A lower limb orthosis is an external device which is applied or attached to the lower body. It improves function by controlling motion and providing support.
Some of the lower extremity orthothic devices are listed below:
AFOs (Ankle Foot Orthoses) are designed for patients with gait deviations and foot and ankle deformities relating to muscle weakness, contractures or skeletal alignment abnormalities. They are used for CVA, cerebral palsy, muscular dystrophy, spinal bifida, other neuromuscular disorders, diabetic Charcot foot, crushing injuries, contractures, burns, M/L ankle instabilities, habitual toe walkers, prevention of deformity, post-operative stabilization.
Dynamic AFO is a functional, active resistance ankle brace that incorporates a spring loaded, adjustable tension mechanism that applies continuous dynamic stress in either flexion or extension to aid in resolving ankle joint stiffness or diminished range of motion. It helps in maintaining proper musculoskeletal alignment to prevent deformity and maintain soft tissue extensibility and ROM of the foot and ankle resulting from illness, surgery, joint trauma or congenital-abnormalities.
Ankle Supports are designed to provide medial lateral ankle support in stance phase. These come in different styles and materials, from off-the-shelf pneumatic air cast splints to lace up canvas ankle supports. They are used to correct ankle instability, avulsion fractures, sprains, inversion-eversion control, ligamentous injuries, minor fractures of the foot and ankle, protection of the ankle and foot during rehabilitation.
Ground Reaction AFO is a custom molded thermoplastic orthosis containing a rigid anterior tibial section, ankle and foot plate designed to provide posteriorly directed forces just below the knee to promote knee extension in stance phase. It is used for patients with neuromuscular disorders resulting in weak quadriceps that exhibit a 'crouched' type gait during stance phase.
