The Science Behind Custom Orthotic Design in Derry, New Hampshire

At Foot & Ankle Associates of Southern NH, located in Derry, New Hampshire, we understand the critical role that custom orthotics play in enhancing foot health. Many patients come to us seeking relief from various foot conditions, and the science behind custom orthotic design is integral to our approach to treatment. This article will explore the anatomy of the foot, common conditions that benefit from orthotics, the design process, and how custom orthotics can provide significant relief and improve overall mobility.

What Causes Foot Pain?

Foot pain can result from a variety of factors, including:

  • Injury: Sprains, fractures, and tendon injuries can cause acute pain.
  • Overuse: Conditions like plantar fasciitis and Achilles tendinitis often stem from repetitive strain.
  • Structural Issues: Conditions such as flat feet or high arches lead to an uneven distribution of weight.
  • Diabetes: Can result in neuropathy and poor circulation, leading to foot complications.

How Do Custom Orthotics Work?

Custom orthotics are specially designed shoe inserts that provide support, cushioning, and correct alignment for the feet. These devices work by redistributing pressure across the foot, promoting proper posture and alleviating pain. They can be crafted to address specific conditions, such as:

  • Plantar fasciitis: Reduces strain on the fascia and alleviates heel pain.
  • Flat feet: Supports the arch, preventing overpronation.
  • Metatarsalgia: Redistributes weight away from the metatarsal heads, alleviating pain.
  • Diabetic foot conditions: Provides cushioning and reduces pressure points.

What is the Custom Orthotic Design Process?

At Foot & Ankle Associates of Southern NH, we follow a comprehensive process to ensure the orthotics are tailored to each patient's unique anatomy:

1. Initial Assessment

Our podiatrists conduct a thorough evaluation of your foot structure, gait, and any existing conditions. This assessment may include:

  • Clinical history.
  • Physical examination.
  • Gait analysis.

2. Impressions and Measurements

To create precise orthotics, we take detailed impressions of your feet using 3D scanning or plaster cast techniques to capture the foot's shape and alignment correctly.

3. Design and Materials

Based on the assessment, we select specific materials and designs that provide the necessary support and comfort, such as EVA foam, cork, or thermoplastics. Each material has unique properties that influence cushioning, support, and durability.

4. Fabrication

Once the design is finalized, our lab fabricates the orthotics. State-of-the-art technology ensures accuracy and quality, resulting in a product that will reliably relieve pain and improve function.

5. Fitting and Adjustment

After fabrication, we conduct a fitting appointment to ensure the orthotic devices interact properly with your footwear and provide the anticipated support. Adjustments may be made to maximize comfort.

How Long Do Custom Orthotics Last?

The lifespan of custom orthotics varies based on activity level, body weight, and the materials used. Generally, high-quality orthotics can last from one to three years. Regular check-ups with our podiatrists at Foot & Ankle Associates of Southern NH can help you assess their condition and effectiveness.

Are Custom Orthotics Covered by Insurance?

Many insurance plans offer coverage for custom orthotics, especially if prescribed by a licensed podiatrist. We recommend checking with your insurance provider to understand the specifics of your coverage. Our team can assist with any necessary documentation to help you maximize your benefits.
