1. Introduction to the Biomechanics of Orthoses Understanding Orthotic Devices associate professor dr. farah kamil

2. What are Orthoses? Orthoses are devices applied externally to the body to modify the structural and functional characteristics of the neuromuscular and skeletal systems. Purpose: To support, align, prevent, or correct deformities or to improve function. Examples: Foot orthoses, ankle-foot orthoses, knee-ankle-foot orthoses, spinal orthoses.

3. Introduction to Orthoses (Statistics) Statistics: • Over 30 million people in the U.S. use orthotic devices. • The global orthotic devices market is expected to reach $6.8 billion by 2027. Insert statistics chart/image here

4. Types of Orthoses (Details) Foot Orthoses: Insoles, arch supports Ankle-Foot Orthoses: For stability and mobility Knee-Ankle-Foot Orthoses: Full-leg support Hip-Knee-Ankle-Foot Orthoses: For entire lower limb Spinal Orthoses: Braces for spinal alignment Upper Limb Orthoses: For arms and hands Insert detailed images of orthoses here

5. Importance of Biomechanics in Orthoses Definition of Biomechanics: The study of the mechanical laws relating to the movement or structure of living organisms. Role in Orthoses: Understanding forces, movements, and how orthoses can aid in proper alignment and movement.

6. Types of Forces in Biomechanics Compression: Force that squeezes or compresses tissue. Tension: Force that stretches or elongates tissue. Shear: Force that slides tissues in opposite directions.

7. Moments and Torque Moments: The rotational effect of a force applied at a distance from the axis of rotation. Torque: A measure of how much a force acting on an object causes that object to rotate.

8. Stress and Strain in Biological Tissues Stress: The internal force per unit area within materials that arise from externally applied forces. Strain: The deformation or displacement of material that results from an applied stress.

9. Equilibrium and Balance Equilibrium: The state where the sum of forces and moments on a body is zero. Balance: The ability to maintain the center of mass over the base of support.

10. Foot Orthoses Biomechanics Function: Distribute pressure, support arches, correct alignment Mechanics: Alter force distribution, enhance gait mechanics Example: Arch supports reduce pronation Insert image of foot orthosis biomechanics here

11. Ankle-Foot Orthoses Biomechanics Function: Stabilize the ankle, assist in walking Mechanics: Control plantarflexion/dorsiflexion, medial/lateral stability Example: AFOs for drop foot condition Insert image of AFO biomechanics here

12. Spinal Orthoses Biomechanics Function: Support and align the spine Mechanics: Reduce load on vertebrae, control spinal curvature Example: TLSO (thoracolumbosacral orthosis) for scoliosis Insert image of spinal orthosis biomechanics here

13. Advancements in Orthotic Technology Materials: Carbon fiber, thermoplastics. Customization: 3D printing, custom molding. Smart Orthoses: Sensors, feedback systems.
