1. Three jaw chuck - pencil grip, two fingers on the thumb
2. Lateral grip - key grip
3. Spherical - holding a ball or turning the doorknob, or opening a jar; the fingers are abducted in this grip
4. Cylindrical - grabbing a bottle; fingers are adducted
5. Hood - carrying a bag handle
6. Tip - thumb and first finger (like picking up a coin)
7. Palmar - lumbrical, holding a plate

What is the functional position of the wrist?

[image]

• Wrist - 30 degrees
• MP's - 20 degrees
• IP's & DIP's - 5 - 15 degrees
• Wrist in radial deviation
• Thumb in opposition
• Maintain web space
• Support palmar arch (maintained)

What are the two main categories

for an UE orthoses?

• Positional - brace is static; just holds the hand in one position
• Assistive - facilitates extension range or flexion range
  • a dynamic brace that will take on some of the work for the body part by use of a joint or a spring to help assist w/ motion

What type of brace is this?

What type of brace is this, and

What is the main goal of a positional

brace, and its most common use?

• Prevent further deformity and allow for prehension
  • most commonly used for flexion and internal rotation deformities
  • internal rotation - common for hemiparesis, CP pts, CVA pts

What type of brace is this?

[image]

• produce reciprocating motion such as wrist extension and finger flexion (tenodesis)
• utilizes rubber bands and/or jionts within the brace to create the motion

What is the difference between

a W.H.O. and a H.O.?

• W.H.O. - wrist/hand orthosis - it crosses the wrist
• H.O. - hand orthosis - it does not cross the wrist

• Custom - used for long term use, made to patient specifications
• Prefabricated - faster and easier, used mainly for short term issues

What motions are possible at the

scapulothoracic articulation?

• elevation
• depression
• protraction
• retreaction
• upward rotation
• downward rotation
• scapular tilt

The articulation is between the

glenoid fossa and the head of the humerus

• flexion - 0 - 180
• extension - 180 - 0
• hyperextension - 0 60
• abduction - 0 - 180
• adduction - 180 - 0
• horizontal abduction - 0 - 30
• horizontal adduction - 0 - 120
• internal rotation - 0 - 70
• external rotation - 0 - 90

The articulation is between the ulna and the humerus; and the proxilmal radial unlar joint

• flexion - 0 - 150
• extension - 0
• pronation & supination - 0 - 80

What are the articulations in the hand

and the thumb and the motions available?

MCP (metacarpophalageal joints),

the PIP, DIP, IP, and CMC

Hand

• MCP
  • flexion 0 - 80
  • hyperextension 0 - 45
•  PIP
  • flexion 0 - 100
• DIP
  • Flexion 0 - 90
  • Hyperextion 0 - 10

Thumb - saddle joint, CMC joint

• CMC
  • abduction 0 - 70
  • flexion 0 - 15
  • extension 0 - 20
  • opposition - tip of thumb to base of 5th digit
•  MCP
  • flexion 0 - 50
•  IP
  • flexion 0 - 80
