1

Joint integrity

describing if the joint is anatomically and biomechanically normal

Considers more than just mobility

2

Joint mobility

the ability of the joint to be moved passively

3

Accessory motion/joint play

small, isolated motions normally present at a joint that must be performed passively by an examiner or external force

can’t be done actively

4

Force production issues (AROM is less than PROM)

nerve recruitment (PNS/CNS)

low muscle mass

muscle is tethered or inferior

lack of motivation

5

Reduced PROM can be due to

Shortened internal joint structures (ligaments and joint capsules)

Fat tissue adhered to structures around joint

Muscles are too tight

Patient is afraid or in pain

6

Assessment of joint play considers what

anatomical issues causing reduced ROM and also overstretching injuries

7

Sprain

overstretched ligaments and capsules

8

Strain

overstretched muscles and tendons

9

Grades of sprains

Grade 1: overstretching, majority of fibers intact
Generally pain, normal motion, normal end feel

Grade 2: partial tear
Generally pain, slightly abnormal, softer end feel

Grade 3: complete tear
Generally no pain, abnormal amount of motion, soft end feel

10

Swelling

general term for extra fluid in an area

11

Edema

fluid between tissue layers; joint was violated and fluid got out or something else going on

12

Effusion

fluid encapsulated within the joint, usually needs a needle to remove the fluid

13

Hypermobile

more than normal mobility

14

Hypomobile

less than normal mobility

15

Generally expect more mobility from

women and younger age groups

16

Laxity vs Instability

Laxity - more motion than normal, loose motion, CT longer than normal

Instability - symptomatic manifestation

17

End feel

the sensation the PT can feel at the end of ROM

18

Types of End Feel (PT terms)

Tissue approximation
Capsular end feel
Bony end feel
Spasm end feel
Empty end feel

19

End Feel - Tissue approximation

subcutaneous tissues pushing against each other and limiting ROM

EX: elbow flexion

20

End Feel - Capsular

joint capsule is limiting the ROM

Feels like stretching a leather belt

EX: shoulder lateral rotation

21

End Feel - Bony

bone touching bone is limiting the ROM

hard, clear stop

EX: elbow extension

22

End Feel - Spasm

muscles abruptly halt motion due to intense pain and guarding

23

End Feel - Empty

patient may be in pain but nothing physically stops you from going farther into ROM
