Hamstring muscles

The hamstring muscle isn't a single ''string.'' It's a group of four muscles that run along the back of the thigh. They allow us to bend our legs at the knee.

Hamstring strains are common and painful; and they can strike athletes of all sorts.

During a hamstring strain, one or more of these 4 muscles gets overloaded. The muscles might even start to tear. You're likely to get a hamstring strain during activities that involve a lot of running and jumping or sudden stopping and starting.

Getting a hamstring strain is also more likely if the muscles in the front of your thigh (the quadriceps) are tight as they pull your pelvis forward and tighten the hamstrings. Another reason might be weak gluteal muscles. Glutes and hamstrings work together and if the glutes are weak, hamstrings can be over loaded and become strained.

Mild hamstring strains may not hurt too much. But severe ones can be agonizing, making it impossible to walk or even stand. Pain may be accompanied by tenderness and bruising.

Minor to moderate hamstring strains eventually heal on their own. To speed the process, you can rest, manage the pain, stretch and apply electrotherapy. In severe cases where the muscle is torn, you may need surgery.


SportsMed TENS therapy

After a diagnosis of mild to moderate hamstring strain your injury management plan should include treatment as often as possible.

SportsMed is the physical therapy product we suggest to aid recovery of a moderate hamstring injury.

SportsMed electrotherapy can be used everyday - outside the clinic - for drug-free, on-demand pain relief. It is also designed and programmed to aid circulation, reduce inflammation, hasten healing and help with muscle strengthening.

  • RELIEVE mode:
    • Pain relief (modulated low and high frequency TENS; continuous, comfortable intensity)
    • Early stage injury treatment (modulated low to medium frequency ECS; continuous, low intensity)
  • RECOVERY mode - injury healing
    • Later stage injury treatment (modulated low to medium frequency EMS and ECS; surging, medium intensity)
  • EXERCISE mode - muscle strengthening
    • Rehabilitation stage (high frequency EMS; surging, medium to high intensity)
