How To Rehab Calf Strains

Tweak your calf after some physical activity? Maybe you have pain behind your knee or right in the muscle belly of your calf. No worries, we’re here to help get you back on track teaching you how to rehab calf strains! Our calf musculature which is situated on the back of our lower legs consists of three muscles, and can often be subject to injury if they are under too much load and/or not appropriately strengthened! Various calf strains are often seen in runners, tennis players, other athletic populations, and even weekend warriors. Follow along in this article as we break down exactly what this injury is, as well as how to rehab calf strains appropriately!

 

Understanding The Calf Muscle Complex

The ‘calf muscle’ is actually a complex of 3 muscles, which includes the gastrocnemius, soleus, and plantaris. These muscles each travel down the back of the lower leg and join the Achilles tendon, which then inserts onto our calcaneus (heel bone). The gastrocnemius muscle has two heads: a medial head and lateral head, which is situated superficial to the deeper soleus muscle. What is unique about the gastrocnemius in contrast to the soleus is that it is a 2-joint muscle, as it crosses both the knee joint as well as the ankle joint. This is similar to the rectus femoris at our hip, which acts as a hip flexor and knee extender.

What is A Calf Strain

How to rehab calf strains you ask? First, you must understand what the injury is! A strain is an injury to either a muscle and/or tendon, resulting in partial or complete tearing. This is different than a sprain, which is partial or full tearing secondary to injury of a ligament, such as the anterior cruciate ligament (ACL) for example. Calf strains can occur in one of the three muscles that make up the calf complex that was explained above. Let’s break down each of these strains in more detail. For the scope of this article, we will cover gastrocnemius and soleus strains, as plantaris strains are quite rare.

Gastrocnemius Strains – The Power Generating Muscle

In the text titled Sports Injuries by Dreddie and David, the authors described that the calf injury was first described in the year 1883 as it was associated with the sport of tennis, thus receiving the name ‘tennis leg’. This particular injury is in relation to the gastrocnemius muscle, with a common mechanism of injury of knee extension (straight knee position) and ankle dorsiflexion. The gastrocnemius is particularly more susceptible to strains due to it crossing 2 joints. In addition, in contrast to the soleus muscle that is more of an ‘endurance’ muscle, the gastrocnemius has an abundance of type II muscle fibers (fast-twitch), which are utilized specifically for speed and power-based activity. Muscle strains are more likely to occur in these types of muscles that are fast-twitch and cross multiple joints.

Common signs and symptoms of a gastrocnemius strain include: 

  • Feeling something has ‘hit’ the calf

 

  • Potential audible ‘pop’ sensation

 

  • May not have immediate pain, but as you begin to take steps, the pain will appear and be significant

 

  • Difficulty rising up on toes after injury

 

  • Potential swelling in the calf muscle region

 

Soleus Strains – The Endurance Muscle

Soleus strains are a bit more difficult to differentiate due to their ‘non-specific’ symptoms and gradual onset. This muscle is also more intimately associated with the Achilles tendon, and sometimes the clinical presentation of these two anatomical regions can closely mimic one another. These musculotendinous injuries are more commonly seen in distance runners. In fact, when we run, our soleus is loaded with 6-8 times our body weight! While the gastrocnemius is more commonly injured with the knee in an extended position, the soleus is more likely to be strained with the knee in a flexed position.

Research by Balius and Capdevilla discusses that the soleus muscle is made up of 96% type I muscle fibers, which are utilized specifically for endurance-based activity. This is why the soleus is more susceptible to injury with activities like distance running. It can also present itself in the elderly and middle-aged population, especially if poorly conditioned.

Common signs and symptoms of a soleus strain include: 

  • Non-specific, gradual onset of a ‘dull ache’ sensation behind the lower leg closer to the Achilles tendon

 

  • Pain with resisted plantarflexion (pushing down with foot) while the knee is bent

 

  • Pain that becomes worse with activity and subsides with rest

 

  • May start as tightness and discomfort and become more aggressive with prolonged activity

 

How to Rehab Calf Strains: Major Differences Between Gastrocnemius Versus Soleus Strains

What Do I Do If I Injured My Calf?

The most important first step in rehabbing calf strains is to differentiate which muscle is injured, as management will be slightly different. Once that is established, it is also beneficial to ascertain the severity of the injury. Most calf strains are graded level I through III, with I being a mild strain and level III being complete tearing of the muscle. Most calf strains can be treated conservatively, but with some grade III injuries, these may need to be managed surgically. A physical therapist can initially evaluate you to decipher if you need further consultation after a calf strain. If a complete tear is suspected, a sports medicine physician or orthopedic surgeon may utilize either guided ultrasound or an MRI to assist in a proper diagnosis.

How Is This Different Than an Achilles Injury?

Sometimes, an Achilles tendon injury can be confused for calf strains, and vice versa, due to their intimate association with one another. Achilles tendinopathy starts similar to a soleus strain, with more of a chronic, overuse type of injury. The pain will be lower than the location of the soleus muscle at the Achilles tendon and can either be mid-substance (in the middle of the tendon) or at the location of the insertion point at the heel (calcaneus). An Achilles tendon tear is more similar to a gastrocnemius muscle strain, as this occurs acutely with a specific activity, often in jumping-related sports. A common subjective report of someone feeling they have gotten kicked in the back of their leg is similarly reported with an Achilles tendon tear as well.

How To Rehab Calf Strains: Understanding Progressions

The general principles of treating calf strains are similar to other soft tissue injuries, which includes: 

  • The initial period of relative rest following the POLICE principle
    • The POLICE principle follows the simple principles of not only early protection of the injured site but also early loading to facilitate tissue healing

 

  • Early loading of the muscle(s) involved with progressions from
    • Isometrics (static contractions),
    • To isotonics (full motions),
    • And an emphasis on eccentric training (muscle lengthening against gravity) as well as other heavy, slow loading techniques in the later phases

 

  • Return to activity with graded exposure specific to individual demands during the final phase

 

Other aspects of care that may assist in modulating symptoms include dry needling, foam rolling, instrument-assisted soft tissue massage (IASTM), and other manual therapy techniques by a physical therapist or another healthcare provider. Although these aforementioned interventions are not supported by high-quality evidence, they still may provide some benefit in case-specific situations. To see an example of another common soft tissue injury and how it is managed, read below on how to manage a hip flexor strain!

Early Phase Exercises For Calf Strains

Next, we will dive into an example of progressive exercises after a calf strain! Here, we start with the basics of isometrics and isotonics.

Ankle Plantarflexion Isometrics – In Neutral

Sample Achilles [P]Rehab Program Exercise Video

Isometrics are a great place to start after soft tissue injuries. Isometrics are static contractions of a muscle, that will promote early facilitation, blood flow, and an analgesic effect to modulate some pain an individual may be experiencing. 

  • HOW: In a comfortable sitting position with your feet out in front of you, place a resistance band around the balls of your foot.  Keep your foot in a neutral position, with the toes pointed straight up and your ankle at a 90 deg right angle. This is your starting position. Slowly pull on the resistance band to increase the resistance but do not let your ankle move. The more you pull on the band, the harder it will be to maintain your ankle position.

 

  • FEEL: You should feel the muscles in your calf behind your lower leg working.

 

  • COMPENSATION: Do not let the ankle move!

Calf Foam Rolling

Foam rolling of the calf complex can be beneficial in the early phase to enhance blood flow and start to mobilize the tissue that is irritated from the injury. Be sure to listen to your body and not push into significant symptoms of pain; however, some mild discomfort that is tolerable can be expected in the early phase with this technique.

 

Improve Ankle Dorsiflexion Mobility

You don’t necessarily want to aggressively stretch a calf strain in the acute phase, however, it is imperative you regain ankle dorsiflexion range of motion when the timing is right as limited ankle dorsiflexion is a modifiable risk factor for other injuries like an ankle sprain or Achilles tendinopathy. As your body is willing to allow it, begin working into this range of motion, and week by week you’ll see progress! Here is a great video that breaks down various exercises you can try!

 

Heel Raise Isometrics

Closing Thoughts

Calf strains have a good prognosis and people often make a full recovery! Generally speaking, strains can vary in recovery times from a couple of weeks up to several months if there is a more significant injury. The first step after this injury is to ensure you receive a proper diagnosis, as the calf muscle is actually ‘3 muscles in one’, and therefore, you must establish which one of these muscles has been insulted. From there, a physical therapist can help you optimize your recovery with appropriate exercise and activity modification.
