Plantar Fasciitis

Lower Limb

Overview

Plantar fasciitis is inflammation of the plantar fascia, a thick connective tissue band running along the sole of the foot from the calcaneus to the metatarsal heads. It is the most common cause of heel pain, typically presenting with sharp pain at the medial calcaneal tuberosity, particularly in the morning or after periods of inactivity. The condition usually responds well to conservative management including manual therapy, stretching, and activity modification.

Pathophysiology

The plantar fascia experiences repetitive microtrauma due to excessive tensile loading, commonly from prolonged standing, running, or biomechanical dysfunction. Inflammation develops at the fascia's proximal insertion at the medial calcaneal tuberosity, though the condition often involves degenerative changes rather than true inflammation. Altered foot mechanics, reduced ankle dorsiflexion, and compensatory patterns in the kinetic chain contribute to persistent symptoms.

Typical Presentation

Site

Medial heel (calcaneal tuberosity), often radiating along the plantar fascia toward the forefoot; may be unilateral or bilateral

Quality

Sharp, stabbing, or burning pain; may describe tearing sensation; plantar arch discomfort

Intensity

Moderate to severe (5-8/10), worse in morning or after rest, improving with activity then worsening with prolonged loading

Aggravating

First steps after sleep or prolonged sitting, prolonged standing or walking, climbing stairs, tight footwear, high-impact activities (running, jumping), barefoot walking on hard surfaces, dorsiflexion of toes

Relieving

Gentle walking after warm-up, arch support or night splints, ice application, anti-inflammatory medication, rest and elevation, massage of plantar fascia

Associated

Stiffness in Achilles tendon, foot arch pain, reduced ankle dorsiflexion, altered gait pattern, possible calf tightness, morning stiffness

Orthopaedic Tests

Test descriptions are written with AI assistance from standard clinical texts. Where a test lists Sources, its description has been checked against them; those sources are independent and do not endorse OsteoKit. Accuracy figures and grades (A–D) appear only when checked against the published study; tests without one are marked “No accuracy study”.

Windlass Test

Procedure

Patient standing on a step with the toes over the edge, weight shared on both feet (weight-bearing version), or seated with the ankle supported. Passively extend (dorsiflex) the big toe at the MTP joint as far as it will go.

Positive Finding

Reproduction of the familiar pain at the inner heel or along the plantar fascia at end of range.

Sensitivity / Specificity

32% (7 of 22, weight-bearing)/100% (0 of 23 with other foot pain)

Reference: De Garceau D, Dean D, Requejo SM, Thordarson DB. The association between diagnosis of plantar fasciitis and Windlass test results. Foot Ankle Int. 2003;24(3):251-5.

Interpretation

A positive test supports plantar fasciitis; a negative test is common and does not rule it out. The weight-bearing version is more likely to be positive. Diagnosis rests mainly on the history (sharp pain with the first steps in the morning or after rest) and tenderness at the plantar fascia origin. From one study (De Garceau 2003): 22 patients with plantar fasciitis, 23 with other foot pain and 30 without foot problems. The weight-bearing test was positive in fewer than one in three patients with plantar fasciitis (the non-weight-bearing test in fewer still), but in none of the others. A positive test supports plantar fasciitis; a negative test rules little out. The diagnosis rests mainly on the history (first-step pain, pain at the medial heel) and tenderness at the plantar fascia origin.

Plantar Fascia Palpation Test

Procedure

Patient supine or seated with the ankle and toes dorsiflexed to tension the fascia. Palpate the medial calcaneal tubercle, then along the fascia into the arch. Compare with the other foot.

Positive Finding

Focal tenderness at the medial calcaneal tubercle that reproduces the familiar heel pain.

Interpretation

Tenderness at the fascia origin is a core feature of plantar fasciitis. Tenderness in the centre of the heel points more to the fat pad; pain when squeezing the heel from side to side suggests a calcaneal stress fracture; burning or tingling suggests nerve entrapment (tarsal tunnel or Baxter's nerve). A literature search (Europe PMC, September 2026) found no study reporting the diagnostic accuracy of this test, so no figure is shown. Tenderness at the medial calcaneal tubercle is nonetheless a core clinical feature of plantar fasciitis.

Heel Pain Provocation Test (Weight-Bearing Dorsiflexion)

Procedure

Ask about pain on the first steps in the morning or after sitting. In clinic, ask the patient to stand and rise onto the toes and back, or to walk a few steps after a period of rest.

Positive Finding

Heel pain that is worst on the first steps and eases after a few minutes of walking.

Interpretation

This 'first-step' pain pattern is typical of plantar fasciitis and is more useful than any single physical test. Pain that worsens steadily with walking, or night pain, should prompt a look for other causes. A literature search (Europe PMC, September 2026) found no study reporting the diagnostic accuracy of this test, so no figure is shown.

No accuracy study

Single Leg Stance Test

Procedure

Ask the patient to stand on the affected leg for up to 30 seconds, then rise onto the toes if able.

Positive Finding

Reproduction or increase of the familiar heel pain with single-leg loading.

Interpretation

A loading check that is useful for gauging irritability and tracking progress; it does not diagnose plantar fasciitis.

Sources

Not a diagnostic test

Silfverskiöld Test (Equinus Assessment)

Procedure

Patient supine. Hold the heel in neutral (slightly inverted to lock the subtalar joint) and dorsiflex the ankle with the knee straight, then with the knee bent to 90°. Compare the range in each position and with the other leg.

Positive Finding

Dorsiflexion is limited with the knee straight and improves when the knee is bent (gastrocnemius tightness), or limited in both positions (soleus or joint restriction).

Interpretation

Reduced ankle dorsiflexion is a recognised risk factor for plantar fasciitis and a treatment target (calf stretching, heel raise). It is not a diagnostic test.

No accuracy study

Medial Longitudinal Arch Palpation & Weight-Bearing Posture Assessment

Procedure

Observe the arch in sitting and standing, and during walking. Palpate along the medial arch and note foot posture.

Positive Finding

A low or collapsing arch in standing, a high rigid arch, or tenderness along the arch.

Interpretation

Describes foot posture, which may contribute to load on the plantar fascia and guide footwear or orthotic advice. Foot posture is only loosely linked to plantar fasciitis and is not diagnostic.

Osteopathic Techniques

First-line care is conservative: calf and plantar fascia stretching, taping, orthoses and footwear changes, with manual therapy or soft tissue massage as one option. Added to a home exercise programme, manual therapy eased short-term pain in a network meta-analysis, but a separate review rated its effect uncertain.

Technique

Soft tissue, foot and ankle
Grade C
Limited evidence: indirect or low-quality support only
Added to home exercise, manual therapy eased short-term pain in a network meta-analysis. A separate review rated its effect uncertain.

Rationale

Soft tissue to the plantar fascia, foot muscles and the tissues around the heel and ankle ligaments.

How it's done & evidence

How it's done

Hands-on kneading, stroking and sustained pressure to the plantar fascia, the small muscles of the foot and the tissues around the heel and the ankle ligaments.

Evidence in Plantar Fasciitis

Li 2026 (network meta-analysis, 24 RCTs, n=1240): manual therapy delivered with a home exercise programme gave a clinically significant short-term pain improvement over home exercise alone (moderate-quality evidence), without a clear gain in function. Gajardo-Valenzuela 2026 (4 RCTs, n=224, 3 at high risk of bias): the effects of manual therapy on pain and function are uncertain.

Region

Plantar foot and calf tender points

Technique

Counterstrain, foot and ankle tender points
Grade C
Limited evidence: indirect or low-quality support only
In one small placebo-controlled crossover trial (n=20), symptoms eased after counterstrain, most right after treatment and lasting about 48 hours.

Rationale

Gentle indirect technique: tender points in the foot and ankle are eased by passive positioning.

How it's done, cautions & evidence

How it's done

Find a tender point in the foot, ankle or calf. Passively move the foot and ankle into the position where the tenderness and tissue tension ease most, and hold it for about 90 seconds while monitoring the point. Return slowly to neutral and re-check.

Cautions

Do not use over an acute fracture, or in a patient who cannot give feedback.

Evidence in Plantar Fasciitis

Wynne 2006 (single-blind randomised crossover trial vs placebo, n=20): symptom severity improved after counterstrain, most immediately after treatment and lasting 48 hours. Calf reflex twitch mechanics changed but the electrically recorded reflexes did not. Short follow-up only.

Region

Subtalar and midtarsal joints

Technique

Articulation, ankle and foot
Contested
Evidence is conflicting across studies
Subtalar mobilisation beat conventional physiotherapy in one small trial. In others, adding ankle and midfoot mobilisation to stretching gave no extra benefit, and steroid injection worked faster than mobilisation plus stretching.

Rationale

Ankle, subtalar and midfoot glides, mainly to restore dorsiflexion and foot mobility.

How it's done, cautions & evidence

How it's done

Passive, rhythmic, low-velocity glides of the ankle (talocrural), subtalar, midfoot and toe joints, within or up to the end of the available range, often aimed at restoring ankle dorsiflexion.

Cautions

Before mobilising an acute ankle injury, check for fracture with the Ottawa ankle rules (tenderness over either malleolus), and palpate the base of the 5th metatarsal, the navicular and the midfoot for a Lisfranc injury.

Evidence in Plantar Fasciitis

Kashif 2021 (RCT, n=60, 52 completed): subtalar mobilisation with movement reduced pain and disability more than conventional physiotherapy. Shashua 2015 (RCT): adding ankle and midfoot mobilisation to stretching and ultrasound gave no extra benefit. Celik 2016 (RCT): steroid injection beat joint mobilisation plus stretching up to 12 weeks, with no difference at 1 year.

Region

Gastrocnemius-soleus complex and Achilles tendon

Technique

Soft tissue, calf and lower leg
Grade D
Low evidence: expert consensus or could not be verified against literature
No trials of calf soft tissue on its own in plantar fasciitis. Guideline-based care lists manual therapy or soft tissue massage and calf stretching.

Rationale

Calf and lower-leg soft tissue is usually given alongside a loading or stretching programme.

How it's done & evidence

How it's done

Hands-on kneading, stroking and sustained pressure to the calf (gastrocnemius and soleus), the Achilles tendon and the peroneal and tibial muscles of the lower leg. In trials it was given alongside exercise, such as eccentric calf loading.

Evidence in Plantar Fasciitis

Searched 25 Oct 2026: no trials of calf soft tissue alone. Indirect: StatPearls (Plantar Heel Pain), summarising the 2010 and 2014 clinical guidelines, lists manual therapy or soft tissue massage, and gastrocnemius/soleus and plantar fascia stretching, in the first 6 weeks of care.

Region

Gastrocnemius-soleus (ankle dorsiflexion)

Technique

Muscle energy, calf (gastrocnemius and soleus)
Grade D
Low evidence: expert consensus or could not be verified against literature
No trials of calf muscle energy technique in plantar fasciitis. Calf and plantar fascia stretching is part of first-line care.

Rationale

Calf muscle energy technique to ease gastrocnemius-soleus tightness that limits ankle dorsiflexion.

How it's done, cautions & evidence

How it's done

The calf is taken to its barrier by dorsiflexing the ankle. The patient pushes the foot gently down, at about 10–20% effort, against resistance for 5–10 seconds, relaxes for 3–5 seconds, and the new barrier is taken up.

Cautions

Not used with an acute fracture, a joint infection or a bone malignancy; take care with severe osteoporosis or after surgery that limits muscle contraction. Use the least force needed: too much can tear a muscle or pull off a tendon, especially in older patients.

Evidence in Plantar Fasciitis

Searched 25 Oct 2026: no trials. Indirect: StatPearls (Plantar Heel Pain): gastrocnemius/soleus and plantar fascia stretching may relieve pain between 1 week and 4 months.
