How Cold Compression Therapy Works

Pain and swelling of a torn, sprained or pulled muscle is associated with inflammation in the injured soft tissues. The sooner swelling and inflammation is controlled following an injury, the quicker the injury will heal and the sooner you can return to participation.

The universal medical procedure for sprains, strains, pulled muscles and injured soft tissues is Ice and Compression to control swelling, inflammation, and pain.

Injuries to the shoulder, back, calf, hamstring, and shin are among the most difficult to treat with ice. The use of a medical quality Ice Compression Wrap is ideal for these difficult areas.

Cold compression therapy constricts the blood vessels and slows down the metabolism of the cells. The reduced metabolism lowers the need for the oxygen and nutrients and slows the rate of cell death and the resulting excess build up of blood and fluid. This excess build up is the inflammation.

Until you stop the inflammation, your injury will not heal.

Cold compression therapy also has a numbing effect on the nerve endings decreasing the impulses to the brain perceived as pain.

Place a Cold One® wrap in your home freezer for 2 or more hours and then apply to your injured area. The wrap is fully adjustable for compression to stop swelling and the icing factor will last about 15 to 20 minutes to stop pain. The wrap can be worn longer as the compression is beneficial, but due to the design, the gels give up the frozen state when icing is complete so there is no danger of over icing. The rubberized linen liner protects your skin from cyroburn and use of the wrap is completely safe!

MDs and Sports Injury professionals advise R.I.C.E.

REST Rest and elimination of activity which aggravates the injury.

ICE Apply Cold to stop pain and restrict excess Fluid to the injury.

COMPRESSION To further inhibit swelling caused by excess Fluid to the injury.

ELEVATION To further inhibit swelling caused by excess Fluid to the injury.

Cold One® wraps deliver both cold therapy and compression therapy at the same time. The combination drives the cold deeper into the injured tissue than ice packs, "frozen peas", or frozen chemical gel bags.

Cold One®’s neoprene outer layer provides added insulation and prevents sweating on the outside while our specifically milled inner liner (stretchable, very tough) prevents sweating on the inside and protects skin from cryoburn. The Cold One® wraps are not only effective, but comfortable when worn against the skin or over clothing.

The gel capsules are strategically sewn in place for each wrap to effectively provide cold coverage where it is needed. The individual gel capsules conform to the body curvature for a close comfortable fit. Other wrap manufacturers save money by using nylon, which can fatigue after repeated freezing, instead of neoprene and using inserts which are hard to place and unreliable and uncomfortable. They may provide cold, but not compression, don’t have durability and don’t come close to driving cold as deep as Cold One® wraps.

Cold One® offers a wide variety of products for specific injury areas. Each product utilizes the combination of cold therapy and compression therapy. The cold factor lasts about 20 minutes as recommended by medical professionals and trainers, and the compression therapy continues as long as the wrap is worn. Re-freeze and reuse.

Cold One® wraps should be used several times a day and everyday until you have recovered your range of motion without pain. The most effective use of a cold compression wrap is when it is worn after repetitive muscle use such as pitching, throwing, swinging, running, twisting, lifting,etc. Any muscle which is sore or swollen after exertion benefits greatly by immediate use of a Cold One® wrap. Make it part of your regular exercise routine.

What is a muscle Strain?

A muscle strain is a stretch or tear of muscle fibers. In the legs, arm, shoulder or back, muscle strains happen when a muscle is either stretched beyond its limits or forced into extreme contraction. Because the body has many different muscles, it is vulnerable to several different types of muscle strains. Some of the more common ones are:

Gastrocnemius strain (calf-muscle pull) — Calf muscle strains typically occur when the foot suddenly bends upward, stretching the calf muscle beyond its limits. At the time of injury, you may actually hear or feel a pop inside your calf — the sound of the muscle tearing, or shearing away from the Achilles tendon. Calf muscle strains are common in athletes, especially tennis players and joggers. However, they also can happen during a simple stroll, if your foot flexes upward when you step into a hole in the sidewalk, or if your heel slips off the edge of a curb.

Plantaris strain — The plantaris is a thin muscle that begins at the lower end of the femur (the large bone of the upper leg), stretches across the knee joint and attaches to the back of the heel along with the Achilles tendon. Because the plantaris doesn't contribute much force in bending the knee, a tear in this muscle may not seriously affect your knee function. However, a severe plantaris strain can cause significant pain, usually at the back of your calf rather than near the knee. A plantaris strain can occur alone or accompany a gastrocnemius strain or a tear of the anterior cruciate ligament (a major, stabilizing ligament in the knee).

strain (pulled hamstring) — Hamstrings are long muscles that extend down the back of the thigh. Because hamstrings work to pull back the leg and bend the knee, they can be injured during running, kicking or jumping. As in gastrocnemius strain, you may feel a pop, usually at the back of the thigh, when the muscle tears.

Quadriceps strain — The quadriceps are a large group of muscles in the front of the thigh that straighten out the knee, an opposite action from the hamstrings. Like hamstring strain, quadriceps strain is a common injury in runners. However, it also may occur during a strenuous leg press at the gym. The pain of a quadriceps strain is felt in the front of the thigh, and the strain may be described as a "groin pull" if the tear occurs fairly high in the muscle. To help simplify diagnosis and treatment, doctors often classify muscle strains into three different grades, depending on the severity of muscle fiber damage.

Grade I — Only a few muscle fibers are stretched or torn, so the muscle is mildly tender and painful, but muscle strength is normal.

Grade II — A greater number of muscle fibers are torn, so there is more severe muscle pain and tenderness, together with mild swelling, noticeable loss of strength and sometimes bruising (called ecchymosis).

Grade III — The muscle tears all the way through. Either it rips into two separate pieces, or the fleshy part of the muscle breaks away from the tendon. Grade III muscle strains are serious injuries that cause complete loss of muscle function, as well as considerable pain, swelling, tenderness and discoloration. A Grade III strain also causes a break in the normal outline of the muscle, often producing an obvious "dent" or "gap" under the skin where the ripped pieces of muscle have come apart.

In the United States, leg, ankle, elbow,shoulder (rotator cuff) and back muscle strains account for more than a million office visits to doctors every year. More than half of these injuries happen to active young adults between the ages of 25 and 44. Men are twice as likely to be injured as women. On the job, leg strains, sprains and tears are the second most common type of work-related injury in American adults, with approximately 100,000 cases reported annually to the U.S. Bureau of Labor Statistics. Muscle strains also are common among teenage athletes, especially those who participate in football, soccer or wrestling as well as older or retired athletes who still exercise with prior muscle injuries.


Symptoms of a strained muscle can include:

  • Muscle pain and tenderness, especially after an activity that stretches or violently contracts the muscle.
  • Pain usually increases when you move the muscle, but it is relieved by rest.
  • Local muscle swelling, black and blue discoloration or both.
  • Either a decrease in muscle strength or (in a Grade III strain) a complete loss of muscle function.difficulty moving, lifting, or exercising,
  • A pop in the muscle at the time of injury.
  • A gap, dent or other defect in the normal outline of the muscle (Grade III strain)


Your doctor will want to know what activity triggered your muscle pain and whether there was a pop in the muscle when you injured it. The doctor also will ask about your symptoms, especially any decreased muscle strength or difficulty in normal use of the muscle.

Your doctor may suspect that you have a strained muscle, based on your symptoms and the history of your injury. To confirm a diagnosis, the doctor will perform a physical examination. If the results of your exam point to Grade I or II muscle strain, then usually you will not need any additional testing. However, if the diagnosis is in doubt, X-rays or a magnetic resonance imaging (MRI) scan may be necessary. Also, in calf muscle injuries, Doppler studies may be done to check for a blood clot.

Expected Duration

Most Grade I or Grade II strains begin to feel better within a few days. In most cases, symptoms are either totally gone, or very much improved, within eight to 10 weeks. Symptoms of a Grade III strain may persist until the torn muscle is repaired surgically.


To help prevent muscle strains, you can:

Warm up before you participate in high-risk sports. Follow an exercise program aimed at stretching and strengthening your injured or sore muscles. Increase the intensity of your training program gradually. Never push yourself too hard, too soon.


If you have a Grade I or Grade II strain, your doctor will probably recommend that you follow the RICE rule:

Rest the injured muscle (take a temporary break from sports activities).

Ice the injured area to reduce swelling.

Compress the muscle with an elastic bandage.

Elevate the injured leg.

In addition, you can take a nonsteroidal anti-inflammatory drug (NSAID), such as ibuprofen (Advil, Motrin and other brand names) or aspirin, to ease pain and relieve swelling. As pain gradually subsides, your doctor may recommend a rehabilitation program to restore the normal range of motion in your leg and to gradually strengthen the injured muscle.


For many Grade II strains, evaluation by a specialist, such as an orthopedist, will be appropriate. To allow the injured muscle to heal, you may need to wear a cast for a number of weeks.

If you have a Grade III strain the torn muscle may need to be repaired surgically by an orthopedic specialist. One exception is a Grade III plantaris strain, which usually is treated without surgery.

When To Call A Professional

Call your doctor promptly if:

  • You hear or feel a pop in your muscle at the time of injury.
  • You have severe pain, swelling or discoloration in the injured muscle.
  • Your injured muscle is obviously weak compared to your opposing uninjured muscle.
  • You have muscle pain.
  • You have milder muscle symptoms that do not improve after 48 hours
  • Muscle Injury Prognosis

  • The prognosis depends on the location and severity of the muscle strain. In general, almost all Grade I strains heal within a few weeks, whereas Grade II strains may take two to three months. After surgery to repair a Grade III strain, most patients regain normal leg muscle function after several months of rehabilitation.
