Two of the most common therapies that are recommended for injuries and discomfort are ice and heat. Both ice and heat can be beneficial after an injury. Ice is typically used to reduce swelling, pain and inflammation, while heat is used to increase blood flow, to relax muscle spasms, and promote healing. The type of injury and the stage of healing will determine which is more appropriate. Ice is recommended immediately after an injury and during the acute inflammatory phase. Ice is also helpful in rehab when increasing activity after an injury. In this situation it helps to prevent a flare up. Heat is best reserved for use after the inflammatory stage has passed.
When you apply ice to an injury, it causes the blood vessels in the area to constrict, which decreases blood flow and inflammation. This can help reduce the pain from the swelling. The cold temperature also numbs the nerve endings in the area, which can provide additional pain relief. It’s important to note that in most cases, ice should not be applied directly to the skin, as it can cause frostbite. Instead, it should be wrapped in a towel or cloth before being applied to the injury. Ice massage is done directly on skin, to a small area of inflammation, but should only be done by your physical therapist or physical therapy assistant.
It is generally recommended to use ice immediately after an injury, and to continue using it for the first week. This is considered the acute phase of injury, during which inflammation and swelling are at their highest. Applying ice during this period can help reduce inflammation, and pain. Ice can help speed up the healing process.
Heat therapy can be beneficial for chronic arthritic pain or muscle soreness. When heat is applied to an injury, it causes the blood vessels in the area to dilate, which increases blood flow and oxygen to the affected area. This can help reduce muscle stiffness and soreness, and can also help to relax the muscle. Additionally, heat can warm up the tissue in preparation to stretch and increase the flexibility of the tendons, ligaments and muscles.
There are different types of heat therapy, such as dry heat and moist heat. Dry heat is typically provided by a heating pad, while moist heat is provided by a damp towel or a hot water bottle wrapped in a damp cloth. Moist heat is considered more effective than dry heat as it can penetrate deeper into the tissue.
It’s important to note that heat should not be used immediately after an injury, as it can increase inflammation. Heat should be used only after the acute inflammatory phase of injury has passed. Depending on the injury, the acute inflammatory phase can last a few days to over a week.
When using ice therapy for an injury, it’s important to first consult with a healthcare professional or physical therapist to ensure that ice is appropriate for your specific injury.
Here are some general guidelines for using ice therapy after an injury:
- Apply ice to the affected area as soon as possible after the injury, ideally within the first 48-72 hours.
- Wrap ice in a towel or cloth before applying it to the injury, to avoid frostbite.
- Apply ice for 15 to 20 minutes at a time, and take breaks in between to avoid frostbite. Make sure the skin returns to its normal temperature before reapplying.
- Repeat the process of applying ice for several cycles throughout the day, as needed.
- Be mindful of any numbness or tingling that may occur during application, and remove the ice if you experience any discomfort.
- Use ice after exercises to keep inflammation away as you recover.
- Avoid using ice therapy if you have poor circulation or any other condition that affects your sensitivity to cold.
- Cease use of ice if it causes any discomfort or if your symptoms worsen.
Here are some general guidelines for using heat therapy after an injury:
- Wait until the acute phase of the injury has passed and inflammation has subsided.
- Always use a heat source that can be regulated to avoid overheating the area. A heating pad or a hot water bottle wrapped in a towel are common heat sources.
- Gradually increase the temperature of the heat source to avoid burns or scalds. Start with a low temperature and work your way up.
- Apply heat to the affected area for 15 to 20 minutes at a time, and take breaks in between to avoid overheating the area.
- Always use a barrier between your skin and the heat source to prevent burns.
- Use heat therapy before exercise or physical activity, as it can help increase blood flow and flexibility to the affected area.
- Avoid using heat therapy if you have poor circulation, diabetes, or any other condition that affects your sensitivity to heat.
Alternating between ice and heat therapy (referred to as contrast therapy) can be an effective way to manage pain and inflammation associated with an injury. The idea behind contrast therapy is that the cold from the ice constricts the blood vessels, which reduces inflammation, while the heat dilates the blood vessels, which increases blood flow and oxygen to the affected area.
GameReady is a brand of cryotherapy equipment that is commonly used in the medical and rehabilitation field to provide ice therapy. It is a portable machine that uses compression and cold therapy to help reduce inflammation, swelling, and pain associated with injuries. The device circulates chilled water through a wrap that is placed around the affected area, providing a consistent and controlled cooling to the area.
GameReady is an effective way to provide ice therapy as it delivers consistent and controlled cooling, which can help reduce inflammation and swelling more effectively than traditional ice packs. Additionally, the compression feature of the device can help to reduce pain and muscle spasms, and results in a quicker recovery.
However, it’s important to note that GameReady is a medical device and should only be used under the supervision of a healthcare professional. It’s also important to note that the specific treatment protocols will vary depending on the injury and individual, so it’s best to consult with a healthcare professional.
