1

What is numbness or tingling associated with?

Nerves

2

What is sharp, localized pain associated with?

Tendon

3

What is fatigue associated with?

Muscles

4

What is a clunk, pop, or crack associated with?

5

Explain a thoracic sprain

An exaggeration of the normal curve in the mid back from slouching or looking downward

6

Explain rotator cuff tendonitis

Painful inflammation of tendons in shoulder from pointing elbows outward (chicken wings)

7

Explain thoracic outlet syndrome

Painful symptoms of the forearm, wrist, and/or hand due to compression of the brachial nerve plexus between the neck and shoulder caused from looking downward to one side, hunching shoulders, reaching upward.

8

Explain extensor wad syndrome

Painful disorder of the posterior forearm (at elbow) due to injury to the extensor muscles of the thumb and fingers caused from extending the fingers

9

Explain the pronator syndrome

Painful disorder of the hand caused by compression of the median nerve between the two heads of the pronator teres muscle caused by repetitive grasping, especially with the forearm rotated outward

10

Explain carpal tunnel syndrome

Numbness in the fingers (except pinky) caused from poor posture, bending wrist up/down or side to side, gripping instruments for long periods of time

11

Explain ulnar nerve entrapment

Ulnar nerve is trapped which causes numbness in pinky and ring finger caused by bending wrist up/down and side to side and putting pinky out

12

Explain tendonitis

Pain in wrist and outer edges of hands from repeatedly extending hand up and down at the wrist

13

Explain radial styloid tenosynositis

Pain in the thumb side of the hand palm and base of thumb from forceful pinching or wrist deviation

14

Explain trigger finger

Painful inflammation of the tendons at the base of the individual finger in the palm from repetitive pinching and sustained fist. Finger can get locked in place and sometimes bump at base of finger
