At the end of the session the students should be able to: determine the classification used for upper extremity
orthoses determine diagnostic indications for upper extremity
orthoses determine the components and functions of upper
extremity orthoses discuss several static splints describe dynamic splints enumerate the purposes for prescribing dynamic
splints determine physiologic considerations in dynamic

Maintain the wrist in the neutral or mildly extended position
Immmobilizes the wrist while allowing full MCP flexion and thumb mobility

Contraindications: Active MCP synovitis Joint inflammation resulting to volar
subluxation and ulnar deviation
Disadvantages: Interferes with tactile sensibility on the
palmar surface of the hand Dorsal strap can impede lymphatic flow

Stronger mechanical support of wrist and freeing up some of the palmar surface for sensory input
Distributes pressure over the larger dorsal wrist surface area
Better tolerated by edematous hand

For burns: make adjustments as bandage bulk changes
Preventing infection: when open wound has exudates, clean splints with warm soapy water, hydrogen peroxide, or rubbing alcohol
Patients in the ICU: use sterile materials; follow protocol of the facility
RA patients benefit from thin thermoplast ( less than 1/8 inch )

Too great stretch Fatigued injury Failure
Too little stretch Atrophy and weaken Skin, tendons,
ligaments, and joint capsules will shorten in the absence of habitual tensile forces • Enough stretchEnough stretch
– Three degrees of gain in ROM per week, with a range of 1-10 deg, is acceptable (Cummings et al 1992 )
– High intensity short term stretching actually promotes stiffness
– The client should sense tension in the tissues but feel no pain
![Page 53: UPPER EXTREMITY ORTHOSIS (STATIC AND DYNAMIC)](https://reader033.vdocuments.net/reader033/viewer/2022061315/56814f35550346895dbccfb6/html5/thumbnails/53.jpg)
Hepburn, 1987 The stretch should not be perceived as a
“stretching” force until at least 1 hour has passed
Client should remain comfortable with the orthosis for up to 12 hours
After removal, the client should feel no more than a stiffness or mild ache

Objectives: To apply stretch to
tissues surrounding the oral cavity while permitting speech
To prevent contractures of lip and buccal tissues that may lead to limitation in oral opening
Indications: Facial and perioral burns
Wearing regimen Continuously worn Taken off only for
cleaning
Precaution The commisures(corners)
of the lips are prone to skin breakdown with improper fit and tension of the splint
