or sports performance evaluations where specific muscles need to be assessed for their strength or weakness.

When testing resistance on two-joint muscles, applying maximum resistance at or near midrange is the best approach. This is because midrange is the position where the muscle is at its optimal length-tension relationship, allowing for maximum force production. Applying resistance at this point ensures that the muscle is challenged to its fullest capacity and provides a more accurate assessment of its strength and function.

A muscle that demonstrates contractility would be graded as Trace (T) or 1/5 because a trace grade indicates that there is minimal muscle contraction or flicker of movement present, but it is not strong enough to cause any joint movement. This suggests that the muscle has some ability to contract, but it is very weak.

When testing resistance on one-joint muscles, it is best to apply the external force at the end of the range. This is because the end of the range represents the maximum lengthening or shortening of the muscle, allowing for a more accurate assessment of its strength and resistance. Applying the force at this point ensures that the muscle is being challenged to its fullest capacity, providing a more reliable measurement of its capabilities.

The term "break test" refers to a testing technique where the muscle is subjected to an isometric contraction at the end range of motion. This test is used to assess the strength and stability of the muscle. The other options provided, such as "resistance check," "contractability test," and "make test," do not accurately describe the specific testing method mentioned in the question.

Functional strength testing may be performed by observation of a person engaging in daily life activities.

The statement suggests that the resistance application of manual resistance is a concrete variable. However, the correct answer is false. This means that the resistance application of manual resistance is not a concrete variable. The term "concrete variable" typically refers to a measurable or observable factor that can be directly observed or manipulated. In this case, the resistance application of manual resistance may involve subjective factors such as the force applied by the person providing the resistance, making it less concrete and more subjective.

Again, because it is subjective, resistance MMT has poor reliability and validity above the fair or 3/5 grade,

The given answer, "Reliability of the MMT," is the correct explanation for the provided information. The factors mentioned, such as client cooperation, tester experience, and environmental conditions, all contribute to the reliability of the Manual Muscle Testing (MMT) results. Reliability refers to the consistency and accuracy of the measurements obtained through the MMT. Therefore, ensuring that these factors are optimized will increase the reliability of the MMT and the validity of the patient's results.

The correct answer is False. The reason is that an MMT (Manual Muscle Test) is not used to assess contractability or muscle tone. It is used to assess the strength of individual muscles by manually applying resistance to the muscle while the person performs specific movements. To assess contractability or muscle tone, other assessment techniques such as passive range of motion or observation of muscle response to stimulation would be more appropriate.

Palpation is best performed using the middle finger because it provides a more precise and sensitive touch compared to the thumbs or index finger. The middle finger is able to detect subtle changes in the muscle texture, tension, and any abnormalities more effectively. Additionally, using the middle finger allows for better control and accuracy in locating specific points of tenderness or muscle tightness during palpation.

Option 1) B is the correct answer because it accurately describes the use and purpose of an isokinetic dynamometer. It states that it assesses limb muscle groups and measures various factors such as peak and average force, reaction time, rate of motor recruitment, and maximum voluntary exertion and fatigue. This aligns with the characteristics and capabilities of an isokinetic dynamometer. Option 2) A is also correct as it describes the use of an isometric dynamometer, which involves constant weight or resistance with muscle contraction at accommodating speed and resistance. Option 3) C is correct as well, as it explains the use of an isotonic dynamometer, which measures strength as the joint moves at a constant preselected speed with resistance applied throughout the range of motion.

The given correct answer, "make test," refers to a testing method where the muscle is tested by applying resistance in the direction opposite to its rotary component. This causes the muscle to perform a concentric type of contraction. The term "make" in this context refers to the muscle's ability to generate force against the resistance. Therefore, the make test is used to assess the muscle's strength and contractile capabilities.
