Joint Hypermobility
Syndrome

If you have ever entertained your friends with body contortions, excelled at ballet, yoga or gymnastics, or been called “double-jointed,” you may have hypermobile joints that are able to extend beyond what is considered normal range of motion. The condition affects up to 15 percent of the population, and women are three times more likely to be hypermobile than men.
Many people with hypermobile joints experience few problems, but for some, hypermobility can cause pain and instability during physical activity, a condition called joint hypermobility syndrome, or JHS.
While hypermobiliy can be advantageous in certain sports and activities, hypermobile joints can be highly unstable, making you vulnerable to injury. As you age, joint hypermobility can contribute to balance issues that increase your risk of falling. In older adults, hypermobile joints are more prone to osteoarthritis from wear and tear.

Joint Hypermobility Causes

Loose or elongated ligaments within the joint capsule are the primary cause of hypermobile joints. The condition is largely hereditary, resulting from longer than normal ligaments, or from overly elastic connective tissue. Weak or overstretched muscles and connective tissue can contribute to hypermobility.
Joints that are most prone to hypermobility include:
  • ankles
  • knees
  • shoulders
  • wrists
  • fingers
  • elbows
While hypermobility imposes the greatest risk to joints of the extremities, it can also affect the head, neck, trunk and low back. Activities that demand extreme joint range of motion like dance, gymnastics and yoga can increase joint hypermobility.

Joint hypermobility syndrome symptoms

Many hypermobile people never report health problems associated with lax joints, while other experience symptoms ranging from nagging to severe.
Hypermobility symptoms include:
  • Stiff painful joints and muscles
  • Joints that click or pop
  • Frequent dislocated joints
  • Fatigue
  • Recurrent sprains or other injuries
  • Digestive issues
  • Thin stretchy skin
When occurring in conjunction with hypermobility, these symptoms indicate JHS.

Ehlers-Danlos Syndromes (EDS)

One unique subset of JHS are Ehlers-Danlos Syndromes, a group of connective tissue disorders characterized by hypermobile joints, hyperelastic skin and fragile tissues. To date, 13 subcategories of Ehlers-Danlos Syndrome have been identified, each with its own peculiar characteristics. The syndromes are thought to be hereditary, and many symptoms overlap from one category to the next.
Most symptoms of Ehlers-Danlos Syndromes affect the joints and skin, which are often fragile and painful:
  • Joints: Joints are loose and unstable, and often painful and prone to dislocation.
  • Skin: Skin is velvety-soft and tears and bruises easily; wounds heal slowly.
  • Less common: Fragile arteries, intestines and uterus; scoliosis, poor muscle tone, mitral valve prolapse and gum disease.

Diagnosis of JHS

In addition to a health history and clinical exam, your therapist may ask you a number of questions, including:
  • Can you bend forward and place your palms flat on the floor without bending your knees?
  • Does your thumb bend back far enough to touch your arm?
  • Can you perform a full split
  • Are you prone to dislocation of shoulders, elbows or knees?
  • Have you been called “double jointed?”
Your therapist may use a goniometer to measure your joint angles, and they may use diagnostic ultrasound to view your joints and muscles in motion.

Hypermobility physical therapy treatment

There is no cure for JHS, but you can manage your condition with physical therapy and exercises designed to balance muscle tension and increase joint stability. Your therapist may use real time ultrasound to help you activate and retrain deep muscles to improve overall stability. Postural correction therapy can help protect your joints by putting them in proper alignment to reduce excessive stress. Gait analysis and retraining can identify and correct motor deficiencies that increase your risk of injury while walking or running.
For athletic and physically active individuals, a therapist can design an individualized training program specific to your sport or activity, to increase joint stability and reduce your risk of injury. Athletic taping, elastic bandages or padding may add increased protection.
If you are hypermobile, you can take a proactive approach to increase your joint stability and reduce your risk of injury. A physical therapist can prescribe a personalized exercise regimen to help you achieve optimal joint function and mobility.
