Isometric

The lines that make the width and depth of an isometric drawings are drawn at _______ degrees.

• 45

• 30

• 120

• 15

If the Green is the top view and Red is the front, then what view is the Blue?

• Left Side

• Front

• Back

• Right Side

Isometric contractions performed once the extremity is passively placed into shortened range. Upon relaxation, do quick stretch and pt moves extremity into new range.

• Slow reversals

• Repeated contractions

• Hold-relax active movement

• Joint distraction

Answer explanation

HOLD-RELAX ACTIVE MOVEMENT is good for mobility - it improves the initiation of movement to muscle groups tested at 1/5 or less

Isometric contraction of agonist followed by passive stretch

• Rhythmic initiation

• Contract-relax

• Alternating isometrics

• Hold-relax

Answer explanation

HOLD-RELAX is great for patients who want to improve mobility but have pain

In isometric drawings, which angle is typically used to represent the depth axis?

• 45 degrees

• 60 degrees

• 90 degrees

What is the primary characteristic of an isometric contraction in muscle physiology?

• Muscle length changes

• Muscle tension changes without length change

• Muscle length and tension both change

• No muscle tension

Which of the following is a common use of isometric exercises in rehabilitation?

• Increasing muscle length

• Improving joint flexibility

• Strengthening muscles without joint movement

• Enhancing cardiovascular endurance

In an isometric view, how are the axes typically oriented?

• All axes are at 90 degrees to each other

• Two axes are at 90 degrees, one at 45 degrees

• All axes are at 120 degrees to each other

• Two axes are at 120 degrees, one at 90 degrees

Which of the following best describes an isometric transformation in geometry?

• A transformation that changes the size of a figure

• A transformation that changes the shape of a figure

• A transformation that preserves distances and angles

• A transformation that only changes the orientation of a figure

In isometric projection, which of the following is true about the scale along each axis?

• The scale is different for each axis

• The scale is the same for all axes
