Kinesiology Unit 1 Exam

Fundamental Position

Similar to anatomic position but the palms are facing medially

Osteokinematics

Joint actions or motion of bones such has hip flexion or elbow extension

Arthrokinematics

Smaller movements between joint such as rolling, sliding, spinning.

How does a convex joint surface move?

The joint surface moves in the opposite direction of the bone.

How does a concave joint surface move?

The joint surface moves in the same direction of the bone.

What are some primary factors that affect joint ROM?

Bone shape, injury, age, occupation, & swelling

What does it mean when a joint is in open packed or loose-packed position?

Ligaments and joint capsules are on slack and there is minimal joint surface contact. Joint mobility is at its greatest in this position.

What does it mean when a joint is in closed packed?

Max tightness or ligaments and joint capsule. Maximal joint surface contact.

Open Chain Exercise

The distal segment moves, and the proximal segment is fixed.

Closed Chain Exercise

The distal segment is fixed to the earth and the proximal segment moves.
