What Causes Tight Hamstrings and Why Stretching Sometimes Fails
What’s really causing your patients’ “tight hamstrings” in up to 76% of patients? Find out in this new study by Pesesse et al. (2025).
The authors assessed 178 asymptomatic adults to determine whether the discomfort limiting their hamstring range of movement (ROM) was muscular or neural.
They split them into two groups, who received one of the following assessment tests:
- Straight leg raise (SLR), or
- Knee extension angle (KEA)—taking them into 90 degrees of hip flexion, then passively extending the knee.
