Best Method for Making Orthotics

Direct Orthotics

Best Method

The best method is to use advanced 3D Kinematic Imaging (3DO) 

to capture the foot using a 3D imager that will analyze both STATIC (non-movement) and DYNAMIC (movement) data.   The reason is quite simple.   The foot and limb work differently in non movement (static) states then it does in movement (dynamic) states.    In Dynamic States, Mass displacement, balance, linear and sheer pressures, Gait analysis, mass displacement contributes significantly to disease states and should be analyzed.  This can only be done using high technology 3D imaging sensors which provides objective data about a patients biomechanical problems.   

More Data = Better Results = Better Care

1. Mass Displacement Analysis
2. Body Balance
3. Linear Pressure Analysis
4. Sheer Pressure Analysis 
5. Motion Analysis
6. Gait Analysis
7. 3D Plantar Geometry 
8. Neutral Joint Positioning computed by Digital Imager Live Software 

Older Methods 

Plaster Neutral Joint Casting

For 90 years Orthotics have been made by casting patients using plaster sheets where rearfoot and midfoot joints are aligned by a foot specialist physician.   The casts are applied and then allowed to dry and then are removed.  Many times a range of or motion exam and or x rays are used to determine where the physician believes the joints are in proper alignment and then tried to capture that correction from the positive cast.   

Problems: 

1. Improper cast impression technique (common errors)
2. Cast distortion by removal, shipping or inadequate drying
3. Damage to cast at Laboratory through pouring liquid plaster for positive mold 
4. Improper balancing of rearfoot and forefoot 
5. Improper thermo-pressing (suctioning)
