Capsular Pattern |
Inflammation of the joint capsule
When inflammation of a joint is present (known as synovitis or capsulitis), not only does passive stretching of the capsule cause pain but a limitation of range of motion of the involved joint is always found to be in a specific pattern (different for each joint) |

|
MMT grades |
5 - Normal - Holds against max
4 - Good - Breaks with max 3 - Fair - Breaks with mod 2 - Poor - Gravity Eliminated 1 - Trace - No motion, muscles contract 0 - None |
|
|
Law of acceleration |
The amount of acceleration depends on the strength of the force applied to an object
|
|
|
Periosteum Definition |
The thin fibrous membrane that covers all of the bone except the articular surfaces that are covered with hyaline cartilage
|
|
|
Endosteum Definition |
A membrane that lines the medullary canal - contains osteoclasts which are mainly responsible for bone resorption.

|
|
End Feels |
Subjective assessment of the quality of the fell when slight pressure is applied at the end of a joint's PROM.
Bony, Soft Tissue Stretch, Soft Tissue Aproximation, Abnormal Bony, Boggy, Empty, Muscle Spasm, Springy Block, etc. |
