Cold Therapy Systems - most frequently asked questions by our customers:  


Feel free to skip this section and jump ahead to our review of cold therapy system options if you already understand the benefits of cold therapy and how it works. 

What is cold therapy?

Cold therapy, also known as cryotherapy, is a therapeutic technique that involves applying a cold temperature to an injured or painful area of the body in order to reduce inflammation, pain, and swelling. This can be done using ice packs, cold compresses, or specialized cold therapy devices. Cold therapy works by constricting blood vessels in the affected area, which reduces blood flow and inflammation, and can help to reduce pain.

It is commonly used post-surgically to reduce pain and swelling, and to speed up the healing process. It is often prescribed by healthcare providers as a safe and effective way to manage pain without the use of opioids or other pain medications. After surgery, cold therapy may be applied using cold therapy machines that deliver a consistent and controlled cooling effect to the affected area. These devices are filled with ice / chilled water, and can be wrapped around the surgical site to provide targeted pain relief. Cold therapy can be particularly beneficial after orthopedic surgeries such as joint replacements, where swelling and inflammation can be a major concern.

Cold therapy can also be used to treat acute injuries such as sprains, strains, and bruises, as well as chronic conditions such as arthritis and tendonitis. Cold therapy is generally considered safe and effective, but it should be used with caution in people with certain medical conditions, such as Raynaud's disease or circulation problems.

Overall, cold therapy is a non-invasive and drug-free way to manage pain and inflammation after surgery, and can help to improve recovery time and overall outcomes. However, it is important to follow the advice of your healthcare provider when using cold therapy post-surgery, as it may not be appropriate for all patients or all types of procedures.

What are the benefits of cold therapy?

Cold therapy machines are most commonly used post-injury and post-surgically where long duration swelling is presentApplying cold/ice to a joint can reduce pain by decreasing the fluid that pools in the joint. Fluid accumulates in the surrounding tissues when there is an increase of blood flow in an area of the body (which occurs when you bump into something or have surgery). This excess pooling of fluid is known as edema (swelling), which increases pressure and pain in the joint. Restricting the amount of blood flow (through blood vessel constriction) can assist with reducing this swelling. Note, your body naturally has the ability to increase or decrease blood flow through the blood vessels, which is typically done to regulate body temperature. For example, in the cold your blood vessels will constrict to maintain better core temperature, whereas in the heat your vessels will dilate to let off excess heat. The constricting of the blood vessels can be encouraged with the application of cold (ice pack, or cold therapy device) to decrease the flow of blood to an injury site. By applying ice right after a surgery, you can reduce the amount of blood pooling at the injury site, by constricting the blood vessels, to reduce the amount of long-term swelling.

Why use a cold therapy device over an ice pack?

Cold therapy devices have many benefits over using basic ice packs. Cold therapy machines provide a continuous, and even distribution of cold on the affected area. Ice packs can only maintain adequate cold temperatures for a very short amount of time as your body temperature warms the ice pack quickly (increasing the temperature of the ice pack and making the cooling impact much less effective). By creating cold therapy more consistently (with a continuous exchange of cool water into the cold therapy pad), cold therapy machines can apply constant cold therapy to the impacted areas much longer. Cold therapy devices also have large, insulated water/ice containers that send very cold water to the cooling pad for many hours (some devices can operate up to six hours or more before you need to replace the water/ice in the reservoir) and this eliminates the need for frequent trips to the freezer to change out ice packs. Cold therapy systems also have pads that are specifically designed and tested for cold therapy. Pads are ergonomically designed for certain body parts (Knee, Hip, Shoulder, Foot, Ankle, etc.) so the surface area of the pad is applying cold therapy to the exact area where it is needed (and avoiding areas where it is not needed). These specific pad shapes for each body part also make them much more comfortable. The pads have strapping to keep the pad secure and in place. Pads are also designed to keep the injury site clean and dry. Ice packs can create condensation (water) as they warm quickly, and this can get surgical sites wet. Cold therapy pads do not have this problem. All of these benefits will assist in accelerating your recovery to get you back to doing the activities you enjoy. 

How do cold therapy devices work?

There are two primary types of cold therapy systems. The main differences are how the devices get the cool water from the cooler to (and from the pad), devices are either non-motorized (gravity fed) or motorized, and they have one or two hoses that connect the cooler to a cold therapy pad, that you place on the affected body part.

Water + Ice

All cold therapy devices include a resevoir (cooler) that you fill with ice and water (There is an indicator line on the inside of the cooler to show you the correct water/ice ratio to make sure you achieve the correct cold water temperature). Pro tip, freeze water bottles and use those as a substitution for ice cubes.

Gravity Fed

Non-motorized devices use gravity (you lift and lower the cooler to fill the pad). For example, the Aircast Cryo/Cuff devices require you to lift and lower the cooler for circulation as it is gravity operated. This device only has one hose going from the cooler to the pad so the water is either flowing from the cooler to the pad, or the pad to the cooler, with no ability for a constant circulation.

Motorized

Motorized devices automatically provide constant recirculation of cold water between the cooler and the pad. These devices use two hoses; where one hose is sending water to the pad, and one is returning water to the unit. Within this motorized category there are two ways the motor is set up to circulate water. The first, which the DonJoy IceMan series of devices use is called a dual pump recirculation. These devices combine some of the return water that was just in the pad (which has been warmed up slightly from your body heat) with the cold water that was sitting the cooler for a more comfortable constant cold. This prevents freezing inlet temperatures in the pad. The other circulation option, offered by the Breg (Wave, Cube, Kodiak, Glacier, VPulse) and Ossur Cold Rush devices, take water straight from the cold cooler and circulate that throughout the pad. The Ossur device has an adjustable flow dial to adjust temperature, and the Polar Care Wave have two flow rate settings for flow.

What are the benefits of compression?

The final difference in devices is compression. Some devices such as the Breg VPulse, and Breg Wave, inflate the pad (with air pressure) to apply medical grade compression to a wound or injury site. The compression is applied intermittently (on/off) in time cycles.

Applying intermittent compression to the wound site can be an added benefit to accelerate your recovery depending on your condition (check with your doctor first). By using compression on the wound (or injury) site, you are pushing fluid away from the joint to allow for a reduction in swelling. This can be used in addition to cold therapy to increase circulation in the joint by further reducing the pooling at the joint. The Breg VPulse and Breg Wave devices offer cold therapy pads that include medical grade compression. 

Compression is also helpful if you are having a bilateral hip or knee operation (or other procedure where you may be less likely to get up and move around post-operatively) and therefore at higher risk of developing a blood clot, called DVT (Deep Vein Thrombosis). The Breg VPulse has an add-on feature for DVT Prevention using compression Calf Pads. These pads operate on a one-minute cycle where for thirty seconds one pad will provide compression to the left calf muscle, followed by thirty seconds of compression to the right calf muscle. This is to encourage blood flow of the lower limbs after surgery. It is always best to follow the exercise advice of a physiotherapist to promote continuous blood flow in the limbs after surgery. The DVT compression calf pads may be an additional option for you to increase circulation. Please note, it is up to your physician to determine based off your medical history if compression is appropriate for you as individuals with a history of blood clots should not use compression. 

What is the difference between a universal pad and a body part specific pad?

A universal pad is a generic shape that can be used in multiple locations and in various orientations. Body part specific pads are designed with that body part in mind for best coverage and ease of application. Check out all of our cold therapy pads here.

Can I use two pads at once?

Yes! Some units have the capability of connecting two pads at once. A purchase of a Dual Pad Y Connector would be required in order for two pads to be used simultaneously together. All Breg, Ossur, and DonJoy IceMan devices have this capability. The only units that will not allow for dual pad connection are the Aircast Cryo/Cuff devices.

What is an insulation barrier?

All devices, except the Polar Care Wave and VPulse, require an insulation barrier to be placed between the pad and your skin to avoid the possibility of freezing of the skin. The Breg devices have an optional peel and stick sterile paper barrier for use with the Polar Care Cube, Kodiak, Glacier devices. You can use a thicker or thinner insulation barrier (ex: hand towel, shirt, pants) to adjust how much cold is applied to the joint. You can find the barriers here in our cold therapy accessories

Can I use cold therapy while I'm sleeping?

Health professionals advise against you using these products while sleeping as we want to ensure you check on the surgical or injury site frequently to make sure you are taking the necessary breaks from icing so you do not freeze the skin. 

What are the most important factors to consider when I am selecting a cold therapy system?

  1. Motorized or Non-motorized? Do you want the system to automatically circulate the cool water for you or are you OK to raise and lower the ice/water container every 20-30 minutes (with a gravity system to allow the cool water to flow in/out of the pad). Motorized units deliver more consistent cold therapy pad temperatures and are more convenient. Gravity fed units are more cost effective and can still deliver efficient cold therapy.
  2. Do you require medical compression in addition to cold therapy? Compression is a nice addition to cold therapy that can aid in healing, but it is not always needed or recommended. Make sure you consult with your doctor to see if compression would be beneficial for you.
  3. Does it fit within your budget? Cold therapy system prices range from under $200 (for the gravity fed versions) and up to $600+ for the systems with compression. If you think you will only use cold therapy for a single surgery maybe going with the less expensive option is the better choice (or perhaps you want to simply rent). However, if you want to have a device that might be used for multiple surgeries or ongoing for injury and pain relief, perhaps a higher priced unit (with more features) is a better investment. A quick note about cold therapy rentals: in our experience if you think you will need cold therapy beyond one month (which is very possible in most cases) then purchasing is usually the better option from a cost and value point of view.
