Orthosis

 Orthotics (Greek: Ορθός, romanized: ortho, lit. 'to straighten, to align') is a medical specialty that focuses on the design and application of orthoses. An orthosis (plural: orthoses) is "an externally applied device used to modify the structural and functional characteristics of the neuromuscular and skeletal system".^[1] An orthotist is the primary medical clinician responsible for the prescription, manufacture and management of orthoses.^[2] An orthosis may be used to:

• Control, guide, limit and/or immobilize an extremity, joint or body segment for a particular reason
• Restrict movement in a given direction
• Assist movement generally
• Reduce weight bearing forces for a particular purpose
• Aid rehabilitation from fractures after the removal of a cast
• Otherwise correct the shape and/or function of the body, to provide easier movement capability or reduce pain

Orthotics

Orthotics combines knowledge of anatomy and physiology, pathophysiology, biomechanics and engineering. Patients who benefit from an orthosis may have a condition such as spina bifida or cerebral palsy, or have experienced a spinal cord injury or stroke. Equally, orthoses are sometimes used prophylactically or to optimise performance in sport.[3]. At present, for prosthetic and orthotic interventions, the scientific literature does not provide sufficient high quality research to allow strong conclusions on their effectiveness and cost-effectiveness[4].
