Q1Patellar tendonitis is typically found in which of the following sports?
Show answer
✓ Correct answer: All of the above.
Patellar tendonitis, also known as jumper's knee, occurs when the tendon that attaches to the knee cap to the tibia becomes irritated or inflamed. It typically results from repetitive stress placed on the knee during jumping.
Q2After performing a postural analysis on a client, you determine that he has hypertonic rhomboids, trapezius, teres minor, infraspinatus and latissimus dorsi that are causing the shoulder blades to be pulled back, as well as winging the scapula. This condition is called:
Show answer
✓ Correct answer: Retracted shoulders
When in a chronic shortened state, the rhomboids, trapezius, teres minor, infraspinatus and latissimus dorsi will retract the shoulders and wing the scapula.
Q3Jill is a massage therapist and Taylor is her client.<br/><br/>Which of the following describes Jill performing an active range of motion assessment of Taylor?
Show answer
✓ Correct answer: Jill asks Taylor to make arm circles as big as she can.
Active range of motion assessments involve a person moving his or her own body parts and joints.
Q4What is a suitable solution for a massage professional experiencing discomfort in the wrist and elbow area?
Show answer
✓ Correct answer: Relax the hand and fingers during massage.
Improper body mechanics can result in pain. It's important to keep the fingers and wrist relaxed to prevent elbow pain, as the muscle is located in the forearm. All incorrect actions would worsen the pain.
Q5The optimal location to target for accessing the triceps muscle when applying myofascial release techniques is <code>________</code>.
Show answer
✓ Correct answer: Prone
When applying myofascial release techniques to target the triceps muscle, the optimal position is prone. The prone position allows for better access to the triceps muscle and allows the therapist or individual to apply appropriate pressure and techniques to release any tension or tightness in the muscle.
Q6According to the sliding filament theory, when this molecule breaks down, it releases energy that allows Myosin to contract the muscle by pulling the Actin filaments inward, resulting in muscle shortening.
Show answer
✓ Correct answer: ATP
Muscles contract as the myosin heads pull on the actin filaments, shortening the sarcomere. The myosin heads hold both a phosphate and ADP molecule. Initially, the release of the phosphate allows for cross-bridge formation between the myosin heads and the actin binding site.<br/><br/>Subsequently, the release of the ADP molecule enables the myosin heads to pull, initiating a power stroke that shortens the sarcomere. ATP is required to release the cross-bridge and reset the myosin head into a cocked position.
Q7What is the key factor to consider when evaluating the stability of a portable massage table?
Show answer
✓ Correct answer: Cable support
The cable support serves as the structural design component for stability, with the center hinge being the weak point.
Q8When conducting a gait assessment on a client, which of the kinetic measurements listed below is not considered?
Show answer
✓ Correct answer: Pause length.
A massage therapist needs to note four different kinetic measures of the client's gait. They include: the step length, the stride length, the cadence and the velocity. The pause lengths between steps is not an issue, the client can take as much time as necessary to before each motion needed to maintain balance.
Q9When conducting a post-isometric relaxation stretch, the target muscle is extended until a gentle stretch is sensed. At this stage, the target muscle is contracted and then allowed to relax in order to lengthen further. This is an instance of stimulating this proprioceptor:
Show answer
✓ Correct answer: Golgi tendon organ
The golgi tendon organ detects increases in muscle tension to prevent injury. If the muscle tension is significant in relation to the force the muscle can generate, it inhibits the muscle's ability to contract. Engaging this reflex allows for an increased stretch without resistance from the muscle. When stimulated, the muscle spindle contracts the muscle. The Meissner corpuscle detects skin slippage, while the Pacinian corpuscle is responsible for detecting pressure and high vibration frequency in the skin.
Q10The therapist performs a post isometric relaxation stretch on her client. She has her client contract against resistance for <code>________</code> seconds, and stretches the target muscle for <code>________</code> seconds. The stretch is repeated 2 more times and the final stretch time is <code>________</code>.
Show answer
✓ Correct answer: 10, 5, increased
It takes 7 to 10 seconds for the golgi tendon organ to respond to an increase in tension with a relaxation reflex. After the reflex is initiated the muscle is stretched to the new resistance barrier and held to set new muscle memory. The final stretch time is increased to ensure a new muscle length memory is set.
