Foot dorsiflexor tendinopathy: understanding your ankle pain and getting back to activity

What is foot dorsiflexor tendinopathy?

Dorsiflexor muscle anatomy

The foot dorsiflexor muscles, located at the front of the leg, lift the foot and toes during each swing phase of the stride (so the foot doesn’t drag on the ground) and control the heel strike on landing. Their tendons pass over the top of the ankle before reaching the foot. This tendinopathy particularly affects activities involving downhill running or frequent changes of pace.

Why do these tendons become painful?

Pain appears when the dorsiflexors are repeatedly overloaded eccentrically, particularly through braking at each footstrike, typically during downhill running or a sudden increase in running volume. Unsuitable or overly tight footwear across the top of the foot can also irritate these tendons.

Symptoms and diagnosis of foot dorsiflexor tendinopathy

Typical pain and its triggers

The pain sits on the top of the ankle and foot, along the path of the dorsiflexor tendons. It’s triggered or worsened by downhill running, prolonged walking on hilly terrain, or wearing shoes with tight lacing across the top of the foot. Discomfort on stretching into plantar flexion or when loaded against resistance is also common.

How symptoms progress without treatment

Without treatment, the pain tends to settle in and appear earlier and earlier during exertion, particularly if the volume of downhill running stays high or the footwear isn’t adjusted.

Differential diagnosis

Several conditions affecting the front of the ankle and lower leg can resemble foot dorsiflexor tendinopathy:[1]

• Tibialis anterior muscle strain, which tends to appear suddenly during exertion
• Anterior tibial shin splints, with more widespread pain along the shin
• Ankle sprain, if there’s an associated recent trauma

Causes and risk factors

Foot dorsiflexor tendinopathy develops following repeated eccentric loading that exceeds the capacity of these tendons.[2]

Biomechanical and personal factors

• A sudden increase in running volume or intensity, particularly downhill
• Unsuitable or overly tight footwear across the top of the foot
• Reduced ankle mobility, which increases demand on the dorsiflexors
• A strength deficit in the dorsiflexors relative to the load required

Which sports contribute to foot dorsiflexor tendinopathy?

Any sport involving downhill running or frequent changes of pace exposes these tendons:

• Downhill running and trail running
• Hiking on hilly terrain
• Football and sports with repeated sprints
• Cross-country skiing and Nordic walking
• Sports with tight-fitting footwear across the top of the foot

Treating foot dorsiflexor tendinopathy in rehab with a sports physio

The goal of treatment is to progressively strengthen the dorsiflexors to restore their capacity to control footstrike, particularly through eccentric work.

1. 1Reducing pain and managing load
2. 2Ankle mobility
3. 3Isometric strengthening
4. 4Progressive concentric strengthening
5. 5Eccentric strengthening
6. 6Ankle proprioceptive work
7. 7Correcting technique and footing
8. 8Strengthening under sport-specific load
9. 9Progressive return to running
10. 10Return to competition

“It’s not that the tendon is fragile, it’s that the load needs to be better dosed and distributed.”

Eccentric strengthening, the cornerstone of treatment

Strengthening the dorsiflexors, particularly through eccentric work to replicate their footstrike-braking function, restores their capacity to withstand the load specific to running, especially downhill.[2]

In brief

• Progressive strengthening of the dorsiflexors
• Specific eccentric work
• Adjusting footwear if needed
• Gradual return: mobility, then load, then sport

Should you rest or keep playing sport?

Total rest is generally not necessary. It’s better to temporarily adapt the volume of downhill running that clearly reproduces the pain, while starting strengthening as soon as possible.

When should you see a specialist for this tendinopathy?

If the pain persists for more than three to four weeks despite adapting your activities, a medical opinion is recommended to rule out another cause of pain on the top of the foot.

Expected recovery timeline for foot dorsiflexor tendinopathy

Clear improvement is generally seen within a few weeks with a well-suited eccentric strengthening programme, by first reducing the downhill load before progressively reintroducing it.

Preventing recurrence

Once the pain has settled, several measures can help prevent it from coming back:

• Keep up regular strengthening of the dorsiflexors, even well after the painful episode
• Progress running volume and downhill distance cautiously
• Check and adjust your shoe lacing across the top of the foot
• Work on ankle mobility to limit overloading the dorsiflexors

The HOPP care programmes to treat your foot dorsiflexor tendinopathy and get back to sport

This tendinopathy requires progressive eccentric strengthening. HOPP offers you a precise exercise programme, allowing you to get back to your activities as quickly as possible.

The programme runs from 3 to 9 weeks depending on the injury and ends with a reconditioning phase allowing a return to competition in the best possible conditions. Each programme is designed by the HOPP team, made up of two sports physiotherapists who are experts in assessing and treating athletes. You’ll also find theoretical content throughout your progression, so you master every aspect of your recovery and can adjust your treatment independently. If needed, our team of physiotherapists is on hand to support you.

A programme that adapts to you every day

Every day, how you feel (RPE) is factored in to automatically adjust the rest of your programme: more load if all is well, a bit less if your ankle is complaining. This daily personalisation is what makes the difference compared to a fixed, paper-based programme.
