Plantar Fasciitis and Physiotherapy

Introduction

Plantar fasciitis is one of the most common causes of heel pain, affecting people of all ages, especially those who are active or spend long hours on their feet. It occurs when the plantar fascia, a thick band of tissue that runs along the bottom of your foot, becomes inflamed. This condition can be both painful and debilitating, often making walking and standing difficult.

Fortunately, physiotherapy plays a key role in the treatment and rehabilitation of plantar fasciitis. This booklet provides essential information about plantar fasciitis, its causes, symptoms, and how physiotherapy can help alleviate pain, improve function, and prevent future recurrences.

What is Plantar Fasciitis?

Plantar fasciitis is an inflammation of the plantar fascia, the connective tissue that extends from your heel to the toes. The plantar fascia helps support the arch of your foot and absorbs shock when you walk or run.

In plantar fasciitis, repetitive stress and strain on the plantar fascia cause small tears or irritation, leading to inflammation and pain, particularly in the heel area. The condition is most commonly associated with intense physical activity, improper footwear, and certain medical conditions.

Causes and Risk Factors

The exact cause of plantar fasciitis is not always clear, but several factors may increase the likelihood of developing the condition:

1. Overuse or Repetitive Strain:

●     Activities that involve excessive walking, running, or standing, especially on hard surfaces, can put extra strain on the plantar fascia, leading to inflammation and pain.

2. Foot Structure:

●     Individuals with flat feet, high arches, or an abnormal walking pattern may be at higher risk of plantar fasciitis due to increased stress on the foot’s structures.

3. Age:

●     Plantar fasciitis is more common in individuals between the ages of 40 and 60, as the plantar fascia loses some of its elasticity and strength with age.

4. Weight:

●     Being overweight or obese can increase pressure on the feet, especially the heel, contributing to the development of plantar fasciitis.

5. Tight Calf Muscles or Achilles Tendon:

●     Tightness in the calf muscles or Achilles tendon can affect foot mechanics and increase strain on the plantar fascia, leading to inflammation.

6. Poor Footwear:

●     Wearing shoes that lack arch support, cushioning, or proper fit can contribute to the development of plantar fasciitis by putting undue stress on the feet.

Symptoms of Plantar Fasciitis

The most common symptom of plantar fasciitis is pain in the heel or the bottom of the foot. Other symptoms may include:

●     Sharp Heel Pain: This is usually felt in the morning when taking the first few steps after getting out of bed or after long periods of rest. The pain may subside as you move around but can return after prolonged standing or walking.

●     Stiffness: There may be a feeling of tightness in the bottom of the foot, especially in the morning or after sitting for long periods.

●     Swelling and Tenderness: The heel may be tender to the touch, and swelling may develop in more severe cases.

●     Pain after Exercise: While the pain is often worse in the morning, it can also worsen after exercise, especially high-impact activities like running.

How Physiotherapy Can Help with Plantar Fasciitis

Physiotherapy is a highly effective treatment option for plantar fasciitis. It focuses on relieving pain, improving foot and ankle mechanics, and promoting healing through a combination of manual therapy, exercises, and education. Here’s how physiotherapy can help:

1. Pain Relief Techniques

●     Cold Therapy (Cryotherapy): Applying ice or cold packs to the heel can help reduce inflammation and numb the area to alleviate pain.

●     Heat Therapy: In some cases, heat therapy (e.g., warm packs or warm foot baths) can help relax the foot muscles and improve blood circulation, easing stiffness and discomfort.

●     Electrotherapy: Physiotherapists may use TENS (Transcutaneous Electrical Nerve Stimulation) to manage pain by delivering electrical impulses that interfere with pain signals.

●     Ultrasound Therapy: This involves applying sound waves to the affected area to promote healing by increasing blood flow and reducing inflammation.

2. Stretching and Strengthening Exercises

One of the main goals of physiotherapy for plantar fasciitis is to improve flexibility and strengthen the muscles supporting the foot and ankle. Physiotherapists often prescribe:

●     Plantar Fascia Stretching: Gentle stretches targeting the plantar fascia can help relieve tension and improve flexibility.

○     Example: Sitting down and crossing one leg over the other, gently pulling the toes toward the shin to stretch the bottom of the foot.

●     Calf and Achilles Stretching: Tight calf muscles and Achilles tendons can worsen plantar fasciitis. Stretching these muscles can help reduce the strain on the plantar fascia.

○     Example: Standing with one leg forward, gently bending the knee and pressing the heel of the back leg into the ground.

●     Strengthening Exercises: Strengthening the muscles of the foot, calf, and ankle helps improve support and reduce stress on the plantar fascia.

○     Example: Towel scrunches—place a towel on the floor and use your toes to scrunch it toward you.

○     Example: Heel raises—slowly rising onto your toes to strengthen the calf muscles.

3. Manual Therapy

Physiotherapists may use manual therapy techniques to help mobilize the foot and ankle joints, release tightness, and promote healing. Techniques such as joint mobilizations, massage, or myofascial release may be used to alleviate pain and improve movement in the foot.

4. Footwear Advice and Orthotics

●     Footwear Guidance: Wearing proper footwear is critical in managing plantar fasciitis. Physiotherapists will recommend shoes that provide adequate arch support, cushioning, and a proper fit.

●     Orthotics: Custom-made insoles or orthotics may be recommended to provide additional support and cushioning to the foot, redistribute pressure, and alleviate pain associated with plantar fasciitis.

5. Activity Modification and Education

A physiotherapist will educate you on how to modify activities that may be exacerbating the condition, such as:

●     Avoiding prolonged standing or walking on hard surfaces.

●     Reducing high-impact activities like running and jumping until the foot heals.

●     Incorporating low-impact exercises like swimming or cycling as alternatives.

In addition, physiotherapists will educate you on posture, movement patterns, and proper body mechanics to prevent further strain on the plantar fascia and reduce the risk of recurrence.

What to Expect from Physiotherapy for Plantar Fasciitis

When you visit a physiotherapist for plantar fasciitis, you can expect the following:

●     Comprehensive Assessment: The physiotherapist will evaluate your foot structure, walking pattern, posture, and any contributing factors to determine the cause of the pain.

●     Individualized Treatment Plan: Based on your assessment, the physiotherapist will create a customized treatment plan, which may include a combination of exercises, manual therapy, modalities for pain relief, and education on self-care.

●     Regular Follow-Up: Physiotherapy sessions are typically scheduled weekly or bi-weekly, depending on the severity of the condition. Progress will be monitored, and the treatment plan will be adjusted as needed.

●     Home Exercise Program: Your physiotherapist will provide you with a set of exercises to do at home to supplement in-clinic treatments and accelerate healing.

Additional Treatments for Plantar Fasciitis

In some cases, when physiotherapy alone is not enough to relieve symptoms, additional treatments may be recommended:

●     Corticosteroid Injections: If inflammation is severe, a corticosteroid injection may be used to reduce swelling and pain in the heel.

●     Shockwave Therapy: High-energy shockwaves may be directed at the heel to stimulate healing and reduce pain.

●     Surgery: In rare cases, if conservative treatments fail after several months, surgery may be considered to release the tight plantar fascia or remove damaged tissue.

When to Seek Physiotherapy for Plantar Fasciitis

It’s important to seek physiotherapy treatment as soon as you notice the symptoms of plantar fasciitis. Early intervention can help prevent the condition from worsening and reduce the risk of developing chronic heel pain.

You should consider seeing a physiotherapist if:

●     You experience persistent heel pain, especially in the morning.

●     The pain does not improve with rest or over-the-counter pain relievers.

●     The pain interferes with your daily activities or sports performance.

Conclusion

Plantar fasciitis can be a painful and frustrating condition, but with the right treatment, most individuals can recover and return to their normal activities. Physiotherapy plays a key role in the management of plantar fasciitis by reducing pain, improving foot mechanics, and promoting healing. Through a combination of pain-relief techniques, stretching and strengthening exercises, manual therapy, and education, physiotherapy can help you regain function and prevent future flare-ups.

If you are experiencing symptoms of plantar fasciitis, consult a physiotherapist for an assessment and personalized treatment plan tailored to your needs.
