The definition of a Normal Hard End feel is:
- A.
Full ROM at a joint where soft tissue stops the motion
- B.
Full ROM at the joint where a boney structure stops the motion
- C.
Full ROM at the joint where tendons stop the motion
- D.
Full ROM at the joint where cartilage stops the motion
Correct Answer
B. Full ROM at the joint where a boney structure stops the motionExplanation
A Normal Hard End feel refers to the feeling of a hard stop or barrier at the end of the joint's range of motion (ROM) caused by a bony structure. This means that when the joint is moved to its maximum extent, it encounters a solid, unyielding blockage due to the contact between two bones. This can be felt as a hard and abrupt halt in movement, indicating the normal anatomical limitation of the joint's motion.Rate this question:

The definition of a Normal Firm End feel is:
- A.
Full ROM at a joint where soft tissue stops the motion
- B.
Full ROM at the joint where a boney structure stops the motion
- C.
Full ROM at the joint where tendons stop the motion
- D.
Full ROM at the joint where cartilage stops the motion
Correct Answer
C. Full ROM at the joint where tendons stop the motionExplanation
A normal firm end feel occurs when there is full range of motion (ROM) at a joint, but the motion is stopped by the tension in the tendons surrounding the joint. This means that the tendons are providing resistance and preventing further movement, giving a firm sensation when the end of the ROM is reached. This type of end feel is commonly found in joints such as the elbow or knee, where the tendons play a significant role in stabilizing the joint and limiting excessive motion.Rate this question:

The definition of a Normal Soft End feel is:
- A.
Full ROM at a joint where soft tissue stops the motion
- B.
Full ROM at the joint where a boney structure stops the motion
- C.
Full ROM at the joint where tendons stop the motion
- D.
Full ROM at the joint where cartilage stops the motion
Correct Answer
A. Full ROM at a joint where soft tissue stops the motionExplanation
A normal soft end feel refers to a situation where there is full range of motion (ROM) at a joint, but the motion is stopped by the presence of soft tissue. This means that the joint can move freely until it reaches a point where the soft tissue, such as muscles or ligaments, restrict further movement. This is a normal and expected end feel for many joints in the body.Rate this question:

An example of an Abnormal End feel that is SOFT is:
- A.
Decreased ROM at a joint where cartilage stops the motion
- B.
Decreased ROM at a joint where joint edema stops the motion
- C.
Decreased ROM at a joint where pain stops the motion
- D.
Decreased ROM at a joint where a ligament stops the motion
Correct Answer
B. Decreased ROM at a joint where joint edema stops the motionExplanation
An abnormal end feel refers to the sensation felt when a joint reaches its end range of motion. A soft end feel typically occurs when there is swelling or edema in the joint, which restricts further movement. In this case, the decreased range of motion at a joint where joint edema stops the motion would result in a soft end feel.Rate this question:

An example of an Abnormal End feel that is EMPTY is:
- A.
Decreased ROM at a joint where cartilage stops the motion
- B.
Decreased ROM at a joint where joint edema stops the motion
- C.
Decreased ROM at a joint where pain stops the motion
- D.
Decreased ROM at a joint where a ligament stops the motion
Correct Answer
C. Decreased ROM at a joint where pain stops the motionExplanation
When there is a decreased range of motion (ROM) at a joint and the motion is stopped due to pain, it is considered an example of an abnormal end feel that is empty. In this case, the joint does not reach its full range of motion due to pain, rather than any physical obstruction or limitation.Rate this question:

Which of the following is a situation in which the therapist should proceed with caution when measuring ROM?
- A.
No limitations with occupational performance
- B.
Unhealed fracture
- C.
Joint dislocation
- D.
Inflammatory process in joint
Correct Answer
D. Inflammatory process in jointExplanation
When measuring range of motion (ROM), it is important for the therapist to proceed with caution in the presence of an inflammatory process in the joint. Inflammation can cause pain, swelling, and stiffness, which can affect the accuracy and reliability of ROM measurements. It is crucial to be mindful of the patient's comfort and avoid exacerbating the inflammation during the assessment.Rate this question:

Which of the following situation is a contraindication for performing a ROM assessment?
- A.
Patients on a pain medication
- B.
Presence of a hematoma
- C.
Presence of a joint inflammation
- D.
Presence of heterotrophic ossification
Correct Answer
D. Presence of heterotrophic ossificationExplanation
Heterotrophic ossification refers to the abnormal formation of bone in soft tissues such as muscles, tendons, or ligaments. It can restrict joint movement and cause pain. Therefore, the presence of heterotrophic ossification is a contraindication for performing a range of motion (ROM) assessment as it may cause further damage or discomfort to the patient.Rate this question:

Which statement is correct about ROM and MMT assessment?
- A.
MMT should be assessed before ROM to determine muscle strength in order to understand joint integrity
- B.
MMT should be assessed before ROM to determine how much mobility is available in the joint in order to understand muscle strength
- C.
ROM should be assessed before MMT to determine muscle strength and muscle contraction in order to understand joint function
- D.
ROM should be assessed before MMT to determine the amount of joint mobility and joint integrity in order to understand muscle strength
Correct Answer
D. ROM should be assessed before MMT to determine the amount of joint mobility and joint integrity in order to understand muscle strengthExplanation
ROM (Range of Motion) assessment involves measuring the amount of movement that a joint can achieve. By assessing ROM first, we can determine the extent of joint mobility and integrity. This information is crucial in understanding muscle strength because it helps us identify any limitations or restrictions in joint movement that may affect muscle function. MMT (Manual Muscle Testing) assessment, on the other hand, evaluates the strength of specific muscles. Therefore, assessing ROM before MMT allows us to have a comprehensive understanding of both joint mobility/integrity and muscle strength, which are interconnected.Rate this question:

Which of the following statements is NOT true about the differences between AROM and PROM:
- A.
AROM is always larger than PROM because of muscle contraction
- B.
A decrease in PROM and AROM of a joint may be due to joint contracture
- C.
If PROM is WNL but AROM is limited, muscle strength may be the limiting factor
- D.
PROM is equal to or larger than AROM because of stretch of soft tissues and relaxed muscles
Correct Answer
A. AROM is always larger than PROM because of muscle contractionExplanation
The statement that AROM is always larger than PROM because of muscle contraction is not true. AROM (Active Range of Motion) refers to the range of motion that a person can achieve on their own, while PROM (Passive Range of Motion) refers to the range of motion that can be achieved with the help of an external force. In some cases, such as when there is muscle weakness or injury, AROM may be limited and smaller than PROM. Therefore, the statement is incorrect.Rate this question:

- A.
Pt. has -105 degrees of elbow flexion
- B.
Pt. has -30 degrees of elbow extension
- C.
Pt. can fully flex elbow
- D.
Pt. can fully extend elbow
Correct Answer
B. Pt. has -30 degrees of elbow extensionExplanation
The correct answer is "Pt. has -30 degrees of elbow extension." This means that the patient is able to extend their elbow up to 30 degrees beyond the neutral position. The negative sign indicates that the extension is limited or restricted.Rate this question:

Two situations in which completion of MMT assessment is contraindicated are:
- A.
Patient is on pain medication and is fatigued
- B.
Patient has joint pain and inflammation
- C.
Patient has hypertension and diabetes
- D.
Patient has joint hypermobility and COPD
Correct Answer
B. Patient has joint pain and inflammationExplanation
The completion of MMT assessment is contraindicated in patients who have joint pain and inflammation. This is because performing the assessment may exacerbate their pain and inflammation, potentially causing further harm or discomfort. It is important to prioritize the patient's comfort and well-being in such cases and consider alternative assessment methods or wait until the pain and inflammation subside before conducting the MMT assessment.Rate this question:

You are doing ROM and MMT assessment of shoulder flexion of a patient. The patient demonstrates full PROM of shoulder flexion. However, during AROM against gravity, patient can only flex shoulder from 0-100 degrees. Which of the following interpretation is correct:
- A.
You should retest AROM of shoulder flexion using moderated resistance
- B.
Patient has mechanical shoulder joint issues
- C.
You can give the patient a MMT grade of 3- for shoulder flexion
- D.
You can give the patient a muscle grade of 3 for shoulder flexion
Correct Answer
D. You can give the patient a muscle grade of 3 for shoulder flexionExplanation
The patient's ability to perform full passive range of motion (PROM) indicates that there are no restrictions or limitations in the shoulder joint itself. However, the patient's limited active range of motion (AROM) against gravity suggests that there may be a muscle weakness or dysfunction. Therefore, giving the patient a muscle grade of 3 for shoulder flexion is the correct interpretation.Rate this question:

Functions of the elbow complex include all of the following EXCEPT:
- A.
The rotation at the elbow complex allows for orientation of the hand during activities
- B.
The elbow provides stability during UE weight-bearing activities
- C.
Muscle movement of the elbow is functionally independent from movement of the shoulder or wrist
- D.
The elbow provides mobility of the hand in space by lengthening and shortening the UE
Correct Answer
C. Muscle movement of the elbow is functionally independent from movement of the shoulder or wristExplanation
The correct answer is that muscle movement of the elbow is functionally independent from movement of the shoulder or wrist. This means that the muscles responsible for moving the elbow do not rely on or affect the movement of the shoulder or wrist. The other statements explain the functions of the elbow complex, such as allowing for hand orientation, providing stability during weight-bearing activities, and providing mobility of the hand in space.Rate this question:

Minimal length of the Biceps occurs in which of the following joint positions:
- A.
Full shoulder extension, full elbow flexion, full forearm pronation
- B.
Full shoulder flexion, full elbow flexion, full forearm supination
- C.
Full shoulder flexion, full elbow extension, full forearm supination
- D.
Full shoulder extension, full elbow extension, full forearm pronation
Correct Answer
B. Full shoulder flexion, full elbow flexion, full forearm supinationExplanation
During full shoulder flexion, full elbow flexion, and full forearm supination, the biceps muscle is in its most shortened position, resulting in minimal length. This is because the biceps muscle is responsible for flexing the elbow and supinating the forearm. When the shoulder is flexed, the elbow is flexed, and the forearm is supinated, the biceps muscle is maximally contracted, leading to minimal length.Rate this question:

When applying resistance during a MMT, should you place your hand proximal or distal the joint of the muscle being tested? WHY?
- A.
Your hand needs to be placed on the distal end of the bone that is being moved by the muscle bc you have better mechanical advantage
- B.
Your hand needs to be placed on the proximal end of the bone that is being moved by the muscle bc you can eliminate muscle subsitutions
- C.
Your hand needs to be placed on the proximal end of the bone that is being moved by the muscle bc you have better mechanical advantage
- D.
Your hand needs to be placed on the distal end of the bone that is being moved by the muscle bc you will be able to palpate the muscle
Correct Answer
A. Your hand needs to be placed on the distal end of the bone that is being moved by the muscle bc you have better mechanical advantageExplanation
Placing the hand on the distal end of the bone that is being moved by the muscle provides better mechanical advantage during a manual muscle test. This is because the lever arm is longer, allowing for more leverage and easier application of resistance. By placing the hand distal to the joint, the tester can effectively resist the muscle's action while minimizing the involvement of other muscles and reducing the risk of muscle substitutions.Rate this question:

Should MMT be performed with the joint in closed packed position or an open packed position? WHY?
- A.
MMT should be performed with the joint in open packed position so that the client can stabilize joint using joint soft tissue and/or boney structures
- B.
MMT should be performed with the joint in closed packed position so that the client can stabilize the joint using joint soft tissue and/or boney structures
- C.
MMT should be performed wit the joint in open packed position so that the client uses muscles and not joint soft tissue and/or boney structures to stabilize the joint
- D.
MMT should be performed with the joint in closed packed position so that the client uses muscles and not joint soft tissues and/or boney structures to stabilize the joint
Correct Answer
C. MMT should be performed wit the joint in open packed position so that the client uses muscles and not joint soft tissue and/or boney structures to stabilize the jointExplanation
The correct answer is that MMT should be performed with the joint in an open packed position so that the client uses muscles and not joint soft tissue and/or boney structures to stabilize the joint. This is because when the joint is in an open packed position, the muscles surrounding the joint are more actively engaged and can provide better stability. In contrast, when the joint is in a closed packed position, the joint surfaces are maximally congruent and the surrounding soft tissues are under more tension, making it more difficult to isolate and assess the specific muscle strength.Rate this question:

Minimum length of the pronator teres occurs in which of the following joint positions:
- A.
Full elbow extension, full forearm supination, position of shoulder is inconsequential
- B.
Full elbow flexion, full forearm pronation, positon of shoulder is inconsequential
- C.
Full elbow flexion, full forearm supination, full shoulder flexion
- D.
Full elbow extension, full forearm pronation, full shoulder extension
Correct Answer
B. Full elbow flexion, full forearm pronation, positon of shoulder is inconsequentialExplanation
The pronator teres is a muscle located in the forearm that plays a role in pronating the forearm (rotating it so that the palm faces downwards). The minimum length of the pronator teres occurs when the forearm is fully pronated (rotated inwards) and the elbow is fully flexed (bent). The position of the shoulder is inconsequential because the pronator teres only acts on the forearm and not the shoulder joint.Rate this question:

All of the following functions of the brachioradialis muscle are correct EXCEPT:
- A.
The brachioradialis muscle can function as an elbow joint stabilizer
- B.
The angle of pull of the brachioradialis muscle allows for joint approximation
- C.
The brachioradialis muscle operates as a force in a third-class lever system
- D.
The brachioradialis muscle operates as a force in a second-class lever system
Correct Answer
C. The brachioradialis muscle operates as a force in a third-class lever systemExplanation
The brachioradialis muscle operates as a force in a second-class lever system. In a second-class lever system, the resistance is located between the force and the fulcrum. The brachioradialis muscle acts as the force, the elbow joint acts as the fulcrum, and the weight of the forearm acts as the resistance. This lever system allows for greater force production but at the expense of speed and range of motion. However, the brachioradialis muscle does not operate as a force in a third-class lever system, where the force is located between the fulcrum and the resistance.Rate this question:

If slow supination is occuring without resistance (example: positioning your hand in a palms up position to recieve change from the cashier), which muscle of the forarm is most active?
- A.
Brachioradialis
- B.
Biceps
- C.
Brachialis
- D.
Supinator
Correct Answer
D. SupinatorExplanation
When slow supination occurs without resistance, the muscle that is most active is the Supinator. The Supinator muscle is responsible for turning the palm of the hand upward. In this scenario, when positioning the hand in a palms up position to receive change from the cashier, the Supinator muscle is primarily engaged in the movement of supination. The other muscles listed, such as Brachioradialis, Biceps, and Brachialis, may also be involved in the movement to some extent, but the Supinator muscle is the most active in this particular action.Rate this question:

If fast supination is occuring with resistance (example: when using a screw driver to tighten a screw), which additional muscles is recruited for the action of supination?
- A.
Brachioradialis
- B.
Biceps
- C.
Brachialis
- D.
Supinator
Correct Answer
B. BicepsExplanation
When performing fast supination with resistance, the biceps muscle is recruited in addition to the other muscles listed. The biceps muscle is responsible for the flexion of the elbow joint and also assists in the supination of the forearm. Therefore, when there is resistance involved in the supination movement, the biceps muscle is activated to provide the necessary strength and stability to perform the action effectively.Rate this question:

- C.
Inflammtion of the triceps tendon at the olecranon process due to repeated and forceful elbow extension
- D.
Inflammation of the wrist extensors or wrist flexors at their origins (medial epidcondyle for wrist flexors; lateral epicondyle for wrist extensors) due to repeated forceful action of wrist extensors or wrist flexion
Correct Answer
D. Inflammation of the wrist extensors or wrist flexors at their origins (medial epidcondyle for wrist flexors; lateral epicondyle for wrist extensors) due to repeated forceful action of wrist extensors or wrist flexionExplanation
Tennis elbow, also known as lateral epicondylitis, is caused by inflammation of the wrist extensors or wrist flexors at their origins. This inflammation occurs at the lateral epicondyle for wrist extensors and the medial epicondyle for wrist flexors. The repeated and forceful action of wrist extensors or wrist flexion, such as during a tennis swing, can lead to this condition. The inflammation and repetitive stress on these tendons result in pain and discomfort in the outer part of the elbow.Rate this question:

Why is elbow positioning critical for optimal function of the extrinsic muscles of the hand? What is the optimal position of the elbow for extrinsic hand function?
- A.
Because extrensic muscles insert distal to the elbow joint, elbow position can impact the length tension relationship of the extrinsic muscles. Elbow flexion at 100 degrees is optimal position.
- B.
Because extrinsic muscles of the hand do not cross the elbow joint, elbow position is not critical
- C.
Because extrinsic muscles of the hand do not cross the elbow joint, elbow position can impact the length tension relationships of the extrinsic muscles. Elbow flexion at 75 degrees is optimal position.
- D.
Because extrinsic muscles of the hand cross the elbow joint, elbow position can impact length tension relationships of extrinsic muscles. Elbow flexion at 90 degrees is optimal position.
Correct Answer
D. Because extrinsic muscles of the hand cross the elbow joint, elbow position can impact length tension relationships of extrinsic muscles. Elbow flexion at 90 degrees is optimal position.Explanation
Elbow positioning is critical for optimal function of the extrinsic muscles of the hand because these muscles cross the elbow joint. The length tension relationship of the extrinsic muscles can be affected by the position of the elbow. The optimal position for extrinsic hand function is elbow flexion at 90 degrees.Rate this question:

When performing muscle strength testing on the brachialis muscle, how should you position the forearm?
- A.
Forearm should be positioned in supination
- B.
Forearm should be positioned in pronation
- C.
Forearm should be positioned in mid-position
- D.
Forearm position does not matter
Correct Answer
B. Forearm should be positioned in pronationExplanation
When performing muscle strength testing on the brachialis muscle, the forearm should be positioned in pronation. This is because the brachialis muscle is a flexor of the elbow joint and is most active when the forearm is in a pronated position. Pronation refers to the rotation of the forearm so that the palm faces downwards. By positioning the forearm in pronation, the brachialis muscle is placed in an optimal position for contraction and can generate the most force during the strength testing.Rate this question:
