UE Orthotics Flashcards
UE Orthotics Named
-Shoulder, Elbow, Wrist, Hand, Finger
-SEWHFOrthotics
Immobilization Orthotic
-place structure at most comfortable or resting position
-s/s relief, maintain tissue length, functional use, protection
Mobilization Orthotic
-moving of stretching tissues
-facilitation of cell growth and organization of new cells/collagen
-substitute for dec motion
-inc PROM
Ex:
-Serial static
-static progressive
-Dynamic orthoses
Restriction Orthosis
-blocks motion
-limits motion after injury
-can allow some motion in certain directions
-join stability
-regain functional use of hand
Static Orthosis
-immobilizes joint
-priviides stabilization, protection and support
Serial Static Orthosis
-joints and soft tissue and units they cross in a lengthened position and worn for extended periods of time
-removed for therapy
-temporary
Dynamic Orthosis
-elastic type to mobilize specific tissues
-pull of dynamic component must be perpendicular to bone to maintain 90 deg
Static Progressive Orthosis
-tissue mobilization by applying low-load to tissues end range
-force can be elastic or non elastic
-progressive adjustments
Mechanical Principles
-3 points of pressure for equilibrium
-orthotic is a counterforce and strap is reiprocal middle force
-increase Area of force to disperse pressure
-Pressure: Force/Area
Hand Position for Funtion
Wrist: 20-30 ext
MP: 35-45 flex
PIP: 45 deg flex
DIP: relaxed
Thumb: palmar ABD
Hand Position for Rest
Wrist: 30-40 ext
MP: 60-90 flex
PIP: Ext
DIP: Ext
Thumb: palmar ABD
-Crocodile hand
Dynamic Components: Outriggers
-used as a pulley or to attach elastic components
Low Profile: pulley for dynamic components
-more adjustments needed
-more tension
-more attraction
High Profile: for direct attachment of elastic components
-less esthetically pleasing
-inconvient
-less adjustments needs
-less force needed
Precautions for Orthotics
-vascular compromise
-nerve injury from pressure
-biomechanics
-impairment of function
-skin injury
-infection
-impaired mentation
