Questions

Question 1

D i f f e r e n ebetween ‘biomechanics’ B “kinematics

Answer 1

Biomechanics:

Study of mechanical aspects in living organisms.
Analyzes forces on biological structures for understanding movement.
Applied in sports science, rehabilitation, and ergonomics.
Kinematics:

Branch of mechanics focusing on motion analysis.
Describes displacement, velocity, and acceleration.
Doesn’t consider forces causing motion.

Question 2

Diflerence between
“hypetonicing’ “hypertonicity’

Answer 2

increases muscle tone
decrease muscle tone

Question 3

Describe the difference between 1st and 3rd class ievers.

Answer 3

1st Class Lever:

Fulcrum is positioned between the effort force and the load.
Examples include a seesaw and scissors.

3rd Class Lever:

Load is positioned between the fulcrum and the effort force.
Examples include a broom and human forearm during flexion.

Question 4

D e s c r i b e the difference between Tenodesis release è Tenodesis grasp.

Question 5

What is meant by hypererextension and cause?

Answer 5

Hyperextension refers to the excessive extension or straightening of a joint beyond its normal anatomical position.
It often puts stress on the joint and its supporting structures.
Cause:

Causes of hyperextension can include trauma, accidents, or forceful movements that push a joint beyond its usual range.
Sporting injuries, falls, or accidents are common scenarios leading to hyperextension.
Weakness in supporting muscles or ligaments may contribute to increased vulnerability to hyperextension injuries.

Question 6

Whatistheleast efficient lever system? Why?

Answer 6

The least efficient lever system is the 3rd class lever. In a 3rd class lever, the effort force is applied between the fulcrum and the load. This arrangement provides a mechanical disadvantage because the effort arm (distance from the fulcrum to the point of force application) is shorter than the load arm (distance from the fulcrum to the point of the load).

Question 7

What is the most efficient lever system

Answer 7

The 2nd class lever system is considered the most mechanically efficient among the three types of levers.

The load arm (distance from the fulcrum to the load) is longer than the effort arm (distance from the fulcrum to the point of force application).

Question 8

Describe bowstringing, what prevents it?

Answer 8

Bowstringing refers to a situation where a tendon or a muscle moves out of its normal position, creating a bowstring-like appearance.

Proper muscle balance and strength help stabilize joints and maintain the correct tension on tendons, reducing the likelihood of displacement.

Question 9

What Causes
C a r p a l Tunnel syndrome?

Answer 9

Carpal Tunnel Syndrome is caused by compression or irritation of the median nerve as it passes through the carpal tunnel, a narrow passageway in the wrist.

Trauma or Injury:
Wrist injuries or trauma, such as fractures or dislocations, can cause swelling and pressure on the median nerve, leading to CTS.

Question 10

A common elbow joint injury is

Answer 10

A common elbow joint injury is Tennis Elbow, also known as lateral epicondylitis. Tennis Elbow is an overuse injury that typically results from repetitive motion and strain on the forearm muscles and tendons
