Have you ever felt awed or admired the way a gymnast, dancer, or figure skater can bend and move their body?
What you may have been observing is hypermobility, which is an above average range of motion in one or more joints. I wanted to address this topic because joint hypermobility affects many people (about 20%), is largely unrecognized, and can have a big impact on a person’s life.Hypermobility can occur with a joint injury, skeletal differences or genetic mutation that affects the connective tissue (e.g., Ehlers-Danlos syndrome (hEDS), Marfan Syndrome, Down syndrome). Not everyone with hypermobility has symptoms. Hypermobility Spectrum Disorder (HSD) is an umbrella term which includes people who have no genetic marker for hypermobility but are symptomatic.
Common symptoms include:
- pain/stiffness in joints and muscles
- frequent joint/muscle injuries (e.g., full or partial dislocations, muscle sprains)
- fatigue
- digestive issues
- mast cell activation syndrome (MCAS)
- pelvic health and bladder issues
Regardless of the cause, knowledge, support, and lifestyle modifications can make a positive difference in symptoms and quality of life for people with HSD.
The 5-Point Hypermobility Questionnaire for adults (2013)
1. Can you now (or could you ever) place your hands flat on the floor without bending your knees?
2. Can you now (or could you ever) bend your thumb to touch your forearm?
3. As a child did you amuse your friends by contorting your body into strange shapes or could you do the splits?
4. As a child or teenager did your shoulder or kneecap dislocate on more than one occasion?
5. Do you consider yourself double-jointed?
Two or more ‘yes’ responses suggests joint hypermobility
Joint hypermobility is linked with structural differences in the brain and nervous system.
Psychiatrist and researcher Dr. Jessica Eccles found that the amygdala is larger and more reactive in people with hypermobility. The implication is that people with HSD are more prone to ‘fight or flight’ reactions and hypervigilance. Because they have a more sensitive nervous system, they are much more likely to experience anxiety, depression, and health conditions that are sensitive to physical and emotional stress, such as irritable bowel syndrome (IBS), chronic fatigue, fibromyalgia, and postural orthostatic tachycardia syndrome. POTS is a form of dysautonomia that causes increased heart rate with positional changes or extreme heat.
