Plantar fasciitis
back to main page
Plantar fasciitis is one of the most common causes of plantar heel pain. The plantar fascia is a strong band of connective tissue running from the calcaneal tuberosity to the bases of the toes that supports the longitudinal arch of the foot, stores elastic energy, and stabilizes the foot during gait. Despite its established name, the chronic form of the condition is typically degenerative and overload-related in nature, with features of active inflammation playing a minor role. A more accurate term in such cases is plantar fasciopathy. The foundation of management includes identifying overloading factors, temporary activity modification, and physical therapy encompassing stretching, progressive strengthening, and improving lower extremity biomechanics. Most patients regain function through conservative treatment, although remodeling of the fascia can take many months.
Plantar fasciitis - where does it come from
The plantar fascia is a component of the foot's support mechanism. During weight-bearing, it undergoes controlled tension, and as the heel rises, it winds around the metatarsal heads. This phenomenon, referred to as the windlass mechanism, stiffens the arch of the foot and prepares it for push-off. Repetitive loading exceeding the tissue's capacity to regenerate leads to micro-damage, disruption of collagen fiber organization, and local thickening of the fascia, most commonly at its medial attachment to the calcaneus.
Overload can occur after a sudden increase in step count, running intensity, uphill running, or jumping exercises. Prolonged standing work, hard surfaces, footwear with insufficient cushioning, and a rapid change in the type of footwear used are also significant.
The development of symptoms may be favored by:
- limited ankle dorsiflexion, often associated with tightness of the gastrocnemius or soleus muscle;
- weakness of the intrinsic foot muscles and calf muscles;
- impaired movement control of the hip, knee, and foot;
- excessive pronation or a foot with a high, rigid arch;
- increased body weight, especially in individuals with low physical activity;
- a decline in tissue regenerative capacity with age;
- running-related overload and limited adaptation time to training.
A heel spur visible on an X-ray represents a bony reaction to prolonged stress on the heel region. Its presence correlates poorly with pain intensity. It is also found in many asymptomatic individuals; therefore, the spur itself does not determine the diagnosis or the need for interventional treatment.
Plantar fasciitis - how the pain manifests
The most characteristic feature is pain in the medial plantar aspect of the heel, strongest during the first steps after waking up or after prolonged sitting. After a short period of walking, the discomfort often subsides, and then increases with prolonged standing, walking, or running. The pain can be sharp, burning, or deep and localized. In some patients, it also involves the medial border of the foot arch.
Clinical examination typically reveals:
- tenderness at the medial tubercle of the calcaneus;
- reproduction of pain during passive dorsiflexion of the great toe;
- limited ankle dorsiflexion;
- worsening of symptoms while standing on tiptoes or weight-bearing on one limb;
- gait pattern abnormalities resulting from reflex heel unloading.
Diagnosis is usually based on medical history and functional examination. Imaging studies are primarily used to evaluate cases with an atypical course, after trauma, or resistant to properly managed therapy. Ultrasonography may show thickening of the fascia, decreased echogenicity, and changes near the insertion. Magnetic resonance imaging helps assess soft tissues and rule out, among others, a stress fracture, fascial injury, or a proliferative process.
Heel pain requires differentiation from heel fat pad syndrome, nerve branch entrapment, tarsal tunnel syndrome, Achilles tendinopathy, calcaneal stress fracture, and referred pain from the spine. Bilateral symptoms accompanied by morning stiffness may occur in the course of inflammatory rheumatic diseases.
Plantar fasciitis - who is at risk
The peak incidence usually occurs in middle age, but the problem also affects younger athletes and people who work in a standing position. A particular group consists of runners, dancers, indoor sports athletes, and individuals starting intensive training after a period of low activity.
The risk increases when several factors occur simultaneously:
- a sudden increase in training volume or daily step count;
- limited ankle joint mobility;
- low strength and endurance of the calf and foot muscles;
- prolonged standing on hard surfaces;
- obesity or rapid weight gain;
- ill-fitting, worn-out, or very hard footwear;
- impaired sensation and foot biomechanics associated with diabetes;
- the perimenopausal period and age-related changes in connective tissue properties.
The shape of the foot alone is rarely a sufficient explanation for the condition. Clinical significance lies in the combination of anatomical structure, loading patterns, muscular capacity, and the tissues' ability to regenerate. Therefore, the assessment should include the entire lower limb, gait pattern, ankle mobility, and tolerance to daily and sports loads.
Prevention involves gradually increasing activity, maintaining adequate muscle strength, and ensuring recovery tailored to the workload. In individuals who are overweight, gradual weight reduction can reduce the mechanical stress acting on the foot.
Plantar fasciitis - exercises
Exercises are a fundamental element of treatment and should be tailored to tissue pain reactivity. Activity may cause mild discomfort, provided that symptoms return to baseline within 24 hours. A marked increase in pain the following morning indicates the need to reduce the number of repetitions, range of motion, or additional load.
The following program is most commonly used:
- Plantar fascia stretching: in a seated position, place the painful foot across the opposite leg and gently pull the toes back toward the shin until tension appears in the arch. The position is held for about 20–30 seconds and repeated several times, especially before taking the first steps in the morning.
- Gastrocnemius stretching: standing facing a wall, keep the exercised limb behind with the knee straight and the heel on the ground.
- Soleus stretching: performed similarly, but with the knee of the rear limb slightly bent.
- Calf raises: initially with both legs, then single-leg. Slowly raising and lowering the heel strengthens the calf muscle complex and increases the tissues' capacity to bear loads.
- Calf raises with toes on a rolled towel: elevating the toes increases tension on the fascia, and controlled raises provide it with a progressive mechanical stimulus.
- Short foot exercise: involves gently drawing the head of the first metatarsal bone toward the heel without curling the toes. It activates the muscles supporting the arch.
- Balance exercises: standing on one leg and more complex stabilization tasks improve control of the foot and the entire lower limb.
A ball or chilled roller may briefly reduce pain perception, but intensive rolling directly over the very tender insertion may increase irritation. Treatment is complemented by manual therapy, temporary foot taping, individually fitted insoles used together with exercises, and a night splint for individuals with persistent first-step pain.
In the Ambasada Urody offer, the issue in question is primarily related to physiotherapy and manual therapy, manual therapy according to the Maitland concept, and manual therapy. These may include functional diagnostics, soft tissue work, mobilization of the foot and ankle joints, and the selection of exercises. The available acoustic wave is used in the offer mainly for aesthetic body treatments. Treatment of the fascia requires equipment, parameters, and qualifications specific to extracorporeal shock wave therapy in musculoskeletal conditions, which is why the possibility of such an application should be confirmed during a consultation.
Plantar fasciitis - when to see a doctor
Consultation with a doctor, physiotherapist, or orthopedist is recommended when pain hinders normal walking, persists despite several weeks of proper load modification, or recurs regularly. Early assessment helps confirm the diagnosis and identify factors sustaining the overload.
Urgent diagnostics are required for:
- sudden pain following an injury, accompanied by a popping sound or an inability to bear weight on the foot;
- rapidly increasing swelling, redness, warmth of the skin, or fever;
- resting or night pain that progressively increases;
- numbness, burning sensation, sensory disturbances, or muscle weakness;
- a non-healing wound, ulceration, or discoloration of the foot;
- pain after an increase in activity in an individual with osteoporosis or a suspected stress fracture;
- bilateral heel pain co-occurring with back pain, psoriasis, eye inflammation, or chronic morning stiffness;
- unexplained weight loss, a medical history of cancer, or a general deterioration in health.
Treatment usually begins with education, load adjustment, physiotherapy, and an exercise program. Painkillers are selected by a doctor, taking comorbidities into account. Glucocorticosteroid injections can provide short-term relief, but carry the risk of fat pad atrophy and fascia damage. Extracorporeal shock wave therapy is considered primarily for chronic symptoms resistant to basic treatment. Surgical intervention remains a solution for carefully selected cases in which months of comprehensive conservative therapy have failed to restore acceptable function.
