5 Physiotherapy Exercises for Hamstring Injuries

Spring is just around the corner! Now that the days are getting longer and the weather is getting warmer, you might feel inspired to go for a run. Breathing in fresh air and getting out of the house for a quick jog is a great way to exercise. However, if your body is not prepared for it, running can cause several injuries and aches — especially when it comes to your hamstrings. 

Your hamstring is composed of three muscles: the biceps femoris, semitendinosus and semimembranosis. These muscles run down the back of the leg from your thigh to your knee and help you bend your knee and extend your hip. Hamstring pulls are a very common running injury and tend to occur in more active individuals. Hamstring injuries occur when one or more of the muscles in the hamstring become overloaded and end up over-stretching or tearing. 

The good news is most hamstring injuries we see at our Synergy Rehab clinics can be treated without surgical intervention.  

What causes a hamstring strain?

A major cause of hamstring strains is improper stretching. If your muscles are tight and not warmed up, they are far more susceptible to injury and strain. Another cause of hamstring strain may have to do with quad development. For the most part, many of us have stronger and larger quads than hamstrings. When running, your hamstrings are more susceptible than your quads to getting tired, which places you at a higher risk of developing a strain. 

Lastly, if your running technique is poor or you return to the gym or your activity of choice too soon without fully healing, you could also easily pull your hamstring.

Do I have a strained hamstring? 

If you have strained your hamstring, you may feel a sharp pain or even a popping sensation in the back of your leg. Afterwards, you will typically develop tenderness, bruising or swelling in the back of your thigh.

There are three different degrees of hamstring strains. 

If you have a grade one strain, you may have mild swelling or spasms. While you may not be able to run at full speed, you will be able to walk normally, despite feeling some tightness in the back of your thigh. 

A grade two injury may cause you to limp. Your hamstring may be throbbing, tender and you may notice some swelling. Pain will arise as well if you bend your knee against resistance. 

The most severe level is a grade three, which involves a complete tear to half or all your hamstring muscle. With this type of injury, you will need a walking aid, such as crutches, and you will experience severe pain.

Top 5 Exercises for Hamstring Strains

Here are the top five physiotherapy exercises and stretches that help heal a grade one to grade two hamstring strain. These exercises should only be performed if daily activities such as walking do not lots of cause pain. If you ever feel sharp pain at any point, stop. You should only feel a mild discomfort, if at all. Check with your physio before adding these exercises to your healing routine!

1.     Standing Hamstring Stretch

Place the heel of your injured side on the side of a chair or stool. While keeping your leg straight, lean forward while bending at your hips. You should feel a light stretch in the back of your thigh. It is important that you do not bend your knee while doing this stretch as that will target your lower back instead. Hold this for 30 seconds and repeat a few times throughout the day. The purpose of this stretch is not to increase your flexibility but to get some elasticity to the healing tissue.

2.     Hurdler Hamstring Stretch

Sit on the floor with your left leg straight out. Bend your right leg at the knee and place your right foot on your left thigh. Reach forward with your arms over your left leg and bend your waist forward as far as possible while holding this position for ten seconds. Switch legs and repeat on the other side.

3.     Hamstring Curl

Grab a pillow to place under your belly for support while you lie on top. Start by lying on your stomach with your legs straight out behind you. On the side with the affected leg, bend your knee so that your foot is towards your buttocks. Move your leg down slowly and back up and repeat these 10 times over. If this exercise is too easy for you, add a resistance band.

4.     Lunge Stretch

Start off by stepping forward with your left leg. Dip your knee so that it is at a 90-degree angle. This stretch will strengthen the quads which are the muscles in the front of your thigh. Do not attempt this stretch at the beginning of your injury but rather later in your recovery when you’re feeling stronger.

5.     Bent Knee Stretch

Lie on your back and lay one your left leg on the floor and your right leg up in the air. Clasp your fingers behind your right thigh and bring your leg closer to your chest until you feel a light stretch in the back of the leg. Hold this for ten seconds and perform this several times a day.


How long until I recover from a hamstring strain? 

Unfortunately, the answer to this question is dependent on the severity of you hamstring strain. Recovery could take as little as a week or be as long as six months. It is important to note that if you have a severe strain, a complete rupture, or a reoccurring hamstring injury, surgery may be required. While you may feel better after a few days, it is important that you have your hamstring looked at. This will enable you to rehab it correctly to prevent the buildup of scar tissue and reduce the risk of a re-injury.

Physical Therapy aims to reduce your hamstring pain and strengthen your muscles, specifically targeting the hamstrings, knees, calves, hip and pelvis muscles. This will help increase your muscle’s range of motion, improve your function and normalize the lumbo-pelvic control, which is a contributing factor in hamstring injuries.
