Soleus strain: Cause, Symptoms, Treatment, Exercise -

What is soleus strain?

A soleus muscle strain occurs due to muscle fibers are damaged by the loads placed on them by jerky activity. The soleus muscle is injured while the knee is in flexion. Strains of the proximal medial musculotendinous junction are the most general type of soleus muscle injuries. It crosses only the ankle and is largely a term of type one slow-twitch muscle fibers.

Soleus injuries are relatively common in runners. This type of injury is known as an overuse injury, which is why endurance and long-distance runners are at higher risk. Injuries commonly occur as a result of fatigue or over training. They can also occur when the knee is flexed for a long time while running, such as during uphill running.

Anatomy of Soleus muscle

Soleus muscle is a flat, broad muscle of the calf of the leg lying just beneath the gastrocnemius muscle. It arises from the upper part of the tibia and fibula, the bones of the lower leg, and then attach to the gastrocnemius to attach via the Achilles tendon at the heel.

It is a large muscle located in the posterior leg. The soleus and gastrocnemius, along with the plantaris muscle, belong to the group of superficial posterior compartment calf muscles.

Origin:

Proximal half of back surface of tibia along soleal line.
proximal 1/3 of the posterior fibula.

Insertion:

Posterior heal via a calcaneal tendon.

Nerve supply:

Its supplied by the tibial nerve, L4, L5, S1, and S2. it has no sensory supply to the intramuscular aponeurosis.

Blood supply:

Its supplied by branches of the popliteal artery trunk, the posterior tibial artery, and the peroneal artery.

Antagonists of soleus: Tibialis anterior

What causes of soleus strain?

Soleus muscle strains generally occur when someone suddenly moves or overstretches their soleus after standing more time.Fast pivots, jumps or abrupt stops can cause strains. This injury is mainly common when toes get forced upward (toward body) and ankle pulls soleus muscles down too rapidly.

An acute soleus muscle strain is once muscle tears rapidly and unexpectedly. muscle tears will happen either from injuries or trauma. this will result to:

• Not warming up correctly before physical activity
• deficient flexibility
• deficient conditioning
• Overexertion and fatigue
• calf muscle Weakness

Acute soleus muscle strain:

Slip body, jump, run, throw something, raise something heavy, lift something while clumsy position.

Chronic soleus muscle strain:

Sports like row, tennis, golf, or baseball, poor posture, holding back or neck in an ungainly position for long periods of time, like after work at a desk.

Overuse:

Repeating a similar movement, whether or not at work or during an associate activity like taking part in sports — will cause overuse syndrome.

Don’t stretch or warm up prior to exercise: Stretching prior exercise step by step will increase how much stress you place on muscles.

A lack of flexibility: If you’re not much flexible, your calf muscles (and the fibers in them) are tighter, which build them additional susceptible to strains.

Other risk factors for soleus strain

Age: People over 40 may be more likely to obtain strains during physical activity.

Sex: Men are more likely to get calf muscle injuries.

Lack of conditioning: It’s important to warm up and stretch prior to physical activity and condition
muscles before he start of a sports season.

Muscle quality: individuals with tight or short calf muscles have a more risk of calf strains.

Grades of soleus strain

Grade 1: Grade 1 injury causes minimal muscle damage, although there may be sharp pain at the time of injury. May be able to continue an activity, without pain or with mild discomfort.
Average time to come back to sport:10-12 days
sign-pain on unilateral calf raise.

Grade 2: Grade 2 injuries cause moderate muscle damage, and people with this category of muscle injury may have difficulty walking. They will often experience a sharp pain that worsens when they flex or extend their foot.
Average time to come sport:16-21 damage days
sign-pain with active plantar flexion, pain and weakness with resisted plantar flexion, loss of flexion.

Grade 3: A grade 3 injury is a complete tear of the muscle, and it can cause significant bruising and swelling in the calf.Full recovery can take three to four months and, in some instances, surgery may even be needed.
Average time to come sport: 6 months once surgery
sign-inability to contract calf muscle may have the palpable defect, & Thomson’s test positive

What are the symptoms of soleus strain?

Pain with active or resisted plantar flexion
Pain during walking, running, jumping or hopping
Tenderness on palpation of the injury site
Muscle pain when flexing ankle or pointing toes.
Problems bending knee.
Snapping or popping sensation in calf.
Sudden pain in the back of lower leg.
Swelling in calf muscle.
Bruising on calf muscle.

How is a soleus strain diagnosed?

It becomes too challenging to identify this muscle injury just from a physical examination.
So doctors typically use an MRI & ultrasound to confirm the diagnosis of the muscle injury.

Ultrasound = USG is less good at detecting this type of muscle injury.

The doctor also asks the patient about the symptoms & tries to know about the causes of the injury.

Assessment

Subjective assessment

history with associated symptoms
mechanism of injury:
Inciting trauma- side and magnitude of injury force
recurrent trauma-faulty postural related injuries

Objective assessment

Examine the foot and ankle in supine and standing position
Ankle Active range of motion
Ankle Passive range of motion
Resisted strength check the ankle and foot
Knee Active ROM and manual muscle testing

On objective assessment, there will be:
muscle Tenderness- to touch at the point of injury
Swelling
Bruising may appear within hours or days
Stretching of the muscle will reproduce pain
Pain on resisted plantar flexion.

Differential diagnosis of soleus strain

Medial leg bone stress syndrome
Plantar fasciopathy
Ankle Joint sprain
Medial leg bone stress syndrome
Leg injuries related to sports with same symptoms and treatment as a calf strain are mentioned below.
Chronic exertional compartment syndrome (CECS)
Achilles tendinopathy
Popliteal Artery entrapment Syndrome (PAES)

What is the treatment of soleus strain?

RICE principal:

R- rest
I- ice for cooling
C- compression: tapping and splinting
E- elevation

Rest: Refused some activities that cause pain, swelling, or discomfort. don’t avoid all physical activity.

Ice: Ice is a tried-and-true tool for decrease pain and swelling. Apply an ice pack (covered with a light, absorbent towel to help prevent frostbite) for 15-20 minutes every 2 to 3 hours during the first 24 to 48 hours after injury.

Compression: This means wrapping the injured part to prevent swelling. Wrap the affected part with an elastic medical bandage. You should to be snug but not too tight.if it’s too tight, it’ll interrupt blood flow. If the skin under the wrap turns blue or feels cold,numb, or tingly, loosen the bandage. If these symptoms don’t disappear right away, seek instantly medical help.

Elevation: Elevate the leg on high of your heart’s extent, importantly at night time, that allows gravity to help reduce swelling.

Medical treatment

Pain reliving medicine mainly Non-Steroidal Anti-Inflammatory Drugs (NSAIDs) — during the first 48 hours after a muscle strain. Acetaminophen (Tylenol) and others can be helpful for pain relief during this period.

Physiotherapy Treatment and Exercise:

The goal of physiotherapy treatment are:

Relieve soleus muscle pain
Reduce muscle swelling
Increases soleus muscle strengths.
restore patient’s confidence
restore patients’ full functional activities
increase full mobility of the ligament and corresponding joint

Massage

When in the soleus muscle pain presents to tender & trigger points in the physiotherapy treatment therapist is advised to massage the area of muscle pain.
It is applied with the help of oil & powder for 5 to 10 minutes to the area of muscle pain.
Effleurage massage is mostly help to relive muscle pain.
It is applied in a circular motion. It is also applied with the help of a messenger.

Electrotherapy

physiotherapy rehabilitation can be begin after 48 hours of injury, For the first few days give electric modality give to reduce swelling and pain

Ultrasound

ultrasound has been used about tissue healing increases blood circulation and mobility & reduce swelling.

Cryotherapy

Inflammation and swelling can be decrease by applying cryotherapy in form of ice packs, and cold water baths to the affected part. Constant application of cold several times a day for 15-30 minutes at a time is suggest.

TENS or IFT

Trans cutaneous electrical nerve stimulation (TENS) or Interferential therapy(IFT) may be able to help decrease pain and muscle spasms.

Stretching of soleus muscle:

Stretching is helpful to you for releasing the muscle tightness & pain.

Soleus Stretch (Flexibility).

Must be Keep both heels on the floor.
Hold for this position for 30 to 60 seconds. Then relax both legs.
Repeat the exercise 3 times.
Then Switch legs & repeat.
Repeat this stretching 3 times a day.

Standing Soleus Stretch :

You are in a Standing position for the stretch & take a half step forward.
Must be Keep the weight evenly distributed on both feet & heels on the ground.
Slowly bend the knee joint & sink toward the ground.
In this position, You should feel a stretch in the back leg, just above the heel.
Then Continue to sink slowly with the hip joint to deepen the stretch.
Hold this stretching position for 30 seconds & change sides.
When you bend your knee joint, it is targeted to stretch the soleus & Achilles tendon rather than the gastrocnemius muscle.

Soleus seated bent-knee stretch :

You are sitting on the floor bend one knee joint & point the toes up towards the ceiling.
Hook a band & towel around the middle of the foot.
Then Pull on the band & towel to feel the stretch.

Strengthening exercise for soleus muscle :

You are standing with the feet are shoulder-width apart.
Then Raise the heels to the count of 2 & lower them to the count of 4.
Make sure to you are on the tips of your toes.
Use a chair & wall for support if you need it.
Do the 10 to 20 repetitions of 2 to 3 sets daily.
To make this exercise harder, try doing this exercise on one leg.

Single-Leg Calf Raises With Bent Knee On A Step:

You are standing on a step with the heels hanging off the edge.
Hold the something for stability
Then Stand on the leg you want to for exercise & bend the knee joint to as close the 90 degrees as you can.
Next, raise onto the toes & slowly lower back down till you get a stretch in the calf muscle & repeat.
If you are ready for this exercise more times then add weight to the hand.
Then Choose a resistance that is high for strengthening & low for endurance.
Perform this exercise for 6- 10 repetitions &repeat this exercise for 3-5 sets in total for strength.
For endurance, you do this exercise for 15-25 repetitions & repeat for 3-5 sets.
You need to rest at least 3 minutes between the sets for strength & no more than 30 seconds for endurance.
You must be taken to aim the work either 2 to 3 times per session per week.

Seated soleus raises with weight:

This exercise is performed in the 3 versions like as isometric, eccentric, and concentric.

An isometric version of this exercise :
This exercise involves holding this right foot tiptoe position for up to 30 seconds.
Then the weight needs to be heavy enough to allow no more than 30 seconds.
Once you feel stronger from this exercise & do this exercise over 30 seconds then you will add more weight.

An eccentric version of this exercise :
This exercise involves holding this right foot tiptoe position for 2 seconds.
Then slowly lowering the heel back down over the edge of the step for 3 seconds.
Repeat this movement by using the two feet to lift the weight, one foot to hold & lower, and so on.
The weight needs to be heavy enough to allow no more than 12 repetitions.
Once you feel stronger for this exercise & do the 12 repetitions & you add more weight.

A concentric version of this exercise
In exercise involves using just one foot to lift & lower the weight.
Must be Keep the tempo slow & controlled & use enough the weight to allow no more than 12 repetitions.
Once you feel stronger for this exercise & do the 12 repetitions & you add more weight.

Preventive measures:

Do Regular stretching and strengthening exercises for your sports, fitness, or work exertion, as a part of an overall physical activities
An exercise program can help to minimize your danger of muscle strains.
Try to be in a shape to play your sport; don’t play your sport to get in shape.
If you have a physically demanding occupation, regular exercise can help to help injuries.
Follow a healthy diet and an exercise program to maintain a healthy weight. The overweight can put added pressure on the muscles, making muscle strains again probable to do.
Walk at a moderate pace for 3 to 5 minutes before doing any sports or a different physical activity.
Going this will warm up the muscles and prepare them for an increase in the intensity of the exercise.
