Hamtring Injury / Pulled Hamstring

A hamstring strain is a common injury involving a tear in one or more of the hamstring muscles.  A pulled hamstring can range from mild to very severe involving a complete tear of the muscle.

Pulled hamstring symptoms

One of the most obvious symptoms of a hamstring strain is a sudden sharp pain at the back of the leg during exercise, most probably during sprinting or high speed movements. Depending on how bad the injury is the athlete will usually have to stop immediately and further participation in training or sport difficult or impossible. Often the athlete will try to play on with a pulled hamstring but this is one injury where it just isn’t possible.

Pulled hamstrings are graded 1, 2 or 3 depending on severity.  Grade 1 consists of minor tears within the muscle. A grade 2 is a partial tear in the muscle and grade 3 is a severe or complete rupture of the muscle.

Grade 1 Hamstring strain

With a grade 1 hamstring strain the athlete may have tightness in back of the thigh but will be able to walk normally. They will be aware of some discomfort and unable to operate at full speed. There will be little swelling and trying to bend the knee against resistance is unlikely to reproduce much pain.

Grade 2 Hamstring strain

With a grade 2 hamstring strain the athletes gait will be affected and they will most likely be limping. Sudden twinges of pain during activity will be present. They may notice some swelling and pain will be reproduced when pressing in on the hamstring muscle as well as trying to bend the knee against resistance.

Grade 3 Hamstring strain

A grade 3 hamstring strain is a severe injury involving a tear to half or all of the muscle. The athlete may need crutches to walk and will feel severe pain and weakness in the muscle. Swelling will be noticeable immediately and bruising will usually appear within 24 hours.

Hamstring strain causes

The hamstring muscle group consists of three separate muscles; the Semitendinosus, Semimembranosus and Biceps Femoris. During sprinting the hamstring muscles work extremely hard to decelerate the tibia (shin bone) as it swings out. It is in this phase just before the foot strikes the ground that the hamstrings become injured as the muscles are working hardest and approaching their maximum length.

A pulled hamstring rarely manifests as a result of contact. If you have taken an impact to the back of the leg it should be treated as a contusion until found to be otherwise. A strained or pulled hamstring as it is sometimes called is a tear in one or more of the hamstring muscles. Strictly speaking there are three hamstring muscles, the Semitendinosus, Semimembranosus and Biceps Femoris.

Problems with the lower back and pelvis may increase the likelyhood of suffering a hamstrings strain and should always be considered, particularly for recurrent hamstring injuries.

Pulled hamstring treatment

It is vitally important that treatment for a hamstring strain starts immediately following injury.

What can the athlete do?

The most important phase for treatment is the first 48 hours post-injury. In this time the following can be carried out by the athlete themselves:

  • Apply Cold Therapy immediately for 10-15 minutes and repeat this every hour for the first day. After this, every 2-3 hours is sufficient.
  • Use a compression bandage to minimize intra muscular bleeding and swelling.
  • Rest as much as possible with the leg elevated.
  • Stretching exercises should be done but only when pain allows. It is likely that strengthening exercises will be possible before the leg is ready for stretching.
  • Strengthening exercises should be done as soon as pain allows. Mobility exercises can help with decreasing the swelling in the area. Strengthening exercises will gradually increase the load through the muscle.

What can a Sports Injury Specialist do?

  • Advise on a full hamstring strain rehab program such as that developed for us by Premiership Football Physiotherapist Neal Reynolds.
  • Use sports massage for hamstrings to speed up recovery. Sports massage is important in the treatment and rehab of hamstring muscle injuries as massage helps correct new muscle fiber realignment and minimizes scar tissue. In addition massage can increase the blood flow to the injured area.
  • Use ultrasound and other forms of electrotherapy are often used as part of pulled hamstring treatment to aid the healing process and reduce swelling.
  • Provide mobility aids such as crutches particularly if the hamstring strain is severe. Resting it is important.
  • Provide an MRI scan to ascertain the amount of damage sustained.
  • In severe ruptures surgery may be needed to repair the muscle damage.

Patient Guide to Hamstring Injury

A hamstring injury occurs when you strain or pull one of your hamstring muscles — the group of three muscles that run along the back of your thigh.

You may be more likely to get a hamstring injury if you play soccer, basketball, football, tennis or a similar sport that involves sprinting with sudden stops and starts. Hamstring injury can occur in runners and in dancers as well.

Self-care measures such as rest, ice and over-the-counter pain medications are often all you need to relieve the pain and swelling associated with a hamstring injury. Rarely, surgery may be needed to repair a torn muscle.

SYMPTOMS OF HAMSTRING INJURY:

A hamstring injury typically causes a sudden, sharp pain in the back of your thigh. You might also feel a popping or tearing sensation. Swelling and tenderness usually develop within a few hours. You may also experience bruising or discoloration along the back of your leg, as well as muscle weakness or an inability to put weight on your injured leg.

When to see a doctor
Mild hamstring strains can be treated at home. But you should see a doctor if you can’t bear any weight on your injured leg or if you can’t walk more than four steps without significant pain.

CAUSES OF HAMSTRING INJURY:

The hamstring muscles are a group of three muscles that run along the back of your thigh from your hip to just below your knee. These muscles make it possible to extend your leg straight behind your body and to bend your knee. When any one of these muscles stretches beyond its limit during physical activity, injury can result.

RISK FACTORS:

Hamstring injury risk factors include:

  • Sports participation. Sports that require sprinting or running, or other activities such as dancing that might require extreme stretching, make a hamstring injury more likely.
  • Prior hamstring injury. After you’ve had one hamstring injury, you’re more likely to have another one, especially if you try to resume all your activities at pre-injury levels of intensity before your muscles have time to heal and rebuild strength.
  • Poor flexibility. If you have poor flexibility, your muscles may not be able to bear the full force of the action required during certain activities.
  • Muscle imbalance. Although not all experts agree, some suggest that a muscle imbalance may lead to hamstring injury. When the muscles along the front of your thigh — the quadriceps — become stronger and more developed than your hamstring muscles, you may be more likely to injure your hamstring muscles.

COMPLICATIONS:

Returning to strenuous activities before your hamstring muscles are completely healed might cause an injury recurrence. In some cases, a recurrent hamstring injury may be more severe than the original injury.

Hamstring strain (pulled hamstring)

A hamstring strain or a pulled hamstring as it is sometimes called is a tear in one or more of the hamstring muscles. Strictly speaking there are three hamstring muscles (Semitendinosus, Semimembranosus and Biceps femoris) which are known as the hamstring muscle group.

The role of the hamstring muscles is to bend (flex) the knee and to move the thigh backwards at the hip (extend the hip). Understanding how the hamstrings work give vital clues as to their modes of injury. Mild to severe hamstring strains are extremely common in sprinters and hurdle jumpers and in all sports that involve sprinting activities, such as football and rugby.

Symptoms of a Pulled Hamstring:

  • A sudden sharp pain at the back of the leg during exercise-most probably during sprinting or high velocity movements.
  • Pain on stretching the muscle (straightening the knee whilst bending forwards).
  • Pain on contracting the muscle against resistance.
  • Swelling and bruising.
  • If the rupture is severe a gap in the muscle may be felt.

Severity of a Pulled Hamstring:

Strains are graded 1, 2 or 3 depending on severity. Grade 1 consists of minor tears within the muscle. A grade 2 is a partial tear in the muscle and grade 3 is a severe or complete rupture of the muscle.

Grade 1: What does it feel like?

  • May have tightness in the posterior thigh.
  • Probably able to walk normally however will be aware of some discomfort
  • Minimal swelling.
  • Lying on front and trying to bend the knee against resistance probably won’t produce much pain.

Grade 2: What does it feel like?

  • Gait will be affected-limp may be present .
  • May be associated with occasional sudden twinges of pain during activity.
  • May notice swelling.
  • Pressure increases pain.
  • Flexing the knee against resistance causes pain.
  • Might be unable to fully straighten the knee.

Grade 3: What does it feel like?

  • Walking severely affected- may need walking aids such as crutches
  • Severe pain- particularly during activity such as knee flexion.
  • Noticeable swelling visible immediately.

Treatment of a Pulled Hamstring:

What can the athlete do?

It is vitally important that treatment for a pulled hamstring starts immediately following injury. The most important phase for treatment is the first 48 hours post-injury. In this time the following can be carried out by the athlete themselves:

  • Use Cold Therapy(Rest, Ice, Compress, Elevate) technique
  • Use a compression bandage to minimize intra muscular bleeding.
  • Early mobilization of the injured lower limb is vital for the correct rehabilitation of the muscle. This includes stretching and strengtheningexercises throughout the pain free range. These can aid with decreasing the swelling in the area. In addition, exercise will ensure that any new material will be laid down in correct orientation thus reducing the risk of subsequent injuries.
  • See a sports injury specialist.

What can a Sports Injury Specialist do?

  • Use sports massage techniques to speed up recovery- these are extremely important in the rehabilitation of the injury as massage breaks down the new collagen network allowing for correct fibre realignment and minimizing scar tissue. In addition massage can increase the blood flow to the injured area. Visit our sports massagepage to learn specialized massage techniques for a pulled hamstring.
  • Use ultrasoundand electrical stimulation.
  • Prescribe a rehabilitationprogram
  • Advise on specific stretches
  • Provide mobility aids such as crutches
  • Provide an MRI scanto ascertain the amount of damage sustained
  • In severe ruptures surgery may be needed to repair the damage

How is the Hamstring Strained?

During sprinting the hamstring muscles work extremely hard to decelerate the tibia (shin bone) as it swings out. It is in this phase just before the foot strikes the ground that the hamstrings, become injured as the muscles are maximally activated and are approaching their maximum length. A pulled hamstring rarely manifests as a result of contact -if you have taken an impact to the back of the leg it should be treated as a contusion until found to be otherwise.

Preventing a Pulled Hamstring:

One of the most important methods of preventing a pulled hamstring is to warm-up correctly- this has been scientifically proven to reduce the risk of hamstring strain. This should consist of some light aerobic exercise followed by stretching and sports specific drills with gradually increasing intensity.

Other factors which increase the likelihood of suffering a hamstring strain include:

  • Age: The older the individual the greater at risk to a pulled hamstring.
  • Previous Injury: Prior injuries to the hamstrings or adductor muscles can greatly increase the chance of future injury.
  • Flexibility: Research suggests that the greater the flexibility of the hamstrings the less prone they are to injury.
  • Hamstring strength: Similarly studies have shown that lack of hamstring strength is strongly linked to hamstring injury.
  • Lumbosacral nerve impingement: Nerve impingement in L5-S1 can lead to associated hamstring muscle weakness.
  • Tiredness and fitness: When a player is fatigued he/she loses coordination between certain muscle groups. The biceps femoris muscle is known to become damaged due its two portions being innervated by two separate nerves. In states of tiredness, lack of synchronization between these two nerves can lead to a mismatch in firing resulting in a pulled hamstring.
