Brief Summary

The gastrocnemius muscles, which form the upper part of the calf, can suffer from retraction, a common but often under-diagnosed condition, which can be a risk factor for plantar fasciitis. Retraction can be treated medically, by stretching, or surgically, by lengthening the muscles. Gastrocnemius retraction is difficult to measure, but tests such as the Ankle Dorsiflexion Index (ADI) provide a more accurate assessment. Knowing the prevalence of this retraction in patients suffering from plantar fasciitis would enable us to improve diagnostic criteria and better target treatments. Surgical lengthening of the gastrocnemius, particularly by tenotomy, is effective in cases of chronic plantar fasciitis, even without apparent muscle retraction.

Conditions

Plantar Fasciitis

Outcome Measures

Primary Outcomes (1)

• Prevalence of gastrocnemius muscle retraction in patients with plantar fasciitis

  retraction of the gastrocnemius muscles will be defined by an ADI of less than 13° measured by a digital inclinometer

  At Day 0

Secondary Outcomes (12)

• correlation between ADI measurement and Manchester Oxford Foot Questionnaire (MOXFQ)

  At Day 0

• correlation between ADI measurement and pain Visual Analog Scale (VAS)

  At Day 0

• Evolution of Visual Analog Scale (VAS)

  between Day 0 and Week 8

• Evolution of Visual Analog Scale (VAS)

  between Day 0 and Week 16

• Evolution of Visual Analog Scale (VAS)

  between Day0 and Week 24
