25
What are general signs of carpal tunnel with Resisted / MMT?
Weakening grip, pinch, and tip strength, primarily 1st and 2nd digits
26
What are general signs of carpal tunnel with neurological testing?
- Diminished sensation with fast progression to numbness over volar surface of the 1st 3 and a half digits and dorsal tips - DTRs and Myotomes WNL - ULTT for median nerve (conflicting support)
27
What are general signs of carpal tunnel with Accessory Motion Testing?
Possible hypo- or hyper mobility with carpal, RC, or distal RU joints
28
What are carpal tunnel special tests?
- Carpal tunnel compression (inconsistent) - Wainner's CPR (best to rule in) - Two-point discrimination - Tinel's (inconsistent) - Wrist Ratio Index - Decreased sensation on involved fingers - Phalen's (inconsistent) - Reverse Phalen's
29
What is the PT rx for carpal tunnel syndrome?
- POLI (no c) ED - bc compression is most often the cause - pt education - Modalities
30
What is the patient education for CTS?
Pathology and risk factors Aggravating factors
31
What should we know about modalities for CTS?
Conflicting evidence or recommended not to use with some - short term pain control with others
32
What is the patient rx for computer use?
Use computer mouse less, alternate hands, use arrow keys or touch screens - keyboards with lower strike force
33
What/when are orthoses used for with CTS?
Neural wrist splint especially at night , also during the day when night only use is ineffective
34
What can we immobilize with CTS?
MTP joints PRN
35
What joint mobs can be done with CTS?
Joint mobilizations for neck, forearm, wrist, for short term progress
36
What are better for CTS: neural glides or tendon glides?
Tendon glides
37
What is the purpose of tendon glides?
The 10 tendons don't all move at the same time, need to slide on each other, sheath can build up scar tissues which are then needed to be broken up
38
What MET is recommended for CTS?
Lack of research for CTS :(
39
What treatment combination is helpful for CTS?
Orthoses and stretching
40
What is the frequency of sessions for CTS?
3 weekly sessions and a HEP - combination of STM, neural and tendon glides
41
What are the results after the recommended session frequency and combination of treatments?
Better pain relief and functional abilities at 1 and 3 months, equal to sx with pain and function at 6 and 12 months
42
What amount of patients are helped by a cortisone injection with CTS?
1/3
43
What is the surgery for CTS?
A carpal tunnel release, cutting of the transverse ligament
44
What is the CTS sx similar to? (Another treatment)
3 manual therapy treatments following 12 months of symptoms
45
What is the rx for manual therapy treatments for CTS?
From neck to hand improved symptoms and punch tip grip force
46
What is damage to the median nerve referred to as?
Ape hand
47
What does the denervation of the median nerve result in?
- weakness in the thenar muscles - thenar atrophy with the thumb more in the plane of the hand - Inability to flex, oppose or abduct the thumb
48
What is the denervation of the ulnar nerve known as?
Claw hand
49
What are symptoms of the denervation of the ulnar nerve?
- Atrophy of hypothenar eminence - Deficient interossei muscles - claw like deformity
50
What systemic disease can cause innervation issues?
Diabetes
51
What are some bone and joint problems in the hand?
- RA - Fractures - Dislocations
52
What is the most common of all fractures?
Colles
53
What population is Colle's fracture most common in?
Biological women middle aged and older
54
What is the etiology for Colles?
FOOSH
55
What structures are involved with Colles?
The distal radius breaks
56
Where does the distal radius break with Colles?
Within 2.5 cm of the wrist, displaced dorsally
57
What is Colle's also known as?
Dinner fork deformity
58
What is reverse Colle's due to?
A fall on the dorsum of the hand
59
What is the most common carpal to be fractured?
Scaphoid
60
What is the etiology of a scaphoid fracture?
FOOSH
61
What is a complication of a scaphoid fracture?
Avascular necrosis may be an issue in the proximal and distal poles of the scaphoid, circulation complicates healing
62
What are S&S of a scaphoid fracture?
* Pain at anatomic snuffbox is primary complaint * Functional test; pain with thumb to index pinch * ROM - pain with wrist extension and pronation * special tests - stethoscope test
63
What is a Boxer's (Fighter's) fracture?
Fracture at the neck of the 2nd, 3rd, 4th, or 5th fingers **MOST common of fingers
64
What is Bennett's Fracture?
Proximal 1st MC MOST common of thumb
65
What is the MOST common fracture of the thumb?
Bennett's fracture
66
What is the PT rx for fractures?
- Deal with scan findings - may be accessory motion may be stability tests - Find what is weak - is there ligament damage?
67
What is the etiology of dislocations?
FOOSH
68
What carpal is most commonly dislocated?
Lunate
69
What other stabilizing structure is attached to the lunate?
Disc and fibrocartilage
70
Where is the most common instability in the hand?
Scapho-lunate joint
71
What special tests can be done for the scapho-lunate joint?
Watson's - dorsal glide of scaphoid moving from ulnar deviation and extension to radial deviation and flexion
72
What is the PT rx for dislocations in the hand?
- work on tissue proliferation/integrity if damage - Work on stability if needed - May splint if muscle system can't make up all the difference
