Cold Laser Therapy for Plantar Fasciitis
Cold Laser Therapy for Plantar Fasciitis
Evidence-based photobiomodulation for heel pain — 18 randomised controlled trials, no needles, no medication
Who gets plantar fasciitis?
Plantar fasciitis is one of the most common causes of heel pain in Australia. It affects runners and weekend athletes, office workers in unsupportive shoes, tradies on concrete, and retirees whose daily walks have become painful. The common factor is repetitive load on the plantar fascia – the thick band of tissue along the sole of your foot.

How Photobiomodulation May Help Plantar Fasciitis
Why plantar fasciitis can be slow to settle
The plantar fascia is a dense connective tissue that can become irritated and painful when subjected to repetitive overload. Unlike muscles, the plantar fascia has a relatively limited blood supply, which may contribute to slower healing.
What the research suggests may occur with PBM
- Pain reduction — A meta-analysis of 18 RCTs found that LLLT significantly reduced pain at the end of treatment (13.15 mm VAS, 95% CI 7.82–18.48) and at follow-up 4–12 weeks later
- Sustained relief — A separate meta-analysis found that pain relief may persist for up to 3 months after treatment
- Enhanced exercise outcomes — When combined with exercise, PBM produced greater pain reductions (18.15 mm VAS) than exercise alone
- No adverse events — No adverse events were reported across any of the included trials
How it works at a cellular level
Photobiomodulation delivers specific wavelengths of light energy into the plantar fascia and surrounding tissues. At the cellular level, this energy is absorbed by chromophores in the mitochondria, which may enhance cellular metabolism and modulate the inflammatory response in the affected tissue.
Individual responses to photobiomodulation vary. The strongest evidence supports its use alongside exercise and standard care rather than as a standalone treatment. A thorough clinical assessment is recommended before commencing any treatment plan.
The Evidence Base
18 RCTs analysed across multiple systematic reviews, published in BMJ Open, Medicine and Lasers in Medical Science
Naterstad et al. 2022 — BMJ Open Meta-Analysis (18 RCTs)
The most comprehensive analysis of cold laser therapy for lower extremity tendinopathy and plantar fasciitis. Eighteen randomised controlled trials were included, comparing LLLT to placebo, other interventions and as an add-on treatment. Pain was significantly reduced at the end of therapy (13.15 mm VAS, 95% CI 7.82–18.48) and sustained at 4–12 weeks follow-up (12.56 mm VAS, 95% CI 5.69–19.42). As an add-on to exercise, the recommended doses produced even greater pain reductions (18.15 mm VAS, 95% CI 10.55–25.76). No adverse events were reported.

Wang et al. 2019 — Medicine Meta-Analysis (6 RCTs)
This analysis found that LLLT significantly reduced VAS pain scores compared to control groups at the end of treatment. Notably, improvement was sustained for up to 3 months post-treatment — suggesting that the benefits of photobiomodulation may extend well beyond the treatment period itself.

Cinar et al. 2018 — Lasers in Medical Science RCT (49 participants)
This double-arm randomised controlled trial compared LLLT plus usual care (exercise and orthotic support) against usual care alone. The LLLT group showed sustained improvement in foot and ankle function scores and significantly lower pain at 3 months (p=0.03). The 850 nm wavelength used in this trial is within the range of our Multi-Radiance MR5 device.

What to Expect
Your first visit ($99)
- Assessment — Dr Sam Johnson (Chiropractor) will assess your foot and ankle, including the plantar fascia, calf flexibility, foot biomechanics and walking pattern. This helps determine whether photobiomodulation is appropriate for your presentation.
- Treatment — The Multi-Radiance MR5 ACTIV PRO (ARTG-listed, 370913) is applied to the plantar fascia and surrounding tissues. Treatment is painless — most people feel gentle warmth or nothing at all. A typical session for plantar fasciitis takes approximately 10 minutes.
- Your plan — Based on the assessment, Dr Johnson will discuss whether a course of treatment may be appropriate and what complementary approaches (stretching, footwear modification, load management) may support your recovery. No lock-in plans. The decision is always yours.
Ongoing care
- Ongoing care options are discussed at your initial consultation
- Treatment sessions are typically around 10 minutes including setup
- Research protocols showing positive outcomes used multiple sessions per week
- Pain reduction was sustained at 4–12 weeks follow-up and up to 3 months in some studies
- On the Marion Road commuter corridor — convenient before or after work from Plympton Park, Plympton, Park Holme, Glenelg North, Morphettville, Edwardstown, Ascot Park, and Marion
Treatment frequency and duration are individualised based on your clinical presentation and response. The figures above reflect protocols used in published research studies.
⚠️ When to See Your GP Urgently
While plantar fasciitis is common and generally manageable, certain symptoms warrant prompt medical attention:
- Sudden, severe heel pain after a pop or snap — may indicate plantar fascia rupture requiring urgent assessment
- Heel pain with fever, redness and warmth — may indicate infection requiring urgent treatment
- Numbness or tingling in the foot — may indicate nerve involvement requiring investigation
- Heel pain that wakes you at night and is not related to position — may warrant further investigation to rule out other conditions
- Unexplained weight loss combined with persistent foot pain — while rare, these symptoms require investigation
These symptoms require medical assessment beyond the scope of cold laser therapy. If you are unsure whether your symptoms are urgent, please contact your GP or call 13 HEALTH (13 43 25 84) for advice.
Frequently Asked Questions
Why does my heel hurt first thing in the morning?
During sleep, the plantar fascia contracts to a shortened position. When you take your first steps, the fascia is suddenly stretched under your full body weight. This creates the characteristic sharp pain that many people describe. The pain often eases after a few minutes of walking as the tissue warms up and lengthens. If this pattern sounds familiar, it is one of the most recognisable signs of plantar fasciitis.
Should I stop running?
Complete rest is rarely the answer and can sometimes make things worse by allowing the tissue to decondition further. The key is load management — finding the right balance between staying active and not overloading the fascia. Research suggests that photobiomodulation combined with appropriate exercise produces better outcomes than either approach alone. We can help you modify your training load rather than abandoning it.
Will orthotics help?
Orthotics can play a role in managing plantar fasciitis by redistributing load across the foot. However, they address biomechanics rather than the tissue itself. Photobiomodulation works at the cellular level and may complement orthotic use. During your assessment, we can discuss whether orthotics may be helpful alongside cold laser therapy.
How much does treatment cost at Adelaide Cold Laser?
Your first visit is $99, which includes a thorough assessment and treatment where clinically appropriate. Ongoing care options are discussed at your initial consultation. Most private health funds cover part of the cost under chiropractic extras. No lock-in plans. If you prepay for sessions you do not end up using, we refund them in full. The decision is always yours.
I have already tried cortisone injections — will cold laser be any different?
Photobiomodulation works through a completely different mechanism. Cortisone injections suppress local inflammation temporarily, whereas cold laser therapy delivers light energy that may influence cellular metabolism and tissue repair processes. The two approaches are not mutually exclusive. Some patients explore photobiomodulation when they prefer to avoid repeat injections or when injection relief has been short-lived. Individual responses vary.
How long until I notice a difference?
The research suggests that pain reduction from photobiomodulation is typically observed over a course of treatment rather than after a single session. The largest meta-analysis found that pain was significantly reduced at the end of treatment and sustained at 4–12 weeks follow-up. Some people notice improvement within the first few sessions; others take longer. During your assessment, Dr Sam Johnson (Chiropractor) will discuss realistic expectations based on your presentation.
What is the evidence for cold laser therapy for plantar fasciitis?
The evidence base is strong. An 18-study meta-analysis published in BMJ Open (2022) found significant pain reductions both at the end of treatment and at follow-up. A separate analysis in Medicine (2019) found pain relief sustained for up to 3 months. An RCT in Lasers in Medical Science (2018) found that laser plus usual care outperformed usual care alone for function and pain at 3 months. No adverse events were reported across any included trials.
Is this the same as those laser devices you can buy online?
No. Consumer laser devices typically deliver far lower energy levels than clinical-grade equipment. The Multi-Radiance MR5 ACTIV PRO is an ARTG-listed (370913) medical device that delivers super-pulsed laser at 905 nm alongside 875 nm infrared and 640 nm red light. The clinical trials supporting photobiomodulation for plantar fasciitis used devices with specific power and wavelength characteristics — consumer products generally do not meet these parameters.
Is my plantar fasciitis caused by flat feet?
Flat feet (pes planus) can be a contributing factor, but plantar fasciitis occurs in people with all foot types. Overpronation, high arches, tight calves, sudden increases in activity, and time spent on hard surfaces are all recognised contributors. An assessment can help identify what factors may be relevant to your situation specifically.
Can plantar fasciitis come back after treatment?
Recurrence is possible, particularly if the underlying contributing factors are not addressed. This is why a comprehensive approach — addressing load, footwear, flexibility and biomechanics alongside photobiomodulation — typically produces better long-term outcomes than any single treatment in isolation.
