Hamstring injuries are a common injury among athletes, particularly those involved in sports that require sudden changes of direction, explosive acceleration, and high-speed running. Rehabilitation after a hamstring injury can be a challenging process, and it is essential to understand the special considerations involved in the rehabilitation process to ensure optimal outcomes. The latest evidence has shown hamstring injuries require assessment and treatment of multiple areas of the body such as lumbopelvic control, posterior chain strength and stability and hamstring strength in a fatigued state. Due to the complex nature of hamstring injuries and their relationship with the aforementioned areas, they have a high recurrence rate. In this blog, we will discuss the special considerations for hamstring rehabilitation. The Importance of Early Intervention One of the most critical special considerations for hamstring rehabilitation is the importance of early intervention. Delaying rehabilitation can prolong the recovery time and increase the risk of re-injury. Therefore, it is essential to initiate rehabilitation as soon as possible after the injury. Gradual Progression Another important consideration for hamstring rehabilitation is the need for gradual progression. It is crucial to progress rehabilitation exercises slowly and steadily, focusing on regaining strength, flexibility, and mobility while avoiding overloading the hamstring muscles. Eccentric Exercises Eccentric exercises are particularly effective for hamstring rehabilitation. These exercises involve lengthening the muscle while it is under tension, which helps to promote muscle fibre remodelling and healing. Eccentric exercises can also help to improve muscle strength and reduce the likelihood of recurrence. Sports-Specific Rehabilitation Rehabilitation exercises should be tailored to the specific requirements of the athlete's sport. For example, athletes involved in sports that require high-speed running may benefit from incorporating high-speed running drills into their rehabilitation program. This approach can help to improve neuromuscular control, endurance, and power. How Can High-Speed Running Help with Hamstring Rehabilitation? The use of high-speed running as a rehabilitation strategy for hamstring injuries is based on the principle of progressive loading. High-speed running involves significant eccentric loading of the hamstring muscles, which can help to stimulate muscle fibre remodeling and improve muscle strength and endurance. Evidence for High-Speed Running for Hamstring Rehabilitation Several studies have explored the use of high-speed running as a rehabilitation strategy for hamstring injuries, with promising results. A systematic review published in the British Journal of Sports Medicine evaluated the effectiveness of high-speed running in the rehabilitation of hamstring injuries. The review analysed seven studies with a total of 301 participants. The review found that high-speed running was effective in improving hamstring strength, running performance, and reducing the risk of re-injury. The review also found that high-speed running did not increase pain or re-injury risk compared to traditional rehabilitation programs. Another study published in the Journal of Orthopaedic and Sports Physical Therapy evaluated the effectiveness of high-speed running in the rehabilitation of elite soccer players with hamstring injuries. The study found that high-speed running was effective in reducing the time to return to play, improving hamstring strength, and reducing the risk of re-injury. The Role of Manual Therapy Manual therapy can also be beneficial for hamstring rehabilitation. Soft tissue mobilisation techniques, such as soft tissue release, can help to improve blood flow, reduce muscle tension, and promote tissue healing. Joint mobilisation techniques around the lumbar spine and pelvis can also help to improve joint mobility, reducing the risk of further injury. This is integral as we work on ensuring the lumbopelvic region is working efficiently to allow the hamstrings to rehabilitate to their full potential. Psychological Considerations Recovering from a hamstring injury can be a frustrating and challenging process, and psychological considerations should also be taken into account during rehabilitation. It is common for people to experience the highs and lows of rehab & may benefit from working with a sports psychologist to help them cope with the emotional and psychological challenges of rehabilitation and stay motivated throughout the process. This is also integral for return to sport considerations as it can be a daunting experience after injury. Concerns of re-injury or not being able to perform at their pre-injury level is often felt and thus it is important for people to feel confident and mentally prepared to return to sport following a hamstring injury. Conclusion Hamstring rehabilitation requires special considerations to ensure optimal outcomes. Early intervention, gradual progression, eccentric exercises, sports-specific rehabilitation, manual therapy, and psychological considerations are all essential elements of an effective rehabilitation program. It is essential to work with a physiotherapist to develop a personalised rehabilitation program tailored to the athletes specific needs and goals.

Application and benefits during rehab. Blood flow restriction (BFR) training involves restricting the blood flow to working muscles during exercise, resulting in hypoxia in the muscle tissue. It can be applied to both resistance and aerobic exercise; however, the purpose of this blog is to have a look at the potential benefits of using BFR during resistance-based exercise in rehab. BFR resistance training has been shown to help increase muscle size and strength in young, old and load compromised populations (including post ACL replacement surgery and people suffering from OA). The greatest benefits of BFR training have been shown to occur during low-load resistance exercise, with some studies showing that muscle hypertrophy and strength adaptions using BFR are significantly greater than those achieved with low load resistance exercise alone. Benefits of BFR during rehab After sustaining an injury or having surgery, people will often struggle tolerating heavy loads through the affected area, which can cause an increase in pain during activity, reduce function and impact rehab and recovery timeframes. During rehab for any type of injury, it is important to load and strengthen the muscles around the injured or painful structure, however pain (and injury) can often prevent a person from being able to perform the required exercises (or tolerate the required load during exercise) to actually achieve this increase in strength, which can often lead to slow progression during rehab. This is where BFR training can be beneficial. BFR training can be used to get the most out of low-load resistance training for load compromised people who can’t tolerate heavy-load training during the early stages of rehab. Applying BFR training to rehab As mentioned above, BFR training can be a useful tool when trying to maximise the impact of low-load exercise during rehab. This can often be beneficial when pain/injury is impacting the ability to appropriately load the injured area in order to elicit a change in symptoms. A good example of this presentation in the clinic is during rehab following a patella dislocation or subluxation. The sensitivity and reduced capacity to load the patellofemoral joint after this type of injury can make it hard to perform quadriceps strengthening exercises with adequate load to elicit a meaningful change in strength, which can lead to the development of compensatory strategies and slow progression during rehab. BFR can be used to help overcome this hurdle. Have a look at our Instagram here to see an example of a rehab session using BFR for a client who suffered a patella dislocation. There are many other types of pain/injury that could benefit from the use of BFR at certain stages of rehab, such as managing OA pain and when recovering from ACL replacement surgery. Overall, BFR can be a useful tool to use during certain stages of rehab; but just like all aspects of rehab there is no ‘one size fits all’ approach, so get in contact in you would like to discuss if BFR could be useful for you.
