Night Splints for PTTD: How They Help and How to Use Them

If you wake up with stiff, painful feet every morning, night splints might help. Here’s what you need to know about using them for PTTD.

What are night splints

Night splints are braces you wear while you sleep. Unlike regular braces that support your foot in its usual position, night splints hold your ankle and foot in a gently flexed position. This stretches your calf muscles and Achilles tendon overnight.

The idea is simple: by keeping your calves stretched while you sleep, you reduce the morning stiffness that makes those first steps so painful.

How they help PTTD

Night splints address a few problems common with PTTD:

  • Morning stiffness — Tight calves make PTTD symptoms worse. Stretching them overnight can help
  • Calf contracture — As PTTD progresses, your calves can become permanently tight. Night splints help prevent this
  • Arch support — Some splints provide gentle support to your arch while you rest

They’re not a cure, but they’re a useful tool in your treatment arsenal.

Types of night splints

There are a few options:

  1. Boot-style splints — These look like small ski boots and hold your foot in position. Most common type.

  2. Sock-style splints — Lighter and more comfortable but may not provide as much stretch.

  3. Strap-based splints — Use velcro straps to hold your foot at an angle. More adjustable but can be tricky to get right.

  4. ** Dorsiflexion splints** — These actively pull your foot upward while you sleep, providing a deeper stretch.

Talk to your doctor about which type makes sense for your situation.

How to use them

Getting used to night splints takes some patience:

  • Start slowly — Wear them for 30 minutes the first night, then gradually increase
  • Wear them every night — Consistency matters more than duration
  • Adjust the straps — They should be snug but not cutting off circulation
  • Expect some discomfort at first — Your calves need time to adapt

Most people get comfortable within a week or two.

Benefits

  • Reduced morning stiffness
  • Calf muscle flexibility
  • Easier time with physical therapy exercises
  • Non-invasive treatment option

Potential drawbacks

  • Takes getting used to
  • Can be uncomfortable to sleep in
  • Not suitable for everyone (check with your doctor)
  • Results vary — they help some people more than others

How long to use them

This depends on your situation:

  • Some people use them for a few weeks during acute treatment
  • Others use them long-term to manage chronic PTTD
  • Your doctor can help you decide what’s right for you

If you’re not seeing improvement after a couple of months, talk to your doctor about whether to continue.
