PSOAS Strain Treatment: Causes, Symptoms, and Recovery

Understanding and Managing Psoas Strains: Causes, Symptoms, and Effective Recovery

Psoas strains are a common injury often caused by overuse or acute trauma. If you’re experiencing pain in your lower back or hip, it’s important to understand the causes of a psoas strain and its treatment options. Early intervention and proper recovery techniques can help prevent future discomfort or complications.

1. What is a Psoas Strain?

A psoas strain is an injury to the psoas muscle, which is a long, thick muscle that runs along the spine from the lower back to the hip. The psoas muscle is responsible for flexing the hip and rotating the thigh outward. Psoas strains are relatively common, especially among athletes and people who engage in activities that require repetitive hip flexion, such as running, cycling, and weightlifting.

The severity of a psoas strain can vary from mild to severe. Mild strains may cause only minor pain and discomfort, while severe strains can make it difficult to walk or perform other activities that require hip flexion. In some cases, a psoas strain can also lead to nerve damage, which can cause numbness or tingling in the leg.

Risk factors for developing a psoas strain include:

  • Overuse: Repetitive hip flexion activities, such as running, cycling, and weightlifting, can put excessive strain on the psoas muscle and increase the risk of injury.
  • Tight hip flexors: Tight hip flexors can limit the range of motion in the hip, which can increase the risk of straining the psoas muscle.
  • Weak core muscles: Weak core muscles can make it difficult to stabilize the pelvis and spine, which can put more stress on the psoas muscle.
  • Previous psoas strain: People who have had a previous psoas strain are more likely to experience another strain in the future.

Anatomy of the Psoas Muscle

The psoas muscle is a long, thick muscle that runs along the spine from the lower back to the hip. It is responsible for flexing the hip and rotating the thigh outward. The psoas muscle is innervated by the lumbar plexus, which is a network of nerves that originates in the lower spine.

The psoas muscle is divided into two parts: the psoas major and the psoas minor. The psoas major is the larger of the two muscles and is responsible for most of the hip flexion and external rotation. The psoas minor is a smaller muscle that is located deep to the psoas major. It assists the psoas major in hip flexion and also helps to stabilize the spine.

The psoas muscle is an important muscle for movement and stability. It is used in a variety of activities, including walking, running, and jumping. It is also important for maintaining good posture and balance.

Here is a summary of the anatomy of the psoas muscle:

  • Location: The psoas muscle is located along the spine from the lower back to the hip.
  • Function: The psoas muscle is responsible for flexing the hip and rotating the thigh outward.
  • Innervation: The psoas muscle is innervated by the lumbar plexus.

Prevalence and Risk Factors

Psoas strains are relatively common, especially among athletes and people who engage in activities that require repetitive hip flexion, such as running, cycling, and weightlifting. The incidence of psoas strains is estimated to be between 0.5% and 5% in the general population, and it is more common in men than women.

Risk factors for developing a psoas strain include:

  • Overuse: Repetitive hip flexion activities, such as running, cycling, and weightlifting, can put excessive strain on the psoas muscle and increase the risk of injury.
  • Tight hip flexors: Tight hip flexors can limit the range of motion in the hip, which can increase the risk of straining the psoas muscle.
  • Weak core muscles: Weak core muscles can make it difficult to stabilize the pelvis and spine, which can put more stress on the psoas muscle.
  • Previous psoas strain: People who have had a previous psoas strain are more likely to experience another strain in the future.

Other factors that may increase the risk of developing a psoas strain include:

  • Obesity: Excess weight can put more stress on the psoas muscle.
  • Poor posture: Poor posture can lead to imbalances in the muscles around the hip, which can increase the risk of injury.
  • Certain medical conditions: Some medical conditions, such as arthritis and diabetes, can weaken the muscles and make them more susceptible to injury.

It is important to note that psoas strains can also be caused by acute injuries, such as falls or sports injuries. However, overuse is the most common cause of psoas strains.

2. Symptoms of a Psoas Strain

The symptoms of a psoas strain can vary depending on the severity of the injury. Mild strains may cause only minor pain and discomfort, while severe strains can make it difficult to walk or perform other activities that require hip flexion.

Common symptoms of a psoas strain include:

  • Pain in the lower back or hip
  • Pain that worsens with hip flexion or external rotation
  • Stiffness or tightness in the hip
  • Muscle weakness
  • Numbness or tingling in the leg (in severe cases)

The pain from a psoas strain can sometimes be referred to other areas of the body, such as the groin or thigh. It is also important to note that a psoas strain can sometimes be mistaken for other conditions, such as a herniated disc or a hip flexor strain.

If you are experiencing any of the symptoms of a psoas strain, it is important to see a doctor to get a proper diagnosis and treatment plan.

Pain and Discomfort

The pain from a psoas strain is typically felt in the lower back or hip. The pain may be sharp or dull, and it may worsen with activities that involve hip flexion or external rotation. In some cases, the pain may also be referred to other areas of the body, such as the groin or thigh.

The intensity of the pain can vary depending on the severity of the strain. Mild strains may cause only minor discomfort, while severe strains can make it difficult to walk or perform other activities that require hip flexion.

Referred pain is pain that is felt in a different part of the body from the source of the pain. In the case of a psoas strain, the pain may be referred to the groin, thigh, or even the knee. This is because the psoas muscle is connected to other muscles and tissues in the body, and the pain can sometimes travel along these connections.

It is important to note that the pain from a psoas strain can sometimes be mistaken for other conditions, such as a herniated disc or a hip flexor strain. If you are experiencing pain in the lower back or hip, it is important to see a doctor to get a proper diagnosis and treatment plan.

Muscle Weakness

The psoas muscle is responsible for flexing the hip and rotating the thigh outward. Therefore, a psoas strain can lead to difficulty with any activities that involve these movements.

Common activities that may be difficult with a psoas strain include:

  • Walking
  • Running
  • Climbing stairs
  • Getting out of a chair
  • Kicking a ball
  • Rotating the thigh outward

The severity of the muscle weakness will depend on the severity of the strain. Mild strains may only cause minor weakness, while severe strains can make it difficult to perform even simple tasks.

In addition to difficulty with hip flexion and external rotation, a psoas strain can also lead to weakness in the other muscles around the hip. This is because the psoas muscle is connected to other muscles and tissues in the body, and the weakness can sometimes spread to these other areas.

If you are experiencing muscle weakness in the hip or thigh, it is important to see a doctor to get a proper diagnosis and treatment plan.

3. Causes of a Psoas Strain

Psoas strains are most commonly caused by overuse or acute injuries.

Overuse

Overuse is the most common cause of psoas strains. This can occur in people who participate in activities that involve repetitive hip flexion, such as running, cycling, and weightlifting. Over time, the repeated stress on the psoas muscle can lead to a strain.

Acute injuries

Acute injuries can also cause psoas strains. This can occur in people who experience a sudden, forceful stretch or tear of the psoas muscle. Common causes of acute psoas strains include:

  • Falls
  • Sports injuries
  • Car accidents

Other risk factors

Certain factors can increase the risk of developing a psoas strain, including:

  • Tight hip flexors
  • Weak core muscles
  • Obesity
  • Poor posture
  • Certain medical conditions, such as arthritis and diabetes

It is important to note that psoas strains can occur in people of all ages and fitness levels. However, they are more common in athletes and people who engage in activities that involve repetitive hip flexion.

Overuse and Repetitive Movements

Overuse is the most common cause of psoas strains. This can occur in people who participate in activities that involve repetitive hip flexion, such as running, cycling, and weightlifting.

Running

Running is a common activity that can strain the psoas muscle. This is because running involves repetitive hip flexion, especially when running uphill or sprinting. Over time, the repeated stress on the psoas muscle can lead to a strain.

Cycling

Cycling is another activity that can strain the psoas muscle. This is because cycling also involves repetitive hip flexion, especially when climbing hills or riding against the wind. In addition, the forward-leaning position on a bicycle can put extra stress on the psoas muscle.

Weightlifting

Weightlifting can also strain the psoas muscle, especially exercises that involve lifting heavy weights from the floor. This is because these exercises require the psoas muscle to work hard to lift the weight and stabilize the spine.

Other activities

Other activities that can strain the psoas muscle include:

  • Jumping
  • Kicking
  • Climbing stairs
  • Getting out of a chair
  • Dancing

It is important to note that psoas strains can occur in people of all ages and fitness levels. However, they are more common in athletes and people who engage in activities that involve repetitive hip flexion.

Acute Injuries

Acute injuries can also cause psoas strains. This can occur in people who experience a sudden, forceful stretch or tear of the psoas muscle. Common causes of acute psoas strains include:

  • Falls

Falls are a common cause of psoas strains. This is because a fall can put sudden, forceful stress on the psoas muscle, especially if the person lands on their feet or buttocks.

  • Sports injuries

Sports injuries are another common cause of psoas strains. This can occur in a variety of sports, but it is especially common in sports that involve running, jumping, or kicking.

  • Car accidents

Car accidents can also cause psoas strains. This is because the sudden impact of a car accident can put forceful stress on the psoas muscle.

Other acute injuries

Other acute injuries that can cause psoas strains include:

  • Direct blows to the lower back or hip
  • Muscle strains or tears in the surrounding muscles
  • Fractures of the pelvis or hip

It is important to note that acute psoas strains can occur in people of all ages and fitness levels. However, they are more common in athletes and people who participate in activities that involve sudden, forceful movements.

4. Treatment for a Psoas Strain

The treatment for a psoas strain will depend on the severity of the injury. Mild strains can often be treated with home care, while more severe strains may require medical treatment.

Home care

Home care for a psoas strain may include:

  • Rest: Resting the injured muscle is essential for healing. Avoid activities that aggravate the pain.
  • Ice: Applying ice to the injured area can help to reduce pain and swelling.
  • Compression: Wrapping the injured area with an elastic bandage can help to reduce swelling.
  • Elevation: Elevating the injured leg can help to reduce swelling.
  • Over-the-counter pain relievers: Over-the-counter pain relievers, such as ibuprofen or acetaminophen, can help to reduce pain and inflammation.

Medical treatment

If the home care measures do not relieve the pain or if the strain is severe, medical treatment may be necessary. Medical treatment for a psoas strain may include:

  • Physical therapy: Physical therapy can help to strengthen the psoas muscle and improve flexibility.
  • Medication: Prescription pain relievers or anti-inflammatory medications may be necessary to reduce pain and inflammation.
  • Injections: In some cases, injections of corticosteroids may be used to reduce pain and inflammation.
  • Surgery: Surgery is rarely necessary for a psoas strain. However, it may be necessary in cases where the strain is severe or does not respond to other treatments.

RICE Protocol

The RICE protocol is a first-aid treatment for acute injuries, such as sprains, strains, and bruises. RICE stands for Rest, Ice, Compression, and Elevation.

Rest

The first step in the RICE protocol is to rest the injured area. This means avoiding any activities that aggravate the pain. For example, if you have a psoas strain, you should avoid running or cycling.

Ice

Applying ice to the injured area can help to reduce pain and swelling. Ice should be applied for 15-20 minutes at a time, several times a day. Do not apply ice directly to the skin. Instead, wrap the ice in a towel or cloth.

Compression

Applying compression to the injured area can help to reduce swelling. Compression can be applied with an elastic bandage. The bandage should be snug, but not too tight.

Elevation

Elevating the injured area can help to reduce swelling. If possible, elevate the injured area above the level of your heart.

The RICE protocol can help to reduce pain and swelling and promote healing. It is important to start the RICE protocol as soon as possible after an injury occurs.

In addition to the RICE protocol, you may also take over-the-counter pain relievers, such as ibuprofen or acetaminophen. If the pain is severe or does not improve with home care, you should see a doctor.

Medication

Over-the-counter pain relievers, such as ibuprofen or acetaminophen, can be helpful for reducing pain and inflammation associated with a psoas strain. These medications work by blocking the production of prostaglandins, which are chemicals that cause pain and inflammation.

In some cases, prescription pain relievers or anti-inflammatory medications may be necessary to reduce pain and inflammation. These medications are typically stronger than over-the-counter medications and may have more side effects.

Common prescription medications used to treat psoas strains include:

  • Nonsteroidal anti-inflammatory drugs (NSAIDs): NSAIDs are a class of medications that reduce pain and inflammation. Common NSAIDs include ibuprofen, naproxen, and celecoxib.
  • Corticosteroids: Corticosteroids are a class of medications that reduce inflammation. Common corticosteroids include prednisone and methylprednisolone.

It is important to take medication as directed by your doctor. Do not take more medication than prescribed, and do not take it for longer than necessary.

If you are experiencing any side effects from medication, talk to your doctor. Some common side effects of pain relievers and anti-inflammatory medications include:

  • Stomach upset
  • Nausea
  • Vomiting
  • Diarrhea
  • Constipation
  • Headache
  • Dizziness

If you have any underlying health conditions, such as liver or kidney disease, talk to your doctor before taking any medication.

Physical Therapy

Physical therapy can be helpful for strengthening the psoas muscle and improving flexibility. A physical therapist can teach you exercises and stretches that are specifically tailored to your needs.

Common exercises and stretches for a psoas strain include:

  • Hip flexor stretch: To perform this stretch, lie on your back with your knees bent and your feet flat on the floor. Pull your right knee towards your chest and hold it for 30 seconds. Repeat with your left leg.
  • Quad stretch: To perform this stretch, stand with your feet shoulder-width apart. Bend your right knee and grab your right foot with your right hand. Pull your heel towards your buttocks and hold it for 30 seconds. Repeat with your left leg.
  • Hamstring stretch: To perform this stretch, stand with your feet shoulder-width apart. Bend over and reach for your toes. Hold it for 30 seconds.
  • Psoas stretch: To perform this stretch, kneel on your right knee with your left foot flat on the floor. Lean forward and place your hands on the floor in front of you. Slowly slide your right knee forward until you feel a stretch in your psoas muscle. Hold it for 30 seconds. Repeat with your left leg.

It is important to perform these exercises and stretches slowly and gently. Do not push through pain. If you experience any pain, stop the exercise or stretch and consult with your physical therapist.

In addition to exercises and stretches, your physical therapist may also use other modalities to treat your psoas strain. These modalities may include:

  • Massage: Massage can help to relieve pain and muscle spasms.
  • Ultrasound: Ultrasound is a type of energy that can help to promote healing.
  • Electrical stimulation: Electrical stimulation can help to strengthen muscles and improve range of motion.

Surgery

Surgery is rarely necessary for a psoas strain. However, it may be necessary in cases where the strain is severe or chronic and does not respond to other treatments.

Surgery for a psoas strain typically involves releasing the tight psoas muscle. This can be done through an open incision or through a minimally invasive laparoscopic procedure.

Open surgery for a psoas strain is typically performed under general anesthesia. The surgeon will make an incision in the lower abdomen and release the tight psoas muscle.

Laparoscopic surgery for a psoas strain is typically performed under general anesthesia. The surgeon will make several small incisions in the abdomen and insert a laparoscope, a thin tube with a camera on the end. The surgeon will then use surgical instruments to release the tight psoas muscle.

After surgery, you will typically need to stay in the hospital for a few days. You will then need to follow a rehabilitation program to help you regain strength and flexibility in your hip.

The recovery time from psoas strain surgery can vary depending on the severity of the strain and the type of surgery that was performed. However, most people can expect to make a full recovery within a few months.

5. Recovery from a Psoas Strain

The recovery time from a psoas strain can vary depending on the severity of the strain. Mild strains may heal within a few weeks, while severe strains may take several months to heal.

Here is a general timeline for recovery from a psoas strain:

  • Week 1-2: Rest the injured muscle and apply ice to reduce pain and swelling. Avoid activities that aggravate the pain.
  • Week 3-4: Begin gentle stretching and strengthening exercises for the psoas muscle. Gradually increase the intensity of your exercises as you tolerate them.
  • Week 5-6: Return to activity gradually. Start by doing activities that do not aggravate your pain. Gradually increase the intensity and duration of your activities as you tolerate them.
  • Month 2-3: Most people will be able to return to full activity within 2-3 months of sustaining a psoas strain. However, it is important to listen to your body and rest if you experience any pain.

  • Month 2-3: Most people will be able to return to full activity within 2-3 months of sustaining a psoas strain. However, it is important to listen to your body and rest if you experience any pain.

If you experience any pain or discomfort when returning to activity, stop the activity and rest. You may also need to modify your activities or seek professional help from a physical therapist or doctor.

Preventing Recurrence

Preventing recurrence of a psoas strain involves making lifestyle modifications, performing exercises to strengthen the psoas muscle and improve flexibility, and using proper techniques when performing activities that put stress on the psoas muscle.

Lifestyle modifications

  • Maintain a healthy weight: Excess weight can put strain on the psoas muscle. Losing weight if you are overweight or obese can help to reduce your risk of developing a psoas strain.
  • Stretch regularly: Stretching the psoas muscle and the surrounding muscles can help to improve flexibility and reduce the risk of injury.
  • Strengthen the core muscles: Strong core muscles can help to stabilize the pelvis and spine, which can reduce stress on the psoas muscle.
  • Warm up before exercise: Warming up before exercise can help to prepare the psoas muscle for activity and reduce the risk of injury.
  • Cool down after exercise: Cooling down after exercise can help to reduce muscle soreness and stiffness.

Exercises

  • Hip flexor stretch: To perform this stretch, lie on your back with your knees bent and your feet flat on the floor. Pull your right knee towards your chest and hold it for 30 seconds. Repeat with your left leg.
  • Quad stretch: To perform this stretch, stand with your feet shoulder-width apart. Bend your right knee and grab your right foot with your right hand. Pull your heel towards your buttocks and hold it for 30 seconds. Repeat with your left leg.
  • Hamstring stretch: To perform this stretch, stand with your feet shoulder-width apart. Bend over and reach for your toes. Hold it for 30 seconds.
  • Psoas stretch: To perform this stretch, kneel on your right knee with your left foot flat on the floor. Lean forward and place your hands on the floor in front of you. Slowly slide your right knee forward until you feel a stretch in your psoas muscle. Hold it for 30 seconds. Repeat with your left leg.

Proper techniques

  • Use proper lifting technique: When lifting heavy objects, bend your knees and lift with your legs, not your back. Keep the object close to your body and avoid twisting your spine.
  • Wear supportive shoes: Wearing supportive shoes can help to stabilize the foot and ankle, which can reduce stress on the psoas muscle.
