Red Light Therapy for Sprained Ankle - Benefits and Usage

Introduction: Red Light Therapy for Sprained Ankle

A sprained ankle is a common type of injury that results in pain, swelling, and limited mobility. The pain may be caused by abnormal stress on the ligaments of the ankle. The condition must be treated; otherwise, you will be unable to walk, run, or lift heavy objects. Most people like to heal sooner without experiencing the side effects caused by drugs or waiting for an extended time. Science has introduced red light therapy, which may heal and reduce the effects of a sprain. You can learn about the incredible benefits of red light therapy for a sprained ankle, how it works, and how it facilitates recovery.

Understanding a Sprained Ankle: Causes and Symptoms

A sprained ankle is caused when your ankle rolls, twists, or turns uncomfortably. Doing so stretches or even tears the ligaments in the ankle. Ligaments are what join two bones together and enable your joints to move freely. When the ligaments are stretched or torn, it becomes painful, swelling occurs, and it becomes challenging to move the ankle.

Symptoms of a sprained ankle usually include pain, particularly when you put weight on the injured foot. You may also experience tenderness when you place your hand over the affected area, accompanied by swelling, bruising, decreased range of motion, and a popping noise or sensation on the day the injury occurred. This type of injury is often very common among sports activities, such as running or walking on uneven ground. The primary factors that lead to a sprained ankle are a sudden rolling in or out of the ankle or a clumsy landing after taking a jump.

Traditional Treatments for Sprained Ankles: Limitations and Challenges

A sprained ankle is a common injury, and individuals often attempt regular treatments to alleviate their discomfort. One of the therapies for this is the RICE method: Rest, Ice, Compression, and Elevation. Individuals utilize these techniques and notice a decrease in swelling and pain because resting allows the ligaments time to heal, and ice reduces swelling and numbs the pain. Compression with an elastic bandage helps control swelling, and elevating the ankle above the heart level helps decrease blood flow to the area, which also reduces swelling. However, while RICE is great for relieving symptoms of a sprained ankle, it will not help with repairing damage to the ligaments. Additionally, the patient would have to restrict their activities for weeks or months, which can be problematic for individuals who lead active lifestyles.  However, drugs such as painkillers or anti-inflammatory medication are usually employed to alleviate pain.  Although such drugs can help reduce pain, they can also cause other medical problems, such as addiction to the painkillers or gastrointestinal problems. A sprained ankle can also be treated through body therapy, but the outcome requires patience, effort, and determination.

How Red Light Therapy Helps Heal a Sprained Ankle

The Science Behind Red Light Therapy for Injury Recovery

Red light therapy utilizes specific wavelengths of red and near-infrared light as a non-invasive, drug-free treatment.  These wavelengths induce biological responses that accelerate healing by penetrating the skin.  Red light therapy makes the ligaments in injured ankles stronger by stimulating the mitochondria in the cells of the ligaments.  It is the mitochondria that generate the energy molecule ATP. This energy enables a range of cellular activities, including metabolism, mitosis, and the conversion of essential ions.  Since the cells of the ligaments have more energy, they rapidly divide, thus accelerating the healing process.

Red light therapy also increases blood flow to the damaged region, providing cells with a better supply of oxygen-rich blood. Blood delivers oxygen and nutrients to the injured area, enabling cells to generate more energy and heal more quickly. Red light therapy also helps minimize inflammation and pain associated with ligament tears. Red light therapy alleviates pain by stimulating the release of endorphins, natural painkillers, and reducing inflammation by inhibiting the synthesis of pro-inflammatory cytokines. Red light therapy also induces collagen synthesis, a major structural protein in ligaments. Thus, red light therapy alleviates pain and swelling in a sprained ankle and successfully treats the injured ligaments.

Does Red Light Therapy Work for Sprained Ankles? Research Insights

Red light therapy is gaining popularity due to its outstanding advantages in the recovery of various injuries, such as sprained ankles. While research on the application of red light therapy, particularly for sprained ankles, is in its early stages, the initial studies and research have presented encouraging and optimistic results. Several studies have demonstrated that red light therapy can aid in the recovery of injured and ruptured ligaments and tendons. Furthermore, these studies indicate that red light therapy can substantially minimize pain and inflammation caused by such injuries.

Clinical Studies Supporting Red Light Therapy for Ankle Injuries

Study 1: Effectiveness of Red Light Therapy (λ627 ± 10 nm) in Treating Acute Ankle Sprains

Objective

The purpose of this study was to test the efficacy of light-emitting diodes (LED) at a wavelength of λ627 ± 10 nm and an energy density of 10 J/cm² in treating acute grade II ankle sprain. The procedure was performed in 40 individuals, who were divided into two groups: the first group received LED therapy, and the second group received a placebo (LED off). All the participants underwent the PRICE (protection, rest, ice, compression, and elevation) protocol for treatment.

Results

The group given LED treatment claimed significantly less pain than the placebo group, as measured by two pain scales: the visual analogue scale (VAS) and McGill Pain Questionnaire. To be precise, the LED group reported a 55.73% decrease in pain on the VAS and an 83.33% decrease on the McGill scale, while the placebo group reported decreases of 85.79% and 52.52%, respectively. In addition, the LED group showed a greater reduction in swelling (oedema) on the 3rd and 6th days following treatment, with a statistically significant difference compared to the placebo group (p < 0.0001).

Conclusion

The research indicated that LED treatment, utilizing a specific dose and wavelength of λ627 ± 10 nm, is effective for pain relief and reduction of swelling during the initial phase of ankle sprains. It is a favorable alternative or supportive treatment for curing acute injuries such as sprained ankles.

Study 2: Effectiveness of 830 nm Near-Infrared LED Therapy for Treating Sports Injuries in Athletes

Objective

The current study aimed to evaluate the efficacy of a hands-free near-infrared (IR) light-emitting diode (LED) therapy device (Omnilux Rehabilitation System) in the management of various sports injuries. The device emitted light with a wavelength of 830 nm and an energy density of 180 mW/cm². The goal was to determine whether this system could provide speedy and efficient healing for athletes, enabling them to return to training and competition rapidly, thereby minimizing the need for therapist-intensive treatment.

Results

Twenty-eight patients with complaints of joint pain, tendinopathies, muscle pain, and back pain were treated. Among these, 17 patients responded excellently. Both acute and chronic types of pain responded effectively to IR LED treatment, with no side effects reported in any of the cases. Subjects were comfortable with the procedure, and professionals found the system to be simple to apply and safe. Dosages for treatments were applied at 54 and 108 J/cm² (using exposure durations of 5 and 10 min), but recommendations were made to utilize higher doses to achieve better effects.

Conclusion

The study indicated that 830 nm IR LED therapy was an encouraging and effective treatment for addressing various types of sports injuries. It represents a convenient, non-invasive, and safe alternative to normal methods of treatment. Large controlled trials will, however, need to be undertaken to confirm these results fully and provide greater statistical evidence.

Choosing the Right Red Light Therapy Device for a Sprained Ankle

Key Features to Look for in a Quality Device

It is essential to purchase the appropriate red light therapy equipment when planning to perform red light therapy at home. An accurate red light therapy equipment should be able to emit therapeutic wavelengths of red and near-infrared light. When purchasing a red light therapy machine, it is essential to look for these characteristics, as numerous units on the market claim to provide efficient red and near-infrared light but are merely light sources. Conversely, a good red light therapy gadget can produce red light in the range of approximately 610–660 nm as well as infrared light in the range of about 830–1064 nm, since these are therapeutically proven wavelengths of red and near-infrared radiation. 

A low-cost device features both incandescent bulbs and fluorescent bulbs, neither of which is capable of providing focused light. On the contrary, the proper red light therapy equipment utilizes LEDs as the light source, and LEDs alone are capable of emitting concentrated red and near-infrared light. Proper red light equipment should have the correct power output or irradiance. A robust yet non-hazardous light output of 30–100 mW/cm² ensures that sufficient energy is delivered to the damaged tissues without overheating the skin.

Treatment area size is also essential—larger panels cover more area at once, which is helpful if you need to treat a larger area in one go and save time. A good red light therapy unit should also have variable settings for session duration and power, allowing for greater control depending on your comfort level and the severity of your injury. Portability and convenience also matter, particularly if you will be using the device often at home. Finally, always select a device that is FDA-cleared or supported by clinical testing. This ensures that the product is safe and effective for therapeutic use.

Best Practices for Using Red Light Therapy on a Sprained Ankle

Finding the Right Dosage: Frequency, Session Length, and Distance

When you begin using red light therapy, it is crucial to determine the correct dose to achieve safe and effective outcomes. The three most important factors to consider are the frequency of application, the duration of application, and the proximity of the device to your skin.

Now, let's discuss frequency. The number of times you operate the device during a week depends on the severity of your injury and the device you have. Generally, patients are recommended to begin with perhaps 3 or 5 sessions per week. As your body begins to heal, you may either maintain the same routine or adjust it according to how you feel and the progress you observe.

Session duration comes next. The duration of each session of red light therapy is also crucial. Sessions typically take anywhere from 5 to 20 minutes. Begin with approximately 10 minutes initially. If your body doesn't complain and you're getting good results, you can gradually lengthen the sessions. Spending too much time under the light can sometimes be uncomfortable, so it's better to go slowly.

Lastly, distance is also a significant factor. The distance between the device and your skin generally has to be between 4 and 12 inches. If you hold the device too close, your skin can become too hot or inflamed. If it is too far away, you would not receive adequate light for healing. Following the manufacturer's guidance and adjusting slightly based on your comfort level will yield the best results from the therapy.

Conclusion: Why Red Light Therapy is a Smart Choice for Sprained Ankle Healing

Can I Heal My Sprained Ankle with Red Light Therapy? 

Yes, you can heal your sprained ankle with red light therapy. Red light therapy utilizes specific wavelengths of red and near-infrared light that penetrate deeply into your skin and tissues. When these lights hit the damaged area, they increase the energy production within your cells, which allows them to heal faster. Red light therapy also enhances blood flow, delivering more oxygen and nutrients to your sprained ankle, thereby accelerating the healing process. It also reduces swelling, relieves pain, and decreases inflammation—all of which are typical with a sprain.

What is Ultrasound Therapy for Sprained Ankle?

Ultrasound therapy for a sprained ankle is a form of therapy that treats the area with sound waves, allowing the injured area to heal more quickly. During this therapy, a small device known as a transducer is gently rolled over your sprained ankle. It delivers high-frequency sound waves deep within the tissues. The sound waves produce small vibrations that cause the tissues inside to warm up. This heat aids in the acceleration of blood flow, loosening tight muscles, reducing swelling, and promoting the repair of torn ligaments. Ultrasound may also help in the breakdown of scar tissue and improve flexibility during recovery.

FAQS: Addressing Common Questions

Can red light therapy heal torn ligaments?

Yes, red light therapy can aid in the healing of torn ligaments, but it does not instantly repair them. Red light therapy stimulates the recovery of torn ligaments by enhancing natural healing mechanisms, including the activation of mitochondria and the reduction of pain and inflammation.

What is the best therapy for a sprained ankle?

The optimum treatment for a sprained ankle commonly begins with R.I.C.E. (Rest, Ice, Compression, Elevation) to manage swelling and pain. Physical therapy is helpful in the rehabilitation of strength and flexibility. Red light therapy and ultrasound therapy can further accelerate healing for improved recovery.

Is light exercise good for a sprained ankle?

Yes, light exercise may be beneficial to a sprained ankle after the initial swelling and pain have diminished. Gentle movements restore flexibility, circulation, and keep the joint from stiffening. Always begin slowly and follow the recommendations of a doctor or therapist to avoid re-injury.
