Double Jeopary Qq
What are the benefits of incorporating isometric exercises into a strength training program?
Identify one common deviation in gait.
(just one there are many)
What is a Limp,
a dropping hip,
An unsteady or uneven walking pattern (steppage gait),
Legs cross over each other when walking (scissor gait),
Reduced or incorrect/Uneven arm swing,
forward posture (leading with the head),
flexed hips and knees,
Shuffling, waddling, or prolonged double support phase leading to balance and instability.
Differentiate between a tendon and a ligament.
What is a tendon connects muscle to bone, while a ligament connects bone to bone?
The movement of a limb away from the midline?
What is abduction?
Name a joint that allows for rotation?
What is a pivot joint?
Double Jeopary Qq
What are the differences between pivot joints and ball-and-socket joints in terms of movement?
Which contraction involves both shortening and lengthening of the muscle?
What is an Isotonic Contraction?
Double Jeopardy Qq
Explain the role of the nervous system in initiating and regulating muscle contractions.
Describe what hyperextension of the knee looks like during gait.
What is the knee bending backward during leg movement?
Double Jeopardy Qq?
How can gait analysis help in the rehabilitation of knee injuries?
What is the function of synovial fluid?
What is to lubricate joints and reduce friction?
The Definition of Range of Motion.
What is the term for the maximum extent of movement possible at a joint?
Double Jeopardy Qq:
What role does stretching play in enhancing flexibility and range of motion?
What is the primary stabilizing structure in joints?
What are ligaments?
Double Jeopary Qq
Discuss the role of cartilage in joint function and health.
During a bicep curl, what type of muscle contraction is occurring when the arm is lowering the weight back down?
What is an Eccentric Contraction?
What are the five phases of the gait cycle?
What are initial contact, loading response, mid-stance, terminal stance, and pre-swing?
What are the two main components of intervertebral discs?
What are the nucleus pulposus and annulus fibrosus?
Double Jeopardy Qq
Explain how these structures work together to produce movements of the spine (spinal mechanics)?
A principle explaining how joint surfaces interact during movement.
What is the Convex-Concave Rule
Which joint type is formed between the thumb and the trapezium bone
What is a Saddle Joint
Which type of muscle contraction is commonly used in rehabilitation exercises to improve strength?
What is an Isotonic Contraction?
How does pelvic tilt affect gait?
What is it can cause asymmetrical movement patterns?
+1 for exam
Describe the annulus fibrosus.
What is the tough outer layer of the intervertebral disc?
- It encases the inner nucleus pulposus, helping to distribute loads and allow limited movement between vertebrae while preventing excessive motion. Degeneration of the annulus fibrosus can lead to conditions like herniated discs, which may cause pain and nerve compression.
Which joint in the body is known to have the greatest range of motion?
What is the shoulder joint (glenohumeral joint)?
