Fundamentals of PTA Week 2 Lecture

Question 1

Kinetics vs kinematics

Answer 1

Kinetics- Forces and motion only and reveals how forces affect motion.

Kinematics- Motion only–or how an object moves through space–without reference to any associated force.

Question 2

What does SOAP stand for?

Answer 2

Subjective: Things patient/significant other tells us about them
Objective: Tests or measurement
Assessment: Your professional opinion; diagnosis/prognosis; STG/LTG
Plan: Where do I want to go/ how to get there; discharge plans

Question 3

What is osteokinematics?

Answer 3

Movement of bones around a joint axis
- Flexion and extension
- Abduction and adduction
- Lateral and medial rotation

E.g. Humerus moving on the scapula

Question 4

What is arthrokinematics?

Answer 4

Joint surface motion
- Roll, spin, glide.

E.g. Humeral head’s movement within glenoid fossa of scapula

Question 5

Synarthrosis -
Motion?
Structure?
Example?

Answer 5

Has a thin layer of fibrous periosteum between two bones.
Motion - No
Structure - Fibrous-suture joint
Example - Skull

Question 6

Syndesmosis -
Motion?
Structure?
Example?

Answer 6

A fibrous joint that connects two adjacent bones with ligaments or a strong membrane.
Motion - Slight amount of twisting/stretching
Example - Distal tibiofibular joint (in the ankle) and distal radioulnar joint

Question 7

Gomphosis
Motion?
Structure?
Example?

Answer 7

Motion - No
Structure - Fibrous peg in socket
Example - Between teeth and mandible

Question 8

Amphiarthrosis
Motion?
Structure?
Example?

Answer 8

Has either hyaline or fibrocartilage
Motion - Little; bending/twisting; compression; provide stability
Structure - Cartilagenous
Example - Symphysis pubis, vertebrae,

Question 9

Diarthrosis
Motion?
Structure?
Example?

Answer 9

Classified further into movement and degrees of freedom
Motion - Free
Structure - Synovial
Example - Hip, elbow, knee
