Summus Horizon Medical Laser

Doctors Crown and Katherine Hoffman at Southeast Chiropractic: The Motion Centers, Gastonia are excited to offer state-of-the-art Cold Laser Therapy to Gaston County.  

The Summus Horizon Class IV Cold laser is a quantum leap in laser technology and has been designed and engineered using decades of sophisticated research and technology.


Proven to biostimulate tissue repair and growth, Class IV laser therapy is a non-surgical, drug-free treatment option designed to treat acute to chronic pain.

Specific red and near-infrared wavelengths induce a therapeutic effect within the body. Laser energy stimulates the healing process by accelerating blood flow, bringing water and other nutrients to the affected area.

Laser therapy benefits include:

  • Increased circulation
  • Decreased swelling
  • Reduced pain
  • Enhanced tissue repair

Throughout treatment, metabolic activity stimulates at the cellular level, improving the transport of vital nutrients across the cell membrane, which increases the production of cellular energy (ATP). 

This scientifically proven treatment method is used to decrease inflammation and the formation of scar tissue.

Treatment with the Summus Medical laser is comfortable and safe.  

After evaluation to see if you are a candidate for laser therapy, your treatment will be scheduled and will begin as soon as possible.  

Treatment times vary from 6-30 minutes and you can continue with normal activities both before and after treatment.  We may ask you to bring loose-fitting clothing or wear a gown to allow access to tissues in need of cold laser therapy.

  • Knee pains /injuries:
    ACL/PCL injuries, arthritis, baker’s cyst, meniscus and ligament injuries, Osgood-Schlatter’s, post-surgical repair, sports injuries.
  • Neuropathy


Photobiomodulation (PBM) is the application of red and near-infra-red light over injuries or lesions to improve wound and soft tissue healing, reduce inflammation and give relief for both acute and chronic pain.


The Summus Horizon Medical laser works by targeting four specific structures within the targeted tissues.  These tissues are target simultaneously, utilizing four different wavelengths of laser light.

  • 650 nanometers:  Targets Superficial receptors to accelerate tissue healing, increase cellular regeneration, reduce the need of antibiotics, and drastically shorten healing time.
  • 810 nanometers: Targets Mitochondria, the energy powerhouse of the cell.  This drastically increases the conversion of O2 to ATP (the energy currency of the cell), accelerates cellular metabolism, stimulates the immune system, and penetrates deep within the target tissue.
  •  915 nanometers:  Targets Hemoglobin, the oxygen-carrying molecule in the body.  This serves to double Oxygen delivery to the target tissue, improves pain relief, and enhances healing effects.
  • 980 nanometers:  Targets Water in the blood which improves circulation, increases pain relief, decreases morbidity, and encourages faster recovery.

This technology has been in use in clinical practice for over a decade and with the introduction of the Summus Horizon Medical Laser, we are now able to see significant and fast results for a variety of acute and chronic issues.

Peripheral neuropathy is a general term for a series of disorders that result from damage to the peripheral nervous system. Peripheral neuropathy can affect multiple nerves (polyneuropathy) or single nerves (mononeuropathy). Mononeuropathy is usually damage to a single nerve or nerve group by trauma, injury, local compression, prolonged pressure, or inflammation. Examples include carpal tunnel syndrome and Bell’s Palsy.[i]

Polyneuropathies are more common, and are caused by diabetes, chemotherapy, toxic chemical exposure, chronic alcoholism, certain medications and more[ii]. This article will focus on lower extremity peripheral neuropathy caused by diabetes and chemotherapy, and how photobiomodulation (PBM, commonly known as laser therapy) with a class 4 therapeutic laser is a safe, non-invasive yet very effective treatment solution.

 Peripheral neuropathy (PN) is a polyneuropathy caused by diabetes, chemotherapy, toxic chemical exposure, chronic alcoholism, certain medications and more[iii]. Medical treatments for neuropathy include opioid pain medications which have high potential for addiction and abuse. Photobiomodulation (PBM, also known as laser therapy) with a class 4 therapeutic laser is a non-invasive, safe and very effective treatment solution for PN.

The number of people with diabetes worldwide is predicted to double between 2000 and 2030, approaching a pandemic level of 366 million people. Diabetic peripheral neuropathy has a lifetime prevalence of approximately 50% and is a leading cause for disability due to foot ulceration and amputation, gait disturbance, and fall-related injury. Roughly 30% of patients suffer from neuropathic pain.[iv]

In 2015, roughly 30.3 million people, or 9.4% of the US population suffer from diabetes, with about one-fourth of those being undiagnosed. Average medical expenditures for people with diagnosed diabetes were about $13,700 per year.[v] Diabetic peripheral neuropathy signs and symptoms include numbness, loss of temperature sensation, tingling or burning, and more.[vi]

Chemotherapy-induced peripheral neuropathy (CIPN) is a common side-effect of anti-neoplastic pharmaceuticals. It typically manifests as numbness, paresthesia, pain, and/or burning. Motor dysfunction and/or autonomic dysfunction can also occur. The prevalence of CIPN after chemotherapy is 20–51%, but estimates vary considerably depending on the severity threshold and mechanism of detection. Underreporting of both the prevalence and magnitude of CIPN is likely because sensory symptoms are not always apparent.[vii]

In vitro and in vivo animal experiments show that PBM with infrared laser light can modulate neuropathic pain by altering chronic inflammation, decreasing mechanical allodynia, suppressing conduction velocity and reducing amplitude of action potentials.[viii] Further animal experiments show that PBM-induced anti-nociception comes from the release of central opioids, helping with pain relief in the early stages of treatment. Later stages of PBM treatment appear to be inducing permanent neuroplastic changes that maintain the antinociceptive state, without depending on opioid release in the periphery.[ix]

The general mechanisms of action for PBM are numerous, and involve intra- and extracellular effects, as well as effects on the cell membrane[x]. Some include the following: absorption of laser photons by water molecules to enhance microcirculation, disassociation of inhibitory nitric oxide from the cytochrome-c oxidase enzyme, activation of light-sensitive ion channels and activation of transcription factors.[xi] The primary effects of PBM occur when there is direct photonic absorption by chromophores in the tissues[xii]. Class 4 therapeutic lasers are FDA-cleared prescription medical devices that can deliver photons of red and infrared laser light to the large volume of tissue required for treatment of peripheral neuropathy.

One study assessed the safety and efficacy of class 4 laser therapy on pain management,functionality, systemic inflammation, and overall quality of life of patients with diabetic peripheral neuropathy. PBM treatment was delivered to the lumbar region and the plantar surface of the foot, using power levels from 2 to 8 watts. No adverse events were reported during the study period. After the 12-week intervention, pain levels were significantly lower, Timed Up and Go test times (assessing functionality) were significantly improved, and serum levels of IL-6 and MCP-1 were decreased significantly.[xiii]

Another study investigated PBM via class 4 laser therapy for chemotherapy-induced peripheral neuropathy (CIPN). This randomized, double-blinded, sham-controlled, cross-over trial concluded, “Among patients with CIPN, PBM produced significant reduction in neuropathy symptoms.” PBM treatment was delivered to the lumbar region and lower extremity, with power settings from 6.75 to 12 watts, using a combination of continuous wave and pulse frequencies up to 20,000Hz. Treatment times were 30 minutes, and there were no adverse events involving active treatment. The modified total neuropathy score (mTNS), a validated tool that assesses six domains of sensory and motor neuropathy, was used as the outcome measure. The study found that, “photobiomodulation is an effective, low-toxicity treatment for CIPN. Nearly 90% of patients experience significant improvement in mTNS scores that begins within weeks of initiating treatment and persists for at least 10 weeks after the conclusion of therapy. The benefits appear to accrue similarly to patients with variable duration and intensity of neuropathy symptoms, as well as to patients with variable chemotherapy exposures.”[xiv]

In conclusion, peripheral neuropathy is a serious problem regardless of the cause. Standard medical treatments have associated side effects and only mask the symptoms.  Class 4 laser therapy treatments can deliver symptomatic relief and show great promise in the ability to restore nerve function to the patient suffering from peripheral neuropathy.
