Hypermobility Syndrome, also known as Ehlers-Danlos Syndrome Type III, is a condition that causes chronic pain, fatigue, and disability. HMS patients often experience muscle imbalances and incorrect muscle recruitment due to improper postures and joint instability. The body attempts to compensate for lax or injured joints by tightening the surrounding muscles, leading to musculoskeletal pain. Hamstring muscles, located at the back of the thigh, are particularly susceptible to injury, especially in athletes who run and sprint. These muscles are crucial for various leg movements, including walking, climbing stairs, and squats. Conditions affecting the hamstring include muscle strains, ranging from mild pulled hamstrings to severe complete tears.
| Characteristics | Values |
|---|---|
| Full Form | Hypermobility Syndrome (HMS) |
| Other Names | Ehlers-Danlos Syndrome Type III |
| Cause | HMS is caused by collagen, a major component in all soft tissues, not just the connective tissues around the joints. |
| Symptoms | Joint pain, frequent dislocations, GI problems, and OBGYN problems |
| Muscle Imbalance | HMS patients' bodies try to overcompensate for lax or injured joints by tightening the muscles surrounding the joint. |
| Self-Limitation | One of the most debilitating symptoms of HMS is self-limitation, where the fear of pain causes patients to avoid certain activities or movements altogether. |

Hamstring muscles are skeletal muscles at the back of the thigh
The hamstring muscle group is comprised of three skeletal muscles located at the back of the thigh: the biceps femoris, semitendinosus, and semimembranosus. These muscles are responsible for a wide range of leg movements, including walking, climbing stairs, running, and squatting. They are essential for everyday activities and athletic endeavours.
The biceps femoris is positioned on the outside of the back of the thigh. Its functions include flexing the knee, extending the thigh at the hip, and enabling the rotation of the lower leg from side to side when the knee is bent. This muscle is crucial for maintaining stability and facilitating dynamic movements.
The semimembranosus muscle is located on the innermost side of the back of the thigh. Similar to the biceps femoris, it also flexes the knee joint and extends the thigh at the hip. Additionally, the semimembranosus plays a role in rotating the hip and lower leg, contributing to fluid and versatile leg movements.
Sandwiched between the semimembranosus and biceps femoris is the semitendinosus muscle. It shares the same functions as the semimembranosus, working in tandem to produce seamless and controlled leg motions. The hamstring muscles contain thousands of long, elastic muscle fibres that facilitate leg muscle contractions and contribute to their striped appearance.
Due to their role in various physical activities, hamstring muscles are susceptible to injuries, especially in athletes who run and sprint. Strains, pulls, and tears can occur when the muscle fibres are overstretched or torn, resulting in pain, swelling, and potential loss of function. Proper stretching, warming up, and listening to one's body during exercise are crucial for preventing hamstring injuries.

They are used for walking, climbing stairs, and many other leg movements
The hamstring muscles are skeletal muscles located at the back of the thigh, starting at the pelvis and extending to the knee. They are used for walking, climbing stairs, and many other leg movements. These include running, squatting, and performing leg exercises.
The hamstring muscles are made up of three muscles: the biceps femoris, semitendinosus, and semimembranosus. These muscles work together to facilitate movement and stability in the leg. The biceps femoris is located on the outside of the back of the thigh, and its main function is to flex the knee, extend the thigh at the hip, and enable side-to-side rotation of the lower leg when the knee is bent.
The semitendinosus is located between the semimembranosus and the biceps femoris, and it shares a similar function to the latter. The semimembranosus, meanwhile, is situated on the innermost side of the back of the thigh. It is responsible for flexing the knee joint, extending the thigh at the hip, and facilitating rotation in the hip and lower leg.
The hamstring muscles contain thousands of long, elastic muscle fibres that enable the leg muscles to contract and tighten. This allows for a wide range of movements and helps to stabilise the leg during activities such as walking and running. However, the hamstring muscles are susceptible to injury, especially among athletes who run and sprint. Sudden changes in direction or speed can strain these muscles, leading to common injuries such as pulled hamstrings or muscle tears.

They are susceptible to injury, especially in athletes who run and sprint
The hamstring muscles are skeletal muscles located at the back of the thigh, starting at the pelvis and extending to the knee. They are used for walking, climbing stairs, running, squatting, and performing other leg movements. These muscles are particularly susceptible to injuries, especially among athletes who run and sprint.
The three hamstring muscles are the biceps femoris, semitendinosus, and semimembranosus. The biceps femoris is located on the outside of the back of the thigh and is responsible for flexing the knee, extending the thigh at the hip, and rotating the lower leg from side to side when the knee is bent. The semimembranosus is located on the innermost side of the back of the thigh and is involved in flexing the knee joint, extending the thigh at the hip, and rotating the hip and lower leg. The semitendinosus is positioned between the semimembranosus and the biceps femoris, sharing the same functions.
Athletes who engage in running and sprinting activities are particularly vulnerable to hamstring injuries due to the high demands placed on these muscles during such activities. Sudden changes in movement, such as stopping abruptly, slowing down, or changing direction, can put a significant amount of strain on the hamstring muscles. Additionally, extending the leg while running can also lead to overstretching of these muscles.
To prevent hamstring injuries, it is crucial for athletes to incorporate stretching and warming-up exercises into their routines. It is also important to listen to your body and not push through pain in the hip, knee, or leg. By taking a proactive approach to injury prevention, athletes can reduce the risk of hamstring injuries and maintain their performance and overall well-being.

Common hamstring injuries include pulled hamstrings and muscle strains
Hamstring injuries are a common occurrence, especially among athletes who participate in sports that require sprinting, like track, soccer, basketball, and waterskiing. The hamstring muscles run down the back of the thigh, starting at the bottom of the pelvis and ending near the top of the lower leg. Common hamstring injuries include pulled hamstrings and muscle strains, which can range from mild pulls to severe tears.
A pulled hamstring occurs when one or more of the muscles at the back of the thigh are injured. This can be a result of a sudden increase in physical activity, which is one of the most common causes of hamstring injuries. It can also happen when you slip and fall, performing an action like "the splits" and tearing your hamstring muscles.
A hamstring strain can be a pull, a partial tear, or a complete tear of the muscle. Strains occur when the muscle is stretched beyond its capacity or challenged with a sudden load. They can happen during a growth spurt when bones grow faster than muscles, causing the muscle to tighten and become more susceptible to injury. Muscle fatigue can also lead to hamstring strains as it reduces the energy-absorbing capabilities of the muscle.
The symptoms of a hamstring injury include pain in the back of the leg that may spread to the groin, butt, or other parts of the leg. There may also be a noticeable bump or knot in the muscle. Higher-grade strains will cause more severe symptoms, including a loss of strength in the affected hamstring. Treatment for hamstring injuries typically involves the RICE protocol (Rest, Ice, Compression, and Elevation), and most hamstring strains respond well to simple, non-surgical treatments. However, severe strains may take months to heal.

Hypermobility Syndrome (HMS) can cause muscle imbalances and incorrect muscle recruitment
Hypermobility Syndrome (HMS), also known as Ehlers-Danlos Syndrome Type III, can lead to muscle imbalances and incorrect muscle recruitment due to improper postures and poor body mechanics. HMS patients are often thought of as being "too loose," but their musculoskeletal pain can arise from chronically tight muscles as their bodies attempt to compensate for lax connective tissues. The body's attempt to overcompensate for lax or injured joints can result in tight muscles surrounding those joints. This can lead to joint instability, hyperextension, and poor posture, exacerbating the pain associated with HMS.
The fear of pain associated with HMS can cause patients to avoid specific activities or movements, leading to deconditioning of certain muscles. This deconditioning can, in turn, result in increased pain and instability over time.
Additionally, HMS can cause secondary symptoms beyond joint pain, such as frequent dislocations, subluxations, and hyperextensions. The syndrome may also affect the gastrointestinal system, leading to irritable bowel syndrome, diarrhea, constipation, reflux, gas, and stomach pain. Obstetric and gynecological issues may also arise, including irregular or heavy periods, increased joint pain during menstruation or pregnancy, and pelvic floor instability.
The treatment of HMS focuses on managing symptoms and improving quality of life. While chronic pain, fatigue, and disability are common challenges associated with HMS, they can be addressed through a combination of medical interventions and positive psychological strategies. By staying positive and accommodating current limitations, patients can devise treatment plans to overcome those limitations over time.
