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.

NONE
Enrollment

Ankle Dorsiflexion Index (ADI) measurement at D0 and W8
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
Time frame: At Day 0
correlation between ADI measurement and Manchester Oxford Foot Questionnaire (MOXFQ)
The Manchester Oxford Foot Questionnaire (MOXFQ) is used to measure the impact of foot pain on patients' quality of life. It consists of 16 questions. The raw scores of the scales are converted into a metric scale ranging from 0 to 100, where 100 indicates the maximum intensity of suffering or limitation.
Time frame: At Day 0
correlation between ADI measurement and pain Visual Analog Scale (VAS)
The VAS consists of a straight line where one extreme represents the total absence of pain and the other extreme, the most intense pain possible. Patients are asked to mark on this line the level of pain they feel at any given moment. Pain intensity is then measured according to the distance between the start of the scale (0) and the point where the patient placed his mark: * 0 cm (or the start of the scale): No pain * 10 cm (or the end of the scale): Maximum imaginable pain
Time frame: At Day 0
Evolution of Visual Analog Scale (VAS)
The VAS consists of a straight line where one extreme represents the total absence of pain and the other extreme, the most intense pain possible. Patients are asked to mark on this line the level of pain they feel at any given moment. Pain intensity is then measured according to the distance between the start of the scale (0) and the point where the patient placed his mark: - 0 cm (or the start of the scale): No pain - 10 cm (or the end of the scale): Maximum imaginable pain
Time frame: between Day 0 and Week 8
