From the Guidelines
A Strassburg sock is a highly recommended treatment for plantar fasciitis, as it helps to maintain the foot in a dorsiflexed position while sleeping, reducing morning pain and promoting healing. The sock works by keeping the plantar fascia and Achilles tendon gently stretched overnight, preventing the tissue from contracting and reducing the painful first steps in the morning that characterize plantar fasciitis 1. To use a Strassburg sock, put it on before bed, adjust the attached strap to create a comfortable tension that holds the toes upward, and wear it throughout the night.
Some key points to consider when using a Strassburg sock include:
- Wearing it nightly for at least 1-3 months while symptoms are acute, then as needed for maintenance
- Using it as part of a comprehensive treatment plan that includes daytime stretching exercises, appropriate footwear, and possibly anti-inflammatory medications
- Adjusting the tension to a tolerable level, and removing the sock if it causes numbness, tingling, or severe pain
- Being aware that some discomfort is normal during initial use, but it should be manageable
The effectiveness of the Strassburg sock stems from preventing the plantar fascia from tightening during sleep, which helps maintain flexibility and promotes healing of the inflamed tissue over time. According to the American College of Foot and Ankle Surgeons, night splinting, which includes the use of a Strassburg sock, is a recommended treatment for plantar fasciitis if initial treatment measures do not show improvement after six weeks 1.
From the Research
Uses for Strassburg Sock
The Strassburg sock, also known as a night sock or dorsal night splint, is used to manage plantar fasciitis. The main purpose of this sock is to:
- Hold the foot in a dorsiflexed position, which helps to stretch the plantar fascia and reduce pain
- Provide support and stability to the foot and ankle during sleep
Benefits of Using a Strassburg Sock
Studies have shown that using a Strassburg sock can be effective in reducing pain and improving function in patients with plantar fasciitis 2, 3, 4, 5. The benefits of using a Strassburg sock include:
- Reduced pain and stiffness in the morning
- Improved function and mobility
- Increased support and stability for the foot and ankle
- Can be used in combination with other treatments, such as foot orthoses and physical therapy
How it Works
The Strassburg sock works by holding the foot in a dorsiflexed position, which helps to stretch the plantar fascia and reduce tension on the heel 3, 4. This can help to reduce pain and inflammation, and improve function and mobility. The sock can be worn at night, and can be adjusted to fit individual foot shapes and sizes.
Effectiveness
Studies have shown that using a Strassburg sock can be effective in reducing pain and improving function in patients with plantar fasciitis 2, 3, 4, 5. One study found that 88% of patients who used a dorsiflexion night splint improved, and 80% of involved feet improved subjectively 3. Another study found that patients who used a night splint had significantly higher improvements in pain and function scores compared to those who did not use a night splint 5.
Combination with Other Treatments
The Strassburg sock can be used in combination with other treatments, such as foot orthoses and physical therapy 2, 4. One study found that the combination of a foot orthosis and a dorsiflexion night splint was more effective than a foot orthosis alone in relieving foot pain in patients with plantar fasciitis 4.
