Figure 8 Ankle Brace: Application, Proper Fit, and Care

How Do You Wear a Figure 8 Ankle Brace?

Proper application of a Figure 8 ankle brace is crucial for maximizing its effectiveness in providing stability and support, mimicking the protective patterns of athletic taping to prevent injury or aid in recovery.

Understanding the Figure 8 Ankle Brace

A Figure 8 ankle brace is a common orthopedic device designed to support the ankle joint by mimicking the supportive strapping pattern of athletic tape. Its name derives from the "figure-eight" configuration created by its straps around the ankle and foot.

• Indications for Use: These braces are frequently recommended for individuals recovering from ankle sprains (particularly inversion sprains), those with chronic ankle instability, or athletes seeking prophylactic support during high-impact or multi-directional sports.
• Mechanism of Action: The brace works by limiting excessive inversion and eversion (sideways rolling) of the ankle, which are common mechanisms of sprain. It also provides proprioceptive feedback, meaning it helps the wearer's body better sense the position of their ankle in space, aiding in more stable movement and quicker reactive muscle engagement. While offering significant support, a well-designed figure 8 brace still allows for necessary plantarflexion (pointing toes down) and dorsiflexion (pointing toes up), preserving functional range of motion.

Step-by-Step Guide to Applying a Figure 8 Ankle Brace

While specific designs may vary, most Figure 8 ankle braces follow a general application process. Always refer to the manufacturer's specific instructions, but the following steps provide a comprehensive guide:

1. Preparation:

   • Ensure your foot and the inside of the brace are clean and dry.
   • Wear a thin, moisture-wicking sock underneath the brace. This helps prevent chafing and absorbs sweat.
   • Sit down in a comfortable position where you can easily reach your foot.

2. Position the Foot:

   • Place your foot into the brace. Ensure your heel is snugly seated at the back of the brace.
   • Your foot should be at a 90-degree angle (neutral position) to your shin, or slightly dorsiflexed (toes pulled slightly up). This is critical for optimal support. Avoid applying the brace with your foot pointed down (plantarflexed).

3. Secure the Main Body (if applicable):

   • If your brace has laces, lace it up from the bottom to the top, ensuring even tension. Do not overtighten, but the main boot should feel snug.
   • If it uses a main Velcro closure, secure it firmly around the ankle.

4. Apply the Figure 8 Straps: This is the core of the brace's support. Most Figure 8 braces have two main straps that originate near the top of the ankle on either side.

   • Strap 1 (Often Lateral-to-Medial):

     • Take the strap that originates from the outside (lateral) of your ankle.
     • Pull it down and forward, crossing under the arch of your foot.
     • Continue pulling it up and across the inside (medial) of your ankle.
     • Secure the strap to the Velcro patch on the side of the brace, typically on the outside. This strap helps restrict inversion.

   • Strap 2 (Often Medial-to-Lateral):

     • Take the strap that originates from the inside (medial) of your ankle.
     • Pull it down and forward, crossing under the arch of your foot (often overlapping the first strap).
     • Continue pulling it up and across the outside (lateral) of your ankle.
     • Secure the strap to the Velcro patch on the side of the brace, typically on the inside. This strap helps restrict eversion.

   • Visualizing the "8": When both straps are applied correctly, they should cross over the top of your foot (instep) and also cross under the arch, creating the characteristic "figure 8" pattern around your ankle.

5. Secure Top Straps (if applicable):

   • Many braces have an additional top strap or two that wrap around the upper ankle/lower shin. Secure these firmly to provide additional compression and keep the brace from sliding down.

Proper Fit and Comfort

A correctly applied Figure 8 ankle brace should provide firm, comfortable support without causing pain, numbness, or restricting circulation.

• Signs of a Good Fit:

  • The brace feels snug and supportive, limiting excessive side-to-side ankle movement.
  • You can comfortably move your foot up and down (dorsiflexion and plantarflexion) within a functional range.
  • There are no pressure points, pinching, or rubbing.
  • Your toes remain warm and maintain normal color.
  • You can fit one finger comfortably under the main laces or straps.

• Signs of a Poor Fit (Requires Adjustment):

  • Too Tight: Numbness, tingling, coldness, or blueness in the toes, significant discomfort or pain, skin indentations, or redness. Loosen the straps and reapply.
  • Too Loose: The brace slides around, allows excessive ankle movement, or feels ineffective. Tighten the laces and straps, ensuring the figure 8 pattern is taut.
  • Wrinkling/Bunching: This can lead to hot spots or blisters. Ensure the sock is smooth and the brace is applied without creases.

When to Use and When to Seek Professional Advice

Figure 8 ankle braces are valuable tools for ankle support, but their use should be guided by your specific needs and, ideally, professional advice.

• Appropriate Use:

  • Post-Injury Support: After an acute ankle sprain, once initial swelling has subsided and weight-bearing is tolerable, a brace can facilitate a safe return to activity by providing stability.
  • Chronic Instability: For individuals prone to repeated ankle sprains due to ligamentous laxity, wearing a brace during physical activity can significantly reduce the risk of re-injury.
  • Prophylactic Use: Athletes in sports with a high risk of ankle injuries (e.g., basketball, volleyball, soccer) may wear these braces preventatively.

• When to Seek Professional Advice:

  • Severe Pain or Inability to Bear Weight: These are signs of a potentially more serious injury (e.g., fracture, severe sprain) that requires immediate medical attention.
  • Significant Swelling, Bruising, or Deformity: A healthcare professional should evaluate these symptoms.
  • Numbness or Tingling in the Foot/Toes: This could indicate nerve involvement or excessive compression.
  • Symptoms Worsen or Do Not Improve: If your pain or instability persists despite brace use and rest, consult a doctor or physical therapist.
  • Unsure of Diagnosis: Never self-diagnose a significant injury. A professional can provide an accurate diagnosis and recommend the most appropriate treatment plan, which may include specific bracing, physical therapy, or other interventions.

Maintenance and Care of Your Ankle Brace

Proper care extends the life of your brace and maintains its hygienic integrity.

• Cleaning: Most Figure 8 ankle braces can be hand-washed with mild soap (e.g., dish soap or laundry detergent) and cold water. Avoid harsh chemicals or bleach.
• Drying: Air dry completely before storing or re-wearing. Do not put it in a dryer, as high heat can damage the materials and elastic components.
• Storage: Store in a clean, dry place away from direct sunlight or extreme temperatures.
• Inspection: Regularly inspect the brace for signs of wear and tear, such as frayed straps, stretched elastic, or damaged Velcro. Replace the brace when it no longer provides adequate support.

By understanding the proper application and care of your Figure 8 ankle brace, you can effectively leverage this tool to support ankle health, enhance performance, and prevent injuries.
