Understanding Joint Hypermobility: Too Much of A Good Thing

Joint hypermobility is a condition characterized by an increased range of motion in one or more joints beyond what is considered normal. While flexibility is often seen as a positive trait, especially in certain physical activities, excessive joint mobility can lead to various health issues and chronic pain. This article aims to provide a comprehensive overview of joint hypermobility: its diagnosis, causes, risks, and management strategies.

The Paradox of Flexibility

Flexibility is often celebrated, especially in the fitness and sports communities. What is not discussed often enough is that excessive flexibility can be detrimental. The stability and integrity of our joints rely on a delicate balance between flexibility and strength. When joints are too mobile, they lack the necessary stability to function optimally, leading to increased wear and tear, pain, and potential injury. Many hypermobile individuals are drawn towards athletic endeavors that focus on flexibility, such as yoga, that only increase their hypermobility instead of counterbalancing it with activities that promote joint stability.

What Does It Mean to Be Hypermobile?

Being hypermobile means that your joints can move beyond the normal range of motion. This increased flexibility can affect one or multiple joints throughout the body. While some people may view this extra flexibility as an advantage, particularly in sports like gymnastics or dance, it can also lead to joint instability, pain, and other complications.

How Is Hypermobility Diagnosed?

Healthcare professionals typically diagnose joint hypermobility through a combination of physical examination and patient history. The Beighton score is a commonly used system to assess hypermobility. This nine-point scale evaluates the ability to perform specific movements, such as bending the thumb to touch the forearm or hyperextending the knees or elbows.

Possible Causes of Hypermobility

1. Genetic factors: Hypermobility can be inherited, often related to variations in collagen production or connective tissue disorders like Ehlers-Danlos syndrome.

2. Hormonal influences: Hormones like estrogen can affect joint laxity, which is why women are more likely to be hypermobile than men.

3. Anatomical variations: The shape and depth of joint sockets can influence mobility.

4. Neuromuscular conditions: Some neurological or muscular disorders can lead to increased joint mobility.

5. Acquired hypermobility: This can occur in a single joint due to injury, overuse, or repetitive motions.

Signs You Might Be Hypermobile

• You can easily place your palms flat on the floor while keeping your knees straight

• You can bend your thumb to touch your forearm

• You can hyperextend your elbows or knees beyond 10 degrees

• You experience frequent joint pain or dislocations

• You're exceptionally flexible compared to your peers

Is Hypermobility Genetic?

Yes, hypermobility can be genetic and often affects multiple joints throughout the body. Inherited forms of hypermobility are typically associated with connective tissue disorders and can impact not just joints, but also skin elasticity, blood vessel integrity, and other body systems.

However, it's also possible to have localized hypermobility in a single joint, often due to injury, overuse, or repetitive motions. For example, gymnasts may develop hypermobility in their wrists or shoulders due to the nature of their sport.

Long-Term Risks of Hypermobility

1. Increased risk of osteoarthritis: Research has shown that individuals with hypermobile joints are at a higher risk of developing osteoarthritis earlier in life. A study published in the journal "Rheumatology" found that hypermobile individuals had a significantly higher prevalence of osteoarthritis in their hands and knees compared to those without hypermobility.

2. Chronic pain: Joint instability can lead to chronic pain, particularly in weight-bearing joints.

3. Increased risk of injuries: Hypermobile individuals are more prone to sprains, strains, and dislocations.

4. Fatigue: The extra effort required to stabilize joints can lead to increased fatigue.

5. Proprioception issues: Hypermobility can affect one's sense of joint position, potentially leading to balance problems and increased fall risk.

Therapeutic Exercises to Combat Hypermobility

The primary goal of exercises for hypermobile individuals is to improve joint stability and muscle strength without increasing flexibility. Here are some evidence-based approaches:

1. Isometric exercises: These involve contracting muscles without moving the joint, which can help improve stability. For example, wall sits or planks.

2. Proprioceptive training: Exercises that improve balance and body awareness, such as standing on one leg or using a wobble board.

3. Resistance training: Using weights or resistance bands to build muscle strength around joints. Focus on controlled movements and proper form.

4. Low-impact cardiovascular exercises: Activities like swimming or cycling can improve overall fitness without putting excessive stress on joints.

5. Core strengthening: A strong core helps stabilize the entire body, reducing stress on individual joints.

The Risks of Over-Stretching

For hypermobile individuals, excessive stretching can exacerbate joint instability and potentially lead to injury. A study published in the "Journal of Strength and Conditioning Research" found that static stretching before exercise can temporarily reduce muscle strength and power, which could be particularly problematic for those with hypermobility who already struggle with joint stability.

The "Need to Stretch" Paradox

Feeling a constant need to stretch might actually be a sign of muscle weakness or joint instability rather than tightness. Research published in the "British Journal of Sports Medicine" suggests that what many people interpret as muscle "tightness" could be the body's protective response to instability. In these cases, strengthening exercises are often more beneficial than stretching.

Strengthening: A Better Alternative

For most hypermobile individuals, focusing on strengthening exercises rather than stretching is key to managing symptoms and preventing complications. A study in the "Journal of Manual & Manipulative Therapy" found that a strength training program significantly reduced pain and improved function in individuals with joint hypermobility syndrome.

Conclusion

While being flexible can be advantageous in many situations, hypermobility comes with its own set of challenges and risks. If you're physically active, experience chronic pain, and find that traditional approaches to flexibility and fitness aren't helping, you may be dealing with hypermobility. 

The key to managing hypermobility lies in finding the right balance between flexibility and stability. This often means focusing more on strengthening exercises and less on stretching. By working with healthcare professionals and adopting an appropriate exercise regimen, you can better manage your hypermobility, reduce pain, and lower your risk of long-term complications.

Remember, what works for others may not work for you. Listen to your body, and don't hesitate to seek professional guidance to develop a personalized management plan for your hypermobility.
