Introduction

Many individuals utilize their lower muscles to move around and stay active as each muscle does its job and allows mobility to the hips and thighs. In sports, the thigh muscles are utilized constantly to extend the legs and bend the knees, allowing a powerful force to win any sports competition. At the same time, various sports injuries can occur to the hips, thighs, and legs and can affect the muscles causing pain and discomfort to the lower extremities. A hamstring injury is one of the most common injuries that can affect the thighs, which can cause many athletes to be taken out of their favorite sport to recover from the injury. Today’s article looks at the hamstring muscle, how trigger points correlate with a hamstring strain, and how various stretches can reduce muscle strain on the hamstrings. We refer patients to certified providers who incorporate multiple methods in the lower body extremities, like upper thigh and hip pain treatments correlating to myofascial trigger point pain, to aid individuals dealing with pain symptoms along the hamstring muscles. We encourage and appreciate patients by referring them to associated medical providers based on their diagnosis, especially when appropriate. We understand that education is an excellent solution to asking our providers complex questions at the patient’s request. Dr. Jimenez, D.C., utilizes this information as an educational service only. Disclaimer

What Are The Hamstring Muscles?

 

Do you experience pain in the back of your upper thigh? When walking from one place to another, do you hear a popping sound in the back of your thigh? Or are you dealing with muscle tenderness in the back of your upper thigh? Many of these symptoms correlate with issues affecting the hamstrings causing trigger points to affect the upper thighs. As one of the most complex muscles comprising three muscles (semitendinosus, semimembranosus, biceps femoris), the hamstrings play a crucial part in daily activities. From simple actions like standing to explosive movements like sprinting or jumping, the hamstrings are known as posterior thigh muscles that begin from the pelvis and run behind the femur bone and cross the femoroacetabular and tibiofemoral joints. The hamstring muscles in the body play a prominent role in hip extension and is a dynamic stabilizer of the knee joint. To that point, the hamstring muscles are the most susceptible muscle that succumbs to injuries that can lead to disability in the legs and affect daily activities.

 

Hamstring Strain & Trigger Points

 

Since the hamstrings are the most susceptible muscles that can succumb to injuries, it takes a while for the muscle to heal, depending on the severity of the damage. Studies reveal that the hamstrings can occur injuries when a person is running or sprinting due to their anatomic arrangement, which causes the muscles to strain. To that point, depending on how much force has impacted the hamstrings, the injuries can lead to 3 of the following:

• Grade 1: Mild pain or swelling (no loss of function)
• Grade 2: Identifiable partial tissue disruption with moderate pain and swelling (minimal loss of function)
• Grade 3: Complete disruption of the tissue with severe pain and swelling (total loss of function)

The pain that patients experience can be painful when walking, causing them to limp. In “Myofascial Pain and Dysfunction,” written by Dr. Janet G. Travell, M.D., stated that when patients are dealing with pain in their hamstrings, it could potentially be associated with trigger points along the three muscles, causing pain and disability in the upper thighs. The book also mentioned that when trigger points affect the hamstrings, it can lead to muscle inhibition, compromising hip stability. Another issue that trigger points associated with hamstring strain causes in the body are that when individuals are sitting down are likely to experience posterior pain in the buttock, upper thighs, and back of the knees. Luckily, there are various ways to reduce the pain along the hamstring muscles.

Trigger Point Of The Week: Hamstrings- Video

Have you dealt with pain along the back of your upper thighs? Does it feel uncomfortable when you are sitting down? Or do your hamstrings ache or feel tight after running for a long period? People dealing with issues in their hamstrings could be dealing with muscle strain associated with trigger points. The hamstring muscles play a vital role in the body as it allows the individual to walk, run, bend the knees and even extend the legs. The hamstring muscles are also the most susceptible to injury, causing disability to the legs. Studies reveal that trigger points associated with the hamstring muscles can lead to soreness or irritability in the muscle fibers that may interfere with the biomechanics and normal functioning of the lower limbs. The video above explains where the hamstrings are located and how the trigger points can cause referred pain to the hamstrings. To that point, trigger points can affect a person’s ability to walk and affect the surrounding muscles in the lower body while mimicking other chronic conditions.

Various Stretches To Reduce Muscle Strain On The Hamstrings

 

When the hamstrings become injured, the healing rate usually depends on how severe the injury is in the hamstrings. If a hamstring injury is mild, the tears or strains can heal within about three to eight weeks, and if the hamstring injury is severe, the tears or strains could be long as three months. When the hamstrings are tense and on the verge of tearing, many people should stop overusing the muscle. Various stretches can reduce muscle strain on the hamstrings and relieve tension from the hamstrings to allow mobility back to the legs. Studies reveal that manual ischemic compression on the upper thigh muscles can significantly reduce pain in the lower limbs. This allows the individual to manage the trigger points associated with the hamstrings and reduce the chances of them re-occurring in the legs.

 

Conclusion

As the most important muscle in the lower body extremities, the hamstrings play a crucial part in the body as they allow the individual to walk, run, and stand without feeling pain. However, even though they are important muscles, they are susceptible to injuries. When the hamstrings become injured, the recovery process varies depending on the severity and can develop trigger points along the muscle fibers. To that point, it causes referred pain along the upper thigh muscle and affects a person’s ability to walk. Fortunately, incorporating various stretches to the hamstrings can alleviate the pain and reduce the trigger points from re-occurring in the muscle. This allows mobility back to the legs, and many individuals can resume their daily activities.
