An introduction to LightForce® Therapy Lasers

Laser therapy is a clinically proven effective adjacent treatment modality in the physical therapy practice intended for the relief of painful muscles and joints associated with acute and chronic tissue injuries1. It is also indicated for helping relieve pain and stiffness associated with osteoarthritis through its ability to increase localized blood flow.2

Although Low Level Laser Therapy (LLLT) devices have been used in physical therapy treatments for decades3, their relative low power means treatment times are excessive and impractical when treating larger areas and/or deeper tissues.

However, High Power Laser (HPL) therapy devices are capable of delivering sufficient power (at a level of Watts compared to the mW output of LLLT devices) to achieve therapeutic dosage without prolonging the application time. This allows treatment of a wider range of indications including deep and large structures within reasonable times, making HPL both an effective and practical physical therapy modality.

LightForce Deep Tissue Therapy Lasers

In the field of therapeutic laser technology, LiteCure® has long been one of the market’s leading manufacturers, with its LightForce® range of products used to deliver an estimated 1.2 million treatments per month in 29 countries around the world. Founded in 2006, the company has recently been acquired by DJO®, a leading global provider of medical technologies. By adding LiteCure to its portfolio, DJO plans to further increase the global presence of LightForce products and make their therapeutic value available to even more clinicians and patients.

All three devices share a set of core features which work together to provide users with safe, user-friendly, and controllable functionality, so that no matter which model they choose they can be assured of a positive and effective user experience.

LightForce Therapy Lasers – three different devices to meet your needs

Customers looking to introduce high power laser therapy into their practice have three different LightForce devices to choose from, each with its own maximum level of power, ranging from 15W to 40W.

All three devices share a set of core features which work together to provide users with safe, user-friendly, and controllable functionality, so that no matter which model they choose they can be assured of a positive and effective user experience.

LightForce® XLi Therapy Laser – 40W

Increased power, for the busiest practices treating the most challenging cases.

Capable of delivering up to 40W of power, the LightForce® XLi is the most powerful device in the range. Its increased power reduces the time needed to apply a therapeutic dose of light energy, and with real-time dosing feedback and the XL Treatment Cone, deeper structures can be treated faster over larger areas, all of which helps clinicians to increase the efficiency of their practice.

LightForce® XPi Therapy Laser – 25W

As above, but with a maximum of 25W of power.

LightForce® FXi Therapy Laser – 15W

A portable unit for practices treating in multiple locations in or out of the office.

At 3.2 kg, the LightForce® FXi is easy to transport, with a rechargeable battery that lasts for up to half a day on a single charge, making it the ideal choice when you need to bring the treatment to the patient. And despite its more compact size and lighter weight, with up to 15W of power it still has the energy to deliver effective laser treatments in short amounts of time.

LightForce devices benefit from the following features:

Empower IQ

LightForce’s Empower IQ delivery system gives the user real-time feedback on treatment speed to help them treat effectively. Each device’s hand-held laser applicator comes equipped with a sensor that tracks its speed during treatment and feeds back to the user via a colour-coded light. As soon as they begin treating too slowly the light changes from green to red to indicate they need to speed up; go too fast and it will turn yellow to tell them to slow down.

Built-in protocols

LightForce products feature in-depth protocol settings that detect which head is in use and recommend the appropriate power level. This helps guide the user in matching applicator heads to power output levels, giving them extra confidence during treatments and reducing learning time.

influence® technology

influence® technology helps guide LightForce users in using the appropriate treatment settings for their patients. Simply enter the patient’s parameters based on condition, skin type, body type, and acuity, and the device will select the correct dose to be administered. These settings can then be saved in preparation for future sessions and adjusted as necessary.

Working from Home and the Potential Strain on our Bodies.

Treating low back pain with electrotherapy

Among the many impacts of the coronavirus pandemic, one of the least publicised is that of low back pain. Far more of us are currently working from home, often without the necessary ergonomic support of chairs and desks designed to prevent back problems, and as a result, physiotherapists are seeing a growing number of patients presenting with low back pain.

Among the many impacts of the coronavirus pandemic, one of the least publicised is that of low back pain. Far more of us are currently working from home, often without the necessary ergonomic support of chairs and desks designed to prevent back problems, and as a result, physiotherapists are seeing a growing number of patients presenting with low back pain.

One way of treating low back pain is with electrotherapy. The practice takes advantage of the high excitability of nerve fibres, stimulating them with electrical pulses to achieve a number of therapeutic effects. As well as pain relief, this includes stimulation to help strengthen muscles, meaning it can be used to address both the symptoms and causes of low back pain.

Treating the SYMPTOMS of low back pain with electrotherapy

Most acute low back pain is a result of injury to the muscles, ligaments, joints, or discs. The body’s reaction to injury is to instigate an inflammatory healing response, which can cause severe pain.

TENS (Transcutaneous Electrical Nerve Stimulation) uses electrical pulses to provide pain relief by blocking pain signals from reaching the brain. High frequency (HF) TENS, or sensory stimulation, uses pulses of 80-100 Hz and works via the gate control mechanism, inhibiting the transmission of pain signals to the brain while producing a pleasant tingling sensation. As a result, HF TENS is effective for providing patients with relief from the symptoms of lumbar pain.1

However, rather than just treat the cause of the pain, it’s important to also address the cause of the injury. Thankfully, electrostimulation also has an answer for this.

Treating the CAUSES of low back pain with electrotherapy

Sitting slumped over a desk while you work puts increased strain on the muscles and ligaments in your back, which can then lead to injury and low back pain. To address the cause of posture-related low back pain, we need to restore balance between the trunk flexors and extensors and strengthen our paraspinal and abdominal muscles to improve spinal stability and help us sit up straight. This is where NMES can help. 2,3

NMES (Neuro Muscular Electrical Stimulation) uses electrical pulses to produce muscle contractions, mirroring the impulse sent from the brain. NMES can be used as a standalone treatment, but is most effective when used in combination with voluntary exercise such as proprioceptive or functional rehabilitation.

By safely controlling the contractions, the muscles can be made to exert themselves much more than the patient would be capable of voluntarily, and without placing additional stress on joints. Additionally, NMES can help the patient to recruit the deep lumbar stabilizers.3,4 This allows patients to effectively and safely strengthen their trunk muscles during exercise, thereby helping to address the causes of low back pain.2,3

However, if symptoms remain, functional rehabilitation for low back pain can still be carried out by combining NMES and TENS in a single treatment. One device with this function is Chattanooga’s Intelect Mobile 2.

Intelect Mobile 2 – the next generation in electrotherapy

Intelect Mobile 2 is an innovative device designed to provide clinicians with everything they need for effective electrotherapy treatment, and comes in three different configurations, STIM, ULTRASOUND, and COMBO.

All three options include an intuitive touchscreen user interface, a library of suggested protocols, and Bluetooth connectivity for easy software updates. And as the name suggests, the device is truly mobile, enabling it to be easily carried or mounted on a wheeled cart.

Intelect Mobile 2 STIM and COMBO provide 2-channel electrotherapy with over 20 different waveforms, offering therapists multiple treatment options. For instance, when treating a patient with low back pain, Channel 1 can be used to deliver TENS treatment for pain relief, while Channel 2 provides muscle stimulation to support functional rehabilitation exercises. Or therapeutic ultrasound can be used as an adjunct pain-relieving modality. 5

Altogether, Intelect Mobile 2 is an excellent option for therapists interested in using electrostimulation for treating not only low back pain, but also a range of other neuromuscular conditions.
