When it comes to assessing hamstring strains you will find it no longer looks at grades 1-3, now you will find you are put into 1 of 2 groups.
Type 1 – This injury occurs at high speed, for example when running. Pain and disability are high in the very early stages but the length of recovery quite short. You will find you can start to jog quite early on in rehabilitation. It is usually found to be the outer hamstring (long head of biceps femoris)
Type 2 – This injury is related to over stretching the hamstring like doing a high kick or sliding tackle. The injury may not be very disabling or painful and for this reason has a high risk of re injury. This injury takes longer to recover from than a type 1. It is usually found to be the inner hamstring (semimembranosus).
Both injuries take a slightly different rehabilitation approach. You also have to take into account the site of pain, the closer it is to your ischial tuberosity (known as the sitting bone) the longer it will take to heal.
Although it is hard to give a time frame for injury recovery as everyone is different, we can start to give more information about recovery in relation to the mechanism of injury and site of injury. One study found on average it took 23 days to recover from a type 1 and 43 days to recover from a type 2. The study also looked at specific rehabilitation programs and this will be discussed in our next newsletter sent out at the end of May.
