Struggling with Heel Pain? Laser Therapy for Plantar Fasciitis

Laser Therapy for Plantar Fasciitis

That sharp, stabbing pain in your heel during your first steps in the morning isn't just "soreness"—it’s likely Plantar Fasciitis. Affecting up to 15% of adults, this stubborn condition occurs when repetitive micro-tears lead to structural degeneration of the fascia.

At ReWin Therapy, we see many patients who have tried stretching, ice, and rest with no luck. Because this condition is more degenerative than inflammatory, traditional "cold" treatments often fail to reach the root of the problem.

What makes plantar fasciitis difficult to treat?

Plantar fasciitis begins with micro-tears near the medial calcaneus, which leads to heel pain after your first steps in the morning or with prolonged standing. This is often seen in athletes, military personnel, sedentary individuals, or those with poor foot biomechanics. Some of the other issues seen with plantar fasciitis include.

  • Reduced blood flow to the plantar fascia
  • Structural collagen disorganisation
  • Mechanical overload
  • Persistent morning stiffness

Because it is more degenerative than inflammatory, standard treatments such as anti-inflammatories, ice, and rest may not be enough.

What is High Intensity Laser Therapy (HILT)?

High Intensity Laser Therapy uses wavelengths of infrared light to stimulate photobiomodulation (PBM). This is a process where light energy helps to stimulate tissue repair. This is very different from “cold” or low-level lasers.

The Lightforce XLi used at ReWin Therapy uses up to 40 watts of continuous power. This is much higher than standard lasers which allows for deeper penetration and faster treatment times. This device uses dual wavelengths, the 810nm and 980nm.

810nm: boosts ATP, improves cellular energy and nitric oxide levels.

980nm: reduces pain and inflammation.

Why the Lightforce XLi is ideal for Plantar Fasciitis

The Lightforce XLi stands out because of its:

  • 40W continuous power output (deeper penetration)
  • Dual wavelength system
  • Ability to treat large areas quickly
  • On-skin contact heads for increased comfort and dose efficiency

For the plantar fascia specifically, this level of penetration is important. The fascia is a dense and fibrous tissue which requires high doses of PBM to stimulate tissue regeneration.

Laser therapy aims to support healing using the following mechanisms.

  • Collagen remodelling
  • Reduced inflammation
  • Improved vascularity
  • Accelerated cell repair
  • Improved tendon and fascia metabolism

This helps to address the root causes of plantar fasciitis, not just the symptoms.

What to expect at ReWin Therapy?

At ReWin Therapy, our interventions for plantar fasciitis include:

  • Calf and foot muscle strengthening
  • Mobility and gait retraining
  • Load modification for sport and work
  • Lifestyle changes around sleep, weight, and activity levels

A typical session will involve:

  • A full assessment of gait and foot mechanics
  • 4-7 minutes of high intensity laser applied directly to the fascia
  • A tailored home exercise program
  • Follow-up every 1-2 weeks depending on severity

Final Thoughts

Plantar fasciitis can be painful and stubborn to treat. But modern medicine has technology that can help to speed up healing at a cellular level, whilst exercise and lifestyle changes can assist with achieving long term results.

If you’ve been struggling with persistent heel pain, HILT might be the breakthrough to help you get moving again.
