Does low-level laser therapy (LLLT) work for neck pain?
Low-Level Laser Therapy (LLLT) for treating neck pain has been subject to some considerable debate in recent years, with arguments over the validity and scope of meta-analyses and reviews by the American Pain Society and the American College of Physicians (2007), the Cochrane Society (2008), and Chow, et al (2009).
How effective is LLLT for neck pain?
A systematic review of 16 RCTs showed that LLLT reduces pain from immediate post-treatment in acute neck pain and up to 22 weeks following completion of treatment in those with chronic neck pain [ 41 ]. However, the clinical heterogeneity of the pooled trials in this review by Chow and colleagues was debated due to varied dosage [ 41 ].
Does low level laser therapy work for non-specific back pain?
Low-back pain (LBP) is a major health problem and a major cause of medical expenses and disablement. Low level laser therapy (LLLT) can be used to treat musculoskeletal disorders such as back pain. To assess the effects of LLLT in patients with non-specific LBP.
What is LLLT laser therapy?
Lasers used therapeutically emit relatively low light energy [from a few milliwatts (mW) to 100 to 200 mW] for short periods of time (seconds to minutes) and produces insignificant changes in tissue temperature (measured to be around 1.0 °C). As such, this type of laser is often referred to as LLLT or photomodulation.
What is the optimal range of wavelengths used for laser therapy?
Wavelengths in the range 600–700 nm are used to treat superficial tissue, and longer wavelengths in the range 780–950 nm, which penetrate further, are used to treat deeper-seated tissues. Wavelengths in the range 700–770 nm have been found to have limited biochemical activity and are therefore not used.

In patients with long-term low back pain, combining LLLT with exercise has been found to be more beneficial in reducing pain than exercise alone.
What is low level laser therapy?
Various treatment strategies including low level laser therapy (LLLT) are used to treat neck pain [ 6, 7 ]. The term Laser is an acronym for light amplification by stimulated emission of radiation -a form of photonic therapythat is defined by the following characteristics: collimation – it has little beam divergence over distance; convergence – the light waves are all in phase; and monochromicity – it has a single or narrow band of a particular wavelength of light [ 8 ]. Proponents of LLLT note laser devices are either high power or low power. High power laser devices, having a thermal effect, destroy tissue and are used during surgical procedures and for thermolysis. Low power laser devices have little to no thermal effects, have a stimulative effect on target tissues and are used to treat an array of musculoskeletal conditions to decrease pain and inflammation, stimulate collagen metabolism and wound healing, and promote fracture healing [ 8 - 10 ].
What is neck pain?
Neck pain can be classified as simple "non-specific" neck pain (i.e. sprain/strain) described as pain without specific identifiable etiology and “specific” neck pain with identifiable etiology (i.e. radiculopathy) [ 1, 2 ]. According to the Bone and Joint Decade 2000–2010 Task Force, the incidence of neck pain was 150 to 200 per 1000 cases per year, the annual worldwide prevalence varied from 12.1% to 71.5% and neck pain limiting activities was 11.5% [ 3, 4 ]. Neck pain is costly to the patient and society. In Quebec, annual prevalence of neck pain in the working population is close to 43% in men and 54% in women [ 5 ]. Disabling neck pain is in 10% of men and 18% of women in this population. Over 11% of Ontario workers claimed lost-time benefits due to neck pain [ 6 ].

Why do dentists use cold lasers?
Dentists, for instance, rely on the cold laser to treat inflamed oral tissue and heal ulcerations. The cold laser is beneficial for skin rejuvenation and dermatological conditions, such as acne, psoriasis and burns. It might also be used to treat wounds that heal with difficulty, as it happens in case of diabetes.
How does LLLT work?
The laser device is held over the area to be treated, against the skin, and the low-level lasers emit penetrating light in the visible red and near infra-red spectrum (380/400nm-1000nm) deep into the tissues. The energy is absorbed in the tissues and converted into biochemical energy, thus stimulating the activity of the cells in the damaged area. Many patients find that LLLT reduces the inflammation associated with their neck pain and that pain itself is then reduced. Some patients require a number of sessions to effect changes in the body, particularly if their condition is firmly entrenched and involves extensive tissue damage or cervical disc herniation.
What is Low-Level Laser Therapy?
LLLT is a non-invasive single wavelength light treatment that emits no heat, sound, or vibration but is thought to stimulate the cells in the body to promote tissue repair, act as an anti-inflammatory and affect the activity of fibroblasts in areas of damage and trauma.
Is LLLT more effective than surgery?
Treatments are considerably more cost-effective than both surgery and conventional therapeutic strategies (including medication) for chronic neck pain, and have the advantage of inducing no adverse events, on record, or causing permanent and irreversible structural changes to the body. Patients with neck and shoulder pain due to fibromyalgia, strain, disc herniation and spinal stenosis have all benefited from LLLT in research trials and in clinics, although the quality of evidence is questionable in a number of cases making treatment decisions difficult for patient and doctor alike.
Is low level laser therapy effective for neck pain?
Low-Level Laser Therapy (LLLT) for treating neck pain has been subject to some considerable debate in recent years, with arguments over the validity and scope of meta-analyses and reviews by the American Pain Society and the American College of Physicians (2007), the Cochrane Society (2008), and Chow, et al (2009). The first two reports state inconclusive evidence supporting the use of LLLT for lower back pain, whereas the latter review by Chow supports LLLT’s efficacy for treating acute neck pain. Chow’s review in itself has now become the subject of hot debate in the scientific community, highlighting issues with scientific rigour and consensus. The debate also demonstrates the importance of understanding the underlying cause of pain prior to assessing efficacy of treatment rather than treating back and neck pain, both acute and chronic as all part of the same condition.
