ORTHOSIS

ORTHOSIS

Definition

• An orthosis is an external device applied on the body to limit motion, correct deformity, reduce axial loading, or improve function in a certain segment of the body.

FUNCTIONS

• Prevention of deformity

• Correction of deformity

• Maintenance of correction

• Instability control

• Relieving weight bearing

• Facilitating ambulation

• Relieving pain

CLASSIFICATION

• General– Static and Dynamic Eg..

• Functional– Supportive, Functional, Corrective &

Protective Eg..

• Regional– Upper & Lower extremity and Spine

GENERAL

• Static orthoses: No movement allowed – Eg. Cockup splint

• Dynamic/functional orthoses: Permits movement. – Eg. Lively splint

Functional

• Supportive– Eg. Hip Knee Ankle Foot Orthosis (Calipers)

• Functional Orthosis– Eg., Foot drop splint (Ankle Foot orthosis)

• Corrective Orthosis– Eg. Dennis Brown splint (Club foot boot)

• Protective Orthosis– Eg. Cockup splint (wrist drop splint)

• Upper extremity

• Lower extremity

• Spine

prolonged use • Decreased pulmonary

capacity • Difficulty with transfers

• Increased energy expenditure with ambulation

• Difficulty donning and doffing orthosis

• Psychological and physical dependency

• Increased segmental motion at ends of the orthosis

• Unsightly appearance • Poor patient compliance

Orthotic Prescription

• Muscle power

• Deformities
