Hamstring strain is a common injury of the hamstring muscles that results in posterior thigh pain. Like calf strain, hamstring strain commonly affects individuals who participate in high-impact sports such as football or basketball and can severely affect your ability to walk or run after.

Causes of Hamstring Strain

The hamstrings muscle group is made up of 3 different posterior thigh muscles, namely biceps femoris, semitendinosus, and semimembranosus. Hamstring strain occurs when the muscle is contracting whilst being stretched beyond its limit, causing a degree of tear in the muscle fibres.

Hamstring strain can be classified into 3 gradings:

  • Grade 1 – Mild, only a small amount of muscle fibres are torn, and the patient is usually able to walk without pain, but unable to exercise.
  • Grade 2 – Moderate, partially-torn muscle, typically results in acute pain and swelling and affects walking
  • Grade 3 – Severe, significantly torn muscle (or full rupture), resulting in loss of strength and function

Risk Factors of Hamstring Strain

Risk factors of hamstring strain include:

  • Old age

  • Tight hamstring muscles or hip flexors
  • Sudden increase in training intensity
  • Inadequate recovery
  • Muscular imbalance
