Hamstring Length

Hamstring length: Gluteus maximus muscle weakness (as often described in Lower crossed syndrome) can lead the hamstrings muscles to act as primary hip extensors as compensation, leading to imbalance and faulty movement. There are several ways to assess hamstring length, but here just one of them is described as in Magee (2006).

The patient is supine with hips and knees in 90°. The examiner passively straightens the lower leg. Normal length of the hamstring muscle is 90° hip position with straight knee. Less than 80° is referred as loss of hamstring extensibility that can lead to gluteus maximus and quadriceps inhibition (Page et al, 1967).
