Heel pain can be a real drag, especially when it limits your ability to walk, run, or simply stand for long periods. Plantar fasciopathy, previously known as plantar fasciitis, is a common culprit behind this discomfort. This blog post will shed light on plantar fasciopathy, including its risk factors, diagnosis, and the biomechanics involved.
What is Plantar Fasciopathy?
The plantar fascia is a thick band of tissue that runs along the bottom of your foot, connecting your heel bone to your toes. It acts like a spring, supporting the arch of your foot and absorbing shock during activities like walking and running. Plantar fasciopathy occurs when this tissue becomes overloaded and undergoes degeneration, leading to pain and inflammation.
Who is at Risk?
While anyone can develop plantar fasciopathy, certain factors increase your risk:
- Age: The condition is more common between the ages of 40 and 60.
- Activity level: Both athletes and non-athletes can be affected, although runners have a higher risk (perhaps due to changes in training loads after a period of illness or some reason for time off).
- Being overweight or obese: Excess weight does put extra stress on the plantar fascia, but may also support more inflammatory changes.
- Certain activities: Occupations that involve prolonged standing or walking can contribute to the problem.
- Changing activities: when starting a new exercise regime or moving from a predominantly sitting to standing job, the change in workload through the lower legs can impact the plantar fascia.
- Footwear: Poor footwear can impact the stress on the plantar fascia, or more often we see a recent change in footwear that could be more or less supportive. It is often the change that is the issue!
Diagnosis:
Your physiotherapist will typically diagnose plantar fasciopathy based on your symptoms and a physical examination. In some cases, imaging tests like ultrasound may be used to confirm the diagnosis and rule out other causes of heel pain.
Understanding the Biomechanics:
The way your foot functions plays a crucial role in plantar fasciopathy. Here are some key points to consider:
- The Windlass Mechanism: This mechanism describes how the plantar fascia tightness and supports the foot arch during weight-bearing activities. Tightness or weakness in certain muscles can disrupt this mechanism and increase stress on the plantar fascia.
- Gait Cycle: Plantar fascial tension increases during specific phases of the gait cycle, particularly during heel strike and toe-off.
