Q

what do you do for cubital tunnel syndrome rehab?

A
  • nerve gliding exercises
  • help the nerve glide through cubital tunnel at elbow and guyons canal at wrist and prevent stiffness

Q

what is the thoracic outlet

A

  the superior thoracic aperture refers to the superior opening of the thoracic cavity between first rib and collarbone through which brachial plexus (nerve bundle) and subclavian vein and arteries pass.

21
Q

what is thoracic outlet syndrome

A

Thoracic outlet syndrome is a group of disorders that occur when the blood vessels or nerves in the thoracic outlet — the space between your collarbone (clavicle) and your first rib — become compressed

22
Q

when is thoracic outlet syndrome most likely to happen

A

when flexion of arm at shoulder, scapula upward rotated, and ribs elevated

  • also horizontal abduction and internal rotation
  • causes irritation of the brachial plexus
23
Q

what 2 movements of the arm are ‘safe’ for working postures

A
  • 75 degrees across abdomen to 180 degrees above head in frontal plane
  • 60 degrees of extension to 180 degrees of flexion in the sagittal plane
24
Q

what are the 2 types of thoracic outlet syndrome

A
  1. neurological thoracic outlet syndrome

2. vascular thoracic outlet syndrome

25
Q

This form is characterized by compression of the brachial plexus (a network of nerves that come from your spinal cord and control muscle movements and sensation in your shoulder, arm and hand

A

neurological thoracic outlet syndrome

26
Q

This type occurs when one or more of the arteries and veins under the clavicle (subclavian vessels) are compressed.

A

vascular thoracic outlet syndrome

27
Q

what are the neurological signs of thoracic outlet syndrome

A
  1. numbness or tingling in fingers
  2. pain in shoulder or neck
  3. ache in arm or hand
  4. weakening grip
28
Q

what are the vascular signs of thoracic outlet syndrome

A
  1. Discoloration of your hand (bluish color)
  2. Subclavian vein thrombosis 3. Arm pain and swelling
  3. Throbbing lump near your collarbone
  4. Lack of color (pallor) in one or more of your fingers or your entire hand
  5. Tiny black spots (infarcts) on your fingers
29
Q

thrombosis is caused from a ___, it causing pain and swelling and is typically in a ____

A

clot, vein

30
Q

what are 2 thoracic outlet syndrome risk factors

A
  1. Repetitive and forceful Reaching above shoulder level with or without heavy objects (arms above head, decrease blood flow, decrease stroke volume, numbness and weakness)
  2. Prolonged incorrect seated posture
31
Q

what a can we do to decrease risk of thoracic out syndrome

A

strengthening, change position, reduce work load, stretch to create space

32
Q

7 thoracic outlet syndrome rehab exercises

A
  1. scalene stretch
  2. pectoralis stretch
  3. scapular squeeze
  4. arm and side on wall
  5. thoracic extension
  6. rowing exercise
  7. mid trap exercise
33
Q

what is raynaud’s syndrome

A

is when blood vessels of the hand are damaged (narrowed). This results in Abnormal nerve control of the blood-vessel diameter and nerve sensitivity to cold exposure.

34
Q

in raynauds syndrome what is the color change in part related to?

A

initial blood-vessel narrowing due to spasm of the tiny muscles in the wall of the vessels, followed by sudden opening (dilation)

35
Q

2 symptoms of raynauds

A
  1. Numbness and tingling in the fingers

2. Blanching (whitening) of one or more fingertips because of a temporary constriction of blood flow

36
Q

treatment of raynauds

A

is none

  • increasing blood flow to areas does not help too much
  • some ppl respond to vasodilators
37
Q

raynauds occupational risk factors

A

vibrating tools, such as hair clippers and jack hammers

hedge trimmers, chainsaw, hammering

38
Q

6 upper extremity tendon disorders

A
  1. rotator cuff syndrome
  2. tendinitis - irritation of the tendon
  3. ganglion cyst - accumulation of fluid within the tendon sheath
  4. tenosynovitis- irritation of the synovial sheath
  5. dequervains disease - combo of tendinitis and tenosynovitis
  6. trigger finger or thumb- tendon movement problems
39
Q

what is rotator cuff syndrome

A

is a disorder involving swelling and pain of tendons comprising the rotator cuff muscle group: subscapularis, supraspinatus, infraspinatus, & teres minor

40
Q

symptoms of rotator cuff syndrome

A
  1. Pain when you bend the arm and   rotate it outwards against resistance
  2. Pain on the outside of the shoulder possibly radiating down into the arm
  3. Pain in the shoulder, which is worse at night
  4. Stiffness in the shoulder joint.
41
Q

injury to nay muscles of the rotator cuff is considered?

A

rotator cuff syndrome

42
Q

what is the most common cause of tear of rotator cuff

A

external rotation

43
Q

what is normal for external rotation strength

A

10-15lbs (a little more for internal rotation)

44
Q

rehab for rotator cuff syndrome

A

do exercises that strengthen rotator cuff muscles

45
Q

tendinitis=
tendinosis=
both = tendinopathy

A
  • acute response to an injury

- accumulated injuries that don’t want to heal

46
Q

inflammation of a tendon which is caused by the straining, or tearing of the tendon fibers

A

tendonitis

47
Q

chronic injury caused by an accumulation of small tears in the tendon that have failed to heal properly overtime

A

tendinosis

48
Q

tennis elbow =

golfers elbow =

A
  • lateral epicondylitis

- medial epicondylitis

49
Q

4 symptoms of tendinitis

A
  • point tenderness
  • swelling
  • tennis elbow, pain radiates down back oh hand
  • golfers elbow, pain radiates down back of hand
50
Q

a condition that results in deterioration of the tendon fibers that attach to the bone at the outside of the elbow.

A

lateral epicondylitis

51
Q

signs and symptoms of lateral epicondylitis

A

pain occurring where the tendons of the forearm muscle attach to the elbow bone at the lateral epicondyle

52
Q

2 risk factors of lateral epicondilitis

A
  1. repeated use of forearm muscles
  2. chronic stress to the forearm muscles, especially the Extensor Carpi Radialis Brevis. Activities such as meat cutting, hammering, screw driving, plumbing, painting, and weight lifting require steady powerful grasping and gripping movements. using a keyboard places the hand in a raised position for a prolonged length of time.
