Does Stretching the Hamstrings Fix Low Back Pain? A Physiotherapy Perspective

Many people assume that tight hamstrings cause low back pain and that stretching is the key to relief. While it’s true that individuals with back pain often have tight hamstrings, the idea that stretching them will fix the issue is a misconception. Let’s dive into the connection between hamstrings, back pain, and effective physiotherapy treatment.

The Misconception: Tight Hamstrings and Low Back Pain

A common test for hamstring flexibility is the Straight Leg Raise (SLR) test. If you can’t lift your leg beyond 80 degrees without discomfort, you may be considered to have tight hamstrings. Traditional approaches often suggest stretching to improve flexibility. However, research shows that the effects of stretching are typically short-term, with any increase in flexibility returning to baseline within hours.

How Stretching Really Works

Stretching doesn’t actually lengthen muscles but rather improves your body’s tolerance to the stretch. Long-term flexibility gains are more about how your nervous system adapts to discomfort than actual changes in muscle length. This is why stretching your hamstrings, while feeling beneficial in the moment, is not the long-term solution to low back pain.

Low Back Pain and Hamstring Flexibility

It’s common to find reduced hamstring flexibility in people with low back pain, but this limitation isn’t caused by muscle tightness. Instead, it’s the result of the body’s nervous system reacting to pain, which restricts movement. Simply stretching the hamstrings won’t resolve this issue because the lack of flexibility is a symptom, not the root cause.

A Better Physiotherapy Approach to Low Back Pain

For individuals experiencing low back pain, focusing solely on hamstring stretches can be ineffective. Instead, the treatment plan should prioritize:

• Pain reduction by avoiding painful movements.
• Core stability exercises that support the spine.
• Improving movement quality, especially engaging the glutes and hips correctly during physical activity.

This approach emphasizes long-term pain relief and functional movement improvement rather than just short-term flexibility.

Rethinking Hamstring Stretches for Athletes

Athletes often exhibit tight hamstrings as a functional trait that may enhance their performance. In some cases, static stretching for long durations can even reduce strength, power, and speed. A more effective method is to focus on dynamic warm-ups that increase muscle temperature and improve elasticity, without negatively impacting performance.

Final Thoughts: When to Stretch and When to Stabilize

Stretching should be personalized, particularly for those with chronic low back pain. For these individuals, the focus should shift towards back stabilization and improving overall movement patterns. Meanwhile, athletes may benefit more from dynamic stretching routines before workouts rather than long, static stretches.

Incorporating the right techniques into your physiotherapy program is essential for preventing injury and enhancing performance. If you’re dealing with low back pain or tight hamstrings, consult a sports physiotherapist to create a treatment plan tailored to your needs.
