UE Orthoses Flashcards
function of static orthosis
- Immobilizes a joint
- Provides stabilization, protection, and support to a body segment
type of orthotic?
Miami J, TLSO
static orthotic
function of serial static orthotic
Applied with the joints, soft tissue, or musculotendinous units they cross in a lengthened position
type of orthotic?
serial casting, OTC splints
serial static orthotic
dynamic orthotics use a(n) ____ force
elastic
function of dynamic orthotics
Mobilize specific tissues to achieve increases in ROM
type of orthotic?
hand splint with finger outriggers
dynamic orthotics
function of static progressive orthotic
Tissue mobilization through low-load to the tissue’s end range in one direction over a period of time
what type of force do static progressive orthotics use?
static, nonelastic
orthotics use a _____ point pressure system
3
pressure = ___/____
pressure = force/area
Orthotic acts as a ____ force proximally and distally to the forces of the forearm and hand
counter
factors to consider for positioning of the hand
Diagnosis
Healing time frame
Intervention goals
Position of function for hand
20-30 deg wrist extension
35-45 deg MTP flexion
45 deg PIP flexion
Relaxed flexed position of DIP
Palmar abduction of thumb
Position of rest for hand
(sock puppet)
30-40 deg wrist extension
60-90 deg MTP flexion
PIP & DIP extension
Palmar abduction of thumb
Pull of dynamic component MUST be ____ to long axis of bone
PERPENDICULAR
must maintain ____ pull of outriggers as position changes
90 degree
main difference between low profile and high profile outriggers
low - act as pulley for dynamic components
high - direct attachment of elastic
which needs more adjustments? low profile or high profile outriggers
low profile
which has more tension force? low profile or high profile outriggers
low profile
UE orthotic precautions
Vascular compromise
Nerve injury due to pressure
Biomechanical principles and joint alignment
Minimize immobilization of non-involved structures
Impairment of function
Infection
Skin injury (maceration)
Impaired mentation
Compliance
Safety
