  • 2. 

    Subtle postural shifts will completely change muscle activity.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    Subtle postural shifts can indeed have a significant impact on muscle activity. Even small adjustments in posture can alter the distribution of forces and load on different muscles, leading to changes in muscle activation patterns. This means that even slight changes in body position can result in different muscles being engaged or disengaged. Therefore, it is accurate to say that subtle postural shifts can completely change muscle activity.

    You're sitting in a recliner watching TV. You accidentally drop the remote. You have to lean forward to grab it. In this scenario, your abdominals are working ______________.

    • Eccentrically

    • Concentrically

    • They're not working. I would leave the remote on the floor.

    Correct Answer
    A. Concentrically
    Explanation
    In this scenario, your abdominals are working concentrically. This means that they are contracting and shortening in order to bring your torso forward and allow you to grab the remote.

    Patients who are _________________ will have trouble dissociating their muscle actions.

    • Weak or posturally insecure

    • Freezing their degrees of freedom

    • Spastic

    • All of the above

    Correct Answer
    A. All of the above
    Explanation
    Patients who are weak or posturally insecure, freezing their degrees of freedom, or spastic will have trouble dissociating their muscle actions. This means that they will have difficulty in coordinating and controlling their muscle movements, leading to impaired motor function.

    You're sitting in a neutral position. You turn/rotate your body to the right. The internal obliques on the _____ side of the body are working as well as the external obliques on the ________ side of your body.

    • Right / Left

    • Left / Right

    Correct Answer
    A. Right / Left
    Explanation
    When acting unilaterally, internal obliques turn the vertebral column to the same side. The external obliques, when working unilaterally, turn the vertebral column to the OPPOSITE side.

    The abdominals are most active when:

    • The shoulders are behind the hips

    • The shoulders are in front of the hips

    Correct Answer
    A. The shoulders are behind the hips
    Explanation
    When the shoulders are behind the hips, it creates a posterior pelvic tilt, which activates the abdominal muscles. This position helps to stabilize the spine and maintain proper alignment. The abdominals have to work harder to prevent the hips from tilting forward and to maintain a neutral spine. On the other hand, when the shoulders are in front of the hips, it creates an anterior pelvic tilt, which lengthens and relaxes the abdominal muscles. This position can lead to poor posture and decreased abdominal activation.

    What is the normal range of motion of the cervical portion of the spine?

    • Flexion: 40 / Extension: 75 / Lat. Flex.: 35-45 / Rotation: 45-50

    • Flexion: 105 / Extension: 60 / Lat. Flex.: 20 / Rotation: 35

    • Flexion: ---- / Extension: ----- / Lat. Flex.: 20 / Rotation: 5

    • Flexion: 140 / Extension: 140 / Lat. Flex.: 75-85 / Rotation: 90

    Correct Answer
    A. Flexion: 40 / Extension: 75 / Lat. Flex.: 35-45 / Rotation: 45-50
    Explanation
    The normal range of motion of the cervical portion of the spine includes flexion of 40 degrees, extension of 75 degrees, lateral flexion of 35-45 degrees, and rotation of 45-50 degrees. This means that the neck can bend forward and backward, tilt to the sides, and rotate to some extent within these ranges.

    What is the normal range of motion of the thoracic portion of the spine?

    • Flexion: 40 / Extension: 75 / Lat. Flex.: 35-45 / Rotation: 45-50

    • Flexion: 105 / Extension: 60 / Lat. Flex.: 20 / Rotation: 35

    • Flexion: ---- / Extension: ----- / Lat. Flex.: 20 / Rotation: 5

    • Flexion: 140 / Extension: 140 / Lat. Flex.: 75-85 / Rotation: 90

    Correct Answer
    A. Flexion: 105 / Extension: 60 / Lat. Flex.: 20 / Rotation: 35
    Explanation
    The normal range of motion of the thoracic portion of the spine includes flexion of 105 degrees, extension of 60 degrees, lateral flexion of 20 degrees, and rotation of 35 degrees.

    What is the normal range of motion of the total spine?

    • Flexion: 40 / Extension: 75 / Lat. Flex.: 35-45 / Rotation: 45-50

    • Flexion: 105 / Extension: 60 / Lat. Flex.: 20 / Rotation: 35

    • Flexion: ---- / Extension: ----- / Lat. Flex.: 20 / Rotation: 5

    • Flexion: 140 / Extension: 140 / Lat. Flex.: 75-85 / Rotation: 90

    Correct Answer
    A. Flexion: 140 / Extension: 140 / Lat. Flex.: 75-85 / Rotation: 90
    Explanation
    The normal range of motion of the total spine includes flexion, extension, lateral flexion, and rotation. Flexion refers to the forward bending of the spine, while extension refers to the backward bending. Lateral flexion refers to the side bending of the spine, and rotation refers to the twisting movement. The correct answer states that the normal range of motion for flexion is 140 degrees, for extension is 140 degrees, for lateral flexion is 75-85 degrees, and for rotation is 90 degrees.

    What is the normal range of motion of the lumbar portion of the spine?

    • Flexion: 40 / Extension: 75 / Lat. Flex.: 35-45 / Rotation: 45-50

    • Flexion: 105 / Extension: 60 / Lat. Flex.: 20 / Rotation: 35

    • Flexion: ---- / Extension: ----- / Lat. Flex.: 20 / Rotation: 5

    • Flexion: 140 / Extension: 140 / Lat. Flex.: 75-85 / Rotation: 90

    Correct Answer
    A. Flexion: ---- / Extension: ----- / Lat. Flex.: 20 / Rotation: 5

    The purpose of the abdominal wall and lateral trunk is to: (check all that apply)

    • Support viscera

    • Respiratory assist

    • Trunk control (lateral flexion, rotation, posterior movement - leaning back)

    • Balance of vertebral column

    • Pull pelvis into anterior tilt

    • Accentuate lumbar lordosis

    Correct Answer(s)
    A. Support viscera
    A. Respiratory assist
    A. Trunk control (lateral flexion, rotation, posterior movement - leaning back)
    Explanation
    The purpose of the abdominal wall and lateral trunk is to support the viscera, assist in respiration, and provide trunk control, including lateral flexion, rotation, and posterior movement (leaning back). These functions help maintain the balance of the vertebral column and pull the pelvis into an anterior tilt. Additionally, they accentuate lumbar lordosis, contributing to the overall stability and mobility of the trunk.
