Physiotherapy for Hamstring Tendinopathy: Symptoms and Rehabilitation

Hamstring tendinopathy is a condition that affects the tendons attaching the hamstring muscles to the pelvis, thigh bone, and knee. While it often impacts athletes, anyone can experience this painful condition. With the right physiotherapy approach, full recovery and a return to normal activity levels are achievable. This article dives into the causes, symptoms, and evidence-based physiotherapy strategies for managing hamstring tendinopathy effectively.

What Is Hamstring Tendinopathy and Why Does It Occur?

Understanding the Anatomy of the Hamstrings

Before diving into how hamstring tendinopathy develops, it’s essential to understand the hamstring muscles and their role in everyday movement. The hamstrings are made up of three primary muscles at the back of the thigh: the biceps femoris, semitendinosus, and semimembranosus. These muscles work together to perform essential functions like bending the knee, extending the hip, and stabilising the pelvis.

Growing up in the local football scene in Melbourne, I saw many players struggle with hamstring injuries. Whether sprinting across the pitch or performing a rapid change of direction, the strain placed on these muscles is immense. For athletes, especially in high-intensity sports, hamstring tendinopathy often comes as part of the territory. The muscles themselves originate from the ischial tuberosity, commonly known as the “sit bone,” and attach around the knee. As a result, they’re heavily involved in movements like running, squatting, or jumping.

In simple terms, hamstrings act as the body’s shock absorbers. They help decelerate the leg during rapid movements and protect other joints like the knee from excessive strain.

Types of Hamstring Tendinopathy: Proximal vs. Distal

When it comes to tendinopathy, we typically talk about two main types: Proximal Hamstring Tendinopathy (PHT) and Distal Hamstring Tendinopathy.

Key Symptoms of Hamstring Tendinopathy: How to Recognise the Condition

Localised Pain and Aggravation with Activity

The most common symptom that my patients report is pain. It’s usually well-localised, meaning it sticks to one area – either at the sit bone (for PHT) or near the back of the knee (for distal tendinopathy). The pain tends to start as a dull ache, but in some cases, it can turn sharp, especially if you’re pushing your limits with high-intensity activities. For example, one of my long-time clients, a weekend warrior in his 30s, found that after a few laps around the oval, his buttocks would be sore for days. This wasn’t just a sore muscle; it was deep, tendon-related pain.

Understanding the “24-Hour Sign”

Another pattern that tends to crop up is the infamous 24-hour sign. Essentially, pain may ease when you’re active, but as the body cools down, the pain can flare up. It’s particularly noticeable the morning after a workout. One patient I worked with, a seasoned triathlete, noticed that while his pain would ease during his cycling sessions, by the next morning, he’d be struggling to sit comfortably for his morning coffee. This is a classic sign of hamstring tendinopathy. It’s the body’s way of signalling that the tendon is overloaded and needs time to adapt and recover.

Weakness, Tenderness, and Movement Limitations

Another significant symptom is weakness in the hamstrings. This is often most noticeable in exercises or daily tasks that require bending or straightening the knee, like squatting or running. After months of dealing with pain, my clients often report feeling weaker in their hamstrings. The tenderness is also quite palpable. In more severe cases, a noticeable bump or knot may form over the tendon’s insertion point.

I’ve seen this particularly in people who push through the pain, thinking the issue will resolve on its own. Unfortunately, that’s often when we see a deeper injury forming, as the body is simply not able to recover on its own.

The Causes of Hamstring Tendinopathy: What’s Behind the Pain?

Overuse and Compressive Loading: How Tendons Become Overloaded

At its core, hamstring tendinopathy is caused by overuse or overload of the tendon. This occurs when the load placed on the tendon exceeds its capacity to recover and adapt. This is especially common in athletes who suddenly ramp up their intensity without giving the muscles adequate time to adapt. I’ve treated plenty of athletes who push themselves too hard, too fast, like a runner who jumps straight into hill sprints without adequate conditioning. Their tendons simply can’t handle the sudden increase in load.

For PHT, compression happens when the hip is in flexion (e.g., during lunging, sitting, or deep squats). The tendon gets squeezed against the bone, irritating it. On the other hand, tensile forces are particularly evident when the hamstrings are stretched or lengthened under load, such as during running or walking. This repeated stress wears down the tendon over time, leading to pain and inflammation.

Risk Factors That Increase Vulnerability

Hamstring tendinopathy doesn’t just happen to athletes – it can affect anyone. However, there are several risk factors that can increase your chances of developing this condition. These can be either intrinsic (internal) or extrinsic (external) factors.

I’ve worked with several clients who weren’t involved in high-intensity sports but still developed tendinopathy. One client was an office worker who experienced pain from prolonged sitting, which compressed the hamstring tendon over time.

How Physiotherapy Can Help: A Structured Approach to Recovery

Initial Assessment and Diagnosis

Diagnosing hamstring tendinopathy starts with a thorough physical examination by a physiotherapist or sports doctor. This is often the most important step in getting the recovery process right. I always start by taking a detailed history of the patient’s symptoms and activities. For example, one of my clients who developed PHT after long hours sitting at his desk presented with a pain pattern that was easily identifiable once we discussed his daily habits.

Once we have a clear picture of the symptoms, I proceed with various provocation tests, such as single-leg bridge variations, to confirm the diagnosis. These tests aim to reproduce the pain and identify the specific area of the tendon affected.

Load Management: The First Step in Healing

Load management is the cornerstone of physiotherapy treatment for tendinopathy. For example, in the early stages of treatment, I often recommend my clients take breaks from activities that trigger their symptoms, such as sitting for prolonged periods or running. Instead, we focus on low-load activities that allow the tendon to recover without aggravating the injury. One useful strategy is modifying sitting posture using cushions or standing breaks. I’ve seen significant improvements when clients use a thick sponge pillow to offload pressure on the sit bones while sitting. It’s a simple change, but it can make a big difference in reducing tendon irritation.

Stages of Rehabilitation: From Pain Relief to Full Recovery

Phase 1: Pain Management & Isometric Loading

The first phase of rehabilitation focuses on reducing pain while beginning to build load tolerance. This is when isometric exercises come into play. Exercises like the Single Leg Bridge Hold are fantastic for this phase. They help activate the muscles around the tendon without causing additional strain.

For example, one client who was struggling with sitting pain during the first phase was able to perform 5 sets of 30-second bridge holds to offload the tendon and begin strengthening the surrounding muscles.

Phase 2: Progressive Tendon Loading

Once pain is minimal, we start incorporating eccentric exercises like the Nordic Hamstring Curl. The key here is slow, controlled movements that progressively build strength without compromising the tendon. A personal experience from a triathlete I worked with demonstrates how important this phase is. At first, he struggled with his regular sprint training. But after a few weeks of HSR and progressively loading his hamstring, he was back to training with minimal discomfort.

Phase 3: Functional Rehabilitation

By this phase, patients are ready to incorporate exercises that mimic the movements they perform in their daily or sports activities. Romanian Deadlifts and Walking Lunges help improve both strength and flexibility in the hamstring.

Phase 4: Energy Storage and Release for Athletes

The final phase targets plyometric exercises, essential for athletes returning to high-intensity sports. Exercises like Box Jumps and A-Skips restore the ability to store and release energy in the tendon, preparing them for activities like sprinting or cutting.

Recovery from hamstring tendinopathy takes time, patience, and a structured physiotherapy approach. With early intervention, load management, and progressive loading, patients can return to their previous level of function. Whether you’re an athlete or someone leading a more sedentary lifestyle, adhering to a comprehensive rehab plan is crucial for long-term recovery and injury prevention.

By focusing on proper diagnosis, load management, and personalised rehabilitation, recovery from hamstring tendinopathy is not only possible, but it can also be sustainable. Remember, the road to recovery isn’t always linear, but with the right approach, full recovery is within reach.
